Appendix-A: Hydrogeologic Investigation Report 

1.3 BACKGROUND 

The proposed project is located west of the town of Windsor, California. As shown in Figures 1-

2 and 1-3 the undeveloped property consists of fourteen individual parcels totaling approximately 

124-acres. One parcel is within the Windsor Town limits (see Figure 1-2). Windsor River Road 

runs through and adjacent to the parcels. The site is located in slightly hilly terrain and primarily 

contains oak trees and grass understory. There are some minor dry drainages that traverse the 

site. As shown in Figure 1-3, residential development abuts this cluster of parcels in one area. 

The other lands surrounding the parcels are primarily “ranchettes” and vineyards.

1.4 HOUSING ALTERNATIVES

Three preliminary site alternatives provided by the project architect are shown in Figures 1-4, 1-

5, and 1-6. These housing alternatives have been used as the basis of this Water and Wastewater 

Feasibility Study. Each scenario has a combination of low-, medium-, and high-density 

residential housing and a combination of communal facilities such as a community center, retreat 

house, roundhouse, and ceremonial dance circle. 

1.4.1 ALTERNATIVE A

Alternative A (Figure 1-4) has a total of 147 housing units, a community center, a retreat house, a 

round house, and a ceremonial dance circle. Alternative A has been developed presuming that 

the Town of Windsor would provide the water supply and wastewater treatment for the proposed 

project. Therefore, Alternative A does not have allocated spaces for on-site water or wastewater 

treatment and storage. 

1.4.2 ALTERNATIVE B

Alternative B (Figure 1-5) has a total of 147 housing units, a community center, a retreat house, a 

round house, a maintenance yard, a ceremonial dance circle, and onsite water and wastewater 

facilities. Alternative B has been developed presuming that the water supply would be obtained 

from onsite wells. The wastewater would be treated onsite to tertiary standards, and disposed in 

one of two ways: 

Alternative B1 involves reclaiming the tertiary effluent on-site to the extent feasible, 

and discharging any remaining effluent to surface water drainage courses on the 

property that are tributary to the Russian River. 

Alternative B2 involves reclaiming all tertiary effluent on-site. During winter and 

spring, particularly under high rainfall conditions, the tertiary effluent will be stored for 

subsequent reclamation under drier weather conditions. 

This alternative assumes that landscape irrigation demands will be supplied by reclaimed water to 

reduce potable water demands.

1.4.3 ALTERNATIVE C

Alternative C (Figure 1-6) has a total of 55 housing units, a community center, a retreat house, a 

round house, a maintenance yard, a ceremonial dance circle, and onsite water and wastewater 

facilities. Alternative C has been developed presuming that the water supply would be obtained 

from onsite wells and the wastewater would be treated on-site and reclaimed on-site, like 

Alternative B2, but on a smaller scale because of the fewer housing units. Effluent generated 

during the non-irrigation season will be stored and reused during the following irrigation season.

This alternative assumes that landscape irrigation demands will be supplied by reclaimed water.

1.5 WATER DEMAND ESTIMATES 

Water demands estimated for the three preliminary site alternatives are based on a combination 

of local and regional demand factors, readily available usage data, and local 

evaporation/transpiration rates. The estimates of potable water demand are summarized in 

Tables 1-1 and 1-2.

1.6 DESIGN OCCUPANCY AND WASTEWATER FLOWS 

Occupancy of newer developments is often a little over 4 capita/EDU, even though overall 

community occupancy may be around 3.2 capita/EDU. This is because typical “newer 

developments” attract families. The high capita/EDU figure for newer developments, then, 

decreases over time as the children leave home. The Lytton housing project is not a typical 

“newer development” attracting families, it is planned to serve a specific community from 

young to old. Estimates of the number of people who will reside initially in the planned 2 to 

4 bedroom homes are not available, and will change over the life of the project. However, as 

a conservative estimate, using 147 EDUs (Alt A & B) and 57 EDUs (Alt C) and 4.2 

capita/EDU results in estimated occupancies of 617 people (Alt A & B) and 240 people (Alt 

C), plus possibly some day workers using community facilities. 

Wastewater flows from the residential buildings are estimated based on Sonoma County design 

standards (Sonoma County, 2007). The standards specify that the minimum sewage flows from 

residential buildings shall be calculated based on 120 gallons per day per bedroom, provided that 

the residence has low flow toilets and shower heads. Wastewater flows from communal facilities 

are estimated based on two different methods: 1) based on plumbing fixtures and 2) Sonoma 

County design standards. Conservatively, the larger estimated flow value was selected for 

further analysis. In the first method, the wastewater flow generation was estimated based on 

plumbing fixtures installed in each facility. In the second method, the flow generation was 

estimated based on Sonoma County design standards for various communal establishments. The 

roundhouse shown in all of the alternatives does not have any internal plumbing fixtures; 

therefore, wastewater generated from the roundhouse is assumed to be zero. Wastewater flows 

not including infiltration and inflow estimated for Alternatives A, B, and C based on Sonoma 

County design standards are shown in Table 1-3.

1.6.1 INFLOW AND INFILTRATION (I/I)

Gravity sewers will be used to convey the wastewater generated from individual homes and 

communal facilities to the wastewater treatment and reclamation (WWTRF). Gravity sewers 

have the potential to receive additional flows from infiltration and inflow (I/I) of rainfall and 

shallow groundwater before reaching the WWTRF. Infiltration refers to water seepage through 

collection system pipes and vaults, and inflow refers to surface and subsurface stormwater 

entering the collection system mirroring the character of the precipitation event. The amount of 

I/I entering a sewer system depends on numerous factors including: 1) precipitation, 2) 

groundwater levels, 3) topography, 4) soil types, 5) area runoff coefficients, 6) age of sewer 

collection system, 7) type of material used for pipe joints, and 8) construction methodologies and 

9) sewer maintenance activities over time. Sewers running near or through areas where water 

collects, e.g., stormwater drainage courses and swampy areas, are inclined to have high I/I over 

time as the sewer pipe ages. Infiltration typically influences the overall increases in annual 

volume of wastewater to be handled at the WWTRF. Inflow influences the peak day and hourly 

flows.

Analysis of possible peak day and peak hourly flows from the planned community will be 

performed during the design phase of the project as it pertains to the sizing of sewers and 

treatment processes (in the case of Alternatives B and C). However, the annual increase in 

wastewater volume caused by I/I impacts the effluent storage and disposal facility needs of 

Alternatives B or C. The incremental annual average flow increase from I/I is assumed to be 15 

percent of annual dry weather flow (ADWF) during normal rainfall years, and 25 percent of 

ADWF during 100-year design conditions. The assumption is based on 1) the sewer pipes being 

relatively shallow (more subject to damage over time), installed in a hilly setting where shallow 

groundwater may tend to collect in the backfilled sewer trenches, and old (50 years) towards 

the end of the expected lifetime of the community’s wastewater infrastructure. Best Management 

Practices (BMPs) are being developed for the Lytton project to control I/I throughout its lifetime. 

If the BMPs are followed, the foregoing I/I flow estimates may be conservative, but this will not 

be know for decades.

2.3 WATER SUPPLY FEASIBILITY EVALUATION 

2.3.1 OFF-SITE WATER SUPPLY (ALTERNATIVE A)

The proposed project is located immediately west of the Town of Windsor, California. Windsor 

has an approximate population of 25,000. In general, the majority of the town population 
Section 2 Water Supply 

Stantec Lytton Rancheria Feasibility Study

October 2010 2-2 AESS08-001

receives water from the existing municipal water supply system. The primary water supply for 

the Windsor water system is a field of wells located near the Russian River to the northwest of 

the proposed project site. Two large diameter water transmission mains transport this water from 

the well field to the Town of Windsor for distribution. One of the transmission mains, an 18-inch 

diameter water main, parallels Windsor River Road, which abuts the north boundary of the 

project site.

Technically, it appears feasible for the proposed project to connect to the existing 18-inch 

diameter water transmission main immediately north of the property. Based on this 

reconnaissance level assessment, it is likely that there is sufficient flow and pressure in the 

existing main to provide a functional water supply to the project for both potable water service 

and fire protection. Because of the water quality and reliability of the Windsor potable water 

supply system compared to the inherent limitations of a smaller, on-site potable water utility, 

connection to the Windsor potable water supply system is recommended; and Town approval for 

this plan (Alternative A) should be sought. 

2.3.2 ON-SITE WATER SUPPLY (ALTERNATIVES B AND C)

The feasibility of an on-site potable water supply necessary for Alternatives B and C was 

evaluated by performing preliminary research on local hydrogeologic conditions, performing a 

field investigation, and developing preliminary conclusions. The preliminary research included: 

Reviewing available reports that address the geology and groundwater resources in the 

vicinity of the development; 

Reviewing well logs obtained from the California Department of Water Resources to 

ascertain the distribution of water bearing geologic materials and the water-yielding 

potential of the local aquifer(s); 

Reviewing production data for wells surrounding the development to determine 

whether or not there is sufficient capacity to meet the additional demands associated 

with the project; 

Providing estimates of probable well yields; and 

Providing estimates of potential interference drawdown in neighboring wells. 

The principal aquifer in the project vicinity was determined to be comprised of alluvial deposits 

of clay, silt, sand, and gravel. Well yields from these materials are highly variable because of the 

heterogeneous composition of the information (hydraulic properties vary over small distances), 

because wells are drilled to variable depths and do not all produce from the same aquifer 

thickness. Area wells typically yield between 1 and 140 gallons per minute (gpm) with an 

average specific capacity (a measure of well performance) of about two gallons per minute per 

foot of drawdown (gpm/ft). Although this information suggests there is a possibility of meeting 

the project’s water supply needs with groundwater production wells, site-specific data were 

lacking, and the potential for new production wells to impact neighboring wells was uncertain. 
Section 2 Water Supply 

Stantec Lytton Rancheria Feasibility Study

October 2010 2-3 AESS08-001

To resolve questions developed during the preliminary research phase, a field investigation was 

conducted that consisted of the installation of a test well and a dual-completion monitoring well. 

Aquifer stress tests were then completed consisting of a four-hour step test and a 72-hour 

constant discharge test. The aquifer at the property was found to be more permeable than 

anticipated. The step test was completed at rates up to 272 gallons per minute (gpm). The 

constant discharge test was completed at 150.3 gpm. Analysis of the test data indicated that a 

production well could sustain a continuous pumping rate of 75 gpm without excessive 

drawdown, and could meet peak pumping rates of 150 gpm. The amount of drawdown in the 

well was not considered excessive because it amounted to about 10 percent of the aquifer 

thickness and because average drawdown would be maintained above the top of the screen 

interval.

The closest existing domestic well to the test well is located approximately 700 feet to the east. 

Potential interference drawdown in this well was calculated assuming it derives groundwater 

from the same strata as the test well, that there are no hydrologic boundaries present that would 

isolate the well from the test well site, and that there is no recharge to the aquifer. After 

continuously pumping a hypothetical production well for one year at a continuous rate of 

57 gpm, interference drawdown at the nearest well was calculated to be approximately 8.5 feet. 

If this offsite well derives water from shallower aquifer materials than the test well, less 

interference drawdown should be expected, on the order of three feet. At a distance of 

approximately 2,000 feet, drawdown was also calculated to be about three feet. Assuming an 

aquifer thickness of 300 feet based on the test well program, the calculated drawdown represents 

only 1 to 3 percent of available drawdown in the aquifer within this radius. Because some 

recharge to the aquifer occurs even during years of lower-than-normal precipitation, and area 

groundwater levels have been reported to be stable, the calculations are likely conservative and 

actual interference drawdown may be less. Consequently, estimated impacts to the overall 

aquifer as a result of the project are not considered significant. 

A water quality sample was collected from the test well at the end of the constant-discharge test 

and analyzed at a California-certified environmental laboratory for Title 22 parameters. The total 

dissolved solids concentration was low at 270 mg/L, but concentrations of arsenic (0.058 mg/L) 

and manganese (0.15 mg/L) did not meet California or Federal drinking water standards. 

Treatment to remove them will be required. 

2.4 PRELIMINARY LAYOUT FOR ON-SITE POTABLE WATER SUPPLY 

INFRASTRUCTURE

With either Alternative A (Town of Windsor water supply) or Alternatives B/C (on-site water 

supply) the basic piping infrastructure to distribute to potable water to the various uses sites in 

the proposed project would be similar. Common facilities for all alternatives would include the 

underground distribution piping, water services, and fire hydrants. In general, underground 

piping would consist of American Water Works Association (AWWA) pressure rated piping with 

a minimum diameter of 6 inches and be installed in accordance manufacturer recommendations 

and regionally accepted methods. The water distribution system will be designed in accordance 
Section 2 Water Supply 

Stantec Lytton Rancheria Feasibility Study

October 2010 2-4 AESS08-001

with standard engineering design practices that include providing a minimum water service 

pressure of 40 psi to each service during maximum day demand periods and at no time a pressure 

less than 20 psi during a fire flow event per 2006 International Fire Code standards. 

The actual layout of the distribution pipes and fire hydrants would be determined during final 

design. The layout would incorporate the specific location of water supply sources and the 

required fire flows approved by the local fire authority. For planning purposes, the estimated 

maximum required fire flow for the development is assumed to be 2,500 gpm for two hours. The 

estimated fire flow requirement is based on the largest structure, which would be the community 

center, and the 2006 International Fire Code fire flow requirements (International Fire Code, 

Appendix B, Section B105).

2.4.1 OFF-SITE WATER SUPPLY FACILITY LAYOUT (ALTERNATIVE A)

If the Town of Windsor provides municipal potable water to the proposed project, minimal 

facilities would be required beyond the distribution system components summarized previously. 

In addition to the distribution system components, it would be prudent to construct two water 

supply connection points into the project from the existing 18-inch diameter main along the north 

property boundary. These supply points would generally consist of a Windsor service meter 

station installed below ground in a concrete vault and an above grade backflow prevention 

device. It has been assumed for the purposes of this feasibility study that Windsor would 

consider the water system improvements on the subject property a “private” water distribution 

system and would require backflow prevention facilities at the point of connection. The meter at 

each connection would allow Windsor to account for usage by the private water system. 

2.4.2 ON-SITE WATER SUPPLY FACILITY LAYOUT (ALTERNATIVES B AND C)

An on-site water supply system would generally consist of at least two groundwater production 

wells with the wells being able to meet the maximum day demand flow with largest well out of 

service, this approach provides a reliable water supply to the project. Within the maximum 

demand day, maximum diurnal demands would be met by removing water from storage. Water 

from the groundwater production wells would be conveyed to an on-site water treatment facility 

providing arsenic and manganese removal to meet current drinking water standards. The water 

treatment facility will be sized to treat the maximum day demand design flow at a minimum and 

convey this water to the ground level water storage tank. Since the wells and the treatment 

facility can not supply the estimated fire flow of 2,500 gpm in addition to the maximum day 

demand, a 400,000 gallon ground level storage tank with a booster pump station would also be 

required. The tank would be constructed in accordance with applicable AWWA standards. The 

tank size is based on a fire flow storage volume of 300,000 gallons (2500 gpm for 2 hours) and 

100,000 gallons of operational storage to help meet diurnal demands including peak hour 

demands on maximum demand days. The final treatment plant size, tank size and booster pump 

station capacity would be dependent upon the actual well supply capacity, and size of the project 

(Alternative B or Alternative C). Each well, water treatment plant and pump station would need 

to have an on-site backup power generator. The pump station would need to be sized to meet the 

maximum day demand and fire flow with the largest pump out of service. Figure 2-1 presents a 

preliminary layout of the required facilities. Figures 1-5 and 1-6 show the possible location of 
Section 2 Water Supply 

Stantec Lytton Rancheria Feasibility Study

October 2010 2-5 AESS08-001

these facilities. Final layout and locations would be determined upon detailed site investigations 

as a part of the final design. 

As mentioned in the Hydrogeologic Investigation Report, included in Appendix A, the water 

quality of the groundwater generally meets applicable drinking water standards with the 

exception of arsenic and manganese. Therefore, the proposed water supply facilities include a 

small water treatment plant that will treat these two constituents and allow groundwater to meet 

current drinking water standards. The proposed layout assumes that raw water from each 

groundwater well will be conveyed directly to the water treatment plant, and the treatment plant 

capacity will be sized to treat the maximum day demand design flow at a minimum. 

Based on current experiences and proven technologies for the treatment of the two identified 

constituents, the small water treatment plant will consist of a coagulation/precipitation and 

filtration process. This process includes pH adjustment, oxidation with sodium hypochlorite, coprecipitation with ferric chloride, filtration/adsorption with a manganese dioxide filtration media, 

and a final pH adjustment for distribution. The treatment residuals will require a sludge 

thickening and disposal process. Figure 2-1 presents a preliminary layout of the water treatment 

plant based on the process being proposed.

It is estimated that the treatment process will consist of the following: 

Addition of sulfuric acid to reduce groundwater pH to 7.0 for optimum oxidation of 

the arsenic for the co-precipitation process. 

Oxidation of the raw water with Sodium Hypochlorite for conversion of any soluble 

iron and arsenic to the insoluble forms. 

Addition of a ferric based coagulant to optimize ferro-arsenate precipitation prior to 

filtration.

Micro-filtration with manganese dioxide filters to remove the ferro-arsenate 

precipitation from the water, and adsorb manganese from the water.. 

Periodic backwashing of filters, with backwash being conveyed to the backwash waste 

tank for disposal. 

pH re-adjustment with sodium hydroxide prior to conveyance to the potable water 

supply system. 

Water treatment residuals management is a major factor in any water treatment plant design. For 

arsenic treatment, wastes are typically settled solids, the by-products of chemical coagulation, 

plus iron and manganese precipitate captured during filtration. The backwash liquid may 

constitute 3 to 10 percent of the volume of raw water processed, and solids concentration may 

vary from 0.5 to 2 percent, depending on the raw water quality and volume processed. These 

residuals are classified as industrial wastes, and disposal into surface waters falls under the 

jurisdiction of the Federal Water Pollution Control Act Amendments of 1972 and the Clean 

Water Act of 1977. Given the unknowns at this time regarding disposal into the proposed on-site 

sewage system and associated effluent water quality impacts, for planning purposes it is proposed 

that residuals thickening will be included at the water treatment plant. The preliminary layout of 

the treatment plant includes a backwash settling tank to encourage settling of the solids and allow 

for recycling of the supernatant back to the front of the water treatment plant. Thickened solids 

would be transported to the wastewater treatment plant solids handling dewatering facility for 

dewatering and eventual offsite disposal at the regional landfill. 

It should be noted that the design for the water treatment plant outlined above and layout shown 

in Figure 2-1 are preliminary and will be refined during final design.

Wastewater Collection, Treatment, and 

Disposal

3.1 PURPOSE AND SCOPE 

The purpose of this section is to summarize the evaluation of wastewater treatment and disposal 

options for the Lytton Rancheria Project (Proposed Project). 

The remainder of this section is organized in following subsections: 

Wastewater Collection System Evaluation 

Wastewater Flows and Loads 

Treatment and Disposal Options 

Discharge to the Town of Windsor sewer system 

On-site treatment, storage and reclamation 

Surface Water Discharge 

Subsurface Disposal 

3.2 WASTEWATER COLLECTION SYSTEM EVALUATION 

Wastewater is conveyed in collection systems either by gravity or by pressure systems using 

pumps. Pressure collection systems require higher maintenance, oversight, and capital costs 

because of the number of pumps involved. Gravity collection systems minimize maintenance 

requirements, but are more inclined to experience inflow and infiltration of non-wastewater into 

the collection system. A gravity wastewater collection system has been selected for this project. 

3.3 WASTEWATER FLOWS AND LOADS 

3.3.1 WASTEWATER FLOWS

Estimates of wastewater flows from the proposed individual homes, retreat house, and 

community areas are discussed in Section 1 and shown in Table 1-3. 

These values are subject to revision during design if new information becomes available. The 

incremental increase in wastewater volume that reaches the WWTRF from I/I into the gravity 

collection system is estimated to be 15 percent of annual dry weather flow (ADWF) during 

typical rainfall years and 25 percent of ADWF during 100-year design rainfall conditions.

3.3.2 BOD, TSS, AND TKN CONCENTRATIONS

The Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS), and Total Kjeldahl 

Nitrogen (TKN) influent wastewater concentrations under 100-year rainfall conditions for the 

proposed development are estimated using typical literature values (Metcalf and Eddy, 2003),

3.4 WASTEWATER TREATMENT AND DISPOSAL OPTIONS 

Based on the wastewater flow and load projections listed in Table 3-2 and a gravity wastewater 

collection system, the following wastewater disposal options were evaluated: 

Option 1: Discharge to the Town of Windsor Sewer System 

Option 2: On-site Treatment, Storage, and Reclamation 

Option 3: Surface Water Discharge

Option 4: Subsurface Disposal 

The level of wastewater treatment is governed largely by the disposal option and corresponding 

regulations. Therefore, the required wastewater treatment process is discussed specific to each 
Section 3 Wastewater Collection, Treatment, and Disposal 

Stantec Lytton Rancheria Feasibility Study

October 2010 3-3 AESS08-001

disposal option. It is our understanding that the proposed project land is tribal land, and therefore 

is not subject to state or county laws or regulations. However, it is the intent of the project 

proponents to comply with state and county laws and regulations, to the extent feasible. 

3.5 OPTION 1: CONNECT TO THE TOWN OF WINDSOR SEWER 

SYSTEM

Under this option, wastewater from the proposed project would be conveyed to the Town of 

Windsor Wastewater Treatment, Reclamation and Disposal Facility (WWTRDF) through the 

Town’s existing municipal wastewater collection system. A sewage pump station and 

approximately 3,200 feet of force main would be constructed to convey the project’s wastewater 

to a manhole located near the intersection of Windsor River Road and Starr Road. The existing 

WWTRDF is believed to have sufficient treatment and disposal capacity to serve the proposed 

project.

Connecting the proposed project to the WWTRDF is the preferred alternative for this project. 

This is because it eliminates the creation of a small “stand alone” wastewater utility on the 

project site. 

3.6 OPTION 2: ON-SITE TREATMENT, STORAGE AND RECLAMATION 

3.6.1 DESCRIPTION

Under Option 2, wastewater would be conveyed to an on-site Wastewater Treatment Plant 

(WWTRF). Treated effluent will be utilized for irrigation of landscaping and crops (i.e., water 

reclamation) during dry periods and stored during wet periods when irrigation is not needed. 

3.6.2 REGULATIONS 

3.6.2.1 Water Reclamation Regulations 

The project proponents wish to comply with the intent of State regulations regarding reclamation 

of wastewater. These regulations are described in Chapter 3, Division 4, Title 22, California 

Code of Regulations (CCR), Section 60304, et seq. (Title 22). There are currently no specific 

Federal regulations pertaining to water reclamation on tribal lands. 

Effluent from the WWTRF would be reused for on-site irrigation to varying degrees under 

Alternatives B1, B2, and C. Because effluent irrigation of parks and play areas is involved with 

these alternatives, tertiary treatment of the wastewater is appropriate under Title 22. A 

description of Title 22 tertiary effluent and its appropriate uses is presented in Table 3-3.

3.6.2.2 Odor Control 

Odor control will be required to help mitigate the potential for foul odors being released from the 

wastewater treatment plant. In general, foul odors can be generated from the raw wastewater 

entering the headworks of the treatment facility. A certain amount of the foul smell can be 

mitigated by covering open channels at the headworks but it is usually not sufficient. Therefore, 

the wastewater treatment plant is proposed to be constructed with an active odor control system 

similar to that used at many other newer wastewater treatment facilities. 

Based on the preliminary design of the wastewater treatment plant, the proposed active odor 

control system will consist of a packaged biofilter with activated carbon adsorption unit. In 

general, the odor control system will vacuum air off the headworks and blow it through the 

biofilter and carbon adsorption unit before exhausting the treated air to the atmosphere. The 

biofilter treats the air stream by two simultaneous processes: sorption and bioconversion. 

Naturally occurring microorganisms exist on the biofilter media surface (woodchips, compost, 

etc.) that degrade the odorous compounds. Exhaust air is then conveyed to the carbon adsorption 

unit where chemical and physical adsorption to the activated carbon removes additional odors 

from the air stream. 

The result of the odor control system is the minimal release of foul odors from the treatment 

plant. Consequently, the potential for significant odors originating from the WWTRF should be 

less than significant.

3.6.3 TERTIARY TREATMENT PROCESSES

Several tertiary treatment technologies exist. For this specific WWTRF tertiary membrane 

bioreactor (MBR) treatment is recommended. This is because MBRs do not use a settling 

process which can be sensitive to several wastewater and operational parameters. Therefore, 

MBRs are a more robust treatment process. MBRs also produce effluent turbidities an order of 

magnitude lower than traditional sand filter tertiary treatment processes. MBRs are an 

established technology for wastewater treatment. Effluent disinfection using ultraviolet (UV) 

light is recommended with MBR treatment because it is reliable and has fewer secondary adverse 

impacts on the environment compared to chlorine. 

Approximately one acre will be required for the WWTRF. Planned WWTRF features include: 

flow measurement, influent pumping, fine screening, influent flow equalization and emergency 

storage, secondary and tertiary treatment with MBRs, UV disinfection, effluent pumping, solids 

handling facilities, and onsite stormwater detention. 

The main features of the different processes, supporting systems, and associated infrastructure to 

be included in the WWTRF are discussed in the following sections. A preliminary WWTRF 

layout is provided in Figure 3-1. 
Section 3 Wastewater Collection, Treatment, and Disposal 

Stantec Lytton Rancheria Feasibility Study

October 2010 3-6 AESS08-001

Figure 3-1

Wastewater Treatment and Reclamation Facility Preliminary Layout 

3.6.3.1 Headworks 

An automatic rotary drum screen or band screen is recommended to remove particulate material 

larger than 2 millimeters from the incoming raw wastewater. 

1. Rotary Drum Screen: In the rotary drum screen system, the wastewater enters the 

rotary drum screen through an inlet pipe where it is fed to the inside of the drum. The 

liquid filtrate passes through the drum screen into a collection trough, leaving the 

screenings on the inside of the drum. Rotary drum screens contain an internal screw 

that transports screenings out of the drum to the screw compactor for washing and 

dewatering. The washed and compacted screenings are discharged into a chute for 

offsite disposal. The screenings will likely be trucked offsite to an appropriate landfill 

on a weekly basis. 

2. Band Screen: Ban screen systems consist of a continuous loop of stainless steel 

screen moving like a conveyor belt. As the flow passes through the stainless steel 

screen, solids are captured and conveyed up and out of the flow to the screen cleaning 

apparatus. The majority of the screenings are removed by the action of a spray 

washer. Any remaining screenings are removed by a rotating brush assembly. The 
Section 3 Wastewater Collection, Treatment, and Disposal 

Stantec Lytton Rancheria Feasibility Study

October 2010 3-7 AESS08-001

removed screenings are deposited into a washer/compactor and ultimately discharged 

for offsite disposal. 

The two screening systems described will be evaluated during the project pre-design phase to 

determine which system is the best suited for the WWTRF. 

3.6.3.2 Influent Flow Equalization and Emergency Storage 

Flow equalization facilities will be included in the WWTRF to limit the magnitude of the 

wastewater inflows to the MBRs. This equalization provides a more consistent process 

performance and reduces the size of the MBR and downstream facilities. The equalization 

facilities will be designed to reduce the MBR influent flow from peak-hour flow to peak-day 

flow. The fraction of the WWTRF influent wastewater in excess of the design peak-day flow 

will be diverted to an equalization tank. The contents of this tank will be gradually returned to 

the headworks when the flows entering the WWTRF are lower than the design peak-day flow. 

The return discharge flowrate from the equalization tank will be adjusted, via a modulating valve, 

to maintain the headworks output below the desired flow. 

The required size of the equalization tank is dependent on the diurnal pattern of the influent flows 

to the WWTRF, which do not exist yet. Based on previous experience, it is estimated that the 

volume of the equalization tank should be 25 percent of the total volume of wastewater received 

during the design peak-day. 

Title 22 requires that Water Reclamation Facilities that produce recycled water meet various 

reliability requirements. Within the context of the WWTRF project, these reliability 

requirements include an emergency storage facility with a capacity to store untreated or partially 

treated wastewater for at least 24 hours and standby replacement equipment to be able to return 

the off-line treatment units back to service within 24 hours. 

3.6.3.3 Biological Treatment and Filtration 

Biological treatment and filtration of the screened flows from the influent pump station will be 

accomplished by means of MBRs. Incoming wastewater from the screening system and/or the 

equalization facility will be directed to the MBR splitter structure and distributed evenly to the 

available MBR reactors. The MBR effluent will flow to the disinfection system. 

An MBR unit combines an activated sludge process with membrane filtration for solids 

separation. Compared with traditional activated sludge processes with clarifiers relying on 

settling for solids separation, MBRs significantly reduce the system’s footprint and provide 

effluent with higher quality. The MBR system will provide nitrogen removal by means of an 

activated sludge nitrification/denitrification process.

3.6.3.4 UV Disinfection 

UV disinfection produces water that is pathogen free by transferring electromagnetic radiation 

through mercury lamps to the organisms present in the water. This process reduces the need to 

handle, transport, and store toxic or corrosive chemicals such as chlorine. 
Section 3 Wastewater Collection, Treatment, and Disposal 

Stantec Lytton Rancheria Feasibility Study

October 2010 3-8 AESS08-001

The components of an UV disinfection system include: an influent flow splitting channel, the 

UV reactors, an UV effluent collection channel, and the associated electrical control system. The 

control system automatically adjusts UV lamp intensity with the flow rate and effluent 

transmittance to ensure adequate UV dosage is applied to the effluent at all times. 

3.6.3.5 Supporting Systems 

In addition to the main components discussed above, various ancillary or support systems are 

also required. These systems include: 

 Chemical Storage and Feed Systems: Chemicals expected to be used include 

sodium hypochlorite for membrane cleaning and maintenance, and caustic soda for 

water alkalinity adjustment. All chemical storage tanks and pumps will be contained 

within a spill basin to contain any spill or leak. A truck loading area next to the basin 

will be constructed and will be connected to a drainage system to contain any potential 

spill or leak. The chemicals used in the WWTRF will be fed to the different processes 

by means of peristaltic pumps. 

 Plant Water Systems: It is recommended that the plant water systems include 

facilities to provide potable water and utility water. 

 Stormwater Detention: Stormwater from impervious surfaces on the WWTRF site 

that have a reasonable potential to have contaminants on them will be conveyed to the 

WWTRF site stormwater detention basin. This basin will gradually discharge its 

contents into the influent pump station wet well. This wastewater flow is part of the 

I/I flow volume discussed in Section 1. 

 Emergency Electrical Supply: A standby diesel generator will be used to provide 

backup power when the utility power system is down. The fuel tank that feeds the 

standby generator will be able to provide at least 24 hours of operation at 100 percent 

load. In the event of a power utility failure, the generator will automatically power the 

plant via an automatic transfer switch. 

3.6.3.6 Biosolids Handling and Stabilization Facilities 

A centrifuge or belt filter press will be installed on site to dewater waste solids from the MBRT 

to approximately 18 to 25 percent solids content. Dewatered biosolids will be hauled off-site 

(e.g., landfill) for ultimate disposal. 

3.6.4 EFFLUENT STORAGE FACILITIES 

The amount of effluent storage needed is heavily dependent on monthly irrigation needs and 

precipitation under worst-case design conditions. The worst-case design condition is typically 

100-year rainfall amounts with that rain occurring over many months, and extending well into 

spring. Maximum spring rainfall records for the area were used in the analyses. A summary of 

effluent storage requirements resulting from these estimates is presented in Table 3-4.

1.01 Mgal storage requirements for Alternative B1 may be achieved using a closed steel tank (to 

avoid accumulation of 100-year rainfall in the tank). The larger effluent storage volumes needed 

with Alternatives B2 and C require open-topped, earthen reservoirs which will accumulate 100-

year rainfall (which is already reflected in the required storage volumes shown in Table 3-4). For 

these earthen reservoirs, the maximum slope of pond embankments will be 2.5:1 (horizontal to 

vertical). A minimum vertical distance of two feet of freeboard will be maintained between the 

design high water level and pond levee crowns. The reservoir(s) will be fenced and gated for 

vehicular access. The reservoir(s) will be lined using 60 mil high density polyethylene (HDPE) 

liner, to prevent effluent percolation from the reservoir that could cause effluent “springs” to 

occur in the vicinity of the reservoir. The reservoir(s) will also be equipped with draining 

systems and level monitors. Reconnaissance estimates of land needs for the various reservoir 

alternatives are presented in Table 3-5. These estimates are subject to change once site-specific 

information on soils, slopes, stability, and hydrogeology become available.

An effluent pump station will be located within the WWTRF site and will pump effluent (and 

when needed, supplemental irrigation water) to the reservoir. With Alternative B1, this pump 

station will also include the irrigation pumps. For Alternatives B2 and C, irrigation pumps will 

be at the WWTRF site as well as at the reservoir(s). 

3.6.5 RECLAMATION

Alternatives B1, B2, and C all require varying amounts of land to dispose of the effluent 

generated by these alternatives under varying climatic conditions, as shown in Table 3-6, with 

supporting water balances being presented as Tables 3-6A through 3-6F. The greatest amount of 

effluent reclamation land is needed under high rainfall conditions occurring well into spring. The 

water balance was developed to forecast effluent irrigation land needs based on 100-year rainfall 

amounts distributed such that maximum historical spring rainfall occurs. 

3.6.5.1 Supporting Calculations 

Criteria, assumptions, and notes related to calculation of effluent storage volumes and irrigation 

land requirements are discussed below. 

Notes that are applicable to Alternatives B1, B2, and C 

Rainfall Data: Synthesized 100-year rainfall data utilized in the calculations is 

developed based on RP100 data (55 inches) for the Windsor area published by CIMIS. 
Section 3 Wastewater Collection, Treatment, and Disposal 

Stantec Lytton Rancheria Feasibility Study

October 2010 3-11 AESS08-001

These 55 inches of rainfall are distributed monthly with rainfall occurring 

disproportionately in the months by allocating higher to irrigation transition months 

(such as April, May, September, October, and November). This approach provides a 

robust analysis with respect to effluent storage and irrigation land requirements. 

ETo Data: Evapotranspiration (ETo) data utilized in the calculations is obtained by 

averaging 19-year Windsor clipped grass ETo data published by CIMIS. 

Irrigation Need: Monthly irrigation need is based on ETo that is not satisfied by rainfall 

that is available to crops. ETo, unsatisfied, is calculated by subtracting monthly rainfall 

that is available to crops (total rainfall minus runoff) from monthly ETo. Monthly 

irrigation need is calculated by adjusting ETo, unsatisfied, based on irrigation efficiency 

of 80 percent. For reclamation on landscaping, the clipped grass ETo and 80 percent 

irrigation efficiency are appropriate. 1” Soil deficit was included in May of every year 

to allow the soil to drain and dry somewhat before the irrigation begins. Effluent 

reclamation on pasture grass fodder crops is expected to have a somewhat lower ET, 

and a somewhat lower irrigation efficiency than landscaping. The net effect is that 

pasture grass irrigation is expected to require essentially the same amount of irrigation 

water as landscaping on a per acre basis. Accordingly, a model based on high 

efficiency landscape irrigation also describes lower efficiency irrigation of fodder 

crops, or any mix of landscape and pasture irrigation acreages. 

Notes that are applicable to Alternative B1 

Storage in Irrigation Transition Months: Since effluent generated in Alternative B1 will 

be discharged to surface water when it is allowed (all year except from May 16 to 

September 30) and when not needed for irrigation, the conditions that control effluent 

storage occur either during the latter half of May in wet springs or during wet 

Septembers. Maximum storage requirements occur when high rainfall occurs in these 

months as reported in the calculation. Alternative B1 storage is provided by a covered 

storage tank. 

Effluent Stored in Irrigation Transition Months: Effluent stored during the start of the 

irrigation season will be utilized for irrigation in the following months of June and July. 

Effluent stored during the end of irrigation season (September) will be retreated and 

discharged to surface water after September 30 (or when it is allowed), if further 

irrigation is not needed in autumn. 

Notes that are applicable to Alternatives B2 and C 

Monthly Precipitation in Storage Basin: Synthesized 100-year rainfall data were used to 

estimate the amount of monthly effluent and rainfall collected in the effluent storage 

basin, based on a basin catch area(s). 

Monthly Evaporation in Storage Basin: Monthly evaporation from the surface of the 

storage basin is estimated to be 70 percent of ETo data. A portion (80%) of storage 

basin surface area is utilized in estimating loss of water due to evaporation from the 

storage basin. 

Effluent Storage Including Net Rainfall Collected or Evaporated: Ultimate storage 

volume is calculated based on the worst case cumulative storage volume required from 

September through winter to June using 100-Year synthesized rainfall data. 
Section 3 Wastewater Collection, Treatment, and Disposal 

Stantec Lytton Rancheria Feasibility Study

October 2010 3-12 AESS08-001

Components that are included in calculating the cumulative storage volume 

include: 1) monthly effluent generation, 2) monthly 100-year rainfall and 3) monthly 

evaporation.

Irrigation Land Required for the Worst-Case Scenario: The effluent irrigation land 

requirement is estimated based on worst case rainfall amounts, rainfall patterns, and 

effluent volumes. Sufficient land is provided to dispose of this maximum volume of 

water under shortest irrigation season conditions. Therefore, during years with average 

rainfall, the amount of irrigation land required will be much lower. To accommodate 

the dynamics of effluent volume, effluent storage, rainfall, and irrigation season, the 

effluent irrigation plan calls for effluent irrigation of landscaping areas first. The 

pasture lands will receive effluent only to the extent that is available from year-to-year. 

To maintain the pasture lands, well water may be used to supplement the effluent 

irrigation water supply.

3.6.6 EFFLUENT QUALITY AND CROSS CONNECTION CONTROL

A state-of-the-art MBR treatment process will provide Title 22 tertiary treatment to wastewater 

produced by the proposed project. Tertiary effluent leaving an MBR process has the appearance 

of potable water. 

The high quality of tertiary effluent increases the possibility of a tertiary effluent pipeline with its 

high quality water being confused with a potable water supply pipeline being mistaken for a 

potable water pipeline. This mistake can result in the tertiary effluent pipeline being connected 

to a potable water pipeline, a condition termed a “cross connection”. To control the possibility of 

cross connections, effluent will be conveyed in special purple pipe (or pipe wrapped in purple 

plastic) as required by Title 22. The purple pipe’s color is the industry standard warning that the 

pipe contains effluent, not potable water.

The actual chemical numeric quality of the effluent will not be known until the project is built 

and occupied. The mineralogical and chemical composition of the effluent will depend primarily 

on 1) the mineral and chemical makeup of the potable water supply, 2) the types of potable water 

supply piping used, and 3) the mineral and chemical use practices of future residents. As a 

general rule, tertiary effluent quality has been satisfactory for typical irrigation uses. 

3.6.7 EXPECTED NITROGEN AND SALINITY IMPACTS TO GROUNDWATER FROM RECLAMATION

Any agricultural or landscaping activity involving irrigation and/or fertilizers has the potential to 

have some impact on underlying groundwater quality regardless of whether effluent, potable 

water, groundwater, or river water is used as the irrigation water supply. Based on groundwater 

impacts caused by irrigated agriculture, the constituents of greatest concern are generally 

nitrogen and salinity. Because groundwater impacts are a long-term phenomenon, the project 

water balances for average rainfall conditions are the appropriate bases for these groundwater 

impact assessments. 

3.6.7.1 Nitrogen Balance 

The proposed WWTRF includes a nitrogen reduction process. Consequently, the average total 

nitrogen concentration in effluent is not expected to exceed 10 milligrams per liter (mg/L). 

Based on Table 3-4, under typical (i.e., average rainfall) conditions, Alternatives B1, B2 and C 

entail applying 11.6 Mgal, 27.3 Mgal, and 10.9 Mgal, respectively of effluent to 11 acres, 25.9 

acres, and 10.4 acres of vegetated land, respectively. This would result in a nitrogen application 

rate not exceeding 88 pounds per acre per year (lbs/ac/year). A typical nitrogen fertilization rate 

for turf grass (with some trees and shrubs) and fodder crops is about 200 to 300 lbs/ac/year. The 

nitrogen fertilizer value of the effluent will have to be supplemented with commercial nitrogen 

fertilizer for the landscaping being planned and to maximize fodder crop production. 

Consequently, effluent nitrogen concentrations should not be an issue with regard to degradation 

of underlying groundwater. Any degradation of underlying groundwater from nitrogen will be a 

result of the overlying land use (irrigated land) and not a result of effluent being used as the 

irrigation water supply for that overlying land use.

3.6.7.2 Salinity Impacts 

Preliminary estimates of salinity for a potable water supply using on-site wells, and the resulting 

effluent being reclaimed are summarized in Table 3-7. The typical salinity concentration of 

reclaimed water from the WWTRF (as applied to the land including effects of rainfall and I/I 

dilution) is estimated to be about 468 mg/L total dissolved solids (TDS), or approximately 

783 mhos/cm on an electrical conductivity (EC) basis.

(b) ECO:LOGIC Engineering, Hydrogeologic Investigation Report, 2009. 

(c) Town of Windsor Water Quality Comparison Report, 2008. 

The effects on effluent salinity of I/I, rainfall into storage, and evaporation from storage have 

been accounted for in the Table 3-7 estimates. It is noteworthy that TDS is not a good measure 

of actual salinity in effluents. This is because effluent contains many dissolved solids that are not 

salts. The mineral salinity of this effluent (as measures by the fixed dissolved solids test) is 

estimated to be around 430 mg/L. 

Estimated “salt balances” for the effluent reclamation aspects of the 124-acre project site under 

the predevelopment and Alternatives B1, B2, and C are presented in Figures 3-2, 3-3, 3-4, and 

3-5, respectively. As shown, the estimated salinity of overall site percolate to groundwater from 

rainfall, soil dissolution, and effluent reclamation is summarized in Table 3-8.

These salt balances and resulting percolate salinity estimates are based on 1) an effluent TDS of 

468 mg/L, ( as if all effluent TDS is salinity) 2) average rainfall and ETo conditions for the 

Windsor area, 3) a native oak woodland ETo of 16”/year, 4) an average rainfall runoff coefficient 

of 0.20, 5) no net salt uptake and removal by vegetation (to be conservative), 6) soil dissolution 

rates of 200 lb/Mgal in surface soils (i.e., within the root zone) and 600 lb/Mgal in deeper soil for 

water percolating to groundwater, and 7) stormwater leaving the effluent reclamation area having 

a TDS of 150 mg/L (compared to 34 mg/L for areas without salt addition from effluent). 

Regarding anti-degradation, means to reduce effluent salinity and/or percolate salinity include: 

Reduce effluent salinity by installing reverse osmosis (RO) treatment. RO treatment 

has not been shown to be a cost effective mitigation measure for small WWTRFs such 

as the one proposed for the project, or used by Windsor. 

Reduce water conservation measures in homes. This does not change the mass of salt 

involved, but reduces its concentration. Reducing water conservation is contrary to 

State policy, and therefore, is not recommended. 

Reduce use of products in the home: food, shampoo, cleaners, etc. This is a lifestyle 

issue that is virtually impossible to police in the project, or in Windsor. Public 

education can raise public awareness of salt issues, but may not affect lifestyle and 

resulting effluent salinity. 

Reduce effluent irrigation efficiency so that a lower percentage of applied effluent is 

evapotranspirated to the atmosphere. This practice leaves more water with the residual 

effluent salt mass, and thereby reduces the salinity of the percolate. Reducing 

irrigation efficacy is possible, but runs contrary to State water conservation policy, and 

therefore, is not recommended as an anti-degradation measure. 

Increase effluent discharges to surface waters, i.e., implement alternative A (preferred) 

or B1. 

The proposed project appears to include a reasonable balance of environmental and water 

resource preservation measures: 

Water conserving fixtures are proposed to reduce water use, but not to an extreme 

extent causing very high contaminant concentrations in the wastewater. 

Effluent reclamation to the extent feasible is proposed to reduce effluent discharges to 

surface waters, and to conserve freshwater for higher or better uses. 

High efficiency irrigation is proposed to maximize beneficial use of available water 

resources.

Community education is proposed to reduce needless introduction of contaminants to 

the wastewater. 

These project components appear to satisfy the requirements of State Board Resolution 68-16, 

the State’s Anti-Degradation Policy.

3.6.8 DISCUSSION

Based on the results summarized in Tables 3-4 through 3-8, the option of on-site treatment, 

storage and reclamation as part of Alternatives B1, B2, or C appears to be feasible. Reusing 

treated wastewater irrigation reduces use of the groundwater resources.

3.7 OPTION 3: SURFACE WATER DISCHARGE 

3.7.1 DESCRIPTION

With Option 3, treated effluent that could not be reclaimed feasibly would be discharged to one 

of the surface water drainage courses located on the property in the 1 October through 15 May 

period (per the Basin Plan restrictions of the Regional Water Board). Drainage patterns and 

representative photos of the drainage courses are shown in Figures 3-6, 3-7, and 3-8.

3.7.2 REGULATORY BASIS 

It is our understanding that any surface water discharge of effluent would be subject to federal 

law (specifically, the Clean Water Act (CWA) governing effluent discharges to surface waters). 

Section 301(a) of CWA provides that the discharge of any pollutant to waters of the United 

States is unlawful except in accordance with a National Pollutant Discharge Elimination System 

(NPDES) permit. The program is designed to limit the discharge of pollutants into waters of the 

U.S. from point sources (40 CFR 122.1 [b][1]) through a combination of various requirements 

including technology-based and water quality-based effluent limits. 

A partial list of potentially regulated pollutants is shown in Table 3-9. 

Table 3-9 

List of Potentially Regulated Pollutants 

Constituents

Ammonia Total Coliform Bacteria 

BOD TSS 

Nitrate Carcinogens 

Heavy metals Oil and Grease 

pH Whole Effluent Toxicity 

The Regional Water Board’s Basin Plan prohibits the discharge of effluent to the Russian River 

and its tributaries 1) during the period May 15 through September 30, and limits the amount of 

effluent discharged to 1 percent of the receiving water’s flow unless specific effluent discharge 

conditions are met (as specified in the Basin Plan). The proposed drainage courses to which the 

effluent would be discharged have relatively little flow except during and following precipitation 

events. Therefore, under effluent disposal Option 3, specific conditions of the Basin Plan 

allowing greater effluent percentages in these drainage courses should be met. 

3.7.3 TREATMENT REQUIREMENTS

The level of wastewater treatment needed with this disposal option is nitrification/denitrification 

activated sludge in the form of a membrane bioreactor (MBR) with UV disinfection, possibly 

enhanced with ozone. Descriptions of the aforementioned treatment facilities can be found in 

Section 3.6.3. 

3.7.4 PROPOSED SURFACE WATERS FOR RECEIVING EFFLUENT

Two surface water drainage courses have been identified by the project proponents: 1) an 

unnamed drainage course (Drainage Course 1) along the west of the property tributary to the 

Russian River flood plain, and 2) an unnamed drainage course (Drainage Course 2) along the east 

of the property tributary to Windsor Creek. These drainage courses and associated downstream 

waters are shown in Figure 3-1.
Section 4 Summary and Recommendations 

Stantec Lytton Rancheria Feasibility Study

October 2010 3-32 AESS08-001

3.7.4.1 Drainage Course 1 

Drainage Course 1 is an unnamed ephemeral drainage course located on the west side of the 

project property. It flows to the historical flood plain of the Russian River. Currently, its 

connection to the Russian River is blocked by a privately owned, abandoned, aggregate mining 

pond/pit located along the eastern bank of the Russian River. The pond’s water level reportedly 

fluctuates with the water level in the river, i.e., they are connected hydraulically. 

3.7.4.2 Drainage Course 2 

Drainage Course 2 connects to Windsor Creek along the east of the property. Windsor Creek 

connects to Mark West Creek, which connects to the Russian River. 

3.8 DISPOSAL OPTION 4: SUBSURFACE DISPOSAL 

3.8.1 DESCRIPTION

Typically, subsurface disposal systems consist of rock-filled trenches or beds that distribute the 

effluent for absorption into the surrounding soil. A perforated pipe and possibly dosing 

apparatus facilitate effluent distribution throughout the rock-filled trench system. Other types of 

subsurface disposal systems may be used as alternatives, and are referred as non-standard 

systems. The feasibility of Subsurface Disposal systems is heavily dependent on the soil type, 

soil depth, groundwater depth, precipitation, and hydrogeological conditions. With subsurface 

disposal, the critical issue is not so much as to whether the soil will absorb the effluent, but rather 

are hydrogeologic conditions such that once absorbed the effluent will move away from the 

absorption area so that more effluent can be absorbed day-by-day without the effluent surfacing 

out of the ground. 

Non-standard subsurface disposal systems are considered for this evaluation. This is because the 

United States Department of Agriculture (USDA) National Cooperative Soil Survey indicates 

that the soil types found at the proposed project site have limited absorption capabilities 

(USDA, 2008). This is not unusual because over 90 percent of land in Sonoma County has been 

found to be unsuitable for a typical subsurface disposal system (Sonoma County, 2007). 

3.8.2 REGULATIONS AND TREATMENT REQUIREMENTS

The project proponents propose to treat the wastewater to high level before subsurface disposal, 

and comply with Federal regulations regarding subsurface disposal of highly treated municipal 

effluent. Sonoma County non-standard disposal systems guidelines are not applicable to this 

project as the guidelines were developed for the subsurface disposal of on-site septic tank 

effluent.

3.8.3 ASSESSMENT OF SUBSURFACE DISPOSAL FEASIBILITY

Before subsurface disposal systems (e.g., leachfields) could be designed for the site and the 

capacity of those leachfields accurately estimated, site-specific soil percolation data would need

to be obtained. Therefore, it is currently unknown if sufficient leachfield capacity could be 

developed on the site.

Section 4 

Summary and Conclusions 

4.1 WATER SUPPLY DEMAND AND WASTEWATER FLOWS 

The potable water demand for Alternatives A, B1, B2, and C (as described in Section 1) are 

estimated at an average daily flow of 82,300, 82,300, 82,300 and 31,700 gallons per day (gpd), 

respectively (see Table 1-1), assuming potable water is used to irrigate landscaping around the 

homes. If effluent is used for some to all residential landscaping, then potable water needs would 

be less. If on-site well water is used for all residential landscaping, then Alternative A potable 

water needs from the Town of Windsor would be reduced. 

Wastewater flows are directly dependent on the number of housing units and communal facilities 

provided. The estimated peak daily wastewater flow for Alternatives A, B1, B2, and C are 

64,000, 64,000, 64,000, and 25,000 gpd, respectively (see Table 1-3), excluding I/I effects. 

4.2 WATER SUPPLY 

Two water supply options were evaluated. 

4.2.1 CONNECT TO THE TOWN OF WINDSOR POTABLE WATER SYSTEM

The proposed project could receive potable water service from the Town of Windsor municipal 

potable water system by connecting to the existing 18-inch diameter water main located 

immediately north of the property. This option has less risk of upset than a small on-site water 

utility, and accordingly is the preferred option for this project. This is the recommendation 

regardless of whether the Town of Windsor can provide wastewater service to the project 

(Alternative A).

4.2.2 ON-SITE POTABLE WATER SUPPLY

An on-site potable water supply system would consist of at least two groundwater production 

wells. The wells would be capable of meeting the maximum day demand with the largest well 

out of service. Storage will be used to meet maximum diurnal water demands within the 

maximum use day. A hydrogeologic evaluation and field investigation was completed (see 

Appendix A). The conclusion of this investigation is that the estimated water-supply demands 

for the project can be met with on-site wells. Water quality sampling from the test well indicates 

that treatment will be required to remove arsenic and manganese to meet California and Federal 

Drinking Water Standards. Therefore, water from the individual wells would be conveyed to an 

on-site water treatment facility to reduce arsenic and manganese concentrations to current 

drinking water standards. The water treatment facility will be sized to treat the maximum day 

demand design flow. The treated water will be pumped to convey this water to the ground level

water storage tank. Since the wells will not meet the estimated required fire flow of 2,500 gpm, a 

400,000 gallon ground level storage tank with booster pump station will be provided to meet this 

community safety need. 

4.3 WASTEWATER COLLECTION, TREATMENT AND DISPOSAL

Four wastewater treatment and disposal alternatives were evaluated. 

4.3.1 ALTERNATIVE A: CONNECTION TO THE TOWN OF WINDSOR SEWER SYSTEM 

Under this alternative, raw wastewater from a proposed project of 147 residences would be 

conveyed to the Town of Windsor Wastewater Treatment, Reclamation and Disposal Facility 

(WWTRDF) via the municipal sewer collection system. To facilitate this, a sewage pump station 

and approximately 3,200 feet of force main would be constructed to convey the wastewater from 

the project to a manhole located near the intersection of Windsor River Road and Starr Road. 

Connecting the proposed project to the municipal sewer system is the preferred alternative for 

this project. This is because larger wastewater treatment plants tend to be more reliable than 

smaller plants for several reasons including 1) influent wastewater characteristics are less 

variable typically, 2) plant staffing is greater and often more specialized, and 3) reliability 

features are more cost effectively included in larger plants. 

4.3.2 ALTERNATIVE B1: SEASONAL EFFLUENT DISCHARGES TO SURFACE WATER

With Alternative B1, the service area includes 147 residences. Wastewater from this project 

would be treated on-site to Title 22 tertiary recycled water standards. Treatment would be 

provided by a flow equalized, nitrification/denitrification, MBR process, followed by UV 

disinfection. This type of treatment process is believed to maximize effluent quality and 

reliability. 

In dry weather, tertiary effluent will be used to irrigate landscaping and/or pasture areas to the 

extent feasible. Effluent that cannot be reclaimed will be discharged to surface waters to the 

extent feasible. Effluent that cannot be discharged or reclaimed for any reason will be stored 

until it can be disposed in one of these manners. 

Two drainage courses have been identified by the project proponents as being suitable for 

receiving tertiary treated wastewater. Drainage Course 1 is an ephemeral drainage course located 

west of the project site. This stream flows to a nearby abandoned gravel pit that is connected to 

the Russian River. Drainage Course 2 is an ephemeral unnamed tributary to Windsor Creek east 

of the property. Windsor Creek connects to Mark West Creek, which connects to the Russian 

River. Effluent discharges to one or both streams would occur in winter/spring, under 

Alternative B1. 

Effluent discharges to the Russian River and its tributaries are subject to Federal Law (i.e., the 

Clean Water Act governing effluent discharges to surface waters). The Regional Water Board’s 
Section 4 Summary and Recommendations

Basin Plan also limits when effluent can be discharged to these surface waters and in amounts 

(i.e., there are dilution requirements). The Basin Plan provides means to adjust some of these 

limitations if certain conditions are met. 

4.3.3 ALTERNATIVE B2: YEAR-ROUND RECLAMATION OF EFFLUENT FROM 147 RESIDENTIAL 

UNITS

Alternative B2 is identical to Alternative B1, except that effluent discharged to surface waters 

under B1 would be stored for subsequent reclamation during the following summer under B2. 

To accomplish this requires Alternative B2 to have storage reservoirs (with estimated capacity of 

23.49 Mgal) capable of holding all effluent and rainfall occurring under 100-year rainfall 

conditions. Reclaiming this stored effluent and rainfall plus the dry season effluent requires 

estimated 42.1 acres of reclamation area. 

4.3.4 ALTERNATIVE C: YEAR-ROUND RECLAMATION OF EFFLUENT FROM 55 RESIDENTIAL 

UNITS

Alternative C is identical to alternative B2, except that the service level is reduced from 147 

residential units to 55 residential units. This change reduces the amount of effluent produced, 

and therefore the volume of winter/spring effluent storage needed, and the area of effluent 

reclamation land needed. Rough estimates of the storage volume and land area needs are 10.27 

Mgal and 17.6 acres, respectively.

1.0 SUMMARY AND CONCLUSIONS 

1. The Lytton Band of the Pomo Indians proposes to develop a residential community on 

approximately 124 acres of land located on fourteen contiguous parcels about one mile west 

of Windsor, California. Three development alternatives are being considered. Alternative B, 

which includes 147 residences and other facilities, would have an average water demand of 

57 gallons per minute (gpm). Initially, it was uncertain if on-site wells could meet this 

requirement, and, if so, how groundwater production would affect nearby residential wells. 

2. A preliminary feasibility study and literature review concluded that the local aquifer was of 

variable productivity, but that there was a reasonable chance that the water-supply could be 

developed from on-site wells. A residential well was located on one of the property’s parcels 

at 1800 Windsor River Road. No information was available on its construction or geology. 

A brief pumping test performed in October 2008 produced 43 gpm with less than nine feet of 

drawdown. The well is of limited value because it produced excessive sand, but the results 

indicated that a moderately transmissive aquifer existed at the locale, and that sufficient 

groundwater resources could be present to supply Alternative B water requirements. An 

exploratory well drilling and testing program was recommended to acquire more detailed, 

site-specific hydrogeologic data. 

3. A test well and a dual-completion monitoring well were drilled on the parcel by Vannucci

Technologies using mud-rotary drilling equipment. The new wells were located about 75 

feet apart near the top of a ridge that is about 190 feet north of the existing residential well. 

All permits relating to well construction were obtained by Vannucci Technologies. 

4. The test well pilot hole was drilled to a depth of 500 ft below ground surface (bgs). The 

borehole penetrated oxidized unconsolidated sand, gravel and lesser clay to a depth of 

about 115 feet. Beneath this upper unit, weakly-indurated, sandy, silty clay (called 

mudstone for the purposes of this report) was present to the bottom of the hole. Several 

coarse-grained, permeable sand and gravel horizons were interspersed in the mudstone. 

Borehole geophysical logs were acquired and used in conjunction with the lithologic data to 

design the well. The well was reamed to a depth of 422 feet bgs and constructed with 6-

inch-diameter casing and well screen. The well screen was selectively placed below the 

upper oxidized zone from 141 to 201 feet, 221 to 261 feet, and from 301 to 421 feet bgs. 

5. The monitoring well pilot hole was drilled to 438 feet bgs. The subsurface geology 

encountered in the borehole was very similar to that found in the test well, with good 

correlation between distinct marker beds common to both wells. Borehole geophysical logs 

were acquired and used in conjunction with the lithologic data to design and construct two 

“nested”, 2-inch diameter PVC well casings in the one borehole. The shallow monitoring 

well was completed with well screen placed between 110 and 120 feet bgs specifically to 

monitor water levels within the upper oxidized sand and gravel unit that overlies the deeper 

strata tapped by the test well. The deep monitoring well was completed with screen 

intervals from 150 to 200 feet, 230 to 260 feet, and 310 to 420 feet bgs to be consistent with 

the test well. An intervening clay stratum separates water-bearing strata tapped by the two 

monitoring wells. A sand filter pack was placed in the annular space opposite the screen 

intervals and a bentonite annular seal was placed in the interval between the two wells to 

isolate the zones from each other. 

6. The wells were developed to remove residual drilling fluids and fine-grained formation 

materials. The shallow and deep monitoring wells were developed by air-lift pumping. 
Lytton Rancheria Project Hydrogeologic Investigation Report 

App A - Lytton Test Well Report Final 6 ALT 09-30-10 2 10/1/2010 

Development of the test well included air-lift pumping followed by pumping and surging 

using a submersible pump at rates of up to 275 gpm. Development procedures were 

terminated when discharge from each well cleared. 

7. Following well development, the static water levels were measured at about 99.5 feet bgs in 

the shallow monitoring well and 123.8 feet bgs in the deep monitoring well, indicating a 

downward vertical hydraulic gradient. The water level in the test well was 123.5 feet bgs, 

very similar to that in the deep monitoring well. At the existing residential well, which is 

present at a lower elevation than the new wells, the static water level was measured at 75.9 

ft bgs, which is similar to the piezometric level in the test well and deep monitoring wells. 

8. The testing program comprised a four-hour step-drawdown test and a 72-hour constantdischarge test. The step test discharge rates ranged from 121 to 272 gpm with drawdown 

ranging from 10 to 27 feet. Based on these results, and the anticipated water requirements, 

the constant-discharge test was conducted at an average pumping rate of 150.3 gpm. At 

the completion of the test, drawdown in the test well was measured at 25.7 feet. The deep 

monitoring well and the residential well responded to test well pumping, but the shallow 

monitoring well showed only minuscule variations in water levels. Drawdown at the end of 

the test was about 11.8 feet and 10.2 feet in the deep monitoring well and residential well, 

respectively. 

9. The aquifer transmissivity (the overall ability of the aquifer to transmit groundwater) was 

calculated to be approximately 2000 feet2

/day (15,000 gallons per day per foot width of 

aquifer at a unit hydraulic gradient (gpd/ft)). The coefficient of storage was calculated to be 

approximately 0.015, which is indicative of semi-confined to unconfined conditions. The 

analysis required the use of two discharge (no-flow) boundaries, which are likely fault 

surfaces. 

10. A groundwater sample was collected from the test well’s discharge near the conclusion of 

the pumping test and submitted to California-certified environmental laboratories for analysis 

of Title 22 parameters. The total dissolved solids (TDS) was 270 mg/L suggesting overall 

good water quality. However, concentrations of arsenic (0.058 mg/L) and manganese 

(0.015 mg/L) did not meet California and Federal Drinking Water Standards and treatment 

will be required. No other analyzed parameters exceeded water quality standards, but a 

faint hydrogen sulfide odor was occasionally noticed coming from the discharge during the 

pumping tests. 

11. The test results indicate an 80%-efficient production well at the test well site would be 

capable of continuous pumping 75 gpm for extended periods without excessive drawdown 

(even in the absence of recharge) and 150 gpm or more for shorter periods to meet peak 

demand. The amount of drawdown in the well is not considered excessive because it 

amounts to about 10% of the aquifer thickness and because average drawdown would be 

maintained above the top of the screen interval. At pumping rates greater than 150 gpm 

there is a potential for cascading water to occur if pumping levels are drawn down below the 

top of the perforations. 

12. The closest existing domestic well to the test well is located approximately 700 feet to the 

east. Potential interference drawdown in this well was calculated assuming it derives 

groundwater from the same strata as the test well, that there are no hydrologic boundaries 

present that would isolate the well from the test well site, and that there is no recharge to the 

aquifer. After continuously pumping a hypothetical production well for one year at a 

continuous rate of 57 gpm, interference drawdown at the nearest well was calculated to be 
Lytton Rancheria Project Hydrogeologic Investigation Report 

App A - Lytton Test Well Report Final 6 ALT 09-30-10 3 10/1/2010 

approximately 8.5 feet. If this offsite well derives water from shallower aquifer materials than 

the test well, less interference drawdown should be expected, on the order of three feet. At 

a distance of approximately 2,000 feet, drawdown was also calculated to be about three 

feet. Assuming an aquifer thickness of 300 feet based on the test well program, the 

calculated drawdown represents only 1 to 3% of available drawdown in the aquifer within 

this radius. Because some recharge to the aquifer occurs even during years of lower-thannormal precipitation, and area groundwater levels have been reported to be stable, the 

calculations are likely conservative and actual interference drawdown may be less. 

Consequently, estimated impacts to the overall aquifer as a result of the project are not 

considered significant. 

13. Recommended preliminary design criteria for a production well at this site include: 

a. Well depth: approximately 350 feet. 

b. Conductor casing: 24 inch diameter casing installed to a depth of 40 feet and grouted 

in place.

c. Production well borehole diameter: 18 inches (below the conductor casing). The 

production borehole should be drilled below the conductor casing using the reverse 

circulation drilling method. 

d. Well casing and screen diameter: 10 3⁄4-inch outside diameter. 

e. Casing material: Low carbon steel. 

f. Screen material: Type 316L stainless steel w/ dissimilar metal connector. 

g. Screen Slot aperture width: 0.035 inch. 

h. Screened interval: Approximately 145 to 185, 230 to 250, and 305 to 345 feet below 

land surface. The blank casing from 185 to 230 would provide a reasonable location 

for the pump intake.

i. Filter pack: Either Colorado Silica 8x20 or 8x16 mesh sand. 

The final design of the production well should be based on the data obtained through the 

drilling of the production well borehole.

2.0 INTRODUCTION 

The Lytton Band of Pomo Indians is in the process of planning a new community development 

about one mile west of the City of Windsor, California, on fourteen parcels that total 

approximately 124.12 acres (“Property”, see Figure 1). Three development alternatives are 

being considered. This report focuses on “Alternative B”, which includes 147 residences, a 

community center, a ceremonial roundhouse, parks and open space, and onsite water and 

wastewater facilities. This alternative would have an average daily water demand estimated at 

57 gallons per minute (ECO:LOGIC, 2009). The parcels are largely undeveloped, hilly, wooded 

land, but include several existing residences (see Figure 2). Water is supplied to these parcels 

from either residential wells or a Town of Windsor municipal well located west of Eastside Road. 

On behalf of the Lytton Tribe, Analytical Environmental Services, Inc., (AES) initially engaged 

ECO:LOGIC Engineering to undertake a planning-level evaluation of the groundwater resources 

potentially available to the project to determine whether there was a reasonable likelihood that 

Alternative B could be supplied by groundwater from wells on the Property. The evaluation also 

examined potential interference affects on nearby wells. 

As part of the initial investigation, ECO:LOGIC reviewed State of California well reports (well 

logs), published reports, and other available information. The investigation concluded that, 

although the local well yields were highly variable, it was possible, but not certain, that wells on 

the property could provide the necessary water supply. ECO:LOGIC recommended a 

comprehensive field investigation to evaluate the reliable long-term yield of well(s) at the 

property, as well as potential impacts on nearby wells (ECO:LOGIC, 2009). The recommended 

program included new test and monitoring wells, and an aquifer-stress test. The program was 

designed to provide confidence in the results and to be consistent with Sonoma County’s 

development guidelines. 

AES retained ECO:LOGIC to provide hydrogeologic consulting services for the program. 

Drilling and testing services were subcontracted to Vannucci Technologies. The main goals of 

the exploratory drilling and testing program were to: 

 Evaluate the local geology and the hydraulic properties of the aquifer materials. 

 Assess the potential yield of a production well at the site. 

 Assess the chemical quality of the groundwater. 

 Provide the design criteria for a subsequent production well(s), if site-specific aquifer 

characteristics were favorable. 

During a site inspection on October 16, 2008, a residential well was found on the parcel located 

at 1800 Windsor River Road (see Figure 3). At the time, this was the only well located on the 

Property, which has since been expanded to the east. To obtain a site-specific estimate of 

possible production-well yield, ECO:LOGIC performed a brief pumping test on this well on 

October 21, 2008. The pump discharged a maximum of 43 gallons per minute with 8.8 feet of 

drawdown, exceeding our expectations based on the results of the preliminary investigation. 

Because the parcel was located outside of the Russian River plain and portions were easily 

accessible by drilling equipment, the test and monitoring wells were installed, developed and 

test pumped at this site. This report documents the drilling and testing program and our 

conclusions.

3.0 HYDROGEOLOGIC SETTING 

3.1 Topography 

The Lytton property is situated within the Santa Rosa Plain Subbasin (Groundwater Basin 

Number 1-55.01) of the Santa Rosa Valley, less than one mile east of the Russian River, and 

very near the boundary with the Healdsburg Area Subbasin (see Figure 4). The area of the 

Santa Rosa Plain is approximately 125 square miles. Precipitation ranges between 20 inches 

per year in the south and 40 inches per year in the north (DWR, 2003). Large ponds exist in the 

Russian River flood plain between the river and the Property (see Figure 1) that formed in 

former aggregate mines that were excavated below the water table. 

Elevations at the Property range from about 100 feet above mean sea level (amsl) to about 210 

feet amsl. A north-south trending drainage divide essentially bisects the property (Figure 5). 

Most of the property drains westward towards the Russian River. East of the divide, surface 

water runoff contributes to Windsor Creek, a tributary to Mark West Creek, which flows to 

Laguna de Santa Rosa, which in turn, flows to the Russian River. The new well sites are 

located just west of the divide. 

3.2 Site Geology 

Ford (1975) described the area near-surface geology as early Quaternary, non-marine 

sediments comprised of clay, sand and minor gravel that belong to the Glen Ellen Formation 

(Ford, 1975). The Formation is described as: 

“. . . composed of an extremely heterogeneous mixture of pale buff clay, silt, sand 

and gravel....Many beds grade laterally from coarse gravels into clay. The coarse 

materials are usually of andesitic composition, although some obsidian is present. 

Particle size ranges up to 6 inches in diameter (ibid., page 157)....Much of the 

Glen Ellen overlies the Sonoma Volcanics with some degree of unconformity. At a 

few localities it is intercalated with volcanic materials belonging to the Sonoma 

Volcanics.” 

Younger alluvium or terrace deposits of unconsolidated sand and gravel overlie the Older 

Alluvial Fan deposits In the Russian River valley west of the Property. California’s Groundwater 

Bulletin 118, correlated the area aquifer with the Glen Ellen Formation. However, Blake (2002) 

reclassified the Glen Ellen formation in the Windsor and Property areas as “Older Alluvial Fan 

Deposits” based on three factors: 

1) the materials are much less deformed than Glen Ellen Formation; 

2) they are not as lithified; and 

3) they lack the interbedded tuff that is widespread in much of the Glen Ellen 

Formation. 

The portion of Blake’s map that includes the Property area is provided in Figure 6. The 

Pleistocene, Older Alluvial Fan Deposits (Qpoaf) consist of: 

“Roughly horizontal beds of buff siltstone and claystone, buff to gray, fine- to

Glen Ellen Formation (QTge) based on similar clast composition (especially 

obsidian), we differentiate Qpoaf from QTge based on the lack of deformation 

and volcanics interbedded in Qpoaf and because Qpoaf is softer and less 

resistant than QTge. This unit is at least 65 m thick. It is incised and overlain by 

Qal.” 

As described below, the drilling program intersected materials consistent with this description, in 

that the sediments were weakly lithified, roughly horizontal, and lacked interbedded tuff. 

3.2.1 Structural Geology 

Blake’s geologic map of the area does not indicate any faults within the immediate Project area, 

but it seems plausible that some geologic structures might be present given the abundance of 

faults mapped in the area (see Figure 6). A northwest-trending valley with an ephemeral stream 

crosses the western side of the Property (see Figure 1). While this linear feature is not mapped 

as a fault, it is parallel to many regional faults, such as the northwest-trending Healdsburg fault 

zone. It is unknown whether or not this feature has any structural or hydrogeological 

significance. It is mentioned because faults of even limited displacement may act as boundaries 

to groundwater flow because they can displace low-permeability materials against permeable 

strata, or create a low-permeability smear zone in geologic materials with appreciable amounts 

of clay. If present, faults can affect long-term performance of wells on the Property or limit the 

potential interference with off-site wells. As described in Section 6.0, two discharge boundaries 

were suggested by the data from the constant-discharge pumping test. One of these 

boundaries might be explained by a fault in this drainage. 

3.3 Well Yields in the Glen Ellen Formation 

Well yields in the Glen Ellen Formation are highly variable because the formation is very 

heterogeneous (properties vary over small distances) and its permeability (ability to transmit 

water) is generally low (DWR, 2003). Wells completed in the Glen Ellen Formation typically 

yield one to 140 gpm with a specific capacity (a measure of well performance equal to the 

pumping rate divided by the drawdown, gpm/ft) of about two gpm/ft (DWR, 2003). 

Ford (1975) reported, ”the Glen Ellen Formation is highly variable in its water-yielding capability, 

even over short distances. In the Santa Rosa Plain area, wells tapping this formation generally 

yield adequate supplies for domestic use, stock watering, or limited irrigation. Specific 

capacities based on bailer tests range from 0.5 to 20 gpm per foot of drawdown” (ibid., page 

158). In the Windsor area, Ford reported that well yields ranged from 15 to 40 gpm, drawdowns 

were less than 50 feet, with depths to water usually being less than 100 feet. However, a 400-

foot-deep well in the Windsor area, although not in the immediate vicinity of the Property, 

produced upwards of 500 gpm with a specific capacity of 3.7 gpm/ft (ibid., page 159). 

The amount of water produced from a well constructed in the Glen Ellen Formation or the Older 

Alluvium depends on the geologic materials encountered at any given location and the well 

depth. Wells with low yields were either shallow, or drilled in areas that contain larger amounts 

of silt and clay, and fewer layers of clean, coarse sand and gravel. Additional information on 

Property-area well yields is provided in the following section.

3.4 Review Of Nearby Well Logs 

On behalf of the Bureau of Indian Affairs, ECO:LOGIC obtained copies of well logs from the 

California Department of Water Resources (CaDWR), Division of Planning and Local 

Assistance. The specific information contained in the logs is confidential. Consequently, only 

basic anonymous data for 20 nearby wells are provided in Table 1. A log was not provided for 

the Property’s residential well located at 1800 Windsor River Road, so recent test data are 

provided in the table. 

The logs generally reported relatively low yield and specific capacities based on short-term tests 

of uncertain precision. Because the tests were of relatively short duration and were performed 

by bailer or airlifting, the results may not have been representative of long-term well 

performance. The Property’s residential well was briefly test pumped in October 2008 and 

produced about 43 gpm with less than 9 feet of drawdown (specific capacity, Cs, of 4.9 gpm/ft). 

These values for yield and specific capacity are much greater than that reported for area wells 

and indicate either that the aquifer is unusually productive near the Property or that the well 

yields reported on well logs underestimated well production. 

Well depths in the vicinity of the Property are highly variable, ranging from 76 feet to a maximum 

of 332 feet below the ground surface (bgs). The data indicate a poor correlation between well 

depth and well yield. Well depth accounts for only 19 percent of the variance in well yield, 

indicating factors other than depth such as the number of gravel layers intersected influence 

yield. 

In addition to the data from the CaDWR listed in Table 1, neighbors provided supplemental 

information from nearby wells listed in Table 2. No drawdown data were provided and it is 

uncertain how the yields were measured. In this case, there appears to be a better correlation 

between depth and yield.

All of the area well logs reported similar geology - sticky clay, sandy clay, clayey gravel, sand, 

and gravel - that is consistent with either the descriptions of the Glen Ellen or Older Alluvial Fan 

units. Individual layers or strata ranged in thickness from a few feet to tens of feet. Often the 

sand and gravel layers were reported to be cemented (lithified), especially towards the bottom 

of deeper wells. Most well logs reported a change in color with increasing depth, from yellow 

near surface, to brown and then blue. The color change suggests a change from oxidizing to 

reducing conditions in the aquifer with increasing depth. Rapid changes or offsets in the 

stratigraphy over relatively short horizontal distances were also indicated. 

3.4.1 Groundwater Level Trends 

In the Healdsburg subbasin, water levels have remained relatively constant, with only one well 

reporting a decrease in the water table of about 10 feet (DWR, 2003, last update 2/27/04). In 

the Santa Rosa Plain subbasin, ground water “as a whole is about in balance, with increasing 

ground water levels in the northeast (closer to where the Property is located) contrasting with 

decreased ground water levels in the south” (California DWR, 2003). 

For most nearby wells, recent water-level data are not available with which to evaluate longterm water-level trends. However, the California Department of Water Resources at one time 

monitored water levels in two nearby wells (see Figure 1) and the data are available online 

(http:// wdl.water.ca.gov/gw/hyd). The hydrographs for these wells are provided in Figures 7 

and 8. 

Of the available hydrographs, the brief record for Well 08N09W15B001M located immediately to 

the north of the Property may be most representative of groundwater elevations beneath the 

Property. As shown in Figure 7, the data for this well indicate water levels annually fluctuated 

from about 115 to about 128 feet bgs.

The hydrograph for well 08N09W14L002M, located southeast of the Property, showed similar 

fluctuations. Although the graphs show measurable seasonal fluctuations, comparison of water 

levels from one year to the next did not show evidence of water level decline, at least not over 

the short period of record.

4.0 TEST WELL AND MONITORING WELLS 

4.1 Site Selection Process 

The test well and nested monitoring wells were constructed near the residence located at 1800 

Windsor River road. The residence and all accessible parts of the parcel are situated on the top 

of a relatively long, narrow ridge accessed by a steep driveway. This site was selected because 

it is roughly equidistant from nearby residential wells, it is outside of the Russian River Plain 

where new groundwater development is prohibited, and test pumping of the residence’s well 

indicated that the aquifer was reasonably productive in this area. At the time, it was the only 

parcel within the property with a well (other parcels to the east were added to the Property at a 

later date). The site is also the only area that had both good access and sufficient open space 

to set up the drill rig and ancillary equipment. The residential well is located near the base of a 

steep hillside which prevented drilling closer to it without major road construction. It was, 

however, useful during the pumping tests as a monitoring well. 

The test well and monitoring wells were constructed near the top of the ridge about 190 feet 

north of the residential well (see Figures 2 and 3). The test well and the two monitoring wells 

are approximately 75 feet apart. 

4.2 Well Construction Summary 

Vannucci Technologies of Woodland, California was contracted to drill, construct and test pump 

the wells. The wells were drilled by the direct mud-rotary method, using a TH-60 rotary drilling 

rig. Drilling operations began on December 2, 2008, as presented in Table 3. Water for drilling 

was obtained from the residential well. Composite samples of the formation materials were 

collected from the drilling fluid returns every five feet and logged by an onsite ECO:LOGIC 

hydrogeologist. No significant problems were encountered during drilling, with the exception of 

periodic loss of circulation (drilling fluid did not return to the surface because it infiltrated 

permeable zones in the formation). Following completion of drilling at each site, Dewey Data, 

Inc. of Stockton, California acquired borehole geophysical logs (spontaneous potential, shortand long-normal resistivity, 6-foot lateral resistivity, and natural gamma radiation).

275 gpm. 

12/20 A four-hour step-drawdown test was conducted. 

12/21-

A 72-hour constant-discharge test was performed. A water sample was collected at the 

end of the test. The well was allowed to recover for the 7 days. 

12/30/08 Data collection was terminated and data loggers were removed from the wells. 

4.2.1 Test Well Lithology 

The test well borehole lithology is summarized in Table 4 and shown on Figure 9. A photograph 

of the drill cuttings is provided in Figure 10. The field log of the borehole is provided in 

Appendix A. Three main units, or zones were differentiated primarily on oxidation, although the 

upper unit contained more sand and gravel than the deeper units. As shown on the logs, the 

bulk of the deeper materials were logged as “mudstone” of the Older Alluvial Fan Deposits 

(Qpoaf), because they locally appeared to be weakly lithified and roughly horizontally layered, 

as previously described. 

Samples of interbedded sediments obtained from mud rotary drill holes can be of variable 

quality because different size and density materials can ascend the borehole at different rates 

which tends to blend them together. Also, unconsolidated sand and gravel encountered at 

shallower depths can cave into the borehole and “contaminate” samples derived from greater 

depths. Because “chips” of weakly lithified materials were typically not obtained, it is possible 

that some of the material identified as “mudstone”, is actually separate thin layers of sand, silt, 

or clays. The recovered formation samples were compared to the borehole geophysical log in 

order to more accurately ascertain the location of the more permeable sand and gravel 

horizons.

During test well drilling, some drilling fluid circulation was lost from about 100 to 167 feet bgs. 

Increasing the viscosity of the drilling fluid resolved the issue. Drilling using a tri-cone drill bit 

slowed dramatically in the clay zones below 150 feet so the driller changed to a drag bit at 222 

feet which improved penetration rates. A hard zone was encountered at 417 feet, accompanied 

by a loss of circulation, but it is uncertain if the fluid was lost at that depth or at a higher interval. 

4.2.2 Monitoring Well Lithology 

The monitoring well borehole lithology is summarized in Table 5 and shown on Figure 11. A 

photograph of the drill cuttings is provided in Figure 12. The field log of the borehole is provided 

in Appendix A. 

Table 5: Monitoring Well Abbreviated Borehole Lithologic Log 

Depth Interval 

(feet bgs.) 

Major Unit Description 

0 to 120 Orange-brown, oxidized and moderately iron-oxide stained, unconsolidated 

sand, gravel and minor clay (upper zone). 

120 to 220 Mostly weakly lithified and weakly oxidized, light grey-tan, silty mudstone 

containing two layers of sand with gravel (middle zone). 

220 to 438 Unoxidized, olive-green-grey, weakly lithified sandy, silty mudstone, with 

several layers of sand and gravel (deeper zone). 

As shown in Figure 12, the samples collected below a depth of about 275 feet in the monitoring 

well contain more fine chips and appear to be slightly more lithified than those collected from the 

test well. The difference may be something as basic as a variation in the drill-tool downpressure exerted by the driller from one borehole to the next, or it might represent a subtle 

difference in lithology. However, as shown in Figure 13, the stratigraphy in both bore holes is 

very similar, but is offset slightly due to the 5.5-foot difference in elevation between the wells. 

Most gravel and clay horizons, and their associated geophysical-log responses, occur at very 

similar elevations in both wells. 

4.2.3 Geophysical Logs 

Following borehole completion, conventional geophysical logs, including spontaneous potential, 

point resistance, short- and long-normal resistivity, lateral resistivity, and natural gamma 

radiation, were acquired. A condensed printout of the geophysical logs is provided in Figures 9, 

11 and 13. The complete logs are provided in Appendix B. The geophysical logs were 

correlated with the geologic logs of the formation materials. This interpretation identified the 

most permeable water bearing horizons to be completed with well screen, the amount of backgrouting performed before well construction, and the depth of blank casing.

4.3 Well Construction Details 

The well construction details are summarized in Table 6 and illustrated in Figures 9 and 11. 

The test well was designed specifically to derive groundwater from the middle and deep 

lithologic units. The deep monitoring well was constructed to intercept the same lithologic units 

as the test well to facilitate analysis of the pumping-test data. The shallow monitoring well was 

designed specifically to investigate the vertical hydraulic connection between the upper 

lithologic unit and the lower two units.

4.4 Well Development 

The purpose of well development is to remove residual drilling fluids from the well, reverse 

formation damage caused by drilling and well construction, and enhance the hydraulic 

conductivity of the aquifer near the well/formation interface. Formation damage includes 

formation plugging due to drill mud invasion or the buildup of an impermeable “wall cake” on the 

formation/borehole interface. Initial well development was accomplished by air-lifting using the 

drill-rig’s compressor. Drilling mud and development water were dispersed on the nearby land 

surface. The wells were developed until the discharge was visibly clean. 

Final development of the test well was accomplished by surging with the test pump at rates as 

high as 275 gpm for several hours (see Figure 14). 

FIGURE 14: Photograph of Test Well Discharge

(Well was pumped at rates as high as 275 gpm) 

4.5 Water Levels 

Following well construction, and prior to initiating the testing program, static (or non-pumping) 

water levels were measured in each well. These are listed in Table 7. The water levels may not 

be rigorously static because they still may have been recovering from earlier pumping.

5.0 WELL TESTING 

The test program included a step-drawdown test and a constant-discharge test, plus a recovery 

period after each test. Step testing entailed pumping the well at progressively higher rates while 

monitoring water levels in the wells. The purpose of the step test was to evaluate the 

performance of the test well over a range of pumping rates, the efficacy of development, and the 

overall well efficiency. The results were used to select a pumping rate for the subsequent 

constant-discharge test that would stress the aquifer but could be maintained for the test’s 

duration. The constant-discharge test entailed pumping the test well at a constant rate for 72 

hours while monitoring water levels in all the on-site wells. The data from this test were used to 

evaluate the hydraulic characteristics of the aquifer that influence long-term well performance 

and interference between pumped wells. 

Water levels were monitored in the test well, the shallow monitoring well, the deep monitoring 

well, and the residential well. The locations of the wells were field-surveyed prior to the test 

(see Figures 2 and 3, and 15 through 18). The shallow and deep monitoring wells are located 

approximately 75 feet from the test well and are situated approximately 5.5 feet higher in 

elevation. The residential well is located approximately 195 feet from the test well and 54 feet 

lower in elevation compared to the test well. No construction data are available for the 

residential well other than a depth of 187 feet (based on a measurement made during the 

October 2008 test). The elevation of the water level in the residential well differs from the 

shallow monitoring well and is similar to water levels in the test well and deep monitoring well. 

As a result, it is presumed the residential well has more in common with the test well and deep 

monitoring well than it does with the shallow monitoring well.

5.1 Equipment 

Air lift development indicated that the test well was capable of producing more than 100 gpm, so 

Vannucci Technologies installed a 30-horsepower submersible pump capable of pumping 275 

gpm to conduct the pumping tests. The pump, installed at a depth of 285 ft bgs, was powered 

by a diesel generator. 

The pumping rate was measured with a McCrometer in-line totalizing flow meter (see Figure 

15). Water was discharged through about 20 feet of 4-inch-diameter hose to the ground surface 

(see Figures 14 and 15). Discharge was directed downhill toward a drainage located below the 

well site (Figure 18). 

Groundwater levels in the test well were measured with an In-Situ, Inc. LevelTROLLTM data 

logger with a 100 psig (pounds per square inch, gauge) pressure transducer. Both monitoring 

wells and the residential well were monitored using either In-Situ LevelTROLLTM or 

MiniTROLLTM data loggers equipped with 30 psig pressure transducers. The data loggers were 

accessed through a laptop computer. The data logger measurements were verified with manual 

measurements using a water-level sounder at the start up and conclusion of testing. The 

original test plan included monitoring off-site residential wells. Three offsite wells were 

inspected prior to the tests for use as potential monitoring points, but all of them would have 

required wellhead modifications to facilitate data-logger installation. Consequently, no off-site 

wells were monitored.

hydrograph data show that the deep monitoring well and residential well responded to pumping 

the test well. Only very small fluctuations in the shallow monitoring well water level were

5.3 Constant-Discharge Test 

Constant-discharge testing ensued the day following the step-drawdown test, after water levels 

in the wells recovered overnight. The test well was pumped for 72 hours and water levels were 

monitored for seven days after pumping ended. The test is summarized below: 

Pre-pumping water level: 126.354 feet below the top of the stilling well (top of stilling well 

was 2.6 feet above the ground surface). 

Pumping commenced: 08:10 hours 12/21/08. 

Average discharge rate: 150.3 gpm. 

Pumping level at the conclusion of the pumping test: 151.99 feet below the measuring 

point.

Drawdown in the pumped well at the conclusion of the pumping test: 25.73 feet (Cs=5.84 

gpm/ft). 

Drawdown and recovery data from the test are illustrated in Figures 21 and 22. The deep 

monitoring well and residential well clearly responded to pumping the test well. However, 

testing did not elicit an obvious response in the shallow monitoring well. The entire set of test 

data and analysis results are provided in Excel© format on a CD-ROM in Appendix C.

6.0 PUMPING-TEST DATA ANALYSIS 

Analysis of the test data was accomplished in two phases. The first phase incorporated 

classical graphical analysis of the data as testing progressed using the Cooper-Jacob 

approximation of the Theis Equation. This preliminary analysis provided initial estimates of 

transmissivity and storage coefficient. It also allowed an assessment of whether or not the test 

goals had been achieved. The second phase of the analysis used the computer program 

AQTESOLV PRO for Windows (Version 4.50.002, HydroSOLVE, Inc., 2007). AQTESOLV 

compares the observed drawdown data to theoretical or “type” curves generated for a large 

number of analytical solutions for unsteady flow to wells for a number of aquifer types and 

conditions. The method of Dougherty and Babu (1984) provided a reasonable fit to the 

observed data. Dougherty and Babu developed an analytical solution to non-steady flow to a 

fully- or partially-penetrating well in a confined aquifer. Additionally, a reasonable fit to the 

observed data was obtained using the method of Moench (1997), which describes unsteady 

flow to a well in an unconfined aquifer with delayed yield from storage. 

All solutions required the use of two no-flow (or discharge) aquifer boundaries, which are likely 

related to faults that displace less permeable materials against permeable strata or cause 

smearing of clay along the fault planes, or other lateral discontinuities in the aquifer. When 

boundaries are enabled in AQTESOLV, the program automatically generates image wells to 

simulate their effect according to the specified boundary locations. The software requires that 

boundaries either meet at right angles, or be parallel. To enable boundaries, relative X and Y 

coordinates are entered for the well locations and the boundaries. 

Although the well locations were field-surveyed, the location of the boundaries relative to the 

wells could not be determined from field observations and their exact location and orientation in 

the field are unknown. In reality, they are unlikely to be vertical planes that meet at right angles. 

The calculated boundary locations were determined through trial and error, and their distance 

from the wells was adjusted manually until the best fit of the data was obtained. The location of 

the boundaries relative to the wells in the model has a significant effect on the results, and a 

boundary orientation that provided a good data fit for the pumped well did not necessarily 

provide an exact fit for data from both the deep monitoring well and the residential well. 

The shallow monitoring well showed no obvious response directly attributable to pumping and 

was not used in the main analyses. However, a close look at the data suggests a very subtle 

response that provides some insight into the vertically anisotropic nature of the aquifer. 

Other variables that influence the analytical results, besides boundary locations, include skin 

factor (Sw), well loss coefficients (C), and well-loss exponent (P), and possibly the deviation of 

the well from the vertical (which can influence the effective distance between wells if the wells 

are not vertical). In addition, as discussed in Sections 4 and 5, the aquifer may also be laterally 

heterogeneous, and the effects of this can mimic either no-flow or recharge boundaries. 

For each analytical solution, the observed drawdown data were plotted for direct comparison to 

the type curves based on the aquifer and well properties determined through the analysis. 

These solutions are plotted in Figures 23 through 25. As described in the following sections, 

even though the drawdown data collected from the wells are very precise, because of the large 

number of variables involved in the analysis, exact mathematical solutions for all the observed 

drawdown data could not be determined with a single set of well and aquifer parameters. 

However, the results are reasonably consistent and provide a reasonable estimate of the aquifer 

parameters, well yields, and off-site impacts.

6.1 Step Test Results 

The results of the analysis of the step-test data using the method of Dougherty and Babu are 

shown in Figure 23. The small skin factor and well losses (indicated by small well loss 

coefficient and exponent) indicate the test well is very efficient for the rates at which it was 

pumped. Figure 23 shows that the same set of aquifer properties also provide a good fit for the 

late-time drawdown and recovery for the deep monitoring well, although it does not provide as 

good a solution to the early-time drawdown and recovery data. 

There is a poor fit to the residential well data using these aquifer properties. Whereas, the deep 

monitoring well is located about 75 feet from the test well, the residential well is located about 

190 feet from the other wells. Despite its greater distance from the test well, the residential well 

had an almost identical response to the pumping, and had slightly greater drawdown. This 

discrepancy is likely related to the position of the modeled no-flow boundaries, or some other 

aquifer heterogeneity that provides enhanced permeability in the area between the test well and 

the residential well. Despite, numerous attempts to re-orient the boundary conditions, no 

combination could be found that matched the response of all three wells.

6.2 Constant-Discharge Test Results 

The constant-discharge test data were initially analyzed in detail using the Dougherty and Babu 

analytical model for a confined aquifer. The results are shown in Figure 24. A second 

evaluation using the unconfined model of Moench yielded similar results (Figure 25). Each 

analysis incorporated two no-flow boundaries at various distances from the wells. As in the step 

test, because the aquifer is heterogeneous and multiple boundaries appear to be present, no 

single set of aquifer properties provided a unique solution to all of the data for all of the wells. 

However, the drawdown data for the pumped well matches the type curve quite well except for 

very late-time recovery. A similar good fit is exhibited by the data from the deep monitoring well, 

again with the exception of the late-time recovery data.

FIGURE 25: Results of Analysis of the Lytton Test Well Constant-Discharge Test using 

the Method of Moench. 

One aspect of the test that is not explained very well by the analytical results is the fact that the 

domestic well responds quicker than the deep monitoring well, despite its greater distance form 

the pumped well. Qualitatively, this suggests the aquifer is horizontally anisotropic. Another 

aspect of the test that is not clearly explained by the analysis is the fact that the wells recover 

quicker than the analytical models suggest they should. The rapid recovery may in part be due 

to the extensive developmental and step test pumping over the two days prior to the start of the 

constant-discharge test. Because of the earlier pumping, the aquifer may not have fully 

recovered prior to the start of the test. 

Despite these apparent inconsistencies, the results of all of the analyses indicate a high degree 

of confidence in the tests and the analytical results. The following values appear to be 

reasonable for the aqufier as a whole in this area:

Transmissivity: Approximately 2,000 feet2

/day (15,000 gallons per day per foot width 

of aquifer under a unit hydraulic gradient). 

Coefficient of storage: 0.015. The value for coefficient of storage (0.015) is 

representative of an unconfined to semi-confined aquifer. 

Boundaries: Two or more no-flow boundaries are present, but their exact locations are 

uncertain, and cannot be accurately located without additional 

observation wells. 

The static water level in the shallow monitoring well, which was more than twenty feet higher 

than the test well and deep monitoring well, does not appear to represent a perched aquifer 

(there was no unsaturated material between the screened zones). Instead a large downward 

gradient probably exists, but downward groundwater flow is restricted by laterally-continuous 

clay strata. 

The data for the shallow observation well were not initially analyzed in detail because this well 

did not appear to respond to test well pumping. Examination of the shallow well data provided 

in Figure 22 (the graph of drawdown versus logarithm of time for the constant-discharge test) 

did not indicate any measurable change in water levels at the scale at which it was plotted. For 

this reason, the data were plotted at an expanded scale as shown in Figure 26

At the expanded scale, comparison of the water level data from the shallow monitoring well and 

local barometric pressure shows that water levels in the well (and, by extension, in the aquifer) 

clearly respond to changes in barometric pressure. The rise, and the approximately 0.4 foot 

decline, in water level following the completion of the pumping test is almost certainly a result of 

the large increase (equivalent to approximately 0.8 feet of water) in barometric pressure. 

However, a very small, delayed response to pumping of the test well might be construed to 

begin a few hours before the end of the constant-discharge test (about 3,600 minutes into the 

test) that might be caused by something other than a barometric pressure change. The 

response is suggested by a separation between the water level and pressure plots that begins 

about midnight on 12/24 and indicates perhaps 0.15 to 0.2 feet of drawdown (at a pumping rate 

of 151 gpm). A larger divergence occurs about a day after cessation of the test (5,760 minutes) 

The small possible response to pumping the test well clearly shows that the fine-grained 

sediments present between the shallow and deep well screens are not very permeable. 

To estimate the vertical hydraulic conductivity of these fine-grained sediments, and to assess 

the potential impacts to offsite, shallow residential wells, the drawdown data were also plotted at 

an expanded scale in AQTESOLV as shown in Figure 27. The construction of both the test well 

and the shallow monitoring well were changed to reflect partial penetration of the aquifer. The 

test well construction had the screen beginning 40 feet below the static water level, with a total 

aquifer thickness of 260 feet. This is reasonable, since the static water level in the Shallow MW 

was at 102 feet and the upper screen in the test well was set at 141 feet. The Shallow MW 

construction had the screen set at the water table, and the bottom was set at a depth of 23 feet 

below the water table (the depth of the filter pack to the top of the intermediary bentonite seal). 

The aquifer parameters calculated above were modified to reflect the partial penetration (the 

transmissivity was increased slightly), and the ratio of vertical to horizontal hydraulic conductivity 

(Kz/Kr)) was varied until it provided a response in the modeled shallow monitoring well similar to 

that shown in Figure 26. As shown in Figure 27, a reasonable fit was provided with Kz/Kr of 

about 0.00016

From this ratio, the vertical conductivity of the intervening fine-grained sediments can be

= 4.93 x 10-7 cm/s 

This value is considered reasonable for the clay horizon that separates the upper unconfined 

aquifer (screened by the Shallow MW), from the lower pumped aquifer, since clay conductivity 

typically ranges from 1x10-6 to 1x10-9 cm/sec (Fetter, 1980). As described below in Section 7.1, 

these parameters were incorporated into the analysis of interference drawdown in shallow 

offsite wells.

7.0 PREDICTED PRODUCTION WELL PERFORMANCE 

ECO:LOGIC estimated that the water demand for Alternative B of the Project would be 75,000 

gallons per day (average continuous demand of 57 gpm) (ECO:LOGIC, 2009). This average 

demand was incorporated into an analysis of the drawdown in a hypothetical production well 

and in the aquifer at various distances from the pumped well. Predictions of the long-term 

performance of a production well at the location of the test well were made using the “forward 

modeling” capabilities of AQTESOLV and invoking the analytical method of Dougherty-Babu 

(1984), one of the analytical methods used to analyze the test data. A series of simulations 

were performed over a range of pumping rates. 

The yield of a production well is influenced primarily by the hydraulic properties of the aquifer. It 

is influenced to a lesser degree by the diameter of the well, its hydraulic efficiency, and the 

elevation of the top of the perforations. The principal assumptions for the analysis of the 

performance of a production well at the site included: 

 The aquifer is infinite in aerial extent. 

 The aquifer is uniform and isotropic. 

 The pumped well and other wells fully penetrate the aquifer. 

 The well is constructed with 10-inch diameter casing within an 18-inch diameter 

borehole. 

 No recharge to the aquifer occurs (all water is derived from storage in the aquifer). 

 The well is 80% efficient. Properly-constructed wells commonly approach efficiencies of 

80%, while wells with 100% efficiency are uncommon. 

 The well is continuously pumped, 24 hours per day, 7 days per week. 

 Aquifer properties used in the simulation are those calculated from the test data -

transmissivity of about 2000 feet2

/day, a coefficient of storage of 0.015, and two no-flow 

boundaries. 

 The top of the well screens in a production well would be placed 20 feet below the static 

water level, or at 146 feet bgs. This construction would seal off groundwater in the 

upper oxidized zone, but allow production from the first sand and gravel layer observed 

below that depth. 

 The maximum recommended drawdown for a production well is 25 feet. This value is 

derived from the difference between the elevation of the static water level and a water 

level a few feet below the top of the proposed screen interval. During peak pumping 

periods, additional drawdown and greater production is possible, but the potential for 

cascading water and subsequent aeration exists. However, no entrained air was 

observed in the discharge during developmental pumping and this criterion may be 

overly conservative. 

The simulation results are illustrated in Figure 28 and indicate that a production well could be 

continuously pumped at 75 gpm for one year in the absence of recharge and only slightly 

exceed 25 feet of drawdown. 

Note that the analysis is based on the average pumping rate to meet average daily demand. 

Peak demands will be higher and it is reasonable that the well will be equipped with a pump that 

will discharge more than 75 gpm for short periods. This will result in short-term larger 

drawdown in the pumped well, but the average drawdown would be expected to follow the trend

App A - Lytton Test Well Report Final 6 ALT 09-30-10 42 10/1/2010 

depicted in the graphs. If larger drawdowns do cause entrained air in the discharge as a result 

of cascading water, it might be necessary to construct an additional well.

FIGURE 28: Predicted Performance of a Production Well at the Lytton Site 

7.1 Predicted Interference with Nearby Offsite Wells 

A consequence of groundwater production is a lowering of the water table or piezometric level in 

the aquifer. This results in a “cone of depression” surrounding a well, wherein drawdown is 

greatest near the well and decreases with distance from the well. The analytical method used 

to predict well performance in Section 7.0, above, was also used to estimate possible drawdown 

in the aquifer at various distances from the pumped well. The drawdown in other wells is 

commonly referred to as “interference.” The nearby wells of concern include one located about 

700 feet to the east, and one about 850 feet to the southwest (see Figure 2). Modeled potential 

interference arising from pumping a production well at various rates is displayed in Figure 29. 

From the figure, after one year of continuous pumping, about seven feet of interference might 

be expected at a pumping rate of 50 gpm at a distance of 850 feet. At a pumping rate of 75 

gpm, the analysis indicates up to eleven feet of interference drawdown in the nearest offsite 

wells. The actual amount of interference a particular off-site well may experience will, of course, 

be governed by the actual hydraulic properties of the aquifer, the presence of undetermined 

heterogeneities, and the exact location of the no-flow boundaries identified in the pumping tests. 

Interference with the residential well to the east is considered more likely because the well to 

the southwest is located on the opposite side of the northwest-trending ravine described in 

Section 4. This ravine is presumed to represent one of the no-flow boundaries identified in the 

pumping test responses. Wells located on the opposite side of faults would likely have 

diminished potential for interference.

Drawdown calculated for a well located 850 feet

(1984).

FIGURE 29: Predicted Interference Drawdown in Offsite Well Located Approximately 850 

Feet from a Production Well at various pumping rates. 

To calculate the potential interference drawdown in offsite wells at a constant pumping rate of 

57 gpm (the anticipated average daily demand for the project), two scenarios were modeled 

using AQTESOLV. For offsite wells that are relatively deep and are screened below the upper 

oxidized zone (similar to the test well), the initial set of aquifer parameters determined through 

the analysis of the test data were used, and it was assumed the wells fully penetrate the aquifer. 

In this scenario, the ratio of Kz/Kr has no effect on the model results. It was further assumed 

that all of the wells are located within the same structural block as the pumped well (as stated in 

previous sections of the report, two no-flow boundaries were required to gain reasonable model 

results). The drawdown calculated for wells at three different distances from the test well are 

shown in Figure 30. 

For offsite wells that are shallow and are screened only in the upper oxidized zone, drawdown 

was evaluated after assigning partial penetration effects to both the shallow wells and the 

production well. Note that this consideration (assuming the pumped well and shallow 

observation wells are completed in a single aquifer) results in a slightly greater transmissivity. 

The results for wells at three different distances from the test well are shown in Figure 31. In 

this case, the ratio Kz/Kr has a measureable effect, and indicates that drawdown in shallow, 

partially-penetrating wells will be less than that in deeper, fully-penetrating wells. Both models 

assume no recharge to the aquifer (which is unlikely) and that the wells are located within the 

same fault block as the pumped well. If recharge occurs, or if offsite wells are located on the 

opposite side of boundaries, the drawdown will be less than those shown in the Figures.

The radius of influence of the well can be determined from the calculated drawdown at various 

distances from the pumped well. As shown in Figure 32, after pumping for one year at 57 gpm, 

the radius of influence from the pumped well within the proposed boundaries will be on the order 

of 10,000 feet. Assuming an aquifer thickness of 300 feet, the estimated drawdown (3 to 8 feet 

depending on distance from the pumped well and well construction) equals about 1 to 3 percent 

of the available aquifer. Again, these estimates assume that no recharge occurs to the aquifer. 

In reality, some recharge does occur. As described previously in Section 3.4.1, groundwater 

levels in the Santa Rosa Plain have been relatively stable over the years despite groundwater 

pumping, an indication of groundwater recharge. Consequently, actual drawdown is likely to be 

less than the models predict, and estimated impacts to the overall aquifer are not considered 

significant. A hypothetical east-west cross section showing the possible drawdown effects is 

provided in Figure 33. Note that the scale has 10x vertical exaggeration.

7.2 Predicted Impact to Regional Groundwater Resources 

The Lytton property is located within the Santa Rosa Plain Subbasin, but very near the 

boundary with the Healdsburg Area Subbasin. For the Santa Rosa Plain Subbasin, the DWR 

calculated the groundwater storage capacity to be 4,313,000 acre-feet (af), with a volume of 

3,910,000 af held in storage. Average annual natural recharge (for the period 1960 through 

1975) was estimated to be about 29,300 af, while average annual pumping during the same 

period was approximately 29,700 af. Most groundwater pumping and areas of groundwater 

level declines, were reported for the southern portion of the subbasin, many miles from the 

Lytton site. The proposed Lytton project, if groundwater were produced at a constant rate of 57 

gpm, would produce 92 af annually. A portion of this water would be returned to the basin after 

treatment. The Lytton project would therefore pump approximately 0.002% of the groundwater 

in storage, an amount considered insignificant. 

For the Healdsburg Area Subbasin, Bulletin 118 reported that there are insufficient data 

available in order to provide a water budget. Groundwater storage capacity for the basin was 

estimated at 489,000 af, while groundwater in storage for the year 1980 was estimated to be 

390,000 af. The Lytton project would pump approximately 0.02% of the groundwater in storage, 

an amount also considered insignificant. 

Finally, the town’s General Plan does not identify any long-term water level declines in the area 

aquifers, nor does it identify any other deleterious cumulative impacts to them. Since analysis 

of the pumping test results indicate only minor effects to the closest area wells (even using 

conservative assumptions such as no annual recharge to the aquifer), no broader cumulative 

impacts to regional groundwater are anticipated. 

7.3 Predicted Impacts to Local Surface Water Resources 

The closest surface water to the Property includes an unnamed branch of Windsor Creek, about 

3,500 feet to the east of the test well, and a flooded gravel pit known as the McLaughlin Pond, 

about 2,000 feet to the west (see Figures 5 and 33). The creek flows mostly in response to 

precipitation events, although some interaction with the shallow groundwater zone is possible. 

The McLaughlin Pond is a former gravel pit that was excavated below the water table into highpermeability deposits of sand and gravel in the Russian River flood plain. It is separated from 

the river by a berm of un-mined gravel. 

As shown in Figure 33, modeling indicates that small water level declines in the shallow aquifer 

in the area of the creek and the pond are possible. However, since the evaluation used the 

conservative assumption of no annual aquifer recharge, the influence of a production well on the 

unconfined aquifer in both areas would likely be less. This assumption is particularly unlikely at 

the McLaughlin Pond, because it is in direct hydraulic connection to the river. 

Had the pumping test data indicated an effect on the shallow aquifer in the Russian River valley, 

a flattening of the drawdown curve from a recharge boundary would have been expected. 

Instead, two no-flow aquifer boundaries were identified. These boundaries are likely faults or 

other lateral discontinuities that reduce the movement of groundwater to a well from certain 

directions. The exact location and orientation of the boundaries are unknown, but a reasonable 

location for one boundary would be the northwest-trending ravine that exists to the southwest of 

the well site. This feature parallels many other regional faults and could help to hydraulically 

isolate the well site from the river valley.

8.0 PRODUCTION WELL DESIGN PARAMETERS 

Ten samples from the test well drill cuttings, representative of both the coarser and finer sands 

encountered during drilling, were submitted to a geotechnical laboratory for sieve analyses. The 

results are plotted in Figure 34. The materials are classified as silty sand, clayey sand, and 

various sand, silt and gravel combinations. To reduce the potential for sand pumping (as occurs 

in the existing residential well), a relatively fine slot size and filter pack should be used, as 

described below. All well depths are approximate and will depend on the location and elevation 

of the new production well, and must take into account any geologic variations encountered 

during drilling: 

 Well depth: 350 feet. 

 Conductor casing: 24 inch diameter casing installed to a depth of 40 feet and grouted in 

place. The purpose of the conductor casing is to maintain borehole stability through 

some of the non-cohesive gravels that overlie the aquifer in this area. The borehole for 

the conductor casing can be drilled by the mud-rotary or bucket auger method.

 Production well borehole diameter: 18 inches (below the conductor casing). The 

production borehole should be drilled below the conductor casing using the reverse 

circulation drilling method to minimize formation damage. 

 Well casing and screen diameter: 10 inches. 

 Casing material: Low carbon steel. 

 Screen material: Type 316L stainless steel. Casing and screen should be joined with a 

dissimilar metals connector to minimize the potential for galvanic corrosion. 

 Screened interval: Approximately 145 to 185, 230 to 250, and 305 to 345 feet below 

land surface. The blank casing from 185 to 230 would provide a reasonable location for 

the pump intake. 

 Filter pack: Either Colorado Silica 8x20 or 8x16 mesh sand. This is based on a D70 of 

approximately 0.004 and non-uniform formation material (refer to Figure 29 and 

Appendix D). The final filter pack selected should be based on an up-to-date size 

distribution obtained from the supplier.

 Slot aperture width: 0.035 inch. This is based on the D90 of 0.032 inch for the 8x16 or 

8 x 20 mesh sand.

9.0 WATER QUALITY 

Prior to the test well program, no groundwater quality data were available for wells in the 

immediate vicinity of the project. As described by Ford (1975), 

“groundwater in the Glen Ellen Formation has a greater range of character than any 

other formation in Sonoma County. Some of the best and some of the poorest quality 

water is obtained from this formation. Wells generally 100 feet deep yield a magnesiumbicarbonate water of moderately good quality; unusually high content of nitrate may be 

present. Wells up to 800 feet in depth yield moderately good quality sodium bicarbonate 

water. Very deep wells, such as those greater than 1,000 feet, yield a poorer quality 

sodium bicarbonate water. At scattered localities throughout the formation, boron 

concentrations of up to 1.0 mg/L have been reported, as has water containing over 90 

percent sodium” (page 157). 

For the Santa Rosa Plain subbasin, the California DWR (2003) reported that “in the vicinity of 

Windsor, magnesium chloride is present in the shallow aquifer to a depth of about 100 feet”. 

Although overall groundwater quality is good throughout the subbasin, individual well owners 

“reported many complaints about the color and /or taste of the water”. Elevated concentrations 

of iron, manganese, and in some areas boron, may locally be present. 

A water sample was collected from the test well discharge near the conclusion of the constantdischarge pumping test and analyzed for all the physical, chemical, and radiological constituents 

regulated under Title 22 of the California Code of Regulations. The sample bottles were 

submitted to either BSK Analytical Laboratories in Sacramento, California, or to Sierra 

Environmental Monitoring (SEM), of Reno, Nevada, both California-certified laboratories. The 

analytical results are provided in Table 9. The laboratory report is provided in Appendix D. In 

summary, the groundwater contains relatively low concentrations of Total Dissolved Solids but 

exceeds California and Federal drinking water standards for Arsenic and Manganese. 

Treatment to remove these components is fairly routine and removal is relatively easy to 

accomplish. Note also that an occasional faint odor of hydrogen sulfide was thought to emanate 

from the pumping test discharge, but no evidence of hydrogen sulfide is reflected in the 

analytical results.

September 2010 Biological Assessment

1.0 INTRODUCTION 

Analytical Environmental Services (AES) has prepared this Biological Assessment (BA) for the Lytton 

Residential Development Project (proposed project). This BA has been prepared in support of an 

application to the United States Bureau of Indian Affairs (BIA) to place approximately 124.12 acres of 

land into federal trust (proposed action) for the Lytton Rancheria of California (Tribe) and the 

construction of a residential development complex that would include housing units and other associated 

facilities. This BA has been prepared to facilitate consultation with the U.S. Fish and Wildlife Service 

(USFWS) and National Marine Fisheries Service (NMFS) and was prepared in accordance with legal 

requirements set forth under Section 7 of the Federal Endangered Species Act (FESA) (16 USC 1536 (c)) 

concerning the effects of the proposed project. 

The purpose of this BA is to review the proposed project in sufficient detail to determine the extent to 

which the project may affect any federally listed or candidate special-status species, designated or 

proposed critical habitat, and designated or proposed Essential Fish Habitat (EFH). For the purposes of 

this BA, federally listed species include those plant and animal species that are listed as endangered or 

threatened under the FESA of 1973, species that are formally proposed for listing, and species that are 

listed as candidate species and species of concern by USFWS and NMFS. This BA addresses the 

following goals: 

• Characterizes the habitat types present within the project site; 

• Evaluates the potential for the occurrence of federally endangered, threatened, proposed, 

or candidate species within the action area; 

• Utilizes the best scientific and commercial information available to assess the potential 

for the proposed project to adversely impact federally listed species and designated 

critical habitat; and 

• Recommends mitigation measures designed to avoid or minimize project-related impacts. 

1.1 PROJECT LOCATION

The project site is located within the Russian River Valley, west of Interstate Highway 101, east of the 

Russian River, and is approximately one mile west of the Town of Windsor, within unincorporated 

Sonoma County, California (Figure 1). The project site occurs within Sections 14, 15, and unsectioned 

areas of Molinos, Township 8 North, and Range 9 West, Mount Diablo Baseline and Meridian (MDBM) 

in the “Healdsburg, CA” U.S. Geological Survey (USGS) 7.5-minute topographic quadrangle (USGS, 

1993) (Figure 2). It is located within the Russian Watershed, Hydrologic Unit Code #18010110 (USGS, 

1978). The project site is composed of fourteen Sonoma County assessor parcel numbers (APNs) which 

are proposed to be put into trust for the Tribe. These APNs, listed in order from west to east, are

1.2 PROJECT DESCRIPTION

The proposed action and associated project would include the transfer of approximately 124.12 acres of 

land into federal trust for the Tribe and construction of Tribal housing units, a community center, a retreat 

facility, a roundhouse structure and associated facilities. More extensive information regarding the 

proposed project development is provided in the Final Environmental Assessment (EA) for the Lytton 

Residential Development (AES, 2011). 

As discussed in the Final EA, the preferred alternative for the proposed project is Alternative A, which 

includes 147 residential units, where the Town of Windsor provides the sewer and water connections. 

Alternative B is similar to Alternative A, but includes the construction of water and wastewater facilities 

for on-site water and wastewater treatment and reclamation. Alternative B is further analyzed by two 

options: the first option involves on-site tertiary treatment and seasonal reclamation with surface water 

discharge when permitted (October 1-May 14), or when waste discharge flows is greater than one percent 

of the receiving stream’s flow. The second option involves complete on-site tertiary treatment and

reclamation. Alternative C includes the on-site water and wastewater facilities, but provides only 55 

residential units. Alternative D is the No-Action alternative. Although Alternative A is the preferred 

alternative; Alternative B has the largest on-site footprint due to the addition of the water and wastewater 

treatment/ reclamation facilities and an approximately four-acre effluent detention basin in the northern 

portion of the project site. Treated effluent irrigation land will include landscaped areas such as parks, 

housing landscaping and other areas. As such, the site plan for Alternatives B was used for this analysis 

because it has the largest on-site potential impacts to biological resources. The site plan for Alternative B 

is presented as Figure 4 and proposed project components are briefly explained below. 

HOUSING

Under Alternatives A and B, approximately 147 housing units could be constructed, utilizing three 

different housing types. Low-density housing (approximately 95 units) would act as single-family 

homes, to be connected by the primary or secondary roadways throughout the trust property. Cottagestyle housing (approximately 24 units) would consist of smaller homes, predominantly located in the 

middle section of the trust property to the west of the proposed Community Center. High-density housing 

(approximately 28 units) would serve as fourplexes just east of the proposed Community Center (Figure 

4). Alternative C would consist of 35 units of low-density housing, 12 units of cottage-style housing and 

8 units of high-density housing. 

ROAD IMPROVEMENTS

A new two-lane roadway would be constructed for the proposed project to provide access to the 

residences and facilities on-site. This new roadway would connect to Windsor River Road at three 

separate locations on APNs 066-300-031, 066-300-033, and 066-191-021 and would traverse the entire 

project site (Figure 4). Stop signs would be installed at the three project access driveways on Windsor 

River Road. 

DRAINAGE AND GRADING

The topography on-site generally drains storm and surface waters to the east and to the west, with both 

directions ultimately connecting to the Russian River. Drainage to the west of the project site occurs via 

drainage ditches that are part of the Town of Windsor’s roadside stormwater drainage system, which flow 

to an old gravel quarry that is adjacent to the Russian River. Drainage to the east of the project site 

occurs via an ephemeral drainage that outlets into an unnamed tributary to Windsor Creek and flows to 

Mark West Creek before joining the Russian River. 

If Alternative B or C is chosen, the Tribe shall obtain a National Pollutant Discharge Elimination System 

(NPDES) General Permit from the U.S. Environmental Protection Agency (USEPA) for all construction 

site surface and storm-water runoff during the construction phase of the proposed project in compliance 

with the Clean Water Act (CWA). A Storm Water Pollution and Prevention Plan (SWPPP) would be 

prepared, implemented, and maintained throughout the construction phase of the development, consistent 

with USEPA General Permit requirements. The SWPPP would detail appropriate Best Management

Practices (BMPs) to be implemented during construction and post-construction operation of the proposed 

project. Due to the variability of topography within the project site, grading would be required in various 

areas for construction of the proposed project. A comprehensive grading and drainage plan will be 

prepared for the proposed project and will meet the current USEPA standards. 

UTILITIES

Electrical and telephone infrastructure facilities are currently located near the project site. The Tribe will 

coordinate with Pacific Gas & Electric (PG&E) and AT&T regarding the extension of services to the 

project site. The project would use propane, not natural gas, which it will contract from local supply 

companies in the area. 

WATER SUPPLY

The project site is located outside of the Town of Windsor boundaries, with the exception of APN 066-

050-047. However, APNs 066-191-017, 066-191-018, 066-191-022, 066-050-040 and 066-050-047 

which comprise approximately 41.23 acres of the project site, are within the sphere of influence of the 

Town of Windsor (Table 1). Under Alternative A, the Tribe would tie into the Town of Windsor public 

water supply system, which would require the Tribe to enter into a service agreement and for the Town of 

Windsor to amend its General Plan and voter approval to allow for connections outside town limits to 

occur. Under Alternatives B and C, the Tribe would provide its own water supply to the project site from 

on-site well(s) as detailed in the water and wastewater feasibility study that has been prepared for the 

project site (Eco:Logic, 2010a). The on-site water supply system for the project site would meet or 

exceed federal water quality and safety standards and would be subject to the required federal inspections 

for drinking water. 

WASTEWATER TREATMENT AND DISPOSAL

Under Alternative A, the Tribe would dispose of wastewater from the project site through a connection to 

the nearby Windsor municipal sewer system. The Tribe would be required to enter into a service 

agreement with the Town of Windsor, which is responsible for the treatment, storage, and disposal of the 

Town’s wastewater. Under Alternatives B and C, the Tribe would build a wastewater treatment and 

reclamation facility (WTRF) to treat wastewater to tertiary standards. If the first option under Alternative 

B is chosen, discharge from the WTRF would be reclaimed on-site to the maximum extent feasible, with 

the remaining treated effluent to be discharged to surface water at one of two locations. Surface water 

disposal is regulated under the conditions of a NPDES permit from the USEPA for wastewater treatment 

and disposal in compliance with the CWA. Under the second option of Alternative B, complete on-site 

disposal of treated effluent would involve storage/ detention basins and landscape irrigation. As shown in 

Figure 4, the WTRF would be constructed in the northwestern (location 1) or southeastern corner 

(location 2) of the project site. 

If located in the northwestern corner (location 1), the WTRF would discharge tertiary treated wastewater 

onsite (anticipated to be held in trust by the federal government prior to this occurring), where it would 
Biological Assessment 

Analytical Environmental Services 9 Lytton Residential Development

September 2010 Biological Assessment

flow into a roadside drainage adjacent to Windsor River Road. As shown in Figures 4 and 5, this 

drainage flows off-site and into the Town of Windsor’s roadside stormwater drainage system, near the 

intersection of East Side Road and Windsor River Road. If the WTRF is located in the southeastern 

corner of the project site (location 2), the facility would discharge from on- site (trust property) into an 

unnamed tributary to Windsor Creek that flows along the eastern boundary of the project site. As shown 

in Figure 5, Windsor Creek connects to Mark West Creek, which connects to the Russian River. 

Issuance of a NPDES permit is considered a separate federal action with the USEPA as the lead agency 

and the Tribe would be required to comply with all conditions of the permit.

STORM-WATER DRAINAGE SYSTEM

Surface runoff generally flows off-site to the east into an unnamed tributary to Windsor Creek and to the 

west into the Town of Windsor’s roadside stormwater drainage system. In either direction, surface flows 

from within the project site ultimately connect to the Russian River. The project site does not currently 

have a stormwater drainage system, given that it is undeveloped. However, a system will be designed for 

the proposed project and will be a component of project development. A stormwater drainage plan will 

be implemented that involves storm drain inlets, storm-water conveyance pipelines, vegetated swales and 

modern storm filter vaults, the use of additional bioretention measures to reduce the levels of 

sedimentation and contaminants in runoff waters, check dams, and a bio retention pond (Adobe 

Associates, 2010). Stormwater drainage within the project site would be accomplished such that off-site 

stormwater flows are maintained at rates that are consistent with the pre-existing conditions. 

1.3 INTERRELATED AND INTERDEPENDENT ACTIVITIES

Interrelated and interdependent activities are those that activities that occur as a result of the proposed 

project. These activities would not occur and would not be required without the proposed project and 

they do not have any independent utility on their own. However, interrelated and interdependent 

activities; if they occur, may result in impacts to biological resources and the effects of these activities can 

be direct or indirect. These impacts will be addressed in Section 7 of this BA. 

1.4 PURPOSE AND NEED

The Tribe’s purpose for taking the 124.12 acres of land into trust is for the development of a residential 

community, a community center, and associated Tribal facilities. The Lytton Tribe consists of 

approximately 270 Tribal members that are currently dispersed throughout Sonoma County and state and 

do not have an identifiable community of their own. The proposed acquisition would bring together 

Tribal members into a community by providing adequate housing and associated facilities to improve the 

quality of life of the Tribal members. Acceptance of the subject parcels into federal trust would assist the 

Tribe in meeting a long-term, viable, and sustainable solution to the Tribe’s lack of adequate housing and 

provide a place to congregate for governmental and social purposes.

2.0 SUMMARY OF CONSULTATION TO DATE 

The lead agency for the proposed project is the BIA. As such, this report will be submitted to the BIA as 

an attachment to the EA for the proposed project. To date, informal consultation (e.g., baseline research 

using the USFWS database queries for regionally occurring special-status species and personal phone 

communications between AES staff and resource agency staff) has occurred. The BIA formally requested 

Section 7 consultation on August 3, 2009 for the fee-to-trust process with the EA and BA released for 

public review in July 2009 for a smaller, 92-acre application with the same project components. A letter 

was submitted to the Sacramento USFWS office on February 10 and March 5, 2010 requesting a status 

update on the Section 7 consultation. Since these letters, the Tribe has purchased an additional 32.12 

acres contiguous to the original fee-to-trust property proposed for a revised site plan and alternatives, 

requiring this revised BA and EA (AES, 2011). 

3.0 REGULATORY SETTING 

This section summarizes the applicable federal regulations regarding biological resources within the 

project site. The regulatory context of the proposed project is derived from federal laws that govern the 
Biological Assessment 

Analytical Environmental Services 12 Lytton Residential Development

September 2010 Biological Assessment

protection of biological resources. The fundamental laws included within the scope of this BA are the 

FESA and the National Environmental Policy Act (NEPA). Other state and local laws such as the 

California Endangered Species Act (CESA), the California Fish and Game Code (including the Natural 

Communities Conservation Planning Act), the California Environmental Quality Act (CEQA), and 

relevant goals and policies within the Sonoma County General Plan (Sonoma County, 2008) are not 

addressed within this BA. 

FEDERAL ENDANGERED SPECIES ACT

The USFWS and NMFS implement the FESA (16 USC Section 1531 et seq.). Under the FESA, federally 

listed threatened and endangered species (50 CFR Section 17) are protected from take (defined as direct 

or indirect harm) unless a Section 10 incidental take permit is granted or a Section 7 consultation and a 

Biological Opinion (BO) with incidental take provisions is provided. Pursuant to the requirements of the 

FESA, agencies reviewing proposed projects within their jurisdictions must determine whether any 

federally listed species have the potential to occur within a proposed project site and if the proposed 

project would have any potentially significant impacts upon such species. Under the FESA, habitat loss 

is considered an impact to a listed species. In addition, these agencies are required to determine whether 

the project is likely to jeopardize the continued existence of any species proposed for listing under the 

FESA or result in the destruction or adverse modification of critical habitat proposed to be designated for 

such species (16 USC Section 1536 et seq.). Therefore, project-related impacts to these species, or their 

habitats, would be considered significant and require mitigation. The USFWS also maintains a list of 

candidate species, which are considered during environmental review, though they are not formally 

protected under the FESA. Candidate species may become proposed for official listing. 

SANTA ROSA PLAIN CONSERVATION STRATEGY

The USFWS, in cooperation with the USEPA, U.S. Army Corps of Engineers (USACE), California 

Department of Fish and Game (CDFG), North Coast Regional Water Quality Control Board (NCRWQCB), and other local jurisdictions and interests, has developed a strategy to conserve and contribute 

to the recovery of several federally listed species of the Santa Rosa Plain and their habitats. This 

document is titled The Santa Rosa Plain Conservation Strategy (Conservation Strategy) and identifies 

potential habitat and survey guidelines for the five listed species that are known to occur within the Santa 

Rosa Plain area that reaches from the City of Cotati north to the Town of Windsor and encompasses the 

project site (USFWS, 2005a). These species include the federally endangered California tiger salamander 

(CTS) (Ambystoma californiense), federally endangered Sonoma sunshine (Blennosperma bakeri), 

federally endangered Burke’s goldfields (Lasthenia burkei), federally endangered Sebastopol 

meadowfoam (Limnanthes vinculans), and federally endangered many-flowered navarretia (Navarretia 

leucocephala ssp. plieantha). 

The project site falls outside the known range of CTS (USFWS, 2005a); refer to Section 4.3. However, 

the project site is within the range of the four listed plant species that are known to occur on the Santa 

Rosa Plain. As such, determinant-level protocol surveys are required in accordance with the 
Biological Assessment 

Analytical Environmental Services 13 Lytton Residential Development

September 2010 Biological Assessment

Conservation Strategy. In order to substantiate negative findings for the four listed plant species, the 

Conservation Strategy requires a minimum of two years of negative protocol survey results for future 

permitted actions. The protocol requires that at least three separate floristic surveys be conducted during 

the duration of the growing season within the project site for two consecutive years and that each one of 

these three floristic surveys be conducted at a time when at least one of the four listed plant species is 

identifiable (i.e., blooming) at a local reference site. Should these criteria not be met, USFWS will 

assume presence for all four listed plant species. 

Additional information regarding permitting requirements is available in a Programmatic Consultation 

for USACE 404 Permitted Projects that May Affect Four Endangered Plant Species on the Santa Rosa 

Plain, California (File Number 223420N) (USFWS, 2007). USFWS requires mitigation for impacted 

aquatic features that constitute suitable habitat for the four listed plant species (i.e., wetland features that 

are not occupied by the four listed plant species) and the mitigation ratios vary according to whether or 

not presence of these plant species is documented, assumed, or substantiated-negative. By definition, 

suitable habitat for the four listed plant species includes suitable vegetative conditions in combination 

with specified topographic and hydrologic conditions. Vegetative conditions such as areas that support 

vernal pool indicator species and seasonal wetland areas where weedy grasses contribute less than 90 

percent of the relative vegetation cover must be present (CH2M Hill, 1998). These vegetative conditions 

must occur in combination with one or more topographic and hydrologic conditions: the wetland area has 

not been entirely filled such that the wetland no longer floods or ponds and the original topography no 

longer exists, the wetland has an outlet barrier or occurs in depressional terrain, or the wetland contains 

surface water during the rainy season in a normal rainfall year for seven or more consecutive days 

(CH2M Hill, 1998). 

WETLANDS AND OTHER WATERS OF THE U.S. 

Any project that involves the discharge of dredged or fill material in navigable and other waters of the 

U.S., including wetlands, must first obtain authorization from the USACE, under Section 404 of the 

CWA. The USACE also regulates activities in navigable waters of the U.S. under the Rivers and Harbors 

Act (Sections 9 and 10). Activities such as construction of any structures in or over navigable waters of 

the U.S., or other work that may affect the course, location, condition, or physical capacity of navigable 

waters may require a USACE permit. The USEPA, USFWS, NMFS, and several other agencies provide 

comments on USACE permit applications. The USACE has established a series of nationwide permits 

(NWP) that authorize certain activities in waters of the U.S. 

In addition, a Section 401 Water Quality Certification Permit was established to comply with CWA 

Sections 301, 302, 303, 306 and 307 and is regulated by the Regional Water Quality Control Board 

(RWQCB) except on federal property where the USEPA retains jurisdiction. When the subject site is, as 

proposed, taken into trust, the USEPA will be the 401 lead agency. Anyone that proposes to conduct a 

project that may result in a discharge to U.S. surface waters and/or “waters of the state” including 

wetlands (all types) year round and seasonal streams, lakes and all other surface waters would require a

federal permit or water quality certification. At a minimum, any beneficial uses lost must be replaced by 

a mitigation project of at least equal function, value and area. 

SONOMA COUNTY TREE ORDINANCE

State and local laws and ordinances addressing the protection of oaks and other trees are not applicable to 

trust lands, however, the standards and recommended requirements for tree preservation within the 

Sonoma County Tree Ordinance (Article 02: §26-02-140, Article 67: §26-67-005 through §26-67-050, 

and Article 88: §26-88-010 and §26-88-140) have been considered. The trees within the project site are 

not protected under federal law. The Sonoma County Code provides a level of protection for several 

native tree species, including: big leaf maple (Acer macrophyllum), black oak (Quercus kelloggii), blue 

oak (Quercus douglasii), coast live oak (Quercus agrifolia), interior live oak (Quercus wislizenii), 

madrone (Arbutus menziesii), oracle oak (Quercus morehus), Oregon oak (Quercus garryana), redwood 

(Sequoia sempervirens), valley oak (Quercus lobata), California bay (Umbellularia california), and their 

hybrids with diameter at breast height (DBH) greater than nine inches. In addition, the Sonoma County 

Tree Ordinance (Ordinance) mandates additional protection for valley oak trees and valley oak woodlands 

that occur within a designated Valley Oak Habitat (VOH) Combining District as defined in the Open 

Space and Resource Conservation Element in the Sonoma County General Plan 2020 (Policy OSRC-7m: 

Sonoma County, 2008). The Ordinance requires that valley oak trees within the VOH Combining District 

with single trunks over 20 inches DBH, or multiple trunks with cumulative DBH exceed 60 inches be 

preserved to the maximum extent feasible and replaced if preservation is not feasible. 

TERTIARY TREATED DISCHARGE

The proposed wastewater treatment facilities and surface water discharge points will be on trust land 

under the jurisdiction of the USEPA which will require a Region 9 issued NPDES permit. Although the 

jurisdiction and regulatory obligations fall under federal authority for this project the general basin plan 

water quality standards and beneficial use designations that have been established by the NCRWQCB 

would be adhered to under the regulatory authority of the EPA. The Regional Board has stated the ways 

in which surface water can be used, either directly or indirectly, by humans in addition to the dependence 

inherent to the environment use, are termed “beneficial uses.” Beneficial uses specific to water bodies 

within Sonoma County are identified within the Water Quality Control Plan, North Coast Region (Basin 

Plan; NCRWQCB, 2007). The Basin Plan identifies beneficial uses specific to the Guerneville and Mark 

West Creek Hydrologic Subareas of the Russian River Watershed. Each beneficial use requires different 

chemical or physical criteria for its protection. Water quality objectives for a particular water effluent 

source are geared to “the most sensitive use.” 

The following have been designated by the NCRWQCB (2007) as existing beneficial uses for the 

Guerneville* and Mark West Creek Hydrologic Subareas: 

• Municipal and Domestic Supply 

• Agricultural Supply 

• Industrial Service Supply 
Biological Assessment 

Analytical Environmental Services 15 Lytton Residential Development

• Groundwater Recharge 

• Freshwater Replenishment 

• Navigation 

• Water Contact Recreation 

• Non-Water Contact Recreation 

• Commercial and Sport Fishing 

• Warm Freshwater Habitat 

• Cold Freshwater Habitat 

• Wildlife Habitat 

• Rare, Threatened, or Endangered Species 

• Migration of Aquatic Organisms 

• Spawning, Reproduction, and/or Early Development 

• Estuarine*(Guerneville Subarea only) 

Additionally, the following have been identified by the NCRWQCB (2007) as potential beneficial uses 

for the Guerneville and Forsythe Creek Hydrologic Subareas: 

• Industrial Processes Supply 

• Hydropower Generation 

• Shellfish Harvesting 

• Aquaculture 

In order to prevent surface waters within the Russian River watershed from becoming effluent-dominated, 

the Basin Plan provides specific limitations to the timing of effluent discharges into surface waters of the 

watershed (NCRWQCB, 2007). Specifically, discharge of wastewaters is prohibited between May 15th

and September 30th, and during all periods when the wastewater discharge would be greater than one 

percent of the streamflow of the receiving water body. 

MIGRATORY BIRD TREATY ACT

Most bird species are protected under both federal and state regulations, especially those that are 

breeding, migratory, or of limited distribution. Under the Migratory Bird Treaty Act (MBTA) of 1918 

(16 USC Sections 703-712) federally listed (50 CFR Section 10), migratory bird species, their nests, and 

their eggs are protected from injury or death, and any project-related disturbances during the nesting 

cycle. As such, any potential project-related disturbances must be reduced or eliminated during the 

nesting cycle. 

BALD AND GOLDEN EAGLE PROTECTION ACT

The Bald Eagle Protection Act was originally enacted in 1940 to protect bald eagles and was later 

amended to include golden eagles (16 USC Subsection 668-668). This act prohibits the taking or 

possession of and commerce in bald and golden eagles, parts, feathers, nests, or eggs with limited 

exceptions. The definition of take includes pursue, shoot, shoot at, poison, wound, kill, capture, trap, 
Biological Assessment

collect, molest or disturb. Bald eagles may not be taken for any purpose unless a permit is issued prior to 

the taking. Activities which can be authorized by permit are: scientific collecting/research, exhibition, 

tribal religious, depredation, falconry, and the taking of inactive golden eagle nests, which interfere with 

resource development or recovery operations. The statute imposes criminal and civil sanctions as well as 

an enhanced penalty provision for subsequent offenses. 

MAGNUSON-STEVENS FISHERY CONSERVATION AND MANAGEMENT ACT

The Magnuson-Stevens Fishery Conservation and Management Act (MSFA) conserves and manages the 

fishery resources found off the coasts of the U.S., the anadromous species, and the Continental Shelf 

fishery resources of the United States, including the conservation and management of highly migratory 

species through the implementation and enforcement of international fishery agreements. The NMFS 

enforces the MSFA and regulates commercial and recreational fishing and the management of fisheries 

resources. The Sustainable Fisheries Act of 1996 amended the MSFA to include new fisheries 

conservation provisions by emphasizing the importance of fish habitat in regards to the overall 

productivity and sustainability of U.S. marine fisheries (Public Law 104-267). 

Under the MSFA, NMFS identifies, conserves, and enhances Essential Fish Habitat (EFH) for those 

species regulated under a federal Fisheries Management Plan (FMP). EFH is defined as “those waters 

and substrates necessary to fish for spawning, breeding, feeding, or growth to maturity.” The EFH 

Regulatory Guidelines (50 CFR 600.110) further interpret this definition as: 

• Waters include aquatic areas and their associated physical, chemical, and biological properties 

that are used by fish and may include aquatic areas historically used by fish where appropriate. 

• Substrate includes sediment, hard bottom, structures underlying the waters, and associated 

biological communities. 

• Necessary means the habitat required to support a sustainable fishery and the managed species’ 

contribution to a healthy ecosystem. 

• “Spawning, breeding, feeding, or growth to maturity” covers a species’ full life cycle. 

Federal agencies are required to consult with NMFS on all actions or proposed actions authorized, 

funded, or undertaken by the agency, which may adversely affect EFH (MSFA 305.b.2). Adverse affects 

are any impacts that reduce the quality and/or quantity of EFH. Adverse affects can include direct (e.g., 

contamination or physical disruption), indirect (e.g., loss of prey or reduction in species fecundity), sitespecific or habitat-wide impacts, including individual, cumulative, or synergistic consequences of actions 

(50 CFR 600.810). 

There are four FMPs in California, Oregon, and Washington that identify EFH for groundfish, coastal 

pelagic species, Pacific salmon, and Pacific highly migratory fisheries. The Pacific Coast groundfish 

FMP manages over 82 species (e.g., rockfish, sablefish, flatfish, and Pacific whiting). Species considered 

pursuant under this FMP often, though not exclusively, occur on or near the ocean floor or other 
Biological Assessment 

Analytical Environmental Services 17 Lytton Residential Development

September 2010 Biological Assessment

structures. The coastal pelagic species FMP manages finfish such as sardine, mackerel, anchovy, and the 

market squid. Species addressed in this FMP tend to occur nearer to the surface and EFH for these 

species is based on temperature range, life history cycles, and geographic distributions of these species. 

The Pacific salmon FMP includes both marine and freshwater EFH because of the unique biology of these 

species. As such, lakes, rivers, streams, ponds, wetlands, and other bodies of water that were historically 

accessible to salmon are considered EFH, including certain areas above artificial barriers. The FMP for 

highly migratory species manages mobile fishes such as tuna, swordfish, and sharks. EFH identified in 

this FMP is typically is defined in terms of area, depth, temperature, salinity, oxygen levels, currents, and 

topography. 

4.0 METHODOLOGY 

For the purposes of this BA, the action area is the Lytton Residential Development Project site and 

immediately surrounding vicinity (i.e., roadways). The action area is defined as and solely includes the 

terrestrial and aquatic habitats within the project boundary and adjacent roadways. As mentioned in 

Section 1.2, the footprint of Alternative B was analyzed for the scope of this document because it has the 

maximum build-out of any of the proposed alternatives. However, Alternative A is the preferred 

alternative. If Alternative B is ultimately chosen, an NPDES permit would be required to permit effluent 

wastewater discharges under the strict NCRWQCB Basin Plan requirements. This action would be 

authorized under the jurisdictional authority of USEPA Region 9. On trust lands, this is a separate federal 

action by the USEPA. 

4.1 PRELIMINARY RESEARCH

Prior to conducting the field surveys AES biologists reviewed the following resources: 

• Aerial photographs of the project site; 

• USGS “Healdsburg, California” 7.5-minute topographic quadrangle (USGS, 1993); 

• Online Soil Survey of Sonoma County, California (NRCS, 2010); 

• A USFWS list of federally listed special-status species with potential to occur within 

Sonoma County and the “Healdsburg, California” 7.5-minute topographic quadrangle 

and the eight surrounding quadrangles (“Jimtown,” “Mount Saint Helena,” “Mark West 

Springs,” “Santa Rosa,” “Sebastopol,” “Camp Meeker,” “Guerneville,” and 

“Geyserville”) (USFWS, 2009; query date December 24, 2009); 

• A California Natural Diversity Database (CNDDB) list of state and federally listed 

special-status species with potential to occur within the “Healdsburg, California” 7.5-

minute topographic quadrangle and the surrounding eight quadrangles (CDFG, 2003; 

query date December 24, 2009); 

• A CNDDB map of state and federally listed special-status species that have been 

documented within a five-mile radius of the project site (CDFG, 2003; mapped June 

2010);

• A California Native Plant Society (CNPS) list of special-status plant species with 

potential to occur within the “Healdsburg, California” 7.5-minute topographic 

quadrangle and the surrounding eight quadrangles (CNPS, 2009; query date December 

24, 2009); and 

• A query of the CDFG Anadromous Fish Passage Database (CDFG, 2010). 

The USFWS, CNDDB, and CNPS research lists of regionally occurring special-status species are 

included for reference purposes in Attachment A. The CNDDB five-mile radius map is included as 

Figure 6. 

4.2 FIELD SURVEYS AND ANALYSIS

AES staff has conducted approximately 346 observer-hours of biological field surveys throughout the 

project site. These surveys were conducted various months over the period of four years (Table 2). The 

surveys were conducted on foot and the entire project site has been evaluated extensively. During the 

surveys, the habitat types on-site were classified and further evaluated for the occurrence of and the 

overall potential to support special-status plant and animal species. Habitat classification was based on 

the systems presented in A Manual of California Vegetation (MCV) (Sawyer et al., 2009), Preliminary 

Descriptions of the Terrestrial Communities of California (Holland, 1986), and A Guide to Wildlife 

Habitats of California (Mayer and Laudenslayer, Jr., 1988), but have been modified to reflect the existing 

site conditions. 

All visible plant and wildlife species were noted and identified to the lowest possible taxonomic level, 

which is required for accurate identification and reporting. All tracks, scat, etc. observed on-site were 

also noted. Plant species identification, nomenclature, and taxonomy followed The Jepson Manual: 

Higher Plants of California (Hickman, 1993) and A Flora of Sonoma County (Best et al., 1996). Wildlife 

identification, nomenclature, and taxonomy followed standard reference texts including: Sibley Field 

Guide to Birds of Western North America (Sibley, 2003), Field Guide to Western Reptiles and 

Amphibians (Stebbins, 2003), and Mammals of North America (Reid, 2006) and Mammals of California

(Jameson and Peeters, 2004). 

A complete list of all of the regionally occurring special-status species reported in the scientific database 

queries was compiled for the project site (Attachment B). An analysis to determine which of these 

special-status species have the potential to occur within the project site was conducted. The habitat 

requirements for each regionally occurring special-status species were assessed and compared to the type 

and quality of habitats observed on-site during the field surveys. Several regionally occurring specialstatus species were eliminated due to lack of suitable habitat within the project site, elevation range, lack 

of suitable soil/substrate, and/or distribution. The analysis was also based on reviews of resource agency 

materials, pertinent scientific literature, aerial photography of the project site, topographic maps of the 

project site, and other local information, as well as, field work by AES biologists and botanists.

The floristic survey efforts were conducted according to the Conservation Strategy Protocol (USFWS, 

2005a) and occurred within the appropriate bloom periods for all potentially occurring special-status plant 

species. A more explicit description of the methodology and results of the floristic surveys that have been 

conducted within the project site to date is included in the Technical Botanical Memorandum 

(Attachment E). One additional year of protocol level surveys is required for some of the more recently 

acquired parcels. An update to the Technical Botanical Memorandum will be completed following these 

surveys. 

A general examination of the project site was conducted to assess the overall distribution, density, and

structure of native trees on site. A detailed arborist assessment was conducted within a selected subset 

area of the project site and the portions that are located within the VOH Combining District. Following 

this assessment, data was evaluated and an analysis conducted to extrapolate the total numbers of trees 

within the project site and their approximate sizes. In addition, the entire project site was surveyed for 

exceptional (i.e., heritage) trees and specifically surveyed the riparian corridor along the eastern boundary 

of the site. A large subset area near the center of the project site was selected for detailed surveys. This 

subset area was chosen because it has a high density of trees and is a suitable representation of tree 

distribution within the remainder of the project site. Arbor surveys were conducted on March 3, 4, and 5, 

October 16 and 17, December 3, 2008, and a subsequent survey was conducted on March 11, 2009. 

Within the selected subset survey area, a comprehensive tree inventory of all trees that were greater than 

nine inches DBH was performed, as recommended in the Sonoma County Ordinance. Each of these trees 

was marked with a numbered aluminum tag and the location was mapped in the field using a handheld 

global positioning system (GPS) unit with sub-meter accuracy (Trimble GeoXT). Tree species 

identification, nomenclature, and taxonomy followed The Jepson Manual: Higher Plants of California

(Hickman, 1993). AES staff also collected a limited amount of arbor survey data for trees along the 

eastern and western project boundaries, within riparian areas, and along proposed roadways. Results of 

the arborist survey and analysis are detailed in the Arborist Report (AES, 2010b). 

To analyze the proposed discharge points in support of the potential NPDES requirements, AES 

biologists conducted a stream characterization of both the unnamed drainage channel described for 

wastewater location 1 and the unnamed tributary to Windsor Creek described for location 2 (AES, 

2010d). Data regarding the ambient physical and biological conditions of these stream channels was 

gathered on and within the vicinity of the project site. This allows for an evaluation of the potential 

impacts to downstream beneficial uses resultant from proposed effluent discharges. The unnamed 

tributary to Windsor Creek was assessed using the RWQCB Surface Water Ambient Monitoring Program 

Bioassessment Procedures (Ode, 2007). These methods were modified to reflect channel conditions 

during the assessment of the unnamed drainage channel on the northwestern corner of the project site 

(proposed WTRF location 1). 

4.3 FEDERALLY LISTED SPECIES

For the purposes of this assessment, special-status has been defined to include those species that are listed 

as endangered or threatened under the FESA (or formally proposed and/or candidates for listing). While 

other state and/or CNPS-listed species may have potential to occur within the project site and its vicinity 

(and have been included in the baseline research that was conducted for the Proposed Project), these 

species generally receive no specific protection on Tribal trust land and are not necessarily afforded 

protection by the FESA. 

Six federal special-status plant species were determined to have potential to occur within the project site 

and are addressed within this BA (Attachments B and E). Species determined to have no potential to 
Biological Assessment 

Analytical Environmental Services 22 Lytton Residential Development

occur within the project site are not further discussed within this document. The federally listed plant 

species determined to have potential to occur on-site include: 

• Sonoma alopecurus (Alopecurus aequalis var. sonomensis), 

• Sonoma sunshine (Blennosperma bakeri), 

• Burke’s goldfields (Lasthenia burkei), 

• Pitkin Marsh lily (Lilium pardalinum ssp. pitkinense) 

• Sebastopol meadowfoam (Limnanthes vinculans), and 

• Many-flowered navarretia (Navarretia leucocephala ssp. plieantha). 

No federal special-status animal species were found to have potential to occur within the project site, 

including California Tiger Salamander. The project site falls outside the known range of the salamander 

(USFWS, 2005a) and no suitable habitat occurs within the project site for this species (Attachment B). 

The name, regulatory status, distribution, habitat requirements, and period of identification for the federal 

special-status plants determined to have potential to occur on-site are identified in Table 3.

4.4 OTHER SPECIES

An additional 19 non-federal special-status species (state or CNPS listed) were identified as having 

potential to occur within the project site (Table 4). Of these, fourteen are CNPS list 1B through 4.3 

plants, and five are animal species. Only two plant species (both CNPS list 4.2 species) are known from 

four years of surveys of the project site: Harlequin lotus (Lotus formosissimus) and Lobb’s aquatic 

buttercup (Ranunculus lobbii). These two species were found during plant surveys predating 2010 within 

wetlands that will be avoided by project design (Attachment E). No other non-federal special-status 

species have been observed within the project site during field surveys encompassing 2007-2010.

5.0 CRITICAL HABITAT 

Critical habitat is defined in Section 3 of the FESA as (i) the specific areas within the geographical area 

occupied by a species, at the time it is listed in accordance with the Act, on which are found those 

physical and biological features (I) essential to the conservation of the species and (II) that may require 

special management considerations or protection; and (ii) specific areas outside the geographical area 

occupied by the species at the time it is listed, upon a determination that such areas are essential for the 

conservation of the species (16 USC Section 1531 et seq.). Critical habitat for the central California coast 

steelhead (Oncorhynchus mykiss irideus) ecological significant unit (ESU) was designated in 2005 within 

Windsor Creek, approximately 1.5 miles south of the project site. Critical habitat for the central 

California coastal Chinook salmon (Oncorhynchus tswawytscha) ecological significant unit (ESU) was 

designated in 2005 within the Russian River, approximately 1.5 miles west of the project site 

(Attachment B). Other designated critical habitats occur further from the project site and are discussed 

in greater detail in Attachment B. Critical habitat has not yet been designated for Sonoma alopecurus, 

Sonoma sunshine, Burke’s goldfield’s, Pitkin Marsh lily, Sebastopol meadowfoam, or many-flowered 

navarretia. However Sonoma sunshine, Burke’s goldfield, Sebastopol meadowfoam and many-flowered 

navarretia are covered by the Santa Rosa Plain Conservation Strategy (USFWS, 2005a). 

6.0 RESULTS 

6.1 ENVIRONMENTAL SETTING

The project site is located in central Sonoma County, within the Russian River Valley. Sonoma County 

has a Mediterranean climate regime characterized by hot, dry, sunny summers and cool, rainy winters. 
Biological Assessment 

Analytical Environmental Services 27 Lytton Residential Development

Offshore winds and fog from the Pacific Ocean are common and these factors tend to moderate the 

climate in Sonoma County. Evening temperatures are frequently much cooler than midday temperatures 

and mornings are prone to coastal fog. The mean annual temperature range near the Town of Healdsburg 

is approximately 46° to 74° Fahrenheit (F). The average annual precipitation near the Town of 

Healdsburg is approximately 42 inches, with a maximum of approximately 8.81 inches during the month 

of January. This climate data was collected from 1931 to 2007 (WRCC, 2007). 

The project site is composed of gently rolling terrain and is situated at elevations that range from 

approximately 95 feet to 220 feet (29 to 67 meters) above mean sea level. An unnamed tributary to 

Windsor Creek is located along the eastern boundary and the Russian River is located approximately 

1,071 meters (3,515 feet) west of the project site. The Russian River Valley falls within climate Zone 14 

“Ocean-influenced Northern and Central California.” Climate Zone 14 includes inland areas with oceanic 

or other cold air influence. This climate zone is a linear region that runs from Humboldt County to Santa 

Barbara County. The local and regional geology is within the Outer North Coast Range (NCoRO) 

geomorphic province, and is characterized by redwood, mixed-evergreen, and mixed-hardwood forests 

and by very high rainfall. This geomorphic province occurs within the greater California Floristic 

Province (Ca-FP), thus is equivalent to “cismontane” as often cited in other scientific texts (Hickman, 

1993). 

The project site is situated in a rural residential/agricultural setting near the Town of Windsor, 

approximately one mile west of the town center. APNs 066-191-017, 066-191-018, 066-191-022, 066-

050-040 and 066-050-047, which comprise approximately 41.23 acres of the project site, are within the 

sphere of influence of the Town of Windsor (Table 1). APN 066-050-047 is the only parcel within the 

Town of Windsor limits. Specific surrounding land uses include rural residences, agriculture (vineyards 

and pastures), and undeveloped parcels. The project site is predominantly undeveloped and uncultivated. 

However, several abandoned and/or occupied residences and associated structures are located on-site. 

Twelve existing residences and other associated buildings are located within APNs 066-300-033, 066-

300-028, 066-191-020, 066-191-017, 066-300-023, 066-300-017, 066-191-016, 066-191-019, 066-191-

021 and 066-050-040. 

6.2 SOILS

According to the U.S. Department of Agriculture (USDA), Natural Resources Conservation Service 

(NRCS) online Soil Survey for Sonoma County, seven soil units, or types, have been mapped within the 

project site (NRCS/USDA, 2010). These include: (AeA) Alluvial Land, clayey; (AgE) Arbuckle gravelly 

sandy loam, 15 to 30 percent slopes; (Cgc) Clough gravelly loam, 2 to 9 percent slopes; (FaD) Felta very 

gravelly loam, 5 to 15 percent slopes; (FaF) Felta very gravelly loam, 30 to 50 percent slopes; (HtC) 

Huichica loam, 2 to 9 percent slopes; and (SkD) Spreckels loam, 9 to 15 percent slopes. A map that 

illustrates the extent of the soil types within the project site is provided as Figure 7. (AeA) Alluvial

6.3 HABITAT TYPES

Potential to Occur On-site: The project site contains a variety of terrestrial and aquatic habitat types. 

Six terrestrial habitats were identified on-site including: mixed oak woodland, oak savannah, annual 

grassland, mixed riparian, pasture, and ruderal/developed. Six aquatic habitat types were observed on-site 

including: seasonal wetland, seasonal wetland swale, stock pond, isolated pit, perennial stream and 

ephemeral drainage. A summary of the terrestrial and aquatic habitat types identified within the project 

site and the approximate acreages of each type is provided in Table 5. A map that illustrates the 

terrestrial and aquatic habitat types within the project site is presented as Figure 8. Representative 

photographs of terrestrial habitats are provided in Figure 9.

TERRESTRIAL HABITATS

ANNUAL GRASSLAND

Approximately 5.48 acres of annual grassland habitat was mapped within the project site, which 

represents 4.41 percent of all habitat types (Table 5, Figure 8). Annual grassland habitat is scattered in 

small patches throughout the mixed oak woodland and oak savannah habitats on the project site, as well 

as a grassy hillside within APN 066-300-023 of approximately one acre. Trees are largely absent within 

this community type and it is generally dominated by non-native annual grasses and forbs. Native

grasses found commonly in these areas included California oatgrass (Danthonia californica), blue wildrye 

(Elymus glaucus), and purple needlegrass (Nassella pulchra). Non-native grasses common within this 

habitat type included vernal grass (Anthoxanthum aristatum), wild oat (Avena fatua), quaking grass 

(Briza maxima), hedgehog dog-tail grass (Cynosurus echinatus), annual rabbit-foot grass (Polypogon 

monspeliensis), small patches of medusa-head grass (Taeniatherum caput-medusae), and rat-tail vulpia 

(Vulpia myuros). Non-native brome grasses (Bromus spp.) were notably uncommon in these areas. 

Native forbs commonly observed were harvest brodiaea (Brodiaea elegans), soap plant (Chlorogalum 

pomeridianum var. pomeridianum), blue dicks (Dichelostemma capitatum), plantain (Plantago erecta), 

mule’s ears (Wyethia glabra), Ithuriel’s spear (Triteleia laxa), sun cup (Camissonia ovata), buttercup 

(Ranunculus californicus) and butter and eggs (Triphysaria eriantha). Non-native forbs commonly 

observed were bur chervil (Anthriscus caucalis), filaree (Erodium botrys), Klamath weed (Hypericum 

perforatum), sanicle (Sanicula crassicaulis), common sow thistle (Sonchus oleraceous), torilis (Torilis 

arvensis), and vetch species (Vicia sativa and V. villosa). 

MIXED OAK WOODLAND

Mixed oak woodland is the dominant habitat type within the project site. Approximately 53.59 acres of 

mixed oak woodland habitat was mapped within the project site, which represents 43.14 percent (Table 4, 

Figure 8). The overstory of this community is composed of mature blue oak (Quercus douglasii), black 

oak (Quercus kellogii), coast live oak (Quercus agrifolia), and madrone (Arbutus menziesii) trees. More 

specifically, Black Oak Forest Alliance (Sawyer et al., 2009) is found on ridgetops and slopes in the 

northwest quadrant of APN 066-300-031, as well as APNs 066-300-033 and 066-300-028. The Black 

Oak Forest Alliance is dominated by black oak (> 50 percent) in the canopy, with madrone and coast live 

oak as subdominants. Non-riparian woodlands elsewhere on the project site are Blue Oak Woodland 

Alliance (Sawyer et al., 2009), where blue oak is dominant (> 50 percent) in the tree canopy, with coast 

live oak subdominant. Shrub and vine species observed within the oak woodlands on the project site 

include: poison oak (Toxicodendron diversilobum), Himalayan blackberry (Rubus armeniacus), coyote 

brush (Baccharis pilularis), scotch broom (Cytisus scoparius), pipevine (Aristolochia californica), and 

honeysuckle (Lonicera hispidula). The understory of this community is dominated by annual grasses and 

forbs, observed species included annual vernal grass, wild oat, quaking grass, hedgehog dog-tail grass, 

soap plant, filaree, Klamath weed, skunkweed (Navarretia squarrosa), blue-eyed grass (Sisyrinchium 

bellum), torilis, rose clover (Trifolium hirtum), and bird’s beak (Cordylanthus pilosus). The majority of 

the woodland stands within the mixed oak woodland habitat consist of a monoculture of trees that appear 

to have become established within the same time period. The woodland stands on site are dense with 

overcrowding, competition, and a majority of specimens with multiple suppressed boles from an arborist 

standpoint. Several stands of oak trees have dead limbs, higher rates of disease, insect infestation, 

parasites, build-up of woody debris (i.e., fuel), and a thick, jagged, and impenetrable overstory. In 

general, the oak woodlands in the project site have relatively high fuel build-up, and the density of trees 

and fuels pose a potential fire threat.

Analytical Environmental Services 33 Lytton Residential Development

September 2010 Biological Assessment

OAK SAVANNAH

Approximately 8.21 acres of oak savannah habitat was mapped within the project site, which represents 

6.61 percent (Table 5, Figure 8). The mixed oak savannah habitat type within the project site is very 

similar to the mixed oak woodland habitat type, except for the density of trees. The mixed oak savannah 

habitat type is composed of fewer trees and they are spaced at much greater distances. The plant species 

composition is the same as described for mixed oak woodland above, with the exception of the shrub/vine 

layer. The shrub/vine stratum is largely absent within this community. 

MIXED RIPARIAN

Approximately 1.56 acres of mixed riparian habitat was mapped within the project site, which represents 

1.26 percent (Table 5, Figure 8). Mixed riparian habitat occurs along several of the drainages that were 

mapped within the project site. Plant species observed in the tree layer of this community include Valley 

oak (Quercus lobata), willows (Salix spp.), and Fremont’s cottonwood (Populus fremontii). The 

dominant plant species observed within the shrub/vine layer of this community are Himalayan blackberry 

and poison oak. Other plant species observed within the herbaceous layer of this community include: 

ryegrass, little quaking grass (Briza minor), and blue wild-rye. 

PASTURE

Pasture and developed areas dominate the eastern portion of the project site. Approximately 36.78 acres 

of pasture habitat occurs within the southeastern region of the project site, which represents 29.61 percent 

(Table 5, Figure 8). Pasture south of Windsor River Road appears to be used primarily for horses, and 

pasture north of Windsor Road has been used primarily for cattle in recent years. Trees and shrubs are 

sparse within this community, although, remnant stands of blue oak woodland persist and there are a few 

stands of planted ornamental shade trees. Pasture differs from annual grassland habitat in overall plant 

species composition and the distribution of native species, which reflects more intensive management 

through periodic plowing and seeding. Occasional natives observed on-site included California oatgrass 

and purple needlegrass in pastures on the north side of Windsor River Road. Pastures on the south side of 

Windsor River Road contained a greater cover of weedy forbs and non-native grasses. Dominant nonnative grasses included: wild oat, quaking grass, ripgut brome, soft brome, barley (Hordeum murinum), 

ryegrass, medusa-head grass, and rat-tail vulpia. Non-native forbs that were common in the pasture 

included filaree, bur chervil, torilis, prickly sow thistle (Sonchus asper), Shamrock clover (Trifolium 

dubium), rose clover, vicia species, pineapple weed (Chamomilla suaveolens), field mustard (Brassica 

rapa), black mustard (Brassica nigra), Shepard’s purse (Capsella bursa-pastoris), bindweed/morning 

glory (Convolvulus arvensis), cut-leaved geranium (Geranium dissectum), shortpod mustard (Hirschfeldia 

incana), perennial/rough cat’s ear (Hypochaeris radicata), Spanish clover (Lotus purshianus), yellow 

wild radish (Raphanus raphanistrum) and sheep sorrel (Rumex acetosella). The following native forbs 

observed within pasture habitat include: soap plant, buttercup, sun cup, butter and eggs, dove weed 

(Eremocarpus setigerus), bicolored lupine (Lupinus bicolor), and bracted popcorn flower (Plagiobothrys 

bracteatus).

RUDERAL/DEVELOPED

Approximately 16.99 acres of ruderal/developed habitat was mapped within the project site, which 

represents 13.68 percent (Table 5, Figure 8). The areas classified as ruderal/developed habitat within the 

project site include all existing residences and structures, any landscaped areas, roads and parking areas, 

and otherwise disturbed regions. Non-native landscape plants observed in these areas included English 

walnut (Juglans regia), London plane tree (Platanus x acerifolia), Eucalyptus (Eucalytpus species), fig 

(Ficus carica), pomegranate (Punica granatum), apple (Malus species), plum (Prunus species), heavenly 

bamboo (Nandina domestica), periwinkle (Vinca major), and English ivy (Hedera helix). Weedy forbs 

observed within this habitat type included non-native sweet fennel (Foeniculum vulgare), mayweed 

(Anthemis cotula), bindweed, bristly oxtongue (Picris echioides), shortpod mustard, bur clover (Medicago 

polymorpha), filaree, English plantain (Plantago lanceolata), prostrate knotweed (Polygonum 

arenastrum), ripgut brome, wild oat, harding grass (Phalaris aquatica) and various lawn grasses. 

AQUATIC HABITATS

AES staff conducted a formal wetland delineation within the project site (AES, 2010a). A total of 1.6 

acres of potential waters of the U.S. were mapped within the 124.12 acres comprising the project site. Six 

aquatic feature types that were identified on-site include: seasonal wetland, seasonal wetland swale, stock 

pond, isolated pit, perennial drainage and ephemeral drainage (Table 5). Representative photographs of 

aquatic habitats are provided in Figure 10. The wetland delineation map is provided in Figure 11. A 

discussion of the wetlands and other waters mapped on-site is presented below. 

EPHEMERAL DRAINAGE

Ephemeral drainages are linear features that exhibit an OHWM and have a clearly defined bed and bank. 

They are seasonal features that typically convey rainwater and surface runoff flows seasonally and for 

short time periods. The channels within ephemeral drainages tend to be largely unvegetated due to the 

scouring effects of flowing water. If plants do occur within ephemeral drainages, they tend to occur 

within the upper limits of the drainage or in areas where sediment has deposited that can function as a 

plant substrate. Unlike intermittent drainages, ephemeral drainages are not typically influenced by 

groundwater. Nine ephemeral drainages were mapped within the project site for a total of 0.379 acre or 

8,270.18 linear feet (AES, 2010a). This habitat type comprises approximately 0.31 percent of the habitats 

on-site. Plant species observed within these feature types include: blue oak, coast live oak, madrone, 

ryegrass, torilis, shortpod mustard, sedge (Carex densa), tall flatsedge (Cyperus eragrostis), poverty rush 

(Juncus tenuis), pennyroyal (Mentha pulegium), fiddle dock (Rumex pulcher), and hedge nettle (Stachys 

ajugoides). 

ISOLATED PIT

The isolated pits within the project site are relatively deep holes that were excavated within uplands. 

These features are round to rectangular in shape and the excavated dirt from within them is piled right 

beside them. Two isolated pits (approximately 0.022 acre) were mapped within the project site (AES,

2010a). This habitat type comprises approximately 0.02 percent of the habitats on-site. The two isolated 

pits may have functioned as watering holes for cattle, test percolation pits, or potential sites for trash 

disposal. Creeping spikerush (Eleocharis macrostachya) was the dominant plant species observed within 

the isolated ponds on-site. 

SEASONAL WETLAND

Seasonal wetlands are typically closed, depressional features that are ephemerally wet due to the 

accumulation of surface runoff and rainwater collection within low-lying areas. The length of inundation 

tends to be relatively short and seasonal wetlands are typically dominated by non-native, hydrophytic 

plant species. Seven seasonal wetlands (approximately 0.624 acres) were mapped within the project site 

(AES, 2010a). This habitat type comprises approximately 0.5 percent of the habitats on-site. Plant 

species observed within the seasonal wetlands included blue oak, ryegrass, fiddle dock, quaking grass, 

poverty rush, hedgehog dog-tail grass, pennyroyal, tall flatsedge, Bermuda grass (Cynodon dactylon), 

annual vernal grass, curly dock (Rumex crispus), soft brome, Mediterranean barley, white water buttercup 

(Ranunculus aquatilis), and little quaking grass. 

SEASONAL WETLAND SWALE

Seasonal wetland swales are typically linear-shaped features that lack a clearly defined bed and bank and 

do not exhibit an OHWM. The length of inundation within seasonal wetland swales is relatively short 

and seasonal. These features primarily carry surface runoff and rainwater from areas of higher elevation 

to areas of lower elevation. Three seasonal wetland swales (approximately 0.273 acres) were mapped 

within the project site (AES, 2010a). This habitat type comprises approximately 0.22 percent of the 

habitats on-site. Plant species observed within the seasonal wetland swale mapped within the project site 

include: valley oak, pennyroyal, tall flatsedge, ryegrass, cut leaved geranium, and curly dock. 

STOCK POND

Stock ponds are typically man-made pond features which usually have a clearly defined bed and bank and 

OHWM. Two stock ponds (approximately 0.266 acre) occur within the northern two parcels of the 

project site (AES, 2010a). This habitat type comprises approximately 0.21 percent of the habitats on-site. 

Dominant plant species observed within the stock ponds include spikerush and semaphore grass 

(Pleuropogon californicus); rye grass and wild oats were dominant along upland slopes. 

PERENNIAL DRAINAGE

Perennial drainages are linear features that exhibit an OHWM, have a clearly defined bed and bank, are 

typically inundated year-round, and have some degree of ground water contribution. A single perennial 

drainage (approximately 0.036 acre) was observed within the project site along the eastern boundary 

(AES, 2010a). This habitat type comprises approximately 0.03 percent of the habitats on-site. This 

feature is an unnamed tributary to Windsor Creek and is shown as a blue-line stream on the “Healdsburg, 

CA” USGS quad (Figure 2). Plant species observed within the riparian corridor associated with the

perennial drainage on-site include Valley oak, blue oak, black oak, willows, Himalayan blackberry and 

poison oak. Plant species were largely absent within the actual channel due to the scouring effect of 

flowing water. A representative photograph of a perennial drainage is shown in Figure 10, Photo 1.

6.3.1 POTENTIAL IMPACTS AND RECOMMENDED MITIGATION

Potential Impacts: The proposed project is likely to result in direct and/or indirect impacts (i.e., 

development) to the annual grassland, mixed oak woodland, oak savannah, ruderal/ developed, pasture 

and mixed riparian habitats onsite. Of these habitat types, oak woodland, oak savannah, and mixed 

riparian are generally considered sensitive. Potential impacts to terrestrial and aquatic habitats by each 

project alternative are provided in Table 6 below. To the maximum extent possible, the proposed project 

has incorporated the mixed oak woodland, oak savannah, and riparian woodland habitats into the site 

design to minimize impacts to these habitats by adjusting the locations of lots and structures, utilize 

existing roadways and cleared areas to avoid more pristine stands of woodlands and exceptionally large 

individual trees (heritage trees), maintain woodland corridors, and establish aesthetic woodland buffer 

regions around development areas. Potential impacts to these habitats (i.e., woodlands) are more 

specifically addressed below.

Under the Alternative B, approximately 11.75 and 42.1 acres of land would be required for irrigation of 

treated wastewater under the 100-year precipitation event (worst case scenario) under the first and second 

options for Alternative B, respectively. During years of average rainfall, the amount of land required for 

irrigation would be much lower. Areas proposed for irrigation include landscaped areas such as parks, 

yards, and residential and communal structure landscaping. Additional irrigation areas include 

approximately 14 acres within the two parcels north of Windsor River Road (Figure 4). The irrigation of 

landscaped areas would have no impact on habitats. However, irrigation of the currently unirrigated

pasture north of Windsor River Road could cause a shift in the species composition of this area. 

Irrigation could lead to higher concentrations of non-native species within irrigated areas, which could be 

a benefit to some species and a detriment to others. Since the habitats within the project site are common 

throughout the region, irrigation in the project site would not constitute a significant impact.

Recommended Mitigation Measure(s): Impacts to sensitive habitats have been minimized to the extent 

feasible. Impacts to terrestrial habitats considered sensitive such as mixed riparian and mixed oak 

woodland and oak savannah do not exceed one third of the total habitat acreage within the project site. 

In addition, there is no federal requirement for mitigation of impacts to these habitat types. Project design 

incorporates avoidance and setbacks from mixed riparian habitat as well as identified wetlands and 

drainages, therefore impacts to aquatic habitats have been minimized to the extent feasible. For all other 

wetlands identified onsite the requirements as outlined in the 2007 Santa Rosa Plain Programmatic 

Biological Opinion issued by the Service have been adhered to, while the avoidance, minimization and 

mitigation of impacts will be consistent with this guidance as well as the guidance provided by the U.S. 

Army Corps of Engineers with regards to the fill of wetlands under Sections 404 and 401 of the CWA. 

Therefore, in accordance with these requirements, impacts to wetlands will be reduced to less than 

significant. 

6.4 NATIVE TREES

Potential to Occur On-site: Upon completion of focused arbor surveys within the subset area where 584 

trees were intensively surveyed and tagged, the remainder of the project site was divided into 200 foot by 

200 foot quadrates (AES, 2010b). In each quadrate, the general density class, species composition, and 

the number of trees over nine inches DBH was estimated. Each of the quadrates was assigned a general 

density class score ranging from one to four based on field reconnaissance and interpretation of aerial 

photography. The species composition data from the subset trees was extrapolated by density class across 

the project site to estimate an approximate number of trees within each quadrate with DBH greater than 

nine inches for each quadrate. With this information, the total number of trees, species composition, and 

size in each of the quadrates within the project site were estimated. The total number of trees within the 

entire project site was then estimated. A total of 4,528 trees with DBH greater than nine inches are 

estimated to be within the project site. The species composition of the trees on-site includes: black oak, 

blue oak, coast live oak, valley oak, and madrone. Approximately 32 heritage trees were identified 

throughout the project site (AES, 2010b). 

6.4.1 POTENTIAL IMPACTS AND RECOMMENDED MITIGATION

Potential Impacts: The proposed project has the potential to result in direct impacts (i.e., removal or 

damage) to oak and other native trees within the sensitive mixed oak woodland and oak savannah habitats 

onsite. Heritage trees, which were defined for this project as those trees comprised of at least a single 

bole that measures greater than 33 inches DBH, were mapped throughout the property. This size was 

chosen based on the Sonoma County ordinance, which assigns the greatest weighted value to trees with 
Biological Assessment

33 inches DBH (or greater) when evaluating impacts. The total number of trees that would be impacted 

by each project alternative was estimated by overlaying each alternative over the 200 foot grid and the 

total number of trees potentially impacted was then calculated. Table 7 estimates the total number of 

trees greater than nine inches DBH that would be directly impacted by each of the project alternatives, as 

well as the number and percentage of trees that would be preserved. No more than 37 percent of trees 

exceeding nine inches DBH would be impacted from development of the proposed project. The majority 

of the identified valley oaks within the VOH Combining District would be preserved owing to project 

design and avoidance of these trees. The development of the proposed project would preserve large, 

existing blocks of mixed oak woodland, particularly along sensitive areas of drainages and wetlands.

Recommended Mitigation Measure(s): Trees of notable size (i.e., exceeding 33 inches diameter at 

breast height) should be preserved to the greatest extent feasible. Impacts to valley oak trees within the 

Valley Oak Habitat Combining District will be avoided to the maximum extent feasible owing to project 

design. Protection of tree crowns and root zones shall be required for all trees planned for retention in the 

vicinity of the construction footprint. Mitigation is recommended to replace native oak trees permanently 

removed as a result of project construction at a 1:1 ratio, or alternatively, preserve an equivalent area of 

oak woodland. Replacement oak trees should be planted on Tribally-owned land and other parcels in the 

vicinity of the project site. To ensure the success of planted oak trees, the trees should be monitored by a 

qualified biologist for five years, with a target survival goal of 60 percent every third year. If determined 

after the third year of monitoring period the 60 percent survival rate is not being met, additional trees 

should be planted to meet a 80 percent survival goal by the end of five years. Additionally, trees removed 

for construction shall be assessed by a qualified biologist to see if the removed tree would be suitable for 

replacement elsewhere.

6.5 WETLANDS AND WATERS OF THE U.S 

“Wetlands” are defined in 33 CFR Part 328 as: 

• Waters of the U. S. that are inundated or saturated by surface or groundwater at a frequency 

and duration sufficient to support, and under normal circumstances do support, a prevalence 

of vegetation typically adapted for life in saturated soil conditions. 

Wetlands that meet these criteria during only a portion of the growing season are classified as seasonal 

wetlands. The term “waters of the United States” is defined in 33 CFR Part 328 as: 

• All waters which are currently used, or were used in the past, or may be susceptible to use in 

interstate or foreign commerce, including all waters which are subject to the ebb and flow of 

the tide; 

• All interstate waters including interstate wetlands; or 

• All other waters such as intrastate lakes, rivers, streams (including intermittent streams), 

mudflats, sand flats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or 

natural ponds, the use or degradation of which could affect interstate or foreign commerce 

including any such waters; 

• Which are or could be used by interstate or foreign travelers for recreational or other 

purposes; or 

• From which fish or shellfish are or could be taken and sold in interstate or foreign 

commerce; or 

• Which are used or could be used for industrial purposes by industries in interstate 

commerce. 

Potential to Occur On-site: As discussed in Section 6.3, AES staff conducted a formal wetland 

delineation within the project site (Figure 11). A total of 1.6 acres of potential wetlands and waters of the 

U.S. were mapped within the project site. The wetland delineation report identified a total of 1.297 acres 

of wetland features are likely to be considered jurisdictional features by the USACE pursuant to the CWA 

(AES, 2010a). Another 0.287 acre of wetland features (one stock pond, two seasonal wetlands, one 

seasonal wetland swale, and the two isolated pits) would likely not be considered jurisdictional waters of 

the U.S. The wetland delineation is subject to USACE verification under Section 404 of the CWA. If the 

USACE agrees that the previously mentioned features are not jurisdictional, then 1.297 acres of wetlands 

and waters within the project site would be subject to USACE jurisdiction under the CWA. The wetland 

features are also depicted on the habitat map (Figure 8). 

 

6.5.1 POTENTIAL IMPACTS AND RECOMMENDED MITIGATION

Potential Impacts: The proposed project has been designed to avoid aquatic features to the maximum 

extent feasible. However, the proposed project has the potential to directly impact the wetland features 

within the project site should project development result in fill or discharge within them. It could also 
Biological Assessment 

Analytical Environmental Services 42 Lytton Residential Development

September 2010 Biological Assessment

result in indirect or cumulative impacts to the wetland features if water quality is affected by the proposed 

project. Implementation of the recommended mitigation measures below would reduce impacts to 

wetlands and other waters of the U.S. to less-than-significant levels and compensate for any 

wetland/waters acreages affected by the proposed project. 

Recommended Mitigation Measure(s): The following recommended mitigation measures are presented 

below to avoid and/or reduce impacts to waters of the U.S. (including wetlands) within the project site: 

 A 50-foot setback, where possible, shall be established around each of the potentially 

jurisdictional wetland features within the project development and no development shall occur 

within the setback areas. 

 Prior to the onset of construction activities, these wetland avoidance setbacks shall be 

established around jurisdictional wetland features using high-visibility fencing. A qualified 

biologist shall be present during construction activities that ensue within the vicinity of the 

wetland avoidance buffer zones. The qualified biologist shall monitor during construction to 

make sure that the fencing remains intact and that construction activities do not penetrate the 

wetland avoidance buffer zones. When project development is completed, the high-visibility 

fencing may be removed. 

 Temporary fencing shall be installed around riparian habitats. Fencing shall be in place prior to 

the initiation of any construction activities and no encroachment into the fenced areas shall be 

permitted. Fencing shall remain in place until all construction activities have ceased. 

 Any proposed construction activities that would occur within 50 feet of jurisdictional waters of 

the U.S. shall be conducted during the dry season (i.e., April 15 through October 15) to further 

reduce sedimentation within the watershed. 

 If complete avoidance of waters of the U.S. is not possible and impacts to wetland features 

cannot be avoided, authorization from the USACE is required. A Section 404 CWA permit 

shall be obtained from the USACE and mitigation ratios defined within the permit conditions 

shall be implemented. Typical Nationwide Permits (NWP) mitigation occurs at a ratio of 1:1 

acres created versus impacted and 2:1 acres preserved versus impacted. Individual permit 

conditions may vary. A CWA Section 401 Water Quality Certification permit from the 

USEPA would also be required. 

6.6 STREAM CHARACTERIZATION AND AQUATIC SPECIES

METHODOLOGY AND BACKGROUND

As previously stated, two locations for an onsite WTRF are available if Alternative B (Figure 4) is 

chosen. To fully assess the potential for impacts to aquatic resources from the proposed discharge of 

tertiary treated effluent to inland surface waters, a detailed physical habitat assessment and stream 

characterization was conducted for unnamed stream tributary to the Russian River (proposed WTRF 

location 1) and the unnamed stream tributary to Windsor Creek (WTRF location 2) (Stream 
Biological Assessment 

Analytical Environmental Services 43 Lytton Residential Development

September 2010 Biological Assessment

Characterization: AES, 2010d). Site photos from this field visit are shown in Figures 12, 13 and 14. 

Point locations for these photos are noted in Figure 4. 

Proposed WTRF location 1 is situated in northwestern corner of the project site, while proposed WTRF 

location 2 is situated in the southeastern corner of the project site. Location 1 would discharge tertiary 

treated effluent into an unnamed drainage channel that connects to a roadside ditch along Windsor River 

Road, then follows River Road south prior to flowing west into an abandoned quarry situated adjacent to 

the Russian River (Figure 5). This quarry has no surficial connection to the Russian River, but maintains 

a nexus with the Russian River through subsurface underflow. WTRF location 2 would discharge tertiary 

treated effluent directly into an unnamed tributary to Windsor Creek, which is a tributary to Mark West 

Creek thence the Russian River (Figure 5; AES, 2010d). 

The Windsor Creek and Russian River watershed was evaluated to determine habitat suitability and 

document the potential for occurrence of aquatic dependent special status species associated with these 

stream courses (AES, 2010d). The CDFG Anadromous Fish and Habitat Data Program was utilized to 

determine if any anadromous fish species are documented to occur in the upper reaches of Windsor Creek 

near the unnamed stream associated with the project site (CDFG, 2010). The NMFS database was also 

queried to determine special status species ranges, distributions and designations for Central Valley 

Evolutionary Significant Units (ESUs). Further, a Stream Inventory Report for Windsor Creek (CDFG, 

2006) reporting on the habitat suitability of Windsor Creek for salmonids and other aquatic species was 

reviewed (AES, 2010d). 

SITE HYDROLOGY

The project site is located within the Russian Watershed, Hydrologic Unit Code #18010110 (USGS, 

1978) and is bisected from north to south by the Guerneville and Mark West Hydrologic Sub Areas 

drainage break. The Guerneville sub area drains the western portion of the property (in the vicinity of 

proposed WTRF location 1) while the Mark West sub area drains the eastern (in the vicinity of proposed 

WTRF location 2). Within the Guerneville sub area onsite there is a primary ephemeral drainage which 

initiates flow near the center of the property. This drainage conveys a major portion of the site’s overland 

runoff northwest into the roadside ditch that runs parallel to Windsor River Road. This water crosses 

Eastside Road and continues to flow south along the roadside ditch prior to terminating in the large 

abandoned gravel quarry adjacent the Russian River located west of the project site. The eastern half of 

the property contains one significant ephemeral channel that flows west to east from the hydrologic break, 

initiating flow in the roadside drainage ditch along Windsor River Road. This drainage cuts southeast 

from Windsor River road and then meanders east as it slowly transitions into a seasonal wetland through 

the annual grasslands onsite. This drainage enters a drop inlet which connects to the storm drain system 

from the housing development to the north. This storm drainage system flows directly into the unnamed 

tributary to Windsor Creek. The exit point of this storm drainage system is just west of the stream 

channel, along the eastern property boundary. Two large concrete storm drain culverts empty into the 

unnamed tributary from this location (Figure 13, Photo 4). From this point downstream, the hydrology

of the channel is significantly altered since the influence from point source storm drainage flows during 

heavy runoff events has evidently altered the character of the channel as noted in the channel dimensions 

at the southern property boundary (Figure 13, Photo 6). The details from the stream characterization for 

potential discharges to both locations off the property are summarized below and further detailed in the

quarry situated adjacent to the Russian River (Figure 11). These photographs are included in Figure 12. 

Of the 26 cross sections analyzed for the unnamed drainage channel, the average width observed was 2.4 

meters and the average maximum depth was 15 centimeters. Based on the 78 random substrate 

observations along the length of the unnamed drainage, the dominant substrate noted was coarse gravel. 

Coarse gravels constituted 47 percent (%) of the observations, while 45% of the observations were fine 

gravels. The other 8% of the observations were split evenly between fines (< 0.06mm) and concrete, both

measured to be four percent. 

As this channel predominantly flows through an established roadside drainage influenced by only the 

ephemeral drainage onsite and one other drainage to the north, the flows do not get very high. The two 

drainages meet at the point where the onsite drainage enters the roadside ditch along Windsor River Road. 

Observations of bank stability were noted during the survey. At the point where these drainages 

confluence, the roadside slope was noted to be unstable for approximately 30 meters (Figure 12, Photo 

8). From the point where the flow is culverted under the residential driveway downstream to the Windsor 

River Road crossing, the roadside slope is reinforced with a concrete scour bank as seen in Figure 12, 

Photo 9 and is suitably stable from this point downstream. The channel is dominated by blackberry and 

willows along Windsor River Road and large well spaced valley oaks along Windsor River Road. As it 

reaches the point where it flows west into the abandoned quarry, the drainage becomes choked with 

emergent wetland species and transitions into a seasonal wetland as shown in Figure 12, Photo 12. From 

this point, the drainage channel flows directly into the quarry parallel to the access road. Once in the 

quarry, lake waters will evaporate or exchange through underflow influence with the Russian River. 

UNNAMED TRIBUTARY TO WINDSOR CREEK (LOCATION 2)

The average stream width for the unnamed tributary to Windsor Creek is 2.0 meters. The average depth 

is 14 centimeters, while the average maximum depth was observed to be 18 centimeters. The average 

canopy density observed is 15 out of 17 possible measures. 

Fines (<0.06 mm) was the most dominant substrate observed, composing 73% of the random 

observations; fine gravels (2-16 mm) constituted 17% of the substrate observations; woody debris (<0.03 

m) constituted 5% of the substrate observations; sand (0.06-2mm) comprised 4% of the observations; and

two observations of coarse gravels constituted 1% of the observations made within the unnamed tributary 

to Windsor Creek. The substrates within the unnamed tributary are dominated by fine sediments as 

nearly three quarters of all observations during the survey were fine silty loam. It should be noted that 

this heavy layer of fines was layered with detritus and was nearly 15 centimeters deep above the native 

gravel bed load materials. These observations are indicative of a low gradient stream that has heavy input 

of deciduous material and a minimized hydraulic flushing capacity. No depositional sand bars were 

observed throughout the entire stream reach along the eastern property boundary. This is consistent with 

the soil type and the fact that no channel side scouring was observed within the channel throughout the 

reach. The bank stability was good and erosion potential was low based on vegetative cover. 

As stated previously, cover classes were assessed within the unnamed tributary for each habitat tier within 

a 10 square meter plot centered on each transect. Relative scores (1-5) were generated on both banks at 

each transect for ground cover (<0.5m), lower canopy (0.5-5.0m) and upper canopy (>5.0m) density. The 

results of riparian cover class assessment showed that the unnamed tributary was dominated by trees and 

saplings at the upper canopy tier as observed on the aerial imagery. This cover class, on average, 

composed 10-40 percent of the potential upper canopy space in the 10- meter assessment area for each 

bank. The average densitometry reading observed for the entire reach (averaged from 44 transect 

readings) was 15 out of 17, indicative of a dense upper canopy cover. An average of 10-40 percent cover 

was also observed for all vegetation between 0.5 and 5 meters in height along the left bank, while an 

average closer to 10 percent was observed along the right bank for this vegetative layer. Woody shrubs 

and saplings less than 0.5 meters in height were moderately dense along the left bank, comprising on 

average 10-40 percent of the vegetation layer while the right bank averaged just above 10 percent density. 

Herbs and grasses were choked out by the woody shrubs layer along the left bank, representing on 

average 10-40 percent of the ground level vegetation. The right bank was much more dominant, 

comprising 40-75 percent of the ground cover layer of vegetation as the grazing pasture encroaches upon 

the stream corridor in this area. The riparian canopy is well established and complex in this corridor, but 

the lower tiers of vegetation are predominantly invasive and encroaching, which lowers the vegetative 

habitat values. The lower canopy appeared poorly established in general. Just downstream of transect A, 

the stream becomes highly choked with blackberry, poison oak vines, and oak branches. The dominant 

tree species observed in the upper canopy tier included valley oak, blue oak, black oak, and willows. A 

few sparse Eucalyptus sp. were also observed. 

The results for instream habitat complexity showed that most habitat attributes such as large woody debris 

(>0.3m), undercut banks, and boulders were completely absent from the unnamed tributary; while 

overhanging vegetation, emergent vegetation, filamentous algae, and live tree roots were sparsely (<10%) 

observed in the channel. The gradient for the unnamed tributary is less than one percent. This is too fine 

of a measurement for a handheld field clinometer, therefore slope measurements were not taken during 

the characterization. A topographic scale was used to calculate the gradient from initiation to the 

confluence with Windsor Creek (0.56%).

6.6.1 IMPACTS DISCUSSION (LOCATION 1) 

Potential to Occur On-site: The unnamed drainage channel that extends from the northwest corner of 

the property (proposed WTRF location 1 under Alternative B) to the abandoned quarry is best 

characterized as a roadside ditch. Although this channel initiates flow from two ephemeral drainages and 

supports a dominant gravel substrate base, it does not contain the habitat suitability, surficial connection, 

vegetative cover, or flow duration that would support a significant number of commonly occurring local 

aquatic species. It receives flashy roadside runoff during rain events that may contribute petroleum based 

pollutants due to this influence. No aquatic species were observed during the survey. Based on the 

hydro-period, habitat discontinuity, and due to the lack of instream habitat complexity and riparian cover, 

the unnamed drainage channel to the Russian River does not have the potential to support any aquatic 

special status species (AES, 2010d). 

Potential Impacts: The proposed WTRF at either locations 1 or 2 under Alternative B (location 2 under 

Alternative C) will produce disinfected tertiary treated recycled water consistent with Title 22 

requirements. These standards are set to maintain that all discharged water is maintained free of toxic 

substances in concentrations that are toxic to, or that produce detrimental physiological responses in 

human, plant, animal, or aquatic life. Therefore the proposed discharge will meet or exceed water quality 

standards of the Basin Plan for surface waters, and will not adversely affect the designated beneficial uses 

for aquatic life in the receiving water bodies, Windsor Creek, Mark West Creek or the Russian River. 

(AES, 2010d). 

6.6.2 IMPACTS DISCUSSION (LOCATION 2) 

Potential to Occur On-site: The habitat quality observed in the unnamed tributary to Windsor Creek 

(proposed WTRF location 2 under Alternative B, single location for Alternative C) is minimally suitable 

for a suite of regionally occurring common and sensitive freshwater species typically found within the 

Russian River hydrologic unit. While the unnamed tributary to Windsor Creek is a perennial stream 

course, the seasonal fluctuations in flow and the utilization of the available instream habitat by aquatic 

species is highly variable. The potential for aquatic species to use the unnamed stream to Windsor Creek 

is progressively based on water availability, then ambient temperature, then niche availability. The 

unnamed tributary supported no diversity in flow regime habitat as the gradient was below 1% and the 

reach was saturated by both fine and course particulate organic decomposing matter. This has created a 

very anoxic and narrow niche for macroinvertebrates, leading to low species richness. Very few 

invertebrates other than mosquito larvae were observed during the field survey. These conditions would 

limit the presence of any organisms in need of cool clear flowing water and intolerant to low dissolved 

oxygen levels such as salmonids, foothill yellow legged frogs, or macroinvertebrate species. Species 

richness is an indicator of relative stream health and niche availability, and can be the basis for a 

multitude of biological assumptions and hypotheses. Overall, the unnamed tributary to Windsor Creek 

lacks the variety of high quality habitats to support a diversity of aquatic species. Additionally, there are 

potential water quality impacts to the unnamed tributary from the residential development to the north. 
Biological Assessment 

Analytical Environmental Services 50 Lytton Residential Development

September 2010 Biological Assessment

Stormwater from the residential development is assumed to flow into the unnamed tributary through the 

culverts shown in Figure 13, Photo 4. 

Many of the streams tributary to and associated with the lower Russian River have the potential to support 

few special status fish species. Three special status salmonid species listed under the FESA have the 

potential to use the unnamed stream tributary to Windsor Creek, Windsor Creek and/or Mark West 

Creek: the California Coastal fall-run Chinook salmon (Federally Threatened; FT), the Central California 

Coast coho salmon (Federally Endangered; FE) (Oncorhynchus kisutch) and the Central California Coast 

steelhead trout (FT). Of these three species, only the Central California Coast steelhead trout has been 

documented to occur in Windsor Creek. As shown in Figure 5 the documented natural limit to anadromy 

is just above the Trenton Healdsburg Bridge crossing on Mark West Creek. Therefore, migratory fish 

species have no potential to occur on or within the vicinity of project site. 

Only the most adapted species within this narrow range of suppressed aquatic habitat would be predicted 

to occur within the upper reaches of the unnamed tributary to Windsor Creek. Based on the observations 

made during the stream assessment, this stream reach is unsuitable for Central California Coast steelhead 

spawning and rearing. While the stream reach within the project site does not contain the instream habitat 

complexity to support cold freshwater habitat for spawning, reproduction, or early development, it does 

contain the suitability for all other beneficial use designations for the Mark West HSA. 

Potential Impacts: Because the discharged tertiary treated effluent shall meet Title 22 standards, the 

potential impacts from the WTRF discharge from either locations 1 or 2 would be less than significant. 

Tertiary treated effluent wastewater discharge under Alternative B and C could potentially benefit the 

water quality in this stream (AES, 2010d). In addition, a stream setback corridor, consistent with 

wetlands setbacks for the project, will be established for the unnamed stream tributary to Windsor Creek 

to promote native vegetation establishment and ensure stream bank stabilization at the discharge point. 

This will increase aquatic habitat value and allow the establishment of vegetation which will reduce the 

potential for bank erosion in the discharge channel. 

If Alternative A is implemented, the Tribe will connect to the Town of Windsor’s municipal system. 

Currently the Town of Windsor operates a wastewater treatment facility and discharges advanced treated 

effluent directly into Mark West Creek under NPDES No. CA0023345 (USEPA, 2007). As shown in 

Figure 5, this discharge point is located downstream from the proposed project and the Town of Windsor, 

at the Trenton-Healdsburg Bridge crossing to Mark West Creek just above the confluence to the Russian 

River. Figure 14, Photo 17 shows Mark West Creek at the Trenton-Healdsburg Bridge crossing.

6.8 FEDERALLY LISTED PLANT SPECIES

As discussed in Section 4.2, an analysis was conducted to determine which of the regionally occurring 

federal special-status species has the potential to occur within the project site. It was determined that the 

project site has suitable habitat for six federal special-status plant species but no animal species. Species 

descriptions for these plants are provided below. None of these plant species have been observed onsite 

during focused botanical surveys conducted within parcels (which were acquired in phases) between 2007 

and 2010 (Attachment E). However, potential impacts to these plants and recommended mitigation (if 

found) are described below for each species. One more year of focused botanical surveys shall be 

conducted for certain parcels, as outlined in Attachment E. 

SPECIES DESCRIPTIONS 

SONOMA ALOPECURUS (ALOPECURUS AEQUALIS VAR. SONOMENSIS)

Federal Status: Endangered 

Critical Habitat Designation/Recovery Plan: Critical habitat has not yet been designated for this 

species. Likewise, a recovery plan for this species does not yet exist. However, this species will be 

addressed in a recovery plan for coastal plant species, which is under development. 

Habitat and Biology: Sonoma alopecurus is a tufted perennial grass that occurs in freshwater marshes 

and swamps and riparian scrub habitats. This species occurs at elevations that range from five to 365 

meters (16 to 1,197 feet) above msl. Most of the extant populations of this species occur in freshwater 

marshes. However, Sonoma alopecurus has also been documented along wet banks and within 

streambeds in riparian scrub habitats, within trampled shallow stock-ponds, and within slow-moving 

ephemeral drainages (CNPS, 2009). Sonoma alopecurus blooms from May through July. 

The number of individuals in populations of Sonoma alopecurus fluctuates markedly between years. The 

mechanisms responsible for this variability and obvious decline of this species are poorly understood. 

Sonoma alopecurus appears to experience very low reproductive success and seems particularly 

vulnerable to trampling and grazing from cattle. It competes poorly with invasive plant species, which is 

another contributing factor associated with its decline. 
Biological Assessment 

Analytical Environmental Services 52 Lytton Residential Development

September 2010 Biological Assessment

Sonoma alopecurus is known for having spikelets (excluding the awns) that are less than four millimeters 

(mm) long and straight (as opposed to bent) awns that barely exceed the body of the lemmas by zero to 

two mm. Its longer awns, more robust and upright appearance, generally wider panicle, and violet-gray 

tinged spikelets discern this species from others in the genus; but it is often difficult to distinguish. 

Regional Distribution: The known range of this species includes Marin and Sonoma counties. The 

majority of extant populations of Sonoma alopecurus occur within the Point Reyes National Seashore in 

Marin County. The nearest documented occurrence of this species is located 4.85 miles southwest of the 

project site (CDFG, 2003). This is CNDDB Occurrence Number 21, and it was documented in the 

Forestville Marsh, approximately 0.5 mile east of the Town of Forestville, and northwest of Sebastopol. 

The exact location information is unknown and the record is from a 1972 collection by Sharsmith (CDFG, 

2003). 

 

Potential to Occur On-site: The aquatic features and the mixed riparian within the project site are 

considered suitable habitat for this species. Sonoma alopecurus was not observed on-site during the 

floristic surveys between 2007 and 2010, which were conducted within the appropriate bloom period for 

this species (Attachment E). 

Potential Impacts: Since Sonoma alopecurus was not observed within the project site during any of the 

floristic surveys, the proposed project would not result in direct or indirect impacts to this species through 

loss of suitable habitat. 

Recommended Mitigation Measure(s): Since Sonoma alopecurus was not observed within the project 

site during the floristic surveys, no further mitigation is required. 

PITKIN MARSH LILY (LILIUM PARDALINUM SSP. PITKINENSE) 

Federal Status: Endangered

Critical Habitat Designation/Recovery Plan: Critical habitat has not yet been designated for this 

species. Likewise, a recovery plan for this species does not yet exist. However, this species will be 

addressed in a recovery plan for coastal plant species, which is under development. 

 

Habitat and Biology: Pitkin Marsh lily is a bulbiferous herb that occurs in cismontane woodland, 

meadows and seeps, and freshwater marshes and swamps. It is found on mesic, sandy soils. This species 

occurs at elevations that range from 35 to 65 meters (114 to 214 feet) above msl. This species is known 

from only three occurrences near the town of Sepastopol, in Sonoma County in an area that has been 

referred to historically as the Pitkin Marsh. As such, Pitkin Marsh lily is considered one of the rarest 

plants in the state. All three of these occurrences are within approximately eight miles from one another. 

Two of the three CNDDB documented occurrences of Pitkin Marsh lily are located on the periphery of

freshwater marsh habitats and the third is located in a mesic area near a creek (CDFG, 2003). Pitkin 

Marsh lily blooms from June through July. 

Pitkin Marsh lily is thought to be in decline due to loss of habitat from urbanization and habitat 

fragmentation. In addition competition from invasive plant species and trampling and herbivory by 

livestock and wildlife species continue to threaten this species. 

This species is known for having a pendant, nodding inflorescence, whorled leaves, and for occurring in 

moist habitats. It has two-toned perianth segments that are typically yellow toward the center and darker 

red at the tips. The anthers tend to be between six and 11 mm long and magenta colored and the pollen is 

red or brownish-orange. The bulb scales of this species typically have two segments. 

Regional Distribution: The known range of this species is restricted to Sonoma County. The nearest 

documented occurrence of this species is located approximately 3.02 miles south of the project site 

(CDFG, 2003). This is CNDDB Occurrence Number 1, and it was documented in the historic Pitkin 

Marsh area. The exact location information is suppressed and the population was last seen in 1996 

(CDFG, 2003). 

 

Potential to Occur On-site: The aquatic features within cismontane woodland and the mixed riparian 

within the project site are considered suitable habitat for this species. The perennial drainage on-site 

provides a hydrological connection to areas historically referred to as the Pitkin Marsh. Pitkin Marsh lily 

was not observed on-site during the floristic surveys between 2007 and 2010, which were conducted 

within the appropriate bloom period for this species (Attachment E). 

Potential Impacts: Since the Pitkin Marsh lily was not observed within the project site during any of the 

floristic surveys, the proposed project would not result in direct or indirect impacts to this species through 

loss of suitable habitat. 

Recommended Mitigation Measure(s): Since the Pitkin Marsh lily was not observed within the project 

site during the floristic surveys, no further mitigation is required. 

SONOMA SUNSHINE (BLENNOSPERMA BAKERI)

Federal Status: Endangered 

Critical Habitat Designation/Recovery Plan: Critical habitat has not yet been designated for this 

species. Likewise, a recovery plan for this species does not yet exist. 

Habitat and Biology: Sonoma sunshine is annual herb that occurs in a mesic habitats within Valley and 

foothill grasslands and vernal pool habitats. This species is known to occur at elevations that range from 

approximately ten to 110 meters (32 to 360 feet) above msl. As with Burke’s goldfields, Sonoma

sunshine is known to occur on soils within the Huichica loam series in the northern portions of the Santa 

Rosa Plain and on soils within the Wright loam and Clear Lake clay series the southern portions of the 

Santa Rosa Plain (USFWS, 2007). This species blooms from March through May and has been known to 

occasionally begin flowering as early as mid-February. This species is known to co-occur with Burke’s 

goldfields and Sebastopol meadowfoam. 

Like other annual species that occur in uncertain or variable habitats, Sonoma sunshine appears to have a 

substantial and persistent seed bank that is able to persist until conditions a favorable for germination. As 

such, population extent, numbers of individuals, and whether or not this species blooms at all in a given 

location varies dramatically from year to year given the amount of rainfall and other varying 

environmental factors. Extirpation and/or absence of this species within suitable habitats should not be 

assumed during adverse conditions (i.e., drought, disturbance, etc.) because of its persistent seed bank. 

Sonoma sunshine is distinguished from other members of the genus because the stigmas of the ray 

flowers are dark red. All the other species in the genus have ray flowers with yellow stigmas. Sonoma 

sunshine tends to be more robust in general and its lower leaves are typically entire. The upper leaves 

have between one and three lobes, while other members of the genus have between three and 15 lobes 

leaves. 

Regional Distribution: Sonoma sunshine is endemic to Sonoma County and this is the only known 

region where this species occurs. Most of the extant populations of this species occur on the Santa Rosa 

Plain. The nearest documented occurrence of Sonoma sunshine is located 4.91 miles southwest of the 

project site. This is CNDDB Occurrence Number 6, and three colonies of this species were observed at 

the Wood Road Elbow, approximately 0.7 mile west of Fulton Road, northwest of Santa Rosa. All three 

colonies were documented within vernal pools and swales on private property and it appears that this 

population was last seen in 1994 (CDFG, 2003). 

Potential to Occur On-site: The aquatic features and any mesic areas within the annual grassland 

habitat on-site are considered suitable habitat for this species. Sonoma sunshine has not been observed 

on-site during the floristic surveys between 2007 and 2010, which were conducted within the appropriate 

bloom period for this species. Prior to conducting the floristic surveys, a reference population of Sonoma 

sunshine was observed at the Todd Road location (Attachment E). 

 

Potential Impacts: The proposed project has the potential to result in direct impacts to Sonoma sunshine 

should it occur within the project site. The proposed project could also result in indirect impacts to this 

species through loss of suitable habitat. Habitat loss is considered a significant impact to the federally 

listed plant species on the Santa Rosa Plain because a persistent seed bank may be present even if the 

actual plant species were not observed. Favorable conditions could result in germination of the seed bank 

in the future. It is also considered a significant impact because the listed species may become established

within potentially-impacted suitable habitats naturally or through future human-assisted mitigation 

efforts. 

Recommended Mitigation Measure(s): The remaining floristic surveys shall be conducted within the 

required areas of the project site in accordance with the Conservation Strategy. This includes an 

additional year of surveys on APNs 066-191-016, 066-191-019, 066-191-021, 066-300-023, and 066-

300-017, as well as 066-050-040 and 066-050-047. If the protocol-level floristic survey results are 

negative, no additional mitigation is required. 

If the protocol-level floristic survey results for any parcel are positive, formal consultation with USFWS 

must be initiated immediately. Upon consultation, an appropriate course of action will be established. It 

is likely that the proposed project shall be amended and reconfigured, such that complete avoidance of 

any and all individual plants or populations of these plants is accomplished entirely. Prior to the onset of 

construction activities, on any parcel where the species is identified, the avoidance plan must be 

formulated, submitted, and approved by the USFWS. The USFWS approved special-status plant 

avoidance plan shall be implemented accordingly. 

If avoidance of the special-status plant habitat is not feasible, the Tribe must mitigate for impacts to the 

this habitat according to the mitigation ratios outlined in the Programmatic Consultation for USACE 404 

Permitted Projects that May Affect Four Endangered Plant Species on the Santa Rosa Plain, California

(File Number 223420N) (USFWS, 2007). The mitigation requirements are summarized in Table 8.

BURKE’S GOLDFIELDS (LASTHENIA BURKEI)

Federal Status: Endangered 
Biological Assessment 

Analytical Environmental Services 56 Lytton Residential Development

September 2010 Biological Assessment

Critical Habitat Designation/ Recovery Plan: Critical habitat has not yet been designated for this 

species. Likewise, a recovery plan for this species does not yet exist. 

Habitat and Biology: Burke’s goldfields are annual herbs that occur in a variety of mesic and seasonally 

inundated habitats including wet meadows, seeps, seasonal wetlands, swales, and vernal pools. This 

species is known to occur at elevations that range from approximately 15 to 600 meters (49 to 1,968 feet) 

above msl. In the northern portions of the Santa Rosa Plain (i.e., north of Highway 12), this species is 

known to occur on soils within the Huichica loam series. Huichica loam soils are generally stratified and 

have fine textured clay loam upper regions over strongly cemented duripan layers deep below the surface. 

In the southern portions of the Santa Rosa Plain (i.e., south of Highway 12), Burke’s goldfields are likely 

to occur on soils within the Wright loam and Clear Lake clay series. Wright loams are generally 

composed of a moderate fine and silty upper layers over dense clays and marine sediments that occur 

deep below the surface. Clear Lake clays are generally fine and dense throughout from the surface to 

many feet deep (USFWS, 2007). Burke’s goldfields bloom from April through May. This species is 

known to co-occur with Sonoma sunshine and Sebastopol meadowfoam. 

As an annual herb, Burke’s goldfields are adapted to life in variable and hydrologically fluctuating 

conditions. This species is known to have a persistent seed bank that can survive dormancy for an 

indeterminate number of years, until favorable conditions permit germination. For this reason, 

populations must be monitored for multiple years in order to accurately access their extent and total 

numbers of individuals. As with the other federally listed species on the Santa Rosa Plain, absence or 

extirpation should not be assumed at sites with suitable habitat during adverse conditions because of this 

species persistent seed bank. This species can be easily distinguished from other members of the genus 

by its fruits because they have an unusual pappus of a single long awn and several short scales. 

Regional Distribution: The known range of Burke’s goldfields includes Lake, Mendocino, Napa, and 

Sonoma counties. However, this species is most likely extirpated from Mendocino County. The majority 

of the extant populations of this species occur on the Santa Rosa Plain. The nearest documented 

occurrence of this species within the CNDDB is located approximately 0.09 mile east of the project site. 

This is CNDDB Occurrence Number 22, and it was documented within a large swale in a horse pasture, 

southwest of the Windsor River Road/Starr Road intersection, near the Windsor Grange. This occurrence 

is located on private land (CDFG, 2003). 

 

Potential to Occur On-site: The aquatic features within the project site are considered suitable habitat 

for this species. Burke’s goldfields have not been observed on-site during the floristic surveys between 

2007 and 2010, which were conducted within the appropriate bloom period for this species. Prior to 

conducting the floristic surveys, a reference population of Burke’s goldfields was observed at the Alton 

Road Vernal Pool Preserve (Attachment E). 
Biological Assessment 

Analytical Environmental Services 57 Lytton Residential Development

September 2010 Biological Assessment

Potential Impacts: The proposed project has the potential to result in direct impacts to Burke’s 

goldfields should they occur within the project site. The proposed project could also result in indirect 

impacts to this species through loss of suitable habitat. Habitat loss is considered a significant impact to 

the federally listed plant species on the Santa Rosa Plain because a persistent seed bank may be present 

even if the actual plant species were not observed. Favorable conditions could result in germination of 

the seed bank in the future. It is also considered a significant impact because the listed species may 

become established within potentially-impacted suitable habitats naturally or through future humanassisted mitigation efforts. 

Recommended Mitigation Measure(s): The mitigation measures to avoid potential impacts to Burke’s 

goldfields are the same as those recommended for Sonoma sunshine. 

SEBASTOPOL MEADOWFOAM (LIMNANTHES VINCULANS)

Federal Status: Endangered 

Critical Habitat Designation/ Recovery Plan: Critical habitat has not yet been designated for this 

species. Likewise, a recovery plan for this species does not yet exist. 

Habitat and Biology: Sebastopol meadowfoam is an annual herb that occurs in meadows and seeps, 

mesic areas within Valley and foothill grasslands, and vernal pools. It also occurs in seasonal wet swales, 

wet meadows, along streambanks, and in man-made aquatic features such as drainage ditches. This 

species occurs at elevations that range from approximately 15 to 305 meters (49 to 1,000 feet) above msl. 

Sebastopol meadowfoam frequently occurs on Wright loam or Clear Lake clay soil types. It has 

occasionally been found on other soil types including Pajaro clay loam, Cotati fine sandy loam, Hair clay 

loam, and Blucher fine sandy loam (USFWS, 2007). This species blooms from April through May. This 

species is known to co-occur with Sonoma sunshine and Burke’s goldfields. 

Sebastopol meadowfoam typically germinates after the first significant rains. The seedlings grow slowly, 

submerged in the aquatic environment over the winter, and growth rates decrease as the water dries out. 

Repeated drying and filling of aquatic features throughout the season favors robust growth. As with the 

other annual herbs of the Santa Rosa Plain, this species has a persistent and long-lived seed bank. For this 

reason, extirpation or absence of this species within suitable habitats should not be assumed during years 

of adverse conditions. 

This species is distinguished from other members of the genus by its stamens, petals, and leaflets. The 

stamens of Sebastopol meadowfoam are approximately five to eight mm long and the petals are 

approximately ten to 18 mm long. The petals of this specie typically reflex (i.e., fall out as opposed to in) 

as the fruits mature. Sebastopol meadowfoam tends to have between three to five leaflets that are entire, 

as opposed to toothed or lobed leaves. 

 
Biological Assessment 

Analytical Environmental Services 58 Lytton Residential Development

September 2010 Biological Assessment

Regional Distribution: The known range of this species includes Napa and Sonoma counties. Most of 

the known occurrences of Sebastopol meadowfoam are located on the Santa Rosa Plain. The nearest 

documented occurrence of this species is located 2.15 miles southeast of the project site. This is CNDDB 

Occurrence Number 46, which was documented within a swale, in the Sonoma County Airport 

Wildflower Preserve, northwest of the Airport by Pavlik. This population was last monitored in 1993 

(CDFG, 2003). 

Potential to Occur On-site: The aquatic features and any mesic areas within the annual grassland 

habitat on-site are considered suitable habitat for this species. Sebastopol meadowfoam has not been 

observed on-site during the floristic surveys between 2007 and 2010, which were conducted within the 

appropriate bloom period for this species. Prior to conducting the floristic surveys, reference populations 

of Sebastopol meadowfoam were observed at the Alton Road Vernal Pool Preserve and at the Todd Road 

location (Attachment E). 

Potential Impacts: The proposed project has the potential to result in direct impacts to Sebastopol 

meadowfoam should it occur within the project site. The proposed project could also result in indirect 

impacts to this species through loss of suitable habitat. Habitat loss is considered a significant impact to 

the federally listed plant species on the Santa Rosa Plain because a persistent seed bank may be present 

even if the actual plant species were not observed. Favorable conditions could result in germination of 

the seed bank in the future. It is also considered a significant impact because the listed species may 

become established within potentially-impacted suitable habitats naturally or through future humanassisted mitigation efforts. 

Recommended Mitigation Measure(s): The mitigation measures to avoid potential impacts to 

Sebastopol meadowfoam are the same as those recommended for Sonoma sunshine. 

MANY-FLOWERED NAVARRETIA (NAVARRETIA LEUCOCEPHALA SSP. PLIEANTHA) 

Federal Status: Endangered 

Critical Habitat Designation/ Recovery Plan: Critical habitat has not yet been designated for this 

species. However, many-flowered navarretia is addressed in the Recovery Plan for Vernal Pool 

Ecosystems of California and Oregon (USFWS, 2005b). 

Habitat and Biology: Many-flowered navarretia is a low-growing annual herb that typically occurs in 

vernal pool habitats. This species is also known to occur in dry meadows, along the margins of aquatic 

features on volcanic ash substrates, and in openings on wet ground in forested habitats. Many-flowered 

navarretia occurs at elevations that range from approximately 30 to 650 (98 to 2,132) meters above msl. 

This species is known to hybridize with N. leucocephala ssp. pauciflora (as does N. leucocephala ssp. 

bakeri). Many-flowered navarretia blooms from May through June. 
Biological Assessment 

Analytical Environmental Services 59 Lytton Residential Development

September 2010 Biological Assessment

Taxonomy within this group is difficult and as mentioned above and intermediate species have been 

frequently observed. In general, this species can be distinguished from other members of the genus in the 

region by its stature, degree of hairiness, and the size, number, or lobing of its floral parts. Manyflowered navarretia has low, spreading branches and bright blue flowers, while most of the other species 

have white or pale blue flowers. It has more numerous heads and many more flowers per head than the 

other subspecies. In addition, many-flowered navarretia has corollas that are greater than or equal to the 

calyxes and calyx lobes that are generally entire. 

Regional Distribution: The known range of many-flowered navarretia includes Lake and Sonoma 

counties, with most of the occurrences in Lake County. The nearest documented occurrence of this 

species is located 2.04 miles southeast of the project site. This is CNDDB Occurrence Number 9, which 

was documented in vernal pools and swales, approximately two miles south of Windsor and south of 

Saunders Road. The population was first observed in 1986 by Guggolz and was last seen in 1989 by 

Waaland (CDFG, 2003). 

Potential to Occur On-site: The aquatic features and any mesic areas within the annual grassland and 

oak woodland habitats on-site are considered suitable habitat for this species. Many-flowered navarretia 

has not been observed on-site during the floristic surveys between 2007 and 2010, which were conducted 

within the appropriate bloom period for this species (Attachment E). 

Potential Impacts: The proposed project has the potential to result in direct impacts to many-flowered 

navarretia should it occur within the project site. The proposed project could also result in indirect 

impacts to this species through loss of suitable habitat. Habitat loss is considered a significant impact to 

the federally listed plant species on the Santa Rosa Plain because a persistent seed bank may be present 

even if the actual plant species were not observed. Favorable conditions could result in germination of 

the seed bank in the future. It is also considered a significant impact because the listed species may 

become established within potentially-impacted suitable habitats naturally or through future humanassisted mitigation efforts. 

Recommended Mitigation Measure(s): The mitigation measures to avoid potential impacts to manyflowered navarretia are the same as those recommended for Sonoma sunshine. 

6.9 MIGRATORY BIRDS

As discussed in Section 3.0, migratory bird species are protected under the statutes of the MBTA (16 

USC Sections 703-712). 

Potential to Occur On-site: Several migratory bird species have potential to nest, loaf, forage, or perch 

within the habitat types identified in the project site. Several migratory bird species were observed within 

the project site during field surveys. These include: red-tailed hawk (Buteo jamaicensis), red-shouldered 

hawk, Cooper’s hawk (Accipiter cooperi), bushtit (Psaltriparus minimus), Anna’s hummingbird (Calypte

anna), orange-crowned warbler (Vermivora celata), ash-throated flycatcher (Myiarchus cinerascens), 

Nuttall’s woodpecker (Picoides nuttaillii), and great horned owl (Bubo virginianus). A complete list of 

all the bird species observed within the project site is included as Attachment C. Several nests were 

observed within the project site during the surveys. 

6.9.1 POTENTIAL IMPACTS AND RECOMMENDED MITIGATION

Potential Impacts: The proposed project has potential to impact nesting migratory birds directly and 

indirectly if construction activities occur during the avian nesting season. Activities such as building, 

grading, ground disturbance, and vegetation removal could directly impact nesting birds if their nests are 

located within development areas. Increased human activity and traffic, elevated noise levels, and 

operation of machinery could indirectly impact nesting birds if their nests are located within the vicinity 

of development areas. Disturbance of this nature that occurs within 500 feet of an active nest could cause 

nest abandonment or premature fledging of the young. Implementation of the recommended mitigation 

measures presented below would ensure any potential impacts to migratory birds are less-than-significant. 

Recommended Mitigation Measure(s): If any construction activities (e.g., building, grading, ground 

disturbance, removal of vegetation) are scheduled to occur during the avian nesting season 

(approximately February 15 – August 31), pre-construction bird surveys shall be conducted. Preconstruction surveys for any nesting bird species shall be conducted by a qualified wildlife biologist 

throughout all areas of suitable trees and habitat that are within 500 feet of any proposed construction 

activity, including oak trees slated for removal. The surveys shall occur no more than 14 days prior to the 

scheduled onset of construction activities. If construction is delayed or halted for more than 14 days, 

another pre-construction survey for nesting bird species shall be conducted. If no nesting birds are 

detected during the pre-construction surveys no additional surveys or mitigation measures are required. 

If nesting bird species are observed within 500 feet of construction areas during the surveys, appropriate 

avoidance setbacks shall be established. The size and scale of nesting bird avoidance setbacks shall be 

determined by a qualified wildlife biologist and shall be dependent upon the species observed and the 

location of the nest. Avoidance setbacks shall be established around all active nest locations via stakes 

and high visibility fencing. The nesting bird setbacks shall be completely avoided during the duration of 

construction activities and the fencing must remain intact. The qualified wildlife biologist shall also 

determine an appropriate monitoring plan and will decide if construction monitoring is necessary during 

the duration of construction activities. Again, monitoring requirements are dependent upon the species 

observed, the location of the nests, and the number of nests observed. The setback fencing may be 

removed when the qualified wildlife biologist confirms that the nest(s) is no longer occupied and all birds 

have fledged. 

If impacts (i.e., take) to migratory nesting bird species are unavoidable, consultation with USFWS shall 

be initiated. Through consultation, an appropriate and acceptable course of action shall be established.

7.0 INTERRELATED AND INTERDEPENDENT ACTIVITIES 

As previously mentioned, interrelated and interdependent activities are those activities that occur as a 

result of the proposed project. These activities would not occur and would not be required without the 

proposed project and they do not have any independent utility on their own. However, interrelated and 

interdependent activities may result in impacts to biological resources and the effects of these activities 

can be direct or indirect. The interrelated and interdependent activities associated with the proposed 

project include minor road improvements (e.g., the installation of stop signs at the three project access 

driveways on Windsor River Road). Without the proposed project, these road improvements would not 

be necessary and would not occur. 

Construction of the minor road improvements is not expected to result in any impacts to the special-status 

species discussed in this BA since these construction activities will occur within existing roads in 

ruderal/disturbed habitat. Due to the fact that no impacts to special-status species are expected to occur as 

a result of the proposed minor road improvements, it is likely that no interrelated and interdependent 

impacts to potential special-status species or their habitats would occur. 

Alternative A is the preferred alternative and would not require a surface water discharge at either of the 

aforementioned points. Instead, wastewater would be transferred to and treated by the Town of Windsor 

Wastewater Treatment Reclamation and Disposal Facility. Alternative A also includes a connection to 

the Town of Windsor’s public water supply system. It is anticipated that the offsite water and wastewater 

infrastructure and associated pipeline required for connection to the Town of Windsor water supply and 

sewer system would occur primarily along existing disturbed roadways without impacts to sensitive 

habitats. It is also anticipated that interrelated and interdependent impacts to any potentially occurring 

special-status species or their habitats would not occur as a result of this action. This assumption is based 

on the avoidance of all jurisdictional wetland features. If any jurisdictional features were to be impacted, 

then this separate Federal action under a Section 404 permit of the CWA would trigger Section 7 

Consultation under the FESA. Additionally, any state requirements for non-trust land would be adhered 

to, such as a 401 Water Quality Certification. No other potential interrelated and interdependent activities 

are anticipated from the project. 

8.0 CUMULATIVE EFFECTS 

For the purposes of this BA, cumulative effects are defined as the effects of future state, local, or private 

activities that are reasonably certain to occur in the action area. This BA only addresses future state, 

local, or private activities occurring outside the action area if they would result in effects within the action 

area. Future federal actions that are unrelated to the proposed project are not considered in this BA 

because they will be subject to separate and independent consultation pursuant to Section 7 of FESA. 

At this time, no other state, local, or private projects are anticipated to occur in the action area or result in 

cumulative effects within the action area in the foreseeable future. Generally speaking, future 
Biological Assessment 

Analytical Environmental Services 62 Lytton Residential Development

September 2010 Biological Assessment

development projects could result in cumulative impacts to habitats, waters of the U.S., and special-status 

species or their habitats via disturbance and increased human population and activity. Cumulative 

impacts of this nature might include new development projects, habitat fragmentation, net loss of open 

space, edge effects, and disruption of wildlife corridors. However, no specific projects are proposed for 

the action area at this time or in the reasonably foreseeable future. Any proposed future development in 

the action area would be required to mitigate for impacts to biological resources based on CEQA, NEPA, 

CWA, and FESA requirements. Likewise, the proposed project is not anticipated to significantly 

contribute to any cumulative impacts within the action area due to the associated mitigation measures. 

Therefore, no cumulative impacts are anticipated to occur. 

9.0 CONCLUSIONS AND DETERMINATION 

EFFLUENT DISPOSAL AND DISCHARGE 

On-site disposal of treated effluent will involve seasonally storing and reclaiming treated effluent with 

excess to be discharged to unnamed drainage channels, as discussed for locations 1 and 2 for the first 

option under Alternative B described in Section 1.2. The second option under Alternative B involves 

complete on-site reclamation and disposal of treated effluent utilizing storage detention basins and 

irrigation areas (including landscaping and parks). AES biologists conducted a stream characterization of 

both the unnamed drainage channel described for WTRF location 1 and the unnamed tributary to Windsor 

Creek described for location 2 (AES, 2010d), the results of which are summarized in Section 6.6. The 

unnamed drainage channel and the unnamed tributary to Windsor Creek do not contain suitable habitat 

for any special status fish species and do not support a high biodiversity of macroinvertebrates or other 

aquatic species. Thus the proposed project would not affect any threatened or endangered fish species 

because neither of the proposed tertiary treated effluent disposal locations provide suitable habitat for 

fish. In the event either Alternatives B or C are implemented, an NPDES permit would be required from 

the USEPA. 

SPECIAL-STATUS SPECIES

The aquatic features, mixed riparian, mixed oak woodland, and/or oak savannah habitats within the 

project site may provide suitable habitat for the following federally listed special-status plant species: 

Sonoma alopecurus, Sonoma sunshine, Burke’s goldfields, Sebastopol meadowfoam, Pitkin Marsh lily, 

and many-flowered navarretia. The proposed project is not likely to adversely affect these potentially 

occurring special-status plant species because none of these species are expected to occur within the 

project site. Several protocol-level floristic surveys have been conducted between 2007 and 2010 for the 

potentially occurring special-status plants within the project site and have had substantiated negative 

results (Attachment E). Additional protocol-level floristic surveys will be conducted within the 

remaining parcels of the project site and substantiated negative results are expected (Attachment E). 

Implementation of the recommended mitigation measures will ensure that any potential impacts to 

special-status plants or their habitats resulting from the proposed project will be less-than-significant or 

completely avoided. 
Biological Assessment 

Analytical Environmental Services 63 Lytton Residential Development

September 2010 Biological Assessment

The proposed project would not affect California tiger salamander because the project falls outside its 

known range (USFWS, 2005a). Furthermore, no suitable habitat occurs within the project site for 

California tiger salamander. 

MIGRATORY BIRDS

Habitat types within the project site provide suitable nesting and foraging habitat for numerous migratory 

bird species. The proposed project would not affect migratory nesting bird species because 

implementation of the recommended mitigation measures will ensure that any potential impacts will be 

less-than-significant or completely avoided.

Important Information About Your Species List 

How We Make Species Lists 

We store information about endangered and threatened species lists by U.S. Geological 

Survey 71⁄2 minute quads. The United States is divided into these quads, which are about the

size of San Francisco. 

The animals on your species list are ones that occur within, or may be affected by projects 

within, the quads covered by the list. 

Fish and other aquatic species appear on your list if they are in the same watershed as your 

quad or if water use in your quad might affect them. 

Amphibians will be on the list for a quad or county if pesticides applied in that area may be 

carried to their habitat by air currents.

Birds are shown regardless of whether they are resident or migratory. Relevant birds on the 

county list should be considered regardless of whether they appear on a quad list. 

Sacramento Fish & Wildlife Office Species List Page 6 of 8

http://www.fws.gov/sacramento/es/spp_lists/auto_list.cfm 12/24/2009
Plants

Any plants on your list are ones that have actually been observed in the area covered by the 

list. Plants may exist in an area without ever having been detected there. You can find out 

what's in the surrounding quads through the California Native Plant Society's online

Inventory of Rare and Endangered Plants.

Surveying

Some of the species on your list may not be affected by your project. A trained biologist 

and/or botanist, familiar with the habitat requirements of the species on your list, should 

determine whether they or habitats suitable for them may be affected by your project. We 

recommend that your surveys include any proposed and candidate species on your list. 

See our Protocol and Recovery Permits pages.

For plant surveys, we recommend using the Guidelines for Conducting and Reporting 

Botanical Inventories. The results of your surveys should be published in any environmental 

documents prepared for your project. 

Your Responsibilities Under the Endangered Species Act 

All animals identified as listed above are fully protected under the Endangered Species Act of 

1973, as amended. Section 9 of the Act and its implementing regulations prohibit the take of

a federally listed wildlife species. Take is defined by the Act as "to harass, harm, pursue, 

hunt, shoot, wound, kill, trap, capture, or collect" any such animal. 

Take may include significant habitat modification or degradation where it actually kills or 

injures wildlife by significantly impairing essential behavioral patterns, including breeding, 

feeding, or shelter (50 CFR §17.3). 

Take incidental to an otherwise lawful activity may be authorized by one of two 

procedures:

If a Federal agency is involved with the permitting, funding, or carrying out of a project that may 

result in take, then that agency must engage in a formal consultation with the Service.

During formal consultation, the Federal agency, the applicant and the Service work together to 

avoid or minimize the impact on listed species and their habitat. Such consultation would result 

in a biological opinion by the Service addressing the anticipated effect of the project on listed and

proposed species. The opinion may authorize a limited level of incidental take. 

If no Federal agency is involved with the project, and federally listed species may be taken as 

part of the project, then you, the applicant, should apply for an incidental take permit. The 

Service may issue such a permit if you submit a satisfactory conservation plan for the species 

that would be affected by your project. 

Should your survey determine that federally listed or proposed species occur in the area and are 

likely to be affected by the project, we recommend that you work with this office and the 

California Department of Fish and Game to develop a plan that minimizes the project's direct and 

indirect impacts to listed species and compensates for project-related loss of habitat. You should 

include the plan in any environmental documents you file. 

Critical Habitat 

When a species is listed as endangered or threatened, areas of habitat considered essential 

to its conservation may be designated as critical habitat. These areas may require special 

management considerations or protection. They provide needed space for growth and 

normal behavior; food, water, air, light, other nutritional or physiological requirements;

cover or shelter; and sites for breeding, reproduction, rearing of offspring, germination or 

seed dispersal. 

Sacramento Fish & Wildlife Office Species List Page 7 of 8

http://www.fws.gov/sacramento/es/spp_lists/auto_list.cfm 12/24/2009
Although critical habitat may be designated on private or State lands, activities on these 

lands are not restricted unless there is Federal involvement in the activities or direct harm to 

listed wildlife. 

If any species has proposed or designated critical habitat within a quad, there will be a 

separate line for this on the species list. Boundary descriptions of the critical habitat may be 

found in the Federal Register. The information is also reprinted in the Code of Federal 

Regulations (50 CFR 17.95). See our Map Room page. 

Candidate Species 

We recommend that you address impacts to candidate species. We put plants and animals 

on our candidate list when we have enough scientific information to eventually propose them

for listing as threatened or endangered. By considering these species early in your planning 

process you may be able to avoid the problems that could develop if one of these candidates 

was listed before the end of your project. 

Species of Concern 

The Sacramento Fish & Wildlife Office no longer maintains a list of species of concern. 

However, various other agencies and organizations maintain lists of at-risk species. These 

lists provide essential information for land management planning and conservation efforts. 

More info

Wetlands

If your project will impact wetlands, riparian habitat, or other jurisdictional waters as defined

by section 404 of the Clean Water Act and/or section 10 of the Rivers and Harbors Act, you 

will need to obtain a permit from the U.S. Army Corps of Engineers. Impacts to wetland 

habitats require site specific mitigation and monitoring. For questions regarding wetlands, 

please contact Mark Littlefield of this office at (916) 414-6580. 

Updates

Our database is constantly updated as species are proposed, listed and delisted. If you 

address proposed and candidate species in your planning, this should not be a problem. 

However, we recommend that you get an updated list every 90 days. That would be March 

24, 2010.

ON-SITE

Northern Hardpan Vernal Pool CNDDB tracked "Red Dirt Hogwallow Lands" primarily on 

old alluvial terraces on the east side of the 

Great Valley from Tulare or Fresno 

County north to Shasta County. 

A low, amphibious, herbaceous community 

dominated by annual herbs and grasses. 

Germination and growth begin with winter rains, 

often continuing even when inundated. Rising 

spring temperatures evaporate the pools, leaving 

concentric bands of vegetation that colorfully 

encircle the drying pool. Old, very acidic, Fe-Si 

cemented hardpan soils (Redding, San Joaquin, 

and similar series). The microrelief on these 

soils typically is hummocky, with mounds 

intervening between localized depressions. 

Winter rainfall perches on the hardpan, forming 

pools in the depressions. Evaporation (not 

runoff) empties the pools in spring . 

N/A No. This habitat type does not exist 

within the project site. This habitat 

type is tracked by the CNDDB for 

the quadrangles queried.

October 2010 Technical Memorandum: Botanical Surveys 

1.0 INTRODUCTION 

This Technical Memorandum (Memorandum) has been prepared for the Lytton Rancheria of California 

(Tribe), to report the results of a series of botanical surveys conducted by Analytical Environmental 

Services (AES) throughout the approximately 124.12-acre Lytton Residential Development property 

(project site). This Memorandum describes the methodology, results, and general status of the botanical 

survey efforts that have been conducted within the project site to date. 

1.1 PROJECT LOCATION

The project site is located west of Interstate Highway 101, east of the Russian River, and is approximately 

one mile west of the Town of Windsor, within Sonoma County, California (Figure 1). The project site 

occurs within Sections 14, 15, and unsectioned areas of Molinos, Township 8 North, and Range 9 West, 

Mount Diablo Baseline and Meridian (MDBM) in the “Healdsburg, CA” U.S. Geological Survey (USGS) 

7.5-minute topographic quadrangle (USGS, 1993) (Figure 2). It is located within the Russian Watershed 

Hydrologic Unit Code #18010110 (USGS, 1978). The project site is composed of fourteen assessor’s 

parcel numbers (APNs) that were included in the original Biological Assessment (APNs 066-300-028, 

066-300-031, 066-300-033, 066-191-017, 066-191-018, 066-191-020, and 066-191-022; AES, 2009), as 

well as additional parcels acquired after the original parcels were obtained (066-191-016, 066-191-019, 

066-191-021, 066-191-023, 066-300-017, 066-050-040, 066-050-047; Figure 3). These APNs, listed in 

order from west to east, are discussed in further detail in Table 1. 

1.2 PROJECT DESCRIPTION 

The proposed project (i.e., action) includes the placement of approximately 124.12 acres of land into 

federal trust for the Tribe and construction of residential housing, Tribal government offices, a Tribal 

community center, retreat, roundhouse, and associated facilities. More extensive information regarding 

Alternatives A, B, C and D is provided in the Final Environmental Assessment (EA) for the Lytton 

Residential Development (AES, 2011). In addition to the taking of 124.12 acres of land into federal trust 

on behalf of the Tribe, the proposed project has several other derivative components which include road 

improvements, grading, utilities, water supply infrastructure, two possible locations for a wastewater 

treatment and reclamation facility (under Alternative B), and storm water drainage components. 

1.3 PURPOSE AND NEED 

As mentioned above, AES has conducted a series of botanical surveys within the project site. The Bureau 

of Indian Affairs (BIA) is the lead agency for the proposed project under the National Environmental 

Policy Act (NEPA) and as such, has the primary authority for approval of the proposed project. The 

purpose of this report is to document the results and status of the botanical survey efforts that have been 

conducted within the project site in support of any NEPA and/or California Environmental Quality Act

2.0 REGULATORY SETTING 

The following section summarizes the applicable Federal regulations that relate to the botanical resources 

that may occur within the project site. Other pertinent State and local regulations are also discussed 

below for the purpose of providing generalized information regarding regulations that would be 

applicable if the project site is not placed into federal trust for the Tribe. 
Technical Memorandum 

Analytical Environmental Services 6 Lytton Residential Development Project 

October 2010 Technical Memorandum: Botanical Surveys 

2.1 FEDERAL

FEDERAL ENDANGERED SPECIES ACT

The United States Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service 

(NMFS) implement the Federal Endangered Species Act (FESA) of 1973 (16 USC Section 1531 et seq.). 

Threatened and endangered species on the federal list (50 CFR Subsection 17.11, 17.12) are protected 

from “take” (direct or indirect harm), unless a Section 10 Permit is granted to an individual or a Section 7 

consultation and a Biological Opinion with incidental take provisions are rendered to a lead federal 

agency. Pursuant to the requirements of FESA, an agency reviewing a proposed project within its 

jurisdiction must determine whether any federally listed species may be present in the project area and 

determine whether the proposed project will have a potentially significant impact upon such species. 

Under FESA, habitat loss is considered to be an impact to the species. In addition, the agency is required 

to determine whether the project is likely to jeopardize the continued existence of any species proposed to 

be listed under FESA or result in the destruction or adverse modification of critical habitat proposed to be 

designated for such species (16 USC Section 1536[3], [4]). Therefore, project-related impacts to these 

species, or their habitats, would be considered significant and require mitigation. 

Under FESA, critical habitat may be designated by the Secretary of the Interior for any listed species. 

The term "critical habitat" for a threatened or endangered species refers to the following: 

(i) the specific areas within the geographical range of the species at the time it is listed that contains 

suitable habitat for the species, which may require special management considerations or 

protection; and 

(ii) the specific areas outside the geographical range of the species at the time it is listed that contains 

suitable habitat for the species and is determined to be essential for the conservation of the 

species. 

Under Section 7 of the FESA, all federal agencies (including USFWS and NMFS) are required to ensure 

that any action they authorize, fund, or carry out will not likely jeopardize the continued existence of a 

listed species or modify their critical habitat. 

SANTA ROSA PLAIN CONSERVATION STRATEGY

In addition to designating critical habitat for federally listed species, the USFWS also creates, 

coordinates, and implements species-specific recovery plans and enters into specialized conservation 

agreements with local jurisdictions in order to prevent further decline of federally listed species. 

Recovery plans are designed to ensure that continued decline of federally listed species is arrested and 

threats are removed or reduced so that long-term survival of species in the wild is achieved. The ultimate 

goal of recovery plans is to stabilize, recover, and ultimately delist endangered and threatened species. 

Specialized conservation agreements are cooperative approaches to species protection that have 

developed by appropriate government agencies and other interested parties (e.g., conservation groups, 
Technical Memorandum 

Analytical Environmental Services 7 Lytton Residential Development Project 

October 2010 Technical Memorandum: Botanical Surveys 

private landowners, and special-interest foundations) that enable planned land uses to occur within the 

range of federally listed species. These agreements are intended to expedite the environmental review 

process by identifying major conservation goals, specific areas that provide crucial habitat for listed 

species, and establishing specific mitigation requirements for the region as a whole versus evaluating and 

establishing such parameters on a project by project basis. 

The project site is at the northern end of the study area of the Santa Rosa Plain Conservation Strategy 

(Conservation Strategy; Brauner et al., 2005). This Conservation Strategy created a long-term program to 

mitigate potential adverse effects from future development on species listed as endangered by the Federal 

Government that occur only in the Santa Rosa Plain. Endangered species specifically addressed in the 

Conservation Strategy are the California tiger salamander (Ambystoma californiense; Sonoma 

population), Burke’s goldfield (Lasthenia burkei), Sonoma sunshine (Blennosperma bakeri), Sebastopol 

meadowfoam (Limnanthes vinculans), and many-flowered navarretia (Navarretia leucocephala ssp. 

plieantha). The program will contribute to the recovery of these listed species within Sonoma County 

and to the conservation of their sensitive habitats. The project site falls outside the known range of CTS 

(USFWS, 2005a). However, it is within the range of the four listed plant species that are known to occur 

on the Santa Rosa Plain. As such, determinant-level protocol surveys are required. In order to 

substantiate negative findings for the four listed plant species, the Conservation Strategy requires a 

minimum of two years of negative protocol survey results for future permitted actions. The protocol 

requires that at least three separate floristic surveys be conducted during the duration of the growing 

season within the project site for two consecutive years and that each one of these three floristic surveys 

be conducted at a time when at least one of the four listed plant species is identifiable (i.e., blooming) at a 

local reference site. 

Additional information regarding permitting requirements is available in a Programmatic Consultation 

for U.S. Army Corps of Engineers (USACE) 404 Permitted Projects that May Affect Four Endangered 

Plant Species on the Santa Rosa Plain, California (File Number 223420N) (USFWS, 2007). USFWS 

requires mitigation for impacted aquatic features that constitute suitable habitat for the four listed plant 

species (i.e., wetland features that are not occupied by the four listed plant species) and the mitigation 

ratios vary according to whether or not presence of these plant species is documented, assumed, or 

substantiated-negative. By definition, suitable habitat for the four listed plant species includes suitable 

vegetative conditions in combination with specified topographic and hydrologic conditions. Vegetative 

conditions such as areas that support vernal pool indicator species and seasonal wetland areas where 

weedy grasses contribute less than 90 percent of the relative vegetation cover must be present (CH2M 

Hill, 1998). These vegetative conditions must occur in combination with one or more topographic and 

hydrologic conditions: the wetland area has not been entirely filled such that the wetland no longer floods 

or ponds and the original topography no longer exists, the wetland has an outlet barrier or occurs in 

depressional terrain, or the wetland contains surface water during the rainy season in a normal rainfall 

year for seven or more consecutive days (CH2M Hill, 1998).

Analytical Environmental Services 8 Lytton Residential Development Project 

October 2010 Technical Memorandum: Botanical Surveys 

2.2 STATE

The California Department of Fish and Game (CDFG) implements state regulations pertaining to fish and 

wildlife and their habitat. The California Endangered Species Act (CESA) of 1970 (California Fish and 

Game [CFG] Code Section 2050 et seq., and CCR Title 14, Subsection 670.2, 670.51) prohibits the take 

(interpreted to mean the direct or indirect harm or killing of a species) of species listed under CESA (14 

CCR Subsection 670.2, 670.5). A CESA permit must be obtained if a project will result in the take of 

listed species, either during construction or over the life of the project. Under CESA, CDFG is 

responsible for maintaining a list of threatened and endangered species designated under state law (CFG 

Code 2070). CDFG also maintains lists of species of special concern, which serve as “watch lists.” 

Pursuant to requirements of CESA, an agency reviewing a proposed project within its jurisdiction must 

determine whether any state listed species may be present in the study area and determine whether the 

proposed project will have a potentially significant impact upon such species. Project-related impacts to 

species on the CESA list and species of special concern would be considered significant and require 

mitigation. 

The California Native Plant Society (CNPS) publishes and maintains an Inventory of Rare and 

Endangered Vascular Plants of California in both hard copy and electronic versions. Plants on Lists 1A, 

1B, and 2 of the CNPS Inventory consist of plants that may qualify for listing, and the CDFG 

recommends they be addressed in CEQA projects (CEQA Guidelines Section 15380). However, a plant 

need not be in the Inventory to be considered a rare, threatened, or endangered species under CEQA. 

The California Environmental Quality Act of 1970 (Subsections 21000-21178) requires that CDFG be 

consulted during the CEQA review process regarding impacts of proposed projects on rare or endangered 

species. These “special-status” species are defined under CEQA Guidelines subsection 15380(b) and (d) 

as those listed under FESA and CESA, and species that are not currently protected by statute or 

regulation, but would be considered rare, threatened, or endangered under these criteria, or by the 

scientific community. Therefore, species that are considered rare or endangered are addressed in this 

study regardless of whether they are afforded protection through any other statute or regulation. 

Although threatened and endangered species are protected by specific federal and state statutes, CEQA 

Guidelines Section 15380(d) provides that a species not listed on the federal or state list of protected 

species may be considered rare or endangered if the species can be shown to meet certain specified 

criteria. These criteria have been modeled after the definition in the FESA and the section of the 

California Fish and Game Code dealing with rare or endangered plants and animals. Section 15380(d) 

allows a public agency to undertake a review to determine if a significant effect on species that have not 

yet been listed by either the USFWS or CDFG (i.e., candidate species) would occur. Thus, CEQA 

provides an agency with the ability to protect a species from a project’s potential impacts until the 

respective government agencies have an opportunity to designate the species as protected, if warranted.

2.3 LOCAL

Several of the goals and policies within the Sonoma County General Plan (Plan) regarding biological 

resources apply directly to the proposed project (County of Sonoma, 1989). The following elements of 

the Plan have components that may generally pertain to the proposed project: Land Use Element, Open 

Space Element, Agricultural Resources Element, and Resource Conservation Element. 

In addition to the Plan, Sonoma County also has a body of regulations collectively called the Sonoma 

County Code that is responsible for issuing permits to implement the goals and policies of the Plan and is 

enforceable by law. Several articles within the Sonoma County Code may generally pertain to the 

proposed project and include such things as tree protection ordinances, oak tree preservation, heritage tree 

protection, etc. 

3.0 METHODOLOGY 

For the purposes of this report, the study area includes the entire Lytton residential project site (refer to

Figure 3). 

3.1 PRELIMINARY RESEARCH

Prior to conducting the floristic surveys AES staff reviewed the following resources: 

• Aerial photographs of the project site, 

• USGS “Healdsburg, CA” 7.5-minute topographic quadrangle (USGS, 1993), 

• Online Soil Survey of Sonoma County, California (USDA/NRCS, 2008),A USFWS list of 

federally listed special-status species with potential to occur within Sonoma County, the 

“Healdsburg, CA” 7.5-minute topographic quadrangle and the eight surrounding quadrangles 

(“Jimtown,” “Mount Saint Helena,” “Mark West Springs,” “Santa Rosa,” “Sebastopol,” “Camp 

Meeker,” “Guerneville,” and “Geyserville”) (USFWS, 2009; query date December 24, 2009), 

• A California Natural Diversity Database (CNDDB) list of state and federally listed special-status 

species with potential to occur within the “Healdsburg, CA” 7.5-minute topographic quadrangle 

and the surrounding eight quadrangles (CDFG, 2003; query date December 24, 2009), 

• A CNDDB map of state and federally listed special-status species that have been documented 

within a five-mile radius of the project site (CDFG, 2003; mapped June 2010), and 

• A CNPS list of special-status plant species with potential to occur within the “Healdsburg, 

California” 7.5-minute topographic quadrangle and the surrounding eight quadrangles listed 

above (CNPS, 2009; query date December 24, 2009). 

The USFWS, CNDDB, and CNPS database research lists of regionally occurring special-status species 

are included for reference purposes in Appendix A. 
Technical Memorandum 

Analytical Environmental Services 10 Lytton Residential Development Project 

October 2010 Technical Memorandum: Botanical Surveys 

A complete list of all of the regionally occurring special-status species reported in the scientific database 

queries was compiled for the project site (Appendix B). An analysis to determine which of these specialstatus species have the potential to occur within the project site was conducted. The habitat requirements 

for each regionally occurring special-status species were assessed and compared to the type and quality of 

habitats observed on-site during the field surveys. Several regionally occurring special-status species 

were eliminated due to lack of suitable habitat within the project site, range of elevation, lack of suitable 

soil/substrate, and/or distribution. The analysis was also based on reviews of resource agency materials, 

applicable scientific literature, aerial photography of the project site, topographic maps of the project site, 

and other pertinent local information. Special-status plant species that warrant discussion and those 

determined to have the potential to occur within the project site are addressed in Section 4.4. Specialstatus plant species determined not to have potential to occur within the project site are not discussed 

further in this report. 

3.2 FLORISTIC SURVEYS

AES staff conducted the floristic surveys within the project site in accordance with the Guidelines 

presented in Appendix D of the Conservation Strategy (Brauner et al., 2005). The field surveys were 

conducted on foot and AES staff surveyed the entire project site in order to view all the habitat types on 

the project site. The field surveys were conducted during the appropriate periods of identification for all 

of the potentially occurring special-status plant species. All visible plant species were noted and 

identified to the lowest possible taxonomic level, which is required for accurate identification and 

reporting. Plant species identification, nomenclature, and taxonomy followed Hickman (1993a and 

1993b) and Best (1996). 

3.3 SURVEY CHRONOLOGY

Special-status plant surveys were conducted within the original project parcel APN 066-300-031 on April 

5, April 30, and May 30, 2007. This survey effort met the requirements of the Conservation Strategy for 

the first year of floristic surveys within APN 066-300-031. The Tribe then purchased a second parcel, 

APN 066-300-033. Special-status plant surveys were conducted within both parcels (i.e., APN 066-300-

031 and APN 066-300-033) on March 27, April 18, and May 27, 2008. This survey effort met the 

requirements of the Conservation Strategy for the second year of floristic surveys within APN 066-300-

031 and for the first year of floristic surveys within APN 066-300-033. In 2009, AES completed the 

remaining floristic surveys required by the Conservation Strategy for APN 066-300-033. These surveys 

were conducted on March 24, April 20, and May 14, 2009. AES concurrently conducted first-year 

floristic surveys in 2009 on newly acquired APNs 066-300-028, 066-191-017, 066-191-018, 066-191-

020, and 066-191-022. Second-year floristic surveys were conducted on these parcels as well as new 

APNs 066-300-23, 066-300-017, 066-191-016, 066-191-019 and 066-191-021 on April 9, May 10, June 

8, and July 8, 2010. Two additional parcels, APNs 066-050-040 and 066-050-047 obtained in May 2010, 

received first-year floristic surveys on June 10 and July 8, 2010. The status of floristic surveys for each 

project parcel is shown in Table 2 and the parcels are shown on an aerial map in Figure 3. Surveys in 
Technical Memorandum 

Analytical Environmental Services 11 Lytton Residential Development Project 

October 2010 Technical Memorandum: Botanical Surveys 

2010 were conducted by AES Botanist Adrienne Edwards, PhD, with the assistance of AES biologists 

Ona Alminas and Jessica Griggs (for qualifications, see Appendix C). AES staff will conduct the final 

growing season floristic surveys for the second required consecutive year on these parcels in 2011. No 

federal special-status plant species have been observed within the project site during any of the floristic 

surveys that AES staff has conducted to date. Completely substantiated negative results are anticipated, 

given the habitats and results found on the parcels thus far.

Vegetation communities (assemblages of plant species growing in areas of similar biological and 

environmental factors), were classified using the CDFG Terrestrial Natural Communities of California 

system, or “Holland type” (Holland, 1986), and where applicable, detailed by Vegetation Series 

(distinctive associations of plants, described by dominant species and particular environmental setting) 

using the Manual of California Vegetation (Sawyer et al., 2009), which is based on the National 

Vegetation Classification System. Wetlands and other aquatic habitats were classified using USFWS 

National Wetlands Inventory/Classification System for Wetland and Deepwater Habitats, or “Cowardin 

class” (Cowardin et al., 1979) and criteria defined in the 1987 Wetland Delineation Manual by the 

USACE. 

Locations of species’ occurrences and habitat boundaries within the study area were recorded on color 

aerial photographs (scale 1”=600’). The boundaries of potentially jurisdictional waters within the study 

area were identified in the field and recorded on color aerial photographs. The results were digitized to 

produce the final habitat map (Figure 5). 

3.4 REFERENCE POPULATIONS

The Conservation Strategy Guidelines require that the floristic surveys be conducted at times that 

coincide with periods when the four Santa Rosa Plain listed plant species are identifiable at a local 

reference site (Brauner et al., 2005). AES staff gathered information regarding known locations of these 

species from the CNDDB. Reference populations were available for three of the four listed plant species 

addressed in the Conservation Strategy: Burke’s goldfields, Sonoma sunshine and Sebastopol 

meadowfoam. The only non-hybrid population of many-flowered navarretia known in Sonoma County is 

in the Santa Rosa Plain, but it occurs on property within a private gated community. Owing this, the

Analytical Environmental Services 13 Lytton Residential Development Project 

October 2010 Technical Memorandum: Botanical Surveys 

navarretia population was not accessible for reference visit. Reference sites for the other species were 

visited early in the morning prior to conducting each of the special status plant surveys listed in Table 2. 

 

Two other species listed as federal endangered have the potential to occur on the project site but are not 

specifically covered under the Conservation Strategy. A reference population of Sonoma alopecurus 

(Alopecurus aequalis var. sonomensis; federal endangered), a species not addressed in the Conservation 

Strategy, was not readily available. According to the CNDDB (CDFG, 2003), none of the Sonoma 

populations have been verified since 1987, with the exception of one verified in 1997; all appeared to be 

declining or missing at that time. For this reason, a reference site for this species was not utilized (see 

Section 4.4 for more information). The addition of APN 066-191-022 (which contains a perennial 

drainage) to the project site, resulted in potential for the federal and state endangered Pitkin Marsh lily 

(Lilium pardalinum ssp. pitkinense) to occur within the project site. A reference population of Pitkin 

Marsh lily was visited prior to conducting a focused survey for this species within the project site on June 

29, 2009. Lilies are readily recognizable by the shape and arrangement of their leaves, even if the flowers 

are browsed off. 

Specific details regarding the phenological state of the plant species observed during the reference site 

visits are discussed in Section 4.4. 

4.0 RESULTS 

This section summarizes the results of the floristic surveys that were conducted within the project site and 

provides further analysis of the data collected in the field. Discussions regarding the terrestrial and 

aquatic habitat types on-site and information regarding the target special-status plant species are presented 

below. 

4.1 ENVIRONMENTAL SETTING 

The project site is located in central Sonoma County, within the Russian River Valley. Sonoma County 

has a Mediterranean climate regime characterized by hot, dry, sunny summers and cool, rainy winters. 

This type of climate is also referred to as an etesian climate. Offshore winds and fog from the Pacific 

Ocean are common and these factors tend to moderate the climate in Sonoma County. Evening 

temperatures are frequently much cooler than midday temperatures and mornings are prone to coastal fog. 

The mean annual temperature range near the Town of Healdsburg is approximately 46° to 74° Fahrenheit 

(F). The average annual precipitation near the Town of Healdsburg is approximately 42 inches, with a 

maximum of approximately 8.81 inches during the month of January (WRCC, 2007). 

The project site is composed of gently rolling terrain and is situated at elevations that range from 

approximately 29 to 67 meters (95 to 220 feet) above mean sea level. The Russian River Valley falls 

within climate Zone 14 “Ocean-influenced Northern and Central California.” Climate Zone 14 includes 
Technical Memorandum 

Analytical Environmental Services 14 Lytton Residential Development Project 

October 2010 Technical Memorandum: Botanical Surveys 

inland areas with oceanic or other cold air influence. This climate zone is a linear region that runs from 

Humboldt County to Santa Barbara County (Hickman, 1993a). The local and regional geology is within 

the Outer North Coast Range (NCoRo) geographic subdivision of California. The NCoRo is 

characterized by redwood, mixed-ever-green, and mixed-hardwood forests and by very high rainfall. The 

NCoRo subdivision is part of the larger Northwestern (NW) geographic division, which occurs within the 

larger California Floristic Province (Ca-FP), thus is equivalent to “cismontane” as often cited in other 

scientific texts (Hickman, 1993a). 

The project site is situated in a rural residential/agricultural setting near the Town of Windsor, 

approximately one mile west of the town center. APNs 066-191-017, 066-191-018, 066-191-022, 066-

050-040 and 066-050-047, which comprise approximately 41.23 acres of the project site, are within the 

sphere of influence of the Town of Windsor (Table 1). Specific surrounding land uses include rural 

residences, agriculture (vineyards and pastures), and undeveloped parcels. The project site is 

predominantly undeveloped and uncultivated. However, several abandoned and/or occupied residences 

and associated structures are located on-site. Approximately twelve existing residences and other 

associated buildings are located within APNs 066-300-033, 066-300-028, 066-191-020, 066-191-017, 

066-300-023, 066-300-017, 066-191-016, 066-191-019, 066-191-021 and 066-050-040. 

4.2 SOILS 

According to the U.S. Department of Agriculture (USDA), Natural Resources Conservation Service 

(NRCS) online Soil Survey for Sonoma County, seven soil units, or types, have been mapped within the 

project site (NRCS, 2008). These include: (AeA) Alluvial Land, clayey; (AgE) Arbuckle gravelly sandy 

loam, 15 to 30 percent slopes; (Cgc) Clough gravelly loam, 2 to 9 percent slopes; (FaD) Felta very 

gravelly loam, 5 to 15 percent slopes; (FaF) Felta very gravelly loam, 30 to 50 percent slopes; (HtC) 

Huichica loam, 2 to 9 percent slopes; and (SkD) Spreckels loam, 9 to 15 percent slopes. (AeA) Alluvial 

Land, clayey is the only one of the seven soil units that occur on-site that contains listed hydric inclusions 

and/or components. It is composed of alluvial land components, which include soils that are frequently 

flooded for long or very long duration during the growing season (NRCS, 2008). 

4.3 HABITAT TYPES 

The project site contains a variety of terrestrial and aquatic habitat types. Six terrestrial habitats were 

identified on-site and these include: annual grassland, mixed oak woodland, oak savannah, mixed 

riparian, pasture, and ruderal/developed. Six aquatic habitat types were observed on-site including: 

seasonal wetland, seasonal wetland swale, stock pond, isolated pit, perennial stream and ephemeral 

drainage. A map that illustrates the various habitat types within the project site is presented as Figure 4 

and they are further discussed below.

ANNUAL GRASSLAND

Annual grassland habitat is scattered in small patches throughout the mixed oak woodland and oak 

savannah habitats on the project site, as well as a grassy hillside within APN 066-300-023 of 

approximately one acre. Trees are largely absent within this community type and it is generally 

dominated by non-native annual grasses and forbs. Native grasses found commonly in these areas 

included California oatgrass (Danthonia californica), blue wildrye (Elymus glaucus), and purple 

needlegrass (Nassella pulchra). Non-native grasses common within this habitat type included vernal 

grass (Anthoxanthum aristatum), wild oat (Avena fatua), quaking grass (Briza maxima), hedgehog dogtail grass (Cynosurus echinatus), annual rabbit-foot grass (Polypogon monspeliensis), small patches of 

medusa-head grass (Taeniatherum caput-medusae), and rat-tail vulpia (Vulpia myuros). Non-native 

brome grasses (Bromus spp.) were notably uncommon in these areas. Native forbs commonly observed 

were harvest brodiaea (Brodiaea elegans), soap plant (Chlorogalum pomeridianum var. pomeridianum), 

blue dicks (Dichelostemma capitatum), plantain (Plantago erecta), mules ears (Wyethia glabra), Ithuriel’s 

spear (Triteleia laxa), sun cup (Camissonia ovata), buttercup (Ranunculus californicus) and butter and 

eggs (Triphysaria eriantha). Non-native forbs commonly observed were bur chervil (Anthriscus 

caucalis), filaree (Erodium botrys), Klamath weed (Hypericum perforatum), sanicle (Sanicula 

crassicaulis), common sow thistle (Sonchus oleraceous), torilis (Torilis arvensis), and vetch species 

(Vicia sativa and V. villosa). 

MIXED OAK WOODLAND

Mixed oak woodland is the dominant habitat type within the project site. The overstory of this 

community is composed of mature blue oak (Quercus douglasii), black oak (Quercus kellogii), coast live 

oak (Quercus agrifolia), and madrone (Arbutus menziesii) trees. More specifically, Black Oak Forest 

Alliance (Sawyer et al., 2009) is found on ridgetops and slopes in the northwest quadrant of APN 066-

300-031, as well as APNs 066-300-033 and 066-300-028. The Black Oak Forest Alliance is dominated 

by black oak (> 50 percent) in the canopy, with madrone and coast live oak as subdominants. Nonriparian woodlands elsewhere on the project site are Blue Oak Woodland Alliance (Sawyer et al., 2009), 

where blue oak is dominant (> 50 percent) in the tree canopy, with coast live oak subdominant. Shrub 

and vine species observed within the oak woodlands on the project site include: poison oak 

(Toxicodendron diversilobum), Himalayan blackberry (Rubus armeniacus), coyote brush (Baccharis 

pilularis), scotch broom (Cytisus scoparius), pipevine (Aristolochia californica), and honeysuckle 

(Lonicera hispidula). The understory of this community is dominated by annual grasses and forbs, 

observed species included annual vernal grass, wild oat, quaking grass, hedgehog dog-tail grass, soap 

plant, filaree, Klamath weed, skunkweed (Navarretia squarrosa), blue-eyed grass (Sisyrinchium bellum), 

torilis, rose clover (Trifolium hirtum), and bird’s beak (Cordylanthus pilosus). 

OAK SAVANNAH

The oak savannah habitat type within the project site is also Blue Oak Woodland Alliance (Sawyer et al., 

2009), but the overall density of trees is much lower, with larger annual grassland openings. The plant 
Technical Memorandum 

Analytical Environmental Services 17 Lytton Residential Development Project 

October 2010 Technical Memorandum: Botanical Surveys 

species composition is the same as described for mixed oak woodland above, with the exception of the 

shrub/vine layer. The shrub/vine stratum is largely absent within this community. 

MIXED RIPARIAN

Mixed riparian habitat occurs along several of the drainages that were mapped within the project site. 

Plant species observed in the tree layer of this community include Valley oak (Quercus lobata), coast live 

oak, willows (Salix spp.), and Fremont’s cottonwood (Populus fremontii). The dominant plant species 

observed within the shrub/vine layer of this community are Himalayan blackberry and poison oak. Other 

plant species observed within the herbaceous layer of this community include: ryegrass (Lolium 

multiflorum), little quaking grass (Briza minor), and blue wildrye. 

PASTURE

Pasture and developed areas dominate the eastern portion of the project site. Pasture south of Windsor 

River Road appears to be used primarily for horses, and pasture north of Windsor Road has been used 

primarily for cattle in recent years. Trees and shrubs are sparse within this community, although, remnant 

stands of blue oak woodland persist and there are a few stands of planted non-native shade trees. Pasture 

differs from annual grassland habitat in overall plant species composition and the distribution of native 

species, which reflects more intensive management through periodic plowing and seeding. Occasional 

natives observed on-site included California oatgrass and purple needlegrass in pastures on the north side 

of Windsor River Road. Pastures on the south side of Windsor River Road contained a greater cover of 

weedy forbs and non-native grasses. Dominant non-native grasses included: wild oat, quaking grass, 

ripgut brome, soft brome, barley (Hordeum murinum), ryegrass, medusa-head grass, and rat-tail vulpia. 

Non-native forbs that were common in the pasture included filaree, bur chervil (Anthriscus caucalis), 

torilis, prickly sow thistle (Sonchus asper), Shamrock clover (Trifolium dubium), rose clover, vicia 

species, pineapple weed (Chamomilla suaveolens), field mustard (Brassica rapa), black mustard 

(Brassica nigra), Shepard’s purse (Capsella bursa-pastoris), bindweed/morning glory (Convolvulus 

arvensis), cut-leaved geranium (Geranium dissectum), shortpod mustard (Hirschfeldia incana), 

perennial/rough cat’s ear (Hypochaeris radicata), Spanish clover (Lotus purshianus), yellow wild radish 

(Raphanus raphanistrum) and sheep sorrel (Rumex acetosella). The following native forbs observed 

within pasture habitat include: soap plant, buttercup, sun cup, butter and eggs, dove weed (Eremocarpus 

setigerus), bicolored lupine (Lupinus bicolor), and bracted popcorn flower (Plagiobothrys bracteatus). 

 

RUDERAL/DEVELOPED

The areas classified as ruderal/developed habitat within the project site include all existing residences and 

structures, any landscaped areas, roads and parking areas, and otherwise disturbed regions. Non-native 

landscape plants observed in these areas included English walnut (Juglans regia), London plane tree 

(Platanus x acerifolia), Eucalyptus (Eucalytpus spp.), fig (Ficus carica), pomegranate (Punica 

granatum), apple (Malus spp.), plum (Prunus spp.), heavenly bamboo (Nandina domestica), periwinkle 

(Vinca major), and English ivy (Hedera helix). Weedy forbs observed within this habitat type included 

non-native sweet fennel (Foeniculum vulgare), mayweed (Anthemis cotula), bindweed, bristly oxtongue

Analytical Environmental Services 18 Lytton Residential Development Project 

October 2010 Technical Memorandum: Botanical Surveys 

(Picris echioides), shortpod mustard, bur clover (Medicago polymorpha), filaree, English plantain 

(Plantago lanceolata), prostrate knotweed (Polygonum arenastrum), ripgut brome, wild oat, harding 

grass (Phalaris aquatica) and various lawn grasses. 

EPHEMERAL DRAINAGE

Ephemeral drainages are linear features that exhibit an OHWM and have a clearly defined bed and bank. 

They are seasonal features that typically convey rainwater and surface runoff flows seasonally and for 

short time periods. The channels within ephemeral drainages tend to be largely unvegetated due to the 

scouring effects of flowing water. If plants do occur within ephemeral drainages, they tend to occur 

within the upper limits of the drainage or in areas where sediment has deposited that can function as a 

plant substrate. Unlike intermittent drainages, ephemeral drainages are not typically influenced by 

groundwater. Nine ephemeral drainages were mapped within the project site (AES, 2010). Plant species 

observed within these feature types include: blue oak, coast live oak, madrone, ryegrass, torilis, shortpod 

mustard, sedge (Carex densa), tall flatsedge (Cyperus eragrostis), poverty rush (Juncus tenuis), 

pennyroyal (Mentha pulegium), ryegrass, fiddle dock (Rumex pulcher), and hedge nettle (Stachys 

ajugoides). 

ISOLATED PIT

The isolated pits within the project site are relatively deep holes that were excavated within uplands. 

These features are round to rectangular in shape and the excavated dirt from within them is piled right 

beside them. Two isolated pits were mapped within the project site (AES, 2010). The two isolated pits 

may have functioned as watering holes for cattle, test percolation pits, or potential sites for trash disposal. 

Creeping spikerush (Eleocharis macrostachya) was the dominant plant species observed within the 

isolated ponds on-site. 

SEASONAL WETLAND

Seasonal wetlands are typically closed, depressional features that are ephemerally wet due to the 

accumulation of surface runoff and rainwater collection within low-lying areas. The length of inundation 

tends to be relatively short and seasonal wetlands are typically dominated by non-native, hydrophytic 

plant species. Seven seasonal wetlands were mapped within the project site (AES, 2010). Plant species 

observed within the seasonal wetlands included blue oak, ryegrass, fiddle dock, quaking grass, poverty 

rush, hedgehog dog-tail grass, pennyroyal, tall flatsedge , Bermuda grass (Cynodon dactylon), annual 

vernal grass, curly dock (Rumex crispus), soft brome, Mediterranean barley, white water buttercup 

(Ranunculus aquatilis) and little quaking grass. 

SEASONAL WETLAND SWALE

Seasonal wetland swales are typically linear-shaped features that lack a clearly defined bed and bank and 

do not exhibit an OHWM. The length of inundation within seasonal wetland swales is relatively short 

and seasonal. These features primarily carry surface runoff and rainwater from areas of higher elevation 
Technical Memorandum 

Analytical Environmental Services 19 Lytton Residential Development Project 

October 2010 Technical Memorandum: Botanical Surveys 

to areas of lower elevation. Three seasonal wetland swales were mapped within the project site (AES, 

2010). Plant species observed within the seasonal wetland swale mapped within the project site include: 

valley oak, pennyroyal, tall flatsedge, ryegrass, cut leaved geranium, and curly dock. 

STOCK POND

Stock ponds are typically man-made pond features which usually have a clearly defined bed and bank and 

OHWM. Two stock ponds occur within the northern two parcels of the project site (AES, 2010). 

Dominant plant species observed within the stock ponds include spikerush and semaphore grass 

(Pleuropogon californicus); rye grass and wild oats were dominant along upland slopes. 

PERENNIAL DRAINAGE

Perennial drainages are linear features that exhibit an OHWM, have a clearly defined bed and bank, are 

typically inundated year-round, and have some degree of ground water contribution. A single perennial 

drainage was observed within the project site along the eastern boundary (AES, 2010). Plant species 

observed within the riparian corridor associated with the perennial drainage on-site include Valley oak, 

blue oak, black oak, willows, Himalayan blackberry (Rubus discolor) and poison oak. Plant species were 

largely absent within the actual channel due to the scouring effect of flowing water. 

4.4 SPECIAL-STATUS PLANT SPECIES

For the purposes of this report, special-status is defined as those plant species that are of management 

concern to state and/or federal resource agencies, and includes those plant species that are: 

• Listed as endangered, threatened, or candidate for listing under the FESA; 

• Listed as endangered, threatened, rare, or proposed for listing, under the CESA; 

• Designated as endangered or rare, pursuant to California Fish and Game Code (Section 

1901); 

• Designated as fully protected, pursuant to California Fish and Game Code (Section 3511, 

Section 4700, or Section 5050); 

• Designated as species of special concern by CDFG; and 

• Plants that meet the definitions of rare, threatened, or endangered under CEQA, including 

plants listed by CNPS to be “rare, threatened, or endangered in California” (Lists 1A, 1B, 

and 2). Local or regional agencies may consider plant species that CNPS believes require 

additional information (List 3) and plant species that have been placed on a watch list (List 

4) by CNPS. 

All occurrences of special-status plant species and sensitive habitats from the CNDDB within a five-mile 

radius of the project site were plotted on a map using geographic information systems (GIS) software and 

this map is presented as Figure 5. As discussed in Section 3.1, an analysis was conducted to determine 

which of these regionally occurring special-status plant species has the potential to occur within the

4.5 REFERENCE POPULATIONS

As mentioned in Section 3.3, the Conservation Strategy Guidelines require that floristic surveys be 

conducted at times that coincide with when at least one of the four Santa Rosa Plain listed plant species is 

accurately identifiable on a local reference site (Brauner et al., 2005). AES staff utilized reference 

populations whenever feasible to satisfy this requirement. The first of these reference sites is located 

southwest of the City of Santa Rosa, at the “elbow” of Todd Road, near where it intersects with Llano 

Road in Sonoma County, California. Sonoma sunshine (Occurrence No. 8), Burke’s goldfields 

(Occurrence No. 1), and Sebastopol meadowfoam (Occurrence No. 1) occur at this site (CDFG, 2003). 

The second reference site is located at the Alton Road Vernal Pool Preserve, northwest of the City of 

Santa Rosa, approximately one half mile west of Fulton Road, along the south side of Alton Road in 

Sonoma County, California. Burke’s goldfields (Occurrence No. 25) and Sebastopol meadowfoam 

(Occurrence No. 21) are located at this site (CDFG, 2003). Sonoma sunshine also occurs at this location. 

It was not feasible or practical to visit a reference site for many-flowered navarretia because there was no 

access to non-hybrid populations nearby (see Section 3.3). The phenological state of the species covered 

by the Conservation Strategy at reference sites for Sonoma sunshine, Burke’s goldfields, and Sebastopol 

meadowfoam, as well as the similarity of physiographic control between reference sites and surveyed 

sites is provided in Table 3. The extent of pooling followed general patterns expected in relatively dry 

(ie, 2007 through 2009) versus wetter years (2010). 

Sonoma sunshine was observed in full bloom and thousands of individuals were seen by AES staff at the 

Todd Road location on April 5 and 30, 2007, March 26 and April 18, 2008, and March 24 and April 20, 

2009. Significantly fewer individuals were evident in 2010, likely due to a long, cool spring and late, 

regular rains that repeatedly flooded the wetlands, submerging the plants. Sonoma sunshine was observed 

at the Alton Road reference site on the same dates. During the reference visits to these locations during 

the month of May (i.e., May 30, 2007, May 27, 2008, and May 14, 2009), Sonoma sunshine had begun to 

go to seed at both of the reference sites. However, several flowering heads were observed in an open 

state and this species was still readily identifiable. The 2010 growing season was unusually cool, with 

late, almost weekly rains that caused multiple cycles of flooding and draw-down. No Sonoma sunshine 

plants could be found flowering on the April 9, 2010 visit. As shown in Table 3, Sonoma sunshine was 

not found at the Todd Road site and was delayed in flowering by at least a month at the Alton Road 

Vernal Pool Reserve in 2010 compared to the previous three years.

Generally, Burke’s goldfields began blooming later in the season than the other two plant species. 

Burke’s goldfields were observed in full bloom and thousands of individuals were viewed by AES staff at 

both of the reference site locations. When Sebastopol meadowfoam and Sonoma sunshine were seeding, 

Burke’s goldfields continued to bloom. This species was readily identifiable during the reference site 

visits conducted on April 30, 2007, April 18 and May 27, 2008, and April 20 and May 14, 2009. During 

the later reference site visits, insects had begun to eat the flowering heads and this species had begun to 

seed, but this species was still readily identifiable. In 2010, this species was not evident until the May 10 

visit. Burke’s goldfields was not found at the Todd Road site and was delayed in flowering by up to a 

month at the Alton Road Vernal Pool Reserve in 2010 compared to the previous three years. 

Sebastopol meadowfoam was also observed in full bloom and many individuals were seen by AES staff 

at the Todd Road location on April 5 and 30, 2007, March 26 and April 18, 2008, and March 24 and April 

20, 2009. This species was also observed at the Alton Road Vernal Pool Preserve on the same dates, 

however far fewer individuals occur at this location. More individuals of this species were observed 

during the 2009 floristic year at the Todd Road location than any of the previous years. As with Sonoma 

sunshine, this species began to seed and the blooms were generally past during the May (i.e., May 30, 
Technical Memorandum 

Analytical Environmental Services 26 Lytton Residential Development Project 

October 2010 Technical Memorandum: Botanical Surveys 

2007, May 27, 2008, and May 14, 2009) reference site visits. However, this species is readily identifiable 

by its leaves and a few of the heads still had the petals attached, though withered during the May 

reference site visits. In 2010, this species was not evident until the May 10 visit. Sebastopol 

meadowfoam was not found at the Todd Road site and was delayed in flowering by up to a month at the 

Alton Road Vernal Pool Reserve in 2010 compared to the previous three years. 

As was previously mentioned, AES staff visited one additional reference site to view the Pitkin Marsh lily 

on June 29, 2009 in the morning prior to conducting the focused survey for this species. The reference 

site is located southeast of the intersection of Bloomfield Road and Lone Pine Road in Sonoma County, 

California. This species occurs along an unnamed tributary to Blucher Creek and is within the greater 

Cunningham Marsh. Pitkin Marsh lily Occurrence Number 3 is located at this site (CDFG, 2003). 

No federal special-status plant species were observed within the project site during the floristic survey 

efforts. A comprehensive list of the plant species observed within the project site is included as 

Appendix C. 

TARGET PLANT SPECIES DESCRIPTIONS

Sonoma alopecurus (Alopecurus aequalis var. sonomensis) 

Grass Family (Poaceae) 

Federal Status – Endangered 

State Status – None 

Other – CNPS List 1B 

Sonoma alopecurus is a perennial grass known for having spikelets (excluding the awns) that are less than 

four millimeters (mm) long and straight (as opposed to bent) awns that barely exceed the body of the 

lemmas by zero to two mm. It occurs in freshwater marshes and swamps and riparian scrub habitats. 

This species occurs at elevations that range from five to 365 meters above mean sea level. Sonoma 

alopecurus is identifiable from May through July. The known range of this species includes Marin and 

Sonoma counties. This species Critical habitat has not been designated for this species and it does not 

have a recovery plan. The nearest documented occurrence of this species is located approximately five 

miles southwest of the site (CDFG, 2003). The aquatic features within the project site and the mixed 

riparian habitat were considered marginally suitable habitat for this species. Sonoma alopecurus was not 

observed during the floristic surveys, which were conducted within the appropriate period of 

identification for this species. 

Sonoma sunshine (Blennosperma bakeri) 

Sunflower Family (Asteraceae) 

Federal Status – Endangered 

State Status – Endangered 

Other – CNPS List 1B 
Technical Memorandum 

Analytical Environmental Services 27 Lytton Residential Development Project 

October 2010 Technical Memorandum: Botanical Surveys 

Sonoma sunshine is an annual herb with entire lower leaves, one- to three-lobed upper leaves, and ray 

flowers that have dark red stigmas. It occurs in mesic areas within valley and foothill grassland and 

vernal pool habitats at elevations from ten to 110 meters above mean sea level. This species is 

identifiable when flowering from March through May. Sonoma sunshine is endemic to Sonoma County. 

Critical habitat has not been designated for this species and it does not have a recovery plan. The nearest 

documented occurrence of this species is located approximately five miles southeast of the project site 

(CDFG, 2003). As previously discussed, a reference population of this species was observed at the Todd 

Road location. The aquatic features and the annual grassland habitat within the project site were 

considered suitable habitat for this species. Sonoma sunshine was not observed on-site during the 

floristic surveys, which were conducted within the appropriate bloom window for this species. 

 

Salt marsh owl’s clover (Castilleja ambigua ssp. ambigua)

Snapdragon Family (Scrophulariaceae) 

Federal Status – None 

State Status – None 

Other – CNPS 4.2 

Salt marsh owl’s clover is a many-branched, decumbent annual 10 to 30 centimeters high with yellowtipped bracts. It is found in coastal bluff scrub, coastal prairie, coastal scrub, marshes and swamps, valley 

and foothill grassland, and vernal pool margins. It is identifiable from May to November. It has been 

documented at elevations of 0 to 435 meters above mean sea level, in Alameda, Contra Costa, Del Norte, 

Humboldt, Mendocino, Marin, Napa, Santa Cruz, San Francisco (unverified), San Luis Obispo, San 

Mateo, Sonoma, as well as Oregon and Washington. This species is not documented within the CNDDB; 

however, CNPS recommends that List 3 and List 4 plant species be considered because their status may 

change and other local and/or regional regulations may require evaluation. The project site provides 

potential habitat for this species within the grassland habitats on site. Salt marsh owl’s clover was not 

observed on the project site during the biological surveys. 

Pappose tarplant (Centromadia parryi ssp. parryi) 

Sunflower Family (Asteraceae) 

Federal Status – None 

State Status – None 

Other – CNPS 1B 

Pappose tarplant is an annual with radiate heads, phyllaries in one series subtending the ray flowers and 

the yellow ray and disc flowers have yellow anthers. It generally occurs in alkaline soils in chaparral, 

coastal prairie, meadows and seeps, marshes and swamps (coastal salt), and valley and foothill grassland 

habitats that are vernally mesic. It is identifiable from May to October. Extant records exist in Alameda, 

Contra Costa, Monterey, Santa Clara, San Luis Obispo and San Mateo counties at elevations from two to

Many-flowered navarretia (Navarretia leucocephala ssp. plieantha)

Phlox Family (Polemoniaceae) 

Federal Status – Endangered 

State Status – Endangered 

Other – CNPS List 1B 

Many flowered navarretia is an annual herb that occurs in vernal pool habitats. Many-flowered navarretia 

(like Baker’s navarretia) is differentiated from the other subspecies because it has a corolla that is greater 

than or equal to the calyx and calyx lobes that are generally entire (as opposed to toothed). However, this 

subspecies (ssp. plieantha) has low, spreading branches (as opposed to erect and ascending), and bluetinged corollas. This species has an affinity for volcanic ash flow-derived soils. It occurs at elevations 

from 30 to 650 meters above mean sea level and it blooms from May through June. This species is found 

only in Lake and Sonoma counties. Critical habitat has not been designated for this species. However, it 

is included in the Recovery Plan for Vernal Pool Ecosystems of California and Oregon (USFWS, 2005). 

There are only two occurrences in Sonoma County and five in Lake County, representing the entire 

geographic range of the species. The nearest documented occurrence of this species is located 

approximately 2.5 miles southeast of the project site (Occurrence No. 9; CDFG, 2003). This occurrence 

may be hybridizing with subspecies leucocephala (CDFG, 2003). The other Sonoma County record 

(Occurrence No. 10) is contained within a gated community to which we could not gain access. The 

aquatic features (i.e., seasonal wetlands) within the project site are considered marginally suitable habitat 

for this species. Many-flowered navarretia was not observed within the project site during the floristic 

surveys, which were conducted within the appropriate period of identification for this species.

5.0 SUMMARY/CONCLUSIONS 

On behalf of the Lytton Tribe, AES has conducted a series of botanical surveys throughout the 

approximately 124.12-acre Lytton residential development project site. AES determined that the project 

site contains potentially suitable habitat for ten regionally occurring special-status species. The target 

species for the floristic surveys include: Sonoma alopecurus, Sonoma sunshine, pappose tarplant, dwarf 

downingia, fragrant fritillary, seaside tarplant, legenere, Burke’s goldfields, Pitkin Marsh lily, Sebastopol 

meadowfoam, marsh microseris, Baker’s navarretia, and many-flowered navarretia. Surveys were 

comprehensive, and all species encountered were identified to the lowest possible taxonomic level. AES 

also targeted CNPS List 3 and 4 species not covered under FESA or CEQA, but that may have the 

potential in the future to be listed, including Johnny-nip, California bottlebrush grass, bristly leptosiphon, 

redwood lily, harlequin lotus, Gairdner’s yampah, and Lobb’s aquatic ranunculus. Only two CNPS 4.2 

plants were observed within the project site during surveys predating 2010. Survey protocols followed 

those required for federal listed species that occur within the Santa Rosa Plain Conservation Strategy 

Area (surveys for Sonoma sunshine, Burke’s goldfields, Sebastopol meadowfoam, and many-flowered

navarretia are required to comply with the recommended Guidelines and protocol that are included in the 

Conservation Strategy). The Guidelines require at least three floristic surveys for a minimum of two 

consecutive years to capture these special status species during periods in which they can be identified. 

Reference populations for these species were visited as required. AES staff has completed the required 

floristic surveys for two consecutive years on APNs 066-300-031, 066-300-033, 066-300-028, 066-191-

017, 066-191-018, 066-191-020, and 066-191-022 (see Figure 3). AES staff will conduct the final 

floristic surveys for the second required consecutive year on parcels acquired by the Tribe in 2010 on 

APNs 066-300-023, 066-300-017, 066-191-016, 066-191-019, 066-191-021, 066-050-040 and 066-050-

047. These latter two parcels were surveyed in June and July of 2010 with surveys to be completed by 

July of 2011. Following these surveys, the technical memorandum shall be updated and submitted to the 

USFWS. 

Although no plant species listed by the federal government were found on the project site, two species of 

regional or local concern were found. Harlequin lotus and Lobb’s ranunculus, both CNPS List 4.2, were 

discovered in previous years within wetlands that will be avoided by project design. Thus, there will be 

no impacts on the project site to special status plant species listed by the federal government, or by the 

state of California or local governmental regulations. No special status species are expected in the second 

year of surveys on the seven APNs listed above, which will be the focus of botanical surveys during the 

growing season in 2011.

Important Information About Your Species List 

How We Make Species Lists 

We store information about endangered and threatened species lists by U.S. Geological 

Survey 71⁄2 minute quads. The United States is divided into these quads, which are about the

size of San Francisco. 

The animals on your species list are ones that occur within, or may be affected by projects

within, the quads covered by the list. 

Fish and other aquatic species appear on your list if they are in the same watershed as your 

quad or if water use in your quad might affect them. 

Amphibians will be on the list for a quad or county if pesticides applied in that area may be 

carried to their habitat by air currents.

Birds are shown regardless of whether they are resident or migratory. Relevant birds on the 

county list should be considered regardless of whether they appear on a quad list. 

Sacramento Fish & Wildlife Office Species List Page 6 of 8

http://www.fws.gov/sacramento/es/spp_lists/auto_list.cfm 12/24/2009
Plants

Any plants on your list are ones that have actually been observed in the area covered by the 

list. Plants may exist in an area without ever having been detected there. You can find out 

what's in the surrounding quads through the California Native Plant Society's online

Inventory of Rare and Endangered Plants.

Surveying

Some of the species on your list may not be affected by your project. A trained biologist 

and/or botanist, familiar with the habitat requirements of the species on your list, should 

determine whether they or habitats suitable for them may be affected by your project. We 

recommend that your surveys include any proposed and candidate species on your list. 

See our Protocol and Recovery Permits pages.

For plant surveys, we recommend using the Guidelines for Conducting and Reporting 

Botanical Inventories. The results of your surveys should be published in any environmental 

documents prepared for your project. 

Your Responsibilities Under the Endangered Species Act 

All animals identified as listed above are fully protected under the Endangered Species Act of 

1973, as amended. Section 9 of the Act and its implementing regulations prohibit the take of

a federally listed wildlife species. Take is defined by the Act as "to harass, harm, pursue, 

hunt, shoot, wound, kill, trap, capture, or collect" any such animal. 

Take may include significant habitat modification or degradation where it actually kills or 

injures wildlife by significantly impairing essential behavioral patterns, including breeding, 

feeding, or shelter (50 CFR §17.3). 

Take incidental to an otherwise lawful activity may be authorized by one of two 

procedures:

If a Federal agency is involved with the permitting, funding, or carrying out of a project that may 

result in take, then that agency must engage in a formal consultation with the Service.

During formal consultation, the Federal agency, the applicant and the Service work together to 

avoid or minimize the impact on listed species and their habitat. Such consultation would result 

in a biological opinion by the Service addressing the anticipated effect of the project on listed and

proposed species. The opinion may authorize a limited level of incidental take. 

If no Federal agency is involved with the project, and federally listed species may be taken as 

part of the project, then you, the applicant, should apply for an incidental take permit. The 

Service may issue such a permit if you submit a satisfactory conservation plan for the species 

that would be affected by your project. 

Should your survey determine that federally listed or proposed species occur in the area and are 

likely to be affected by the project, we recommend that you work with this office and the 

California Department of Fish and Game to develop a plan that minimizes the project's direct and 

indirect impacts to listed species and compensates for project-related loss of habitat. You should 

include the plan in any environmental documents you file. 

Critical Habitat 

When a species is listed as endangered or threatened, areas of habitat considered essential 

to its conservation may be designated as critical habitat. These areas may require special 

management considerations or protection. They provide needed space for growth and 

normal behavior; food, water, air, light, other nutritional or physiological requirements;

cover or shelter; and sites for breeding, reproduction, rearing of offspring, germination or 

seed dispersal. 

Sacramento Fish & Wildlife Office Species List Page 7 of 8

http://www.fws.gov/sacramento/es/spp_lists/auto_list.cfm 12/24/2009
Although critical habitat may be designated on private or State lands, activities on these 

lands are not restricted unless there is Federal involvement in the activities or direct harm to 

listed wildlife. 

If any species has proposed or designated critical habitat within a quad, there will be a 

separate line for this on the species list. Boundary descriptions of the critical habitat may be 

found in the Federal Register. The information is also reprinted in the Code of Federal 

Regulations (50 CFR 17.95). See our Map Room page. 

Candidate Species 

We recommend that you address impacts to candidate species. We put plants and animals 

on our candidate list when we have enough scientific information to eventually propose them

for listing as threatened or endangered. By considering these species early in your planning 

process you may be able to avoid the problems that could develop if one of these candidates 

was listed before the end of your project. 

Species of Concern 

The Sacramento Fish & Wildlife Office no longer maintains a list of species of concern. 

However, various other agencies and organizations maintain lists of at-risk species. These 

lists provide essential information for land management planning and conservation efforts. 

More info

Wetlands

If your project will impact wetlands, riparian habitat, or other jurisdictional waters as defined

by section 404 of the Clean Water Act and/or section 10 of the Rivers and Harbors Act, you 

will need to obtain a permit from the U.S. Army Corps of Engineers. Impacts to wetland 

habitats require site specific mitigation and monitoring. For questions regarding wetlands, 

please contact Mark Littlefield of this office at (916) 414-6580. 

Updates

Our database is constantly updated as species are proposed, listed and delisted. If you 

address proposed and candidate species in your planning, this should not be a problem. 

However, we recommend that you get an updated list every 90 days. That would be March 

24, 2010.

SECTION 1.0 

INTRODUCTION 

1.1 PROJECT DESCRIPTION 

The proposed project would be located on Windsor River Road. The proposed project (hereafter 

referred to as the “Windsor Community”) would include 147 residential units, the majority of 

which would be single-family homes. 

The purpose of this study is to evaluate the potential traffic impacts, to recommend any traffic 

mitigation measures that may be required, and to assess the adequacy of the parking proposed. 

This traffic study will also review and make recommendations on the design of the access 

driveways and the internal traffic system proposed for the Windsor Community. This traffic 

study and the trip generation assumptions were prepared based on guidelines set forth by the 

Town of Windsor, Sonoma County and the California Department of Transportation’s (Caltrans) 

Guide to the Preparation of Traffic Impact Studies1

. The location of the Windsor Community 

and the project study area is shown in Figure 1.

1.2 STUDY AREA 

For this analysis ten (10) study intersections were selected for analysis in this report, based on 

their proximity to the site, the Caltrans guidelines, and their potential to be impacted by the 

project. The location of the project study intersections and the study area is shown in Figure 1. 

Intersections #5, 7, 8 and 9 are signalized intersections. The others are controlled by stop signs. 

1. Eastside Road and Windsor River Road 

2. Windsor River Road and Project Entrance (#1)

3. Windsor River Road and Project Entrance (#3) 

4. Windsor River Road and Starr Road

5. Windsor River Road and Windsor Road 

6. Windsor River Road and Bell Road 

7. Windsor River Road and Old Redwood Hwy/Conde Lane 

8. Old Redwood Hwy and the SB Hwy 101 Ramps 

9. Old Redwood Hwy and the NB Hwy 101 Off-Ramp – Lakeside Road 

10. Old Redwood Hwy and Project Entrance (#2) 

All intersections have been analyzed for the AM peak hour (7:30 – 8:30 AM), and the PM 

commute peak hour (5:00-6:00 PM). Intersection turning movement counts were collected by 

Abrams Associates in September 2008, and have been supplemented by traffic counts provided 

by the Town of Windsor (Town). 

It should be noted that based on the standards in the above referenced Caltrans’ Guide to the 

Preparation of Traffic Impact Studies it was determined that additional analysis of roadway 

segments and freeway facilities was not required. Caltrans requirements state that an 

environmental review should include any State Highway facility where more than 100 trips 

would be added or any State Highway facility operating at level of service (LOS) C or LOS D 

where more than 50 trips would be added. Based on the trip generation for the proposed project it 

was determined that the project would add less than 50 trips to any one freeway segment. In 

addition, the intersection LOS analysis did not indicate the project would cause any roadway 

segments to exceed capacity. Based on this information it was determined that further analysis of 

roadway or freeway segments would not yield additional useful information on the project’s 

traffic impacts. 

1.3 PROJECT DESCRIPTION 

The Windsor Community is planned to include 147 residential units. These units would consist 

of approximately 95 single family dwellings (low density), 24 cottage style units (medium

density) and 28 multi-family units (apartments – high density). The project would also include a 

community center, and roundhouse, and a retreat. It is our understanding that these community 

facilities are not expected to be open to the general public and are intended to serve the project 

residents. The proposed site plan is shown on Figure 2.

The project is located just west of the Town on Windsor River Road. Three access driveways on 

Windsor River Road would provide access to the project site. Each of these driveways would be 

controlled by a stop sign on the minor project access approach to Windsor River Road. 

1.4 TRAFFIC ANALYSIS SCENARIOS 

Five study scenarios have been addressed as part of this traffic analysis. These are listed below: 

1) Existing Conditions - This scenario evaluates the level-of-service at the studied 

intersections for the existing conditions based on data provided by the Town of Windsor 

and traffic counts taken in September, 2008. 

2) Background Conditions - This scenario includes the addition of traffic from other 

planned/approved development to the existing traffic volumes. 

3) Background Plus Project Conditions - This scenario includes analyses of the effects 

of traffic from the Proposed Action on the background traffic operations based on data 

provided by the Town of Windsor. 

4) 2030 Cumulative Conditions - This scenario includes the analysis of build-out 

conditions in the area, projected for the Year 2030, plus other development as defined in 

the Sonoma County and Town of Windsor General Plans. 

5) Cumulative Plus Project Conditions - this scenario includes the Cumulative Year 

2030 traffic volumes with the addition of the traffic from the Proposed Action. 

1.5 INTERSECTION ANALYSIS METHODOLOGY 

The level of service measurement is a qualitative description of traffic operating conditions for 

intersections and roadways. Levels of service describe these conditions in terms of such factors 

as speed, travel time, delays, freedom to maneuver, traffic interruptions, comfort, convenience, 

and safety. Levels of service are given letter designations ranging from A to F, which are defined 

in Table 1 and Table 2 below. The LOS measurement that is used to determine the significance 

of any impacts a project might have on traffic and circulation is an intersection’s overall LOS. 

Separate methodologies are used to determine LOS at signalized and unsignalized intersections.

UNSIGNALIZED INTERSECTIONS

For unsignalized intersections the methodology set forth in Chapter 10 of the HCM was used. 

This methodology is based on average total delay (seconds/vehicle). The HCM analysis for 

unsignalized intersections was analyzed using Traffix 7.8. A complete set of detailed LOS 

calculations for each scenario are included in the appendix to this report. As with signalized 

intersections, there are six levels of service for unsignalized intersections, A through F, which 

represent conditions from best to worst, respectively. Table 1 shows the corresponding average 

total delay per vehicle at unsignalized intersections for each LOS category from A to F.

F > 50 Volume>Capacity 

SIGNALIZED INTERSECTIONS

The operating conditions at the signalized study intersections were evaluated using the 

methodologies set forth in the 2000 Highway Capacity Manual (HCM) that is based on average 

total delay (seconds/vehicle). The capacity of each approach is estimated as a function of the 

proportion of traffic on each approach, the number of lanes on each approach, and the proportion 

of turning movements on the opposing and conflicting approaches. With the average total delay 

for each approach the LOS for each and for the entire intersection can then be determined. The 

LOS at each intersection was analyzed using Traffix 7.8 for intersections in the City of Windsor 

and Synchro 6.0.for intersections under Caltrans jurisdiction. A complete set of detailed LOS 

calculations for each scenario are included in the appendix to this report. The LOS definitions for 

signalized intersections are included in Table 2.

SECTION 2.0 

EXECUTIVE SUMMARY 

2.1 PROJECT SITE ACCESS 

The proposed site plan is expected to function well and would not cause any safety or operational 

problems. The main issue to be addressed regarding site access involves the improvements that 

will be required at the intersection of Windsor River Road with the three entrances to the project. 

At these locations the side street (project access) approaches would be controlled with stop signs. 

2.2 INTERSECTION CAPACITY IMPACTS 

Based on our analysis of the trips generated by the Windsor Community we expect that there are 

no off-site traffic improvements that would be required. However, there are two locations where 

the project would add to existing problems and it is expected that the project would need to 

contribute a proportionate amount to the planned improvements. 

The first location is the intersection of Windsor River Road and Bell Road. This is an 

unsignalized intersection that currently has poor operations on the stop controlled side street 

approaches. Although this intersection may never meet the warrants for a traffic signal it is 

expected that the Town may ultimately choose to make safety improvements at this location. We 

are not aware of any plans for this location but it is assumed that the Town may eventually need 

to consider turn restrictions or other physical improvements. The key improvement planned at 

the Old Redwood Hwy/Windsor River Road interchange is at the intersection of Old Redwood 

Highway with the Northbound U.S. 101 off-ramp and Lakewood Drive. At this location there are 

planned improvements that would be expected to require a proportionate share contribution from 

the project. The improvements involve construction of an additional southbound left turn lane, a 

separate right-turn pocket for the westbound approach, and widening of the northbound U.S. 101 

off-ramp to allow for an exclusive left-turn lane, a shared left-through lane, a through lane, and a 

right turn lane for a total of four approach lanes. 

2.3 PARKING IMPACTS 

The Windsor Community would include sufficient off-street parking so that there would be no 

overflow of parked vehicles beyond the project site. Therefore, there are no off-site parking 

impacts anticipated.

3.1 TRANSPORTATION NETWORKS 

ROADWAY SYSTEM

Figure 1 illustrates the roadways in the vicinity of the project site. A brief description of the key 

roadway facilities in the area is provided below. 

Windsor River Road is the major east-west arterial route through the Town of Windsor, and 

extends from Eastside Road to the intersection with Old Redwood Highway and Conde Lane. At 

this point the roadway changes to the Old Redwood Highway just before the interchange with 

Highway 101. Windsor River Road has a speed limit of 30 mph in the downtown area, 35 mph 

west of Windsor Road and 45 mph west of Starr Road. The majority of the other study area 

roadways are local north-south collector roads that connect with Windsor River Road.

Table 3 shows that all signalized study intersections currently operate at LOS D or better during 

both the a.m. and p.m. peak hours with the exception of Intersection #9 which operates at LOS E 

during the PM Peak hour. The Town of Windsor General Plan specifies that LOS E is acceptable 

at this particular intersection. Otherwise LOS D is considered the minimum acceptable level of 

service set forth by the Town of Windsor and Sonoma County. Thus each intersection is assumed 

to operate acceptably according to the applicable Town and County LOS standards. 

INTERSECTION SIGNALIZATION NEEDS

Traffic signals are used to provide for an orderly flow of traffic through an intersection. Many 

times they are needed to provide side street traffic an opportunity to access a major road where 

high volumes and/or high vehicle speeds block crossing or turn movements. They do not, 

however, necessarily increase the capacity of an intersection (i.e., increase the intersection’s 

ability to accommodate additional vehicles) and, in fact, signals often slightly reduce the number 
Abrams Associates

TRAFFIC ENGINEERING, INC.

Abrams Associates 13 Windsor Community

February, 2010 Traffic Impact Study

of total vehicles that can pass through an intersection in a given period of time. Signals can also 

cause an increase in traffic accidents if installed at improper locations. 

There are eleven possible tests (called “warrants”) set forth in the Caltrans Traffic Manual for 

determining whether a traffic signal should be considered for installation. These tests consider 

criteria such as traffic volumes and delay, pedestrian volumes, presence of school children, and 

accident history. Usually, two or more warrants must be met before a signal is installed. If the 

Peak Hour Volume Warrant (Warrant #11) is met at an intersection that is a strong indication that 

a more detailed signal warrant analysis covering all possible warrants is appropriate. The 

requirements for a detailed signal warrant analysis are set forth in Chapter 9 of the Caltrans 

Traffic Manual. 

For these analysis observations of peak hour traffic conditions, a test for peak hour volumes was 

conducted at all unsignalized project study intersections. Our analysis of the existing intersection 

turning movements found that that none of the locations currently meets the peak hour signal 

warrants. In summary, our review indicated that none of the project study intersections would 

meet Caltrans warrants for installation of a traffic signal under existing conditions. 

EXISTING BICYCLE AND PEDESTRIAN SYSTEM

Windsor River Road provides sidewalks and bike lanes in most areas to accommodate pedestrian 

activity. Field observations were performed to determine the general level of bicycle and 

pedestrian activity in the study area. In general, bicycle and pedestrian traffic is relatively light 

and no heavy movements were identified beyond the typical school generated pedestrians. 

TRANSIT SERVICE

Sonoma County Transit provides bus service in the Town of Windsor. Routes 60 and 66 provide 

bus service within the Town. Route 60 provides regional service between Cloverdale and Santa 

Rosa and operates on Windsor River Road and Starr Road on one-hour headways. Route 66 (the 

Windsor Shuttle) provides local service throughout the Town with headways of just over an hour. 

BACKGROUND TRAFFIC VOLUMES

The background a.m. and p.m. peak-hour volumes were developed to include additional traffic 

from approved development in the study area that was provided by the Town. The background 

traffic volumes are presented in Figure 5.

SECTION 4.0 

ENVIRONMENTAL CONSEQUENCES 

4.1 STANDARDS OF SIGNIFICANCE 

Based on the adopted policies of Caltrans, the Town of Windsor, and Sonoma County a traffic 

impact would be considered significant if any of the following conditions, or potential thereof, 

would result from implementation of the Windsor Community Project. 

1. Project traffic would cause an increase in traffic, which is substantial in relation to the 

existing traffic load and capacity of the street system; 

2. Project traffic would cause an intersection, roadway or highway to exceed an established 

level-of-service standard (i.e. a decline in LOS to an unacceptable LOS E or lower); 

3. Project traffic would substantially worsen the LOS at an intersection that operates below 

the applicable LOS standards without the project traffic; 

4. Project traffic would cause an unsignalized intersection to meet the warrants for 

installation of a traffic signal, as set forth by Caltrans; 

5. Project implementation would conflict with related goals, objectives, and policies of the 

Sonoma County General Plan or the Windsor General Plan; 

6. Project implementation would result in inadequate parking capacity resulting in impacts 

to on-street parking; 

7. Project implementation would conflict with transit, pedestrian, and bicycle uses; 

8. The project results in the failure of any street or portion of a street to meet accepted 

safety and design standards or guidelines; 

9. The project would have inadequate emergency access. 

4.2 TRIP GENERATION AND DISTRIBUTION 

The peak-hour trip generation was estimated based on information published in Trip Generation

(Institute of Transportation Engineers, Eighth Edition, 2008). Table 4 summarizes the estimated 

a.m. and p.m. peak-hour trip generation of the proposed project. To be conservative all 

residential units were assumed to generate traffic based on the rates for single-family dwellings. 

The project is estimated to generate a gross total of approximately 110 a.m. peak-hour trips (28 

inbound and 82 outbound) and 148 p.m. peak-hour trips (94 inbound and 54 outbound). None of 

the other community facilities within the project (i.e. the community center, roundhouse, and the 

retreat) are expected to be open to the general public. It is our understanding that these facilities

are primarily intended to serve the project residents and would not generate any substantial 

amount of off-site traffic.

TRIP DISTRIBUTION

The distribution of project traffic was determined based on existing travel patterns and the nature 

of the roadway system serving the proposed project site. Figure 6 shows the proposed trip 

distribution percentages and Figure 7 shows the estimated trip distribution and the number of 

project trips that will be added to intersection movements at each study intersection. 

4.3 BACKGROUND PLUS PROJECT CONDITIONS 

This section of the report describes the conditions where the project traffic is added to the 

background traffic volumes. 

BACKGROUND PLUS PROJECT INTERSECTION LEVELS OF SERVICE

Traffic generated by the proposed Windsor Community project was added to the background a.m. 

and p.m. peak-hour volumes that includes the additional traffic from approved development in the 

study area that was provided by the Town of Windsor. Table 5 summarizes the a.m. and p.m. 

peak-hour LOS at each study intersection under Background and Background plus Proposed 

Action conditions. As seen in this table all signalized intersections are projected to continue to 

operate at LOS D or better with the exception of Intersection #9. The Town of Windsor General 

Plan specifies that LOS E is acceptable at this particular intersection. Thus with the addition of 

project traffic to existing volumes, all of the intersections are projected to operate at acceptable 

LOS according to all applicable standards and the project’s impacts on local traffic operations 

will be less than significant. It should also be noted that an overall review of traffic operations 

and safety was conducted at all of the project driveways including the two minor driveways that 

would be located near the intersection of Windsor River Road with Eastside Road. The review 

indicated the project driveways have adequate sight distance and the project would not result in 

any significant traffic safety or operational problems at any of these locations. In addition it was 

determined that separate left turn pockets would not be warranted at any of the project driveways.

February, 2010 Traffic Impact Study

The Town of Windsor Traffic Impact Fee Program includes planned improvements at two of the 

key study intersections.4

 This includes installation of a traffic signal at the intersection of 

Windsor River Road with Bell Road and improvements at the intersection of Old Redwood 

Highway with the U.S. 101 NB Ramps and Lakewood Drive. The programmed improvements at 

this intersection include construction of an additional southbound left turn lane, an additional 

southbound right-turn lane and restriping the northbound approach to include a shared throughleft lane. It should be noted that Caltrans has also specified the future improvements at this 

intersection could also include a separate right-turn pocket for the westbound approach and 

widening of the northbound U.S. 101 off-ramp to allow for an exclusive left-turn lane, a shared 

left-through lane, a through lane, and a right turn lane (for a total of four approach lanes).5

 

CUMULATIVE CONDITIONS

The cumulative traffic volumes without the Windsor Community project are shown in Figure 8. 

The estimated a.m. and p.m. peak-hour trips under the Proposed Action were added to the 

cumulative condition volumes described previously. This resulted in the estimated traffic 

volumes on the study area roadway system under cumulative plus Windsor Community 

conditions. The results of this process for the a.m. and p.m. peak hours are illustrated in Figure 

9. The level of service at the study intersections was tested using the estimated a.m. and p.m. 

peak-hour traffic volumes for cumulative plus Proposed Action conditions. Table 6 summarizes 

the results of that process. 

ALTERNATIVE TRANSPORTATION CONDITIONS

The project is not expected to result in a substantial increase in bicycling activity or to adversely 

impact the existing or planned bicycle system in the vicinity of the project site under cumulative 

plus Proposed Action conditions. Thus no significant adverse impacts on bicycle conditions in 

the area are projected. 

The project is also not expected to adversely impact the existing or planned pedestrian system in 

the vicinity of the project site under cumulative plus Proposed Action conditions. No significant 

adverse impacts on pedestrians are, therefore, anticipated in connection with the proposed project. 

It should also be noted that implementation of the proposed project is not expected to generate a 

substantial amount of additional transit riders under cumulative plus Proposed Action conditions. 

Therefore, no adverse transit impacts are anticipated.

4.5 ALTERNATIVES ANALYSIS 

This section of the report describes the alternatives that could potentially replace the proposed 

project, as presented in the preliminary site schemes 2 and 3 (February 26, 2008). The analysis 

consisted of the evaluation of two different project alternatives that include varying sizes of the 

proposed project. The purpose of the analysis is to identify the potential impacts due to the 

alternative land uses and compare them with the impacts of the proposed project presented in the 

traffic study. The following project alternatives were analyzed: 

Preliminary Site Scheme 2 – This alternative has the same number of residential units as the 

proposed project (147 units) but would also include an on-site wastewater treatment plant. 

Preliminary Site Scheme 3 – This alternative has a reduced number of residential units (55 units) 

and also an on-site wastewater treatment plant with its own water storage basin. 

The trip generation for each of the alternatives is shown in Table 7. As shown in the table the 

project alternatives would each generate either the same or substantially less traffic than the 

proposed project and it was assumed that the distribution of project trips would be the same as the 

proposed project. An analysis of the potential traffic impacts for the alternatives indicates that the 

impacts and proposed mitigations would be identical to the proposed project for each of the 

alternatives. 

This is due to the fact that the two mitigations measures proposed involve contributions to 

transportation improvements that would be required regardless of whether or not the proposed 

project or either of the alternatives are implemented. The only difference that would be expected 

under the two alternatives would be with Scheme 3 which would have a reduced proportionate 

contribution to the mitigations due to the reduced traffic from that alternative.

SECTION 5.0 

SUMMARY OF IMPACTS AND MITIGATION MEASURES 

Based on our analysis of the trips generated by the Windsor Community it has been concluded 

that there are no off-site traffic improvements that would be required. However, there are two 

locations where the project would add to existing traffic problems and it is expected that the 

project would need to contribute a proportionate amount to the planned improvements. 

5.1 BACKGROUND PLUS PROJECT IMPACTS AND 

MITIGATION MEASURES 

All intersections would continue to operate within the LOS standards established by Sonoma 

County, the Town of Windsor, and Caltrans under background plus project conditions. No 

mitigations would be required under this scenario. 

5.2 2030 PLUS PROJECT IMPACTS AND MITIGATION 

MEASURES 

This section of the report describes the mitigation measures for the cumulative plus project traffic 

conditions in the Year 2030. With the implementation of the proposed mitigations all 

intersections would operate within the established LOS standards and all impacts would be 

reduced to a less-than-significant level. 

Impact 1.1 The Proposed Project would contribute to the unacceptable operations at the 

intersection of Windsor River Road with Bell Road. This would be considered a significant 

impact. 

The one unsignalized location where a problem is forecast under the cumulative plus project 

scenario is at the intersection of Windsor River Road and Bell Road. This intersection will 

eventually have poor operations on the stop controlled side street approaches. The timing for this 

intersection meeting the warrants for a traffic signal cannot be determined at this time but the 

Town has incorporated plans for a traffic signal into their Traffic Impact Fee Program. 

Mitigation Measure 1.1 The project applicant shall pay a proportionate share for necessary 

intersection improvements at this location including, but not limited to, installation of a traffic 

signal if and when the Town determines a signal is warranted. Please note that with the 

implementation of this proposed mitigation this intersection would operate within the LOS

TRAFFIC ENGINEERING, INC.

Abrams Associates 26 Windsor Community

February, 2010 Traffic Impact Study

standards established by Sonoma County, the Town, and Caltrans and all impacts would be 

reduced to a less-than-significant level. 

Impact 1.2 The Proposed Project would increase traffic at the intersection of Old Redwood 

Highway with the Northbound U.S.101 Off-Ramp and Lakewood Drive which is forecast to 

have deficient operations without planned improvements. This would be considered a 

potentially significant impact. 

A key improvement for future circulation is planned on the Old Redwood Highway at the 

intersection with the Northbound U.S. 101 Off-Ramp and Lakewood Drive. At this location there 

are planned improvements that would be expected to require a proportionate share contribution 

from the project. The improvements needed to address the expected deficiencies are currently 

planned and the Town has incorporated the plans for these improvements into their Traffic Impact 

Fee Program. Therefore, this would be considered a potentially significant impact. 

Mitigation Measure 1.2 The required improvements at this intersection involve construction of 

an additional southbound left turn lane, an additional southbound right-turn lane and restriping 

the northbound approach to include a shared through-left lane. The LOS analysis using Synchro 

indicates that the intersection would have acceptable operations and meet the LOS Standards 

(LOS E) with the implementation of these improvements. In addition, the Town’s 

Redevelopment Plan EIR6

 specifies that this intersection would operate at LOS D based on the 

City’s Traffix analysis of future buildout conditions. 

The proposed project’s required contribution will help ensure timely completion of this 

improvement. It is assumed that the project’s equitable share of any planned improvements at 

this intersection would be calculated based on the methodology set forth in Appendix “B” of the 

previously referenced Caltrans “Guide for the Preparation of Traffic Impact Studies”. It is also 

assumed this will be determined in consultation with Sonoma County, the Town of Windsor and 

the applicant. Implementation of this mitigation measure would reduce this impact to a less than 

significant level.

SECTION 1.0

INTRODUCTION

1.1 PURPOSE 

Analytical Environmental Services (AES) has prepared this Environmental Site Assessment 

(ESA) in conformance with the Bureau of Indian Affairs (BIA) guidelines (602 DM Chapter 2) 

and the American Society for Testing and Materials (ASTM) Standard Practice E 1527-05, which 

specifies the appropriate inquiry requirement for the innocent landowner defense under 

CERCLA. This ESA encompasses one legal parcel with a total area of approximately 50.46-

acres located in the County of Sonoma, California (Figure 1). The purpose of this ESA is to 

identify Recognized Environmental Conditions (RECs) that may affect future uses of the Subject 

Property. 

This ESA covers the Subject Property, adjacent areas, and surrounding known sources of 

contamination, up to 2.0 miles from a point roughly equivalent to the middle of the Subject 

Property. Site reconnaissance inspections of the Subject Property and adjacent properties were 

performed and relevant database listings of hazardous sites, waste generators, and underground 

storage tanks were reviewed (EDR, 2007). AES also reviewed historical aerial photographs for 

the Subject Property. Years available for review were 1952, 1965, 1974, 1982, 1993, and 1998. 

1.2 RECOGNIZED ENVIRONMENTAL CONDITIONS 

The term Recognized Environmental Condition (REC) refers to the presence or likely presence of 

any hazardous substances or petroleum products on a property under conditions that indicate an 

existing release, a past release, or a material threat of release of any hazardous substances or 

petroleum products into structures on the property or into the ground, groundwater, or surface 

water of the property. The term includes hazardous substances or petroleum products even under 

conditions in compliance with laws. The term is not intended to include de minimis conditions

that generally do not present a material risk of harm to public health or the environment and that 

generally would not be the subject of an enforcement action if brought to the attention of 

appropriate governmental agencies. Additionally, the term historical REC refers to an 

environmental condition associated with the Subject Property, including a past release of any 

hazardous substance or petroleum product, which in the past would have been considered a REC,

however such condition has since been remediated. Historical RECs will therefore be included in 

this Phase I ESA (ASTM 2005). 

1.3 LIMITATIONS AND EXCEPTIONS 

No ESA can completely eliminate uncertainty regarding the potential for RECs in connection 

with a property. Conformance of this assessment with ASTM Standard Practice E 1527-05 will 

reduce, but not eliminate, uncertainty regarding the potential for RECs in connection with the 

Subject Property. While AES has made every effort to discover and interpret available historical 

and current information on the property within the time available, the possibility for undiscovered 

contamination to be present remains. AES’s report is a best-effort collection and interpretation of 

available information consistent with industry standards for the completion of Phase I ESAs. 

This ESA is based on a site reconnaissance of the Subject Property, searches of government 

hazardous materials databases, and interviews with individuals familiar with the historical uses of 

the Subject Property. Physical testing of soil or groundwater was not within the scope of this 

assessment. Asbestos containing building materials (ACM) and lead-based paint surveys were 

not included. Information was obtained for this ESA to comply with ASTM guidelines.

1.4 METHODOLOGY 

A variety of data sources were consulted in completing this Phase I ESA. The following subsections describe the methods used and the data sources consulted to accomplish each task.

1.4.1 HISTORICAL REVIEW 

Previous land uses and history of the Subject Property were researched in an effort to identify 

RECs at or near the Subject Property. Historical aerial photographs (Appendix A) and

topographic maps (Appendix B) from different decades were examined for the presence of 

aboveground storage tanks, industrial buildings, gas station canopies and/or pump islands, as well 

as other indications of bulk hazardous material storage within the study area. Sanborn Fire 

Insurance Maps document historical property use through abbreviations and map symbols that 

identify commercial, industrial, residential and other land uses (Appendix C).

1.4.2 DATABASE SEARCHES 

Database searches were made for records of known storage tank sites and known sites of 

hazardous materials generation, storage or contamination. Available information from federal, 

state, and local agency lists of: (a) known or potential hazardous waste sites and landfills; (b) sites 

currently under investigation for environmental violations; (c) sites which manufacture, generate, 

use, store, and/or dispose of hazardous materials or hazardous wastes; (d) sites which have 
1.0 Introduction 

 

Analytical Environmental Services 1-4 Lytton Windsor Property 

May 2007 Phase I Environmental Site Assessment

underground storage tanks (USTs); and (e) sites with recorded violations of regulations 

concerning USTs and hazardous materials/hazardous wastes. The database search is intended to 

identify facilities that may have the potential to impact surface and subsurface conditions on the 

Subject Property. A full listing of sites within the vicinity of the Subject Property is provided in 

Appendix D.

1.4.3 SITE RECONNIASSANCE 

Pete Connelly from AES conducted a reconnaissance inspection of the Subject Property and 

adjacent properties on April 24, 2007. The purpose of the site reconnaissance is to examine for 

obvious physical indications of improper hazardous substance or petrochemical disposal such as 

stained soil or asphalt, stressed vegetation, sumps, partially buried drums, bulk underground fuel 

storage tanks, and other obvious signs of hazardous materials involvement. In addition, adjacent 

properties were visually inspected to the extent possible without trespassing on private property 

to determine if current land uses would affect the planned uses of Subject Property. 

1.5 DEVIATIONS AND DATA GAPS 

ASTM Standard 1527-05 requires any significant data gaps, deviations and deletions from the 

ASTM Standard to be identified and commented on in the Phase I. A significant data gap would 

be one that affected the ability to identify a REC on the Subject Property or adjacent properties. 

Due to the rural location of the Subject Property, Sanborn Fire Insurance maps and City 

Directories were not available for the Subject Property. Because there is no historical data or 

physical indications that the property has ever been developed or occupied by a business that 

would have produced hazardous materials, the lack of Sanborn Fire Insurance maps and City 

Directories is not considered a significant data gap for this Phase I ESA.

1.6 CREDENTIALS 

Pete Connelly prepared this report under the professional supervision of David Zweig, P.E., who 

qualifies as an environmental professional (EP) as defined in the ASTM Standard 1527-05. Pete 

Connelly and David Zweigs’ signatures appear in Section 6.0 of this Phase I, and their resumes 

are included as Appendix F.

1.7 CONCLUSIONS AND RECOMMENDATIONS 

Based on information gathered while conducting this Phase I ESA, AES observed the following 

environmental conditions: 
1.0 Introduction 

 

Analytical Environmental Services 1-5 Lytton Windsor Property 

May 2007 Phase I Environmental Site Assessment

x The approximately 55.46-acre Subject Property is currently undeveloped. No historical 

records were found that document buildings being present on the Subject Property. 

x Several items of non-hazardous debris were noted on the Subject Property. These items 

include a dishwasher, stove, two camper shells, carpet, wood debris, and an empty 55-

gallon drum. The debris located on the Subject Property appeared to be primarily 

household type non-hazardous debris. The debris is concentrated in the southern central 

portions of the Subject Property. 

x The remains of an automobile were present on the Subject Property. The automobile is 

located off the dirt road in the central portion of the Subject Property. 

x Two small excavated pits were observed on the Subject Property. It appears the pits were 

used for watering livestock. 

AES did not identify any RECs associated with the Subject Property or adjacent properties. 

Based on the findings and conclusions of this Phase I ESA, AES has the following 

recommendations. 

x All household debris should be removed from the Subject Property and disposed at a 

licensed disposal facility. 

x The abandoned automobile should be removed from the site by a licensed automobile 

recycler or contractor of a licensed recycler.

SECTION 2.0 

SITE DESCRIPTION 

2.1 LOCATION AND LEGAL DESCRIPTION

The address of the 50.46-acre Subject Property is 1640 Windsor River Road, Windsor, California 

(Figures 2 and 3). The Sonoma County assessors’ parcel number (APN) for the Subject Property 

is 066-300-031. 

2.2 SITE AND VICINITY CHARACTERISTICS 

The Subject Property is located in the southern portion of the Russian River Valley, 

approximately 1 mile east of the Russian River and 0.7 mile northwest of Windsor Creek. The 

Subject Property is comprised of dense to light oak woodland and natural grasses dispersed 

throughout gently rolling hills with slopes ranging from 5 to 20% and elevations ranging 140 to 

200 feet above mean sea level (msl). No buildings exist on the Subject Property. 

2.3 HYDROLOGY

There are no storm drains, vegetated swales, or any other storm water improvements on the 

Subject Property. Storm water on the site follows the natural topography, flowing downhill into 

several natural drainages that are present on the Subject Property. 

2.4 GEOLOGY AND SOIL

The Subject Property is located on the formation known as the Huichica and Glen Ellen 

Formation. Soils on the site generally consist of several types including Felta and Spreckles loan 

and a small area of Arbuckle gravely sandy loam. The Felta and Sprekles series formed from 

volcanic tufts mixed with uplifted river sediment and metamorphic 

2.5 CURRENT USES OF THE SUBJECT PROPERTY

Pete Connelly from AES performed a site reconnaissance survey of the Subject Property on April 

24, 2007. The Subject Property is located in Windsor California. Current use of the Subject 

Property is for pasture, although no livestock were observed during the site visit. There is

evidence of an abandoned homeless camp on the site including the remains of a camper shell. 

The homeless camp appeared abandoned. There were several appliances, wood debris, remains 

of a second camper, an abandoned automobile, an empty 55-gallon drum, and other nonhazardous debris on the Subject Property. Site photos showing conditions of the Subject Property 

during the site visit are shown in Figures 4 and 5.

2.6 HISTORICAL USES OF THE SUBJECT PROPERTY

Sonoma County tax assessors’ office has no records of building permits being issued for the 

Subject Property (Sonoma County, 2007). A review of historical aerials shows no changes in 

land use since 1952. A previous Phase I documented the property as being used for pasture, 

although no livestock were observed on the property. There is no historical information that 

documents building being present on the Subject Property. AES interviewed the neighboring 

property owner (Coston, 2007) during the site visit. Trespassing has occurred on the Subject 

Property in the past. Ms. Coston and the neighboring property owners negotiated with the current 

owners of the Subject Property to install a locked gate along the eastern property boundary in 

order to secure the Subject Property and to keep people from trespassing on the Subject Property. 

2.7 AERIAL PHOTOGRAPHS 

Historical aerial photographs (Appendix A) and topographic maps (Appendix B) were reviewed 

for the Subject Property. Years available for review were 1952 (1”=555’), 1965 (1”=333’), 1974 

(1”=541’), 1982 (1”=690’), 1993 (1”=666’), 1998 (1”=666’), and 2007. The 2007 aerial 

photograph is presented as figure 3. Aerial photographs were of varying scale and clarity. 

Historical aerial images offer detailed review of previous land uses on the Subject Property and 

adjacent properties. 

1952 through 1974 

No structures are visible on the Subject Property in the 1952 through 1974 aerial photographs. 

Windsor River Road appears in the 1952 aerial photo to the north of the Subject Property. 

Adjacent properties are either undeveloped or rural in nature. 

1982 through 2003 

Similar to the previous photos, the Subject Property is undeveloped. Land uses have not changed 

on the Subject Property or adjacent properties in these photos. Adjacent properties are rural 

residential and undeveloped with the exception of residential developments on the north side of 

Windsor River Road.

SECTION 3.0 

SITE RECONNAISSANCE AND INTERVIEWS 

3.1 OBJECTIVE

The objective of the site reconnaissance is to identify current or historic hazardous materials 

involvement on the Subject Property or in the vicinity of the Subject Property. Hazardous 

materials involvement, or signature environmental conditions include the presence or likely 

presence of any hazardous materials or petroleum products that indicate an existing release, past 

release, or a threat of release into any structure on the property, soil, or groundwater. Signs of 

possible hazardous materials involvement would include any indications of underground storage 

tanks existing on the Subject Property, stained soils and/or unusual odors originating from the 

Subject Property, indications of an excavation or removal of soils, including patched asphalt and 

large debris piles, and other obvious signs of hazardous materials involvement. 

Interviews included contacting individuals familiar with the Subject Property and adjacent 

properties that are knowledgeable of historic and existing conditions relative to hazardous 

materials. 

3.2 SITE RECONNAISSANCE FINDINGS 

Pete Connelly from AES conducted a site reconnaissance of the Subject Property on April 24, 

2007. Adjacent properties were observed to the extent possible without trespassing. Figures 4 

and 5 show site conditions at the time of the site visit. Notable features and environmental 

conditions are summarized below: 

x The Subject Property is surrounded by a barbed wire fence. Access to the Subject 

Property is through two gates. The first gate is located off Windsor River Road through a 

dirt road on the northern border of the Subject Property. The second gate is located off a 

private road along the eastern border of the Subject Property (Photos 1 and 2).

x The Subject Property is comprised of 50.46-acres of undisturbed natural oak woodland 

with a few small areas of open grasses (Photos 3 through 5). Two small excavations 

were noted on the Subject Property (Photo 6).
3.0 Site Reconnaissance and Interviews 

Analytical Environmental Services 3-2 Lytton Windsor Property 

May 2007 Phase I Environmental Site Assessment

x Non-hazardous debris is present in several locations on the Subject Property, mostly in 

the central portions next to dirt roads that originate on the eastern property boundary. 

Items that were noted were appliances, an automobile, two camper shells, an empty 55-

gallon drum, and several piles of wood debris (Photos 7 through 10). 

ADJACENT PROPERTIES 

AES performed a survey of adjacent properties to the extent possible without trespassing. The 

purpose is to identify adjacent businesses and determine if current land uses would affect the 

planned use of the Subject Property. 

x North: Two residential dwellings and Windsor River Road. Beyond Windsor River 

Road are rural residential and agricultural properties. 

x South: Vineyards, undeveloped, agricultural, and rural residential. 

x East: Agricultural, and rural residential.

x West: Undeveloped and rural residential.

3.3 INTERVIEW AND QUESTIONNAIRES 

A standard property owner and user questionnaire was sent to the current property owner on April 

20, 2007. The questionnaires are included as Appendix E. AES also interviewed the property 

owner that occupies one of the residences to the north of the Subject Property.

RECORDS REVIEW 

4.1 DATABASE SEARCH

Database searches were conducted for records of known storage tank sites and known sites of 

hazardous materials generation, storage, and/or contamination. Databases were searched for sites 

and listings up to two miles from a point roughly equivalent to the center of the Subject Property.

The environmental database review was accomplished by using the services of a computerized 

search firm Environmental Data Resources, Inc. (EDR). EDR uses a geographical information 

system to plot locations of past or previous hazardous materials involvement. AES reviewed the 

EDR report to determine if the Subject Property and adjacent sites are listed on regulatory agency 

databases. The purpose is to determine if adjacent sites will impact surface and/or subsurface 

conditions on the Subject Property. Included in the EDR database report was a list of “unmapped 

sites”. AES reviewed the list of unmapped sites for the properties that may be located within the 

search radius specified for each governmental database. These sites do not appear to be located 

within the applicable search radius of the Subject Property. The complete list of reviewed 

databases is provided in the EDR report, included in Appendix D and is summarized in Table 1.

Information on past and/or current hazardous materials involvement involving adjacent properties 

is summarized in Section 4.2.2. 

4.2 HAZARDOUS MATERIALS INVOLVEMENT 

A regulatory agency database report was performed to identify locations of past and/or current 

hazardous materials involvement. Regulatory agency databases were searched for records of 

known storage tank sites and known sites of hazardous materials generation, storage, or 

contamination, or where violations pertaining to storage and/or use of hazardous materials have 

occurred. Databases were searched for sites and listings up to one mile from a point roughly 

equivalent to the center of Subject Property. Although a site may be listed within the database 

report, this does not mean the site is currently contaminated or will impact the environmental 

quality of the Subject Property. It should be noted that the database search is only as accurate as 

the data entered into the government agency maintained databases and the date on which those 

databases were last updated. Installation of underground storage tanks or hazardous material 

releases, if not reported to the appropriate agency, would not be listed on any of the databases 

searched.

Analytical Environmental Services 4-3 Lytton Windsor Property 

May 2007 Phase I Environmental Site Assessment

4.2.1 SUBJECT PROPERTY

The Subject Property was not listed on any of the regulatory agency databases that were searched 

by EDR. 

4.2.2 ADJACENT PROPERTIES

Several sites were listed in the vicinity of the Subject Property. None of the sites pose an 

environmental threat to the proposed use of the Subject Property. The following paragraphs 

summarize the sites that are located within 0.50 miles of the Subject Property. 

The Windsor Prisoner of War Camp (POW) is located approximately 0.35 miles west southwest 

of the Subject Property. No address is given for the former POW site. The site was used by the 

Department of Agriculture as a camp for migrant farm workers and later as a POW labor camp. 

There are no records of hazardous material being released on the site. No potential hazards 

related to Department of Defense activity have been located at this site. 

The Eff Waugh site is located approximately 0.44 miles west southwest of the Subject Property 

on Eastside Road, Healdsburg. The site is listed on the LUST and Cortese databases. Gasoline 

was released into the groundwater. Preliminary site assessments are underway and affected soils 

are being excavated and removed to an approved site. It is likely that the groundwater flow 

direction under the site is to the west, towards the Russian River, which is away from the Subject 

Property. It is therefore not likely that the Eff Waugh site would affect the Subject Property. 

A private residence located at 9228 Eastside Road is listed on the SWEEPS UST database. No 

additional information is given in the EDR report for this site. 

The Syar Industries, Inc site is located approximately 0.47 miles west southwest of the Subject 

Property at 9000 Eastside Road. The site is listed on the LUST database as a closed case. The 

site is also listed on the Hist UST and SWEEPS UST databases and the location of one 10,000-

gallon diesel UST.

The Calplan Vineyards site is located approximately 0.50 miles southwest of the Subject Property 

at 8500 Eastside Road. The site is listed on the LUST, Cortese and SWEEPS UST databases. 

The LUST database identifies the site as a closed case. The SWEEPS UST database identifies 

the site as the previous location of two USTs. 

The remaining sites are located beyond 0.50 miles from the Subject Property. None of the 

remaining sites are likely to pose a risk to the environmental quality of the Subject Property. 
SECTION 5.0

FINDINGS AND CONCLUSIONS
Analytical Environmental Services 5-1 Lytton Windsor Property 

May 2007 Phase I Environmental Site Assessment

SECTION 5.0 

FINDINGS AND CONCLUSIONS 

This Phase I Environmental Site Assessment was performed in conformance with the scope and 

limitations of ASTM Standard Practice E1527-05 and BIA guidelines (602 DM Chapter 2). 

Based on information gathered while conducting this Phase I ESA, AES observed the following 

environmental conditions: 

x The approximately 50.46-acre Subject Property is currently undeveloped. No historical 

records were found that document buildings being present on the Subject Property. 

x Several items of non-hazardous debris were noted on the Subject Property. These items 

include a dishwasher, stove, two camper shells, carpet, wood debris, and an empty 55-

gallon drum. The debris located on the Subject Property appeared to be primarily 

household type non-hazardous debris. The debris is concentrated in the southern central 

portions of the Subject Property. 

x The remnants of an automobile were present on the Subject Property. The automobile is 

located off the dirt road in the central portion of the Subject Property. 

x Two small excavated pits were observed on the Subject Property. It appears the pits were 

used for watering livestock. 

AES did not identify RECs associated with the Subject Property or adjacent properties. Based on 

the findings and conclusions of this Phase I ESA, AES has the following recommendations. 

x All debris should be removed from the Subject Property and disposed at a licensed 

disposal facility. 

x The abandoned automobile should be removed from the site by a licensed automobile 

recycler or contractor of a licensed recycler.

there may be reasons to investigate further. The database includes the following site types: Federal

Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State

Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information

that was available in CalSites, and provides additional site information, including, but not limited to,

identification of formerly-contaminated properties that have been released for reuse, properties where

environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk

characterization information that is used to assess potential impacts to public health and the environment at

contaminated sites.

 A review of the ENVIROSTOR list, as provided by EDR, and dated 02/27/2007 has revealed that there are

 2 ENVIROSTOR sites within approximately 1.25 miles of the target property.

CERCLIS-NFRAP: CERCLIS No Further Remedial Action Planned

Archived sites are sites that have been removed and archived from the inventory of CERCLIS sites. Archived status

indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined

no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates

this decision was not appropriate or other considerations require a recommendation for listing at a later time.

This decision does not necessarily mean that there is no hazard associated with a given site; it only means that,

based upon available information, the location is not judged to be a potential NPL site.

GOVERNMENT RECORDS SEARCHED / DATA CURRENCY TRACKING
RCRAInfo is EPA’s comprehensive information system, providing access to data supporting the Resource Conservation

and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. RCRAInfo replaces

the data recording and reporting abilities of the Resource Conservation and Recovery Information System (RCRIS).

The database includes selective information on sites which generate, transport, store, treat and/or dispose of

hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Conditionally exempt small

quantity generators (CESQGs) generate less than 100 kg of hazardous waste, or less than 1 kg of acutely hazardous

waste per month. Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per

month. Large quantity generators (LQGs) generate over 1,000 kilograms (kg) of hazardous waste, or over 1 kg

of acutely hazardous waste per month. Transporters are individuals or entities that move hazardous waste from

the generator off-site to a facility that can recycle, treat, store, or dispose of the waste. TSDFs treat, store,

or dispose of the waste.

US BROWNFIELDS: A Listing of Brownfields Sites

Included in the listing are brownfields properties addresses by Cooperative Agreement Recipients and brownfields

properties addressed by Targeted Brownfields Assessments. Targeted Brownfields Assessments-EPA’s Targeted Brownfields

Assessments (TBA) program is designed to help states, tribes, and municipalities--especially those without EPA

Brownfields Assessment Demonstration Pilots--minimize the uncertainties of contamination often associated with

brownfields. Under the TBA program, EPA provides funding and/or technical assistance for environmental assessments

at brownfields sites throughout the country. Targeted Brownfields Assessments supplement and work with other efforts

under EPA’s Brownfields Initiative to promote cleanup and redevelopment of brownfields. Cooperative Agreement

Recipients-States, political subdivisions, territories, and Indian tribes become Brownfields Cleanup Revolving

Loan Fund (BCRLF) cooperative agreement recipients when they enter into BCRLF cooperative agreements with the

U.S. EPA. EPA selects BCRLF cooperative agreement recipients based on a proposal and application process. BCRLF

cooperative agreement recipients must use EPA funds provided through BCRLF cooperative agreement for specified

brownfields-related cleanup activities.

UMTRA: Uranium Mill Tailings Sites

Uranium ore was mined by private companies for federal government use in national defense programs. When the mills

shut down, large piles of the sand-like material (mill tailings) remain after uranium has been extracted from

the ore. Levels of human exposure to radioactive materials from the piles are low; however, in some cases tailings

were used as construction materials before the potential health hazards of the tailings were recognized.

Site Mitigation and Brownfields Reuse Program Facility Sites with Deed Restrictions & Hazardous Waste Management

Program Facility Sites with Deed / Land Use Restriction. The DTSC Site Mitigation and Brownfields Reuse Program

(SMBRP) list includes sites cleaned up under the program’s oversight and generally does not include current

or former hazardous waste facilities that required a hazardous waste facility permit. The list represents deed

restrictions that are active. Some sites have multiple deed restrictions. The DTSC Hazardous Waste Management

Program (HWMP) has developed a list of current or former hazardous waste facilities that have a recorded land

use restriction at the local county recorder’s office. The land use restrictions on this list were required by

the DTSC HWMP as a result of the presence of hazardous substances that remain on site after the facility (or

part of the facility) has been closed or cleaned up. The types of land use restriction include deed notice, deed

restriction, or a land use restriction that binds current and future owners.

EDR PROPRIETARY RECORDS

Manufactured Gas Plants: EDR Proprietary Manufactured Gas Plants

The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)

compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s

to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture

of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,

such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds

are potentially hazardous to human health and the environment. The byproduct from this process was frequently

disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil

and groundwater contamination.

SURROUNDING SITES: SEARCH RESULTS

Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on

a relative (not an absolute) basis. Relative elevation information between sites of close proximity

should be field verified. Sites with an elevation equal to or higher than the target property have been

differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed

data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

Archived sites are sites that have been removed and archived from the inventory of CERCLIS sites. Archived status

indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined

no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates

this decision was not appropriate or other considerations require a recommendation for listing at a later time.

This decision does not necessarily mean that there is no hazard associated with a given site; it only means that,

based upon available information, the location is not judged to be a potential NPL site.

RCRAInfo is EPA’s comprehensive information system, providing access to data supporting the Resource Conservation

and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. RCRAInfo replaces

the data recording and reporting abilities of the Resource Conservation and Recovery Information System (RCRIS).

The database includes selective information on sites which generate, transport, store, treat and/or dispose of

hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Conditionally exempt small

quantity generators (CESQGs) generate less than 100 kg of hazardous waste, or less than 1 kg of acutely hazardous

waste per month. Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per

month. Large quantity generators (LQGs) generate over 1,000 kilograms (kg) of hazardous waste, or over 1 kg

of acutely hazardous waste per month. Transporters are individuals or entities that move hazardous waste from

the generator off-site to a facility that can recycle, treat, store, or dispose of the waste. TSDFs treat, store,

or dispose of the waste.

Assessments (TBA) program is designed to help states, tribes, and municipalities--especially those without EPA

Brownfields Assessment Demonstration Pilots--minimize the uncertainties of contamination often associated with

brownfields. Under the TBA program, EPA provides funding and/or technical assistance for environmental assessments

at brownfields sites throughout the country. Targeted Brownfields Assessments supplement and work with other efforts

under EPA’s Brownfields Initiative to promote cleanup and redevelopment of brownfields. Cooperative Agreement

Recipients-States, political subdivisions, territories, and Indian tribes become Brownfields Cleanup Revolving

Loan Fund (BCRLF) cooperative agreement recipients when they enter into BCRLF cooperative agreements with the

U.S. EPA. EPA selects BCRLF cooperative agreement recipients based on a proposal and application process. BCRLF

cooperative agreement recipients must use EPA funds provided through BCRLF cooperative agreement for specified

brownfields-related cleanup activities.

UMTRA: Uranium Mill Tailings Sites

Uranium ore was mined by private companies for federal government use in national defense programs. When the mills

shut down, large piles of the sand-like material (mill tailings) remain after uranium has been extracted from

the ore. Levels of human exposure to radioactive materials from the piles are low; however, in some cases tailings

were used as construction materials before the potential health hazards of the tailings were recognized.

HIST FTTS: FIFRA/TSCA Tracking System Administrative Case Listing

A complete administrative case listing from the FIFRA/TSCA Tracking System (FTTS) for all ten EPA regions. The

information was obtained from the National Compliance Database (NCDB). NCDB supports the implementation of FIFRA

(Federal Insecticide, Fungicide, and Rodenticide Act) and TSCA (Toxic Substances Control Act). Some EPA regions

are now closing out records. Because of that, and the fact that some EPA regions are not providing EPA Headquarters

with updated records, it was decided to create a HIST FTTS database. It included records that may not be included

in the newer FTTS database updates. This database is no longer updated.

Program Facility Sites with Deed / Land Use Restriction. The DTSC Site Mitigation and Brownfields Reuse Program

(SMBRP) list includes sites cleaned up under the program’s oversight and generally does not include current

or former hazardous waste facilities that required a hazardous waste facility permit. The list represents deed

restrictions that are active. Some sites have multiple deed restrictions. The DTSC Hazardous Waste Management

Program (HWMP) has developed a list of current or former hazardous waste facilities that have a recorded land

use restriction at the local county recorder’s office. The land use restrictions on this list were required by

the DTSC HWMP as a result of the presence of hazardous substances that remain on site after the facility (or

part of the facility) has been closed or cleaned up. The types of land use restriction include deed notice, deed

restriction, or a land use restriction that binds current and future owners.

EDR PROPRIETARY RECORDS

Manufactured Gas Plants: EDR Proprietary Manufactured Gas Plants

The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)

compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s

to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture

of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,

such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds

are potentially hazardous to human health and the environment. The byproduct from this process was frequently

disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil

and groundwater contamination.

SECTION 1.0

INTRODUCTION

1.1 PURPOSE 

This Phase I Environmental Site Assessment (ESA) has been prepared for the Lytton Rancheria 

by Analytical Environmental Services (AES) in conformance with the American Society for 

Testing and Materials (ASTM) Standard Practice E 1527-05 and the Bureau of Indian Affairs 

(BIA) guidelines. As such, this practice is intended to permit a user to satisfy one of the 

requirements to qualify for the innocent landowner, contiguous property owner, or bona fide 

prospective purchaser limitations on CERCLA liability (“landowner liability protection” or

“LLPs”). That is, the practice that constitutes “all appropriate inquiry into the previous 

ownership and uses of the property consistent with good commercial or customary practice” as 

defined at 42 U.S.C §9601 (35) (B). This Phase I ESA encompasses three legal parcels with a 

total acreage of 21.23 located in the County of Sonoma, California (Figure 1). As such, the use 

of the term “Subject Property” refers to the entire 21.23-acre property unless otherwise stated. 

The purpose of this assessment is to identify Recognized Environmental Conditions (RECs) that 

may affect future uses of the Subject Property. 

This assessment covers the Subject Property, adjacent areas, and surrounding known sources of 

contamination, up to 1.0 miles from a point roughly equivalent to the middle of the Subject 

Property. Site reconnaissance inspections of the Subject Property and adjacent properties were 

performed and relevant database listings of hazardous materials sites, hazardous waste generators, 

and underground storage tanks were reviewed (EDR, 2008). AES also reviewed historical aerial 

photographs for the Subject Property. Years available for review were 1952, 1965, 1974, 1982, 

1993, 1998, and 2005. 

1.2 RECOGNIZED ENVIRONMENTAL CONDITIONS 

The term Recognized Environmental Condition (REC) refers to the presence or likely presence of 

any hazardous substances or petroleum products on a property under conditions that indicate an 

existing release, a past release, or a material threat of release of any hazardous substances or 

petroleum products into structures on the property or into the ground, groundwater, or surface 

water of the property. The term includes hazardous substances or petroleum products even under 
Lytton 22-Acre Phase I ESA / 207513

conditions in compliance with laws. The term is not intended to include de minimis conditions

that generally do not present a material risk of harm to public health or the environment and that 

generally would not be the subject of an enforcement action if brought to the attention of 

appropriate governmental agencies. Conditions determined to be de minimis are not recognized 

environmental conditions. Additionally, the term historical REC refers to an enviromental 

condition associated with the Subject Property, including a past release of any hazardous 

substance or petroleum product, which in the past would have been considered a REC, but has 

since been remediated. Historical RECs will therefore be included in this Phase I ESA (ASTM 

2006). 

1.3 LIMITATIONS AND EXCEPTIONS 

No Environmental Site Assessment can completely eliminate uncertainty regarding the potential 

for RECs in connection with a property. Conformance of this assessment with ASTM Standard 

Practice E 1527-05 will reduce, but not eliminate, uncertainty regarding the potential for RECs in 

connection with the Subject Property. While AES has made every effort to discover and interpret 

available historical and current information on the property within the time available, the 

possibility for undiscovered contamination to be present remains. AES’s report is a best-effort 

collection and interpretation of available information consistent with industry standards for the 

completion of Phase I ESAs. 

This site assessment is based on a site reconnaissance of the Subject Property, searches of 

government regulatory agency databases that identify hazardous material sites, and interviews 

with individuals that are knowledgeable of the previous and current uses of the Subject Property. 

Neither physical testing of soil or groundwater nor surveys for asbestos containing building 

materials (ACM) and lead-based paint were not within the scope of this assessment. 

1.4 METHODOLOGY 

The following sub-sections describe the methods used and the data sources consulted to 

accomplish each task of this Phase I ESA.

1.4.1 HISTORICAL REVIEW 

Historic land uses were researched in an effort to identify potential sources of hazardous 

substances at or near the Subject Property. Historic aerial photographs (Appendix A) and

topographic maps (Appendix B) were examined for the indications of aboveground storage 

tanks, industrial buildings, gas station canopies and/or pump islands, as well as other indications 

of bulk hazardous material storage within the study area. 
1.0 Introduction

January 2009 Phase I Environmental Site Assessment

1.4.2 DATABASE SEARCHES 

Database searches were made for records of known storage tank sites and known sites of 

hazardous materials generation, storage, or contamination. Available information from Federal, 

State, and local agency lists of: (a) known or potential hazardous waste sites and landfills; (b) 

sites currently under investigation for environmental violations; (c) sites which manufacture, 

generate, use, store, and/or dispose of hazardous materials or hazardous wastes; (d) sites which 

have underground storage tanks (USTs); and (e) sites with recorded violations of regulations 

concerning USTs and hazardous materials/hazardous wastes. The database search is intended to 

identify facilities that may have the potential to impact surface and subsurface conditions on the 

Subject Property. A full listing of sites within the vicinity of the Subject Property is provided in 

Appendix E.

1.4.3 SITE RECONNIASSANCE 

Melissa Oberti from AES conducted a reconnaissance inspection of the Subject Property and 

adjacent properties on December 29, 2008. Ms. Oberti was assisted by David Sawyer and 

Bibiana Sparks. The purpose of the site reconnaissance is to look for obvious physical 

indications of improper hazardous substance or petrochemical disposal such as stained soil or 

asphalt, stressed vegetation, sumps, partially buried drums, and bulk underground fuel storage 

tanks. In addition, adjacent properties were visually inspected to the extent possible without 

trespassing on private property to determine if current land uses would affect the planned uses of 

Subject Property. 

1.5 DEVIATIONS AND DATA GAPS 

ASTM Standard E 1527-05 requires any significant data gaps, deviations, and deletions from the 

ASTM Standard to be identified and commented on in the Phase I. The significance of the data 

gaps—whether or not they affected the ability to identify a REC on the Subject Property or 

adjacent properties—is also required to be identified. Due to the rural nature of the Subject 

Property, Sanborn maps were not available. The lack of Sanborn maps is not considered a 

significant data gap since land uses were easily identified on the historical aerial photographs. 

1.6 CREDENTIALS 

Melissa Oberti has prepared this report under the professional supervision of, David Zweig P.E., 

who qualifies as an environmental professional (EP) as defined in the ASTM Standard E 1527-

05. Melissa Oberti and David Zweig’s signatures appear in Section 6.0 of this Phase I and their 

resumes are included as Appendix H.

2.3 LOCAL ENVIRONMENTAL RECORDS SOURCES 

Local Environmental Agency 

AES submitted a request for available files for review at the Sonoma County Environmental 

Health Department (SCEHD) on December 30, 2008, regarding potential environmental issues at 

the Subject Property. SCEHD had no records pertaining to the Subject Property.

Department of Planning and Zoning 

AES reviewed the Sonoma County Planning Department website (http://www.sonomacounty.org/prmd/docs/zoning/index.htm) for the zoning of the Subject Property. The Subject 

Property is zoned AR (Agriculture and Residential District), which is appropriate for the current 

location.

Electrical Utility Company 

AES spoke with a representative (name withheld) on December 30, 2008 of Pacific Gas & 

Electric (PG&E), who confirmed that PG&E provides electrical utilities to the Subject Property. 

Other Local Environmental Records Sources 

AES reviewed the California Regional Water Quality Control Board’s (CRWQCB) Geotracker 

website (www.geotracker.swrcb.ca.gov) for listings of USTs, LUSTs, and spill cases at the 

property. The Geotracker website had no listing of USTs, LUSTs, and spill cases at the Subject 

Property. 

2.4 HYDROLOGY 

The Subject Property has one domestic well located on the property. Based on the Department of 

Water Resources Groundwater Data, the depth to groundwater is approximately 100 to 125 feet 

below ground surface (bgs). Estimated groundwater levels and/or flow direction(s) may vary due 

to seasonal fluctuations in precipitation, local usage demands, geology, underground structures, 

or dewatering operations. The surface water from the Subject Property drains primarily from 

west to east, beginning at the northwest corner of parcel 066-191-017. Surface water flow 

continues eastward through the northern half of parcel 066-191-022 and eventually ends up in the 

Mark West Creek, which is located along the eastern border of parcel 066-191-022. 

2.5 GEOLOGY AND SOIL 

Soils in the vicinity of the Subject Property are variable and include gravelly sandy loam at 

depths ranging between zero and 5 inches below ground surface (bgs). Soils at depths ranging 

between 5 and 27 inches bgs are classified as loam. Soils at depths ranging between 27 and 72 

inches bgs are classified as gravelly clay loam. The hydrologic group for this area is Class B, 

moderate infiltration rates and the soils in the property vicinity are moderately well and well-

January 2009 Phase I Environmental Site Assessment 

drained soils with moderately coarse textures. Additionally, the rock stratigraphic unit at the 

Subject Property is Cenozoic, which is in the Quaternary system and series (EDR, 2009). 

2.6 CURRENT USES OF THE SUBJECT PROPERTY

The Subject Property is currently developed with one private residence with a detached barn, a 

mobile home, four chicken coops and several pastures. One domestic well is located on the 

Subject Property and one 500-gallon propane tank. The conditions observed during the site 

reconnaissance are described and illustrated in Section 3.2 of this Phase I ESA. Additionally, site 

photos showing conditions of the Subject Property during the site visit are shown in Figures 4, 

through 6 following page 3-2. 

2.7 HISTORIC USES OF THE SUBJECT PROPERTY 

2.7.1 AERIAL PHOTOGRAPHS 

AES reviewed available historic aerial photographs (Appendix A) for information regarding past 

uses of the Subject Property and surrounding areas. The following aerial photographs were 

available for review: 1952 (1”=555’), 1965 (1”=555’), 1974 (1”=541’), 1982 (1”=690’), 1993 

(1”=666’), 1998 (1”=666’) and 2005 (1”=484’). Aerial photographs were of varying scale and 

clarity. Historical aerial images offer detailed review of previous land uses on the Subject 

Property and adjacent properties. 

Review of the 1952, 1965, and 1974 aerial photos reveals the Subject Property to be mostly 

undeveloped with the exception of three structures located on parcel 066-191-017. Additionally, 

it appears that four structures are located on parcel 066-191-022. Windsor River Road is located 

to the north beyond which appears to be undeveloped land. Mark West Creek is located to the 

east beyond which appears to be a Ranch with several structures. Agriculture is located to the 

south and undeveloped land is located to the west. The access road appears to be developed to 

the east and west of the property. 

The 1982, 1993, 1998 and 2005 aerial photos show the Subject Property as mostly developed 

with the private residence and barn located on parcel 066-191-017. Additionally, is appears that 

the chicken coops are located on parcel 066-191-022. The Subject Property appears to be 

developed in its current configuration. Windsor River Road is located to the north beyond which 

appears to be a residential community. Mark West Creek is located to the east beyond which 

appears to be several homes. Agriculture and vineyards are located to the south and undeveloped 

land is located to the west. The access road appears to be developed to the east and west of the 

property.

SECTION 3.0 

SITE RECONNAISSANCE AND INTERVIEWS 

3.1 OBJECTIVE 

The objective of the site reconnaissance is to identify current or historic hazardous materials 

involvement on the Subject Property or in the vicinity of the Subject Property. Hazardous 

materials involvement or signature environmental conditions include the presence or likely 

presence of any hazardous materials or petroleum products that indicate an existing release, past 

release, or a threat of release into any structure on the property, soil, surface water, or 

groundwater. Signs of possible hazardous materials involvement would include any indications 

of underground storage tanks existing on the Subject Property, stained soils and/or unusual odors 

originating from the Subject Property, indications of an excavation or removal of soils, including 

patched asphalt and large debris piles, and other obvious signs of hazardous materials 

involvement. At the time of the property reconnaissance, the weather was cloudy, clear, and cold. 

There were no visibility limitations due to weather conditions. 

Interviews included contacting individuals familiar with the Subject Property and adjacent 

properties that are knowledgeable of historic and existing conditions relative to hazardous 

materials.

SECTION 4.0 

RECORDS REVIEW 

4.1 DATABASE SEARCH

Database searches were conducted for records of known storage tank sites and known sites of 

hazardous materials generation, storage, and/or contamination within one mile from a point 

roughly equivalent to the center of the Subject Property. The environmental database review was 

accomplished by using the services of a computerized search firm Environmental Data 

Resources, Inc. (EDR) of Milford, Connecticut. EDR uses a geographical information system to 

plot locations of past or previous hazardous materials involvement. AES reviewed the EDR 

report to determine if the Subject Property and adjacent sites are listed on regulatory agency 

databases. The purpose is to determine if adjacent hazardous materials sites will impact surface 

and/or subsurface conditions on the Subject Property. Included in the EDR database report was a 

list of “unmapped sites.” AES reviewed the list of unmapped sites for the properties that may be 

located within the search radius specified for each governmental database. These sites do not 

appear to be located within the applicable search radius of the Subject Property. The complete 

list of reviewed databases is provided in the EDR report, included in Appendix E and is 

summarized in Table 1. 

4.2 HAZARDOUS MATERIALS INVOLVEMENT 

A regulatory agency database report was performed to identify locations of past and/or current 

hazardous materials involvement. Regulatory agency databases were searched for records of 

known storage tank sites and known sites of hazardous materials generation, storage, or 

contamination, or where violations pertaining to storage and/or use of hazardous materials have 

occurred. Databases were searched for sites and listings up to one mile from a point roughly 

equivalent to the center of Subject Property. Although a site may be listed within the database 

report, this does not mean the site is currently contaminated or will impact the environmental 

quality of the Subject Property. It should be noted that the database search is only as accurate as 

the data entered into the government agency maintained databases and the date on which those 

databases were last updated. Installation of underground storage tanks or hazardous material 

releases, if not reported to the appropriate agency, would not be listed on any of the databases 

searched.

SURROUNDING SITES: SEARCH RESULTS

Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on

a relative (not an absolute) basis. Relative elevation information between sites of close proximity

should be field verified. Sites with an elevation equal to or higher than the target property have been

differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed

data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

FEDERAL RECORDS

FUDS: The Listing includes locations of Formerly Used Defense Sites Properties where the US Army

Corps Of Engineers is actively working or will take necessary cleanup actions.

 A review of the FUDS list, as provided by EDR, and dated 12/31/2007 has revealed that there is 1 FUDS

 site within approximately 1 mile of the target property.

Archived sites are sites that have been removed and archived from the inventory of CERCLIS sites. Archived status

indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined

no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates

this decision was not appropriate or other considerations require a recommendation for listing at a later time.

This decision does not necessarily mean that there is no hazard associated with a given site; it only means that,

based upon available information, the location is not judged to be a potential NPL site.

US BROWNFIELDS: A Listing of Brownfields Sites

Included in the listing are brownfields properties addresses by Cooperative Agreement Recipients and brownfields

properties addressed by Targeted Brownfields Assessments. Targeted Brownfields Assessments-EPA’s Targeted Brownfields

Assessments (TBA) program is designed to help states, tribes, and municipalities--especially those without EPA

Brownfields Assessment Demonstration Pilots--minimize the uncertainties of contamination often associated with

brownfields. Under the TBA program, EPA provides funding and/or technical assistance for environmental assessments

at brownfields sites throughout the country. Targeted Brownfields Assessments supplement and work with other efforts

under EPA’s Brownfields Initiative to promote cleanup and redevelopment of brownfields. Cooperative Agreement

Recipients-States, political subdivisions, territories, and Indian tribes become Brownfields Cleanup Revolving

Loan Fund (BCRLF) cooperative agreement recipients when they enter into BCRLF cooperative agreements with the

U.S. EPA. EPA selects BCRLF cooperative agreement recipients based on a proposal and application process. BCRLF

cooperative agreement recipients must use EPA funds provided through BCRLF cooperative agreement for specified

brownfields-related cleanup activities.

Uranium ore was mined by private companies for federal government use in national defense programs. When the mills

shut down, large piles of the sand-like material (mill tailings) remain after uranium has been extracted from

the ore. Levels of human exposure to radioactive materials from the piles are low; however, in some cases tailings

were used as construction materials before the potential health hazards of the tailings were recognized.

Site Mitigation and Brownfields Reuse Program Facility Sites with Deed Restrictions & Hazardous Waste Management

Program Facility Sites with Deed / Land Use Restriction. The DTSC Site Mitigation and Brownfields Reuse Program

(SMBRP) list includes sites cleaned up under the program’s oversight and generally does not include current

or former hazardous waste facilities that required a hazardous waste facility permit. The list represents deed

restrictions that are active. Some sites have multiple deed restrictions. The DTSC Hazardous Waste Management

Program (HWMP) has developed a list of current or former hazardous waste facilities that have a recorded land

use restriction at the local county recorder’s office. The land use restrictions on this list were required by

the DTSC HWMP as a result of the presence of hazardous substances that remain on site after the facility (or

part of the facility) has been closed or cleaned up. The types of land use restriction include deed notice, deed

restriction, or a land use restriction that binds current and future owners.

EDR PROPRIETARY RECORDS

Manufactured Gas Plants: EDR Proprietary Manufactured Gas Plants

The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)

compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s

to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture

of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,

such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds

are potentially hazardous to human health and the environment. The byproduct from this process was frequently

disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil

and groundwater contamination.

TOPOGRAPHIC INFORMATION

USGS 7.5’ Digital Elevation Model (DEM)

Source: United States Geologic Survey

EDR acquired the USGS 7.5’ Digital Elevation Model in 2002 and updated it in 2006. The 7.5 minute DEM corresponds

to the USGS 1:24,000- and 1:25,000-scale topographic quadrangle maps. The DEM provides elevation data

with consistent elevation units and projection.

Scanned Digital USGS 7.5’ Topographic Map (DRG)

Source: United States Geologic Survey

A digital raster graphic (DRG) is a scanned image of a U.S. Geological Survey topographic map. The map images

are made by scanning published paper maps on high-resolution scanners. The raster image

is georeferenced and fit to the Universal Transverse Mercator (UTM) projection.

HYDROLOGIC INFORMATION

Flood Zone Data: This data, available in select counties across the country, was obtained by EDR in 1999 from the Federal

Emergency Management Agency (FEMA). Data depicts 100-year and 500-year flood zones as defined by FEMA.

NWI: National Wetlands Inventory. This data, available in select counties across the country, was obtained by EDR

in 2002 and 2005 from the U.S. Fish and Wildlife Service.

HYDROGEOLOGIC INFORMATION

AQUIFLOW Information System R

Source: EDR proprietary database of groundwater flow information

EDR has developed the AQUIFLOW Information System (AIS) to provide data on the general direction of groundwater

flow at specific points. EDR has reviewed reports submitted to regulatory authorities at select sites and has

extracted the date of the report, hydrogeologically determined groundwater flow direction and depth to water table

information.

The U.S. Department of Agriculture’s (USDA) Natural Resources Conservation Service (NRCS) leads the national

Conservation Soil Survey (NCSS) and is responsible for collecting, storing, maintaining and distributing soil

survey information for privately owned lands in the United States. A soil map in a soil survey is a representation

of soil patterns in a landscape. Soil maps for STATSGO are compiled by generalizing more detailed (SSURGO)

soil survey maps.

SSURGO: Soil Survey Geographic Database

Telephone: 800-672-5559

SSURGO is the most detailed level of mapping done by the Natural Resources Conservation Services, mapping

scales generally range from 1:12,000 to 1:63,360. Field mapping methods using national standards are used to

construct the soil maps in the Soil Survey Geographic (SSURGO) database. SSURGO digitizing duplicates the

original soil survey maps. This level of mapping is designed for use by landowners, townships and county

natural resource planning and management.

REPRESENTATIVE

PROJECTS  Defense Distribution Region West Sharpe Depot Effluent and Receiving 

Water Quality Assessment, Lathrop, California. Under contract to the US 

Army Corps of Engineers, prepared an ERWQA for the depot's wastewater 

treatment plant effluent discharge. Effluent is treated at a secondary facility onsite, and discharged into an irrigation ditch that is tributary to French Camp 

Slough. Water quality concerns associated with the implementation of the Inland 

Surface Water Plan prompted the Regional Water Quality Control Board to 

require an ERWQA as a condition in the plant's Waste Discharge Requirements. 

Based on a limited number of lab tests, a work plan was prepared for the ERWQA 

to assess the impact of continued effluent discharges on the receiving water and 

possibly lead to treatment process and/or operational modifications. 

 Sacramento Municipal Utilities District Phase I and II Environmental 

Assessments. Performed Phase I and Phase II environmental site assessments on 

two cogeneration plant sites. The assessments consisted of records searches, 

interviews with representatives from regulatory agencies, field reconnaissance, 

sampling of surface soils, laboratory testing, and analysis of data. The 

assessments resulted in recommendations regarding the need for additional 

subsurface investigations and the risks associated with disposing of soil from the 

sites.

 City of Willits Sanitary Survey, Mendocino County. Managed the preparation 

of a watershed sanitary survey for the City Water Department for submission to 

the Department of Health Services to comply with the California Surface Water 

Treatment Regulation. In accordance with AWWA guidelines, the survey 

identifies potential contaminant sources within the watershed, and suggests 

methods for effectively managing the watershed. Potential contaminant sources 

within the 3,200-acre watershed include septic systems, mining, and a police 

shooting range. 

 Carmichael Water District Bajamont Way Phase I Environmental Site 

Assessment and Disposal Area Preliminary Assessment. Performed a Phase 1 

environmental assessment on the District's Corporation Yard site. The assessment 

consisted of a records search, interviews with representatives from regulatory 

agencies, field reconnaissance, sampling of surface soils, laboratory testing, and 

analysis of data. The assessment resulted in recommendations regarding the need 

for additional subsurface investigations and the risks associated with disposing of 

soil from the site. A preliminary assessment of a spoils disposal area at the site 

was also performed. 

 City of San Leandro Groundwater Monitoring Program. Developed and 

implemented a groundwater monitoring program for the City's Dredged Material 

Management Site, adjacent to San Francisco Bay. The site is used to dewater 

dredged material from the City's marina prior to land disposal. As a condition of 

the City's NPDES permit, ESA developed and implemented a groundwater 

investigation that included the installation and quarterly sampling of six 

monitoring wells. Four quarterly reports were prepared and submitted to the 

Regional Water Quality Control Board.

 Auto Park Treatment Tank Relocation Engineering, Environmental Review, 

and Land Acquisition. Relocated Calgon activated carbon adsorption system, 

consisting of two tanks each with 20,000 pounds of granular activated carbon. 

Project included installing water and sewer pipelines, booster pump station, and 

electronic controls, so as to allow continued use of a 1,000+ gpm well. The 

treatment system had been temporarily sited as an emergency measure to treat 

PCE contamination discovered in water from an existing well. Community 

concerns about visual impacts necessitated relocation. 

Strasbaugh Well Nitrate Treatment Engineering Studies. Studied the 

feasibility of providing nitrate removal for a contaminated groundwater source. 

Proven groundwater supplies were unusable because of nitrate contamination in 

the area. The contamination was the result of decades of intensive agricultural 

activity. An ion exchange process designed to remove nitrates from well water, 

and supporting infrastructure, was evaluated.

 American I Cogeneration Facility Spill Prevention Control and 

Countermeasure Plan. In cooperation with Sage Environmental, prepared a 

SPCCP for a cogeneration facility in King City. The American I facility uses a 

gas turbine cogeneration unit to generate electricity and provide steam and hot 

water to a neighboring food processing plant. Because of the large quantities of 

fuels and other chemicals stored at the facility, a SPCCP was required by the 

Regional Water Quality Control Board (RWQCB). In requiring the SPCCP, the 

RWQCB was implementing the regulations contained in Title 40 of the Code of 

Federal Regulations, Part 112. The SPCCP consists of an inventory of storage 

tanks and containment systems at the facility and recommendations to prevent 

hazardous materials from being released into nearby surface waters. 

 Defense Distribution Region West Sharpe Depot Storm Water Pollution 

Prevention Plan, Lathrop, California. Under contract to the US Army Corps of 

Engineers, prepared a SWPPP for the 300 acre Sharpe Depot. The depot receives, 

warehouses, and ships out military supplies and equipment. Shipments of bulk 

chemicals, mechanical parts, weapons, ammunition, and supplies arrive at the 

depot by air, rail, and truck. Previous spills at the depot have caused groundwater 

contamination and required remedial actions. To comply with Regional Water 

Quality Control Board NPDES permit requirements, a SWPPP was prepared that 

inventoried possible sources of stormwater pollution, and recommended measures 

to prevent those pollutants from entering storm water.

SECTION 1.0

INTRODUCTION

1.1 PURPOSE 

Analytical Environmental Services (AES) has prepared this Environmental Site Assessment 

(ESA) in conformance with the Bureau of Indian Affairs (BIA) guidelines (602 DM Chapter 2) 

and the American Society for Testing and Materials (ASTM) Standard Practice E 1527-05, which 

specifies the appropriate inquiry requirement for the innocent landowner defense under the 

Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). This 

ESA encompasses one legal parcel of approximately 1.25 acres, located in the County of 

Sonoma, California (Figure 1). As such, the use of the term “Subject Property” refers to the 

entire 1.25-acre property unless otherwise stated. The purpose of this assessment is to identify 

Recognized Environmental Conditions (RECs) that may affect future uses of the Subject 

Property. 

This ESA covers the Subject Property, adjacent areas, and surrounding known sources of 

contamination, up to 1.0 mile from the Subject Property. A site reconnaissance inspection of the 

Subject Property and adjacent properties was performed and relevant database listings of 

hazardous materials sites, waste generators, and underground storage tanks were reviewed (EDR, 

2009). AES also reviewed historical aerial photographs for the Subject Property. Years available 

for review were 1952, 1965, 1974, 1982, 1993, 1998, and 2005. 

1.2 RECOGNIZED ENVIRONMENTAL CONDITIONS 

The term REC refers to the presence or likely presence of any hazardous substances or petroleum 

products on a property under conditions that indicate an existing release, a past release, or a 

material threat of release of any hazardous substances or petroleum products into structures on the 

property or into the ground, groundwater, or surface water of the property. The term includes 

hazardous substances or petroleum products even under conditions in compliance with laws. The 

term is not intended to include de minimis conditions that generally do not present a material risk 

of harm to public health or the environment and that generally would not be the subject of an 

enforcement action if brought to the attention of appropriate governmental agencies. 

Additionally, the term historical REC refers to an environmental condition associated with the 
Lytton 1.25-Acre Phase I ESA / 207513

1.0 Introduction 

 

Analytical Environmental Services 1-3 Lytton 1.25-Acres 

207513 Phase I Environmental Site Assessment

Subject Property, including a past release of any hazardous substance or petroleum product, 

which in the past would have been considered a REC, however such condition has since been 

remediated. Historical RECs will therefore be included in this Phase I ESA (ASTM, 2006). 

1.3 LIMITATIONS AND EXCEPTIONS 

No ESA can completely eliminate uncertainty regarding the potential for RECs in connection 

with a property. Conformance of this assessment with ASTM Standard Practice E 1527-05 will 

reduce, but not eliminate, uncertainty regarding the potential for RECs in connection with the 

Subject Property. While AES has made every effort to discover and interpret available historical 

and current information on the property within the time available, the possibility for undiscovered 

contamination to be present remains. AES’s report is a best-effort collection and interpretation of 

available information consistent with industry standards for the completion of Phase I ESAs. 

This ESA is based on a site reconnaissance of the Subject Property, searches of government 

hazardous materials databases, and interviews with individuals familiar with the historical uses of 

the Subject Property. Physical testing of soil or groundwater was not within the scope of this 

assessment. Asbestos containing building materials (ACM) and lead-based paint surveys were 

not included. Information was obtained for this ESA to comply with ASTM guidelines. 

1.4 METHODOLOGY 

A variety of data sources were consulted in completing this Phase I ESA. The following subsections describe the methods used and the data sources consulted to accomplish each task.

1.4.1 HISTORICAL REVIEW 

Previous land uses and history of the Subject Property were researched in an effort to identify 

RECs at or near the Subject Property. Historical aerial photographs (Appendix A) and

topographic maps (Appendix B) from different decades were examined for the presence of 

aboveground storage tanks, industrial buildings, gas station canopies and/or pump islands, as well 

as other indications of bulk hazardous material storage within the study area. Sanborn Fire 

Insurance Maps (Appendix C) document historical property use through abbreviations and map 

symbols that identify commercial, industrial, residential and other land uses. 

1.4.2 DATABASE SEARCHES 

Database searches were conducted for records of known storage tank sites and known sites of 

hazardous materials generation, storage, or release. Available information from federal, state, 

and local agency lists of: (a) known or potential hazardous waste sites and landfills; (b) sites 

currently under investigation for environmental violations; (c) sites which manufacture, generate, 
1.0 Introduction 

 

Analytical Environmental Services 1-4 Lytton 1.25-Acres 

207513 Phase I Environmental Site Assessment

use, store, and/or dispose of hazardous materials or hazardous wastes; (d) sites which have 

underground storage tanks (USTs); and (e) sites with recorded violations of regulations 

concerning USTs and hazardous materials/hazardous wastes. The database search is intended to 

identify facilities that may have the potential to impact surface and subsurface conditions on the 

Subject Property. A full listing of sites within the vicinity of the Subject Property is provided in 

Appendix D.

1.4.3 SITE RECONNIASSANCE 

Trenton Wilson from AES conducted a reconnaissance inspection of the Subject Property and 

adjacent properties on October 8, 2009. The purpose of the site reconnaissance is to examine for 

obvious physical indications of improper hazardous substance or petrochemical disposal such as 

stained soil or asphalt, stressed vegetation, sumps, partially buried drums, bulk underground fuel 

storage tanks, and other obvious signs of hazardous materials involvement. In addition, adjacent 

properties were visually inspected to the extent possible without trespassing on private property 

to determine if current land uses would affect the planned uses of Subject Property. 

1.5 DEVIATIONS AND DATA GAPS 

ASTM Standard 1527-05 requires any significant data gaps, deviations and deletions from the 

ASTM Standard to be identified and commented on in the Phase I. A significant data gap would 

be one that affected the ability to identify a REC on the Subject Property or adjacent properties. 

Due to the rural location of the Subject Property, Sanborn Fire Insurance maps were not available 

for the Subject Property. Because there is no historical data or physical indications that the 

property has ever been developed or occupied by a business that would have produced hazardous 

materials, the lack of Sanborn Fire Insurance maps is not considered a significant data gap for this 

Phase I ESA.

1.6 CREDENTIALS 

Trenton Wilson prepared this report under the professional supervision of David Zweig, P.E., 

both of whom qualify as environmental professionals (EPs) as defined in the ASTM Standard 

1527-05 [40 CFR §312.10(b)]. The signatures of Trenton Wilson and David Zweig appear in 

Section 6.0 of this Phase I and their resumes are included as Appendix G.

topography of the Subject Property ranges in elevation from approximately 117 feet to 121 feet 

above mean sea level (amsl), increasing slightly in elevation from east to west. One relatively 

modern single-story single-family home, a two-car garage, a water treatment building, two 

relatively modern single-story storage buildings, and one aged two-story storage structure are 

located within the Subject Property’s boundaries. The residential and irrigation water demands 

are met by an on-site well with septic systems for wastewater treatment. 

Regional access is provided by US Highway 101 (US 101), which runs in a general south-north 

direction and is located 1.3 miles east of the Subject Property. Local access to the Subject 

Property from US 101 is provided by Windsor River Road, which is a two-lane County road that 

traverses east for two miles from the Old Redwood Highway near US 101 to Eastside Road to the 

west of the Subject Property. The right-of-way for Windsor River Road adjoins the northern 

boundary of the walnut orchard of the Subject Property. Direct access to the Subject Property is 

off Pyne Road, an unmarked access road that adjoins the eastern boundary of the Subject Property 

originating off Windsor River Road and terminating southwest of the Subject Parcel (Figure 3). 

2.3 LOCAL ENVIRONMENTAL RECORDS SOURCES

Department of Planning and Zoning 

AES reviewed the Sonoma County Planning Department website (http://www.sonomacounty.org/prmd/docs/zoning/index.htm) for the zoning of the Subject Property. The Subject 

Property is zoned AR (Agriculture and Residential District), which is consistent with the current 

location and land use. 

Electrical Utility Company 

AES spoke with a representative of the owners on October 23, 2009, who confirmed that PG&E 

provides electrical utilities to the Subject Property. 

Other Local Environmental Records Sources 

AES reviewed the California Regional Water Quality Control Board’s (CRWQCB) Geotracker 

website for listings of underground storage tanks (USTs), leaking underground storage tanks 

(LUSTs), or spill cases in association with petroleum chemicals at the Subject Property (SWRCB, 

2008). The Geotracker website had no listing of USTs, LUSTs, and spill cases at the Subject 

Property. The nearest listing is approximately 0.89 miles southwest of the Subject Property in 

response to an UST that was removed in 1991 showing signs of leakage. 

2.4 HYDROLOGY

One domestic well is located on the Subject Property. Based on the Department of Water 

Resources groundwater data (reference well located 0.30 miles west from the Subject Property), 

the depth to groundwater ranges from approximately 113 to 127 feet below ground surface (bgs) 

with a groundwater gradient generally towards the east towards the valley (DWR, 2009). 

Estimated groundwater levels and/or flow direction(s) may vary due to seasonal fluctuations in 

precipitation, local usage demands, geology, underground structures, or dewatering operations. 

From the walnut orchard, surface water drains primarily toward roadside drainages to the north. 

From the residential area, surface water primarily drains to the south through culverts and a manmade drainage ditch that discharges to an off-site drainage that flows west to east.

2.5 GEOLOGY AND SOIL

AES reviewed The EDR-Radius Map with Geocheck regulatory database report (EDR database 

report). According to information provided in the EDR database report, the rock stratigraphic 

unit at the Subject Property is Cenozoic, which is in the Quaternary system and series. Soils in 

the vicinity of the Subject Property include loam at depths ranging between zero and 14 inches 

below ground surface (bgs). Soils at depths ranging between 14 and 22 inches bgs are classified 

as sandy clay loam. Soils at depths ranging between 22 and 29 inches bgs are classified as clay. 

Soils at depths ranging between 29 and 57 inches bgs are classified as cemented. The hydrologic 

group rating for soils in this area is generally Class C, which indicates soils that exhibit slow 

water infiltration rates with soil layers impeding the downward movement of water.

2.6 CURRENT USES OF THE SUBJECT PROPERTY

Trenton Wilson from AES performed a site reconnaissance survey of the Subject Property on 

October 8th, 2009. The Subject Property is comprised of a small walnut orchard (approximately 

8 trees) along the northern third of the property with the remainder of the property consisting of 

residential landscaped and paved areas. The Subject Property is developed with a single-family 

home and associated storage structures. Site photos showing conditions of the Subject Property 

during the site visit are shown in Figure 4 in Section 3.0. 

2.7 HISTORIC USES OF THE SUBJECT PROPERTY

2.7.1 AERIAL PHOTOGRAPHS

AES reviewed available historic aerial photographs (Appendix A) for information regarding past 

uses of the Subject Property and surrounding areas. The following aerial photographs were 

available for review: 1952 (1”=555’), 1965 (1”=333’), 1974 (1’=541’), 1982 (1”= 690’), 1993 

(1”= 666’), 1998 (1”= 666’),and 2005 (1”= 604’). Aerial photographs were of varying scale and 

clarity. Historical aerial images offer detailed review of previous land uses on the Subject 

Property and adjacent properties. 

1952 and 1965 

The Subject Property is developed with a small orchard and several structures. Windsor River 

Road is visible to the north of the Subject Property and Pyne Road is visible to the west of the 

property. The orchard appears to occupy the same third of the Subject Property as existing 

conditions. Various other trees are shown on the Subject Property that do not currently exist, 

blocking the view of the lower two-thirds of the Subject Property, although the area appears to be 

developed for residential use. The adjacent properties to the north, east, and west appear to be 

used for agriculture, with a former prisoner of war camp (Appendix D) clearly visible to the 

northwest of the Subject Property. Further details on this camp are provided in Section 4.2.2. To 

the south/southeast, various agricultural buildings are visible.

1974 and 1982 

The subject property is not very discernable in the 1974 and 1982 aerial photos; however 

conditions appear to be consistent with the 1952 and 1965 aerial photographs, except for the 

agricultural buildings south and southeast of the property. The walnut orchard is discernable and 

appears to cover the same area of the parcel as existing conditions. Windsor River Road is visible 

to the north of the Subject Property and Pyne Road is visible to the west of the property. The 

agricultural buildings surrounding the Subject Parcel are indiscernible, appearing to have been 

removed. 
2.0 Site Description 

Analytical Environmental Services 2-6 Lytton 1.25-Acres 

207513 Phase I Environmental Site Assessment

1993 and 1998 

The 1993 and 1998 aerial photos indicate uses of the lower two-thirds of the Subject Property 

remain consistent with the residential use observed in the 1952 and 1965 aerial photographs. 

Windsor River Road is visible to the north of the Subject Property and Pyne Road is visible to the 

west of the property. The orchard appears to occupy the same third of the Subject Property as 

existing conditions and the residential portion of property appear consistent with existing 

conditions. The 1993 aerial photograph clearly shows that the agricultural buildings south and 

southeast of the Subject Property have been removed. 

2005

The 2005 aerial photo is indicative of existing conditions. Windsor River Road is visible to the 

north of the Subject Property and Pyne Road is visible to the west of the property. The orchard 

appears to occupy first third of the Subject Property and the residential portion of property 

appears consistent with existing conditions. The existing residence is visible in the center of the 

property as well are the garage and storage structures. 

2.7.2 HISTORIC TOPOGRAPHIC MAPS 

AES reviewed available historic USGS Topographic Quadrangles (Appendix B) for information 

regarding past uses of the Subject Property. The Healdsburg, California Topographic 

Quadrangle maps dated 1940, 1955, and 1993 were available for review. The 1940 topographic 

map depicts the Subject Property being developed with a residence. No other features are 

presented on the Subject Property. The 1955 topographic map depicts the residence on the 

Subject Property and two of the agricultural buildings on the adjacent property to the southeast. 

The 1955 topographic map does not indicate orchards on the Subject Property, consistent with 

on-site observations indicating the walnut orchard is for private use. The 1993 topographic map 

identifies the residence on the Subject Property and the removal of the agricultural structures. 

The 1993 topographic map does not identify the orchard on the Subject Property and indicates 

smaller structures south and southwest on adjacent properties. 

2.8 SANBORN FIRE INSURANCE MAPS 

Sanborn Fire Insurance Maps do not provide coverage of the Subject Property. Documentation of 

the lack of coverage is included in Appendix C.

2.9 OTHER PHYSICAL SETTING SOURCES 

Wetlands Map 

According to the Overview Map located with the regulatory database report, which references 

information provided by the National Wetlands Inventory (NWI) Map for the Healdsburg NWI 

Quad, no wetlands are located on the property. The closest wetland to the Property is located

SECTION 3.0 

SITE RECONNAISSANCE AND INTERVIEWS 

3.1 OBJECTIVE 

The objective of the site reconnaissance is to identify current or historic hazardous materials 

involvement on the Subject Property or in the vicinity of the Subject Property. Hazardous 

materials involvement or signature environmental conditions include the presence or likely 

presence of any hazardous materials or petroleum products that indicate an existing release, past 

release, or a threat of release into any structure on the property, soil, or groundwater. Signs of 

possible hazardous materials involvement would include any indications of underground storage 

tanks existing on the Subject Property, stained soils and/or unusual odors originating from the 

Subject Property, indications of an excavation or removal of soils, including patched asphalt and 

large debris piles, and other obvious signs of hazardous materials involvement. 

Interviews included contacting individuals familiar with the Subject Property and adjacent 

properties that are knowledgeable of historic and existing conditions relative to hazardous 

materials. 

3.2 SITE RECONNAISSANCE FINDINGS 

Trenton Wilson from AES conducted a site reconnaissance of the Subject Property on October 8, 

2009. Adjacent properties were observed to the extent possible without trespassing. Figure 4 

provides photographs that show the site conditions at the time of the site visit. Notable features 

and environmental conditions are summarized below: 

x The Subject Property comprises approximately 1.25 acres of partially developed land. 

The northern one-third of the Subject Property is planted with walnut orchards. The 

remainder of the Subject Property consists of a residential unit, two-story aged storage 

structure, two-car garage, and two single-story storage units. 

x A water well is located behind the residential storage shed, which houses a pressurized 

water tank and water softener. Approximately ten 50-pound bags of Diamond Crystals 

Pellets (salt pellets) for the water softener are stored within the shed. Additionally, 

individual containers of various pesticides and plant nutrients were stored in the shed 

(Photo 1). A majority of the chemicals were stored within approved commercial

containers and no surface staining or odor was observed inside or outside the shed. As 

shown in Photo 1, three 35-ounce coffee containers were marked as containing Sevin 

Lawn Insect Granules. According to the MSDS, Sevin Lawn Insect Granules contain the 

insecticide carbaryl. Carbaryl is a carbamate General Use Pesticide used for controlling 

over 100 species of insects on various edible crops include nut trees (Extoxnet, 1996). 

x No hazardous materials or indications of hazardous materials releases were observed 

within the storage buildings. 

x An electricity service line extends from the transformer off the Subject Property along the 

right of way of Windsor River Road to two power poles, one located in the walnut 

orchard and one near the residential storage shed. No transformers are located on the 

Subject Property. 

x Several piles of non-hazardous construction debris were noted on the Subject Parcel. 

Included within a pile of non-hazardous construction debris (Photo 2) were spent fire 

extinguishers and open containers of what appeared to be indoor latex paint (Photo 3).

x Two piles of earthen fill were observed on the southwestern portion of the Subject 

Property. The northern pile appears to represent excavated fill from the planting of 

ornamental shrubs and trees throughout the Subject Property. The southern pile (Photo

4) appears to represent removed pavement and vegetation from the Subject Property. 

Pieces of asphalt were visible within the pile. The asphalt appears to have been removed 

from the access driveway off Pyne Road to install a drainage line from the front yard of 

the residence to the culverted drainage that discharges off site to the south. A white 

asphalt patch is visible across the driveway.

3.3 ADJACENT PROPERTIES 

AES performed a survey of adjacent properties to the extent possible without trespassing. The 

purpose was to identify adjacent businesses and determine if current land uses would affect the 

planned use of the Subject Property. Adjacent land uses are described below. 

x North: Windsor River Road is located to the north. A power line with a pole mounted 

transformer was observed along the Windsor Creek Roadway right-of-way north of the 

property boundary. No leaks associated with the transformers were observed. 

x South: A horse ranch is located to the south of the Subject Property. A west-to-east 

drainage flows just beyond the southern boundary of the Subject Parcel. There are 

several aged structures related to agriculture and horse rearing located south of the 

Subject Property.

x West: Pyne Road is located to the west of the Subject Parcel. Beyond Pyne Road is a 

2.45 acre parcel for which a Phase I ESA was completed in February of 2009 concluding 

that no RECs exist on the property. 

x East: Horse grazing lands, which appeared to have been orchards in the past, adjoin the 

Subject Parcel to the east. The remnants of a building foundation are evident on both 

sides of eastern boundary of the Subject Parcel near the existing garage.

RECORDS REVIEW 

4.1 DATABASE SEARCH

Database searches were conducted for records of known storage tank sites and known sites of 

hazardous materials generation, storage, and/or contamination. Databases were searched for sites 

and listings up to one mile from the Subject Property. The environmental database review was 

accomplished by using the services of a computerized search firm Environmental Data 

Resources, Inc. (EDR). EDR uses a geographical information system to plot locations of past or 

previous hazardous materials involvement. AES reviewed the EDR report to determine if the 

Subject Property and adjacent sites are listed on regulatory agency databases. The purpose is to 

determine if adjacent sites will impact surface and/or subsurface conditions on the Subject 

Property. Included in the EDR database report was a list of “unmapped sites”. AES reviewed the 

list of unmapped sites for the properties that may be located within the search radius specified for 

each governmental database. These sites do not appear to be located within the applicable search 

radius of the Subject Property. The complete list of reviewed databases is provided in the EDR 

report, included in Appendix D and is summarized in Table 4-1. Information on past and/or 

current hazardous materials involvement involving adjacent properties is summarized in Section 

4.2.2. 

4.2 HAZARDOUS MATERIALS INVOLVEMENT 

A regulatory agency database report was performed to identify locations of past and/or current 

hazardous materials involvement. Regulatory agency databases were searched for records of 

known storage tank sites and known sites of hazardous materials generation, storage, or 

contamination, or where violations pertaining to storage and/or use of hazardous materials have 

occurred. Databases were searched for sites and listings up to one mile from a point roughly 

equivalent to the center of Subject Property. Although a site may be listed within the database 

report, this does not mean the site is currently contaminated or will impact the environmental 

quality of the Subject Property. It should be noted that the database search is only as accurate as 

the data entered into the government agency maintained databases and the date on which those 

databases were last updated. Installation of underground storage tanks or hazardous material 

releases, if not reported to the appropriate agency, would not be listed on any of the databases 

searched.

Analytical Environmental Services 4-4 Lytton 1.25-Acres 

207513 Phase I Environmental Site Assessment

4.2.2 ADJACENT PROPERTIES

Three sites were identified within one mile of the Subject Property. One site was listed as a 

former United States Army defense site, one site was listed on multiple databases for known 

contamination or for which there may be reasons to investigate further, and one site was listed 

three times regarding Proposition 65 notices for potential impacts to drinking water. 

The Windsor Prisoner of War Labor Camp (Labor Camp) (Appendix D) is located approximately 

0.27 miles northwest of the Subject Property and is listed on the FUDS database. The Labor 

Camp once comprised 66.74 acres approximately 1 mile west of the Town of Windsor, 6 miles 

south of Healdsburg. The site was relinquished to an unknown party in 1946 and then 

retransferred to the United States Department of Agriculture. Currently, three of the former 

bunkhouses are used as residences and open space is used for pastures. According to the 

database, no potential hazards related to Department of Defense activity have been located on the 

66.74 acre site. Based on the current regulatory status and lack of violations reported, this site is 

not likely to pose a risk to the environmental quality of the Subject Property. 

Windsor Fuel is located 0.96 miles northeast of the Subject Property adjacent to US 101 on the 

Old Redwood Highway. Windsor Fuel is a fuel distributor listed on the CERCLIS, FINDS, 

LUST, SLIC, and ENVIROSTOR databases. Windsor Fuel is also listed as operating under a 

National Pollution Discharge Elimination System (Clean Water Act Section 402) permit for 

industrial storm water discharge. The site is listed in response to the removal of several 

underground storage tanks and the identification of soil and groundwater contamination with 

heavy weight petroleum hydrocarbons. The extent of the contamination has been defined and the 

plume does not appear to be migrating. The listing status is currently open and verification 

monitoring is being performed. Based on the current regulatory status of a confined nonmigrating plume, distance from the project site, and lack of additional violations reported, this 

site is not likely to pose a risk to the environmental quality of the Subject Property. 

The facility at 340 Windsor River Road located 0.92 miles east of the Subject Property is listed as 

requiring a Proposition 65 notice to the surrounding community regarding a release that has the 

potential to impact drinking water supplies. Although there are three separate listings for the site, 

the date of report (October 16, 1992), incident description number, and Board file number are 

identical for all three listings. The incident is reported as a leak; however, no other information is 

provided. Based on the lack of additional listings in other governmental agency databases 

indicating no further action required and distance from the project site, this site is not likely to 

pose a risk to the environmental quality of the Subject Property. 
SECTION 5.0

FINDINGS AND CONCLUSIONS
Analytical Environmental Services 5-1 Lytton 1.25-Acres 

207513 Phase I Environmental Site Assessment

SECTION 5.0 

FINDINGS AND CONCLUSIONS 

This Phase I ESA was performed in conformance with the scope and limitations of ASTM 

Standard Practice E1527-05 and BIA guidelines (602 DM Chapter 2). Based on information 

gathered while conducting this Phase I ESA, AES observed the following environmental 

conditions:

x The 1.25-acre Subject Property is comprised of a cultivated walnut orchard, an occupied 

private residence and associated water treatment building, two single-story storage 

buildings, two-story storage structure, and one two-car garage. The earliest available 

historic aerial photographs from EDR show that the Subject Property was developed with 

orchards and residential structures in 1952. 

x Based on the visible architecture of the two-story storage structure (differing from the 

other structures, which were of similar construction and paint color) and conditions of the 

paint and nails, the structure may be older than 30 years old. 

x Several electric transformers attached to power poles are located adjacent to the Subject 

Property. No leaks were observed. 

x Non-hazardous debris consisting of excavated fill, wood, wire fencing and associated 

stakes, asphalt, and other standard non-hazardous materials were stored in four locations 

on the Subject Property. 

x One of the debris piles on the Subject Property contained spent fire extinguishers and 

open containers of what appeared to be dried latex paint. Four of the five containers did 

not contain lids and the substance inside each container was oily and colored. The 

presence of four open containers of what appeared to represent dried paint is considered a 

de minimis condition relating to the presence of hazardous materials on the Subject 

Property. As defined by ASTM Practice E 1527, de minimis conditions represent 

hazardous materials on a subject property that “generally do not present a threat to human 

health or the environment and that generally would not be the subject of an enforcement 

action if brought to the attention of appropriate governmental agencies” (Section 1.1.1). 

The identification of hazardous materials that are determined to be de minimis are not 

RECs.

x The residential shed storing the water tank contained various chemicals such as salt for 

water softening, pesticides, and gardening/landscaping chemicals that were stored within 

approved commercial containers. No surface staining or odor was observed inside or 

outside the shed. Three coffee cans were identified within the residential shed that were 

labeled as containing Sevin Lawn Insect Granules, which contain the General Use 

Pesticide carbaryl. Carbaryl is accepted for use in residential and agricultural settings 

and although the chemical is not being stored in approved commercial containers, the 

small quantities do not pose a risk to human health or the environmental quality of the 

Subject Property (Extoxnet, 1996). The presence of carbaryl stored in sealable coffee 

containers is considered to represent de minimis hazardous materials conditions, and is 

therefore not a REC. 

AES has performed a Phase I ESA in conformance with the scope and limitations of ASTM 

Practice E 1527 of 1270 Windsor River Road, the Subject Property. Any exceptions to, or 

deletions from, this practice are described in Section 1.0 of this report. This assessment has 

revealed no evidence of RECs in connection with the Subject Property. Based on the findings 

and conclusions of this Phase I ESA, AES has the following recommendations. 

x All non-hazardous and de minimis hazardous miscellaneous debris (including but not 

limited to building products, excavated asphalt, spent fire extinguishers, and assumed 

paint containers) that are not used as part of ongoing operations should be removed from 

the Subject Property and recycled or properly disposed at a licensed disposal facility. 

x The de minimis pesticides stored within coffee containers should either be removed from 

the Subject Property and disposed at a licensed disposal facility or the pesticide should be 

transferred to approved commercial containers according to manufacturer’s 

recommendations for appropriate handling and use of personal protective equipment. If 

the contents are transferred, the coffee containers previously storing the pesticides should 

be properly disposed at a licensed disposal facility. 

x The two-story storage structure should be assessed by qualified personnel for lead and 

asbestos if the structure is proposed for demolition or remodeling.

SURROUNDING SITES: SEARCH RESULTS

Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on

a relative (not an absolute) basis. Relative elevation information between sites of close proximity

should be field verified. Sites with an elevation equal to or higher than the target property have been

differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed

data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

ENVIROSTOR: The Department of Toxic Substances Control’s (DTSC’s) Site Mitigation and Brownfields

Reuse Program’s (SMBRP’s) EnviroStor database identifes sites that have known contamination or sites for which

there may be reasons to investigate further. The database includes the following site types: Federal

Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State

Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information

that was available in CalSites, and provides additional site information, including, but not limited to,

identification of formerly-contaminated properties that have been released for reuse, properties where

environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk

characterization information that is used to assess potential impacts to public health and the environment at

contaminated sites.

 A review of the ENVIROSTOR list, as provided by EDR, and dated 08/27/2009 has revealed that there is

 1 ENVIROSTOR site within approximately 1 mile of the target property.

CERCLIS-NFRAP: CERCLIS No Further Remedial Action Planned

Archived sites are sites that have been removed and archived from the inventory of CERCLIS sites. Archived status

indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined

no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates

this decision was not appropriate or other considerations require a recommendation for listing at a later time.

This decision does not necessarily mean that there is no hazard associated with a given site; it only means that,

based upon available information, the location is not judged to be a potential NPL site.

GOVERNMENT RECORDS SEARCHED / DATA CURRENCY TRACKING
Included in the listing are brownfields properties addresses by Cooperative Agreement Recipients and brownfields

properties addressed by Targeted Brownfields Assessments. Targeted Brownfields Assessments-EPA’s Targeted Brownfields

Assessments (TBA) program is designed to help states, tribes, and municipalities--especially those without EPA

Brownfields Assessment Demonstration Pilots--minimize the uncertainties of contamination often associated with

brownfields. Under the TBA program, EPA provides funding and/or technical assistance for environmental assessments

at brownfields sites throughout the country. Targeted Brownfields Assessments supplement and work with other efforts

under EPA’s Brownfields Initiative to promote cleanup and redevelopment of brownfields. Cooperative Agreement

Recipients-States, political subdivisions, territories, and Indian tribes become Brownfields Cleanup Revolving

Loan Fund (BCRLF) cooperative agreement recipients when they enter into BCRLF cooperative agreements with the

U.S. EPA. EPA selects BCRLF cooperative agreement recipients based on a proposal and application process. BCRLF

cooperative agreement recipients must use EPA funds provided through BCRLF cooperative agreement for specified

brownfields-related cleanup activities.

Site Mitigation and Brownfields Reuse Program Facility Sites with Deed Restrictions & Hazardous Waste Management

Program Facility Sites with Deed / Land Use Restriction. The DTSC Site Mitigation and Brownfields Reuse Program

(SMBRP) list includes sites cleaned up under the program’s oversight and generally does not include current

or former hazardous waste facilities that required a hazardous waste facility permit. The list represents deed

restrictions that are active. Some sites have multiple deed restrictions. The DTSC Hazardous Waste Management

Program (HWMP) has developed a list of current or former hazardous waste facilities that have a recorded land

use restriction at the local county recorder’s office. The land use restrictions on this list were required by

the DTSC HWMP as a result of the presence of hazardous substances that remain on site after the facility (or

part of the facility) has been closed or cleaned up. The types of land use restriction include deed notice, deed

restriction, or a land use restriction that binds current and future owners.

EDR PROPRIETARY RECORDS

EDR Proprietary Records

Manufactured Gas Plants: EDR Proprietary Manufactured Gas Plants

The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)

compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s

to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture

of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,

such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds

are potentially hazardous to human health and the environment. The byproduct from this process was frequently

disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil

and groundwater contamination.

207513 Phase I Environmental Site Assessment

SECTION 1.0

INTRODUCTION

1.1 PURPOSE 

Analytical Environmental Services (AES) has prepared this Environmental Site Assessment 

(ESA) in conformance with the Bureau of Indian Affairs (BIA) guidelines (602 DM Chapter 2) 

and the American Society for Testing and Materials (ASTM) Standard Practice E 1527-05, which 

specifies the appropriate inquiry requirement for the innocent landowner defense under the 

Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). This 

ESA encompasses one legal parcel of approximately 2.29 acres, located in the County of 

Sonoma, California (Figure 1). As such, the use of the term “Subject Property” refers to the 

entire 2.29-acre property unless otherwise stated. The purpose of this assessment is to identify 

Recognized Environmental Conditions (RECs) that may affect future uses of the Subject 

Property. 

This ESA covers the Subject Property, adjacent areas, and surrounding known sources of 

contamination, up to 1.0 mile from the Subject Property. A site reconnaissance inspection of the 

Subject Property and adjacent properties was performed and relevant database listings of 

hazardous materials sites, waste generators, and underground storage tanks were reviewed (EDR, 

2009). AES also reviewed historical aerial photographs for the Subject Property. Years available 

for review were 1952, 1965, 1974, 1982, 1993, 1998, and 2005. 

1.2 RECOGNIZED ENVIRONMENTAL CONDITIONS 

The term REC refers to the presence or likely presence of any hazardous substances or petroleum 

products on a property under conditions that indicate an existing release, a past release, or a 

material threat of release of any hazardous substances or petroleum products into structures on the 

property or into the ground, groundwater, or surface water of the property. The term includes 

hazardous substances or petroleum products even under conditions in compliance with laws. The 

term is not intended to include de minimis conditions that generally do not present a material risk 

of harm to public health or the environment and that generally would not be the subject of an 

enforcement action if brought to the attention of appropriate governmental agencies. 

Additionally, the term historical REC refers to an environmental condition associated with the 
Lytton 2.29-Acre Phase I ESA / 207513

1.0 Introduction 

 

Analytical Environmental Services 1-3 Lytton 2.29-Acres 

207513 Phase I Environmental Site Assessment

Subject Property, including a past release of any hazardous substance or petroleum product, 

which in the past would have been considered a REC, however such condition has since been 

remediated. Historical RECs will therefore be included in this Phase I ESA (ASTM, 2006). 

1.3 LIMITATIONS AND EXCEPTIONS 

No ESA can completely eliminate uncertainty regarding the potential for RECs in connection 

with a property. Conformance of this assessment with ASTM Standard Practice E 1527-05 will 

reduce, but not eliminate, uncertainty regarding the potential for RECs in connection with the 

Subject Property. While AES has made every effort to discover and interpret available historical 

and current information on the property within the time available, the possibility for undiscovered 

contamination to be present remains. AES’s report is a best-effort collection and interpretation of 

available information consistent with industry standards for the completion of Phase I ESAs. 

This ESA is based on a site reconnaissance of the Subject Property, searches of government 

hazardous materials databases, and interviews with individuals familiar with the historical uses of 

the Subject Property. Physical testing of soil or groundwater was not within the scope of this 

assessment. Asbestos containing building materials (ACM) and lead-based paint surveys were 

not included. Information was obtained for this ESA to comply with ASTM guidelines. 

1.4 METHODOLOGY 

A variety of data sources were consulted in completing this Phase I ESA. The following subsections describe the methods used and the data sources consulted to accomplish each task.

1.4.1 HISTORICAL REVIEW 

Previous land uses and history of the Subject Property were researched in an effort to identify 

RECs at or near the Subject Property. Historical aerial photographs (Appendix A) and

topographic maps (Appendix B) from different decades were examined for the presence of 

aboveground storage tanks, industrial buildings, gas station canopies and/or pump islands, as well 

as other indications of bulk hazardous material storage within the study area. Sanborn Fire 

Insurance Maps (Appendix C) document historical property use through abbreviations and map 

symbols that identify commercial, industrial, residential and other land uses. 

1.4.2 DATABASE SEARCHES 

Database searches were conducted for records of known storage tank sites and known sites of 

hazardous materials generation, storage, or release. Available information from federal, state, 

and local agency lists of: (a) known or potential hazardous waste sites and landfills; (b) sites 

currently under investigation for environmental violations; (c) sites which manufacture, generate, 
1.0 Introduction 

 

Analytical Environmental Services 1-4 Lytton 2.29-Acres 

207513 Phase I Environmental Site Assessment

use, store, and/or dispose of hazardous materials or hazardous wastes; (d) sites which have 

underground storage tanks (USTs); and (e) sites with recorded violations of regulations 

concerning USTs and hazardous materials/hazardous wastes. The database search is intended to 

identify facilities that may have the potential to impact surface and subsurface conditions on the 

Subject Property. A full listing of sites within the vicinity of the Subject Property is provided in 

Appendix D.

1.4.3 SITE RECONNIASSANCE 

Melissa Oberti and Trenton Wilson from AES conducted reconnaissance inspections of the 

Subject Property and adjacent properties on March 11 and October 8, 2009, respectively. The 

purpose of the site reconnaissance is to examine for obvious physical indications of improper 

hazardous substance or petrochemical disposal such as stained soil or asphalt, stressed vegetation, 

sumps, partially buried drums, bulk underground fuel storage tanks, and other obvious signs of 

hazardous materials involvement. In addition, adjacent properties were visually inspected to the 

extent possible without trespassing on private property to determine if current land uses would 

affect the planned uses of Subject Property. 

1.5 DEVIATIONS AND DATA GAPS 

ASTM Standard 1527-05 requires any significant data gaps, deviations and deletions from the 

ASTM Standard to be identified and commented on in the ESA. A significant data gap would be 

one that affected the ability to identify a REC on the Subject Property or adjacent properties. 

Due to the rural location of the Subject Property, Sanborn Fire Insurance maps were not available 

for the Subject Property. Because there is no historical data or physical indications that the 

property has ever been developed or occupied by a business that would have produced hazardous 

materials, the lack of Sanborn Fire Insurance maps is not considered a significant data gap for this 

Phase I ESA.

1.6 CREDENTIALS 

Melissa Oberti and Trenton Wilson prepared this report under the professional supervision of 

David Zweig, P.E., who qualifies as an environmental professional (EP) as defined in the ASTM 

Standard 1527-05 [40 CFR §312.10(b)]. The signatures of Melissa Oberti, Trenton Wilson, and 

David Zweig appear in Section 6.0 of this Phase I and their resumes are included as Appendix G.

SITE DESCRIPTION 

2.1 LOCATION AND LEGAL DESCRIPTION 

The Subject Property is located off Windsor River Road approximately 185 feet west of Pyne 

road, in unincorporated Sonoma County adjacent to the Town of Windsor, California (Figures 2 

and 3). The Sonoma County assessors’ parcel number (APN) for the Subject Property is 066-

191-019. 

2.2 SITE AND VICINITY CHARACTERISTICS

The Subject Property is comprised of 2.29 acres, half of which is developed with residential and 

associated residential landscaping/gardening areas and other associated structures. The southern 

half of the Subject Property consists of a barn and associated horse pasture. The topography of 

the Subject Property ranges in elevation from approximately 125 feet to 135 feet above mean sea 

level (amsl), increasing slightly in elevation from east to west and south to north. One relatively 

modern single-story single-family home, a single-car garage, workshop, five storage sheds, a 

horse barn with second floor apartment, and a chicken coup are located within the Subject 

Property’s boundaries. The residential and irrigation water demands are met by an on-site well 

with septic systems for wastewater treatment. 

Regional access is provided by US Highway 101 (US 101), which runs in a general south-north 

direction and is located 1.3 miles east of the Subject Property. Direct access to the Subject 

Property from US 101 is provided by Windsor River Road, which is a two-lane County road that 

traverses east for two miles from the Old Redwood Highway near US 101 to Eastside Road to the 

west of the Subject Property. The right-of-way for Windsor River Road adjoins the northern 

boundary of the Subject Property (Figure 3). 

2.3 LOCAL ENVIRONMENTAL RECORDS SOURCES 

Local Environmental Agency 

AES submitted a request for available files for review at the Sonoma County Environmental 

Health Department on October 13, 2009, regarding potential hazardous material incidents at the 

Subject Property. The Sonoma County Environmental Health Department had no records 

pertaining to the Subject Property.

website for listings of underground storage tanks (USTs), leaking underground storage tanks 

(LUSTs), or spill cases in association with petroleum chemicals at the Subject Property (SWRCB, 

2008). The Geotracker website had no listing of USTs, LUSTs, and spill cases at the Subject 

Property. The nearest listing is approximately 0.80 miles southwest of the Subject Property in 

response to an UST that was removed in 1991 showing signs of leakage. 

2.4 HYDROLOGY

One domestic well is located on the Subject Property. Based on the Department of Water 

Resources groundwater data (reference well located 0.25 miles west from the Subject Property), 

the depth to groundwater ranges from approximately 113 to 127 feet below ground surface (bgs) 

with a groundwater gradient generally towards the east towards the valley (DWR, 2009). 

Estimated groundwater levels and/or flow direction(s) may vary due to seasonal fluctuations in 

precipitation, local usage demands, geology, underground structures, or dewatering operations. 

From the northern half of the property, surface water drains primarily toward roadside drainages 

to the north. From the horse pasture, surface water primarily drains to a west to east flowing 

drainage that traverses the property. 

2.5 GEOLOGY AND SOIL

AES reviewed The EDR-Radius Map with Geocheck regulatory database report (EDR database 

report). According to information provided in the EDR database report, the rock stratigraphic 

unit at the Subject Property is Cenozoic, which is in the Quaternary system and series. Soils in 

the vicinity of the Subject Property include loam at depths ranging between zero and 14 inches 

below ground surface (bgs). Soils at depths ranging between 14 and 22 inches bgs are classified 

as sandy clay loam. Soils at depths ranging between 22 and 29 inches bgs are classified as clay. 

Soils at depths ranging between 29 and 57 inches bgs are classified as cemented. The hydrologic 

group rating for soils in this area is generally Class C, which indicates soils that exhibit slow 

water infiltration rates with soil layers impeding the downward movement of water.

2.6 CURRENT USES OF THE SUBJECT PROPERTY

Melissa Oberti and Trenton Wilson from AES performed site reconnaissance surveys of the 

Subject Property on March 11 and October 8th, 2009. No changes in land use were identified 

between the two surveys. The Subject Property is comprised of residential landscaped and paved 

areas with various residential gardens and orchards along the northern half of the property, with a 

horse barn (with second story apartment) and horse pasture along the southern half of the Subject 

Property. The Subject Property is developed with a single-family home and associated storage, 

agriculture, and horse rearing structures. Site photos showing conditions of the Subject Property 

during the site visit are shown in Figures 4 and 5 in Section 3.0. 

2.7 HISTORIC USES OF THE SUBJECT PROPERTY

2.7.1 AERIAL PHOTOGRAPHS

AES reviewed available historic aerial photographs (Appendix A) for information regarding past 

uses of the Subject Property and surrounding areas. The following aerial photographs were 

available for review: 1952 (1”=555’), 1965 (1”=333’), 1974 (1’=541’), 1982 (1”= 690’), 1993 

(1”= 666’), 1998 (1”= 666’),and 2005 (1”= 604’). Aerial photographs were of varying scale and 

clarity. Historical aerial images offer detailed review of previous land uses on the Subject 

Property and adjacent properties. 

1952 and 1965 

The Subject Property is undeveloped and appears to be used as an orchard. There is no 

distinction between the Subject Property and the adjacent property to the east. Windsor River 

Road is visible to the north of the Subject Property and Pyne Road is visible to the east of the 

adjacent property. The drainage traversing through the southern portion of the Subject Property 

is visible. The adjacent properties appear to be used for agriculture, with a former prisoner of war 

camp (Appendix D) clearly visible to the northwest of the Subject Property. To the south, a 

residence with various associated buildings is visible. In the 1965 aerial, the subject property 

appears the same as the 1952 aerial, while a residential housing unit has been developed on the 

adjacent property to the east. 

1974 and 1982 

The subject property is appears similar in the 1974 and 1982 aerial photos to the 1965 aerial 

photograph, with the adjacent residential unit to the east. Windsor River Road is visible to the 

north of the Subject Property and Pyne Road is visible to the east of the adjacent property. 

1993 and 1998 

The 1993 and 1998 aerial photos indicate development on the northern half of the Subject 

Property with residential and associated structures. Windsor River Road is visible to the north of 
2.0 Site Description

the Subject Property and Pyne Road is visible to the east of the adjacent property. Agriculture no 

longer appears to be the land use of the adjacent parcels. The horse barn is clearly visible in the 

1998 aerial photo. 

2005

The 2005 aerial photo is indicative of existing conditions. Windsor River Road is visible to the 

north of the Subject Property and Pyne Road is visible to the east of the adjacent property. The 

driveway of the residence appears consistent with existing conditions. The existing residence is 

visible in the center of the property as well are the storage structures around the property 

including the horse barn. The lower half of the Subject Property remains undeveloped and the 

drainage is visible traversing the property from west to east. 

2.7.2 HISTORIC TOPOGRAPHIC MAPS 

AES reviewed available historic USGS Topographic Quadrangles (Appendix B) for information 

regarding past uses of the Subject Property. The Healdsburg, California Topographic 

Quadrangle maps dated 1940, 1955, and 1993 were available for review. The 1940 and 1955 

topographic maps depict the Subject Property being undeveloped. No other features are 

presented on the Subject Property. The 1993 topographic map identifies the residence on the 

Subject Property. No other features are shown on the historical topographic maps of the region. 

2.8 SANBORN FIRE INSURANCE MAPS 

Sanborn Fire Insurance Maps do not provide coverage of the Subject Property. Documentation of 

the lack of coverage is included in Appendix C.

2.9 OTHER PHYSICAL SETTING SOURCES

SECTION 3.0 

SITE RECONNAISSANCE AND INTERVIEWS 

3.1 OBJECTIVE 

The objective of the site reconnaissance is to identify current or historic hazardous materials 

involvement on the Subject Property or in the vicinity of the Subject Property. Hazardous 

materials involvement or signature environmental conditions include the presence or likely 

presence of any hazardous materials or petroleum products that indicate an existing release, past 

release, or a threat of release into any structure on the property, soil, or groundwater. Signs of 

possible hazardous materials involvement would include any indications of underground storage 

tanks existing on the Subject Property, stained soils and/or unusual odors originating from the 

Subject Property, indications of an excavation or removal of soils, including patched asphalt and 

large debris piles, and other obvious signs of hazardous materials involvement. 

Interviews included contacting individuals familiar with the Subject Property and adjacent 

properties that are knowledgeable of historic and existing conditions relative to hazardous 

materials. 

3.2 SITE RECONNAISSANCE FINDINGS 

Melissa Oberti and Trenton Wilson from AES conducted site reconnaissance visits of the Subject 

Property on March 11 and October 8, 2009, respectively. Adjacent properties were observed to 

the extent possible without trespassing. Figures 4 and 5 provide photographs that show the site 

conditions at the time of the site visit. Notable features and environmental conditions are 

summarized below: 

x The Subject Property comprises approximately 2.29 acres of partially developed land. 

The northern half of the Subject Property is developed with a residential structure and 

associated storage facilities, a workshop, chicken coup, bee keeping facilities, landscaped 

areas, and residential agriculture (orchard, vineyard, and a garden). The southern half of 

the Subject Property consists of a horse barn with a second story apartment and 

associated horse pasture. A single-car garage is located on the Subject Property. The 

overall appearance of the Subject Property was consistent between the March and 

October site visit.

x A water well is located in the middle of the circular driveway at the center of the northern 

half of the Subject Property. The water well feeds two water well tanks located adjacent 

to the northwestern side of the residence. The condition of the water well was consistent 

between the two site visits. 

x An electricity service line extends from the transformer off the Subject Property along the 

right of way of Windsor River Road adjacent to the northwestern corner of the Subject 

Property (to power poles along the western boundary off the Subject Property. No 

transformers are located on the Subject Property. The condition of the electrical power 

lines was consistent between the two site visits. 

x The residential storage facilities contained bee keeping equipment and personal effects. 

x One of the storage facilities contained lawn and gardening equipment and a small fuel 

storage container (Photo 1). The fuel container appeared in good condition and no signs 

of leakage of the container or staining on the structures floor were observed during both 

site visits. 

x The workshop contained various lubricants, adhesives, and pesticides typically associated 

with a residential environment (Photo 2). The chemicals were stored within approved 

commercial containers and no surface staining or odor was observed inside or outside the 

workshop during both site visits. 

x The single-car garage contained various automobile cleaners that were stored in their 

original commercial containers. There were no signs of staining on the floor of the 

garage observed during both site visits. 

x The only change to the Subject Property observed between the two site visits was the 

progress of the remodeling of the barn. At the time of the October site visit, the horse 

barn (Photo 3) contained three additional horse stalls for a total of four stalls located 

along the eastern half of the first floor of the barn, with a small office at the northeastern 

corner of the barn. There were no indications of hazardous materials use in the stalls or 

within the office. The southeastern room of the barn has been converted into a wine 

making room (Photos 4 and 5). Although various pieces of wine making equipment 

were located within the room, there was no evidence of hazardous materials use. The 

second-story apartment (Photo 6) is accessed via a staircase from the inside of the barn 

near the wine room. The room housing the staircase is currently being renovated. The 

upstairs apartment has been renovated since the March site visit to include a great room 

with a plumbed kitchen area, one bedroom, and a plumbed bathroom. No signs of 

hazardous materials were present within the apartment. Adjacent to the barn along the 

southern exterior is a solar array that was observed during both site visits.

x The horse pasture appears consistent between the two site visits with the drainage 

tributary visible along the southern portion of the pasture. 

3.3 ADJACENT PROPERTIES 

AES performed a survey of adjacent properties to the extent possible without trespassing. The 

purpose was to identify adjacent businesses and determine if current land uses would affect the 

planned use of the Subject Property. Adjacent land uses are described below. 

x North: Windsor River Road is located to the north. A power line with a pole mounted 

transformer was observed along the Windsor Creek Roadway right-of-way adjacent to 

the northwestern corner of the property boundary. No leaks associated with the 

transformers were observed. Across Windsor River Road north of the Subject Property 

are agricultural lands with residential development located to the northwest and northeast. 

x South: A residence and associated agricultural structures are located south of the Subject 

Property. The property south of the residence appears to be used for grazing. 

x East and West: Private residences with grazing lands adjoin the Subject Property to the 

east and west. The size, layout, and land uses of the adjoining properties are consistent 

with the Subject Property.

RECORDS REVIEW 

4.1 DATABASE SEARCH

Database searches were conducted for records of known storage tank sites and known sites of 

hazardous materials generation, storage, and/or contamination. Databases were searched for sites 

and listings up to one mile from the Subject Property. The environmental database review was 

accomplished by using the services of a computerized search firm Environmental Data 

Resources, Inc. (EDR). EDR uses a geographical information system to plot locations of past or 

previous hazardous materials involvement. AES reviewed the EDR report to determine if the 

Subject Property and adjacent sites are listed on regulatory agency databases. The purpose is to 

determine if adjacent sites will impact surface and/or subsurface conditions on the Subject 

Property. Included in the EDR database report was a list of “unmapped sites”. AES reviewed the 

list of unmapped sites for the properties that may be located within the search radius specified for 

each governmental database. These sites do not appear to be located within the applicable search 

radius of the Subject Property. The complete list of reviewed databases is provided in the EDR 

report, included in Appendix D and is summarized in Table 4-1. Information on past and/or 

current hazardous materials involvement involving adjacent properties is summarized in Section 

4.2.2. 

4.2 HAZARDOUS MATERIALS INVOLVEMENT 

A regulatory agency database report was performed to identify locations of past and/or current 

hazardous materials involvement. Regulatory agency databases were searched for records of 

known storage tank sites and known sites of hazardous materials generation, storage, or 

contamination, or where violations pertaining to storage and/or use of hazardous materials have 

occurred. Databases were searched for sites and listings up to one mile from a point roughly 

equivalent to the center of Subject Property. Although a site may be listed within the database 

report, this does not mean the site is currently contaminated or will impact the environmental 

quality of the Subject Property. It should be noted that the database search is only as accurate as 

the data entered into the government agency maintained databases and the date on which those 

databases were last updated. Installation of underground storage tanks or hazardous material 

releases, if not reported to the appropriate agency, would not be listed on any of the databases 

searched.

Analytical Environmental Services 4-4 Lytton 2.29-Acres 

207513 Phase I Environmental Site Assessment

4.2.2 ADJACENT PROPERTIES

Three sites were identified within one mile of the Subject Property. One site was listed as a 

former United States Army defense site, one site was listed on multiple databases for known 

contamination or for which there may be reasons to investigate further, and one site was listed 

three times regarding Proposition 65 notices for potential impacts to drinking water. 

The Windsor Prisoner of War Labor Camp (Labor Camp) (Appendix D) is located approximately 

0.20 miles northwest of the Subject Property and is listed on the FUDS database. The Labor 

Camp once comprised 66.74 acres approximately 1 mile west of the Town of Windsor, 6 miles 

south of Healdsburg. The site was relinquished to an unknown party in 1946 and then 

retransferred to the United States Department of Agriculture. Currently, three of the former 

bunkhouses are used as residences and open space is used for pastures. According to the 

database, no potential hazards related to Department of Defense activity have been located on the 

66.74 acre site. Based on the current regulatory status and lack of violations reported, this site is 

not likely to pose a risk to the environmental quality of the Subject Property. 

Windsor Fuel is located 1.00 mile northeast of the Subject Property adjacent to US 101 on the 

Old Redwood Highway. Windsor Fuel is a fuel distributor listed on the CERCLIS, FINDS, 

LUST, SLIC, and ENVIROSTOR databases. Windsor Fuel is also listed as operating under an 

National Pollution Discharge Elimination System (Clean Water Act Section 402) permit for 

industrial storm water discharge. The site is listed in response to the removal of several 

underground storage tanks and the identification of soil and groundwater contamination with 

heavy weight petroleum hydrocarbons. The extent of the contamination has been defined and the 

plume does not appear to be migrating. The listing status is currently open and verification 

monitoring is being performed. Based on the current regulatory status of a confined, nonmigrating plume, distance from the project site, and lack of additional violations reported, this 

site is not likely to pose a risk to the environmental quality of the Subject Property. 

The facility at 340 Windsor River Road located 0.95 miles east of the Subject Property is listed as 

requiring a Proposition 65 notice to the surrounding community regarding a release that has the 

potential to impact drinking water supplies. Although there are three listings for the site, the date 

of report (October 16, 1992), incident description number, and Board file number are identical 

between the three listings. The incident is reported as a leak; however, no other information is 

given. Based on the lack of additional listings in other governmental agency databases indicating 

no further action required and distance from the project site, this site is not likely to pose a risk to 

the environmental quality of the Subject Property.

SECTION 5.0 

FINDINGS AND CONCLUSIONS 

This Phase I ESA was performed in conformance with the scope and limitations of ASTM 

Standard Practice E1527-05 and BIA guidelines (602 DM Chapter 2). Based on information 

gathered while conducting this Phase I ESA, AES observed the following environmental 

conditions:

x The 2.29-acre Subject Property consists of residential and associated residential 

landscaping/gardening areas and other associated structures on the northern half of the 

property. The southern half of the Subject Property consists of a barn and associated 

horse pasture. The earliest available historic aerial photographs from EDR show that the 

Subject Property was developed with orchards in 1952, with the development of 

residential structures being shown in 1993. 

x Several electric transformers attached to power poles are located adjacent to the Subject 

Property. No leaks were observed. 

x The residential storage sheds contained various chemicals, pesticides, and 

gardening/landscaping chemicals that were stored within approved commercial 

containers and no surface staining or odor was observed inside or outside the shed. 

There are no RECs associated with the numerous storage sheds located on the Subject 

Property. 

x The horse barn and associated solar array are in good condition and do not contain RECs. 

AES has performed a Phase I ESA in conformance with the scope and limitations of ASTM 

Practice E 1527 of 1332 Windsor River Road, the Subject Property. Any exceptions to, or 

deletions from, this practice are described in Section 1.0 of this report. This assessment has 

revealed no evidence of RECs in connection with the Subject Property.

207513 Phase I Environmental Site Assessment

SECTION 1.0

INTRODUCTION

1.1 PURPOSE 

Analytical Environmental Services (AES) has prepared this Environmental Site Assessment 

(ESA) in conformance with the Bureau of Indian Affairs (BIA) guidelines (602 DM Chapter 2) 

and the American Society for Testing and Materials (ASTM) Standard Practice E 1527-05, which 

specifies the appropriate inquiry requirement for the innocent landowner defense under the 

Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). This 

ESA encompasses two legal parcels of approximately 6.0 acres, located in the County of Sonoma, 

California (Figure 1). As such, the use of the term “Subject Property” refers to the entire 6.0-

acre property unless otherwise stated. The purpose of this assessment is to identify Recognized 

Environmental Conditions (RECs) that may affect future uses of the Subject Property. 

This ESA covers the Subject Property, adjacent areas, and surrounding known sources of 

contamination, up to 1.0 mile from the Subject Property. A site reconnaissance inspection of the 

Subject Property and adjacent properties was performed and relevant database listings of 

hazardous materials sites, waste generators, and underground storage tanks were reviewed (EDR, 

2009). AES also reviewed historical aerial photographs for the Subject Property. Years available 

for review were 1952, 1965, 1973, 1982, 1993, 1998, and 2005. 

1.2 RECOGNIZED ENVIRONMENTAL CONDITIONS 

The term REC refers to the presence or likely presence of any hazardous substances or petroleum 

products on a property under conditions that indicate an existing release, a past release, or a 

material threat of release of any hazardous substances or petroleum products into structures on the 

property or into the ground, groundwater, or surface water of the property. The term includes 

hazardous substances or petroleum products even under conditions in compliance with laws. The 

term is not intended to include de minimis conditions that generally do not present a material risk 

of harm to public health or the environment and that generally would not be the subject of an 

enforcement action if brought to the attention of appropriate governmental agencies. 

Additionally, the term historical REC refers to an environmental condition associated with the 
Lytton 6.0-Acre Phase I ESA / 207513

Analytical Environmental Services 1-3 Lytton 6.0-Acres 

207513 Phase I Environmental Site Assessment

Subject Property, including a past release of any hazardous substance or petroleum product, 

which in the past would have been considered a REC, however such condition has since been 

remediated. Historical RECs will therefore be included in this Phase I ESA (ASTM, 2006). 

1.3 LIMITATIONS AND EXCEPTIONS 

No ESA can completely eliminate uncertainty regarding the potential for RECs in connection 

with a property. Conformance of this assessment with ASTM Standard Practice E 1527-05 will 

reduce, but not eliminate, uncertainty regarding the potential for RECs in connection with the 

Subject Property. While AES has made every effort to discover and interpret available historical 

and current information on the property within the time available, the possibility for undiscovered 

contamination to be present remains. AES’s report is a best-effort collection and interpretation of 

available information consistent with industry standards for the completion of Phase I ESAs. 

This ESA is based on a site reconnaissance of the Subject Property, searches of government 

hazardous materials databases, and interviews with individuals familiar with the historical uses of 

the Subject Property. Physical testing of soil or groundwater was not within the scope of this 

assessment. Asbestos containing building materials (ACM) and lead-based paint surveys were 

not included. Information was obtained for this ESA to comply with ASTM guidelines. 

1.4 METHODOLOGY 

A variety of data sources were consulted in completing this Phase I ESA. The following subsections describe the methods used and the data sources consulted to accomplish each task.

1.4.1 HISTORICAL REVIEW 

Previous land uses and history of the Subject Property were researched in an effort to identify 

RECs at or near the Subject Property. Historical aerial photographs (Appendix A) and

topographic maps (Appendix B) from different decades were examined for the presence of 

aboveground storage tanks, industrial buildings, gas station canopies and/or pump islands, as well 

as other indications of bulk hazardous material storage within the study area. Sanborn Fire 

Insurance Maps (Appendix C) document historical property use through abbreviations and map 

symbols that identify commercial, industrial, residential and other land uses. 

1.4.2 DATABASE SEARCHES 

Database searches were conducted for records of known storage tank sites and known sites of 

hazardous materials generation, storage, or release. Available information from federal, state, 

and local agency lists of: (a) known or potential hazardous waste sites and landfills; (b) sites 

currently under investigation for environmental violations; (c) sites which manufacture, generate, 
1.0 Introduction 

 

Analytical Environmental Services 1-4 Lytton 6.0-Acres 

207513 Phase I Environmental Site Assessment

use, store, and/or dispose of hazardous materials or hazardous wastes; (d) sites which have 

underground storage tanks (USTs); and (e) sites with recorded violations of regulations 

concerning USTs and hazardous materials/hazardous wastes. The database search is intended to 

identify facilities that may have the potential to impact surface and subsurface conditions on the 

Subject Property. A full listing of sites within the vicinity of the Subject Property is provided in 

Appendix D.

1.4.3 SITE RECONNIASSANCE 

Melissa Oberti from AES conducted a reconnaissance inspection of the Subject Property and 

adjacent properties on February 2, 2010. The purpose of the site reconnaissance is to examine the 

property for obvious physical indications of improper hazardous substance or petrochemical 

disposal such as stained soil or asphalt, stressed vegetation, sumps, partially buried drums, bulk 

underground fuel storage tanks, and other obvious signs of hazardous materials involvement. In 

addition, adjacent properties were visually inspected to the extent possible without trespassing on 

private property to determine if current land uses would affect the planned uses of Subject 

Property. 

1.5 DEVIATIONS AND DATA GAPS 

ASTM Standard 1527-05 requires any significant data gaps, deviations and deletions from the 

ASTM Standard to be identified and commented on in the Phase I. A significant data gap would 

be one that affected the ability to identify a REC on the Subject Property or adjacent properties. 

Due to the rural location of the Subject Property, Sanborn Fire Insurance maps were not available 

for the Subject Property. Because there is no historical data or physical indications that the 

property has ever been developed or occupied by a business that would have produced hazardous 

materials, the lack of Sanborn Fire Insurance maps is not considered a significant data gap for this 

Phase I ESA.

1.6 CREDENTIALS 

Melissa Oberti prepared this report under the professional supervision of David Zweig, P.E., who 

qualifies as an environmental professional (EP) as defined in the ASTM Standard 1527-05 [40 

CFR §312.10(b)]. The signatures of Melissa Oberti and David Zweig appear in Section 6.0 of 

this Phase I and their resumes are included as Appendix G.

SITE DESCRIPTION
Analytical Environmental Services 2-1 Lytton 6.0-Acres 

207513 Phase I Environmental Site Assessment

SECTION 2.0 

SITE DESCRIPTION 

2.1 LOCATION AND LEGAL DESCRIPTION 

The Subject Property is located near the intersection of Windsor River Road and River Oaks 

Lane, in unincorporated Sonoma County just west of the Town of Windsor, California (Figures 2 

and 3). The Sonoma County assessors’ parcel numbers (APN) for the Subject Property are 066-

300-017 (4.79-acres) and 066-300-023 (1.21-acres). 

2.2 SITE AND VICINITY CHARACTERISTICS

The Subject Property is comprised of a total of 6.0 acres, the majority of which is developed with 

two residences and associated storage structures. Approximately one acre of the Subject Property 

(northwest section adjacent to Windsor River Road) consists of vineyards. The topography of the 

Subject Property ranges in elevation from approximately 140 feet to 145 feet above mean sea 

level (amsl). One relatively modern single-story single-family home, a single-story studio, a twocar garage, two aged water treatment structures, one aged storage shed, and one aged barn are 

located within the Subject Property’s boundaries. The residential and irrigation water demands 

are met by an on-site well with septic systems for wastewater treatment. 

Regional access is provided by US Highway 101 (US 101), which runs in a general south-north 

direction and is located 1.3 miles east of the Subject Property. Local access to the Subject 

Property from US 101 is provided by Windsor River Road, which is a two-lane County road that 

traverses east for two miles from the Old Redwood Highway near US 101 to Eastside Road to the 

west of the Subject Property. The right-of-way for Windsor River Road adjoins the northern 

boundary of parcel 066-300-017. Direct access to the Subject Property is off Windsor River 

Road (Figure 3). 

2.3 LOCAL ENVIRONMENTAL RECORDS SOURCES 

Local Environmental Agency 

AES submitted a request for available files for review at the Sonoma County Environmental 

Health Department on February 5, 2010 regarding potential hazardous material incidents at the 

Subject Property. The Sonoma County Environmental Health Department had no records 

pertaining to the Subject Property.

Department of Planning and Zoning 

AES reviewed the Sonoma County Planning Department website (http://www.sonomacounty.org/prmd/docs/zoning/index.htm) for the zoning of the Subject Property. The Subject 

Property is zoned AR (Agriculture and Residential District), which is consistent with the current 

location and land use. 

Electrical Utility Company 

AES spoke with a representative of the owners on February 2, 2010 who confirmed that PG&E 

provides electrical and gas utilities to the Subject Property. 

Other Local Environmental Records Sources 

AES reviewed the California Regional Water Quality Control Board’s (CRWQCB) Geotracker 

website for listings of underground storage tanks (USTs), leaking underground storage tanks 

(LUSTs), or spill cases in association with petroleum chemicals at the Subject Property (SWRCB, 

2008). The Geotracker website had no listing of USTs, LUSTs, and spill cases at the Subject 

Property. The nearest listing is approximately 0.94 miles southwest of the Subject Property in 

response to an UST that was removed in 1991 showing signs of leakage. 

2.4 HYDROLOGY

One domestic well is located on the Subject Property. Based on the Department of Water 

Resources groundwater data (reference well located 0.1 miles north from the Subject Property), 

the depth to groundwater ranges from approximately 113 to 127 feet below ground surface (bgs) 

with a groundwater gradient generally towards the east (DWR, 2010). Estimated groundwater 

levels and/or flow direction(s) may vary due to seasonal fluctuations in precipitation, local usage 

demands, geology, underground structures, or dewatering operations. From the vineyard, surface 

water drains primarily toward roadside drainages to the north. From the house and surrounding 

area, surface water primarily drains to the east to an ephemeral drainage through a culvert then 

into roadside drainage that flows west to east. 

2.5 GEOLOGY AND SOIL

AES reviewed The EDR-Radius Map with Geocheck regulatory database report (EDR database 

report). According to information provided in the EDR database report, the rock stratigraphic 

unit at the Subject Property is Cenozoic, which is in the Quaternary system and series. Soils in 

the vicinity of the Subject Property include loam at depths ranging between zero and nine inches 

below ground surface (bgs). Soils at depths ranging between nine and 18 inches bgs are 

classified as clay loam. Soils at depths ranging between 18 and 37 inches bgs are classified as 

clay. Soils at depths ranging between 37 and 59 inches bgs are classified as cemented. The 

hydrologic group rating for soils in this area is generally Class C, which indicates soils that 

exhibit slow water infiltration rates with soil layers impeding the downward movement of water. 
2.0 Site Description 

Analytical Environmental Services 2-5 Lytton 6.0-Acres 

207513 Phase I Environmental Site Assessment

2.6 CURRENT USES OF THE SUBJECT PROPERTY

Melissa Oberti from AES performed a site reconnaissance survey of the Subject Property on 

February 2, 2010. The Subject Property is comprised of a small vineyard along the northwestern 

portion of the property with the remainder of the property consisting of residential landscaped, 

gravel areas and undeveloped oak woodland. The Subject Property is developed with a singlefamily home, a single-story studio and associated storage structures. Site photos showing 

conditions of the Subject Property during the site visit are shown in Figure 4 in Section 3.0. 

2.7 HISTORIC USES OF THE SUBJECT PROPERTY

2.7.1 AERIAL PHOTOGRAPHS

AES reviewed available historic aerial photographs (Appendix A) for information regarding past 

uses of the Subject Property and surrounding areas. The following aerial photographs were 

available for review: 1952 (1”=555’), 1965 (1”=333’), 1973 (1’=555’), 1982 (1”= 690’), 1993 

(1”= 666’), 1998 (1”= 666’), and 2005 (1”= 604’). Aerial photographs were of varying scale and 

clarity. Historical aerial images offer detailed review of previous land uses on the Subject 

Property and adjacent properties. 

1952 and 1965 

The Subject Property is undeveloped with oak woodland. Two structures are visible directly to 

the north beyond which is Windsor River Road. Various other trees are shown on the Subject 

Property that do not currently exist. The adjacent properties to the north appear to be used for 

agriculture, with a former prisoner of war camp (Appendix D) clearly visible to the northeast of 

the Subject Property. Further details on this camp are provided in Section 4.2.2. The adjacent 

properties to the south, east and west appear to be undeveloped with oak woodland. 

1973 and 1982 

The Subject Property appears to be developed with two structures. The 1982 aerial photograph 

does not clearly depict the Subject Property due to poor resolution in the photograph; however 

conditions appear to be consistent with the 1973 aerial photograph. The vineyard is not visible on 

the aerials photographs. Two structures are visible directly north of the Subject Property. 

Windsor River Road is visible to the north beyond which are several structures. The adjacent 

properties to the south, east and west appear to be undeveloped with oak woodland. 

1993 and 1998 

The 1993 and 1998 aerial photos indicate uses of the western portion of the Subject Property 

remain consistent with the residential use observed in the 1973 and 1982 aerial photographs. The 

vineyard is not visible on the aerials photographs. Two structures are visible directly to the north. 
2.0 Site Description 

Analytical Environmental Services 2-6 Lytton 6.0-Acres

Windsor River Road is visible to the north beyond which are several structures. The adjacent 

properties to the south, east and west appear to be undeveloped with oak woodland. 

2005

The 2005 aerial photograph shows the Subject Property developed in its current configuration. 

The residential portion of property appears consistent with existing conditions and the existing 

barn is visible in the center of the property. Two structures are visible directly to the north. 

Windsor River Road is visible to the north beyond which are several structures. The adjacent 

properties to the south and west appear to be undeveloped oak woodland. Several structures are 

visible to the east of the Subject Property. 

2.7.2 HISTORIC TOPOGRAPHIC MAPS 

AES reviewed available historic USGS Topographic Quadrangles (Appendix B) for information 

regarding past uses of the Subject Property. The Healdsburg, California Topographic 

Quadrangle maps dated 1940, 1955, and 1993 were available for review. The 1940 and 1955 

topographic maps depict the Subject Property as being undeveloped. No other features are 

presented on the Subject Property. The 1993 topographic map depicts the residence and an 

additional structure on the Subject Property. The 1993 topographic map does not identify the 

vineyards on the Subject Property and indicates several structures north on adjacent properties. 

2.8 SANBORN FIRE INSURANCE MAPS 

Sanborn Fire Insurance Maps do not provide coverage of the Subject Property. Documentation of 

the lack of coverage is included in Appendix C.

2.9 OTHER PHYSICAL SETTING SOURCES 

Wetlands Map 

According to the Overview Map located with the regulatory database report, which references 

information provided by the National Wetlands Inventory (NWI) Map for the Healdsburg NWI 

Quad, no wetlands are located on the property. A copy of the Overview Map is included in the 

regulatory database report in Appendix D. 

Floodplain Map 

According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map 

(FIRM) number 06097C0562E (effective December 2, 2008), the Subject Property is located in 

Flood Zone X. Zone X is identified by FEMA as areas located outside the 0.2 percent annual 

chance floodplain. A copy of the floodplain map is included in Appendix E.

SECTION 3.0 

SITE RECONNAISSANCE AND INTERVIEWS 

3.1 OBJECTIVE 

The objective of the site reconnaissance is to identify current or historic hazardous materials 

involvement on the Subject Property or in the vicinity of the Subject Property. Hazardous 

materials involvement or signature environmental conditions include the presence or likely 

presence of any hazardous materials or petroleum products that indicate an existing release, past 

release, or a threat of release into any structure on the property, soil, or groundwater. Signs of 

possible hazardous materials involvement would include any indications of underground storage 

tanks existing on the Subject Property, stained soils and/or unusual odors originating from the 

Subject Property, indications of an excavation or removal of soils, including patched asphalt and 

large debris piles, and other obvious signs of hazardous materials involvement. 

Interviews included contacting individuals familiar with the Subject Property and adjacent 

properties that are knowledgeable of historic and existing conditions relative to hazardous 

materials. 

3.2 SITE RECONNAISSANCE FINDINGS 

Melissa Oberti from AES conducted a site reconnaissance of the Subject Property on February 2, 

2010. Adjacent properties were observed to the extent possible without trespassing. Figure 4 

provides photographs that show the site conditions at the time of the site visit. Notable features 

and environmental conditions are summarized below: 

x The Subject Property comprises approximately 6.0 acres of partially developed land 

(Photo 1). The northwestern portion of the Subject Property is planted with vineyards 

(Photo 2). The remainder of the Subject Property consists of a single-story residence, 

two-car garage, an additional residential unit, barn, and three storage structures.

RECORDS REVIEW 

4.1 DATABASE SEARCH

Database searches were conducted for records of known storage tank sites and known sites of 

hazardous materials generation, storage, and/or contamination. Databases were searched for sites 

and listings up to one mile from the Subject Property. The environmental database review was 

accomplished by using the services of a computerized search firm Environmental Data 

Resources, Inc. (EDR). EDR uses a geographical information system to plot locations of past or 

previous hazardous materials involvement. AES reviewed the EDR report to determine if the 

Subject Property and adjacent sites are listed on regulatory agency databases. The purpose is to 

determine if adjacent sites will impact surface and/or subsurface conditions on the Subject 

Property. Included in the EDR database report was a list of “unmapped sites”. AES reviewed the 

list of unmapped sites for the properties that may be located within the search radius specified for 

each governmental database. These sites do not appear to be located within the applicable search 

radius of the Subject Property. The complete list of reviewed databases is provided in the EDR 

report, included in Appendix D and is summarized in Table 4-1. Information on past and/or 

current hazardous materials involvement involving adjacent properties is summarized in Section 

4.2.2. 

4.2 HAZARDOUS MATERIALS INVOLVEMENT 

A regulatory agency database report was performed to identify locations of past and/or current 

hazardous materials involvement. Regulatory agency databases were searched for records of 

known storage tank sites and known sites of hazardous materials generation, storage, or 

contamination, or where violations pertaining to storage and/or use of hazardous materials have 

occurred. Databases were searched for sites and listings up to one mile from a point roughly 

equivalent to the center of Subject Property. Although a site may be listed within the database 

report, this does not mean the site is currently contaminated or will impact the environmental 

quality of the Subject Property. It should be noted that the database search is only as accurate as 

the data entered into the government agency maintained databases and the date on which those 

databases were last updated. Installation of underground storage tanks or hazardous material 

releases, if not reported to the appropriate agency, would not be listed on any of the databases 

searched.

207513 Phase I Environmental Site Assessment

4.2.2 ADJACENT PROPERTIES

One site was identified within one mile of the Subject Property: 

The Windsor Prisoner of War Labor Camp (Labor Camp) (Appendix D) is located approximately 

0.27 miles north of the Subject Property and is listed on the FUDS database. The Labor Camp 

once comprised 66.74 acres approximately 1 mile west of the Town of Windsor, 6 miles south of 

Healdsburg. The site was relinquished to an unknown party in 1946 and then retransferred to the 

United States Department of Agriculture. Currently, three of the former bunkhouses are used as 

residences and open space is used for pastures. According to the database, no potential hazards 

related to Department of Defense activity have been located on the 66.74 acre site. Based on the 

current regulatory status and lack of violations reported, this site is not likely to pose a risk to the 

environmental quality of the Subject Property.

FINDINGS AND CONCLUSIONS
Analytical Environmental Services 5-1 Lytton 6.0-Acres 

207513 Phase I Environmental Site Assessment

SECTION 5.0 

FINDINGS AND CONCLUSIONS 

This Phase I ESA was performed in conformance with the scope and limitations of ASTM 

Standard Practice E1527-05 and BIA guidelines (602 DM Chapter 2). Based on information 

gathered while conducting this Phase I ESA, AES observed the following environmental 

conditions:

x The 6.0-acre Subject Property is comprised of a vineyards, an occupied private residence, 

an additional private residence, associated water treatment structures, one single-story 

storage structure, single-story barn, and a two-car garage. The earliest available historic 

aerial photographs from EDR show that the Subject Property was undeveloped with oak 

woodland in 1952. 

x One electric transformer attached to a power pole is located on the Subject Property. 

Several electric transformers attached to power poles are located adjacent to the Subject 

Property. No leaks were observed. 

x The storage shed contained various chemicals including pesticides, paint, gasoline, and 

gardening/landscaping chemicals that were stored within approved commercial 

containers. No surface staining or odor was observed inside or outside the shed. 

x The barn contained a tractor, various tools used for wine making, and a wine cellar 

containing barrels of wine. 

AES has performed this Phase I ESA in conformance with the scope and limitations of ASTM 

Practice E 1527. Any exceptions to, or deletions from, this practice are described in Section 1.0

of this report. This assessment has revealed no evidence of RECs in connection with the Subject 

Property. Based on the findings and conclusions of this Phase I ESA, the listed environmental 

conditions above do not warrant any further study.

EXECUTIVE SUMMARY

TC2690032.2s EXECUTIVE SUMMARY 5

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on

a relative (not an absolute) basis. Relative elevation information between sites of close proximity

should be field verified. Sites with an elevation equal to or higher than the target property have been

differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed

data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

Archived sites are sites that have been removed and archived from the inventory of CERCLIS sites. Archived status

indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined

no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates

this decision was not appropriate or other considerations require a recommendation for listing at a later time.

This decision does not necessarily mean that there is no hazard associated with a given site; it only means that,

based upon available information, the location is not judged to be a potential NPL site.

US BROWNFIELDS: A Listing of Brownfields Sites

Included in the listing are brownfields properties addresses by Cooperative Agreement Recipients and brownfields

properties addressed by Targeted Brownfields Assessments. Targeted Brownfields Assessments-EPA’s Targeted Brownfields

Assessments (TBA) program is designed to help states, tribes, and municipalities--especially those without EPA

Brownfields Assessment Demonstration Pilots--minimize the uncertainties of contamination often associated with

brownfields. Under the TBA program, EPA provides funding and/or technical assistance for environmental assessments

at brownfields sites throughout the country. Targeted Brownfields Assessments supplement and work with other efforts

under EPA’s Brownfields Initiative to promote cleanup and redevelopment of brownfields. Cooperative Agreement

Recipients-States, political subdivisions, territories, and Indian tribes become Brownfields Cleanup Revolving

Loan Fund (BCRLF) cooperative agreement recipients when they enter into BCRLF cooperative agreements with the

U.S. EPA. EPA selects BCRLF cooperative agreement recipients based on a proposal and application process. BCRLF

cooperative agreement recipients must use EPA funds provided through BCRLF cooperative agreement for specified

brownfields-related cleanup activities.

UMTRA: Uranium Mill Tailings Sites

Uranium ore was mined by private companies for federal government use in national defense programs. When the mills

shut down, large piles of the sand-like material (mill tailings) remain after uranium has been extracted from

the ore. Levels of human exposure to radioactive materials from the piles are low; however, in some cases tailings

were used as construction materials before the potential health hazards of the tailings were recognized.

EDR PROPRIETARY RECORDS

EDR Proprietary Records

Manufactured Gas Plants: EDR Proprietary Manufactured Gas Plants

The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)

compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s

to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture

of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,

such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds

are potentially hazardous to human health and the environment. The byproduct from this process was frequently

disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil

and groundwater contamination.

Water Quality Assessment, Lathrop, California. Under contract to the US 

Army Corps of Engineers, prepared an ERWQA for the depot's wastewater 

treatment plant effluent discharge. Effluent is treated at a secondary facility onsite, and discharged into an irrigation ditch that is tributary to French Camp 

Slough. Water quality concerns associated with the implementation of the Inland 

Surface Water Plan prompted the Regional Water Quality Control Board to 

require an ERWQA as a condition in the plant's Waste Discharge Requirements. 

Based on a limited number of lab tests, a work plan was prepared for the ERWQA 

to assess the impact of continued effluent discharges on the receiving water and 

possibly lead to treatment process and/or operational modifications.

 Sacramento Municipal Utilities District Phase I and II Environmental 

Assessments. Performed Phase I and Phase II environmental site assessments on 

two cogeneration plant sites. The assessments consisted of records searches, 

interviews with representatives from regulatory agencies, field reconnaissance, 

sampling of surface soils, laboratory testing, and analysis of data. The 

assessments resulted in recommendations regarding the need for additional 

subsurface investigations and the risks associated with disposing of soil from the 

sites. 

 City of Willits Sanitary Survey, Mendocino County. Managed the preparation 

of a watershed sanitary survey for the City Water Department for submission to 

the Department of Health Services to comply with the California Surface Water 

Treatment Regulation. In accordance with AWWA guidelines, the survey 

identifies potential contaminant sources within the watershed, and suggests 

methods for effectively managing the watershed. Potential contaminant sources 

within the 3,200-acre watershed include septic systems, mining, and a police 

shooting range. 

 Carmichael Water District Bajamont Way Phase I Environmental Site 

Assessment and Disposal Area Preliminary Assessment. Performed a Phase 1 

environmental assessment on the District's Corporation Yard site. The assessment 

consisted of a records search, interviews with representatives from regulatory 

agencies, field reconnaissance, sampling of surface soils, laboratory testing, and 

analysis of data. The assessment resulted in recommendations regarding the need 

for additional subsurface investigations and the risks associated with disposing of 

soil from the site. A preliminary assessment of a spoils disposal area at the site 

was also performed. 

 City of San Leandro Groundwater Monitoring Program. Developed and 

implemented a groundwater monitoring program for the City's Dredged Material 

Management Site, adjacent to San Francisco Bay. The site is used to dewater 

dredged material from the City's marina prior to land disposal. As a condition of 

the City's NPDES permit, ESA developed and implemented a groundwater 

investigation that included the installation and quarterly sampling of six 

monitoring wells. Four quarterly reports were prepared and submitted to the 

Regional Water Quality Control Board.

 Auto Park Treatment Tank Relocation Engineering, Environmental Review, 

and Land Acquisition. Relocated Calgon activated carbon adsorption system, 

consisting of two tanks each with 20,000 pounds of granular activated carbon. 

Project included installing water and sewer pipelines, booster pump station, and 

electronic controls, so as to allow continued use of a 1,000+ gpm well. The 

treatment system had been temporarily sited as an emergency measure to treat 

PCE contamination discovered in water from an existing well. Community 

concerns about visual impacts necessitated relocation.

 Strasbaugh Well Nitrate Treatment Engineering Studies. Studied the 

feasibility of providing nitrate removal for a contaminated groundwater source. 

Proven groundwater supplies were unusable because of nitrate contamination in 

the area. The contamination was the result of decades of intensive agricultural 

activity. An ion exchange process designed to remove nitrates from well water, 

and supporting infrastructure, was evaluated. 

 American I Cogeneration Facility Spill Prevention Control and 

Countermeasure Plan. In cooperation with Sage Environmental, prepared a 

SPCCP for a cogeneration facility in King City. The American I facility uses a 

gas turbine cogeneration unit to generate electricity and provide steam and hot 

water to a neighboring food processing plant. Because of the large quantities of 

fuels and other chemicals stored at the facility, a SPCCP was required by the 

Regional Water Quality Control Board (RWQCB). In requiring the SPCCP, the 

RWQCB was implementing the regulations contained in Title 40 of the Code of 

Federal Regulations, Part 112. The SPCCP consists of an inventory of storage 

tanks and containment systems at the facility and recommendations to prevent 

hazardous materials from being released into nearby surface waters. 

 Defense Distribution Region West Sharpe Depot Storm Water Pollution 

Prevention Plan, Lathrop, California. Under contract to the US Army Corps of 

Engineers, prepared a SWPPP for the 300 acre Sharpe Depot. The depot receives, 

warehouses, and ships out military supplies and equipment. Shipments of bulk 

chemicals, mechanical parts, weapons, ammunition, and supplies arrive at the 

depot by air, rail, and truck. Previous spills at the depot have caused groundwater 

contamination and required remedial actions. To comply with Regional Water 

Quality Control Board NPDES permit requirements, a SWPPP was prepared that 

inventoried possible sources of stormwater pollution, and recommended measures 

to prevent those pollutants from entering storm water.

SECTION 1.0

INTRODUCTION

1.1 PURPOSE 

Analytical Environmental Services (AES) has prepared this Environmental Site Assessment 

(ESA) in conformance with the Bureau of Indian Affairs (BIA) guidelines (602 DM Chapter 2) 

and the American Society for Testing and Materials (ASTM) Standard Practice E 1527-05, which 

specifies the appropriate inquiry requirement for the innocent landowner defense under the 

Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). This 

ESA encompasses one legal parcel of approximately 4.11 acres, located in the County of 

Sonoma, California (Figure 1). As such, the use of the term “Subject Property” refers to the 

entire 4.11-acre property unless otherwise stated. The purpose of this assessment is to identify 

Recognized Environmental Conditions (RECs) that may affect future uses of the Subject 

Property. 

This ESA covers the Subject Property, adjacent areas, and surrounding known sources of 

contamination, up to 1.0 mile from the Subject Property. A site reconnaissance inspection of the 

Subject Property and adjacent properties was performed and relevant database listings of 

hazardous materials sites, waste generators, and underground storage tanks were reviewed (EDR, 

2010). AES also reviewed historical aerial photographs for the Subject Property. Years available 

for review were 1952, 1965, 1974, 1982, 1993, 1998, and 2005. 

1.2 RECOGNIZED ENVIRONMENTAL CONDITIONS 

The term REC refers to the presence or likely presence of any hazardous substances or petroleum 

products on a property under conditions that indicate an existing release, a past release, or a 

material threat of release of any hazardous substances or petroleum products into structures on the 

property or into the ground, groundwater, or surface water of the property. The term includes 

hazardous substances or petroleum products even under conditions in compliance with laws. The 

term is not intended to include de minimis conditions that generally do not present a material risk 

of harm to public health or the environment and that generally would not be the subject of an 

enforcement action if brought to the attention of appropriate governmental agencies. 

Additionally, the term historical REC refers to an environmental condition associated with the

1.0 Introduction 

 

Analytical Environmental Services 1-3 Lytton 4.11-Acres 

207513 Phase I Environmental Site Assessment

Subject Property, including a past release of any hazardous substance or petroleum product, 

which in the past would have been considered a REC, however such condition has since been 

remediated. Historical RECs will therefore be included in this Phase I ESA (ASTM, 2006). 

1.3 LIMITATIONS AND EXCEPTIONS 

No ESA can completely eliminate uncertainty regarding the potential for RECs in connection 

with a property. Conformance of this assessment with ASTM Standard Practice E 1527-05 will 

reduce, but not eliminate, uncertainty regarding the potential for RECs in connection with the 

Subject Property. While AES has made every effort to discover and interpret available historical 

and current information on the property within the time available, the possibility for undiscovered 

contamination to be present remains. AES’s report is a best-effort collection and interpretation of 

available information consistent with industry standards for the completion of Phase I ESAs. 

This ESA is based on a site reconnaissance of the Subject Property, searches of government 

hazardous materials databases, and interviews with individuals familiar with the historical uses of 

the Subject Property. Physical testing of soil or groundwater was not within the scope of this 

assessment. Asbestos containing building materials (ACM) and lead-based paint surveys were 

not included. Information was obtained for this ESA to comply with ASTM guidelines. 

1.4 METHODOLOGY 

A variety of data sources were consulted in completing this Phase I ESA. The following subsections describe the methods used and the data sources consulted to accomplish each task.

1.4.1 HISTORICAL REVIEW 

Previous land uses and history of the Subject Property were researched in an effort to identify 

RECs at or near the Subject Property. Historical aerial photographs (Appendix A) and

topographic maps (Appendix B) from different decades were examined for the presence of 

aboveground storage tanks, industrial buildings, gas station canopies and/or pump islands, as well 

as other indications of bulk hazardous material storage within the study area. Sanborn Fire 

Insurance Maps (Appendix C) document historical property use through abbreviations and map 

symbols that identify commercial, industrial, residential and other land uses. 

1.4.2 DATABASE SEARCHES 

Database searches were conducted for records of known storage tank sites and known sites of 

hazardous materials generation, storage, or release. Available information from federal, state, 

and local agency lists of: (a) known or potential hazardous waste sites and landfills; (b) sites 

currently under investigation for environmental violations; (c) sites which manufacture, generate, 
1.0 Introduction 

 

Analytical Environmental Services 1-4 Lytton 4.11-Acres 

207513 Phase I Environmental Site Assessment

use, store, and/or dispose of hazardous materials or hazardous wastes; (d) sites which have 

underground storage tanks (USTs); and (e) sites with recorded violations of regulations 

concerning USTs and hazardous materials/hazardous wastes. The database search is intended to 

identify facilities that may have the potential to impact surface and subsurface conditions on the 

Subject Property. A full listing of sites within the vicinity of the Subject Property is provided in 

Appendix D.

1.4.3 SITE RECONNIASSANCE 

Melissa Oberti from AES conducted a reconnaissance inspection of the Subject Property and 

adjacent properties on February 22, 2010. The purpose of the site reconnaissance is to examine 

the property for obvious physical indications of improper hazardous substance or petrochemical 

disposal such as stained soil or asphalt, stressed vegetation, sumps, partially buried drums, bulk 

underground fuel storage tanks, and other obvious signs of hazardous materials involvement. In 

addition, adjacent properties were visually inspected to the extent possible without trespassing on 

private property to determine if current land uses would affect the planned uses of Subject 

Property. 

1.5 DEVIATIONS AND DATA GAPS 

ASTM Standard 1527-05 requires any significant data gaps, deviations and deletions from the 

ASTM Standard to be identified and commented on in the Phase I. A significant data gap would 

be one that affected the ability to identify a REC on the Subject Property or adjacent properties. 

Due to the rural location of the Subject Property, Sanborn Fire Insurance maps were not available 

for the Subject Property. Because there is no historical data or physical indications that the 

property has ever been developed or occupied by a business that would have produced hazardous 

materials, the lack of Sanborn Fire Insurance maps is not considered a significant data gap for this 

Phase I ESA.

1.6 CREDENTIALS 

Melissa Oberti prepared this report under the professional supervision of David Zweig, P.E., who 

qualifies as an environmental professional (EP) as defined in the ASTM Standard 1527-05 [40 

CFR §312.10(b)]. The signatures of Melissa Oberti and David Zweig appear in Section 6.0 of 

this Phase I and their resumes are included as Appendix G.

Department of Planning and Zoning 

AES reviewed the Sonoma County Planning Department website (http://www.sonomacounty.org/prmd/docs/zoning/index.htm) for the zoning of the Subject Property. The Subject 

Property is zoned AR (Agriculture and Residential District), which is consistent with the current 

location and land use. 

Electrical Utility Company 

AES spoke with a representative of the owners on February 22, 2010 who confirmed that PG&E 

provides electrical and gas utilities to the Subject Property. 

Other Local Environmental Records Sources 

AES reviewed the California Regional Water Quality Control Board’s (CRWQCB) Geotracker 

website for listings of underground storage tanks (USTs), leaking underground storage tanks 

(LUSTs), or spill cases in association with petroleum chemicals at the Subject Property (SWRCB, 

2008). The Geotracker website had no listing of USTs, LUSTs, and spill cases at the Subject 

Property. The nearest listing is approximately 0.94 miles southwest of the Subject Property in 

response to an UST that was removed in 1991 showing signs of leakage. 

2.4 HYDROLOGY

One domestic well is located on the Subject Property. Based on the Department of Water 

Resources groundwater data (reference well located 0.3 miles northwest from the Subject 

Property), the depth to groundwater ranges from approximately 113 to 127 feet below ground 

surface (bgs) with a groundwater gradient generally towards the east (DWR, 2010). Estimated 

groundwater levels and/or flow direction(s) may vary due to seasonal fluctuations in 

precipitation, local usage demands, geology, underground structures, or dewatering operations. 

From the northern portion of the Subject Property, surface water drains primarily toward the 

northeast. From remaining portions of the Subject Property, surface water drains primarily to a 

topographic low spot, which is roughly in the middle of the Subject Property. 

2.5 GEOLOGY AND SOIL

AES reviewed The EDR-Radius Map with Geocheck regulatory database report (EDR database 

report). According to information provided in the EDR database report, the rock stratigraphic 

unit at the Subject Property is Cenozoic, which is in the Quaternary system and series. Soils in 

the vicinity of the Subject Property include loam at depths ranging between zero and 14 inches 

below ground surface (bgs). Soils at depths ranging between 14 and 22 inches bgs are classified 

as sandy clay loam. Soils at depths ranging between 22 and 29 inches bgs are classified as clay. 

Soils at depths ranging between 29 and 57 inches bgs are classified as cemented. The hydrologic 

group rating for soils in this area is generally Class C, which indicates soils that exhibit slow 

water infiltration rates with soil layers impeding the downward movement of water.

2.6 CURRENT USES OF THE SUBJECT PROPERTY

Melissa Oberti from AES performed a site reconnaissance survey of the Subject Property on 

February 22, 2010. The Subject Property is developed with a two-story single family home, 

associated residential landscape, a barn, and storage structure. The southern portion of the 

Subject Property consists of pasture. Site photos showing conditions of the Subject Property 

during the site visit are shown in Figure 4 in Section 3.0. 

2.7 HISTORIC USES OF THE SUBJECT PROPERTY

2.7.1 AERIAL PHOTOGRAPHS

AES reviewed available historic aerial photographs (Appendix A) for information regarding past 

uses of the Subject Property and surrounding areas. The following aerial photographs were 

available for review: 1952 (1”=555’), 1965 (1”=333’), 1974 (1’=541’), 1982 (1”= 690’), 1993 

(1”= 666’), 1998 (1”= 666’), and 2005 (1”= 604’). Aerial photographs were of varying scale and 

clarity. Historical aerial images offer detailed review of previous land uses on the Subject 

Property and adjacent properties. 

1952 and 1965 

The Subject Property is developed with several structures and the remaining southern portion 

appears to be pasture. It appears that two structures are visible directly to the east. Windsor 

River Road is visible to the north. The adjacent properties to the northwest appear to be used for 

agriculture, with a former prisoner of war camp (Appendix D) clearly visible to the northwest of 

the Subject Property. Further details on this camp are provided in Section 4.2.2. The adjacent 

properties to the south and west appear to be undeveloped with oak woodland. 

1974 and 1982 

The Subject Property appears to be developed with several structures and the remaining southern 

portion appears to be pasture. The 1974 aerial photograph does not clearly depict the Subject 

Property due to poor resolution in the photograph; however conditions appear to be consistent 

with the 1982 aerial photograph. It appears that several structures are visible directly to the east. 

Windsor River Road is visible to the north beyond which appears to be pasture with a few 

structures. The adjacent properties to the south and west appear to be undeveloped with oak 

woodland. 

1993 and 1998 

The 1993 and 1998 aerial photos indicate several structures located on the Subject Property and 

the remaining southern portion appears to be pasture. Several structures are visible directly to the 

east. Windsor River Road is visible to the north beyond which are several structures. The 
2.0 Site Description

adjacent properties to the west appear to be undeveloped with oak woodland. The adjacent 

properties to the south appear to be pasture and vineyards. 

2005

The 2005 aerial photograph shows the Subject Property developed in its current configuration. 

The residential portion of property appears consistent with existing conditions and the existing 

barn and storage structure are visible on the property. Two structures are visible directly to the 

east. Windsor River Road is visible to the north beyond which are several structures. The 

adjacent property to the west appears to be undeveloped with oak woodland. The adjacent 

properties to the south appear to be pasture and vineyards. 

2.7.2 HISTORIC TOPOGRAPHIC MAPS 

AES reviewed available historic USGS Topographic Quadrangles (Appendix B) for information 

regarding past uses of the Subject Property. The Healdsburg, California Topographic 

Quadrangle maps dated 1940, 1955, and 1993 were available for review. The 1940 topographic 

map depicts the Subject Property as being developed with one structure. The 1955 and 1993 

topographic maps depict the Subject Property as being developed with three structures. No other 

features are presented on the Subject Property. The 1993 topographic map indicates several 

structures to the north and east on adjacent properties. 

2.8 SANBORN FIRE INSURANCE MAPS 

Sanborn Fire Insurance Maps do not provide coverage of the Subject Property. Documentation of 

the lack of coverage is included in Appendix C.

2.9 OTHER PHYSICAL SETTING SOURCES 

Wetlands Map 

According to the Overview Map located with the regulatory database report, which references 

information provided by the National Wetlands Inventory (NWI) Map for the Healdsburg NWI 

Quad, no wetlands are located on the property. A copy of the Overview Map is included in the 

regulatory database report in Appendix D. 

Floodplain Map 

According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map 

(FIRM) number 06097C0562E (effective December 2, 2008), the Subject Property is located in

SECTION 3.0 

SITE RECONNAISSANCE AND INTERVIEWS 

3.1 OBJECTIVE 

The objective of the site reconnaissance is to identify current or historic hazardous materials 

involvement on the Subject Property or in the vicinity of the Subject Property. Hazardous 

materials involvement or signature environmental conditions include the presence or likely 

presence of any hazardous materials or petroleum products that indicate an existing release, past 

release, or a threat of release into any structure on the property, soil, or groundwater. Signs of 

possible hazardous materials involvement would include any indications of underground storage 

tanks existing on the Subject Property, stained soils and/or unusual odors originating from the 

Subject Property, indications of an excavation or removal of soils, including patched asphalt and 

large debris piles, and other obvious signs of hazardous materials involvement. 

Interviews included contacting individuals familiar with the Subject Property and adjacent 

properties that are knowledgeable of historic and existing conditions relative to hazardous 

materials. 

3.2 SITE RECONNAISSANCE FINDINGS 

Melissa Oberti from AES conducted a site reconnaissance of the Subject Property on February 

22, 2010. Adjacent properties were observed to the extent possible without trespassing. Figure 4 

provides photographs that show the site conditions at the time of the site visit. Notable features 

and environmental conditions are summarized below:

RECORDS REVIEW 

4.1 DATABASE SEARCH

Database searches were conducted for records of known storage tank sites and known sites of 

hazardous materials generation, storage, and/or contamination. Databases were searched for sites 

and listings up to one mile from the Subject Property. The environmental database review was 

accomplished by using the services of a computerized search firm Environmental Data 

Resources, Inc. (EDR). EDR uses a geographical information system to plot locations of past or 

previous hazardous materials involvement. AES reviewed the EDR report to determine if the 

Subject Property and adjacent sites are listed on regulatory agency databases. The purpose is to 

determine if adjacent sites will impact surface and/or subsurface conditions on the Subject 

Property. Included in the EDR database report was a list of “unmapped sites”. AES reviewed the 

list of unmapped sites for the properties that may be located within the search radius specified for 

each governmental database. These sites do not appear to be located within the applicable search 

radius of the Subject Property. The complete list of reviewed databases is provided in the EDR 

report, included in Appendix D and is summarized in Table 4-1. Information on past and/or 

current hazardous materials involvement involving adjacent properties is summarized in Section 

4.2.2. 

4.2 HAZARDOUS MATERIALS INVOLVEMENT 

A regulatory agency database report was performed to identify locations of past and/or current 

hazardous materials involvement. Regulatory agency databases were searched for records of 

known storage tank sites and known sites of hazardous materials generation, storage, or 

contamination, or where violations pertaining to storage and/or use of hazardous materials have 

occurred. Databases were searched for sites and listings up to one mile from a point roughly 

equivalent to the center of Subject Property. Although a site may be listed within the database 

report, this does not mean the site is currently contaminated or will impact the environmental 

quality of the Subject Property. It should be noted that the database search is only as accurate as 

the data entered into the government agency maintained databases and the date on which those 

databases were last updated. Installation of underground storage tanks or hazardous material 

releases, if not reported to the appropriate agency, would not be listed on any of the databases 

searched.

207513 Phase I Environmental Site Assessment

4.2.2 ADJACENT PROPERTIES

One site was identified within one mile of the Subject Property: 

The Windsor Prisoner of War Labor Camp (Labor Camp) (Appendix D) is located approximately 

0.34 miles northwest of the Subject Property and is listed on the FUDS database. The Labor 

Camp once comprised 66.74 acres approximately 1 mile west of the Town of Windsor, 6 miles 

south of Healdsburg. The site was relinquished to an unknown party in 1946 and then 

retransferred to the United States Department of Agriculture. Currently, three of the former 

bunkhouses are used as residences and open space is used for pastures. According to the 

database, no potential hazards related to Department of Defense activity have been located on the 

66.74 acre site. Based on the current regulatory status and lack of violations reported, this site is 

not likely to pose a risk to the environmental quality of the Subject Property.

207513 Phase I Environmental Site Assessment

SECTION 5.0 

FINDINGS AND CONCLUSIONS 

This Phase I ESA was performed in conformance with the scope and limitations of ASTM 

Standard Practice E1527-05 and BIA guidelines (602 DM Chapter 2). Based on information 

gathered while conducting this Phase I ESA, AES observed the following environmental 

conditions:

x The 4.11-acre Subject Property is comprised of pasture, an occupied private residence, a 

single-story barn, one single-story storage structure, and a three-car carport. The earliest 

available historic aerial photographs from EDR show that the Subject Property was 

developed with several structures in 1952. 

x Several electric transformers attached to power poles are located adjacent to the Subject 

Property. No leaks were observed. 

x Individual containers of various pesticides and plant nutrients were stored in the service 

area behind the southern portion of the two-story residence. The chemicals were stored 

within approved commercial containers and no surface staining or odor was observed. 

x Approximately 15 paint cans were stored in the storage shed. The paints were stored 

within approved commercial containers and no surface staining or odor was observed 

inside or outside the shed. 

AES has performed this Phase I ESA in conformance with the scope and limitations of ASTM 

Practice E 1527. Any exceptions to, or deletions from, this practice are described in Section 1.0

of this report. This assessment has revealed no evidence of RECs in connection with the Subject 

Property. Based on the findings and conclusions of this Phase I ESA, the listed environmental 

conditions above do not warrant any further study.

SURROUNDING SITES: SEARCH RESULTS

Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on

a relative (not an absolute) basis. Relative elevation information between sites of close proximity

should be field verified. Sites with an elevation equal to or higher than the target property have been

differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed

data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

Reuse Program’s (SMBRP’s) EnviroStor database identifes sites that have known contamination or sites for which

there may be reasons to investigate further. The database includes the following site types: Federal

Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State

Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information

that was available in CalSites, and provides additional site information, including, but not limited to,

identification of formerly-contaminated properties that have been released for reuse, properties where

environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk

characterization information that is used to assess potential impacts to public health and the environment at

contaminated sites.

 A review of the ENVIROSTOR list, as provided by EDR, and dated 02/08/2010 has revealed that there is

 1 ENVIROSTOR site within approximately 1 mile of the target property.

CERCLIS-NFRAP: CERCLIS No Further Remedial Action Planned

Archived sites are sites that have been removed and archived from the inventory of CERCLIS sites. Archived status

indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined

no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates

this decision was not appropriate or other considerations require a recommendation for listing at a later time.

This decision does not necessarily mean that there is no hazard associated with a given site; it only means that,

based upon available information, the location is not judged to be a potential NPL site.

Local Brownfield lists

US BROWNFIELDS: A Listing of Brownfields Sites

Included in the listing are brownfields properties addresses by Cooperative Agreement Recipients and brownfields

properties addressed by Targeted Brownfields Assessments. Targeted Brownfields Assessments-EPA’s Targeted Brownfields

Assessments (TBA) program is designed to help states, tribes, and municipalities--especially those without EPA

Brownfields Assessment Demonstration Pilots--minimize the uncertainties of contamination often associated with

brownfields. Under the TBA program, EPA provides funding and/or technical assistance for environmental assessments

at brownfields sites throughout the country. Targeted Brownfields Assessments supplement and work with other efforts

under EPA’s Brownfields Initiative to promote cleanup and redevelopment of brownfields. Cooperative Agreement

Recipients-States, political subdivisions, territories, and Indian tribes become Brownfields Cleanup Revolving

Loan Fund (BCRLF) cooperative agreement recipients when they enter into BCRLF cooperative agreements with the

U.S. EPA. EPA selects BCRLF cooperative agreement recipients based on a proposal and application process. BCRLF

cooperative agreement recipients must use EPA funds provided through BCRLF cooperative agreement for specified

brownfields-related cleanup activities.

UMTRA: Uranium Mill Tailings Sites

Uranium ore was mined by private companies for federal government use in national defense programs. When the mills

shut down, large piles of the sand-like material (mill tailings) remain after uranium has been extracted from

the ore. Levels of human exposure to radioactive materials from the piles are low; however, in some cases tailings

were used as construction materials before the potential health hazards of the tailings were recognized.

EDR PROPRIETARY RECORDS

EDR Proprietary Records

Manufactured Gas Plants: EDR Proprietary Manufactured Gas Plants

The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)

compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s

to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture

of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,

such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds

are potentially hazardous to human health and the environment. The byproduct from this process was frequently

disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil

and groundwater contamination.

USGS 7.5’ Digital Elevation Model (DEM)

Source: United States Geologic Survey

EDR acquired the USGS 7.5’ Digital Elevation Model in 2002 and updated it in 2006. The 7.5 minute DEM corresponds

to the USGS 1:24,000- and 1:25,000-scale topographic quadrangle maps. The DEM provides elevation data

with consistent elevation units and projection.

Scanned Digital USGS 7.5’ Topographic Map (DRG)

Source: United States Geologic Survey

A digital raster graphic (DRG) is a scanned image of a U.S. Geological Survey topographic map. The map images

are made by scanning published paper maps on high-resolution scanners. The raster image

is georeferenced and fit to the Universal Transverse Mercator (UTM) projection.

HYDROLOGIC INFORMATION

Flood Zone Data: This data, available in select counties across the country, was obtained by EDR in 2003 & 2009 from the Federal

Emergency Management Agency (FEMA). Data depicts 100-year and 500-year flood zones as defined by FEMA.

NWI: National Wetlands Inventory. This data, available in select counties across the country, was obtained by EDR

in 2002 and 2005 from the U.S. Fish and Wildlife Service.

HYDROGEOLOGIC INFORMATION

AQUIFLOW Information System R

Source: EDR proprietary database of groundwater flow information

EDR has developed the AQUIFLOW Information System (AIS) to provide data on the general direction of groundwater

flow at specific points. EDR has reviewed reports submitted to regulatory authorities at select sites and has

extracted the date of the report, hydrogeologically determined groundwater flow direction and depth to water table

information.

The U.S. Department of Agriculture’s (USDA) Natural Resources Conservation Service (NRCS) leads the national

Conservation Soil Survey (NCSS) and is responsible for collecting, storing, maintaining and distributing soil

survey information for privately owned lands in the United States. A soil map in a soil survey is a representation

of soil patterns in a landscape. Soil maps for STATSGO are compiled by generalizing more detailed (SSURGO)

soil survey maps.

Telephone: 800-672-5559

SSURGO is the most detailed level of mapping done by the Natural Resources Conservation Services, mapping

scales generally range from 1:12,000 to 1:63,360. Field mapping methods using national standards are used to

construct the soil maps in the Soil Survey Geographic (SSURGO) database. SSURGO digitizing duplicates the

original soil survey maps. This level of mapping is designed for use by landowners, townships and county

natural resource planning and management.

Countermeasure Plan. In cooperation with Sage Environmental, prepared a 

SPCCP for a cogeneration facility in King City. The American I facility uses a 

gas turbine cogeneration unit to generate electricity and provide steam and hot 

water to a neighboring food processing plant. Because of the large quantities of 

fuels and other chemicals stored at the facility, a SPCCP was required by the 

Regional Water Quality Control Board (RWQCB). In requiring the SPCCP, the 

RWQCB was implementing the regulations contained in Title 40 of the Code of 

Federal Regulations, Part 112. The SPCCP consists of an inventory of storage 

tanks and containment systems at the facility and recommendations to prevent 

hazardous materials from being released into nearby surface waters. 

 Defense Distribution Region West Sharpe Depot Storm Water Pollution 

Prevention Plan, Lathrop, California. Under contract to the US Army Corps of

SECTION 1.0 

INTRODUCTION 

1.1 PURPOSE 

Analytical Environmental Services (AES) has prepared this Environmental Site Assessment 

(ESA) in conformance with the Bureau of Indian Affairs (BIA) guidelines (602 DM Chapter 2) 

and the American Society for Testing and Materials (ASTM) Standard Practice E 1527-05, which 

specifies the appropriate inquiry requirement for the innocent landowner defense under the 

Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). This 

ESA encompasses two legal parcels (APN 066-050-040 and 066-050-047) totaling approximately 

20 acres, located in the County of Sonoma, California (Figure 1). As such, the use of the term 

“Subject Property” refers to the entire 20-acre property unless otherwise stated. The purpose of 

this assessment is to identify Recognized Environmental Conditions (RECs) that may affect 

future uses of the Subject Property. 

This ESA covers the Subject Property, adjacent areas, and surrounding known sources of 

contamination, up to 1.0 mile from the Subject Property. A site reconnaissance inspection of the 

Subject Property and adjacent properties was performed and relevant database listings of 

hazardous materials sites, waste generators, and underground storage tanks were reviewed (EDR, 

2010). AES also reviewed historical aerial photographs for the Subject Property. 

1.2 RECOGNIZED ENVIRONMENTAL CONDITIONS 

The term REC refers to the presence or likely presence of any hazardous substances or petroleum 

products on a property under conditions that indicate an existing release, a past release, or a 

material threat of release of any hazardous substances or petroleum products into structures on the 

property or into the ground, groundwater, or surface water of the property. The term includes 

hazardous substances or petroleum products even under conditions in compliance with laws. The 

term is not intended to include de minimis conditions that generally do not present a material risk 

of harm to public health or the environment and that generally would not be the subject of an 

enforcement action if brought to the attention of appropriate governmental agencies. 

Additionally, the term historical REC refers to an environmental condition associated with the 
Lytton 20.0-Acre Phase I ESA / 207513

1.0 Introduction 

 

Analytical Environmental Services 1-3 Lytton 20-Acres 

207513 Phase I Environmental Site Assessment

Subject Property, including a past release of any hazardous substance or petroleum product, 

which in the past would have been considered a REC, however such condition has since been 

remediated. Historical RECs will therefore be included in this Phase I ESA (ASTM, 2006). 

1.3 LIMITATIONS AND EXCEPTIONS 

No ESA can completely eliminate uncertainty regarding the potential for RECs in connection 

with a property. Conformance of this assessment with ASTM Standard Practice E 1527-05 will 

reduce, but not eliminate, uncertainty regarding the potential for RECs in connection with the 

Subject Property. While AES has made every effort to discover and interpret available historical 

and current information on the property within the time available, the possibility for undiscovered 

contamination to be present remains. AES’s report is a best-effort collection and interpretation of 

available information consistent with industry standards for the completion of Phase I ESAs. 

This ESA is based on a site reconnaissance of the Subject Property, searches of government 

hazardous materials databases, and interviews with individuals familiar with the historical uses of 

the Subject Property. Physical testing of soil or groundwater was not within the scope of this 

assessment. Asbestos containing building materials (ACM) and lead-based paint surveys were 

not included. Information was obtained for this ESA to comply with ASTM guidelines. 

1.4 METHODOLOGY 

A variety of data sources were consulted in completing this Phase I ESA. The following subsections describe the methods used and the data sources consulted to accomplish each task.

1.4.1 HISTORICAL REVIEW 

Previous land uses and history of the Subject Property were researched in an effort to identify 

RECs at or near the Subject Property. Historical aerial photographs (Appendix A) and 

topographic maps (Appendix B) from different decades were examined for the presence of 

aboveground storage tanks, industrial buildings, gas station canopies and/or pump islands, as well 

as other indications of bulk hazardous material storage within the study area. Sanborn Fire 

Insurance Maps (Appendix C) document historical property use through abbreviations and map 

symbols that identify commercial, industrial, residential and other land uses. 

1.4.2 DATABASE SEARCHES 

Database searches were conducted for records of known storage tank sites and known sites of 

hazardous materials generation, storage, or release. Available information from federal, state, 

and local agency lists of: (a) known or potential hazardous waste sites and landfills; (b) sites 

currently under investigation for environmental violations; (c) sites which manufacture, generate, 
1.0 Introduction 

 

Analytical Environmental Services 1-4 Lytton 20-Acres 

207513 Phase I Environmental Site Assessment

use, store, and/or dispose of hazardous materials or hazardous wastes; (d) sites which have 

underground storage tanks (USTs); and (e) sites with recorded violations of regulations 

concerning USTs and hazardous materials/hazardous wastes. The database search is intended to 

identify facilities that may have the potential to impact surface and subsurface conditions on the 

Subject Property. A full listing of sites within the vicinity of the Subject Property is provided in 

Appendix D. 

1.4.3 SITE RECONNIASSANCE 

David Sawyer from AES conducted a reconnaissance inspection of the Subject Property and 

adjacent properties on May 21, 2010. The purpose of the site reconnaissance is to examine the 

property for obvious physical indications of improper hazardous substance or petrochemical 

disposal such as stained soil or asphalt, stressed vegetation, sumps, partially buried drums, bulk 

underground fuel storage tanks, and other obvious signs of hazardous materials involvement. In 

addition, adjacent properties were visually inspected to the extent possible without trespassing on 

private property to determine if current land uses would affect the planned uses of Subject 

Property. 

1.5 DEVIATIONS AND DATA GAPS 

ASTM Standard 1527-05 requires any significant data gaps, deviations and deletions from the 

ASTM Standard to be identified and commented on in the Phase I. A significant data gap would 

be one that affected the ability to identify a REC on the Subject Property or adjacent properties. 

Due to the rural location of the Subject Property, Sanborn Fire Insurance maps were not available 

for the Subject Property. Because there is no historical data or physical indications that the 

property has ever been developed or occupied by a business that would have produced hazardous 

materials, the lack of Sanborn Fire Insurance maps is not considered a significant data gap for this 

Phase I ESA. 

1.6 CREDENTIALS 

David Sawyer prepared this report under the professional supervision of David Zweig, P.E., who 

qualifies as an environmental professional (EP) as defined in the ASTM Standard 1527-05 [40 

CFR §312.10(b)]. The signatures of David Sawyer and David Zweig appear in Section 6.0 of 

this Phase I and their resumes are included as Appendix G.

SITE DESCRIPTION 

2.1 LOCATION AND LEGAL DESCRIPTION 

The Subject Property is located near the intersection of Windsor River Road and Old Camp Lane, 

in unincorporated Sonoma County just west of the Town of Windsor, California (Figures 2 and

3). The Sonoma County assessors’ parcel number (APN) for the Subject Property is 066-050-040 

and 066-050-047 (totaling approximately 20-acres). 

2.2 SITE AND VICINITY CHARACTERISTICS 

The Subject Property is comprised of a total of 20 acres, which is developed with two single 

residence houses, a storage structure, and a dilapidated barn structure. Approximately threefourths of the Subject Property (southern portion) consists of pasture. The topography of the 

Subject Property ranges in elevation from approximately 115 feet to 155 feet above mean sea 

level (amsl). Two single-story single-family homes, a three-car carport, a barn, and a storage 

structure are located within the Subject Property’s boundaries. The residential and irrigation 

water demands on the property are met by an on-site well with one on-site septic system 

providing wastewater treatment and disposal for both homes. 

Regional access is provided by US Highway 101 (US 101), which runs in a general south-north 

direction and is located 1.3 miles east of the Subject Property. Local access to the Subject 

Property from US 101 is provided by Windsor River Road, which is a two-lane County road that 

traverses east for two miles from the Old Redwood Highway near US 101 to Eastside Road to the 

west of the Subject Property. The right-of-way for Windsor River Road adjoins the southern 

boundary of the parcel. Direct access to the Subject Property is located approximately 440 feet 

east of the Windsor River Road / Old Camp Road intersection (Figure 3). 

2.3 LOCAL ENVIRONMENTAL RECORDS SOURCES

Department of Planning and Zoning 

Zoning designations on the Subject Property were reviewed on the Sonoma County Planning 

Department website (http://www.sonoma-county.org/prmd/docs/zoning/index.htm). The Subject 

Property is zoned AR (Agriculture and Residential District), which is consistent with the current 

location and land use. The eastern 10.0-acre parcel (APN: 066-050-047), located within the City 

of Windsor, is designated as low density residential. The western parcel (APN: 066-050-040) is 

located within the City of Windsor Sphere of Influence area and is designated as an agricultural 

buffer zone with low density residential. 

Electrical Utility Company 

The property owner confirmed during the site visit, on May 21, 2010, that PG&E provides 

electrical and gas utilities to the Subject Property. 

Other Local Environmental Records Sources 

The California Regional Water Quality Control Board’s (CRWQCB) Geotracker website was 

reviewed for listings of underground storage tanks (USTs), leaking underground storage tanks 

(LUSTs), or spill cases in association with petroleum chemicals at the Subject Property (SWRCB, 

2008). The Geotracker website had no listing of USTs, LUSTs, and spill cases at the Subject 

Property. The nearest listing is approximately 0.95 miles west of the Subject Property in 

response to an LUST that was removed in 1987 showing signs of leakage. 

2.4 HYDROLOGY

One domestic well is located on the Subject Property. Based on the Department of Water 

Resources groundwater data (reference well located 0.3 miles west from the Subject Property), 

the depth to groundwater ranges from approximately 113 to 127 feet below ground surface (bgs) 

with a groundwater gradient generally towards the east (DWR, 2010). Estimated groundwater 

levels and/or flow direction(s) may vary due to seasonal fluctuations in precipitation, local usage 

demands, geology, underground structures, or dewatering operations. From the northern portion 

of the Subject Property, surface water drains primarily toward the southeast through on-site 

drainages. From remaining portions of the Subject Property, surface water drains primarily to a 

topographic low spot, which is roughly in the middle of the Subject Property. 

2.5 GEOLOGY AND SOIL 

According to information provided in the The EDR-Radius Map with Geocheck regulatory 

database report (EDR database report), the rock stratigraphic unit at the Subject Property is 

Cenozoic, which is in the Quaternary system and series. Soils in the vicinity of the Subject 

Property include loam at depths ranging between zero and 14 inches below ground surface (bgs). 

Soils at depths ranging between 14 and 22 inches bgs are classified as sandy clay loam. Soils at 

depths ranging between 22 and 29 inches bgs are classified as clay. Soils at depths ranging 
2.0 Site Description 

Analytical Environmental Services 2-5 Lytton 20-Acres 

207513 Phase I Environmental Site Assessment

between 29 and 57 inches bgs are classified as cemented. The hydrologic group rating for soils in 

this area is generally Class C, which indicates soils that exhibit slow water infiltration rates with 

soil layers impeding the downward movement of water. 

2.6 CURRENT USES OF THE SUBJECT PROPERTY 

A site reconnaissance survey of the Subject Property on May 21, 2010 was performed by David 

Sawyer. The southwestern corner of the Subject Property is developed with two single-story 

single family homes, a storage structure, and dilapidated barn structure. The remainder of the 

Subject Property consists of pasture. Site photos showing conditions of the Subject Property 

during the site visit are shown in Figure 4 in Section 3.0. 

2.7 HISTORIC USES OF THE SUBJECT PROPERTY 

2.7.1 AERIAL PHOTOGRAPHS 

Available historic aerial photographs (Appendix A) were reviewed for information regarding 

past uses of the Subject Property and surrounding areas. The following aerial photographs were 

available for review: 1953 (1”=555’), 1965 (1”=333’), 1974 (1’=541’), 1982 (1”= 690’), 1993 

(1”= 666’), 1998 (1”= 666’), and 2005 (1”= 604’). Aerial photographs were of varying scale and 

clarity. Historical aerial images offer detailed review of previous land uses on the Subject 

Property and adjacent properties. 

1953 and 1965 

The Subject Property is undeveloped. Windsor River Road is visible to the immediate south of 

the Subject Property. The adjacent properties to the west are a former prisoner of war camp 

(Appendix D) clearly visible to the immediate west of the Subject Property. Further details on 

this camp are provided in Section 4.2.2. The adjacent properties to the east appear to be 

undeveloped with agricultural use. 

1974 and 1982 

The Subject Property appears to be developed with several structures and the remaining eastern 

portion appears to be pasture. It appears that the majority of the structures associated with the 

prisoner of war camp have been removed. The adjacent properties to the north and east appear to 

be undeveloped pastureland. 

1993 and 1998 

The 1993 and 1998 aerial photos indicate the continued existence of the structures on the Subject 

Property. The remaining eastern portion appears to be pasture, as well as pasture to the north and 

northeast. The adjacent properties to the east appear to be have been developed as a subdivision.

The residential portion of property appears consistent with existing conditions and the existing 

barn and storage structure are visible on the property. River Road is visible to the south beyond 

which are several structures. The adjacent property to the west appears to be developed with 

rural residential, while the east contains a subdivision. The adjacent properties to the north 

appear to be pasture. 

2.7.2 HISTORIC TOPOGRAPHIC MAPS 

Available historic USGS Topographic Quadrangles (Appendix B) were reviewed for information 

regarding past uses of the Subject Property. The Healdsburg, California Topographic 

Quadrangle maps dated 1940, 1955, and 1993 were available for review. The 1940 and 1955 

topographic maps depicts the Subject Property as being undeveloped. The 1993 topographic 

maps depict the Subject Property as being developed with two structures. No other features are 

presented on the Subject Property. The 1993 topographic map indicates several structures to the 

south and west on adjacent properties.

SECTION 3.0 

SITE RECONNAISSANCE AND INTERVIEWS 

3.1 OBJECTIVE 

The objective of the site reconnaissance is to identify current or historic hazardous materials 

involvement on the Subject Property or in the vicinity of the Subject Property. Hazardous 

materials involvement or signature environmental conditions include the presence or likely 

presence of any hazardous materials or petroleum products that indicate an existing release, past 

release, or a threat of release into any structure on the property, soil, or groundwater. Signs of 

possible hazardous materials involvement would include any indications of underground storage 

tanks existing on the Subject Property, stained soils and/or unusual odors originating from the 

Subject Property, indications of an excavation or removal of soils, including patched asphalt and 

large debris piles, and other obvious signs of hazardous materials involvement. 

Interviews included contacting individuals familiar with the Subject Property and adjacent 

properties that are knowledgeable of historic and existing conditions relative to hazardous 

materials. 

3.2 SITE RECONNAISSANCE FINDINGS 

A site reconnaissance of the Subject Property on May 21, 2010 was performed by David Sawyer 

of AES. Adjacent properties were observed to the extent possible without trespassing. Figure 4 

and Figure 5 provide photographs that show the site conditions at the time of the site visit. 

Notable features and environmental conditions are summarized below: 

• The Subject Property comprises approximately 20 acres of partially developed land. The 

southwestern portion of the Subject Property consists of two single-story residences, a 

three-car carport, barn, and associated storage structure (Photo 1). The remainder of the 

Subject Property consists of pasture (Photo 2). 

• A water well is located between the residence and Windsor River Road (Photo 3). 

• Both of the residences are connected to a septic tank and leachfield system, located to the 

north of the two structures (Photo 4).

• Individual containers of chemical were stored in the carport and storage structure (Photo 

5). The chemicals were stored within approved commercial containers and no surface 

staining or odor was observed inside or outside the shed. 

• Approximately 15 five-gallon and 10-gallon paint cans were stored in the shed (Photo 6) 

and garage (Photo 7). The paint containers were stored in various conditions, however a 

majority appeared to be stored within approved commercial containers. No surface 

staining was observed inside the storage structure. 

• Oil and grease stains were found in the carport and in the garage (Photo 8).

• Fuel storage tanks were located in the storage structure (Photo 9). 

• Multiple empty 55 gallons barrels were located around the Subject Property. No surface 

staining was observed in the vicinity of these barrels (Photo 10). 

• No hazardous materials or indications of hazardous materials releases were observed 

within the structures or surrounding Subject Property. 

• An electric service line extends from a transformer located within the right of way along 

Windsor River Road. The Subject Property connects to this service line through a power 

pole, located between the residences and Windsor River Road (Photo 11). Two 

additional transformers are located adjacent to the Subject Property, along the western 

boundary (Photo 12). 

3.3 ADJACENT PROPERTIES 

A survey of adjacent properties was performed to the extent possible without trespassing during 

the May 21, 2010 site visit. The purpose was to identify adjacent businesses and determine if 

current land uses would affect the planned use of the Subject Property. Adjacent land uses are 

described below. 

• North: Undeveloped oak woodland, pasture and rural residences. 

• South: Windsor River Road is located to the immediate south. Several power lines with 

pole mounted transformers were observed along the Windsor River Roadway right-ofway north of the property boundary. No leaks associated with the transformers were 

observed. Beyond Windsor River Road are several rural residences and oak woodland. 

• West: Rural residential units within oak woodland.

RECORDS REVIEW 

4.1 DATABASE SEARCH

Database searches were conducted for records of known storage tank sites and known sites of 

hazardous materials generation, storage, and/or contamination. Databases were searched for sites 

and listings up to one mile from the Subject Property. The environmental database review was 

accomplished by using the services of a computerized search firm Environmental Data 

Resources, Inc. (EDR). EDR uses a geographical information system to plot locations of past or 

previous hazardous materials involvement. AES reviewed the EDR report to determine if the 

Subject Property and adjacent sites are listed on regulatory agency databases. The purpose is to 

determine if adjacent sites will impact surface and/or subsurface conditions on the Subject 

Property. Included in the EDR database report was a list of “unmapped sites”. The list of 

unmapped sites for the properties that may be located within the search radius specified for each 

governmental database were reviewed. These sites do not appear to be located within the 

applicable search radius of the Subject Property were reviewed. The complete list of reviewed 

databases is provided in the EDR report, included in Appendix D and is summarized in Table 4-

1. Information on past and/or current hazardous materials involvement involving adjacent 

properties is summarized in Section 4.2.2. 

4.2 HAZARDOUS MATERIALS INVOLVEMENT 

A regulatory agency database report was performed to identify locations of past and/or current 

hazardous materials involvement. Regulatory agency databases were searched for records of 

known storage tank sites and known sites of hazardous materials generation, storage, or 

contamination, or where violations pertaining to storage and/or use of hazardous materials have 

occurred. Databases were searched for sites and listings up to one mile from a point roughly 

equivalent to the center of Subject Property. Although a site may be listed within the database 

report, this does not mean the site is currently contaminated or will impact the environmental 

quality of the Subject Property. It should be noted that the database search is only as accurate as 

the data entered into the government agency maintained databases and the date on which those 

databases were last updated. Installation of underground storage tanks or hazardous material 

releases, if not reported to the appropriate agency, would not be listed on any of the databases 

searched.

4.2.2 ADJACENT PROPERTIES

One site was identified within one mile of the Subject Property: 

The Windsor Prisoner of War Labor Camp (Labor Camp) (Appendix D) is located approximately 

0.2 miles northwest of the Subject Property and is listed on the FUDS database. The Labor Camp 

once comprised 66.74 acres approximately 1 mile west of the Town of Windsor, 6 miles south of 

Healdsburg. The site was relinquished to an unknown party in 1946 and then retransferred to the 

United States Department of Agriculture. Currently, three of the former bunkhouses are used as 

residences and open space is used for pastures. According to the database, no potential hazards 

related to Department of Defense activity have been located on the 66.74 acre site. Based on the 

current regulatory status and lack of violations reported, this site is not likely to pose a risk to the 

environmental quality of the Subject Property.

207513 Phase I Environmental Site Assessment

SECTION 5.0 

FINDINGS AND CONCLUSIONS 

This Phase I ESA was performed in conformance with the scope and limitations of ASTM 

Standard Practice E1527-05 and BIA guidelines (602 DM Chapter 2). Based on information 

gathered while conducting this Phase I ESA, the following environmental conditions were 

observed: 

• The 20-acre Subject Property is comprised of pasture, two occupied private residences 

with an attached carport, a dilapidated barn, and a dilapidated storage structure. The 

earliest available historic aerial photographs from EDR show that the Subject Property 

was developed with several structures in 1974. 

• Several electric transformers attached to power poles are located adjacent to the Subject 

Property. No leaks were observed. 

• Approximately 12 empty 5-gallon fuel cans were located around the shed and barn area. 

No surface staining or odor was observed in the immediate vicinity of these barrels. 

• Numerous paint cans were stored in the garage, carport, and storage shed. The paints 

were stored in various containers. Some of these pain containers where showed improper 

storage and maintenance. Odor was evident inside the shed. 

This Phase I ESA was prepared in conformance with the scope and limitations of ASTM Practice 

E 1527. Any exceptions to, or deletions from, this practice are described in Section 1.0 of this 

report. This assessment has revealed no evidence of RECs in connection with the Subject 

Property. Based on the findings and conclusions of this Phase I ESA, the listed environmental 

conditions above do not warrant further study.

SURROUNDING SITES: SEARCH RESULTS

Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on

a relative (not an absolute) basis. Relative elevation information between sites of close proximity

should be field verified. Sites with an elevation equal to or higher than the target property have been

differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed

data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

ENVIROSTOR: The Department of Toxic Substances Control’s (DTSC’s) Site Mitigation and Brownfields

Reuse Program’s (SMBRP’s) EnviroStor database identifes sites that have known contamination or sites for which

there may be reasons to investigate further. The database includes the following site types: Federal

Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State

Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information

that was available in CalSites, and provides additional site information, including, but not limited to,

identification of formerly-contaminated properties that have been released for reuse, properties where

environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk

characterization information that is used to assess potential impacts to public health and the environment at

contaminated sites.

 A review of the ENVIROSTOR list, as provided by EDR, and dated 05/11/2010 has revealed that there is

 1 ENVIROSTOR site within approximately 1 mile of the target property.

Federal CERCLIS NFRAP site List

CERCLIS-NFRAP: CERCLIS No Further Remedial Action Planned

Archived sites are sites that have been removed and archived from the inventory of CERCLIS sites. Archived status

indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined

no further steps will be taken to list this site on the National Priorities List (NPL), unless information indicates

this decision was not appropriate or other considerations require a recommendation for listing at a later time.

This decision does not necessarily mean that there is no hazard associated with a given site; it only means that,

based upon available information, the location is not judged to be a potential NPL site.

US BROWNFIELDS: A Listing of Brownfields Sites

Included in the listing are brownfields properties addresses by Cooperative Agreement Recipients and brownfields

properties addressed by Targeted Brownfields Assessments. Targeted Brownfields Assessments-EPA’s Targeted Brownfields

Assessments (TBA) program is designed to help states, tribes, and municipalities--especially those without EPA

Brownfields Assessment Demonstration Pilots--minimize the uncertainties of contamination often associated with

brownfields. Under the TBA program, EPA provides funding and/or technical assistance for environmental assessments

at brownfields sites throughout the country. Targeted Brownfields Assessments supplement and work with other efforts

under EPA’s Brownfields Initiative to promote cleanup and redevelopment of brownfields. Cooperative Agreement

Recipients-States, political subdivisions, territories, and Indian tribes become Brownfields Cleanup Revolving

Loan Fund (BCRLF) cooperative agreement recipients when they enter into BCRLF cooperative agreements with the

U.S. EPA. EPA selects BCRLF cooperative agreement recipients based on a proposal and application process. BCRLF

cooperative agreement recipients must use EPA funds provided through BCRLF cooperative agreement for specified

brownfields-related cleanup activities.

Program Facility Sites with Deed / Land Use Restriction. The DTSC Site Mitigation and Brownfields Reuse Program

(SMBRP) list includes sites cleaned up under the program’s oversight and generally does not include current

or former hazardous waste facilities that required a hazardous waste facility permit. The list represents deed

restrictions that are active. Some sites have multiple deed restrictions. The DTSC Hazardous Waste Management

Program (HWMP) has developed a list of current or former hazardous waste facilities that have a recorded land

use restriction at the local county recorder’s office. The land use restrictions on this list were required by

the DTSC HWMP as a result of the presence of hazardous substances that remain on site after the facility (or

part of the facility) has been closed or cleaned up. The types of land use restriction include deed notice, deed

restriction, or a land use restriction that binds current and future owners.

EDR PROPRIETARY RECORDS

EDR Proprietary Records

Manufactured Gas Plants: EDR Proprietary Manufactured Gas Plants

The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)

compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’s

to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture

of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,

such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds

are potentially hazardous to human health and the environment. The byproduct from this process was frequently

disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil

and groundwater contamination.

PROJECTS  Defense Distribution Region West Sharpe Depot Effluent and Receiving 

Water Quality Assessment, Lathrop, California. Under contract to the US 

Army Corps of Engineers, prepared an ERWQA for the depot's wastewater 

treatment plant effluent discharge. Effluent is treated at a secondary facility onsite, and discharged into an irrigation ditch that is tributary to French Camp 

Slough. Water quality concerns associated with the implementation of the Inland 

Surface Water Plan prompted the Regional Water Quality Control Board to 

require an ERWQA as a condition in the plant's Waste Discharge Requirements. 

Based on a limited number of lab tests, a work plan was prepared for the ERWQA 

to assess the impact of continued effluent discharges on the receiving water and 

possibly lead to treatment process and/or operational modifications.

 Sacramento Municipal Utilities District Phase I and II Environmental 

Assessments. Performed Phase I and Phase II environmental site assessments on 

two cogeneration plant sites. The assessments consisted of records searches, 

interviews with representatives from regulatory agencies, field reconnaissance, 

sampling of surface soils, laboratory testing, and analysis of data. The 

assessments resulted in recommendations regarding the need for additional 

subsurface investigations and the risks associated with disposing of soil from the 

sites. 

 City of Willits Sanitary Survey, Mendocino County. Managed the preparation 

of a watershed sanitary survey for the City Water Department for submission to 

the Department of Health Services to comply with the California Surface Water 

Treatment Regulation. In accordance with AWWA guidelines, the survey 

identifies potential contaminant sources within the watershed, and suggests 

methods for effectively managing the watershed. Potential contaminant sources 

within the 3,200-acre watershed include septic systems, mining, and a police 

shooting range. 

 Carmichael Water District Bajamont Way Phase I Environmental Site 

Assessment and Disposal Area Preliminary Assessment. Performed a Phase 1 

environmental assessment on the District's Corporation Yard site. The assessment 

consisted of a records search, interviews with representatives from regulatory 

agencies, field reconnaissance, sampling of surface soils, laboratory testing, and 

analysis of data. The assessment resulted in recommendations regarding the need 

for additional subsurface investigations and the risks associated with disposing of 

soil from the site. A preliminary assessment of a spoils disposal area at the site 

was also performed. 

 City of San Leandro Groundwater Monitoring Program. Developed and 

implemented a groundwater monitoring program for the City's Dredged Material 

Management Site, adjacent to San Francisco Bay. The site is used to dewater 

dredged material from the City's marina prior to land disposal. As a condition of 

the City's NPDES permit, ESA developed and implemented a groundwater 

investigation that included the installation and quarterly sampling of six 

monitoring wells. Four quarterly reports were prepared and submitted to the 

Regional Water Quality Control Board.

 Auto Park Treatment Tank Relocation Engineering, Environmental Review, 

and Land Acquisition. Relocated Calgon activated carbon adsorption system, 

consisting of two tanks each with 20,000 pounds of granular activated carbon. 

Project included installing water and sewer pipelines, booster pump station, and 

electronic controls, so as to allow continued use of a 1,000+ gpm well. The 

treatment system had been temporarily sited as an emergency measure to treat 

PCE contamination discovered in water from an existing well. Community 

concerns about visual impacts necessitated relocation.

 Strasbaugh Well Nitrate Treatment Engineering Studies. Studied the 

feasibility of providing nitrate removal for a contaminated groundwater source. 

Proven groundwater supplies were unusable because of nitrate contamination in 

the area. The contamination was the result of decades of intensive agricultural 

activity. An ion exchange process designed to remove nitrates from well water, 

and supporting infrastructure, was evaluated. 

 American I Cogeneration Facility Spill Prevention Control and 

Countermeasure Plan. In cooperation with Sage Environmental, prepared a 

SPCCP for a cogeneration facility in King City. The American I facility uses a 

gas turbine cogeneration unit to generate electricity and provide steam and hot 

water to a neighboring food processing plant. Because of the large quantities of 

fuels and other chemicals stored at the facility, a SPCCP was required by the 

Regional Water Quality Control Board (RWQCB). In requiring the SPCCP, the 

RWQCB was implementing the regulations contained in Title 40 of the Code of 

Federal Regulations, Part 112. The SPCCP consists of an inventory of storage 

tanks and containment systems at the facility and recommendations to prevent 

hazardous materials from being released into nearby surface waters. 

 Defense Distribution Region West Sharpe Depot Storm Water Pollution 

Prevention Plan, Lathrop, California. Under contract to the US Army Corps of 

Engineers, prepared a SWPPP for the 300 acre Sharpe Depot. The depot receives, 

warehouses, and ships out military supplies and equipment. Shipments of bulk 

chemicals, mechanical parts, weapons, ammunition, and supplies arrive at the 

depot by air, rail, and truck. Previous spills at the depot have caused groundwater 

contamination and required remedial actions. To comply with Regional Water 

Quality Control Board NPDES permit requirements, a SWPPP was prepared that 

inventoried possible sources of stormwater pollution, and recommended measures 

to prevent those pollutants from entering storm water.

1.0 INTRODUCTION 

1.1 BACKGROUND

The Lytton Rancheria of California (hereafter, “Tribe”) has submitted an application to the Bureau of 

Indian Affairs (BIA) for the subject parcels noted below to be placed into federal trust (Proposed Action). 

Once in trust, the Tribe proposes to develop a portion of the project site for residential housing and Tribal 

government facilities as detailed in the Final Environmental Assessment (EA) (AES, 2011). Alternatives 

B and C include an onsite wastewater treatment and reclamation facility (WTRF) landscaping areas for 

recycled water irrigation during the year. Alternative B has two options: under the first option, 

Alternative B would involve on-site tertiary treatment and seasonal reclamation with surface water 

discharge when permitted (October 1-May 14), or when waste discharge flows is greater than one percent 

of the receiving stream’s flow. The second option for Alternative B involves complete on-site tertiary 

treatment and reclamation. The first option for Alternative B includes the onsite WTRF and 

approximately 11.75 acres of landscaped or other area for recycled water irrigation (spray fields) during 

summer months (May 15-September 30) or when surface water discharge is not feasible. Treated water 

would otherwise be disposed of via discharge to one of two drainages. The second option under 

Alternative B also involves construction of the WTRF for year-round reclamation and approximately 42.1 

acres of landscaped or other area for year-round recycled water irrigation would be required. 

As described in the Final EA (AES, 2011), two locations for the potential onsite WTRFs are available if 

Alternative B or C is chosen. Proposed WTRF location #1 is situated in northwestern corner of the 

project site, while WTRF location #2 is situated in the southeastern corner of the project site. Location #1 

would discharge tertiary treated effluent (after onsite use is maximized) into an unnamed drainage 

channel that connects to a roadside drainage channel along Windsor River Road. This roadside channel 

follows Eastside Road south for approximately 1,000 feet prior to flowing west into an abandoned quarry 

adjacent to the Russian River. This quarry pit has a small surficial connection to the Russian River. 

Location #2 would discharge tertiary treated effluent (after onsite use is maximized) directly into an 

unnamed stream tributary to Windsor Creek, which is a tributary to Mark West Creek thence the Russian 

River. If Alternative A is implemented, the Tribe will connect to the Town of Windsor’s municipal 

system. Currently the Town of Windsor operates a wastewater treatment facility and discharges advanced 

treated effluent directly into Mark West Creek under NPDES No. CA0023345 (NCRWQCB Order No. 

R1-2007-0013). 

1.2 PURPOSE OF STUDY

Either of the proposed discharges would ultimately require a National Pollutant Discharge Elimination 

System (NPDES) permit issued by the U.S. Environmental Protection Agency (USEPA) under section 

402 of the federal Clean Water Act (CWA). The purpose of this study is to provide a description of 

biological resources, beneficial uses and water quality objectives within the proposed receiving water 

bodies, and an analysis of the impacts of the proposed discharge. To fulfill this purpose, this assessment 

presents information on the existing hydrology, water quality, habitats, and biota within the unnamed 
Stream Characterization Report 

Analytical Environmental Services 2 Lytton Residential Development 

October 2010 Stream Characterization 

streams, Windsor Creek, Mark West Creek and the Russian River. Conclusions are drawn regarding the 

potential effects of the proposed wastewater effluent discharge on water resources, biological resources, 

and beneficial uses within these receiving water bodies. 

1.3 PREVIOUS STUDIES

Several recent studies and environmental reviews have been conducted for the project site and the 

receiving water bodies downstream of the proposed discharge locations, including: 

• Draft Environmental Assessment, Lytton Residential Development (AES, 2009); 

• Biological Assessment, Lytton Residential Development (AES, 2010a); 

• Wetland Delineation, Lytton Residential Development (AES, 2010b); 

• Lytton Rancheria Water and Wastewater Feasibility Study (ECO:LOGIC, 2010); 

• Town of Windsor NPDES Permit, WDID#1B037OSON (USEPA, 2007); 

• Stream Maintenance Program DEIR for Sonoma County Water Agency (Horizon Water and 

Environment, 2009); and 

• U.S. Geological Survey (USGS) Water Quality Data for the Lower Russian River Basin (2006). 

1.4 PROPOSED DISCHARGE

A state-of-the-art Membrane Bioreactor (MBR) treatment process will result in a quality of water 

compliant with California Title 22 tertiary treated wastewater standards. Tertiary effluent leaving a MBR 

process will have the appearance of potable water. Proposed average daily flow from the Tribe’s WTRF 

is 63,600 gallons per day (gpd) for Alternatives A and B and 24,600 gpd for Alternative C (ECO:LOGIC, 

2010). The goal for the Tribe’s discharge strategy is to minimize the volume of effluent that will be 

discharged to surface waters. To that end, effluent produced by the WTRF would be stored and used for 

water reclamation and irrigation of landscaped areas in the development. Once those disposal methods 

have been fully utilized, effluent would then be disposed of by surface discharge into either of the 

unnamed streams noted as locations #1 and #2 above. Discharge into these unnamed streams, based on 

similar permits for discharge in the Russian River Watershed, would be limited by both the time of year 

and the flow in the river (May 15 through September 30). 

2.0 PROJECT SETTING 

2.1 PROJECT LOCATION AND HYDROLOGIC SETTING

The project site is located within the Russian River Valley, west of Interstate Highway 101, east of the 

Russian River and approximately one mile west of the Town of Windsor, within unincorporated Sonoma 

County, California (Figure 1). The project site occurs within Sections 14, 15, and unsectioned areas of 

Molinos, Township 8 North, and Range 9 West, Mount Diablo Baseline and Meridian (MDBM) in the 

“Healdsburg, CA” USGS 7.5-minute topographic quadrangle (USGS, 1993) (Figure 2). The project site 

is composed of fourteen assessor parcel numbers (APNs) discussed in further detail in Table 1 below.

HYDROLOGIC SETTING

The project site is located within the Russian Watershed, Hydrologic Unit Code #18010110 (USGS, 

1978) and is bisected from north to south by the Guerneville and Mark West Hydrologic Sub Areas 

drainage break. The Guerneville sub area drains the western portion of the project site (towards WTRF 

location #1) while the Mark West sub area drains the eastern (towards location #2) (Figure 4). Within 

the Guerneville sub area onsite there is a primary ephemeral drainage which initiates flow near the center 

of the project site. This drainage conveys a major portion of the site’s overland runoff northwest into the 

roadside ditch that runs parallel to Windsor River Road. This water crosses under Eastside Road and 

continues to flow south along the roadside drainage prior to terminating in the large abandoned gravel 

quarry adjacent the Russian River located west of the project site (Figure 4).

meanders east as it slowly transitions thru a seasonal wetland then through pasture onsite. This drainage 

enters a drop inlet which connects to the storm drain system from the housing development to the north. 

This storm drainage pipe system flows directly into the unnamed stream tributary to Windsor Creek 

described for WTRF location #2. The exit point of this storm drainage system is just west of the stream 

channel, along the eastern project site boundary where two large underground concrete storm drain 

culverts empty into the unnamed stream tributary to Windsor Creek. From this point downstream the 

hydrology of the channel is significantly altered. The influence from this point source storm drainage 

which flows during heavy runoff events has evidently altered the character of the channel as indicated by 

the channel dimensions at the southern project site boundary. 

A natural hydrologic break runs north to south down the center of the project boundary. While the 

unnamed stream tributary to Windsor creek along the eastern boundary is located within the Lower 

Russian River hydrologic area (HA), the unnamed stream tributary to the Russian River located in the 

northwest corner of the project site is part of the Middle Russian River HA. Eventually, all surface waters 

onsite drain to the Russian River. The unnamed stream tributary to Windsor Creek initiates flow 

approximately three quarters of a mile north of Windsor River Road. Its confluence with Windsor Creek 

is approximately 1.75 miles from initiation, where it drops only 50 feet in elevation yielding a slope of 

less than one percent. The unnamed stream tributary to the Russian River described for WTRF location 

#1 initiates flow on the project site as an ephemeral drainage then flows into the abandoned gravel terrace 

pit across River Road, adjacent the Russian River. While this terrace pit lacks a surface connection to the 

Russian River it maintains a nexus via subsurface underflow. 

2.2 BENEFICIAL USES AND SURFACE WATER QUALITY

The proposed wastewater treatment facilities and surface water discharge points will be on trust land 

under the jurisdiction of the USEPA which will require an USEPA Region 9 issued NPDES permit. 

Although the jurisdiction and regulatory obligations fall under federal authority for this project the 

general basin plan water quality standards and beneficial use designations that have been established by 

the North Coast Regional Water Quality Control Board (NCRWQCB; Regional Water Board) are 

expected to be considered by the USEPA. The Basin Plan designates the ways in which surface waters 

are used, either directly or indirectly, by humans or inherent with ongoing environmental uses (i.e. 

fisheries). These designations are termed “beneficial uses.” Beneficial uses specific to water bodies 

within Sonoma County are identified within the Water Quality Control Plan for the North Coast (Basin 

Plan; NCRWQCB, 2007). The Basin Plan identifies beneficial uses specific to the Guerneville and Mark 

West Creek Hydrologic Sub-areas (HSAs) of the Russian River Watershed. Each beneficial use requires 

different chemical or physical criteria for its protection. Water quality objectives for a particular water 

effluent source are directed to “the most sensitive use.” The following have been designated by the 

NCRWQCB (2007) as existing beneficial uses for the Guerneville and Mark West Creek HSAs: 

• Municipal and Domestic Supply 

• Agricultural Supply

• Industrial Service Supply 

• Groundwater Recharge 

• Freshwater Replenishment

• Cold Freshwater Habitat 

• Wildlife Habitat 

• Rare, Threatened, or Endangered Species 

• Migration of Aquatic Organisms 

• Spawning, Reproduction, and/or Early Development 

• Estuarine (Guerneville Subarea only) 

The Basin Plan (NCRWQCB, 2007) also provides water quality objectives for inland surface waters for 

the North Coast Region, including the Basin. Table 2 lists the general water quality objectives by 

parameter. 

Impaired Water Bodies

Approximately 59 percent of the area of the North Coast Region, including the Russian River, is listed as 

impaired due to sediment under Section 303(d) of the federal CWA. Temperatures have also increased as 

a result of human activity, resulting primarily from removal of riparian vegetation and changes in the 

volume of water flowing within a stream on a daily basis. Section 303(d) of the CWA requires that each 

state identify those waters within its boundaries that do not meet the water quality standards that have 

been set for them. These are designated as impaired water bodies do not meet water quality standards. 

When identified, a priority schedule for the development of total maximum daily loads (TMDLs) for each 

contaminant or “stressor” impacting the water body is established. Both the Mark West Creek and 

Guerneville HSAs are listed as impaired on the most current (2006) USEPA Section 303(d) list, approved 

on June 28, 2007 (USEPA, 2006). The Mark West Creek HSA is impaired due to sedimentation/siltation 

and temperature; the TMDL is scheduled to be completed in 2019 to address these impairments (USEPA, 

2008a).

The Guerneville HSA is impaired due to pathogens, pH, sedimentation/siltation, and temperature. The 

listing for pathogens covers only the Monte Rio area of the watershed from the confluence of Dutch Bill 

Creek to the confluence of Fife Creek and Healdsburg Memorial Beach from the Hwy 101 crossing to the 

railroad crossing upstream of the beach. The listing for pH only applies to Pocket Canyon Creek, a 

tributary to the lower Russian River. The TMDL for pathogens was scheduled to be completed 

September 2008 while the TMDL for temperature, sediment and pH are scheduled to be completed by 

2019 (USEPA, 2008b). The Regional Water Board, in cooperation with researchers at the University of 

California, Davis, is studying the Russian River in order to establish a TMDL for pathogens 

(NCRWQCB, 2007). 

Wastewater Discharge Prohibitions 

In order to prevent surface waters within the Russian River watershed from becoming effluent-dominated, 

the Basin Plan provides specific limitations to the timing of effluent discharges into surface waters of the 

Russian River watershed (NCRWQCB, 2007). These waste discharge limitations are set as follows: 

“The Regional Water Board declares that point source waste discharges are prohibited in the 

following locations in the Russian River and its tributaries during the period of May 15 

through September 30 and during all other periods when the waste discharge flow is greater 

than one percent of the receiving stream's flow as set forth in NPDES permits. In addition, 

the discharge of municipal waste during October 1 through May 14 shall be of advanced 

treated wastewater in accordance with effluent limitations contained in NPDES permits for 

each affected discharger, and shall meet a median coliform level of 2.2 mpn/100 ml.” 

As stated above, discharge of wastewaters is prohibited in the Russian River Basin between May 15th and 

September 30th, and during all periods when the wastewater discharge would be greater than 1 percent of 

the stream flow of the receiving water body. The nearest active USGS gauging station (#11461000) is 

located on Mark West Creek, approximately five miles downstream of the proposed discharge location

2.3 AQUATIC HABITATS 

The project site contains a variety of aquatic habitat types. Six aquatic habitat types were identified onsite: perennial drainage, ephemeral drainage, seasonal wetland swale, seasonal wetland, wetland pit and 

mixed riparian. A summary of the aquatic habitat types identified within the project site is provided 

below. A map that illustrates these aquatic habitat types within the project site is presented as Figure 5. 

Perennial Drainage

Perennial drainages are linear features that exhibit an Ordinary High Water Mark (OHWM), have a 

clearly defined bed and bank, are typically inundated year-round, and have some degree of ground water 

contribution. A single perennial drainage was mapped within the project site for a total of 0.036 acre 

along the eastern boundary. This feature is the unnamed stream tributary to Windsor Creek and is shown 

as a blue-line stream on the “Healdsburg,” CA USGS quadrangle (USGS, 1993) (Figure 2). Mixed 

riparian habitat surrounds the perennial drainage and the density and width of this corridor varies. 

Ephemeral Drainage

Ephemeral drainages are linear features that exhibit an OHWM and usually possess a clearly defined bed 

and bank. They are seasonal features that typically convey rainwater and surface runoff flows seasonally 

and for short period. The channels within ephemeral drainages tend to be largely unvegetated due to the 

scouring effects of flowing water. If plants do occur within ephemeral drainages, they tend to occur 

within the upper limits of the drainage or in areas where sediment has deposited that can function as a 

plant substrate. Unlike intermittent drainages, ephemeral drainages are not typically influenced by 

groundwater. Nine ephemeral drainages (approximately 0.379 acre or 8,270.18 linear feet) were mapped 

within the project site (AES, 2010b). Plant species observed within the ephemeral drainages include: tall 

flat sedge (Cyperus eragrostis), pennyroyal (Mentha pulegium), poverty rush (Juncus tenuis), ryegrass

(Lolium perenne), fiddle dock (Rumex pulcher), sedge (Carex densa), torilis (Torilis arvensis), Klamath 

weed (Hypericum perforatum), and shortpod mustard (Hirschfeldia incana). 

Seasonal Wetland Swale 

Seasonal wetland swales are typically linear-shaped features that lack a clearly defined bed and bank and 

do not exhibit an OHWM. The length of inundation within seasonal wetland swales is relatively short 

and seasonal. These features primarily carry surface runoff and rainwater from areas of higher elevation 

to areas of lower elevation. Three seasonal wetland swales (approximately 0.273 acre) were mapped 

within the project site (AES, 2010b). Plant species observed within these seasonal wetland swales 

include: Valley oak (Quercus lobata), pennyroyal, tall flatsedge, ryegrass, cut-leaved geranium 

(Geranium dissectum), spiny-fruit buttercup (Ranunculus muricatus) and curly dock (Rumex crispus). 

Seasonal Wetland 

Seasonal wetlands are typically closed, depressional features that are ephemerally wet due to the 

accumulation of surface runoff and rainwater collection within low-lying areas. The length of inundation 

tends to be relatively short and seasonal wetlands are typically dominated by non-native, hydrophytic 

plant species. Seven seasonal wetlands (approximately 0.624 acre) were mapped within the project site 

(AES, 2010b). Plant species observed within the seasonal wetlands include blue oak (Quercus douglasii), 

ryegrass, fiddle dock, quaking grass, poverty rush (Juncus tenuis), hedgehog dog-tail grass (Cynosurus 

echinatus), pennyroyal, tall flatsedge, Bermuda grass (Cynodon dactylon), annual vernal grass 

(Anthoxanthum aristatum), curly dock, soft brome (Bromus hordeaceus), Mediterranean barley (Hordeum 

marinum), white water buttercup (Ranunculus aquatilis) and little quaking grass (Briza minor). 

Isolated Pit

The isolated pits within the project site are relatively deep holes that were excavated within uplands. 

These features are round to rectangular in shape and the excavated dirt is piled right beside them. Two 

isolated pits (approximately 0.022 acre) were mapped within the project site (AES, 2010b). The two 

isolated pits may have functioned as watering holes for cattle, test percolation pits, or potential sites for 

trash disposal. Creeping spikerush (Eleocharis macrostachya) was the dominant plant species observed 

within the isolated pits on-site. 

Stock Pond 

Stock ponds are typically man-made pond features which usually have a clearly defined bed and bank and 

OHWM. Two stock ponds occur within the northern two parcels of the project site, comprising 

approximately 0.266 acre. One stock pond in parcel 066-050-047 was created approximately 20 years 

ago and was observed to be isolated. This stock pond measures roughly 25 meters by 20 meters, with an 

approximate depth of one meter. The other stock pond is located to the west behind an impoundment 

dam in parcel 066-050-040 within an ephemeral drainage. This stock pond measures roughly 20 meters 

by 15 meters, with an approximate depth of one-half meter. Dominant plant species observed within the 

stock ponds include spikerush and semaphore grass (Pleuropogon californicus); rye grass and wild oats

were dominant along upland slopes. 

Mixed Riparian

Approximately 1.56 acres of mixed riparian habitat was mapped within the project site, which represents 

1.3 percent of the project site. Mixed riparian habitat occurs along several of the drainages that were 

mapped within the project site. Plant species observed in the tree layer of this community include Valley 

oak, willows (Salix sp.), and Fremont’s cottonwood (Populus fremontii). The dominant plant species 

observed within the shrub/vine layer of this community are Himalayan blackberry (Rubus discolor) and 

poison oak (Toxicodendron diversilobum). Other plant species observed within the herbaceous layer of this 

community include: ryegrass, little quaking grass, and blue wild-rye (Elymus glaucus).

3.0 SAMPLING METHODOLOGIES AND RESULTS 

To fully assess the potential for impacts to aquatic resources from the proposed discharge of tertiary 

treated effluent to inland surface waters, a detailed physical habitat assessment was conducted for the 

unnamed stream tributary to Windsor Creek as well as the unnamed drainage channel to the Russian 

River. Surface water quality data was compiled for Mark West Creek below the confluence with Windsor 

Creek to document the environmental baseline condition in the receiving water body prior to its 

confluence with the Russian River. Water quality data was also compiled for an abandoned gravel terrace 

pit, which is located approximately one mile south of the proposed receiving water body for effluent 

discharge location # 1. In addition, water quality results from a well test site on the project site are 

presented in the analysis below. 

3.1 PHYSICAL HABITAT ASSESSMENT

As part of this study a full physical habitat assessment was conducted to assess the physical habitat 

characteristics of the unnamed streams using the methods outlined in the California Water Boards Surface 

Waters Ambient Monitoring Program (SWAMP) Bioassessment Procedures (Ode, 2007). The field visits 

and assessments were conducted March 11 and 24, 2009. This assessment was conducted to characterize 

the instream and riparian habitats for the unnamed stream tributary to Windsor Creek and the unnamed 

drainage channel to the Russian River to evaluate the potential for instream aquatic habitats to support 

regionally occurring special status species. The assessment was also conducted to help evaluate the 

effects of a tertiary treated effluent discharge from the proposed WTRF. It should be noted that this 

assessment was conducted during a dry winter season, therefore all physical habitat and biological data 

that could be collected under these ambient conditions was done within the limits of the SWAMP 

bioassessment framework. 

3.1.1 METHODS

The SWAMP bioassessment protocol involves the characterization of ambient stream conditions for a 

randomly chosen section within the stream of study. The data collected with this methodology yields a 
Stream Characterization Report 

Analytical Environmental Services 16 Lytton Residential Development 

October 2010 Stream Characterization 

generalized characterization of the entire stream. The length of stream segment to be evaluated is 

determined by the average width of the stream. If the average width of the stream is 10 meters or greater, 

a 250 meter reach is used; if the average width is less than 10 meters then a standard 150 meter stream 

reach is used. Once the reaches were chosen, they were dissected into eleven transects (A-K) equally 

spaced fifteen meters apart. The upstream transect was labeled (A) whereas the downstream transect was 

labeled (K). The evaluation of multiple physical habitat factors was done at each transect. These 

physical habitat parameters included the measurement of bankfull width and depths across each transect, 

substrate composition at each depth measure (five measures of equal distance from bank to bank), percent 

embeddedness of cobble substrate (if present), evaluation of riparian vegetation class and relative cover, 

bank stability, tree canopy density, evaluation of human influence, and instream habitat complexity. For 

each inter-transect location the bankfull width, depths and substrates were also documented. 

Additionally, the stream gradient for both reaches was determined with a handheld clinometer. Detailed 

notes were taken on the riparian flora for each stream reach. 

3.1.2 RESULTS

These following results characterize the dominant physical habitat and geomorphic characters and the 

associated biotic habitats that are a result of stream processes in the unnamed streams. All instream 

measures were recorded as ambient field conditions depicted. Averages were calculated for all 

measurable attributes such as width, depth, substrate composition, cobble embeddedness, and canopy 

density to describe the baseline condition of the unnamed stream tributary to Windsor Creek. This allows 

for an evaluation of the potential for impacts to downstream resources and beneficial use designations as a 

result of the proposed effluent discharge into the unnamed stream tributaries. The unnamed drainage 

channel to the Russian River (proposed WTRF location #1) was evaluated offsite using a modified 

SWAMP methodology to document basic stream attributes and physical habitat components. 

For the unnamed stream tributary to Windsor Creek (proposed WTRF location #2), cumulative averages 

were calculated for stream width from 21 measurements taken throughout the reach at each transect and 

inter-transect location. Stream depths were averaged for each transect and inter-transect, therefore the 

average of these measurements is seen as the average stream depth for the entire reach. The average 

maximum stream depth was calculated by averaging all maximum stream depths recorded for each 

transect and inter-transect location, totaling 21 measurements. The average cobble embeddedness was 

calculated as the average of all measures taken for cobble substrates at transects and inter-transects. 

Canopy density was calculated as the average of all measures taken for the entire reach, totaling 44 

measures.

shown in Figure 6. Representative photographs of the unnamed stream tributary to Windsor Creek

locations for these pictures are noted in Figure 4. 

3.1.3 UNNAMED DRAINAGE CHANNEL TO THE RUSSIAN RIVER (LOCATION 1) 

Of the 26 cross sections analyzed for the unnamed drainage channel to the Russian River, the average 

width observed was 2.4 meters and the average maximum depth was 15 centimeters. Based on the 78 

random substrate observations along the length of the unnamed drainage, the dominant substrate noted 

was coarse gravel. Coarse gravels constituted 47 percent of the observations, while 45 percent of the 

observations were fine gravels. The other eight percent of the observations were split evenly between 

fines (< 0.06 mm) and concrete, both measured to be four percent. 

This channel predominantly flows through an established roadside ditch influenced by the ephemeral 

drainage onsite and a smaller drainage to the north that initiates across Windsor River Road. The flows in 

these respective tributaries do not get very high. The two drainages meet at the point where the onsite 

tributary enters the roadside ditch along Windsor River Road. Observations of bank stability were made 

during the survey. At the point of confluence of these two drainages, the roadside slope was noted to be 

unstable for approximately 30 meters. From the point where the flow is culverted under the residential 

driveway downstream to the Windsor River Road crossing, the roadside slope is reinforced with a 

concrete scour bank and is suitably stable from this point downstream. The channel is dominated by 

blackberry and willows along Windsor River Road and large, well-spaced valley oaks along Eastside 

Road. When it reaches the point where it flows west into the abandoned quarry, the drainage becomes 

choked with emergent wetland species and transitions into a seasonal wetland. From this point, the 

channel flows directly into the quarry parallel to the access road. Once in the quarry, these waters are 

exchanged through a small opening and underflow interactions with the Russian River. 

Overall habitat complexity in this channel is lacking. Riparian vegetation and cover is minimal due to the 

fact that the channel is maintained for road drainage. This intermittent drainage dries up in the summer 

months and conveys flow for short periods of time during the winter. The unnamed drainage has only a 

small surficial connection to the Russian River, therefore the special status fish species with potential to 

occur likely don’t occur in the drainage channel to the Russian River. The stream does not appear to 

contain the habitat suitability, surficial connection, vegetative cover, or flow duration that would support 

a significant number of commonly occurring local aquatic species. This assertion is further supported by 

the fact that no aquatic species were observed in the roadside ditch during the survey. Representative 

photos of the unnamed drainage channel to the Russian River are shown in Figure 6; photo point 

locations for these are noted in Figure 4. 

3.1.4 UNNAMED STREAM TRIBUTARY TO WINDSOR CREEK (LOCATION 2)

The total percentage of each substrate class for the entire reach of unnamed stream tributary to Windsor 

Creek was calculated by dividing the number of times that substrate was recorded by the total number of 

random observations; a total 105 random observations were made throughout unnamed stream in the

habitat assessment. Fines [<0.06 millimeters (mm)] was the most dominant substrate observed, 

composing 73 percent of the random observations; fine gravels (2-16 mm) constituted 17 percent of the 

substrate observations; woody debris (<0.03 m) constituted five percent of the substrate observations; 

sand (0.06-2 mm) comprised four percent of the observations; and two observations of coarse gravels 

constituted one percent of the observations made within the unnamed stream tributary to Windsor Creek. 

The substrates within the unnamed stream are dominated by fine sediments, as nearly three quarters of all 

observations during the survey were of fine silty loam. It should be noted that this heavy layer of fines 

was layered with detritus, and was nearly 15 centimeters deep above the native gravel bed load materials. 

These observations are indicative of a low gradient stream that has heavy input of deciduous material and 

a minimized hydraulic flushing capacity. This has created a very anoxic and narrow niche for 

macroinvertebrates, which results in low species richness. Very few invertebrates other than mosquito 

larvae were observed during the survey. No depositional sand bars were observed throughout the entire 

stream reach along the eastern site boundary. This is consistent with the soil type and the fact that no side 

scouring was observed within the channel throughout the reach. The bank stability was good and erosion 

potential was low based on vegetative cover. As noted in Table 5 below, the average stream width for 

the unnamed stream tributary to Windsor Creek is 2.0 meters. The average depth is 14 centimeters, while 

the average maximum depth was observed to be 18 centimeters. The average canopy density observed 

was 15 out of 17 possible measures, or 88 percent.

Cover classes were assessed within the unnamed stream for each habitat tier within a 10 square meter (m) 

plot centered on each transect. Relative scores (1-5) were generated on both banks at each transect for 

ground cover (<0.5 m), lower canopy (0.5-5.0 m) and upper canopy (>5.0 m) density. The results of 

riparian cover class assessment showed that the unnamed stream was dominated by trees and saplings at 

the upper canopy tier as observed on the aerial imagery. This cover class, on average, composed 10-40 

percent of the potential upper canopy space in the 10 meter assessment area for each bank. The average 

densitometry reading observed for the entire reach (averaged from 44 transect readings) was 15 out of 17, 

indicative of a dense upper canopy cover. An average of 10-40 percent cover was also observed for all 

vegetation between 0.5 and 5 meters in height along the left bank, while an average closer to 10 percent 

was observed along the right bank for this vegetative layer. Woody shrubs and saplings less than 0.5 

meters in height were moderately dense along the left bank, comprising on average 10-40 percent of the 

vegetation layer while the right bank averaged just above 10 percent density. Herbs and grasses were 

choked out by the woody shrubs layer along the left bank, representing on average 10-40 percent of the 

ground level vegetation. The right bank was much more dominant, comprising 40-75 percent of the

ground cover layer of vegetation as the grazing pasture encroaches upon the stream corridor in this area. 

The riparian canopy is well established and complex in this corridor, but the lower tiers of vegetation are 

predominantly invasive and encroaching, which lowers the vegetative habitat values. In general, the 

lower canopy was poorly established. Just downstream of transect A, the stream becomes highly choked 

with blackberry, poison oak vines, and oak branches. The dominant tree species observed in the upper 

canopy tier included valley oak, blue oak, black oak (Quercus kelloggii), and willow. A few sparse 

Eucalyptus (Eucalyptus sp.) trees were also observed. The results for instream habitat complexity showed 

that most habitat attributes such as large woody debris (>0.3 m), undercut banks, and boulders were 

completely absent from the unnamed stream; while overhanging vegetation, emergent vegetation, 

filamentous algae, and live tree roots were sparsely (<10 percent) observed in the channel. The gradient 

for the unnamed stream is less than one percent. This is too fine of a measurement for a handheld field 

clinometer; therefore slope measurements were not taken during the characterization. A topographic 

scale was used to calculate the gradient of the unnamed stream from initiation to the confluence with 

Windsor Creek (0.56 percent). 

Water quality data was not collected during this visit. However, it was noted in multiple locations along 

the reach that extremely anoxic organic decomposition of vegetative material was occurring on the 

streambed as gaseous bubbles were released while traversing through the stream. These conditions would 

limit the presence of any organisms in need of cool clear flowing water and intolerant to low dissolved 

oxygen levels such as salmonids, foothill yellow-legged frogs (Rana boylii), or certain macroinvertebrate 

species. Overall, the unnamed stream tributary to Windsor Creek lacks the variety of high quality habitats 

to support a diversity of aquatic species. Representative photos of the unnamed stream tributary to 

Windsor Creek are shown in Figure 7; photo point locations for these are noted in Figure 4. 

3.2 SURFACE WATER QUALITY

3.2.1 METHODS

A literature review of existing water quality data for Mark West Creek was conducted and data for Mark 

West Creek was compiled from the Town of Windsor’s NPDES permit (CA23345) reasonable potential 

analysis (RPA) that was used to set effluent limitations in Mark West Creek (Table 6). In addition, a 

2006 USGS Water Quality Study for the lower Russian River Basin reported water quality data for Mark 

West Creek just below the confluence with Windsor Creek (Anders et al., 2006). This USGS study also 

included water quality sampling results for a gravel terrace pit (McLaughlin Pond) approximately one 

mile south of the proposed discharge receiving body for WTRF location #1. The results from these water 

quality investigations are presented below. The locations of the USGS water quality sampling points are 

depicted in Figure 4.

Results of water quality sampling for the Town of Windsor’s NPDES permit indicate that the sampled 

contaminants were not present at levels above their respective primary maximum contaminant levels 

(MCLs), where applicable. Primary MCLs are standards outlined in Title 22 of the California Code of 

Regulations (Title 22). Primary MCLs are based on potential human health effects, are enforceable 

regulatory levels for drinking water, and have been incorporated as inland surface water quality objectives 

within the Basin Plan (NCRWQCB, 2007). Secondary MCLs are also listed in Title 22; however these 

levels are not based on human health effects, but are based on consumer taste and acceptance. 

The results of the USGS water quality study data for Mark West Creek indicate background total coliform 

levels greater than the Basin Plan water quality objective for inland surface waters designated for contact 

recreation (REC-1). As discussed above, the surface waters in the area are designated for contact 

recreation. In waters designated for contact recreation (REC-1), the median fecal coliform concentration 

based on a minimum of not less than five samples for any 30-day period shall not exceed 50/100 

milliliters (mL), nor shall more than ten percent of total samples during any 30-day period exceed 

400/100 mL (State Department of Health Services) (NCRWQCB, 2007). The standard level of coliform 

in tertiary treated effluent should not exceed a most probable number (mpn) of 2.2 per 100 mL, nor will 

the discharged effluent degrade the receiving water body beyond natural background levels reported in 

the data. All other constituents tested for were in compliance with Title 22 standards and Basin Plan 

Water Quality Objectives.

The abandoned gravel terrace pit which would be the primary receiving water body for WTRF location #1 

is located adjacent to the Russian River. While this water body has limited surficial connection to the 

Russian River, it does maintain a significant nexus due to water quality and based upon the hydrogeologic underflow equilibrium. To that effect, a USGS water quality study conducted between 2003 and 

2004 for the lower Russian River basin collected water quality samples at a similar abandoned gravel 

terrace pit approximately one mile downstream from the pit that would receive the tertiary treated effluent 

from wastewater disposal location #1 (Anders et al., 2006). The results from this study are presented in 

Table 8 below. The total coliform levels reported in this study indicate that the threshold for REC-1 was 

exceeded for this sample location for both sampling events. All other constituents tested for were in 

compliance with Title 22 standards and Basin Plan Water Quality Objectives. 

3.3 GROUNDWATER QUALITY

3.3.1 METHODS

Alternatives B and C of the Lytton Residential Development include onsite groundwater wells (AES, 

2011). Because the baseline condition of the source water depicts the treatment process prior to initial 

residential use, a water sample was collected from the test well discharge near the conclusion of the 

constant discharge pumping test and was analyzed for the physical, chemical, and radiological 

constituents regulated under Title 22 of the California Code of Regulations. The results of the 

groundwater sampling conducted for the project on December 23, 2008 are presented below in Table 9. 

The Basin Plan utilizes California Title 22 drinking water standards as the inland surface water quality 

standards (NCRWQCB, 2007). Primary standards are based on human health protection while secondary 

standards are based on consumer acceptance of taste, odor, and color and are not based on risk to human 

health. 

3.3.2 RESULTS

For Alternatives B and C, groundwater would be the primary source of water for the facilities. The 

groundwater samples that were tested contained relatively low concentrations of TDSs but exceed 

California Title 22 and Federal drinking water standards for arsenic and manganese. A water treatment 

facility will remove these constituents to make the water supply safe and potable. Thus, after initial 

treatment, the groundwater supply would not exceed California Title 22 or Federal drinking water

3.4 AQUATIC SPECIAL STATUS SPECIES

3.4.1 METHODS

The Windsor Creek and Russian River watershed was evaluated to determine habitat suitability and 

document the potential for occurrence of aquatic dependent special status species associated with these

stream courses. A database search was conducted using the California Department of Fish and Games 

(CDFG) Anadromous Fish and Habitat Data Program to determine if any anadromous fish species are 

documented to occur in the upper reaches of Windsor Creek near the unnamed stream associated with the 

project site (CDFG, 2010). The National Marine Fisheries Service (NMFS) database was also queried to 

determine special status species ranges, distributions and designations for Central Valley Evolutionary 

Significant Units (ESUs). Further, a Stream Inventory Report for Windsor Creek (CDFG, 2006) 

reporting on the habitat suitability of Windsor Creek for salmonids and other aquatic species was 

reviewed. These resources, in combination with the Biological Assessment (AES, 2010a) prepared for 

the project were used to evaluate habitat suitability and occurrence of aquatic dependent special status 

species within and downstream of the proposed discharge points for wastewater disposal locations #1 and 

#2. 

3.4.2 RESULTS

The aquatic life beneficial uses for the unnamed drainage channel to the Russian River, Windsor Creek, 

Mark West Creek and the Russian River are noted as Warm Freshwater Habitat, Cold Freshwater Habitat, 

Wildlife Habitat, Rare, Threatened, or Endangered Species, Migration of Aquatic Organisms, Spawning, 

Reproduction, and/or Early Development. Three special status salmonid species listed under the Federal 

Endangered Species Act (ESA) have the potential to use the unnamed stream tributary to Windsor Creek, 

Windsor Creek and Mark West Creek: the California Coastal fall-run Chinook salmon (Federally 

Threatened; FT) (Oncorhynchus tshawytscha), the Central California Coast coho salmon (Federally 

Endangered; FE) (Oncorhynchus kisutch) and the Central California Coast steelhead trout (FT) 

(Oncorhynchus mykiss). Of these three species, only the Central California Coast steelhead trout has been 

documented to occur in Windsor Creek. Based on the hydro-period, habitat discontinuity, and due to the 

lack of instream habitat complexity and riparian cover, the unnamed drainage channel to the Russian 

River does not have the potential to support any aquatic special status species.

Chinook Salmon

The California coastal ESU of Chinook salmon spawns in larger coastal streams from Redwood Creek in 

Humboldt County, California south to the Russian River in Sonoma County (70 FR 37160; Moyle, 2002). 

The fall-run Chinook salmon exhibits a true fall-run type migration into the Russian River which begins 

in early September and gradually declines through the end of December. Chinook are known to spawn 

predominantly in the mainstem channels of the Russian River and Dry Creek and utilize the estuary 

during their migration to and from the Pacific Ocean (NMFS, 2008). Peak spawning activity occurs from 

mid-October through late November and into early December (SCWA, 2008). Fry emergence occurs 

after approximately 50 days of incubation depending on the average stream temperature, dissolved 

oxygen concentration and aeration (Moyle, 2002). Juvenile residency typically lasts around three months 

but can be extended if cooler water temperatures are sustained through the late spring months. During 

these specified peak migration and spawning periods the flows of many of the tributaries to the mainstem 

Russian River are at base levels, allowing minimal access to even the larger perennial tributary streams. 
Stream Characterization Report 

Analytical Environmental Services 29 Lytton Residential Development 

October 2010 Stream Characterization 

Due to these hydrologic constraints, all spawning, rearing, and hence migration, occurs in either the 

mainstem Russian River and/or Dry Creek. The Chinook salmon life history strategy has specifically 

limited their habitat utilization to the larger tributary waters of Dry Creek and the main stem Russian 

River. They are not historically documented to occur in Windsor Creek. 

NMFS critical habitat has been designated for the California coastal Chinook salmon ESU September 2, 

2005 (U.S. Federal Register, 2005). The designation includes all accessible river reaches in the Russian 

River watershed. The portion of the Russian River nearest the project site is located within this NMFS 

designated critical habitat zone, yet these designations are not valid on Tribal lands owned in fee or held 

in trust. A recovery plan has not yet been completed for this species. 

Coho Salmon 

The California Coastal coho salmon displays the typical anadromous life history strategy of other Pacific 

salmonids, yet they are predominantly a true winter-run species in northern California. Coho of this ESU 

migrate out of the marine environment into their natal streams typically at three years of age. Migration 

peaks from November through January for southern ESUs while migration can start as soon as October 

for the northern ESUs. Actual spawning tends to occur during the months of January and February. 

Young coho will remain in their natal streams to rear for one to two years. These juveniles frequently 

occur in cooler tributary waters than Chinook salmon and require pristine, perennial tributary streams to 

support their long termed freshwater rearing requirements. Juveniles tend to emigrate out to the marine 

environment within approximately one year after hatching, yet two-year-old migrants are not uncommon. 

These emigrations are more dependent on threshold environmental condition than strict life history trends. 

Out migration for juvenile coho within this ESU typically peaks in April and May during high spring 

flows. 

Conrad and White (2006) conducted studies during the summers of 1992 through 2007 to determine 

presence/absence of coho salmon in tributaries to the Russian River finding that the abundance and 

distribution of coho salmon in the Russian River basin have declined precipitously in recent years 

(Conrad & White, 2006). Since 2001, wild juvenile coho presence has been confirmed in only five of the 

32 historic coho streams of the Russian River basin: Green Valley, Dutch Bill, Mark West Creek, 

Redwood Creek and Felta Creek. More recently, only three (Green Valley, Dutch Bill, and Felta creeks) 

of the 32 historic coho streams documented in the Russian River had confirmed juvenile coho salmon and 

only in intermittent years (NMFS, 2008). Nearest the project site, the Russian River Coho Salmon 

Captive Broodstock Program (RRCSCBP) has planted Young of the Year (YOY) coho from 2004 to 2008 

into Mill Creek and Palmer Creek, in addition to lower watershed tributaries such as Sheephouse Creek, 

Ward Creek, Gilliam Creek, Gray Creek, Green Valley Creek, and Dutch Bill Creek (Obedzinski et al., 

2008). The few coho salmon that remain in the Russian River watershed use the Russian River mainstem 

and estuary primarily as a migration corridor. The estuary, mainstem Russian River and Dry Creek are 

used by adult migrating coho salmon in the late fall and winter, and by smolting juveniles in the spring 

(Obedzinski et al., 2008). Some coho juveniles born in Dry Creek tributaries likely attempt to rear in Dry 
Stream Characterization Report 

Analytical Environmental Services 30 Lytton Residential Development 

October 2010 Stream Characterization 

Creek but are unable due to the high flows and lack of instream cover (Obedzinski et al., 2008). In 

general, coho currently utilize very discrete sections of the Russian River mainstem and its tributaries 

from the lower reaches of the Alexander Valley to the estuary, as supported in recent studies that illustrate 

the diminished status of the central California coho salmon in the Russian River watershed. 

The range of the Central California Coast coho ESU includes portions of Alameda, Contra Costa, Marin, 

Mendocino, Napa, San Francisco, San Mateo, Santa Clara, Santa Cruz, Solano, and Sonoma counties. 

NMFS critical habitat has been designated for the Central California Coast coho ESU, although a 

recovery plan has not yet been finalized. The Russian River hydrologic unit and Mark West sub-area are 

within the NMFS critical habitat, designated May 5, 1999 (U.S. Federal Register, 1999). 

Critical habitat is designated to include all river reaches accessible to listed coho within the range of the 

ESUs listed, excluding reaches on Tribal lands owned in fee or held in trust. Critical habitat consists of 

the water, substrate, and adjacent riparian zone of estuarine and riverine reaches in hydrologic units and 

counties identified in the Federal Register and any accessible reaches within the historical range of the 

ESUs that can still be occupied by any life stage of coho salmon. Inaccessible reaches are those above 

longstanding, naturally impassable barriers (i.e., natural waterfalls in existence for at least several 

hundred years) and specific dams within the historical range of each ESU. 

Although current NMFS sources (NMFS, 2008) show that coho salmon have historically been absent 

from Windsor Creek, the reach is still technically designated critical habitat under the ESA, as stated 

above, due to the continuity and close proximity to viable coho streams, such as Mark West Creek where 

coho are still documented to occur. 

Steelhead Trout 

The Russian River historically supported nine separate and distinct populations of steelhead in Austin 

Creek, Dutch Bill Creek, Green Valley Creek, Mark West Creek, Dry Creek, Mayacama Creek, and 

Sausal Creek (NMFS, 2008). These Central California Coastal steelhead trout migrate into the Russian 

River during the initial storm events and high pulse flows during the winter months from as early as 

November through February, thus display a true winter run life history strategy. Steelhead typically 

migrate to spawn in the most upper reach streams tributary to mainstem Russian River, in search of rich 

sources of spawning gravels. Typically, most spawning does not occur until later in the spring to avoid 

damage from high winter flows (Moyle et al., 2008). Similar to salmon, steelhead fry emergence occurs 

after about six weeks at 15° Celsius, yet warmer water temperatures in the spring can rapidly increase 

development. Juvenile residency is highly variable and can last from a few months to up to two years 

depending on environmental conditions with the most critical being temperature. Most out migrants will 

ride out high spring pulse flows into the estuary where they will smolt prior to entering the ocean 

environment. Adults will return anywhere from three to five years and unlike other salmonids can spawn 

multiple times. 
Stream Characterization Report 

Analytical Environmental Services 31 Lytton Residential Development 

October 2010 Stream Characterization 

While a majority of steelhead YOY attempt to rear in the upper watershed tributaries to the mainstem 

Russian (NMFS, 2008), the overall percentage of historical upper watershed spawning and rearing 

habitats has been cut off with the creation of Coyote Valley Dam (CVD) and Warm Springs Dam (WSD). 

Some estimates quantify that nearly 21 percent historic steelhead habitats above CVD have been lost, 

while losses above WSD are approximately 56 percent of historic habitat (NMFS, 2008). With these 

major factors taken into account the rearing strategies of Russian River steelhead are loosely understood, 

yet steelhead parr in the Russian River have been detected moving downstream towards the estuary in 

quantities sufficient to suggest that a significant portion of the Russian River populations attempt to rear 

there (in the mainstem Russian River). Throughout the Russian River mainstem juvenile steelhead occur 

in variable densities. NMFS critical habitat was designated in the Russian River basin for the Central 

California Coastal steelhead ESU, which includes Windsor Creek, on September 2, 2005 (U.S. Federal 

Register, 2005), yet as previously stated for both Chinook and Coho salmon, these critical habitat 

designations are not afforded on Tribal lands. 

4.0 DISCUSSION 

Under Alternatives B and C, it is anticipated that the project will utilize groundwater from wells onsite. 

The groundwater sample results for the well tests are presented in Table 9. This data reported two 

constituents that exceeded California Title 22 and Federal MCL standards for drinking water; magnesium 

and arsenic. Reduction of the concentration of these constituents to meet Title 22 water quality standards 

will occur to improve the quality of the potable water prior to the wastewater treatment process. Using 

the Best Available Technology (BAT) for treatment of arsenic and manganese, the water treatment plant 

will consist of a coagulation/precipitation and filtration process. The treatment residuals will require a 

sludge thickening and disposal process. For arsenic treatment, wastes are typically settled solids, the byproducts of chemical coagulation, plus iron and manganese precipitate captured during filtration. The 

backwash liquid may constitute 3 to 10 percent of the volume of raw water processed, and solids 

concentration may vary from 0.5 to 2 percent, depending on the raw water quality and volume processed. 

Residuals thickening will be included at the water treatment plant. The thickened solids would be 

transported to the wastewater treatment facilities solids handling facility for dewatering and eventual 

offsite disposal at the regional landfill (ECO:LOGIC, 2010). Therefore, treatment for arsenic and 

manganese in the initial purification process will result in the removal of these constituents as solids. 

The proposed WTRF will produce disinfected tertiary treated recycled water consistent with Title 22 

requirements. Disinfected tertiary treated water includes secondary effluent that has undergone tertiary 

treatment and has been disinfected to a level such that the median coliform bacterium in the water does 

not exceed 2.2 per 100 mL. Title 22 defines the tertiary treatment process as wastewater that has been 

oxidized, coagulated, clarified and filtered. The Title 22 approved uses for disinfected tertiary recycled 

water include the following: flushing of toilets and urinals, structural fire fighting, decorative fountains, 

parks, and landscape irrigation. This water will also meet the numerical receiving water quality 

objectives for inland surface waters as outlined in the North Coast Basin Plan for the Russian River and 
Stream Characterization Report

its tributaries (Tables 2 & 3). These standards are set to maintain that all waters are maintained free of 

toxic substances in concentrations that are toxic to, or that produce detrimental physiological responses in 

human, plant, animal, or aquatic life. 

The proposed WTRF includes a nitrogen-reduction process that would reduce the average nitrogen 

concentration in its effluent to less than 10 milligrams per liter (mg/l). Under the first option under 

alternative B, up to 11.6 million gallons (Mgal) of effluent would be applied annually to 11 acres of land 

on the project site under normal rainfall conditions. Under the second option under Alternative B, up to 

27.3 Mgal would be applied annually to 25.9 acres of land on the project site under normal rainfall 

conditions. This would result in a nitrogen application rate not exceeding 88 pounds per acre per year 

(lbs/ac/year), which is 200 to 300 lbs/acre/year less than the typical nitrogen fertilization rate for turf 

grass. Degradation of groundwater from nitrogen would not result from the use of effluent to irrigate the 

project site (ECO:LOGIC, 2010). 

While the unnamed tributary to Windsor Creek is a perennial stream course, the seasonal fluctuations in 

flow and the utilization of the available instream habitat by aquatic species is highly variable. The 

potential for aquatic species to use the unnamed stream to Windsor Creek is progressively based on water 

availability, then ambient temperature, then niche availability. During the surveys it was noted that the 

instream habitats for the unnamed stream tributary to Windsor Creek were limited. Therefore, only the 

most adapted species within this narrow range of suppressed aquatic habitat would be predicted to occur 

within the upper reaches of the unnamed stream to Windsor Creek. Based on the observations made 

during the stream assessment, this stream reach is unsuitable for Central California Coast steelhead 

spawning and rearing. While the stream reach within the project site does not contain the instream habitat 

complexity to support cold freshwater habitat for spawning, reproduction, or early development, it does 

contain the suitability for all other beneficial use designations for the Mark West HSA. 

5.0 CONCLUSION 

None of the special status fishes evaluated would be adversely affected by the proposed wastewater 

discharge as the beneficial use designation of the receiving water bodies will be maintained through high 

quality tertiary treated effluent, and limitations on seasonal discharge. The aquatic life beneficial uses for 

the unnamed drainage channel to the Russian River, Windsor Creek, Mark West Creek and the Russian 

River are noted as Warm Freshwater Habitat, Cold Freshwater Habitat, Wildlife Habitat, Rare, 

Threatened, or Endangered Species, Migration of Aquatic Organisms, Spawning, Reproduction, and/or 

Early Development. The water quality parameters such as temperature, dissolved oxygen, and pH 

requirements of the wastewater treatment plant effluent would meet the basic criteria for these designated 

beneficial uses as specified in inland surface water quality requirements of the Basin Plan (Table 2). 

The habitat quality observed in the unnamed stream tributary to Windsor Creek is minimally suited for a 

suite of regionally occurring common and sensitive freshwater species found within the Russian River 
Stream Characterization Report 

Analytical Environmental Services 33 Lytton Residential Development 

October 2010 Stream Characterization 

hydrologic unit. Several of the streams tributary to and associated with the lower Russian River have the 

potential to support special status species such as steelhead trout, Chinook salmon, and Coho salmon. 

The unnamed stream tributary to Windsor Creek was dominated by fine sediments, contained no 

substantially large substrates and lacked instream habitat complexity. It supported no diversity in flow 

regimes habitat as the gradient was below one percent while the reach was saturated by both fine and 

course particulate organic decomposing matter. This has created a very anoxic and narrow niche for 

macroinvertebrates, which results in low species richness. Very few invertebrates other than mosquito 

larvae were observed during the survey. Species richness is an indicator of relative stream health and 

niche availability, and can be the basis for a multitude of biological assumptions and hypotheses. Overall, 

the biological suitability of this stream is lacking. Additionally, there are potential water quality impacts 

to the unnamed stream from the residential development to the north. Stormwater from the residential 

development flows into the unnamed stream through the culverts shown in Figure 6. 

The unnamed drainage channel to the Russian River that extends from the northwest corner of the project 

site to the abandoned quarry is best characterized as a roadside ditch. Although this channel initiates flow 

from two ephemeral drainages (one onsite) and supports a gravel substrate base, it does not contain the 

habitat suitability, surficial connection, vegetative cover, or flow duration that would support a significant 

number of commonly occurring local aquatic species. This assertion is further supported by the fact that 

no aquatic species were observed in the roadside ditch during the survey. In addition, this drainage 

receives flashy roadside runoff during rain events, which more than likely contributes petroleum based 

hydrocarbons and other common automotive pollutants into the system. Based upon this information, no 

significant water quality effects would occur to the stream course, the gravel terrace pit receiving water 

body, or the Russian River as a result of the project. 

No adverse impacts to the designated aquatic life beneficial uses would occur as a result of a direct 

tertiary treated effluent discharge from the proposed project to either of the identified channels. The high 

level of treatment at the proposed WTRF shall maintain water quality standards as set in the Basin Plan 

and may minimize the volume of surface water discharge by utilizing other disposal methods such as 

irrigation and toilet flushing. In addition, a stream setback corridor will be established for the unnamed 

stream tributary to Windsor Creek to promote native vegetation establishment and ensure stream bank 

stabilization at the discharge point. This will increase aquatic habitat value and allow the establishment 

of vegetation which will reduce the potential for bank erosion in the discharge channel. 

While there is a potential for steelhead to utilize the downstream reaches of Windsor Creek it should 

again be noted that all wastewater will be treated to California Code of Regulations Title 22 standards and 

would meet the water quality objectives outlined in the Basin Plan for inland surface waters of the 

Russian River watershed. The volume of effluent discharged into the unnamed stream to Windsor Creek 

will be fully minimized as recycled water prior to surface water discharge. The proposed discharge will 

meet or exceed water quality standards of the Basin Plan for surface waters; therefore it will not adversely

affect the designated beneficial uses for aquatic life in the receiving water bodies, Windsor Creek, Mark 

West Creek or the Russian River.
