Abstract: This Supplemental Draft Environmental Impact Statement (SDEIS) describes seven 

alternatives, six of which propose changes to the National Forest Transportation System (NFTS) and 

would prohibit cross country travel on the Tahoe National Forest (TNF). These actions are needed in 

order to implement the 2005 Travel Management Rule (36 CFR Part 212, Subpart B) while providing for 

a diversity of motor vehicle recreation opportunities and providing motorized access to dispersed 

recreation opportunities on the TNF. The SDEIS discloses environmental impacts associated with the 

Proposed Action, a No Action Alternative and 5 additional alternatives developed to meet the purpose and 

need and to respond to issues raised by the public.

Appendix A: Site Specific Road, Trail

and Open Area Information

Introduction ____________________________________________

Appendix A displays the site specific resource information and required mitigation measures for all of the 

motorized trails proposed as additions to the National Forest Transportation System (NFTS) as well as the 

Maintenance Level 1 roads to be reopened in the alternatives. Table A-1 (next page) displays the 

following information for each proposed motorized trail to the NFTS.

The unique Route ID used throughout the document and maps for each motorized trail addition to 

the NFTS as well as Maintenance Level 1 roads to reopened.

The Current Status of each proposed motorized trail addition to the NFTS. The current status is 

one of the following 1) A Maintenance Level 1 NFTS road not currently authorized for motorized 

use, 2) A temporary road constructed as part of a vegetation management project but not intended 

for long term motorized use or 3) an Unauthorized Route by the public not authorized for 

motorized use.

The Class of Vehicle and Season of Use that would be authorized should the motorized trail be 

added to the NFTS in each respective alternative. The possible combinations of Class of Vehicle 

and Season of Use are as follows:

Cost of mitigation measures which specifies when the mitigation measures must be implemented

Monitoring Requirements should the motorized trail be added to the NFTS

These mitigation measures required do not include ongoing operation and maintenance activities, for

example, brushing, signing, cleaning and maintaining existing drainage structures, clearing debris slides, 

patrolling routes, and so forth. Mitigation measures are designed to be somewhat flexible to capture 

opportunities to implement them. The mitigation measures in the road cards describe what needs to be 

done; how the mitigations are implemented in the field will vary, depending on access to resources to 

accomplish the work. The manner in which mitigations are implemented will affect costs.

Resource Information:

§ Field Surveys - 90% green, 10% yellow. Surveys found no accelerated erosion off-route. A 300' 

segment on 5% slope has rill erosion (3" deep x 8" wide). Runoff at water break outlets and on 

slopes adjacent to the route is dispersed effectively. Vegetation or litter filters all sediment. Spring 

near route, not impacted by route. The trail’s position on the slope is relatively stable and the 

seasonal wet season restriction will mitigate adverse watershed impacts associated with this 

route.

§ Route is on WAE soils: moderately deep to deep volcanic soils.

Resource Information:

§ Field Survey - 100% green.

§ Rill erosion and sediment deposion occurs on slope adjacent to the route as a 40' segment follows 

a narrow intermitent channel. Approach to second watercourse crossing is short and gently 

sloped. At the crossing the tread shows some evidence of widening (Normal channel width is 1 

meter, at crossing channel is 11 meters wide.).

§ Route is on TBE soils: deep soils formed in glacial till deposits. Around 25% of the area has poorly 

drained soils in drainageways with alder, willow, Carex spp.,and Juncus spp. vegetation.

§ One intermittent (green) and one perennial crossing (yellow) with sediment delivery to both 

channels.

§ EMDS Model: Erosion Risk – moderately high; Water Quality Risk – low.

Mitigation Measures Required: At first crossing need to divert intermittent channel off route. The 

second crossing is a perennial crossing. The sediment at the perennial crossing is primarily tire wash 

and redistribution of fines within the channel. This crossing could use some additional gravel on both 

approaches to reduce the channel widening and sedimentation into this tributary to Haypress Creek.

Tahoe National Forest – A-615

TKN-J5. This trail comes off Castle Road. It was previously used as an access to construct a section of the 

Pacific Crest Trail. It crosses the Pacific Crest Trail and is used to access Slab Rock, which has spectacular 

views. It will eventually tie into a mountain bike trail that is under construction.

Rationale for including / 

not including route in the 

preferred alternative

Rationale: Recommended by the public during collaboration meetings prior to the NOI. No significant 

resource concerns which could not be mitigated. No significant impact on Inventoried Roadless Area 

character.

Watershed resource 

information and 

mitigation measures

Resource Information:

§ Field Survey – 72% green, 28% yellow. There is a seep near the beginning of the route. There are 

some steep slopes and gullies are present in places. Rill erosion is present and some sediment 

deposition occurs on slopes adjacent to the route. All sediment is filtered or deposited beore it 

reaches a watercourse with a scoured channel. Parking near stream and meadow could be a 

problem with increased use.

§ Route is on AQB & WEE Soils. AQB soils have shallow to moderately deep, very poorly drained

soils in drainageways and on valley floors with Carex species, Juncus species, alder, willow and 

aspen vegetation. WEE Soils have 15% poorly drained soils in drainageways with alder, willow, 

Carex species, and Juncus species vegetation.

§ There are two crossings: one perennial (green) and one intentermittent (yellow).

§ EMDS Model: Erosion Risk – moderately high; Water Quality Risk – high.

Mitigation Measures Required: Mitigate seep at beginning of route. Need to outslope eastern end. In 

steeper areas, additional waterbars should be installed to divert runoff from the route. 

Botany resource 

information and 

mitigation measures

Resource Information: The route goes through the top of Castle Valley meadow and interrupts the 

hydrology of the top of this meadow. A portion of the route has overland flow that channels water to 

Castle Creek. There is a known occurrence of the rare moss Bruchia bolanderi in Castle Creek with 

portions of the moss occurrence located about 30 feet upstream and 50 feet downstream of the route 

crossing. Users are parking vehicles adjacent to the stream/creek and reducing vegetative cover (both 

sides of the stream – uphill and downhill). There is a known occurrence of the sensitive plant –

Erigeron miser – located at the end of the route that is being impacted by motorized use. This route 

was shortened 300 feet to reduce resource impacts to E. miser. There is a seep/spring at the 

beginning of the route that is being impacted by motorized use. Water is flowing from this seep down 

the system route and TKN-J5 although the water flow does not reach Castle Creek. Further up the 

system route – road #80-50 – water is flowing from the adjacent wetland – down the route. This is also 

adding to the cumulative impacts to Castle Valley meadow.

Mitigation Measures Required: Redirect water flow from the seep/spring at the beginning of the route 

and from overland flow down a portion of the route to Castle Creek – to the meadow. Place barriers 

and signs in the areas adjacent to Castle Creek to keep users from reducing vegetative cover adjacent 

to Castle Creek. Place barriers so that turn arounds, dispersed recreation, and parking do not occur 

within 100 feet of Castle Creek to reduce impacts to the Bruchia bolanderi occurrence. Ensure that the 

crossing of Castle Creek is not widened during high flows to reduce impacts to the rare moss –

Bruchia bolanderi - field check the route annually.

Resource Information: The route is seasonally inundated by Prosser Reservoir. As the level of the 

reservoir drops, the route is exposed in the summer dry season. The area around Prosser Reservoir in 

the location of TKN_RR is mapped as Martis-Euer Variant complex, 2 to 5 percent slopes. The tread of 

the route is actually an old railroad grade, and therefore the mapped soil characteristics are less relevant .

The railroad grade functions to keep the route elevated above the reservoir soil surface and to protect the 

soil from erosion.

Resource Information:

§ Field Survey - 100% green.

§ Route accesses a campsite 100’ above a small lake. There are five short spurs in area. Soil in 

area is very gravelly and cobbly. There is some soil movement on the route in places but, no 

accelerated erosion off-route. A 30' segment leading to campsite has minor sheet erosion and is 

naturally very cobbly. Runoff at waterbreak outlets and on slopes adjacent to the route is 

dispersed effectively. All sediment is filtered by vegetation or litter.

§ Route is on GRG, RSE, RPE soils: Granitic rock outcrops mixed moderately deep soils formed on 

glacial till and outwash primarily of volcanic origin. 15% of the area has shallow to moderately 

deep, very poorly drained soils in drainageways and on valley floors with Carex spp., Juncus spp., 

alder, willow and aspen vegetation. Shallow and moderately deep volcanic soils are also present.

§ EMDS Model: Erosion Risk – high; Water Quality Risk – moderately low.

§ No stream crossings. Route crosses several draws above the scoured channel.

Mitigation Measures Required:

§ Old vehicle parts in creek need to be removed.

§ Close spurs. Water bars needed at bottom of Section 4.

Botany resource 

information and 

mitigation measures

Resource Information: This is a series of spurs off the Fordyce trail. In the Eagle Lakes area, there 

are many spurs. One of the spurs goes to the lake edge. Users are shoting into the lake as evidenced 

by the large amount of shell casings on the granite outcrop above the lake. The sensitive plant 

Erigeron miser was detected along the YRS-F1 spur near the Fordyce crossing. Motorized vehicles 

provide the access for the foot traffic that is impacting this sensitive plant (located between the camp 

site and the creek). Near Carlisle Mine, YRS-F1 is located within 15 feet of Fordyce Creek toward the 

end of the route. YRS-F1 near the waterfall site has extremely steep access that ends at a tree (that is 

getting very scraped up). The YRS-F1 in section 34 has numerouse campsites with much evidence of 

users driving around on the granite boulders. No rare plants or weeds were found at any of these sites.

while consistently reducing sedimentation, and facilitating seed 

germination and seedling establishment.

Deferred Maintenance Maintenance that was not performed when it should have been or when it 

was scheduled and which, therefore, was put off or delayed for a future 

period. When allowed to accumulate without limits or consideration of 

useful life, deferred maintenance leads to deterioration of performance, 

increased costs to repair, and decrease in asset value. Deferred 

maintenance needs may be categorized as critical or non-critical at any 

point in time. Continued deferral of non-critical maintenance will normally 

result in an increase in critical deferred maintenance. Code compliance 

(e.g. life safety, ADA, OSHA, environmental, etc.), Forest Plan Direction, 

Best Management Practices, Biological Evaluations other regulatory or 

Executive Order compliance requirements, or applicable standards not met 

on schedule are considered deferred maintenance (Financial Health -

Service at the regional level and is not part of the designation of threatened 

or endangered species made by the U.S. Fish And Wildlife Service.

Seral Stage The stage of succession of a plant or animal community that is transitional. 

If left alone, the seral stage will give way to another plant or animal 

community that represents a further stage of succession.

Short-Term Risk A risk to be experienced within the next 10 to 15 years. For example, 

prescribed burns can disturb habitat in the short-term, but in the long-term 

the fire resiliency of the habitat may be improved.

Silvicultural System The cultivation of forests; the result is a forest of a distinct form. 

Silvicultural systems are classified according to harvest and regeneration 

methods and the type of forest that results.

Silviculture The art and science that promotes the growth of single trees and the forest 

as a biological unit.

SMOG A combination of smoke and other particulates, ozone, hydrocarbons, 

nitrogen oxides and other chemically reactive compounds which under 

certain conditions of weather and sunlight may result in a murky brown 

haze. The primary source of smog in California is motor vehicles. 

Snag A standing dead tree. Snags are important as habitat for a variety of 

wildlife species and their prey.

Spatial Analysis See Spatial Data.

Spatial Data A GIS contains spatial data. The spatial data represents geographic 

features associated with real-world locations. 

Species A class of individuals having common attributes and designated by a 

common name; a category of biological classification ranking immediately 

below the genus or subgenus; comprising related organisms or populations 

potentially capable of interbreeding.

SPLAT Strategically Placed Local Area Treatment. A system of mosaic patch 

treatments of forest or shrub vegetation designed and treated to reduce fire 

spread, intensity, and create barriers to fire spread.

Stand A group of trees that occupies a specific area and is similar in species, age, 

and condition.

Standards and 

Guidelines (S&Gs)

The primary instructions for land managers. Standards address mandatory 

actions, while guidelines are recommended actions necessary to a land 

management decision.

Stand-Replacing Fire A fire that burns with sufficient intensity to kill the majority of living 

vegetation over a given area (grass and brush fires are stand replacement 

fires for that vegetation type, in forest vegetation types when 75- 80% of 

the stand is killed by fire are also considered stand replacement fires).

Stewardship Caring for the land and its resources in order to pass healthy ecosystems 

on to future generations.

Suitability The appropriateness of certain resource management to an area of land. 

Suitability can be determined by environmental and economic analysis of 

management practices.

Sulfur oxides (SOx) Pungent colorless gases formed primarily by the combustion of sulfur 

containing fossil fuels, especially coal and oil. Considered a major air 

pollutant.

Traffic Management 

Strategies

These strategies are: encourage, accept, discourage, eliminate, and 

prohibit. The ‘encourage’ strategy directs forest visitors to important 

destinations via desirable routes. The discourage strategy informs potential 

users of road conditions that may detract from the experience they seek 

when visiting a national forest. The ‘eliminate’ and prohibit strategies are 

used to close roads with physical barriers or regulatory signs and orders 

(USDA Forest Service, Forest Service Handbook 7709.59-25.31).

configuration sufficient to protect the inherent characteristics associated 

with its roadless condition. Unroaded areas do not overlap with 

inventoried roadless areas.

Visual Quality The forest visual resources; terrain, geological features, or vegetation.

Watershed The entire region drained by a waterway, lake, or reservoir. More 

specifically, a watershed is an area of land above a given point on a stream 

that contributes water to the streamflows at that point.

Appendix F: Watershed Analysis

Introduction ____________________________________________

The purpose of Appendix F is to provide a technical overview of the analysis process and models used.

Due to the complexity and magnitude of this project, a number of analytical models and techniques were 

utilized requiring development of a decision support system to integrate these processes.

Within the Tahoe National Forest (TNF) boundary, watersheds have been designated into hydrologic 

unit code 6 (HUC6) watersheds with area (acres) designated as TNF or other. Total HUC6 area and the 

percent area on TNF are defined. Table F-2 shows the existing and proposed route miles, crossings, and 

Riparian Conservation Area miles by HUC 6 watershed and by Alternative. Per classified route, route 

distance (miles) on National Forest System lands and private lands is defined and route density defined 

(miles route/square mile) as a sum of density on forest service lands and density on private lands. Stream 

crossings are quantified as perennial and intermittent and designated as crossing through private or TNF 

land. Table F-1 shows the Codes used to indicate the class of vehicle and season use for the routes. For 

each HUC6 watershed the total acres, route distance, route density (miles per square mile), number of 

stream crossings, and density of stream crossings (number of crossings per square mile) are displayed.

Route distances within Riparian Conservation Areas are also compiled by HUC6. This data is then 

presented to include only native surface roads and motorized trails classified as “Higher Risk Routes.”

The riparian conservation area (H6 aquatic area or RCA) is defined as an area (acres) 300 feet on 

either side of perennial streams and 150 feet on either side of intermittent streams. The RCA is designated 

by route distance and density on FS and private lands. Total density is calculated per classified route and 

total distance of all routes in the H6 aquatic area is calculated on FS and private lands. This data is then 

presented to include only routes classified as “Higher Risk Routes” (native surface roads and motorized 

trails).

Stream crossings (on TNF) proposed for alternatives for each HUC6 are quantified (total TNF stream 

crossings (TNF perennial crossings, TNF intermittent crossings)) by alternative. Figure F-1 shows the 

location of each HUC6 Watersheds on the TNF. Table F-3 displays the HUC6 watershed name and 

number.

USFS REGION 5 Best Management Practices for OHV use and road construction and maintenance (from 

Regional Water Quality Management Plan, 2000)

These BMPs would apply to routes within the National Forest Transportation System.

7. Water Quality Monitoring of Off-Highway Vehicle (OHV) Use 

According To a Developed Plan (Practice: 4-7)

a. Objective: To provide a systematic process to determine when and to what extent OHV use will 

cause, or is causing adverse effects on water quality.

b. Explanation: Each Forest’s OHV plan will:

1)Identify areas, or routes where OHV use could cause degradation of water quality.

2)Establish baseline water quality data for normal conditions as a basis from which to measure 

change.

3)Identify water quality standards and the amount of change acceptable.

4)Establish monitoring methods and frequency.

5)Identify controls and mitigation appropriate in management of OHV’s.

6)Restrict OHV use to designated routes.

c. Implementation: Monitoring results are evaluated against the OHV plan objectives for water 

quality and the LRMP objectives for the area. These results are documented, along with the 

actions necessary to correct identified problems.

If considerable adverse effects are occurring, or are likely to occur, immediate corrective action 

will be taken. Corrective actions may include, but are not limited to, reduction in the amount of 

ORV use, signing, or barriers to redistribute use, partial closure of areas, rotation of use on 

areas, closure to causative vehicle type(s), or total closure, and structural solutions, such as 

culverts and bridges.

Closure is accomplished through authority of the Forest Supervisor.

12.2 - Synopsis for Road and Building Site Construction ______

NFS road planning, construction, reconstruction, maintenance and/or removal is a complex process. The 

process involves roads analysis, Access and Travel Management Planning as well as NEPA procedures. 

Though complex, it assures roads are located, designed and maintained to meet Forest management 

objectives. General objectives are set by legislation, policy, directives, and Forest and District plans.

Project-specific resource objectives and alternatives will be formulated by an IDT selected and 

convened by the line officer responsible for the road or building activity. Team members represent as 

needed; timber, engineering, geology, archaeology, land right-of-way or easements, hydrology, soil 

science, botany, landscape architecture, recreation, fisheries, wildlife, range, fire, fuels and minerals.

Most of the NFS roads in California were built under the timber harvest program as a requirement of 

the TSC. Other roads were constructed under Public Works Contracts for range, recreation, fire, or 

silvicultural purposes, or under special use purpose they serve.

Transportation planning is normally conducted on a Forest-wide basis with the objective of locating 

roads both to service the individual timber sale areas and to meet a Forest’s other long-range 

transportation needs. Road reconnaissance personnel flag proposed road corridors on-the-ground using 

road management objectives, the Forest Transportation Plan, topographic maps, aerial photographs, and 

any preliminary soils, logging, engineering, or geology data.

These corridors are reviewed by an IDT. Modifications in design and/or alignment, or new alternative 

corridors are proposed based on multiple resource management objectives, and recommendations are 

made for road design criteria. Existing roads that are to be improved or removed go through the same 

interdisciplinary review. Inadequate roads that are retained as part of the transportation system are 

upgraded to current LRMP standards and guidelines to reduce adverse environmental effects and improve 

user safety.

Interdisciplinary team roads analysis information and recommendations, along with an economic 

analysis of alternatives, are used to generate a transportation study report. The report is used to help 

assess the environmental effects and costs of roads for each alternative in the resource project 

environmental documentation.

Once an alternative has been chosen through the NEPA process, work begins on the road survey. The 

transportation study report is used to establish design criteria from which a transportation engineer selects 

road design standards. The road design standards selected depend on the type and amount of traffic, 

topography, geology, soils, requirements of the environmental document and the Access Travel 

Management Plan. Most new roads today, however, are only short segments constructed for local access 

needs. 

Engineers design the road according to the selected design standards, which may include, but are not 

limited to, road widths, road drainage, maximum road grades, radii, and road surfacing. Members of the 

IDT are usually involved in the road design phase, to assist in meeting the selected resource objectives.

Road planning and implementation includes road design, construction staking and construction 

inspection. Road design includes selection of construction specifications, which help protect

Appendix F: Watershed Analysis

environmental concerns addressed in the environmental document and preparation of the construction 

contract. Road design and construction use Forest Service Standard Specifications for Roads and Bridges, 

Special Project Specifications, Timber Sale B and C provisions, General Provisions and applicable 

American association of State Highway and Transportation Officials (AASHTO) and American Society 

for Testing and Materials (ASTM) specifications.

While road construction is in progress, the Engineering Representative (ER), Contracting Officers 

Representatives (COR), SA, FSR and Construction Inspector (CI), are frequently on the project site.

These inspectors, along with a purchaser’s or contractor’s field representative, assure that the project is 

carried out according to the specifications in the contract. Various IDT members will be called upon to 

review proposed design modifications during construction.

As part of the project plan, road management objectives are developed which detail the level of 

maintenance for each road. There are five levels of maintenance for permanent roads varying from Level 

1 (custodial care of the road and assuring functional road drainage) to Level 5 (the maintenance of two 

lane, paved roads). Maintenance generally consists of, but is not limited to, cleaning, ditches and culverts, 

road surface grading, pothole patching and surface replacement.

Closed system roads (Level 1) are barricaded to preclude use for a year or longer. Water bars are 

installed where necessary. All open permanent roads will be inspected periodically and maintained as 

needed. Temporary roads are built for short-term use, principally under a TSC or for emergency wildfire 

access. When the temporary road is no longer needed, temporary drainage structures are removed, and the 

roads are decommissioned as required by the provisions of the applicable contract.

Environmental documents based on the work of IDT are also prepared for proposed building sites.

Facilities normally encountered on National Forests are administrative sites, such as fire stations, work 

centers, ranger stations, campgrounds or VIS centers. Other proposals come from the private sector to 

build such facilities as: ski areas, marinas, concession building, waste disposal areas or access to private 

land inholdings.

Facility locations will be evaluated in much the same way as timber sale areas. An IDT is formed to 

develop resource objectives, formulate alternatives, and analyze the various sites for environmental 

effects. The IDT prepares environmental analysis, recommends alternatives, design criteria, and 

mitigation measures to meet Forest resource objectives at each site.

12.22 - Road and Building Site Construction

Best Management Practices ______________________________

The following are the BMPs for the control of non-point source pollution associated with road and 

building site construction activities. Each BMP was formulated based on the administrative directives that 

guide and direct the Forest Services’ construction and maintenance of roads, buildings, and administrative 

facilities on NFS land.

The line officer on each administrative subunit is responsible for fully implementing the directives 

that require water quality protection and improvement during road and facilities construction and 

maintenance. The directives referenced in Section 13, provide details on methods to incorporate water 

quality controls into each phase of the road and facility construction and maintenance program. The 

BMPs synthesize the direction into a “process” to be followed.

Trained and qualified earth scientists, and other professional employees, are available to provide the 

engineering work force with technical assistance to identify beneficial uses and the most recent state-ofthe-art water quality control methods and techniques; and to evaluate results. Publications and training 

sessions provide road construction and maintenance engineers with knowledge of the latest proven water 

quality protection methods.

1. General Guidelines for the Location and Design of Roads

(Practice: 2-1)

a. Objective: To locate and design roads with minimal resource damage.

b. Explanation: The following are some general considerations, which must be incorporated into 

the planning process of road location and design. These measures are preventive, apply to all 

transportation activities, and indirectly protect water quality.

1) A basic requirement for transportation facility development and operation is the formulation 

and evaluation of alternatives that will best meet the resource management objectives with the 

least adverse effect on environmental values.

2)The location, design, and construction of roads include the use of IDTs. These teams include 

professional personnel with skills in road, resources and water quality management. The team 

evaluates the effects of road system development or modification proposals on the 

environment, and formulates alternative.

3) All resource-coordinating instructions for the protection and prevention of damage to NFS 

lands, resources, and ecological systems, including wetlands and floodplains will apply to the 

planning, development, and operation of transportation facilities. The following instructions 

apply to permanent roads:

a) Locate roads to complete the area transportation system, to fit the terrain, and to minimize 

damage to improvements and resources. Avoid sensitive areas such as wetlands, inner 

gorges and unstable ground to the extent practical.

b) Base road design standards on design criteria such as traffic requirements of a timber sale, 

or the overall transportation plan, road management objectives or resource objectives, and 

minimize the effects on Forest resources including water quality.

c) Design stream crossing structures to provide the most cost efficient drainage facility 

consistent with resource protection, facility needs, and legal obligations. The design 

involves a hydrologic analysis to determine runoff volumes, flood conditions, velocities, 

scour, and open channel shapes. An economic comparison of various flood frequencies 

versus structure sizes and types is also done to meet resource and legal requirements and 

cost/benefit comparisons. All crossings will be designed to provide for unobstructed flows 

and fish passage, and to minimize diversion potential and alteration of stream channels.

c. Implementation: The IDT is selected by the line officer to assist in locating the road to best fit 

resource objectives, and to develop detailed mitigation measures. For force account projects, 

Forest engineers will be responsible for developing and meeting design specifications.

For some timber sales awarded to small businesses, the purchaser may request that the Forest 

Service construct the roads. Under present guidelines, such work is normally done by contracting 

with a road construction contractor.

The COR, ER or FSR ensures compliance with project plan requirements and the operating plan.
Motorized Travel Management Supplemental Draft Environmental Impact Statement – February 2010

Appendix F: Watershed Analysis

Tahoe National Forest – F-29

2. Erosion Control Plan (Practice: 2-2)

a. Objective: To limit and mitigate erosion and sedimentation through effective planning prior to 

initiation of construction activities and through effective contract administration during 

construction.

b. Explanation: Land disturbing activities can result in short term erosion. By effectively planning 

for erosion control, sedimentation can be controlled or prevented. Within a specified period after 

award of a contract (presently 60 days prior to the first operating season in Timber Sale 

Contracts, per C6.3) the purchaser will submit a general plan which, among other things, sets 

forth erosion control measures. Operations cannot begin until the Forest Service has given 

written approval of the plan. The plan recognizes the mitigation required in the contract. A 

similar plan is required of miners and special use permittees.

c. Implementation: Design engineers develop detailed mitigation using an IDT. The detailed 

mitigations are reflected in the contract specifications and provisions. The intent of mitigation is 

to prevent construction-generated erosion, as well as that generated from the completed road, 

from entering watercourses. Contracted projects are implemented by the contractor or operator.

Compliance with contract specifications and operating plans is ensured by the COR, ER, or FSR 

through inspection.

This practice is commonly applied to all road construction through contract clauses and 

specifications and will apply to road construction for timber sales, mining, recreation, special 

uses and other roadwork on NFS lands.
Motorized Travel Management Supplemental Draft Environmental Impact Statement – February 2010

Appendix F: Watershed Analysis

F-30 – Tahoe National Forest

3. Timing of Construction Activities (Practice: 2-3)

a. Objective: To minimize erosion by conducting operations during minimal runoff periods.

b. Explanation: The amount of erosion and sedimentation from road construction are affected by 

the magnitude of water runoff. An essential element of effective erosion control is to schedule 

operations during the dry season or when rain and runoff are unlikely. Purchasers will be 

required to schedule and conduct operations during the dry season or when rain and runoff are 

unlikely. Purchasers will be required to schedule and conduct operations to minimize erosion and 

sedimentation. Equipment will not be allowed to operate when ground conditions are such that 

excessive rutting and soil compaction could result. Such conditions will be identified by the 

COR or ER with the assistance of an earth scientist or other specialists as needed.

Erosion control work will be kept as current as practicable on active road construction projects.

Construction of drainage facilities and performance of other contract work to control erosion and 

sedimentation will be required in conjunction with earthwork projects. The operator should limit 

the amount of area being graded at a site at any one time, and should minimize the time that an 

area is laid bare. Erosion control work must be kept current when road construction occurs 

outside of the normal operating season.

c. Implementation: Detailed mitigations developed by design engineers and an IDT will be 

included in the environmental analysis and in subsequent project plans and contracts.

Project crew leaders and supervisors will be responsible for implementing force account 

projects to construction specifications and as specified in the project plan. Contracted projects 

are implemented by the contractor, or operator. Compliance with plans, specifications, and the 

operating plan will be achieved by the COR or ER through inspection.

4. Stabilization of Road Slope Surfaces and Spoil Disposal Areas 

(Practice: 2-4)

a. Objective: To minimize erosion from exposed cut slopes, fill slopes, and spoil disposal areas.

b. Explanation: This is a preventive practice using bioengineering and other techniques to prevent 

or minimize erosion. Depending on site factors such as slope angle, soil type, climate, and 

proximity to waterways, many fill slopes, some cut slopes, and some spoil disposal areas will 

require vegetative and/or mechanical measures to provide surface soil stability. The level of 

stabilization effort needed is determined on a case-by-case basis by trained and qualified 

employees.

Revegetation includes the seeding of plant species grass, legumes, or browse species--or the 

planting of brush, or trees. Revegetation may also include fertilizer, soil amendments, and 

mulching or even watering to ensure success. A combination of plant types with both woody root 

systems and fibrous root systems usually produce better results than a single plant type such as 

grass. Native species are preferred and used wherever feasible. Where local native seed is not 

available, not economically feasible or native plants would be ineffective in controlling erosion 

sterilized grass or cereal grain seed is applied. 

Mechanical measures may include, but are not limited to: wattles, erosion nets, terraces, side 

drains, blankets, mats, riprapping, mulch, tackifiers, pavement, soil seals, and windrowing 

construction slash at the toe of fill slopes.

c. Implementation: Vegetative measures are generally a supplementary device, used to improve 

the effectiveness of mechanical measures, but can be effective and complete by themselves.

They may not take effect for several seasons, depending on the timing of project completion in 

relation to the growing season.

Mechanical and vegetative surface stabilization measures will be periodically inspected to 

determine effectiveness. In some cases, additional work will be needed to ensure that the

vegetative and/or mechanical surface stabilization measures continue to function as intended.

Initial project location, mitigation measures and management requirements are developed 

during the environmental analysis process. These are translated into project plans, contract 

provisions and specifications.

Project road inspectors and their supervisors monitor work accomplishment and effectiveness, 

to ensure that design standards, project plan management requirements, and mitigation 

measures are met.

F-32 – Tahoe National Forest

5. Road Slope Stabilization Construction Practices (Practice: 2-5)

a. Objective: To reduce sedimentation by minimizing erosion from road slopes and slope failure 

along roads.

b. Explanation: This is an administrative and construction practice. It is prohibitively expensive to 

immediately and completely prevent erosion from road cut and fill slopes. However, plan all 

road construction considering adequate stabilization needs. The first planning requirement is an 

adequate soils and geologic investigation, to provide data necessary for proper cut and fill design 

such as:

1)The correct cut and fill slope steepness according to the stable angle of repose for the type of 

material.

2)Methods to handle surface and subsurface runoff.

3) Necessary compaction standards and surfacing needs.

A prerequisite for stabilization is to provide basic mechanical stability of the soils, using data 

from soils and geologic investigations to develop requirements for proper slope angles, 

compaction, and adequate drainage.

c. Implementation: Include erosion prevention considerations in planning for all road 

construction contracts. Application is commonly in conjunction with practice 2-4.

Complete most, if not all, of the stabilization measures prior to the first winter rains. At 

especially critical locations, with a high erosion and/or sedimentation potential, extensive and 

reliable remedies will be necessary. Determine a project location and detailed mitigation 

measures during the environmental analysis and included them in the project plan.

Project crew leaders and supervisors will be responsible for ensuring that force account projects 

meet design standards and project criteria. Contracted projects are implemented by the 

contractor or operator. Compliance with project plan requirements and the operating plan is 

ensured by the COR, or ER through inspection.

6. Dispersion of Subsurface Drainage from Cut and Fill slopes 

(Practice: 2-6)

a. Objective: To minimize the possibilities of cut or fill slope failure and the subsequent production 

of sediment.

b. Explanation: This is a preventive practice. Roadways may change the sub-surface drainage 

characteristics of a slope. Since the angle and height of cut and fill slopes can increase the risk of 

instability, it is often necessary to provide subsurface drainage to avoid moisture saturation and 

subsequent slope failure. Where ground water dispersion is necessary because of slopes, soil, 

aspect, precipitation amounts, inherent instability, or other related characteristics, dispersion 

methods would include:

1) Underdrains or subdrains (e.g. pipes, geotextiles)

2) Horizontal drains or chimney drains

Dispersal of collected water will be accomplished in an area capable of withstanding 

increased flows. On erosive soils, energy dissipaters or other slope stabilization treatments or 

conveyance devices need to be placed below pipes carrying large volumes of water. Road 

surface may be designed to dissipate the intercepted water in a uniform manner along the 

road.

c. Implementation: Project location and detailed mitigation will be determined by design 

engineers and the IDT, documented and incorporated into subsequent project plans and 

contracts.

Project crew leaders and supervisors will be responsible for implementing force account 

projects to construction specifications as specified in the environmental analysis. Contracted 

projects are implemented by the contractor or timber sale operator. Compliance with project 

plan requirements and operating plans is ensured by the COR, FSR, or ER.

7. Control of Road Drainage (Practice: 2-7)

a. Objective: Is to minimize the erosive effects of water concentrated by road drainage features; to 

disperse runoff from disturbances within the road clearing limits; to lessen the sediment yield 

from roaded areas; to minimize erosion of the road prism by runoff from road surfaces and from 

uphill areas.

b. Explanation: This is a preventive practice. A number of treatments can be used, alone, or in 

combination, to control unacceptable effects of road drainage. Methods used to reduce erosion 

include but are not limited to such controls as construction of properly spaced cross drains, water 

bars or rolling dips; installing energy dissipaters, apron, downspouts, gabions, flumes, overside 

drains and debris racks; armoring of ditches, drain inlets and outlets and removing or adding 

berms to control runoff. Accomplish dispersal of runoff on the road surface by such means as 

rolling the grade, outsloping or crowning. Installing water spreading ditches or contour trenching 

can disperse road water after the water leaves the road surface.

Dispersal of runoff reduces downstream peak flows and associated scouring of the channels and 

sediment transport.

Reduce sediment loads from road surfaces by adding aggregate or paving surfaces or by 

installing such controls as: sediment filters, settling ponds, and contour trenches. Soil 

stabilization can reduce sedimentation by lessening erosion on borrow and waste areas, on cut 

and fill slopes, and on road shoulders.

c. Implementation: Project location, design criteria and detailed mitigation are determined and 

documented during the environmental analysis process. These are then incorporated into the 

project plan.

Project crew leaders and supervisors will be responsible for ensuring that force account projects 

meet construction specifications, and project criteria. Contracted projects are implemented by 

the contractor, or operator. Compliance with plans, specifications, and operating plans is 

ensured by the COR, ER, or FSR.

This practice is required in contracts when the need is identified in the project planning process.

8. Constraints Related to Pioneer Road Construction (Practice: 2-8)

a. Objective: To minimize sediment production and mass wasting from pioneer road construction.

b. Explanation: Pioneer roads are built to allow equipment access for construction of planned 

roadways. Pioneering is usually done within the roadway construction corridor of the planned 

road. To meet the objective of minimizing sediment the following constraints will be followed:

1)Confine construction of pioneer roads to the planned roadway construction limits unless 

otherwise specified or approved by the ER or COR.

2)Locate and construct pioneering roads to prevent undercutting of the designated final cut 

slope, avoid deposition of materials outside the designated roadway limits, and accommodate 

drainage with temporary culverts or log crossings.

3)Complete erosion control work prior to the rainy season and in accordance with contract, or 

project plan requirements.

4) Dewater sites on live streams crossed by pioneer roads with diversion devices (see Practice 2-

15).

c. Implementation: Determine and document project location and describe mitigations set forth 

during the environmental analysis process. Incorporate them into subsequent project plans 

and/or contracts.

Project crew leaders and supervisors will be responsible for implementing force account 

projects according to construction specifications and as specified in the project plan.

Contracted projects are implemented by the contractor, or timber sale operator. Compliance with 

plans, specifications, and operating plans is ensured by the COR, FSR, or ER.

9. Timely Erosion Control Measures on Incomplete Roads and 

Stream Crossing Projects (Practice: 2-9)

a. Objective: To minimize erosion and sedimentation from disturbed ground on incomplete 

projects.

b. Explanation: The best drainage design can be ineffective if erosion control has not been 

completed by the end of the normal operating season. Affected areas can include roads, road 

fills, tractor trails, skid trails, landings, stream crossings, bridge excavations, and fire lines. 

Preventive measures include:

1)Removal of temporary culverts, culvert plugs, diversion dams, or elevated stream crossings.

2)Installation of temporary culverts, side drains, flumes, cross drains, diversion ditches, energy 

dissipaters, dips, sediment basins, berms, debris racks, or other facilities needed to control 

erosion.

3)Removal of debris, obstructions and spoil material from channels and floodplains.

4) Planting vegetation, mulching, and/or covering exposed surfaces with jute mats or other 

protective material.

c. Implementation: Apply protective measures to all areas of disturbed, erosion-prone, 

unprotected ground that is not to be further disturbed in the present year. When conditions 

permit operations outside of the normal operating season, update the operating plan as necessary 

and keep erosion control measures sufficiently current with ground disturbance to allow rapid 

closure when weather conditions deteriorate. Do not leave project areas for the winter with 

remedial measures incomplete.

Develop project mitigation measures and layout requirements during the environmental analysis 

process. Incorporate them into subsequent project plans and/or contracts.

Project crew leaders and supervisors are responsible for ensuring that force account projects 

meet construction specifications and project criteria.

Contracted projects are implemented by the contractor or operator. Compliance with project 

plan criteria, contract specifications and operating plans is ensured by the COR, ER, or FSR.

10. Construction of Stable Embankments (Fills) (Practice: 2-10)

a. Objective: To construct embankments with materials and methods, which minimize the 

possibility of failure and subsequent water quality degradation.

b. Explanation. The failure of road embankments and the subsequent deposition of material into 

waterways may result from the incorporation of slash, or other organic matter into fills, from a 

lack of compaction during the construction of the embankment, or use of inappropriate 

placement methods.

To minimize fill failures, design and construct the roadway as a stable and durable earthwork 

structure with adequate strength to support the treadway, shoulders, subgrade and the roads 

traffic loads. Proper slope ratio design will promote stable embankments. Adjacent to SMZs 

construct and place embankments of inorganic material by methods 2 to 6 below. Construct or 

place other embankments of inorganic material by one, or more of the following methods:

1) Sidecasting and end dumping

2)Layer placement

3)Layer placement (roller compaction)

4)Controlled compaction

5) Special project controlled compaction

6)In some situations it will be necessary to minimize fill volumes and/or strengthen fills using 

retaining walls, confinement systems, plantings or a combination of techniques.

On projects, where required densities are specified, some type of moisture compaction 

control will be necessary. Where outer faces of embankments are not stabilized, due to 

equipment access difficulty, unfinished slopes subject to erosion and slipping will be 

stabilized following Practice 2-4.

c. Implementation: Project requirements and mitigation measures are developed and documented 

during the environmental analysis and road design process, by the IDT. The appropriate method 

of embankment placement is chosen during this process.

Project crew leaders and supervisors will be responsible for implementing force account 

projects, to construction specifications and project criteria. Contracted projects are implemented 

by the contractor, or operator. Compliance with project plan specifications, and the operating 

plan is ensured by the COR, CI and ER through inspection.

11. Control of Sidecast Material during Construction and Maintenance

(Practice: 2-11)

a. Objective: To minimize sediment production originating from sidecast material during road 

construction or maintenance.

b. Explanation: Unconsolidated materials including rocks and boulders that are cast over the side 

of the road shoulder can roll directly into streams, damage downslope vegetation and create bare 

areas that are difficult to stabilize with vegetation. Where spoil does not directly reach a stream, 

it is still highly susceptible to erosion, dry ravel and mass instability, and subsequently can 

directly deliver sediment to a nearby stream. Site-specific limits and controls for side casting or 

end hauling are developed and documented during environmental analysis. Loose, 

unconsolidated sidecast material must not be permitted to enter SMZs, (see Practice 2-17).

Sidecasting is an unacceptable construction alternative in areas where it can adversely impact 

water quality. Prior to the start of construction, or maintenance activities, waste areas must be 

located where excess material can be deposited and stabilized. During road maintenance 

operations, potential sidecast and other waste material will be utilized on the road surface or 

removed to designated disposal sites.

The roadway will be constructed within reasonable limits of the lines, grades, and dimensions 

given in the engineering drawings and designated on the ground. Provisions for waste material 

disposal are included in every road construction and maintenance contract.

c. Implementation: Project location, selected disposal areas, and mitigation will be developed and 

documented during the environmental analysis.

Project crew leaders and supervisors will be responsible for ensuring that force account projects 

meet construction specifications and project criteria. Road maintenance plans are developed for 

each forest and include slide and slump repairs and disposal site locations for excess material.

Contracted projects are implemented by the contractor or timber sale operator. Compliance with 

project criteria, contract specifications, and operating plans will be enforced by the COR, ER, or 

FSR. Standard maintenance specifications have been prepared which include disposal area 

operation, disposal methods, and surface treatment.

Timber sale contracts include clause C5.4 to address temporary road maintenance 

specifications, which includes slide and slump repair, surface blading, and side casting during 

road maintenance.

12.Servicing and Refueling of Equipment (Practice: 2-12) 

a. Objective: To prevent pollutants such as fuels, lubricants, bitumens and other harmful materials 

from being discharged into or near rivers, streams and impoundments, or into natural or manmade channels.

b. Explanation: During servicing and refueling of logging and road construction equipment, any 

spilled pollutants can be transported by runoff to surface waters. If the volume of fuel exceeds 

660 gallons in a single container, or if total storage at a site exceeds 1,320 gallons, project Spill 

Prevention, Containment and Counter Measures (SPCC) plans are required. Contaminated 

upland soils can be a long-term threat to surface and ground water quality. This threat must be 

managed by disposing of waste material properly, selecting service and refueling areas well 

away from wet areas and surface water; by using berms around such sites and by utilizing 

impermeable liners or other techniques to contain spills according to the Forest SPCC plan.

c. Implementation: The COR, ER, CI, or TSA are authorized to designate the location, size and 

allowable uses of service and refueling areas. Operators are required to remove service residues, 

waste oil and other materials from National Forest land. They must also be prepared to take 

responsive actions in case of a hazardous substance spill, according to the Forest SPCC plan.

13. Control of Construction and Maintenance Activities Adjacent to 

SMZs (Practice: 2-13)

a. Objective: To protect water quality by controlling construction and maintenance actions within 

and adjacent to any streamside management zone so that the following SMZ functions are not 

impaired:

1) Acting as an effective filter for sediment generated by erosion from bare surfaces, road fills, 

dust drift, and oil traces;

2)Maintaining shade, riparian habitat (aquatic and terrestrial), and channel stabilizing effects;

3) Keeping the floodplain surface in a resistant, undisturbed condition to slow water velocities 

and limit erosion by flood flows.

b. Explanation: Construction and maintenance fills, sidecast, and end-hauled materials are kept 

out of SMZs except at designated sites to minimize effects on the aquatic environment. Factors 

such as stream class, channel stability, sideslope steepness, ground cover, and sideslope stability 

are taken into account in developing zone widths. In some situations, SMZ widths are 

established by records of decision and by EIS standards and guidelines (e.g. PACFISH EA, 

Northwest Forest Plan ROD). It is also necessary to stabilize fill slopes to prevent sediment 

accumulations in the streamside zone.

SMZs are determined and documented during the environmental analysis process by the IDT, 

which includes hydrologists, fishery biologists, and other specialists as required.

c. Implementation: Project location alternatives are formulated, and mitigation measures 

developed by the IDT are included into the contract by design engineers. Project crew leaders 

and supervisors are responsible for ensuring that force account projects meet maintenance and 

construction specifications and project criteria.

Contracted projects are implemented by the contractor, or operator. Compliance with mitigation 

measures, contract specifications, and operating plans is ensured by the COR, FSR, or ER.

14. Controlling In-Channel Excavation (Practice: 2-14)

a. Objective: To minimize stream channel disturbances and related sediment production.

b. Explanation: During construction, heavy equipment may need to cross, or work in and near 

streams or lakes. This is permitted only as necessary in the construction, or removal of culverts 

and bridges and other facilities (e.g. water sources, boat ramp/launching sites, etc.) and only 

under specific protection requirements. The Engineering Representative (ER) is authorized to 

designate the location of crossings or work sites and coordinate with the contractor to manage 

heavy equipment.

Excavation during the installation of instream structures must follow all of the following 

minimum water quality protection requirements.

1) Unless otherwise approved, no excavation will be made outside of caissons, cribs, cofferdams, 

or sheet piling.

2)The natural streambed or lake bottom adjacent to the structure will not be disturbed without 

prior approval of the ER or COR.

3)If any excavation, or dredging is made at the site of the structure before caissons, cribs, or 

cofferdams are sunk in place, all such excavations will be restored to the original surface and 

the streambed or lake bottom must be protected with suitable stable material.

4)Material deposited within the stream or lake area from foundation, or other excavation will not 

be discharged directly into live streams or lakes, but will be put into settling areas as shown 

on the engineering drawings or as approved by the ER, or COR. (See Practice 2-15)

5)If the channel or lake bottom is disturbed during construction, it must be restored to its 

original configuration while minimizing any additional disturbance.

6) Disturbances of stream or lake banks are kept to a minimum. Disturbed banks are stabilized.

c. Implementation. Mitigation measures developed by the IDT are set forth in the environmental 

documentation and incorporated into the contract by design engineers. Project crew leaders and 

supervisors will be responsible for ensuring that force account projects meet construction 

specifications and project criteria.

Contracted projects are implemented by the contractor or operator. Compliance with mitigation 

measures, contract specifications, and operating plans is enforced by the CI, COR, FSR or ER.

15. Diversion of Flows around Construction Sites (Practice: 2-15)

a. Objective: To ensure that all stream diversions are carefully planned, to minimize downstream 

sedimentation, and to restore stream channels to their natural grade, condition, and alignment as 

soon as possible.

b. Explanation: Streamflow must be diverted around construction sites such as bridges, culverts 

and dams. The streamflow will be diverted for all live streams according to the instructions of 

the ER. The diverted flows are returned to their natural streamcourse as soon as possible after 

construction or at least prior to the rainy season. All disturbed areas are stabilized prior to the 

rainy season or as needed.

c. Implementation: This practice is required by contract clauses. The NEPA and design process 

will identify where diversions are required, and the design will include mitigation necessary to 

protect instream values and downstream beneficial uses of the water. Planning must include 

environmental analysis to identify and prevent unacceptable effects to the beneficial uses of the 

water. The planning process may require project review and/or issuance of permits or 

certifications by other Federal, State, or local agencies and, where appropriate, private parties.

Case by case determinations must be made during project planning as to out-service review and 

consultation needs. Coordination with California Department of Fish and Game (CDFG) is 

initiated in most all cases.

Project location, bypass design, and detailed mitigation will be developed in the design and 

planning process to meet project criteria. Project crew leaders and supervisors will be 

responsible for implementing force account projects to construction specifications and to meet 

project criteria.

Contracted projects are implemented by the contractor, or operator. Compliance with project 

criteria, contract specifications and operating plans is enforced by the CI, COR, ER, or SA.

16.Stream Crossings on Temporary Roads (Practice: 2-16)

a. Objective: To ensure that temporary roads do not unduly damage stream channels and to ensure 

that fish passage is unimpeded by stream crossing structures.

b. Explanation: Stream crossing structures (e.g. culverts, bridges) are required on all temporary 

roads where it is necessary to cross designated channels. Means of crossing will include but not 

be limited to, culverts, bridges, coarse rock fills, hardened fords, (using such features as rocked 

approaches), and low water crossings. Identifying locations to cross streams will be 

accomplished using an IDT. Such crossings are designed to provide for unobstructed flows and 

the passage of fish, and to minimize damages to stream channels and water quality.

The number of crossings is kept to the minimum needed for access. Channel crossings will be as 

perpendicular to stream courses as possible. Streambank excavation will be kept to the minimum 

needed for use of the crossings, and entry and exit ramps may need to be rocked. Fords and 

turnpike crossings hardened with washed rock, concrete planks, slabs or geogrid are sometimes 

an acceptable alternative, depending on water quality, fishery and hydrological considerations.

Temporary crossing facilities will be removed and the site stabilized prior to the rainy season 

each year or when the facility is no longer needed, which ever is earliest.

c. Implementation: This practice is required when documented in the project plan. In timber 

sales, stream crossing are located, and mitigation is implemented by the SA, using instructions 

in the TSA Handbook, supplemental Forest guidelines, and considering IDT recommendations.

Mitigation at sensitive stream crossings must be assessed, and controls prescribed during the 

environmental analysis by the IDT.

Project crew leaders and supervisors will be responsible for ensuring that force account projects 

meet construction specifications and project criteria.

Contracted projects are implemented by the contractor, or operator. Compliance with the 

requirements in the project plan, contract and/or operating plan is ensured by the CI, COR, FSR, 

SA, or ER.

17. Bridge and Culvert Installation (Practice: 2-17)

a. Objective: To minimize sedimentation and turbidity resulting from excavation for in-channel 

structures.

b. Explanation: Excavation is a common requirement for the installation of bridges, culverts, 

weirs, check dam, riprapping and other structures. Spoil material generated during construction 

should neither obstruct the stream course (including natural floodplains) nor impair the 

efficiency of the associated structures. Preventive measures include:

1) Keep excavated materials out of channels.

2)Remove any materials stacked, or stockpiled on floodplains prior to the rainy season.

3) Divert flowing water around work sites to minimize erosion and sedimentation.

4) Suitably locate bypass roads and develop plans for their subsequent obliteration and 

stabilization.

5)In some cases, fill material may have to be imported for better soil compaction. Original fill 

may have to be exported to a disposal site.

Streams identified as important for fisheries or other aquatic resources may require that the 

channel not be disturbed except during flow periods specified in the project plan. Normally, this 

work would occur during low flow periods. Work would not be allowed during spawning 

periods, or other periods critical to aquatic resources. Downstream sediment basins or other 

sediment reduction facilities or techniques will be necessary to mitigate impacts.

c. Implementation: Project location and detailed mitigation measures will be developed during 

the design process to meet project criteria, using an interdisciplinary process.

Project crew leaders and supervisors will be responsible for ensuring that force account projects 

meet construction specifications and project criteria.

18. Regulation of Streamside Gravel Borrow Areas (Practice: 2-18)

a. Objective: To limit channel disturbances and sediment production associated with gravel source 

development.

b. Explanation: Materials deposited along channels by storm runoff often provide a source of 

gravel. With adequate planning gravel can be removed with minimal impact on water resources 

and channel stability. Gravel removal can alter streamflow characteristics and consequently 

effect channel stability and create a new sediment source. Borrowing will be limited to material 

deposited above the bankfull line. Borrow area shaping or other special drainage reconfiguration actions are taken to maintain channel function.

Excavation will not take place below the water table unless sediment basins are built to contain, 

or catch the resulting sediment. Sediment basins should not be subject to washouts. If excess 

sediment accumulates in basins, the basin will be cleaned and the sediment deposited and 

stabilized at approved sites outside the area where it could re-enter the stream.

Wash water or waste from concrete batching, or aggregate operations will not be allowed to 

enter streams prior to treatment by filtration, flocculation, settling, and/or other means. (See also 

Practice 3-3)

c. Implementation: Project location, stability and the limits for disturbance and sediment 

production will be developed through the environmental analysis and the IDT and in 

consultation with State Fish and Game or other pertinent agency. Detailed mitigation measures 

will be developed by the design engineer to meet project criteria.

Project crew leaders and supervisors will be responsible for implementing force account 

projects to construction specifications and project criteria.

Contracted projects are implemented by the contractor or operator. Compliance with project 

criteria, contract specifications, and operating plans is ensured by the CI, FSR, COR, or ER.

Special us permits issued for gravel bar excavation will include the above requirements, an 

operating plan and reclamation plan if warranted. District Rangers or their representatives will 

be responsible for ensuring compliance.

19. Disposal of Right-of-Way and Roadside Debris (Practice: 2-19)

a. Objective:

1)To ensure that organic debris generated during road construction is kept out of streams so that 

channels and downstream facilities are not obstructed.

2)To ensure debris dams are not formed which obstruct fish passage, or which could result in 

downstream damage from high water flow surges after dam failure.

b. Explanation: As a preventive measure, construction debris and other newly generated roadside 

slash developed along roads in the streamside management zone is disposed of by the following 

means as applicable: (See also Practice 2-11)

1) On Site:

a) Piling and burning

b) Burying

c) Chipping

d) Scattering

e) Disposal in cutting units

f) Windrowing at the base of fill slopes

g) Incorporation {only in temporary roads}

2)Removal to agreed upon locations (especially stumps from the road prism).

3) A combination of the above.

4)Large limbs and cull logs are removed to designated sites outside the SMZ or relocated within 

the zone to meet aquatic resource management objectives.

c. Implementation: Criteria for the disposal of right-of-way and roadside debris will be 

established during onsite evaluation by an IDT. Project location and detailed mitigation 

measures are also developed and set forth in the environmental analysis and incorporated into 

project plans and/or contracts.

Project crew leaders and supervisors will be responsible for ensuring that force account projects 

meet construction specifications.

Contracted projects are implemented by the contractor or operator. Compliance with plans, 

specifications, and operating plans is ensured by the CI, COR, or ER.

20.Specifying Riprap Composition (Practice: 2-20)

a. Objective: To minimize sediment production associated with the installation and utilization of 

riprap material.

b. Explanation: Riprap is commonly used to armor streambanks and drainage ways from the 

erosive forces of flowing water. Riprap must be sized and installed in such a way that it 

effectively resists erosive water velocities. On occasion, this may require the use of filter 

blankets, or other methods to prevent undermining. Stone used for riprap will be free of weakly 

structured rock, soil, organic material and other material not resistant to streamflow that would 

only serve as sediment sources. Outlets of drainage facilities on erodible soils commonly require 

riprapping for energy dissipation. The Corps of Engineers and Federal Highway Administration 

procedures are commonly used for designing riprap structures.

c. Implementation: Project location and detailed mitigation will be developed through the 

planning and design process to meet the mitigation measures and requirements of the project 

plan.

Project crew leaders and supervisors will be responsible for implementing force account projects 

to construction specifications and project criteria.

Contracted projects are implemented by the contractor or operator. Compliance with project 

criteria and operating plans is ensured by the COR, or ER.

Reasonably Foreseeable 

Projects and 

Cumulative Effects 

Motorized Travel Management Supplemental Draft Environmental Impact Statement – February 2010

Tahoe National Forest – H-1

Appendix H: Reasonably Foreseeable Projects

and Cumulative Effects

According to the Council on Environmental Quality (CEQ) NEPA regulations, “cumulative impact” is the 

impact on the environment which results from the incremental impact of the action when added to other 

past, present, and reasonably foreseeable future actions regardless of what agency (Federal or nonFederal) or person undertakes such actions (40 CFR 1508.7).

The cumulative effects analysis area is described under each resource, but in most cases includes the 

entire TNF including private and other public lands that lie within the Forest boundary. Past activities are 

considered part of the existing condition and are discussed in the “Affected Environment (Existing 

Conditions)” and “Environmental Consequences” section under each resource. 

In order to understand the contribution of past actions to the cumulative effects of the proposed action 

and alternatives, this analysis relies on current environmental conditions as a proxy for the impacts of past 

actions. This is because existing conditions reflect the aggregate impact of all prior human actions and 

natural events that have affected the environment and might contribute to cumulative effects.

This cumulative effects analysis does not attempt to quantify the effects of past human actions by adding 

up all prior actions on an action-by-action basis. There are several reasons for not taking this approach.

First, a catalog and analysis of all past actions would be impractical to compile and unduly costly to 

obtain. Current conditions have been impacted by innumerable actions over the last century (and beyond), 

and trying to isolate the individual actions that continue to have residual impacts would be nearly 

impossible. Second, providing the details of past actions on an individual basis would not be useful to 

predict the cumulative effects of the proposed action or alternatives. In fact, focusing on individual 

actions would be less accurate than looking at existing conditions, because there is limited information on 

the environmental impacts of individual past actions, and one can not reasonably identify each and every 

action over the last century that has contributed to current conditions. Additionally, focusing on the 

impacts of past human action risks ignore the important residual effects of past natural events, which may 

contribute to cumulative effects just as much as human action. By looking at current conditions, we are 

sure to capture all the residual effects of past human actions and natural events, regardless of which 

particular action or event contributed those effects. Third, public scoping for this project did not identify 

any public interest or need for detailed information on individual past actions. Finally, the Council on 

Environmental Quality issued an interpretive memorandum on June 24, 2005 regarding analysis of past 

actions, which states, “agencies can conduct an adequate cumulative effects analysis by focusing on the 

current aggregate effects of past actions without delving into the historical details of individual past 

actions.” Past actions are treated similarly in the recently published Forest Service Regulations for 

implementing the National Environmental Policy Act (36 CFR 220). For these reasons, the analysis of 

past actions in this section is based on current environmental conditions

In addition to considering the effects of this proposal on other lands, this EIS considers the likely 

effects on lands administered by the Forest Service from past, ongoing, and reasonably foreseeable 

management actions occurring on other forest lands. Management of other lands could directly affect

terrestrial and aquatic wildlife species that move between ownerships during the year or during their life 

cycle. The possible contribution of management actions on other lands has been considered in analyzing 

the effects of the alternatives on species and habitats that are not confined to national forests..

Reasonably Foreseeable Projects__________________________

Table H-1 lists present and reasonably foreseeable future actions potentially contributing to cumulative 

effects. While the table lists all actions, every resource is not affected by every action. For example, a 

future project may affect wildlife but not affect water quality. Table H-1 indicates which resources are 

potentially affected by each action.

Appendix I: Riparian Conservation Objectives

Background Information _____________________________________

The Sierra Nevada Forest Plan Amendment (SNFPA), Final Supplemental Environmental Impact 

Statement Record of Decision (USDA Forest Service 2004a) describes management goals and strategies 

for aquatic, riparian, and meadow ecosystems.

The following elements are part of the goals of the Aquatic Management Strategy of the SNFPA:

• Water quality

• Species viability

• Plant and animal community diversity

• Special habitats

• Watershed connectivity

• Floodplains and water tables

• Watershed condition

• Stream banks and shorelines

The aquatic, riparian, and meadow ecosystem strategy has the following key elements:

• A description of desired conditions for aquatic, riparian, and meadow habitats developed from the 

AMS goals;

• A set of land allocations, specifically riparian conservation areas and critical aquatic refuges, that 

delineate aquatic, riparian and meadow habitats, which are to be managed consistent with the 

Riparian Conservation Objectives (RCOs) and associated Standards and Guidelines;

• An adaptive management program that includes monitoring and research activities specifically 

aimed at assessing effects of management activities on the willow flycatcher and Yosemite toad; 

and

• The use of landscape analysis as a tool for assessing existing uses and identifying restoration and 

enhancement projects.

In order to achieve the element described above, the SNFPA Record of Decision (ROD) requires that 

a site-specific analysis be conducted in order to determine the type and extent of activities that can occur 

within Riparian Conservation Areas (RCAs) adjacent to aquatic features. Specifically, the ROD contains 

Riparian Conservation Objectives with associated Standards and Guidelines that must be met for 

activities within RCAs. This analysis examines how the Tahoe National Forest (TNF) Motorized Travel 

Management EIS meets the Standards and Guidelines for each Riparian Conservation Objective.

Determinations Specific to this RCO Analysis

It is important to note that this project does not propose any new road or trail construction. The routes 

being analyzed currently exist on the ground and have been used by motorized, wheeled vehicles in the 

recent past. All of the action alternatives propose to reduce the miles of native surface, motorized routes

across the watersheds and in RCA and the number of stream crossings and would therefore decrease the 

impacts to Riparian Conservation Areas on the Tahoe National Forest.

Riparian Conservation Objective Standards and Guidelines ________

The RCOs provide a checklist for evaluating whether a proposed activity is consistent with the desired 

conditions described in the Aquatic Management Strategy. Each Standard and Guidelines and how they 

are met by the TNF Motorized Travel Management project are described below.

Standard and Guideline # 91

Designate riparian conservation area (RCA) widths as described in Part B of this appendix. The RCA 

widths displayed in Part B may be adjusted at the project level if a landscape analysis has been 

completed and a site-specific RCO analysis demonstrates a need for different widths.

Consistency Determination: This project designated riparian conservation area (RCA) widths as 

described in Part B of Appendix A in the 2004 Sierra Nevada Framework. No adjustments were made to 

those widths. Table I-1 displays the widths used in designating the widths for RCAs in this project. 

Table I-1. Riparian Conservation Areas (RCAs) as designated by the Sierra Nevada Forest Plan Amendment 

Record of Decision (SNFPROD) of 2004

Aquatic feature Riparian Conservation Area

Perennial stream. 300 feet on each side of the stream, measured from the 

bank full edge of the stream

Seasonally flowing streams 150 feet on each side of the stream, measured from the 

bank full edge of the stream

Special aquatic features (includes lakes, wet meadows, 

bogs, fens, wetlands, vernal pools, and springs).

300 feet from the edge of the features or riparian 

vegetation, whichever width is greater.

Perennial streams with riparian conditions extending 

more than 150 feet from the edge of the streambank or 

seasonally flow streams extending more than 50 feet 

from the edge of the streambank.

300 feet from the edge of the features or riparian 

vegetation, whichever width is greater.

Streams in inner gorge. Top of inner gorge. (The inner gorge is defined by stream 

adjacent slopes greater than 70 percent gradient.)

Standard and Guideline #92

Evaluate new proposed management activities within CARs and RCAs during environmental analysis to 

determine consistency with the riparian conservation objectives at the project level and the AMS goals for 

the landscape. Ensure that appropriate mitigation measures are enacted to (1) minimize the risk of 

activity-related sediment entering aquatic systems and (2) minimize impacts to habitat for aquatic- or 

riparian-dependent plant and animal species.

Consistency Determination: The following management activities within CARs and RCAs were 

evaluated to determine their consistency with the riparian conservation objectives as part of this project;

It is important to note that while adding existing unauthorized routes to the transportation system is 

considered a new management activity, it does not result in new ground disturbance or the physical

construction of new roads. Guidance for this determination was provided by the Regional Office of the 

Forest Service (USFS, Region 5) in February 2008.

1. Prohibition on cross country travel will be a new management activity and will decrease the 

amount of use.

2. Additions of unauthorized routes to the NFTS as roads or trails will be subjected to new 

management activities.

3. Addition of the proposed designated motorized open areas will result in new management 

activities.

4. Changes to the NFTS

a. Existing ML-2 roads (maintenance level 2 roads) that will remain as ML-2 roads under the 

action alternatives were not included in the RCO analysis. This is because existing ML-2 

roads that remain as ML-2 roads will not be subjected to new management activities or a new 

type of use (i.e. the management and type of use will not change as a result of the action 

alternatives). 

b. Routes proposed for mixed use will not result in new management activities, these are preexisting routes. The only change is the class of vehicle, there is no change in footprint of 

route.

c. Change in maintenance level will result in these routes being in the higher risk route category, 

but all routes will meet resource objectives.

d. The proposed change in season of use will result in new management activities and will 

decrease the use of routes in RCAs during the wet season.

e. Existing ML-1 roads (maintenance level 1 roads) that will be re-opened and upgraded to a 

higher maintenance level (ML-2, ML-3, etc.) under the action alternatives were included in 

the RCO analysis. This is because existing ML-1 roads that are re-opened and upgraded to a 

higher maintenance level will be subjected to new management activities and possibly a 

greater amount of use. 

f. The proposed forest plan amendment is covered under change in season of use.

The results of this evaluation are described in this Appendix below for each of the individual riparian 

conservation objectives. Additional information is also presented in Chapters 3.02 (Watershed Resources: 

Geology, Soil, Hydrology), 3.03 (Terrestrial & Aquatic Species), 3.06 (Plant Communities), Appendix F 

(Watershed Analysis), and Appendix A (Site Specific Road, Trail and Open Area Information).

Appropriate mitigation measures were enacted to (1) minimize the risk of activity-related sediment 

entering aquatic systems and (2) minimize impacts to habitat for aquatic- or riparian-dependent plant and 

animal species. These mitigation measures are specified in Appendix A and in Chapter 2 (The 

Alternatives) of this EIS. Table I-2 displays these mitigation measures.

vegetation.

SV-P14 Additional drainage structures or culvert installed along 40' segment where ephemeral 

stream follows route. Place water bars to prevent water from using route as drain channel.

Place boulders or other barriers on both sides of the route where it passes through the 

aspen clone to reduce impacts to the aspen.

SV-P14a Additional water bar should be installed near west end of route. Install water bar at eastern end.

SV-P5 At first crossing need to divert intermittent channel off route. The second crossing is a 

perennial crossing. The sediment at the perennial crossing is primarily tire wash and 

redistribution of fines within the channel. This crossing could use some additional gravel on 

both approaches to reduce the channel widening and sedimentation into this tributary to 

Haypress Creek.

SV-P8 Repair existing waterbar. Additional waterbars installed near end of route to divert runoff 

from the route before sediment reaches the Little Truckee River.

TKN-J10 Waterbars installed to divert stream channel from route.

TKN-J11 Place barriers to keep motorized use off the Ivesia sericoleuca in Hoke Valley and to keep 

vehicles out of the meadow.

TKN-J13 ((Alts 2, 4, 

5, 7)

Multiple routes traverse the area. 6”-12” ruts are present. Trail is in 303d watershed. Rock 

the sections of route where rutting and wet soils are present..

TKN-J2 Place barriers around the vernal pool/seasonal wetland so that damage from motorized use 

is reduced/eliminated.

TKN-J4 Drainage control structures need to be installed to mitigate impacts.

TKN-J5 Mitigate seep at beginning of route. Need to outslope eastern end. In steeper areas, 

additional waterbars should be installed to divert runoff from the route. Redirect water flow 

from the seep/spring at the beginning of the route and from overland flow down a portion of 

the route to Castle Creek – to the meadow. Place barriers and signs in the areas adjacent to 

Castle Creek to keep users from reducing vegetative cover adjacent to Castle Creek. Place 

barriers so that turn arounds, dispersed recreation, and parking do not occur within 100 feet 

of Castle Creek to reduce impacts to the Bruchia bolanderi occurrence. Ensure that the 

crossing of Castle Creek is not widened during high flows to reduce impacts to the rare 

moss – Bruchia bolanderi - field check the route annually.

TKN-J9 (Alt 2, 5, 6 

and 7)

Waterbars should be installed at all three crossings to mitigate erosion and sedimentation 

impacts.

TKN-M1 Additional water bar should be installed on 100' segment of 18% gradient to minimize 

widening of route.

Route ID Mitigation Measure

TKN-M2 Improve crossings at northern and southern routes. Place boulders on either side of the 

route where it passes through the Ivesia sericoleuca occurrence. Place boulders to block the 

access to the illegal spur that also goes through part of the Ivesia sericoleuca occurrence. 

Place boulders on either side of the route to make sure vehicles stay on the route where it 

passes through the aspen.

TKN-Q1 Drainage structures needed along northern 50-foot segment of route.

TKS-11 Drainage structures need to be installed. Remove outhouse and fill pit. Construct drainage 

structures to reduce impacts to adjacent wetlands. Place barriers at the edges of the route 

where the route passes through the aspen clone/wet meadow complex to reduce impacts to 

those resources.

YRM-M3 Water bars need to be placed to control rill erosion and to restore proper drainage function.

YRN-001 Place barriers at the end of the route to prevent/reduce impacts to the Epilobum howellii.

YRN-004 Waterbars installed to mitigate the erosion impacts.

YRN-007 Install waterbars to control erosion at the stream crossing.

YRN-008 Block end of route to prevent Brandy City Diggins from being used an open area for hill 

climbs. Place barriers along the route to keep vehicles from driving up the sides of the 

diggings.

YRN-11 Place barriers at end of route to prevent encroachment into meadow.

YRN-2 Placement of properly-spaced waterbars is required to mitigate these impacts. The northernmost crossing will need drainage structures on the right bank to minimize impacts.

YRN-7 Additional water bars would be installed near the top of the route to control runoff. Place 

barriers to define route through the occurrence of the watchlist plant Erigeron petrophilus

var. sierrrensis.

YRN-M2 Mitigation measures in the form of drainage structures, crossing protection, and debris slide 

treatments, are necessary.

YRN-M3B Mitigation measures in the form of drainage structures, crossing protection, and debris slide 

treatments, are necessary.

YRS-003B Mitigation measures in the form of additional drainage structures.

YRS-066 Drainage structure needed near ephemeral stream crossing. Drainage control structures 

needed.

needed.

YRS-AF Mitigate impacts by pulling back motorized use 75 feet from the lake.

YRS-B5 Drainage structures.

YRS-F1 Old vehicle parts in creek need to be removed. Close spurs. Water bars needed at bottom of 

Section 4. Place barriers between the lakeshore and the route at the waterfall site to reduce 

impacts to riparian vetgetation from motorized vehicles.

YRS-G3, YRS-G3w Drainage structures needed.

Greenhorn Area Close adjacent hill climbs. Designate specific water crossings.

YRS-SF4 Drainage structures needed. Protect approaches to stream crossing by installing waterbars 

to control road drainage.

YRS-SF5 Minor re-routes needed to keep trail away from the creek and prevent erosion. Some 

waterbars needed. Repair gullies. Place barriers between the route and the spur going into 

the wetland. Restore the wetland by raking out the ruts and placing woody debris over the 

ruts. Place barriers between the route and the spur going down to the pond/wetland.

YRS-SF6 Section needs drainage control and waterbars.

YRS-SF6b Section needs drainage control and waterbars to mitigate these impacts. Fix the slump into 

the drainage to reduce impacts to riparian vegetation.

I-6 – Tahoe National Forest

Standard and Guideline #93

Identify existing uses and activities in CARs and RCAs during landscape analysis. At the time of permit 

reissuance, evaluate and consider actions needed for consistency with RCOs. 

Consistency Determination: This Standard and Guideline is not applicable since there are no permit 

reissuances associated with the project.

Standard and Guideline #94

As part of project-level analysis, conduct peer reviews for projects that propose ground-disturbing 

activities in more than 25 percent of the RCA or more than 15 percent of a CAR.

Consistency Determination: Table I-2 displays the number of roads and motorized trails within 100 

feet of riparian vegetation as well as the native surface road and motorized trail route miles and density 

within riparian conservation areas. No peer review is required for this project since none of the 

alternatives propose new ground-disturbing activities and that all of the action alternatives will reduce the 

amount of native-surface, motorized routes within RCAs and CARs by 20 to 31 percent. Alternatives 3, 4, 

and 5 will also prohibit cross country motorized travel within all RCAs. Alternative 2 designates “Open 

Areas” at Boca, Prosser, and Stampede Reservoirs to allow motorized access to the shorelines. Alternative 

2 will also designate Greenhorn as “Open Area” including lands within the RCA. Alternative 6 will 

designate 244 acres of shorelines at Boca, Prosser and Stampede Reservoirs as “Open Areas” to allow for 

access to the reservoirs to continue. These open areas are generally on flatter, rock hardened sites that 

have been heavily used for access in the past and are a low risk to RCA and watershed resources. 

Motorized use at these areas will be limited to highway legal vehicles only from May 1 to December 31.

Big Dawg Cove is the steepest site with the highest potential for impact to Boca Reservoir water quality.

With proper maintenance and management, detrimental impacts will be mitigated.

participated in and supported the development of Total Maximum Daily Loads (TMDLs) and TMDL 

Implementation Plans. Of those impaired water bodies listed in the Table, only the Truckee River has an 

implementation plan. The Forest Service briefed the Lahontan Regional Water Quality Control Board on 

the consistency of this project with the Implementation Plan on May 14, 2008. All of the action 

alternatives are fully consistent with the Implementation Plan since based on the following criteria as 

presented to the Water Board;

• All of the action alternatives reduce potential sediment production

• All of the action alternatives reduce the number of motorized native surface stream crossings

• All of the action alternatives reduce native surface road and motorized trails route density across 

the landscape and within Riparian Conservation Areas (RCAs)

• Many of the action alternatives close native-surface routes to motorized use during the wet season

• All of the action alternatives prohibit cross country travel

• Identify restoration needs are identified in the project record

RCO #1 Standard and Guideline #96

Ensure that management activities do not adversely affect water temperatures necessary for local 

aquatic- and riparian-dependent species assemblages.

Consistency Determination: Water temperatures necessary for local aquatic and riparian dependent 

species assemblages can be adversely affected by roads and motorized trails. The adverse effects are 

primarily a result of shade reduction and stream crossings. The following criteria are used for establishing 

consistency with this Standard and Guideline.

1. Cross country travel within 100 feet of riparian vegetation, 

2. Number of roads and motorized trails within100 feet of riparian vegetation, 

3. The density of native surface roads and motorized trails within RCAs and 
Motorized Travel Management Supplemental Draft Environmental Impact Statement – February 2010

I-8 – Tahoe National Forest

4. The number of stream crossings.

There is no new ground disturbing activities proposed in this project, all routes currently exist in the 

ground. All of the action alternatives reduce the amount of adverse effects associated with each of these 

criteria compared to the existing condition (Alternative 1). Therefore all of the action alternatives are 

consistent with this Standard and Guideline. Table I-4 summarizes the changes in these criteria by 

alternative. Additional information is presented in Chapters 3.02 (Watershed Resources: Geology, Soil, 

Hydrology), 3.03 (Terrestrial and Aquatic Species) and 3.06 (Plant Communities). 

None of the alternatives propose new ground-disturbing activities. All of the action alternatives will 

reduce the amount of native-surface, motorized routes within RCAs and CARs by 20 to 31 percent. 

Alternatives 3, 4, and 5 will also prohibit cross country motorized travel within all RCAs. Alternative 2 

will allow motorized access to the shorelines of Boca, Prosser and Stampede Reservoirs to continue.

Alternative 2 will also allow the motorized use at Greenhorn Creek area to continue. Alternative 6 will 

designate 244 acres of shorelines at Boca, Prosser and Stampede Reservoirs as open areas to allow for 

access to the reservoirs to continue. These open areas are generally on flatter, rock hardened sites that 

have been heavily used for access in the past and are a low risk to RCA and watershed resources. Big 

Dawg Cove is the steepest site with the highest potential for impact to Boca Reservoir water quality. With 

proper maintenance and management, detrimental impacts will be mitigated. The action alternatives will 

also reduce the existing motorized stream crossings (perennial and intermittent) by 21 to 35 percent.

RCO #1 - Standard and Guideline #99

Prohibit storage of fuels and other toxic materials within RCAs and CARs except at designated 

administrative sites and sites covered by a Special Use Authorization. Prohibit refueling within RCAs and 

CARs unless there are no other alternatives. Ensure that spill plans are reviewed and up-to-date.

Consistency Determination: There is no decision regarding storage of fuels or other toxic materials 

being made with this project.

RCO #2 - Standard and Guideline #100

Maintain and restore the hydrologic connectivity of streams, meadows, wetlands, and other special 

aquatic features by identifying roads and trails that intercept, divert, or disrupt natural surface and 

subsurface water flow paths. Implement corrective actions where necessary to restore connectivity.

Consistency Determination: Hydrologic connectivity refers to the ease of movement, or rates of 

exchange, with which water, energy, nutrients, and organisms pass from one area to another, unhindered 

in the absence of impediments, such as dams, diversions, roads and bridges, large habitat openings, and 

recreational developments. As ecosystems become fragmented and disconnected, the scale and rate at 

which essential processes, such as nutrient and energy cycling and gene flow, operate become restricted.

The following are the criteria used for determining consistency.

1. Native surface road and motorized trail density in RCAs

2. Stream crossing density in RCAs

3. Number of wet meadows being impacted

4. Mitigation Measures required for adding motorized trails to the NFTS

5. Identification and prioritization of corrective actions

Densities of native surface and trails within Riparian Conservation Areas (RCAs) serve as a relative 

measure of watershed connectivity. The greater the density of native surface roads and trails open to 

motorized vehicles within RCAs, the greater the potential risk to watershed connectivity. All of the action 

alternatives reduce the densities of native surface and trails within RCAs by 20 to 31 percent and 

therefore maintains and restores hydrologic connectivity.

Another common measure of hydrologically connected routes is stream crossing densities. Many 

road-stream crossings have the potential to divert stream flow if drainage structures plug or fail. The 

number of crossings with diversion potential on the Tahoe National Forest is not known, so for the 

purpose of this analysis, all crossings are assumed to have diversion potential. The likelihood of 

diversions is therefore related to the numbers and densities of stream crossings. All of the action 

alternatives maintain and restore hydrologic connectivity by reducing the native surface, motorized 

route/stream crossing density in RCAs by 21 to 35 percent.

The condition of wet meadows is one of the components of the Riparian Conservation Objectives. 

Motorized roads and trails can adversely impact wet meadows. There are currently 231 wet meadows

intersected motorized roads and trails on National Forest System lands. All of the action alternatives have 

a net reduction in the number of wet meadows intersected by motorized roads and trails by 35 to 41 

percent.

OHV monitoring and field surveys conducted from 2003 through the 2007 field season identified

sites associated with existing National Forest System roads and trails in need of restoration or 

rehabilitation. Additional needs on both system and unauthorized routes were identified during Travel 

Management surveys. These sites are being prioritized and scheduled for restoration or rehabilitation as 

funding permits.

Ensure that culverts or other stream crossings do not create barriers to upstream or downstream passage 

for aquatic-dependent species. Locate water drafting sites to avoid adverse effects to in stream flows and 

depletion of pool habitat. Where possible, maintain and restore the timing, variability, and duration of 

floodplain inundation and water table elevation in meadows, wetlands, and other special aquatic 

features.

Consistency Determination: No culverts are being installed which could create barriers to upstream 

or downstream passage for aquatic-dependent species as part of this project. Any mitigation measures 

needed to assure passage for aquatic dependant species at low water crossings are included in Appendix A

(Site Specific Road, Trail and Open Area Information). Table I-7 displays the mitigation measures being 

required for specific stream crossings as part of this project.

SV-P5 At first crossing need to divert intermittent channel off route. The second crossing is a perennial 

crossing. The sediment at the perennial crossing is primarily tire wash and redistribution of fines 

within the channel. This crossing could use some additional gravel on both approaches to reduce 

the channel widening and sedimentation into this tributary to Haypress Creek.

Prior to activities that could adversely affect streams, determine if relevant stream characteristics are 

within the range of natural variability. If characteristics are outside the range of natural variability, 

implement mitigation measures and short-term restoration actions needed to prevent further declines or 

cause an upward trend in conditions. Evaluate required long-term restoration actions and implement 

them according to their status among other restoration needs.

Consistency Determination: All of the action alternatives improve relevant stream characteristics by 

reducing adverse impacts from roads and motorized trails. Table I-8 summarizes some of the key criteria 

used as indicators for improving relevant stream characteristics.

None of the alternatives propose new ground-disturbing activities. All of the action alternatives will 

reduce the amount of native-surface, motorized routes within RCAs and CARs by 27 to 33 percent. The 

action alternatives will also reduce the existing motorized stream crossings (perennial and intermittent) by 

27 to 30 percent.

RCO #2 - Standard and Guideline 103

Prevent disturbance to streambanks and natural lake and pond shorelines caused by resource activities 

(for example, livestock, off-highway vehicles, and dispersed recreation) from exceeding 20 percent of 

stream reach or 20 percent of natural lake and pond shorelines. Disturbance includes bank sloughing, 

chiseling, trampling, and other means of exposing bare soil or cutting plant roots. This standard does not 

apply to developed recreation sites, sites authorized under Special Use Permits and designated offhighway vehicle routes.

Consistency Determination: This Standard and Guideline does not apply to designated off-highway 

vehicle routes.

RCO #2 - Standard and Guideline 104

In stream reaches occupied by, or identified as “essential habitat” in the conservation assessment for, the 

Lahontan and Paiute cutthroat trout and the Little Kern golden trout, limit streambank disturbance from 

livestock to 10 percent of the occupied or “essential habitat” stream reach. (Conservation assessments 

are described in the record of decision.) Cooperate with State and Federal agencies to develop 

streambank disturbance standards for threatened, endangered, and sensitive species. Use the regional 

streambank assessment protocol. Implement corrective action where disturbance limits have been 

exceeded.

RCO #2 - Standard and Guideline 105

At either the landscape or project-scale, determine if the age class, structural diversity, composition, and 

cover of riparian vegetation are within the range of natural variability for the vegetative community. If 

conditions are outside the range of natural variability, consider implementing mitigation and/or 

restoration actions that will result in an upward trend. Actions could include restoration of aspen or other 

riparian vegetation where conifer encroachment is identified as a problem. 

Consistency Determination: This Standard and Guideline applies to vegetation management and is 

not applicable to this project.

RCO #2 - Standard and Guideline 106

Cooperate with Federal, Tribal, State and local governments to secure in stream flows needed to 

maintain, recover, and restore riparian resources, channel conditions, and aquatic habitat. Maintain in 

stream flows to protect aquatic systems to which species are uniquely adapted. Minimize the effects of 

stream diversions or other flow modifications from hydroelectric projects on threatened, endangered, and 

sensitive species.

Consistency Determination: This Standard and Guideline applies to stream flows and is not 

applicable to this project.

RCO #2 - Standard and Guideline 107

For exempt hydroelectric facilities on national forest lands, ensure that special use permit language 

provides adequate in stream flow requirements to maintain, restore, or recover favorable ecological 

conditions for local riparian- and aquatic-dependent species.

Consistency Determination: This Standard and Guideline applies to exempt hydroelectric facilities 

and is not applicable to this project.

RCO #3 - Standard and Guideline 108

Determine if the level of coarse large woody debris (CWD) is within the range of natural variability in 

terms of frequency and distribution and is sufficient to sustain stream channel physical complexity and 

stability. Ensure proposed management activities move conditions toward the range of natural variability.

Consistency Determination: The amount of coarse large woody debris in streams can be negatively 

affected by the amount of roads and trails near streams. All of the action alternatives reduce the amount of 

roads and motorized trails within RCAs and within RCAs. In addition all of the action alternatives 

prohibit cross country travel within RCAs. Therefore all of the action alternatives move conditions toward 

the range of natural variability in terms of coarse large woody debris. Table I-9 displays the key criteria 

associated with moving the level of coarse large woody debris conditions toward the range of natural 

variability.

None of the alternatives propose new ground-disturbing activities. All of the action alternatives will 

reduce the amount of native-surface, motorized routes within RCAs and CARs by 20 to 31 percent.

RCO #4 - Standard and Guideline 111

Design prescribed fire treatments to minimize disturbance of ground cover and riparian vegetation in 

RCAs. In burn plans for project areas that include, or are adjacent to RCAs, identify mitigation measures 

to minimize the spread of fire into riparian vegetation. In determining which mitigation measures to 

adopt, weigh the potential harm of mitigation measures, for example fire lines, against the risks and 

benefits of prescribed fire entering riparian vegetation. Strategies should recognize the role of fire in 

ecosystem function and identify those instances where fire suppression or fuel management actions could 

be damaging to habitat or long-term function of the riparian community. 

Consistency Determination: This Standard and Guideline is not applicable to this project.

RCO #4 Standard and Guideline 112

Post-wildfire management activities in RCAs and CARs should emphasize enhancing native vegetation 

cover, stabilizing channels by non-structural means, minimizing adverse effects from the existing road 

network, and carrying out activities identified in landscape analyses. Post-wildfire operations shall 

minimize the exposure of bare soil.

Consistency Determination: This Standard and Guideline is not applicable to this project.

RCO #4 Standard and Guideline 113

Allow hazard tree removal within RCAs or CARs. Allow mechanical ground disturbing fuels treatments, 

salvage harvest, or commercial fuelwood cutting within RCAs or CARs when the activity is consistent 

with RCOs. Utilize low ground pressure equipment, helicopters, over the snow logging, or other nonground disturbing actions to operate off of existing roads when needed to achieve RCOs. Ensure that 

existing roads, landings, and skid trails meet Best Management Practices. Minimize the construction of 

new skid trails or roads for access into RCAs for fuel treatments, salvage harvest, commercial fuelwood 

cutting, or hazard tree removal.

Consistency Determination: This Standard and Guideline is not applicable to this project.

Consistency Determination: No ground disturbing activities within suitable habitat for California 

red-legged frog, Cascades frog, Yosemite toad, foothill and mountain yellow-legged frogs, and northern 

leopard frog requiring Regional Stream Condition Inventory protocols are proposed for this project.

Prohibit or mitigate ground-disturbing activities that adversely affect hydrologic processes that maintain 

water flow, water quality, or water temperature critical to sustaining bog and fen ecosystems and plant 

species that depend on these ecosystems. During project analysis, survey, map, and develop measures to 

protect bogs and fens from such activities as trampling by livestock, pack stock, humans, and wheeled 

vehicles. Criteria for defining bogs and fens include, but are not limited to, presence of: (1) sphagnum 

moss (Spagnum spp.), (2) mosses belonging to the genus Meessia, and (3) sundew (Drosera spp.)

RCO #5 - Standard and Guideline 119

Locate new facilities for gathering livestock and pack stock outside of meadows and riparian 

conservation areas. During project-level planning, evaluate and consider relocating existing livestock 

facilities outside of meadows and riparian areas. Prior to re-issuing grazing permits, assess the 

compatibility of livestock management facilities located in riparian conservation areas with riparian 

conservation objectives. 

Consistency Determination: This Standard and Guideline is not applicable since livestock or pack 

stock facilities are not authorized with this project.

RCO #5 - Standard and Guideline 120 - Under season-long grazing:

• For meadows in early seral status: limit livestock utilization of grass and grass-like plants to 30 

percent (or minimum 6-inch stubble height). 

• For meadows in late seral status: limit livestock utilization of grass and grass-like plants to a 

maximum of 40 percent (or minimum 4-inch stubble height).

Determine ecological status on all key areas monitored for grazing utilization prior to establishing 

utilization levels. Use Regional ecological scorecards and range plant list in regional range 

handbooks to determine ecological status. Analyze meadow ecological status every 3 to 5 years. If 

meadow ecological status is determined to be moving in a downward trend, modify or suspend 

grazing. Include ecological status data in a spatially explicit Geographical Information System 

database.

Under intensive grazing systems (such as rest-rotation and deferred rotation) where meadows are 

receiving a period of rest, utilization levels can be higher than the levels described above if the 

meadow is maintained in late seral status and meadow-associated species are not being impacted. 

Degraded meadows (such as those in early seral status with greater than 10 percent of the 

meadow area in bare soil and active erosion) require total rest from grazing until they have 

recovered and have moved to mid- or late seral status.

Consistency Determination: This Standard and Guideline is associated with grazing and is not

Limit browsing to no more than 20 percent of the annual leader growth of mature riparian shrubs and no 

more than 20 percent of individual seedlings. Remove livestock from any area of an allotment when 

browsing indicates a change in livestock preference from grazing herbaceous vegetation to browsing 

woody riparian vegetation.

Consistency Determination: This Standard and Guideline is associated with grazing and is not 

applicable to this project.

RCO #6 Standard and Guideline 122

Recommend restoration practices in: (1) areas with compaction in excess of soil quality standards, (2) 

areas with lowered water tables, or (3) areas that are either actively down cutting or that have historic 

gullies. Identify other management practices, for example, road building, recreational use, grazing, and 

timber harvests that may be contributing to the observed degradation. 

Consistency Determination: OHV monitoring and field surveys conducted from 2003 through the 

2007 field season identified sites associated with existing National Forest System roads and trails in need 

of restoration or rehabilitation. Additional needs on both system and unauthorized routes were identified 

during Travel Management surveys. These sites are being prioritized and scheduled for restoration or 

rehabilitation as funding permits.

Critical Aquatic Refuges Standard and Guideline 123

Determine which critical aquatic refuges or areas within critical aquatic refuges are suitable for mineral 

withdrawal. Propose these areas for withdrawal from location and entry under U.S. mining laws, subject 

to valid existing rights, for a term of 20 years.

Consistency Determination: This standard and guideline is associated with mineral withdrawals and 

is outside the scope of this project.

Critical Aquatic Refuges Standard and Guideline 124

Approve mining-related plans of operation if measures are implemented that contribute toward the 

attainment or maintenance of aquatic management strategy goals.

Consistency Determination: This standard and guideline is associated mining plans of operation and 

is outside the scope of this project.

Appendix J: Roads Analyzed for Motorized Mixed Use

The following roads were brought forward to be analyzed for motorized mixed use (mixing highway-legal 

vehicles with non-highway-legal vehicles).

The analyses focused on the probability of a crash occurring and the severity of a mixed use crash

should one occur. Additionally, whether allowing motorized mixed use was consistent with the California 

Vehicle Code (CVC) was also determined. Key factors in assessing crash probability were traffic volume, 

types of vehicles and the presence of blind corners or other features that impaired visibility. Road 

characteristics leading to more severe crashes include steep side slopes and higher speeds. If a road is not 

rated as having both low accident probability and severity, then mitigation measures are needed. Such 

measures can be signs advising of mixed use and allowing the road surface to deteriorate to a rougher 

state, thereby reducing travel speeds.

Appendix K: Law Enforcement

Introduction ____________________________________________

U.S. Forest Service Law Enforcement and Investigations (LEI) personnel are responsible for protecting 

the public, employees, natural resources, and other property under the agency’s jurisdiction. Additionally, 

LEI investigates and enforces applicable laws and regulations that affect the National Forest System 

(NFS) lands, and prevents criminal violations. The new Travel Management Rule is one such regulation.

The Travel Management Rule requires designation of roads, trails, and areas open to motor vehicle 

use, and the prohibition of cross-country wheeled motorized vehicle travel by the public. This is a 

considerable change in public motorized access management from previous conditions where most 

Forests were managed as “open to cross-country travel.” The implementation of designated routes and 

areas for motorized vehicles will be the responsibility of all agency employees, especially in the area of 

education and enforcement. The law enforcement program is primarily responsible for issuing violations 

to the Travel Management Rule.

The National LEI budget is funded by appropriated dollars from Congress to provide law 

enforcement services on the NFS lands. The Travel Management program is one of many Forest programs 

to benefit from federal law enforcement funding. For the past few years, law enforcement funding has 

increased and that has translated into an increase in field law enforcement personnel1

To enhance enforcement of the Travel Management Rule, Region 5 Forest Recreation Programs have 

applied for and received grant dollars (green sticker funding) from the State of California Off-Highway 

Motor Vehicle Recreation Division Grants Program. These State funds are earmarked specifically for 

enforcement of off-highway vehicle laws and regulations on the various Forests, and are performed 

primarily by Forest Protection Officers (FPO). In addition, Law Enforcement Officers (LEOs) support the 

FPOs as needed, especially if serious violations have occurred. In recent years, State law enforcement 

grants have ranged from 3-4 million dollars annually with similar funding anticipated for the 2008-2009 

grant cycle.

.

Authority and Jurisdiction ________________________________

The Forest Service exercises its law enforcement authority when violation of laws or regulations occurs 

on NFS lands or when incidents affect the NFS. The existing authorities for enforcement are completely 

adequate and no new laws will be needed to implement the Travel Management rule.

The Tahoe National Forest has a law enforcement plan that is updated annually. All Forest Service 

employees have a duty to know and understand their authorities and responsibilities, and to properly 

enforce laws and regulations relating to the Forest within their authority and capability. LEI and agency 

personnel provide a regular and recurring presence on vast amounts of public land, roads, trails, and areas, 

and take appropriate action if illegal activity is discovered. Violations involving motorized vehicles are 

 1 Region 5 Law Enforcement budget figures for the past 4 years have increased and the number of law enforcement 

officers has increased by 65.

primarily enforced FPOs, which patrol off-highway use roads, trails, and areas. These include violations 

such as operating a motor vehicle in violation of federal regulations and California vehicle code, parking 

improperly, resource damage to soils, vegetation or wildlife, and disorderly or unruly behavior. LEOs

have discretion when deciding what type of action to initiate when handling violations to the following 

federal laws that pertain specifically to motor vehicle use.

• The Act of June 4, 1897 (Title 16 United States Code 551) is the authority for issuing regulations 

at Title 36 Code of Federal Regulations, Part 261 (36 CFR 261). Specific OHV travel management 

regulations are in sections 261.9 – Property, 261.13 –Motor Vehicle Use, and 261.15 –Use of 

Vehicles Off-Road. These CFRs cover a wide array of misdemeanor infractions. 

• The Act of March 3, 1905 (Title 16 United States Code 559) authorizes all employees of the Forest 

Service to make arrests for violation of the laws and regulations pertaining to National Forests.

Normally, arrest authority is limited to trained law enforcement personnel. (Any employee may 

take immediate action when necessary to protect life and prevent serious damage to or destruction 

of property, escape of a suspect, or loss of material evidence when such action can be done with 

reasonable safety.)

Cooperation____________________________________________

The Forest Service shares responsibility and cooperates with local, State, and other Federal agencies in 

the execution of its law enforcement program. The authority for cooperation among agencies, especially 

as it pertains to Travel Management, is within the following laws:

• The act of August 10, 1971 (Title 16 United States Code 551a) authorizes the Secretary of 

Agriculture to cooperate with, and provide reimbursement to, any State or political subdivision 

thereof, for the enforcement of their laws within NFS. This law does not deprive any State or local 

law enforcement agency from exercising its criminal and civil jurisdiction on lands that are part of 

the NFS. 

• The California Penal Code, Section 830.8 provides that Forest Service law enforcement personnel 

may exercise State Peace Officer authority where the sheriff of the county wherein the officer 

works has provided specific written permission for the officer.

• The State vehicle code section 38301 allows State law enforcement officer to enforce any of the 

Federal CFRs related to motor vehicles on NFS lands.2

Each Forest maintains close working relationships with many State and local law enforcement 

agencies that have law enforcement responsibilities within/and or adjacent to the Forest boundary. 

Significant cooperating agencies relative to the Travel Management Rule include the local county sheriff 

departments, the California Department of Fish and Game, California Highway Patrol, California 

Department of Forestry and Fire Protection, and occasionally one or more Federal agencies depending on 

 2 State Vehicle code section 38301. (a) It is unlawful to operate a vehicle in violation of special regulations which 

have been promulgated by the governmental agency having jurisdiction over public lands, including, but not limited 

to, regulations governing access, routes of travel, plants, wildlife habitat, water resources and historical sites.

the violation. Forest Service law enforcement personnel cooperate fully with these agencies in carrying 

out their law enforcement responsibilities by providing assistance; liaison, advice, and information.

Forests maintain Cooperative Law Enforcement Agreements with their respective county sheriff’s 

office. In Region 5, the total cost for the 2008 Cooperative Law Enforcement Agreements is $891,397.3

• Supplemental patrols in areas of high use.

These dollars are for performance of duties in addition to the normal activities in which the sheriff’s 

deputies handle crimes against persons and their property that may occur within the NFS boundary. In 

these agreements, both parties recognize that public use of NFS lands is usually located in areas that are 

remote or sparsely populated and the enforcement of State and local law is related to the administration 

and regulation of NFS lands. Within the Cooperative Law Enforcement Agreements, an Operating Plan is 

developed outlining the supplemental work to be performed by the cooperating agency. Relative to the 

Travel Management Rule, operating plans may provide:

• Supplemental patrols on weekends or during particular months of high use.

• Additional officers for large group gatherings or events (enduros)

• Vehicle checkpoints for vehicle registration spark arrestors, and other miscellaneous items.

Implementation and Tracking _____________________________

Implementation of the Forest Service law enforcement program is continually adapting as law 

enforcement personnel assess the changing patterns of visitor use and attitudes, and the trends in 

violations, especially for property and resource damage. One method of assessment is the analysis of Law 

Enforcement and Investigations Management Attainment Reporting System (LEIMARS) data. LEIMARS 

tracks all known violations of criminal law or regulation on NFS lands (FSH 5309.11, chapter 40 and 

FSM 5340). Additionally, imbedded in LEIMARS is the Case Tracking System, which tracks all felony 

and serious misdemeanor cases. These tracking systems:

• Capture and record information on location, volume, damages, and type of violations occurring on 

NFS lands.

• Provide a retrieval system of data on incidents and violations that is responsive to the needs of all 

organizational levels. 

• Provide agency managers with a means to identify and monitor law enforcement activities.

• Specifically identify problem areas and periods of activity. 

• Provide a method to record and analyze incidents involving violations or suspected violations on 

NFS lands.

Trends in violations related to the Travel Management Rule can be analyzed and appropriate action(s) 

taken, if needed. Appropriate action(s) may involve one or more techniques or adaptive strategies. In the 

law enforcement community, this is often referred to as the “three E strategy” of engineering, education, 

and enforcement. With the change in the Travel Management Rule, it is anticipated that the law

K-4 – Tahoe National Forest

enforcement program will use a combination of strategies, especially during the first five years of the rule 

implementation.

Implementation Strategy 

(Engineering – Education – Enforcement) ___________________

The Engineering strategy is designed to prevent or reduce inadvertent violations, resource damage, and 

crime vulnerability. The strategy’s goal is to remove the opportunity to commit a violation. LEI personnel

work with each Forest, particularly the recreation and engineering programs, to implement some or all of 

the following specific tactics:

• Proper design of improvements and facilities.

• Facility security measures such as installation of barricades, gates, and other natural obstacles.

• Forest signing, both directional and informational, to assist the public to ensure they stay on 

designated trails, and out of the wilderness and other sensitive areas.

• Physically close and rehabilitate decommissioned roads and trails.

The Educational strategy focuses on specific user groups, school groups, recreation users, and the 

public. The goal is to develop responsible and concerned public land use attitudes in forest users; it’s 

violation prevention. Forest LEOs and FPOs make regular contacts in the field informing the users of the 

regulations and need for the prohibition. The LEI personnel work with each Forest, particularly the 

recreation and public information programs, to identify and implement some or all of the following 

specific tactics.

• Have motor vehicle use maps easily available to public.

• Have route numbers visually marked on the ground.

• Distribute maps and brochures promoting responsible use.

• Conduct environmental interpretation activities in local communities, at schools, and with special 

interest groups.

• Use of all forms of the media (television, radio, and newspapers), especially prior to, and during, 

the high use periods. 

• Ensure all employees understand the Travel Management Rule.

• Utilize high visibility prevention patrols and public information checkpoints, especially during the 

peak use periods. 

• Encourage cooperating law enforcement agencies to make visitor contacts and provide violator 

information to Forest Officers. 

• Ride with other agency officers to demonstrate solidarity to the public.

• Issue news releases of arrests and successful prosecutions, including offender names, criminal 

penalties, and court ordered restitution.

The Law Enforcement strategy is to affect crime prevention measures that are designed to reduce 

specific criminal activity, deter potential and repeat offenders, maximize enforcement actions and 

visibility, and increase prosecutorial successes. All enforcement actions should result in a better

Appendix K: Law Enforcement

Tahoe National Forest – K-5

understanding of regulations pertaining to the management of NFS lands. LEI personnel work with each 

Forest, to identify and implement some or all of the following specific tactics:

• Schedule officers to work during the identified problem periods, including holidays and weekends.

• Utilize high profile “saturation patrols” and stationary surveillance posts in the identified problem 

areas.

• Utilize the most effective and efficient means of patrol, including foot, horseback, all-terrain 

vehicle, snowmobile, watercraft, and aircraft.

• Aerial over-flights to enforce restriction under Travel Management Rule. 

• Enlist the aid of volunteers.

• Initiate an awards program.

• Supplement patrols with cooperating law enforcement agencies in areas of concern.

• Use technical investigative equipment (cameras, monitors, sensors) to assist officers with 

detecting and monitoring violations at known or suspected violation sites.

• Conduct planned and approved compliance checkpoints.

• Follow-up on complaints to document violations, damages, and identify suspect vehicles or 

persons.

• Require cooperating law enforcement agencies to assist with reporting and/or enforcing violations 

within their authority.

• Patrol with other cooperating law enforcement agency officers.

• Conduct unpredictable patrol schedules.

• Conduct special enforcement actions (unmarked vehicle deployment, surveillance, traffic checkpoints).

• Utilize LEIMARS and Central Violations Bureau databases along with the State motor vehicle 

data, to identify repeat offenders for enhanced prosecution. 

• Pursue court ordered restitution or civil collections for resource and property damages.

• Encourage prosecutorial and judicial support.

• Execute bench warrants related to off-highway vehicle violations.

Assumptions ___________________________________________

Based on many years of enforcing off-highway vehicles, implementation of the Travel Management Rule 

from a law enforcement perspective assumes the following to be true. Additionally, these assumptions are 

based on several case studies in R5. These assumptions may change in time with analysis of the 

LEIMARS database.

Enforcement Assumptions:

• Enforcement of the laws and regulations related to Travel Management will be enforced equally in 

authority and weight as with all other Federal laws and regulations.

• As with any change in a regulation on NFS lands, there is usually a transitional period for the 

public to understand the changes. It is anticipated there will be a higher number of violations to

Appendix K: Law Enforcement

K-6 – Tahoe National Forest

the Travel Management Rule the first few years and the number of violations will decline as the 

users understand and comply with the rules. It is assumed:

§ Users in communities adjacent to the Forest will comply within 1-2 years.

§ Frequent users but further in distance from the Forest will comply within 2-3 years.

§ Infrequent users regardless of distance may take up to 5 years to comply.

• Law enforcement officer and agency personnel’s presence and enforcement actions will positively 

affect OHV users’ behaviors and attitudes.

• The Travel Management Rule and associated motor vehicle use map clearly define the designated 

routes; therefore, making violations to the rule unequivocal.

• Once the motor use vehicle map is published, the implementation of the established 

dedicated network of roads, trails, and areas with signs, and user education programs, will 

reduce the number of violations.

• FPOs spend a large percentage of their time on Travel Management issues, and depending on the 

Forest the estimate range from 30 to 50 percent. LEOs spend approximately 10-20% of their time 

on enforcement of off-highway vehicle issues.4

Agency Funding Assumptions:

• Appropriated program funding levels and number of law enforcement personnel does not affect 

enforcement of the Travel Management Rule. All laws and regulations are enforced equally.

• Appropriated funds will remain level or increase slightly in the next five years.

• The State of California Off-Highway Motor Vehicle Recreation Division Grants Program (green 

sticker funding) enhances and provides additional law enforcement presence in the field at the 

Forest level.

Public Attitude and Compliance Assumptions:

• Forest users want to do the right thing and will obey the rule5

• User compliance

, once they understand the rule and 

motor vehicle use map.

is based on the State of California Off-Highway Motor Vehicle Recreation 

Division data and is anticipated to be:

§ 2-3% of the users think about and may violate a law.

§ 1-2% of the users will violate the law.

SVRA visitors divided by the 210,000 citations written, is approximately 5 percent non-compliant, and 95% 

compliant.

Measures of Success ____________________________________

Measuring the success of the Travel Management Rule from a law enforcement perspective will be done 

using the LEIMARS database. An analysis of the data may alert a Forest to a particular problem area for 

violations such as a group campsite area that may be surrounded by flat meadow areas inviting riders to 

potentially violate the regulation. A successful program will see a positive change in the following measures:

• Measure 1: A reduction in the number of off-route travel violations.

• Measure 2: A reduction in the number of resource damage violations.

Green, Yellow, Red Field Surveys

Using the soil erosion risk ratings found in the Soil Resource Inventory (See Chapter 3.02, Table 3.02-8), 

82 percent of the Forest has a high to very high erosion hazard. The inherent risk of erosion of the soils 

within the Tahoe National Forest (TNF) was refined using the Ecosystem Management Decision Support 

Model (EMDS). The parameters used in the EMDS model to assess soil erosion risk were 1) presence of 

geo-debris slides, 2) soil erodibility, 3) slope, and 4) precipitation. The EMDS model compared the K 

factor, percent slope, precipitation, and presence of geodebris slides of each route segment (~300 meters) 

to all other road and motorized trail segments on the TNF. The result is a relative erosion risk value 

assigned between 0 (highest risk) and 1 (lowest risk) for each 300 meter segment of every road and 

motorized trail. The EMDS scores for the length of roads and motorized trails in each HUC6 watershed 

were averaged to define the potential erosion risks on the watersheds on the TNF. The modeled erosion is 

generally higher on much of the west slope of the TNF. This is due to the steeply sloping topography of 

many of the watersheds, the potential presence of geo-debris slides, higher precipitation values, and finertextured, more erosive soils. The modeled risk is lower on the east-side of the TNF due to coarser textured 

soils and less steep slopes. Site specific erosion risks for these routes are displayed below.

Monitoring Strategy ___________________________________

Monitoring is critical for evaluating the effectiveness of management decisions and the accuracy of 

analysis assumptions and conclusions. Monitoring of road and trail conditions is required, and must meet 

regional and/or national standards. If monitoring determines additional resource damage is occurring, 

steps to prevent further damage may be taken. If the mitigations are not effective or are not possible, 

additional road or trail closures may be required and would require additional NEPA analysis.

Proposed route-specific monitoring varies by alternative. As identified in Appendix A (Site Specific Road, 

Trail and Open Area Information), resource specialists have identified approximately 88 routes where 

site-specific monitoring would be needed if the routes are added to the system for public use in an action 

alternative. These include monitoring effects of the routes on botany, heritage, watershed, and lands and

recreation resources. In some cases, one route may be monitored to assess conditions of multiple 

resources.

In addition to effectiveness monitoring related to the actions of this project, many other forms of 

monitoring and data collection take place on the Forest. These include ongoing monitoring that is already 

prescribed, such as surveys of roads and trails for infrastructure condition, monitoring of cultural resource 

sites, noxious weed spread, rare plants, or wildlife surveys. Some of this monitoring may directly or 

indirectly assess the effects of roads or trails on resources, as well as generally assessing conditions of 

roads for stability and maintenance. While these monitoring efforts are not prescribed in this Travel 

Management EIS, these data would also be used whenever possible, in assessing either the effectiveness 

of the actions proposed or in adjusting future travel management actions.

The Forest Service will conduct annual implementation monitoring for the specific resource concern 

associated with that route if included in the selected alternative. Routes to be monitored are listed in this 

Appendix M (OHV Monitoring) in Table M-1 and summarized in Table M-2. Results of the OHV 

monitoring will be incorporated in the annual Forest Plan Monitoring and evaluation report. This report 

will be made available on an annual basis.
