**CALIFORNIA RESIDENTIAL SCENARIO**

[]{.mark}

This scenario is intended to be used as a surrogate for all
urban/suburban home and residential uses in the San Francisco Bay area
of California (Figure 1). The area of interest (AOI) was selected based
on the high degree of residential development (Figure 1) within the Red
Legged frog habitat, and the generally wetter climate of the San
Francisco Bay Area, relative to southern California. The intention is to
couple the edge of field concentrations from this scenario with the edge
of field concentrations from the impervious surface scenario for San
Francisco to generate weighted concentrations for areas of varying
impervious cover. Based an a 2002-2003 survey of northern California
(Arcade Creek/Sacramento, Five Mile Creek Slough/Stockton, and San
Francisco Bay areas), about 60% of residential pesticide uses were
applied to hard surfaces such as sidewalk, walls, or foundations).
Approximately 20% were applied to lawns and 20% to ornamental plantings.
The remaining was applied to vegetable gardens, edible plants, or fruit
trees (Flint, 2003). Approximately 83% of these were applied by the
homeowners' themselves. Approximately 17% of homeowners hired an outside
professional to apply the pesticides.

[]{.mark}

Crop parameters have been chosen to reflect residential turf areas,
primarily lawns, within the AOI. The major species used for turfgrass in
California include Bentgrass (Agrostis spp.), Kentucky bluegrass (Poa
pratensis), ryegrass (Lolium spp.), tall fescue (Festuca arundinacea),
fine fescues (Festuca spp.), common bermudagrass (Cynodon dactylon),
kikuygrass (Pennisetum clandestinum), St. Augustinegrass (Stenotaphrum
secundatum), zoysiagass (Zoysia japonica), and dichondra (Dichondra
micrantha). The most common grass in residential areas includes tall
fescue. Tall fescue is a cool-season grass, well adapted to sunny or
partially shady areas. When densely sown, a pure stand forms a moderate
to coarse-textured lawn that is uniform in appearance with good weed and
disease resistance. Tall fescue tolerates warm summer temperatures and
stays green during cool, but not severe winter conditions. New varieties
that are finer in texture and shorter in stature are known as turf-type
tall fescues and dwarf turf-type tall fescues. Tall fescue is a good
species to plant for general lawn use and is the most common lawn grass
in California (UCIPM, 2003). Residential Lawns are irrigated year round,
even during the wet season. Northern/Central California however is
implementing best management practices to reduce irrigation during the
wet season (Darren Haver, personal communication).

Metfile W23234 was selected for this scenario since it is the closest
metfile to San Francisco. Its data were collected in San Francisco, CA.
The station is located approximately 2 meters above mean seal level
(AMSL). San Francisco receives approximately 20 inches of rainfall
annually with nearly 60% of the annual precipitation occurring in
January, February, and March (NOAA, 2006). This station is the closest
available weather station that includes data required for PRZM.

[]{.mark}

Soils were selected based on vulnerability and the extent of overlap
within urban areas for central/coastal California based on land use data
from the California Department of Forestry and Fire Protection (Figure
1). Urban areas are largely based on census blocks of over 500 people
per sq. mile (CDF-FRAP, 2005a). The data developers indicate the
coverage provides the statewide \"urban footprint\" from a consistent
data source, useful for analyzing growth and associated impacts. The
data are most useful for statewide or regional studies (CDF-FRAP,
2005a). According to data from the CDF-FRAP development footprint
(CDF-FRAP, 2005b), this relates to about 1 or more housing units per 5
acres to greater than 1 housing unit per 1 acre. Based on a geospatial
analysis of soils (USDA 2006a) and land use data (CDF-FRAP, 2005) for
urban areas as well as conversations with local extension agents, Tierra
soils were chosen to represent residential areas in the AOI (Table 5).
The soils are of moderate extent and are generally located in areas
within 30 miles of the coast in central and south-central California
(USDA, 1997). Tierra soils are gently sloping to steep and are on
dissected terraces and low hills at elevations of 100 to 1,200 feet.
Slopes range from 2 to 50 percent (USDA, 1997). The geospatial analysis
indicates that Tierra soils are the fourth most common D soil on which
residential dwellings are located (Table 5), accounting for 2% of all
soils in residential areas (USDA 2006a; CDF-FRAP, 2005a).

Three hydrologic group D soils are more common than Tierra soils (Table
5), however they were not chosen for modeling for several reasons. San
Joaquin soils are located in the Sacramento valley. Based on NOAA
weather data, the Sacramento valley receives several inches less
precipitation than the Bay area (e.g., San Francisco). Secondly, Clear
Lake soils are often found in basins and drainage ways which are not
generally expected to contain residential development (USDA, 2006b.
Third, Jacktone soils are significantly less erodible (USLE K = 0.24)
than Tierra soils (USLE K 0.32 -- 0.42).

[]{.mark}

The Tierra series represents the 90^th^ percentile of vulnerability in
drainage, and erodibility. It is found on a range of slopes, including
the maximum slope of this scenario. These soils are Fine, smectitic,
thermic Mollic Palexeralfs which consists of deep soils formed in
alluvial materials from sedimentary rocks (USDA 1997). Tierra is a
Hydrologic Group D soil which account for approximately 40% of urban
soils in drainage. Tierra soils located in urban areas within the AOI
have a USLE K factor of 0.32-0.43 which includes the 90^th^ percentile
of these soils in erodibility (Table 5). Corresponding slopes range from
5 to 50 percent (Table 5).
