**CALIFORNIA TURF**

[]{.mark}

This scenario is intended to represent turf areas (golf courses, parks,
sod farms, and recreational fields) in central/northern California. Golf
courses and turf farms generally both apply pesticides, however for this
scenario parameters were selected to represent golf courses.
Consultation with University of California Cooperative Extension (D.
Haver, personal communication) indicated that parameterzing the scenario
as golf course turf would generally be most conservative due to steeper
slopes and proximity of golf courses to surface water resources (a
majority of turf farms are located in the desert). Analyses were
conducted within a refined area of interest (AOI) where there is a high
density of golf courses, precipitation is expected to be high, and
irrigation is common (Figure 1).

The most common turfgrass used for athletic fields, parks, and golf
courses in California is common bermudagrass (Cynodon dactylon). Other
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.), kikuygrass (*Pennisetum clandestinum*), St.
Augustinegrass (*Stenotaphrum secundatum*), zoysiagass (*Zoysia
japonica*), and dichondra (*Dichondra micrantha*). Crop parameters for
this scenario are based primarily on bermudagrass (*Cynodon* spp.) since
it is a primary turf grass for golf courses and athletic fields. Common
bermudagrass is drought tolerant and well adapted to sunny conditions.
It is a medium, coarse-textured grass with a gray green color, but it
becomes dormant and loses its color in cold weather. Common bermudagrass
establishes a deep root system and produces long rhizomes and stolons.
Common bermudagrass is planted in the spring or summer at a rate of 1 lb
seed/1000 sq. ft. Common bermudagrass requires frequent mowing to
maintain an attractive quality. It has good wear quality when it is
growing, but produces heavy thatch and can produce thatch in light
traffic areas (UCIPM, 2003). There are new seeded cultivars of common
bermudagrass that have improved turfgrass quality characteristics.
Within the vicinity of the AOI, bermudagrass is a common turf grass for
golf courses, (Darren Haver, Watershed Management Advisor, UC
Cooperative Extension). Bermudagrass grows on a wide variety of soils,
from heavy clays to deep sands; tolerating acidic, alkaline and saline
conditions. Bermudagrass does best on well-drained sites. Bermuda grass
can survive low fertility conditions but requires high nitrogen
concentrations for production of good quality turf (Duble 2004).

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.

Reliable and detailed spatial data regarding the locations and extent of
golf courses in the Bay Area are unavailable. In the absence of detailed
data, a coarse analysis of golf course locations with respect to STATSGO
soils was performed using soils data from NRCS (USDA, 2006a) and the
golf locales coverage obtained from Environmental Systems Research
Institute, Inc. (ESRI, 2005). Soils were selected based on the overlap
between golf courses in the AOI. Based on a geospatial analysis of soils
(USDA 2006) and golf course locales (ESRI 2005), Capay soils were chosen
to represent turf in the AOI (Table 5).

[]{.mark}

Based on the soils analysis, approximately 35% of the soils overlapping
golf course locales are in hydrologic group D. The Capay series was
chosen to represent turf areas in the AOI (Table 5) because it is a one
of the most common hydrologic group D soils co-located with golf
courses, is among the most erodible, and includes the maximum slope on
which golf courses are located (D. Haver, personal communication). Capay
soils are in Hydrologic Group D soils and are located on the western
edge of the Sacramento Valley and intermountain valleys of the Coast
Range of northern California. The soil is extensive in MLRA-17 and has
been mapped in MLRA 14 in some places (USDA, 2006b). Clear Lake soils
(also widespread) were not used for scenario parameterization since the
USLEK (0.174 -- 0.24) is significantly lower than Capay. Capay soils
co-located with golf course locales in the AOI have a USLE K factor of
0.17 to 0.37 which includes the 90^th^ percentile of these soils in
erodibility (Table 5). The Capay series is Fine, smectitic, thermic
Typic Haploxererts. Capay soils are on alluvial fans, alluvial flats,
interfan basins and basin rims with slopes ranging from 0 to 9 percent.
(USDA 2006). Capay soils have an A horizon from 0 to 5 inches (0 to 13
cm) deep and a B horizon from 5 to 62 inches (13 to 157 cm) deep (USDA,
2006).
