8 2.0 EXISTING CONDITIONS Regional Setting The 111-acre Spotorno Ranch project site is located within the City of Pleasanton (Figure 1) in the Livermore 7.5” U.S. Geological Survey (USGS) quadrangle (Figure 2). The approximately 28 to 30-acre development area is bound by Alisal Street to the west and south, Westbridge Lane to the southeast, agricultural fields and residences to the north, and open rangelands to the east. The site is used primarily as agricultural lands for growing hay and as rangeland for cattle. Topographically, the western portion of the site is fairly level at approximately 380 feet (116 meters) with an increase in slope towards the eastern edge to approximately 480 feet (147 meters) National Geodetic Vertical Datum (NGVD). Surrounding land uses are primarily open space/agricultural (i.e. rangeland), residential, golf course, and major and minor roadways. Four soil-mapping units have been identified on the site and these soils are described in greater detail in Table 1 and depicted in Figure 3. None of the soils of the site are considered hydric soils, i.e. soils that under appropriate hydrological conditions may support wetlands, however, hydric inclusions may occur. All of the soil types of the project site are considered well-drained. None of the soils of the site is a serpentine or alkaline soil, therefore, they would not be expected to support special status plant species that are endemic to serpentine or alkaline soils.
