III. Environmental Setting, Impacts,and Mitigations F. VEGETATION AND WILDLIFE SETTING Site Description The proposed project site,consisting of approximately 218.5 acres on threeP arcels,is located southeast of the City of Stockton, San Joaquin County,California(Stockton East 7.5'U.S. Geological Survey[USGS] quadrangle). Located on the floor of the Central Valley,the site's topography is relatively flat,ranging in elevation from 30 to 40 feet above MSL(mean sea level). The first parcel (CYA property)encompasses approximately 126.4 acres located immediately north of the existing City of Stockton landfill. The second parcel (Brocchini property) encompasses approximately 85.6 acres located immediately southeast of the existing landfill. The Brocchini property is separated from the existing landfill by the North Branch of the South Fork of Little Johns Creek(on-site). The third parcel(also CYA property,but for purposes of this document will be referred to as the triangular property)is approximately 6.5 acres and located in the northeast corner,between Austin Road,the landfill access road, and the Brocchini property. The proposed expansion parcels, as well as other properties in the immediate vicinity, primarily consist of existing or former agricultural lands. Surrounding land uses include the Forward,Inc. Landfill to the south of the Brocchini property, a California Youth Authority (CYA)facility to the north of the CYA property, and agricultural lands and associated residences along the remaining property boundaries. Although the proposed expansion site has been disturbed through historic and/or on-going agricultural uses,the site provides potential habitat for special status species occurring in the region,discussed below. Additionally,on-site drainages are afforded protection under Section 404 of the Federal Clean Water Act and Sections 1601-1603 of the Fish and Game Code, also discussed below. Finally,local biological resource conservation policies have also been adopted by San Joaquin County and the City of Stockton.
