RECLAMATION PLAN I. DESCRIPTION OF ENVIRONMENTAL SETTING The project site is located in the southern portion of San Joaquin County near the intersection of Interstates 5 and 580. The project encompasses approximately 500 acres within the northern triangle of the intersection. The city of Vernalis is approximately 5 miles to the northeast of the project. Present land use in the area include mining, agricultural and open spaces. The land surface and native vegetation in this area have been extensively disturbed by past shallow mining excavations in the stream channel and by overgrazing of livestock. A. Maps - See Attached B. Geology The project site is located in the Resources Sectors C2, C3 , C4 , and B3 as defined in the SMARA EIR #9, Designation of Regionally Significant Construction Aggregate Resources in the Stockton-Lodi Production Consumption Region. Resource Sector C covers a 900 acre portion of the alluvial fan formed by Hospital Creek along the western edge of the valley. The fan is on the eastern flank of the Diablo Range and was formed by streams flowing north-eastward from the base of the mountains . The material in the fan is composed of San Luis Ranch alluvium and Los Banos alluvium, which contain reworked sediments derived from older alluvial fan deposits . The unit is approximately the same age as the late Pleistocene Modesto and Riverbank Formations that occur on the east side of the Valley in the Sierran Foothills . The course clasts are largely composed of metagraywacke, chert, and quartz with smaller amounts of quartzite, schist, sandstone, basalt, and andesite. Maximum rock size in this material is 10 inches with approximately 40 percent in the plus one inch size range . C. Hydrology: Water for the plant is recycled. Make-up water is provided by an existing well that pumps at a rate of approximately 500 GPM. There will be no changes in water requirements as a result of this application. No watersheds will be disturbed. E. Vegetation/Wildlife: The property was surveyed as part of the 1993 Draft EIR Habitat Conservation Plan San Joaquin Kit Fox Western San Joaquin County. Extensive discussions relating to vegetation, wild life and climate of the area are to be found therein. No direct evidence of Kit Fox was found on the subject property. t E
