According to the 1987 photorevised U.S. Geological Survey "Manteca, California, East" 7.5-Minute Topographic Quadrangle Map, the property has an elevation of approximately 40 feet above mean sea level. However, the topography of the site varies extensively. According to a December 1996 topographic survey of the site by RLC Associates of Manteca, the site has an elevation ranging from 38 to 68 feet above mean sea level. The overall former Spreckels Sugar Plant No. 2 property includes approximately 362 acres of property which were annexed to the City of Manteca. The project site is currently a non-operating sugar beet processing plant with associated former cattle yards, orchards, and waste ponds. Most of the factory's surface structures have been razed. This area of the project site is being redeveloped for industrial use. The site is bounded on the north by Yosemite Avenue, on the south by California State Highway 120 Bypass, on the west by Powers Avenue and residential development and on the east by California State Highway 99. The land use in the site vicinity is characterized as mixed use, retail, light commercial, agricultural and residential property. 2.0 GEOLOGY AND HYDROGEOLOGY The site lies within the Great Valley Geomorphic Province of California. The valley is approximately 400 miles long and averages about 50 miles wide, and comprises about 20,000 square miles. The valley has been filled with a thick sequence of marine and non-marine sediments from the late Jurassic to Holocene. The uppermost strata of the Great Valley represent, for the most part, the alluvial, flood, and delta plains of two major rivers (Sacramento and San Joaquin Rivers) and their tributaries. The valley deposits are derived from the Coast Ranges to the west and the Sierra Nevada to the east. Granitic and metamorphic rocks outcrop along the eastern and southeastern flanks of the valley. Marine sedimentary rocks outcrop along most of the western, southwestern, southern, 20-YPO-273/2000P331/2000W034 Page 2 of 11 Copyright 2000,Kleinfelder,Inc. September 4,2000
