The site is located in the eastern half of subsections C and <br /> F, and the western half of subsection G, of Section 36, Township 4 North, Range 6 <br /> East, MDB&M. <br /> 2.2 CURRENT USE AND SITE CHARACTERISTICS <br /> The site currently consists predominantly of relatively level agricultural cultural #fields, with <br /> several farm roads crossing the site from north to south and from east to west. A trailer <br /> home and a barn are located near the southern portion of the site, north of Eight Mile <br /> 1 Road and east of Interstate 5 (1-5). Another farmhouse and barn is located west of 1-5 <br /> near the central portion of the site. Irrigation systems are located throughout the <br /> property. Several overhead power lines are located along the boundaries and across <br /> ' the site. A golf course is located in the southwest corner of the site. The site is <br /> bounded by Eight Mile Road to the south, Thornton Road to the east, and agricultural <br /> fields to the north and west. The project area is centrally divided by 1-5 from north to <br /> south. <br /> 2.3 REGIONAL GEOLOGY AND HYDROGEOLOGY <br /> The site lies within the central potion of the Great Valley Geomorphic Province of <br /> California. The valley is approximately 400 miles long and averages about 50 miles <br /> wide, and comprises about 20,000 square miles. The valley has been filled with a thick <br /> sequence of marine and non-marine sediments from the late Jurassic to Holocene. <br /> The uppermost strata of the Great Valley represent, for the most part, the alluvial, flood, <br /> and delta plains of two major rivers (Sacramento and San Joaquin Rivers) and their <br /> tributaries. <br /> The valley deposits are derived from the Coast Ranges to the west and the Sierra <br /> Nevada to the east. Granitic and metamorphic rocks outcrop along the eastern and <br /> southeastern flanks of the valley. Marine sedimentary rocks outcrop along most of the <br /> western, southwestern, southern, and southeastern flanks; and volcanic rocks and <br /> deposits outcrop along the northeastern flanks of the valley. The valley geomorphology <br /> includes dissected uplands, low alluvial plains and fans, river flood plains and channels, <br /> and overflow lands and lake bottoms.
