k" KLEINFELDER 2 SITE SETTING 2.1 SITE LOCATION The site is located in the eastern and western portion of sections 16 and 28, respectively, of the Compo De Los Francesses Grant of Township 2 North Range 6 East of the Mount Diablo Baseline and Meridian. According to the 1976 photorevised US Geological Survey "Lodi South, California," 7.5-Minute Topographic Quadrangle Map, the property has an elevation of approximately 20 feet above mean sea level. The site includes the immediate vicinity of the intersection of March Lane and the Union Pacific Railroad in Stockton, California. 2.2 CURRENT SITE USE AND VICINITY CHARACTERISTICS The project site is surrounded by residential development to the southwest and commercial development in the remaining directions. March Lane and Union Pacific Railroads are currently active. 2.3 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 represents, 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, and southeastern flanks; and volcanic rocks and deposits outcrop along the northeastern flanks of the valley. The valley geomorphology includes dissected uplands, low alluvial plains and fans, river flood plains and channels, and overflow lands and lake bottoms. 20-3712-08.E01/2018R510 Page 3 of 16 © 1998,Kleinfelder, Inc.
