'• KLE FELDER - 3 SITE SETTING ITE LOCATION 1 :o Site is located at the southeast comer of Filbert Avenue and Myrtle Streets in California (see Plate 1). The address of the site is 110 Filbert Street, Stockton, a. The site is located in Section 6 (extrapolated), Subsection M, Township 1 North East, Mount Diablo Base and Meridian. EGIONAL GEOLOGY AND HYDROLOGY lies within the Great Valley Geomorphic Province of California. The valley is Lately 400 miles long and averages about 50 miles wide, and comprises about 20,000 Liles. The valley has been filled with a thick sequence of marine and non-marine s from the late Jurassic to Holocene. The uppermost strata of the Great Valley s, for the most part, the alluvial, flood, and delta plains of two major rivers (Sacramento oaquin Rivers) and their tributaries. y deposits are derived from the Coast Ranges to the west and the Sierra Nevada to the critic and metamorphic rocks outcrop along the eastern and southeastern flanks of the vlarine sedimentary rocks outcrop along most of the western, southwestern, southern, Leastem flanks; and volcanic rocks and deposits outcrop along the northeastern flanks of f. The valley geomorphology includes dissected uplands, low alluvial plains and fans, d plains and channels, and overflow lands and lake bottoms. ific geologic information was obtained from a document prepared for Del Monte by .ill titled, "Additional CPT Investigation and Monitoring Well Installation Report, Del isco Property, Stockton, California" (dated March 2002), and past documents pertaining tallation of other monitoring wells on the site. According to the CH2M Hill reports, the derlain by unconsolidated alluvial sediments. The soils encountered during subsurface :ions show clay, silt, sand, and gravel. The predominant soils are interbedded sandy silty sand. The majority of the native sediments near the site consist of Miocene to continental rocks and deposits of a heterogeneous mixture of interbedded, generally rted clay, silt, sand and gravel. ,el information was also obtained from the CH2M Hill groundwater reports. Generally, a period of the monitoring (1995 to date) the groundwater elevation beneath the project leen -20 feet in reference to mean sea level (msl). The direction of groundwater flow predominantly to the southeast. Historical groundwater information obtained by CH2M ates that in 1991 groundwater elevation beneath the site was approximately-53 feet msl 'ection of groundwater flow to the northwest.
