' I <br /> i <br /> Dividend Development company July 2.2, 1991 <br /> Report of Findings - North Parcel Page 5 <br /> GEOLOGY: <br /> The Dividend site is located on the west side of the San Joaquin <br /> Valley, approximately fifteen (15) miles southwest of Stockton and <br /> two (2) miles west of Tracy. The elevation is approximately thirty <br /> feet (301 ) above sea level. Drainage is generally to the north <br /> toward the nearby (2 miles) Old River and adjacent slough areas. <br /> Physiographically, the ,site is located in the border area between <br /> older and younger alluvial fans (west and east, respectively) . <br /> Soils are classed .as Ambrose. Clay. Underlying sediments are <br /> described generally as relatively impermeable units of continental <br /> origin, ranging in age', from Miocene to Holocene. Sediment units <br /> which may be classed as "permeable" are reported to be lacking F <br /> above a depth of two - hundred feet (2001 ) . Recent (Holocene- i <br /> Pleistocene) uplift has deformed the area around the site' into a <br /> system of shallow upwarps and downwarps. The site itself is <br /> located on the gently north sloping nose of one of these upwarps. <br /> The immediately. underlying sediments in the area of drilling are <br /> uniformly clayey above a depth of thirty feet (301 ) (silty <br /> clay/clayey silt) . The groundwater table is shallow and is first <br /> I <br /> encountered in the drill holes at depths of from eight to ten feet <br /> (8 ' to 101 ) . Groundwater flow in the upper unconfined aquifer is <br /> generally to the northeast. <br /> t <br /> k <br /> Toxic Technology, Inc. <br /> i3 y <br />
