KLEI NFELDER <br /> Review of the San Joaquin County Flood Control, District and Water Conservation map of Lines <br /> ' of Equal Elevation of groundwater, dated Spring 1994, indicates that the general direction of <br /> groundwater flow in the area of the site is to the east According to the map, the groundwater <br /> elevation is approximately -40 to -50 feet below mean sea level Comparison of that published <br /> ' groundwater elevation with the surface elevation of approximately 12 to 15 feet yields a depth to <br /> groundwater of 52 to 55 feet below grade Depth to groundwater is expected to be "mounded" <br /> ' beneath the Stockton Channel Therefore, depth to groundwater will be much less in fact, <br /> during a Phase lI Enviionmental Site Assessment (detailed in a separate report) depth to <br /> groundwater in borings HP-1, HP-2, and HP-3 (see Plate 2) was approximately 18 to 19 feet <br /> ' below grade Groundwater flow, depth and direction may be influenced by local pumping, <br /> rainfall, tidal fluctuation, or irrigation patterns Evaluation of such factor is beyond the scope of <br /> this assessment <br /> i <br /> I <br /> 1 <br /> 11-1111-101101711241 Page 5 of 16 <br /> ' © 1997 Kleinfekkr Inc.
