GROUND WATER <br /> From the San Joaquin County Flood Control and Water <br /> Conservation District Study we find that the ground <br /> water depth is approximately 80 feet and that the <br /> gradient falls northerly at approximately 25 feet per <br /> mile. See Exhibits 2 and 3 . <br /> The ground water was tested by F.G.L. Environmental. <br /> The results of those tests are listed in Exhibits 5 and <br /> 6. <br /> SOILS AND PERCOLATION TEST <br /> Per the "Soils of San Joaquin County" , as published by <br /> the University of California, the soil is Hanford Sandy <br /> Loam. <br /> On August 4 , 1993 , we ran percolation tests on Parcels <br /> 1 and 2 . It was found that the percolation rates were <br /> 5 and 6/min/inch respectively. See Exhibit 4 . <br /> In all cases the test holes were 6" diameter by 3 feet <br /> deep. The tests were run under permit and inspection <br /> by the San Joaquin County Health Department. <br /> CONCLUSION <br /> The area is suitable for septic systems . It is <br /> recommended that 8 ,000 S .F. be reserved on Parcels 1 <br /> and 2 . <br /> Based upon the percolation test and interviews, it is <br /> my professional opinion that a septic system will not <br /> adversely effect the first water aquifer. <br /> LIMITATIONS <br /> The conclusions of this report are based on the <br /> information provided regarding the existing and <br /> proposed development, and on the site conditions as <br /> they existed at the time we performed the percolation <br /> test. It was assumed that the test hole and <br /> percolation test results are representative of an <br /> average of the subsurface conditions in the general <br /> area. <br />
