Soil Boring Log, Parcel 1 <br /> Depth Interval (ft) Soil Type Unified Soil Classification <br /> 1-10 Brown silty clay with some <br /> k ravel CL <br /> F10.17 Brown silty cemented clay <br /> with some ravel CL <br /> FF 17-25 Brown silty clay with some CL <br /> { ravel <br /> Within the boring, an inch of "pea gravel" was placed in the bottom of the hole to stabilize the <br /> side wall from caving and prevent erosion while filling the boring. A 2-inch diameter PVC pipe <br /> with open ends and slots was placed in the hole. About six inches of pea gravel was placed in <br /> the annular space around the pipe. The hole was pre-soaked 24 hours prior to the test with 12 <br /> F inches of water above the bottom of the hole. <br /> During the percolation test, the fall of six inches of water was measured above the top of gravel <br /> F during the four (4) hour test period. Measurements were made every 30 minutes for a four (4) <br /> hour period. The last half hour of the test was inspected by Michael Escotto, Inspector EHD. <br /> l ' Table 2 <br /> Summary of Percolation Tests <br /> Test No., Date Percolation <br /> Percolation Comments <br /> Tested Test Depth Test Duration <br /> feet Rate (min/in) (see notes) <br /> Parcel 1 23.30 12.5 4 Hours Satisfactory <br /> Percolation <br /> Rate <br /> Parcel 2 21.15 250 4 Hours Failing percolation <br /> F` <br /> } Rate <br /> Parcel 3 24.05 4.10 4 Hours Satisfactory <br /> Percolation Rate <br /> Parcel 4 24.15 83.3 4 Hours Failing percolation <br /> iI Rate <br /> Note: A satisfactory percolation rate for a"shallow"test is less than or equal to 60 minutes per inch. <br /> A satisfactory percolation rate for a"deep"test is less than or equal to 30 minutes per inch. <br /> Either a shallow or a deep percolation test needs to meet the minimum acceptable percolation <br /> rate established by the EHD for a standard test. The soils within the sewage disposal areas of <br /> Parcels 1 and 3 on the subject property have demonstrated a satisfactory percolation rate in <br /> accordance with the requirements of the EHD for the use of a standard septic system. <br /> ( I <br /> 1 h <br /> P <br /> 902 Industrial Way•Lodi,CA 95240-209.367.3701 •Fax 209.369.4228 ©2008 Neil 0.Anderson&Associates,Inc <br />
