The borings were drilled to a depth of three feet. The <br /> soil borings were used later for percolation test holes; the locations of the boxings are indicated in <br /> Plat <br /> 5.2 Soil Boring Dimensions <br /> The soil borings were-three feet deep, as noted above, and were three inches in diameter. <br /> 5.3 Soil Lithology Observed <br /> Generally, the soil encountered in the boring is similar to the soils reported by the San Joaquin <br /> County Soil Survey for the area (USDA, 1992). Tables 4 and 5 present the soil logs for the three <br /> foot deep soil borings. <br /> Table 4. <br /> Soil_Bori �Log for P-1. <br /> Depth Interval (ft) Soil Type Unified Soil Classification <br /> 0-2 Dark brown,moist,clayey silt MIL <br /> F <br /> 2_3 Brown,moist,sandy silt ML <br /> k-d 6 <br /> Fj <br />
