Note:The table descriptions do not necessarily reflect site-specific soil properties. 11/5.1 Soil Boring Locations LFoto soil borings were advanced on the Site. Two boring were drilled to a depth of 25 feet,and two borings to a depth of three and a half feet. The soil borings were used later for percolation test Lholes;the locations of the borings are indicated in Plate 1. /5.2 Soil Boring Dimensions The soil borings were 25 or three and a half feet deep, as noted above,and were four inches in diameter. L ✓5.3 Soil Lithology Observed L Generally, the soil encountered in the boring is similar to the soils reported by the San Joaquin County Soil Survey for the area (USDA, 1992). Table 4 presents a representative soil log for a 25-foot deep soil boring. Conditions were comparable in both borings. L L L ' L
