The soil borings were used later for percolation test holes; the locations of the 1 borings are indicated in Plate 1. 5.2 Soil Boring Dimensions The soil borings were approximately three and a half feet, as noted above, and were four inches in diameter. ! 5.3 Soil Lithology Observed F1Generally, the soils encountered in the borings were similar to the soils reported by the San Joaquin County Soil Survey for the area (USDA, 1992). Table 4 presents a soil log for the three and a half foot soil borings. Table 4. Soil Boring Log. Depth Interval(ft) Soil Type Unified Soil Classification 0-3.5 Brown sandy silt SM F1a } F 6 4
