Note:The table descriptions do not necessarily reflect site-specific soil properties. 5.1 Soil Boring Locations Two soil borings were advanced on the Site, both borings were to a depth of three feet. The soil borings were used later for percolation test holes; the locations of the borings are indicated in Plate 1. 5.2 Soil Boring Dimensions The soil borings were three feet deep, as noted above, and were four inches in diameter. 5.3 Soil Lithology Observed 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 6 and 7 presents the soil logs for the three deep soil borings. 7 '.-44
