For specific boring depths at the time of testing please refer to table 11. The soil borings <br /> were used later for percolation test holes;the locations of the borings are indicated in Plate 1. <br /> 5.2 Soil Boring Dimensions <br /> The soil borings were about-three.and a half feet deep, as noted above, and were about four inches <br /> in diarrieter. <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). Table's-4 through 8 present the soil logs for the <br /> three foot deep soil borings. <br /> 4 <br /> Fj <br /> Ft <br />
