One boring was drilled to a depth of approximately 3 <br /> feet and the other was drilled to a depth of approximately 25 feet. The soil borings were used later <br /> 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 approximately 3 feet and 25 feet, as noted above, and were four inches in <br /> F diameter. <br /> } 5.3 Soil Lithology Observed <br /> e soil encountered in the boring is similar to the soils reported by the San Joaquin <br /> Generally, the g p <br /> County Soil Survey for the area (USDA, 1992). Table 3 presents the soil logs for the 25 foot deep <br /> soil borings. The soils were found to be comparable in the shallower boring on the parcel. <br /> F <br /> P <br /> a <br /> r <br /> 7 <br /> "A4 <br /> 01 <br /> I --- <br />
