i <br /> February 3, 2005 <br /> n NOA Project Number: E040116A <br /> 5.1 Soil Boring Locations <br /> Five soil borings were advanced by hand auger on the Site; one on each parcel. All of the borings <br /> were to a depth of three feet. The-soil borings were used later for percolation test holes; the <br /> locations of the borings are indicated u a e . <br /> 5.2 Soil Boring Dimensions <br /> The soil borings were three feet deep and were three inches in diameter. <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). Tables 4-8 present the soil logs for the 3-foot deep <br /> soil borings. <br /> F <br /> Table 4. <br /> Soil Boring Log for P-1. <br /> Depth Interval (ft) Soil Type.
