Soil Profile and Geologic Information <br /> The Site is mapped on the Geologic Map of Califomia, San Jose sheet (Rogers, 1966). <br /> It is depicted within a map unit of recent Great Valley fan deposits (Plate 7). <br /> The surface and near surface soils located at the Site are reported by the USDA Web <br /> Soil Survey to be composed of Delhi loamy sand, 0 to 2 percent slopes, and Honcut <br /> sandy loam, 0 to 2 percent slopes (Plate 8) (USDA, 2009). The table below presents <br /> some selected properties of these soils: <br /> Table 1.

The <br /> borings were four inches in diameter and were excavated by hand auger. Their depths <br /> were 3.24, 3.23, and 3.12 feet below ground surface. The locations of the borings are <br /> indicated on Plate 2. <br /> The soil in the borings was similar to that described by the Soil Survey; sandy silt was <br /> observed from the surface to the maximum depth of the borings (3.24 feet). The log for <br /> the soil borings is presented in Plate 9. <br /> Discussion of Soil Lithology <br /> Based on the soils observed in the boring, there appears to be moderate potential for <br /> percolation. Sandy soils generally have a much greater potential for percolation than <br /> fine-grained or cemented soils. However, a percolation test is the only accepted <br /> LOGE 1110 Page 4 <br />
