NW November 23, 2004 <br /> NOA Project Number: E04140A <br /> The surface and near surface soils located at the site are reported to be the Tokay fine sandy loam <br /> (no. 256) (Plate 9). The San Joaquin Soil Survey describes the soil as a very deep,well drained, <br /> nearly level soil on low fan terraces. It formed in alluvium derived from granitic rock sources. <br /> Permeability is moderately rapid in the Tokay soil. Table 1 presents selected properties of the Tokay <br /> fine sandy loam. <br /> Table 1. <br /> —San Joaquin County Soil Survey— <br /> Selected Soil Properties of On-Site Soils. <br /> Soil Name and Map Depth(in) Unified Soil Salinity Soil Septic tank <br /> Symbol Classification mmhos/c Reaction absorption <br /> m pH fields Limits <br /> r. <br /> Tokay fine sandy 0-19:Fine sandy loam.

The location of the percolation test can <br /> be found on Plate 3. <br /> 5.2 Soil Boring Dimensions <br /> �— The soil boring was 3.0 feet deep and was four (4) inches in diameter. <br /> 5.3 Soil Lithology Observed <br /> Generally, the soil encountered in the boring is similar to the soils indicated in the San Joaquin <br /> County Soil Survey (USDA, 1992).
