The soil borings were used later for percolation test holes; the locations of the <br /> borings are indicated in Plate 1. <br /> 1.5.2 Soil Boring Dimensions <br /> The soil borings were approximately 3.15 feet and 5.5 feet in depth, as noted above, and were <br /> four (4) inches in diameter. <br /> 1.5.3 Soil Lithologv 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). The table below presents the soil log for the soil <br /> borings. Conditions were comparable in the shallower hole. <br /> Table 4. <br /> Soil Boring Log. <br /> Depth Interval (ft) Soil Type Unified Soil Classification <br /> 0-5.5 Medium brown, silty clay CL <br /> 1.5.4 Discussion of Soil Lithologv <br /> A visual inspection of the soils from on-site drilling indicates some potential for percolation <br /> because of the nature of the soils. A percolation test,is the best method to determine the <br /> suitability of the soils for a septic disposal area. Please see the next section for percolation test <br /> results. Generally speaking, sandy soils have much greater potential for percolation than fine- <br /> grained or cemented soils. <br /> 1.6 Percolation Test Information <br /> 1.6.1 Percolation Test Locations <br /> A site map indicating the locations of the percolation test holes is included as Plate 1 in the <br /> appendix of this report. <br /> 1.6.2 Number of Percolation Tests <br /> Two (2) percolation tests were conducted on the property. <br /> '.'44 <br /> 902 Industrial Way• Lodi,CA 95240• 209.367.3701 •Fax 209.369.4228 02008 Neil O.Anderson&Associates.Inc <br />
