The soil borings were used later for percolation test holes; the locations of the borings are <br /> indicated in Plate 1. <br /> ,/5.5.2 Soil Boring Dimensions <br /> The soil borings were approximately 3.5 feet, as noted above, and were four (4) inches in <br /> diameter. <br /> m ;/5.5.3 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). The table below presents a representative soil <br /> log for the four (4) soil borings. Conditions were comparable in the all of the soil borings. <br /> Table 2 <br /> Soil Boring Log <br /> Depth Interval (ft) Soil Type Unified Soil Classification <br /> 0 - 8.5 Medium brown, silty clay CL <br /> 5.4 Discussion of Soil Lithology <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, coarser-grained soils have much greater potential for percolation <br /> than fine-grained or cemented soils. <br /> 6.0 PERCOLATION TEST INFORMATION <br /> ,8.1 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 /> ' 6.2 Number of Percolation Tests <br /> One (1) percolation test was conducted on each parcel, for a total of four (4) shallow <br /> percolation tests conducted on the property. <br /> .*44 <br /> 902 Industrial Way•Lodi,CA 95240•209.367.3701 •Fax 209.369.4228 02008 Nei(O.Anderson&Associates.Inc <br />
