L <br /> LNovember 9, 2005 <br /> NOA Project Number: E05118B <br /> L5.1 Soil Boring Locations <br /> Eight soil borings were drilled to a depth of approximately three and a half feet on the Site. The soil <br /> Lborings were later used as percolation test holes, see Plate I for the boring locations. <br /> 5.2 Soil Boring Dimensions <br /> LThe soil borings were approximately three and a half feet deep, as noted above,and were four <br /> inches in diameter. <br /> L 5.3 Soil Lithology Observed <br /> L Generally,the soil encountered in the borings is similar to the soil reported by the San Joaquin <br /> County Soil Survey for the area (USDA, 1992). Tables 3 presents the soil log for the borings on the <br /> subject property. <br /> Table 3. <br /> Soil Boring Log for P-C. <br /> Depth Interval(ft) Soil Type Unified Soil Classification <br /> 0-3 Dark Brown,moist,sandy clay CL <br /> it 5.4 Discussion of Soil Lithology <br /> A visual inspection of the shallow soils from on-site drilling indicates some potential for satisfactory <br /> L percolation. A percolation test is the best method to determine the suitability of the soils for a <br /> septic disposal area. Please see the next section for percolation test results. Generally speaking, <br /> Lcoarser grained soils have much greater potential for percolation than fine-grained soils. <br /> L 6.0 PERCOLATION TEST INFORMATION <br /> L <br /> 6.1 Percolation Test Locations <br /> LA site map indicating the locations of the percolation test hole is included as Plate 1 of this report. <br /> L6.2 Number of Percolation Tests <br /> One shallow percolation test was conducted on each parcel of the Site for a total of eight shallow <br /> percolation tests. <br /> L <br /> L <br />
