or) Blossom Road Subdivision Page 5 of 9 <br /> Our Project Number: LG5080511 <br /> April 30, 2008 <br /> 1/5.5.1 Soil Boring Locations <br /> A total of eight (8) soil borings were advanced on the site, one (1) groundwater boring to a <br /> depth of nine (9) feet and seven (7) soil borings to a depth of approximately 3.5 feet. The soil <br /> borings were used later for percolation test holes; the locations of the borings are indicated in <br /> Plate 1. <br /> /5.5.2 Soil Boring Dimensions <br /> The soil borings were approximately 3.5 in depth, as noted above, and were four (4) inches in <br /> diameter. <br /> 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 the soil log for the soil <br /> borings. Conditions were comparable in all of the holes. <br /> Table 2 <br /> Soil Boring Log <br /> DeMOM <br /> pth•Interval (ft) SoilaType Unified Soil Classification <br /> M <br /> 0 - 1.5 Dark brown silty clay CL <br /> 1.5 - 3.5 Light brown sandy silt SM <br /> Greyish brown silty clay CL <br /> J5.4 Discussion of Soil Lithology <br /> A visual inspection of the soils from on-site drilling indicates potential for percolation because of <br /> the nature of the soils. A percolation test is the best method to determine the suitability of the <br /> soils for a septic disposal area. Please see the next section for percolation test results. <br /> Generally speaking, coarser-grained soils have much greater potential for percolation than fine- <br /> grained or cemented soils. <br /> �46.0 PERCOLATION TEST INFORMATION <br /> 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 /> Number of Percolation Tests <br /> One (1) percolation test was conducted on each parcel, for a total of seven (7) percolation tests <br /> conducted on the property. <br /> 902 industrial Way•Lodi,CA 95240•209.367.3701 •Fax 209.369.4228 02008 Neil 0..4nderson& 4ssociales,Inc <br />
