New Moose Lodge Soil Suitability Study Page 5 of 9 <br /> Our Project Number: E07175A <br /> November 5, 2007 <br /> 5.0 SOIL PROFILE AND GEOLOGIC INFORMATION <br /> The Site is depicted on the USGS Preliminary Geologic Map Showing Quaternary Deposits of the <br /> Lodi Quadrangle, California (Marchand and Atwater, 1979) as within two units of the <br /> Quaternary Modesto Formation upper member. The map units are described as consisting of <br /> "arkosic alluvium forming Mokelumne River alluvial fan; chiefly sand, becoming finer-grained <br /> toward fan toe; probably glacial outwash," and "arkosic sand forming low dunes on the <br /> Mokelumne River fan and in the Delta; probably eolian, although not well sorted" (Plate 7). <br /> The surface and near surface soils located at the Site are reported by the San Joaquin County <br /> Soil Survey to be composed of Tokay fine sandy loam, 0-2 % slopes (Plate 8) (USDA, 1992). <br /> Table 3 presents some selected properties of these soils: <br /> Table 3. <br /> San Joaquin County Soil Survey <br /> Selected Soil Properties of On-Site Soils. <br /> Soil Name Depth Unified Soil Classification Salinity Soil Perme- Septic tank <br /> and Map (in) (mmhos/cm) Reaction ability absorption <br /> Symbol pH (in/hr) fields <br /> Tokay fine 0-19: Fine sandy loam; SM <2 6.1-7.8 2.0-6.0 Slight <br /> sandy loam, 19-45 Fine sandy loam, sandy loam; <2 6.1-7.8 2.0-6.0 <br /> 0-2 % SM <br /> slopes, 256. 45-60 Fine sandy loam, sandy loam, <2 6.1-8.4 2.0-6.0 <br /> coarse sandy loam; SM <br /> 5.1 Soil Boring Locations <br /> A total of two soil borings were advanced on the Site, one boring to a depth of 3.30 feet and <br /> one boring to a depth of 5.80 feet. The soil borings were used later for percolation test holes; <br /> the locations of the borings are indicated in Plate 1. <br /> 5.2 Soil Boring Dimensions <br /> The soil borings were 3.30 and 5.80 feet in depth, as noted above, and were four inches in <br /> diameter. <br /> 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 <br /> 5.80-foot soil boring. Conditions were comparable in the shallower hole. <br /> ",44 <br /> 902 Industrial Way•Lodi,CA 95240•209.367.3701 •Fax 209.369.4228 ©2007 Neil O.Anderson&Associates,Inc <br />
