The laboratory analytical results are attached as Appendix 5 of this report. <br /> Soil Profile and Geologic Information <br /> The Site is mapped on the Preliminary geologic map of showing Quaternary deposits of <br /> the Lodi Quadrangle, California (Marchand and Atwater, 1979). It is depicted within two <br /> map units of the Modesto Formation upper member, described as "arkosic alluvium <br /> forming Mokelumne River alluvial fan; chiefly sand, becoming finer-grained toward fan <br /> toe, probably glacial outwash" and "arkosic alluvium forming low dunes on Mokelumne <br /> 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 Soil Survey of <br /> San Joaquin County, California (USDA, 1992) to be composed of Tokay fine sandy <br /> loam and Tujunga loamy sand (Plate 8). The table below presents some selected <br /> properties of these soils: <br /> Table 1.

See description of the map unit for <br /> composition and behavior characteristics of the map unit. <br /> Soil Borings <br /> On November 11, 2014, Live Oak excavated shallow soil borings on Parcels 1 and 2 of <br /> the Site for the purpose of conducting percolation tests. The borings were four inches in l' <br /> diameter, 3.30 and 3.40 feet deep, and were excavated by hand auger (Table 2). The / <br /> locations of the boring are indicated on Plate 9. r 1) <br /> The soil in the borings was similar to that described by the Soil Survey. In boring P1, <br /> silty sand was encountered to the full depth of the hole. In boring P2, sand with silt was 5 g, <br /> encountered to the full depth of the hole. The logs for the soil borings are presented on <br /> Plates 10 and 11. <br /> LOGE 1422 Page 5 <br />
