Dog Kennel Building-Soil Suitability Study Page 9 of 13 <br /> Our Project Number: NA157000G <br /> June 2, 2015 <br /> 5.0 SOIL PROFILE AND GEOLOGIC INFORMATION <br /> The site is depicted on the California Geological Survey Geologic Date Map No. 2, as within the <br /> alluvium of the Quaternary (Q) Formation 2. These Pleistocene-Holocene soils consist primarily <br /> of alluvium, lake, playa and terrace deposits (Plate 5). <br /> The surface and near surface soils located at the site are reported by the United States <br /> Department of Agriculture (USDA) Natural Resource Conservation Service (Plate 6) to be <br /> composed of Capay clay 0 to 2 percent slopes and 2 to 5 percent slopes3, consisting of <br /> moderately well-drained clay alluvium derived from mixed rock sources including sandstone and <br /> shale. <br /> 5.1 Soil Boring Locations <br /> A total of one (1) soil boring was advanced on the site to perform a percolation test. The location <br /> of the boring is depicted in Plate 2. <br /> 5.2 Soil Boring Dimensions <br /> The soil boring was advanced to 3.42 feet bgs and four (4) inches in diameter. <br /> 5.3 Soil Lithology Observed <br /> The table below presents the soil log for the soil boring. <br /> Table 1. <br /> Soil Boring Log. <br /> Depth Interval (ft) Soil Type Unified Soil Classification <br /> 0-3.42 Silty clay— moist, brownT_ <br /> CL <br /> 5.4 Discussion of Soil Lithology <br /> A visual inspection of the soils from on-site drilling indicates favorable conditions in septic <br /> disposal areas. Generally speaking, coarse-grained soil has a greater potential for percolation <br /> than fine-grained or cemented soil. <br /> z State of California Department of Conservation. http•//www quake ca goy/gmaps/images/GMC Explanation pdf <br /> y 3 USDA. http://websoitsurvey.sc.egov.usda.gov/App/WebSoitSurvey.asi)x <br /> ©2015 Neil O.Anderson&Associates,Inc.A Terracon Company <br />
