On-Site Wells No wells are currently located on the Site. No well permits were identified for the Site from among the files of the San Joaquin County Environmental Health Department. Water Sample No water sample was collected as part of this investigation. Soil Profile and Geologic Information The Site is depicted on the Geologic map of the San Francisco-San Jose quadrangle, California (Wagner et al., 1991). The Site is depicted within a map unit of Holocene alluvial fan deposits (Plate 8). The surface and near surface soils located at the Site are reported by the USDA Web Soil Survey to be composed of Capay clay (Plate 9) (USDA, 2019). The table below presents some selected properties of this soil: Table 1.

See description of the map unit for composition and behavior characteristics of the map unit. Soil Borings On February 18, 2020, Live Oak excavated a shallow soil boring near the proposed septic disposal area of the Site for the purpose of conducting a percolation test. The boring was four inches in diameter, 3.46 feet deep, and was excavated by hand auger (Table 2). The location of the boring is indicated on Plate 10. The soil in the boring was similar to that described by the Soil Survey. Clay was encountered to 1.5 feet below ground surface, followed by silty clay to 3.2 feet, followed by silty clay with calcium carbonate to the full depth of the hole. The soil log is presented on Plate 11. LOGE 20-08 Page 4
