Based <br /> ' on the borings drilled for the geotechnical investigation in October 2015, the subsurface soils <br /> below a depth of 10 feet consisted of silty sand to a depth of about 15 feet, underlain by sandy <br /> lean clay to a depth of about 40 feet. <br /> The Soil Survey of San Joaquin County, California published by the U.S. Department of <br /> ' Agriculture, Soil Conservation Service (1992) refers to the near-surface soil within the area of the <br /> proposed new septic system as belonging to the Veritas Fine Sandy Loam soil series (Map <br /> ' Symbol 266). This soil is described as having "moderate" percolation characteristics for septic <br /> tank absorption. Other near-surface soils identified within the parcel belong to the Honcut Sandy <br /> Loam soil series (Map Symbol 175) and the Tinnin Loamy Coarse Sand soil series (Map Symbol <br /> 255).
