Discussion of Percolation Test Results <br />The soils within the proposed sewage disposal area of the Site have demonstrated a <br />satisfactory percolation rate for the use of a septic system in accordance with the <br />requirements of the San Joaquin County Environmental Health Department. This <br />percolation test is considered representative of soils within a 100-foot radius of the test <br />location. <br />Because of the percolation rate between 1.0 and 5.0 min/in encountered in the test <br />hole, the San Joaquin County Environmental Health Department will require a 20-foot <br />separation from the bottom of the dispersal system to ground water, or other system <br />modification. Based on the predicted depth to water of 135 to 165 feet, no modifications <br />to standard systems should be necessary to meet this requirement. <br />Discussion of Septic System Sizing <br />Septic system construction utilizing leach lines and seepage pits should follow the San <br />Joaquin County On-Site Wastewater Treatment Systems Standards (2017) where <br />applicable. <br />LOGE 2114 Page 7
