LOGE 20-43: Ward-Crummey Percolation Test Page 3 <br /> September 5, 2020 <br /> The soils on the Site have demonstrated a satisfactory percolation rate for the use of a <br /> standard septic system in accordance with the requirements of the San Joaquin County <br /> Environmental Health Department. This percolation test is considered representative of soils <br /> within a 100-foot radius of the test location. <br /> Based on the percolation rate encountered between 1.0 and 5.0 min/in, the San Joaquin <br /> County Environmental Health Department will require a 20-foot separation from the bottom of <br /> the dispersal system to ground water. Ground water is anticipated to be encountered <br /> approximately 158 to 165 feet below ground surface at the Site; consequently, no <br /> modifications to a standard septic system should be required. <br /> Discussion of Septic System Sizing <br /> Septic system construction utilizing leach lines and seepage pits should follow the San Joaquin <br /> County On-Site Wastewater Treatment Systems Standards (2017) where applicable. The new <br /> septic system will require a permit from the San Joaquin County Environmental Health <br /> Department. <br /> We are pleased to be of service on this project. Please feel free to contact us should you have <br /> any questions. <br /> Sincerely, <br /> Live Oak GeoEnvironmental, Inc. <br /> /4 .Ile <br /> Abigail Racco, Project Manager o��SONAL <br /> ��� GF�I0 <br /> a� DAVID J.WELCH u <br /> * N0.2151 <br /> CERTIFIED <br /> ENGINEERING <br /> GEOLOGIST <br /> Davi Welch, Engineering Geologist TF <br /> OF CA <br /> CEG-2151, CHG-653, PGP-1049 IF� <br /> Attachments: Plate 1: Vicinity Map <br /> Plate 2: Site Map <br /> Percolation Test Permit <br /> Percolation Test Form <br /> CC: Michael Kith, REHS, Program Coordinator <br /> San Joaquin County Environmental Health Department <br />
