4WLIVE OAK GEO ENVIRONMENTAL, INC. <br /> 407 W. Oak St., Lodi, CA 95240 E- (209)369-0375 ❖ logelodi.com <br /> April 13, 2016 <br /> Project Number: 1607 <br /> John Meek <br /> Reclamation District 2023 <br /> 1440 Arundel Ct. <br /> Lodi, CA 95242 <br /> Regarding: Septic System Recommendations <br /> Venice Island Ferry Tender's Residence <br /> 15501 W. Eight Mile Rd., Stockton, CA <br /> Mr. Meek: <br /> Per your request, Live Oak GeoEnvi ron mental (Live Oak) has evaluated the site <br /> conditions and provided septic system recommendations for a new Ferry Tender's <br /> residence to be placed on Venice Island at 15501 West Eight Mile Road, Stockton <br /> (Plate 1). We understand that the residence will be a two-bedroom modular home to be <br /> occupied by a three-person family. <br /> Rodney Estrada, Program Coordinator for Land Use at the San Joaquin County <br /> Environmental Health Department (SJCEHD), has indicated that a previous <br /> investigation completed by Neil 0. Anderson & Associates in 1996 found a rapid <br /> percolation rate in the soil near the proposed septic disposal area. Because of this test <br /> result and the shallow ground water in the area, the SJCEHD has recommended that an <br /> engineered septic system be designed for the project. <br /> You informed us that a pad had been constructed in preparation for the septic system <br /> installation. Because the site conditions had changed since the previous investigation, <br /> Live Oak performed four percolation tests to assess the current percolation rates of <br /> various soil layers in the proposed disposal area. <br /> Field Investigation <br /> On April 7, 2016, Live Oak excavated four soil borings with a four-inch hand auger in <br /> and near the proposed septic disposal area for the purpose of conducting percolation <br /> tests. The holes were advanced to 2.45, 2.50, 4.50, and 5.75 ft below ground surface; <br /> the locations of the borings are indicated on Plate 2. <br /> At the same time, Live Oak advanced a boring to first ground water near the percolation <br /> test area. Ground water was encountered at 13 ft below ground surface from the septic <br /> disposal pad. <br /> Environmental Engineering Geology o Geophysics <br />
