Leadstone Drive, Acampo <br /> APN: 005-360-02, SR0085988 <br /> The San Joaquin County Environmental Health Department (EHD) has reviewed the Soil Suitability/Nitrate <br /> Loading (SSNL) Study, dated October 26, 2022 and has the following comments for your consideration. <br /> The SSNL Study was prepared to determine the suitability of the above noted parcel for onsite wastewater <br /> treatment system (OWTS) usage and the potential long-term impact of nitrate to groundwater from the <br /> proposed three (3) bedroom single family residence and one (1) bedroom guest house. <br /> Based on the information provided, the EHD can make the following findings: <br /> 1. Based on the information provided the EHD finds that the SSNL Study supports the suitability for <br /> standard OWTS usage for the proposed development pursuant to San Joaquin County Ordinance <br /> Code Title 9, Section 9-1105.2(d). <br /> 2. Percolation test conducted on October 20, 2022 yielded a percolation rate of 2.03 minutes/inch. At <br /> this rate, a 20' soil separation shall be required between bottom of dispersal field and groundwater <br /> pursuant to San Joaquin County Onsite Wastewater Treatment Standard table 1.10.2. Per SSNL <br /> Study, groundwater on site is between 85' to 95' feet below surface grade. <br /> 3. The OWTS and its 100% replacement areas shall meet all required minimum setbacks stated in San <br /> Joaquin County (OWTS) Standard and Well Standard. <br /> If you have any questions please contact Naseem Ahmed, Senior Registered Environmental Health <br /> Specialist, at nahmed@sjgov.org or (209) 616-3018. <br /> ,,-7z Z-- Z- <br /> IR.r <br /> Steven Shih, REHS <br /> Program Coordinator <br /> c: Sierra Vista Construction-20282 N.
