Ground water is anticipated to be <br /> encountered from 88 to 95 feet below ground surface at the Site; consequently, no <br /> modifications to standard septic systems should be required. <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 1847 Page 6 <br />
