The findings of the report indicate the septic system will need <br /> to be engineered due to the size limitations of the property, along with modifications to the <br /> system to help mitigate potential nitrate buildup from on site use. <br /> A Sept system design and layou�was completed for the site/based on the number of <br /> employees, soil conditions, percolation test rates and the requirements of the San Joaquin <br /> Environmental Health Department. Please see the SS/NLS for further details regarding the <br /> 33 West Mathews Road property site conditions. <br /> Septic System <br /> A Stan rd septic system for three (3) employees per day will reuire a primary disposal field of <br /> 774 squ re feet. A 100 percent replacement fieldivill quire 774 square feet. In order to <br /> reduce the disposal field sizes, Mr. Rodney Estrada`,or the n Joaquin County Environmental /' <br /> `Jiea Department (EHD) indicated that a "double 'to tripl• thickness" engineered filter bed <br /> would be acceptable and would reduce the tro om ea ware footage by,,half or a third. <br /> Therefore, the primary area has been reduced M 338 square feet and the 100 percent area to <br /> 338 square feet by irl reasing the thickness of t e ed from 12 to 42 in�hes. In order to <br /> help mitigate nitrate buildup, four (4) inches of co t hould be placed at the bottom of the <br /> filter bed. Please see the attached work sheet for st dard San Joaquin County EHD septic <br /> system calculation. \ <br /> ANGELS CAMP • LODI • MODESTO • RENO • SACRAMENTO • WALNUT CREEK <br /> L 0 D I 902 Industrial Way • Lodi,CA 95240 • 209.367.3701 FAX 209-369.4228 • w .noandersonxom <br />
