We recommend a Civil <br /> Engineer prepare a septic system design for Parcels 1 unless additional percolation testing on <br /> the Parcel indicates a satisfactory rate is achieved and approved by the EHD. <br /> - Septic System Construction should follow the San Joaquin County On-Site Wastewater Disposal <br /> Standards where applicable. <br /> 7.0 CONCLUSIONS <br /> fiIn summary, the parcel appears suitable for an engineered septic system. We recommend a <br /> Civil Engineer prepare a septic system design for Parcels 1 unless additional percolation testing <br /> on the Parcel indicates a satisfactory rate is achieved and approved by the EHD. <br /> _3 No ground water was encountered in any of the borings drilled on the property to a maximum <br /> of 25 feet. The on-site water well was tested for nitrate and DBCP. These results are still <br /> Fjpending and will be submitted to the county in a separate letter. <br /> F1 <br /> i <br /> k <br /> 902 Industrial Way•Lodi,CA 95240•209.367.3701 •Fax 209.369.4228 02007 Neil 0.Anderson&Associates, Inc <br />
