Note: A satisfactory percolation rate for a"shallow' test is less than or equal to 60 minutes per inch. <br /> A satisfactory percolation rate for a"deep" test is less than or equal to 30 minutes per inch. <br /> r (/ 6.7 Discussion of Percolation Test Results <br /> L The soils within the sewage disposal areas of Parcels 1 and 2 demonstrated a satisfactory percolation <br /> rate in accordance with the requirements of the EHD. The soils of these parcels appear to be <br /> suitable for a septic system utilizing shallow leach lines and seepage pits. <br /> L //6.8 Discussion of Septic System Sizing <br /> Septic System Construction should follow the San Joaquin County On-Site Wastewater Disposal <br /> 6a Standards where applicable. Refer to the attached Nitrate Loading Study for a complete discussion <br /> of recommendations for the project. <br /> 7.0 CONCLUSIONS <br /> ` 7.1 Signatures <br /> The signatures of the environmental professionals involved in the preparation of this report can be <br /> found at the front of this package. <br /> 9 <br /> L '404 <br /> L <br />
