(minutes/inch) (see notes) <br /> below ground surface, <br /> Incomplete test <br /> Gravels and Cobbles, <br /> P-4 (shallow) 2.3 * 35.7 4-hr Auger refusal at 2.3 feet <br /> 11-15-07 below ground surface, <br /> Incomplete test <br /> *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 /> Minimum Test Depth 3.0' <br /> 6.7 Discussion of Percolation Test Results <br /> The soils within the sewage disposal areas of Parcel 1 and 2 have demonstrated a satisfactory <br /> percolation rate in accordance with the requirements of the EHD for the use of a standard <br /> septic system. Parcels 3 and 4 appear suitable for an engineered septic system. <br /> 6.8 Discussion of Septic System Sizing <br /> For Parcels 1 and 2, Septic System Construction should follow the San Joaquin County On-Site <br /> Wastewater Disposal Standards where applicable. Parcels 3 and 4 appear suitable for use with <br /> an engineered septic system. Our office has been contracted by the client to design the system <br /> for both parcels 3 and 4. <br /> 7.0 CONCLUSIONS <br /> In summary, percolation rates that meet the minimum EHD standards were achieved in the <br /> proposed septic disposal areas of proposed Parcels 1 and 2. These parcels appear suitable for <br /> the use of a standard septic system. <br /> The proposed Parcels 3 and 4 appear suitable for an engineered septic system. We recommend <br /> a Civil Engineer prepare a septic system design for Parcels 3 and 4 unless additional percolation <br /> testing on the Parcel indicates a satisfactory rate is achieved and approved by the EHD. Our <br /> office has been contracted by the client to prepare engineered septic system designs for Parcels <br /> 3 and 4. They will follow this report shortly. <br /> No ground water was encountered in any of the borings drilled on the property. The depth to <br /> ground water was approximately 195 to 230 feet below the ground surface for the period of Fall <br /> 2003 and Spring 2004 based on county groundwater maps. No well water sample was taken. <br /> r. 902 Industrial Way•Lodi,CA 95240•209.367.3701 •Fax 209.369.4228 ©2007 Neil O.Anderson&Associates,Inc <br />
