Satisfactory percolation rate. <br /> ` Parcel 2 <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 /> 6.7 Discussion of Percolation Test Results <br /> The soils within the sewage disposal areas of the proposed Parcels 1 and 2 have demonstrated a t G ?J <br /> satisfactory percolation rate in accordance with the requirements of the EHD. The soils of these <br /> parcels appear to be suitable for a septic system utilizing deep leach lines and seepage pits. -STL) <br /> 6.8 Discussion of Septic System Sizing <br /> Septic system construction should follow the San Joaquin County On-Site Wastewater Disposal <br /> Standards where applicable. <br /> 7.0 CONCLUSIONS <br /> In summary, satisfactory percolation rates of the soil were achieved in the proposed septic disposal <br /> areas of both parcels. The parcels appear suitable for a standard septic system. We recommend that <br /> the design and installation of the septic systems follow the requirements established by the EHD. <br /> No ground water was encountered in any of the borings drilled on the property, and the depth to <br /> ground water is approximately 80-100 feet below the ground surface for the period of Fall 1998 and <br /> Spring 1999. No water sample was collected because no wells exist on the Site. <br /> 8.0 LIMITATIONS <br /> The conclusions of this report are based on the information provided regarding the existing and <br /> proposed development, the use of the subject property, and the site conditions as they existed at the <br /> time we excavated our test holes and performed the percolation tests. It was assumed that the test <br /> holes and percolation test results are representative of the subsurface conditions in the general area. <br /> 8 <br />
