CONCLUSIONS AND RECOMMENDATIONS <br /> A satisfactory percolation rate was obtained for each of the seven(7)parcels. Two of the <br /> percolation tests achieved a passing percolation rate at a depth betwe 6 inches while the <br /> �- remainder required the test be placed adjacent to a deeper permeable sandy layer to achieve a <br /> passing percolation rate. Although an achievable percolation rate may be found at some <br /> locations on the site as shown by two of the seven(7) percolation tests, the use of the seepage <br /> pits is recommended to ensure good performance of the septic system. <br /> No shallow ground water was encountered during the on-site drilling. The estimated <br /> depth to ground water at the site based on San Joaquin County Flood Control and Water <br /> Conservation District ground water depth and elevation maps for Spring 1998 and for Fall 1998 <br /> ` is between 70 to 73 feet flowing generally northwest. <br /> We believe the soils of the seven(7)parcels are suitable for use with a septic system. <br /> Since the size of each parcel is about 10 acres+- and the depth to ground water is fairly deep, <br /> we believe the use of the septic system will not negatively impact ground water quality. We <br /> recommend the design of the septic system follow the San Joaquin County"Sewage Standards" <br /> L <br /> r <br /> 'pEEtO <br /> N <br /> Z <br /> 0 <br />
