L <br /> LJune 1,2006 <br /> NOA Project Number: E05179A <br /> LTest No., Percolation Percolation Rate Test Comment <br /> Date Tested Test Depth(ft) (minutes/inch) Duration (see notes) <br /> L Parcel D,Deep 24,31 5.56 4 hour Satisfactory Percolation Rate <br /> 5-12-06 <br /> Parcel D,Shallow 3.07 No movement 4 hour Failing Percolation Rate <br /> 2-27-06 <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 /> L6.7 Discussion of Percolation Test Results <br /> L The soils within the sewage disposal areas of the parcels have demonstrated a satisfactory / <br /> percolation rate in accordance with the requirements of the EHD for the use of a standard septic <br /> Lsystem. <br /> ` 6.8 Discussion of Septic System Sizing <br /> L Septic System Construction should follow the San Joaquin County On-Site WastewaterDirposal <br /> Standards where applicable. <br /> L 7.0 CONCLUSIONS <br /> L In summary,percolation rates that meet the minimum EHD standards were achieved in the <br /> proposed septic disposal areas of the site. The parcels appear suitable for the use of a standard septic <br /> system. <br /> LNo ground water was encountered in any of the borings drilled on the property. No well water <br /> sample was taken because no wells exist on the property. Groundwater depth lies between 60 and 80 <br /> Lfeet below ground surface. <br /> 8.0 LIMITATIONS <br /> L <br /> The conclusions of this report are based on the information provided regarding the existing and <br /> I proposed development, the use of the subject property, and the site conditions as they existed at the <br /> L, 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 /> L <br /> L g <br /> L ".44 <br /> L <br />
