SOIL SUITABILITY STUDY, ACAMPO ESTATES <br /> Page No. 5 <br /> a deep pit percolation test. For approximate location of the percolation tests see the <br /> Location Map in the Appendix. <br /> The percolation tests were performed in 8 inch diameter test holes. For the shallow <br /> tests, a 3 inch diameter perforated pipe measuring device was placed in each test hole and <br /> backfilled with 3/4 inch gravel. For the deep pit tests, a 4 inch diameter perforated pipe <br /> was placed in each hole and backfilled with 3/4 inch gravel. All test holes were filled with <br /> water 24 hours prior-to running the tests. The last ten minutes or 30 minutes (whichever <br /> applied) of the test readings were witnessed by a San Joaquin County health official and the <br /> test data obtained is contained in the Appendix. A summary of the percolation test results <br /> is presented next: <br /> Diameter of Depth of <br /> Test No. Hole (inLL Hole (feet)- Percolation Rae min in <br /> BI-1 8 3.0 240 <br /> B 1-2 8 22.0 0.3 <br /> B2=1 8 3.0 320 <br /> B2-2 8 25.0 4.3 <br /> i <br /> I <br /> B3-1 8 3.0 480 <br /> B3-2 8 20.0 0.2 <br /> VII CONCLUSION <br /> Based on the results of the percolation tests, the soil profile, and the past <br /> performance of the existing septic systems on and around the surrounding property, it is our <br /> opinion that the subject property should be suitable for construction of typical on-site <br /> sewage disposal systems. Where cemented surface soils exist, these systems should consist <br /> of a septic tank, leach field, and dry wells. It is recommended that leach lines terminating <br /> in a dry well should be a minimum of 80 feet long. Proposed systems should be properly <br /> designed and installed according to current San Joaquin County criteria. <br /> 3 <br /> VE 40 l <br /> i <br />
