0 <br /> Generally the surface soils consisted of clay. As shallow percolation tests <br /> proved adequate for conventional septic systems, no further soil exploration was <br /> necessary. <br /> The two percolation tests were performed in holes varying from 9 inch to 10 <br /> inch diameter by 36 inch deep backfilled with 3" of gravel. All holes were filled with <br /> water 24 hours prior to running the test. The test holes for Parcel 1 and the <br /> remainder parcel were performed under a 4 hour test. The last half hour of the tests <br /> readings were witnessed by a County Health Official and the test data obtained is <br /> enclosed in the Appendix. <br /> Parcel Number Percolation Rate <br /> 1 1 inch/hr. <br /> Remainder 1.5 inch/hr. <br /> VII. CONCLUSION <br /> Based on the results of the percolation tests and the soil profile, it is Dillon & <br /> Murphy's opinion that the homesite and remainder parcel resulting from the proposed <br /> parcel split of the subject property is suited for the construction of a typical on site <br /> sewage disposal system. The proposed system, however, should be properly <br /> designed and installed according to current San Joaquin County criteria. <br /> It should be noted that the location of each of the percolation tests was chosen as the <br /> most likely location for a disposal field. If the actual location of a proposed disposal <br /> field varies significantly from the test locations, the test data should not be considered <br /> accurate of other locations. <br /> Based on the depth to ground water in the area, and the size of the proposed <br /> parcels, it is our opinion that the installation of the proposed septic systems, if properly <br /> installed, should not adversely affect the quality of the ground water in the area. <br /> VII. LIMITATIONS <br /> The conclusions of this report are based on the information provided regarding <br /> the proposed development, the use of the subject property, and the site as they <br /> existed at the time we excavated out test hole and performed the percolation tests. It <br /> was assumed that the test hole and percolation test results are representative of the <br /> subsurface conditions in the general area. <br /> 2 <br />
