6.6 Complete Percolation Test Form (including readings) was provided with REHS <br />verification signature. The rate was correctly calculated using the last reading. See Appendix <br />for test results form. <br />Shallow Test <br />TEST HOLE <br />Parcel I <br />PERCOLATION RATE <br />50 min./in. <br />6.7 Discussion of any potential problems predicted and/or the need for an engineered or <br />alternative septic system. In this area, the soils are classified as Tokay Fine Sandy Loam and <br />Tujunga Loamy Sand. Due to this classification, a standard septic system similar to the one found <br />on the homesites in the area would be recommended on the proposed parcels. They would be sized <br />based on their intended use. <br />6.8 Discussion of percolation rates in relation to the type, size and location of future leach <br />fields needed at the site. Based on the results of the percolation rate and the soils profile, it is <br />Dillon & Murphy's opinion that the subject proposed parcel is suited for a typical on-site sewage <br />disposal system. The systems should be properly designed and installed according to the current <br />San Joaquin County criteria for standard septic systems. <br />Based on the depth to groundwater in the area, and the size of the proposed parcels, it is our opinion <br />on that the installation of any new proposed septic system, if property installed, should not <br />adversely affect the quality of groundwater in the area. <br />7.0 CONCLUSION SECTION <br />The conclusions of this report are based on the information provided regarding the proposed <br />development, the use of the subject property, and the site conditions as they existed at the time of <br />the Basecamp Environmental, Inc. initial study. It was assumed that the test hole and percolation <br />test results are representative of the subsurface conditions in the general area. <br />Our services were performed, our findings obtained, and our conclusions proposed in accordance <br />with generally accepted engineering principles and practices.
