In this area, the soils are classified as Redding Gravelly Loam and <br /> San Joaquin Sandy Loam. Due to this classification, percolation rate, and depth to ground water, <br /> a standard septic system similar to those found on the surrounding parcels would be recommended. <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 rates and the soils profiles, it is <br /> Dillon& Murphy's opinion that the subject parcels are suited for a typical on-site sewage disposal <br /> system. These systems should be properly designed and installed according to the current San <br /> Joaquin County criteria for standard septic systems. <br /> Based on the depth to groundwater in the area, and the size of the proposed parcel,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 we <br /> excavated our test hole and performed the percolation test. It was assumed that the test hole and <br /> percolation 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.
