Shallow <br /> TEST HOLE PERCOLATION RATE <br /> — 1 (Parcel 1) 28 MIN./IN. <br /> 2 (Designated Remainder) 2$ MIN./IN. <br /> *See Results in Appendix. <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 Stockton Silty Clay Loam. <br /> Due to this classification and percolation rates, a standard septic system would be suitable for the <br /> parcels. <br /> 6.8 Discussion of Percolation Rates in Relation to the Type, Size and Location of future <br /> leach fields at the site: Based on the results of the percolation rates and the soils profile, it is <br /> Dillon&Murphy's opinion that the subject proposed parcels 1 and "designated remainder" are <br /> suited for a typical on-site sewage disposal systems. These systems should be properly designed <br /> and installed according to the current 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 <br /> opinion that the installation of any new proposed septic system, if properly 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 <br /> we excavated our test holes and performed the percolation tests. It was assumed that the test <br /> holes and percolation tests results are representative of the subsurface conditions in the general <br /> area. <br /> Our services were performed, our findings obtained, and our conclusions proposed in accordance <br /> ` with generally accepted engineering principles and practices.
