i <br /> Shallow <br /> a <br /> TEST HOLE PERCOLATION RATE <br /> k 1 (Parcel 1) 15 MIN./IN. <br /> i <br /> 2 (Parcel 1) 15 MIN./IN. <br /> F *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 Vignolo Silty Clay Loam. <br /> Due to this classification and percolation rates, a standard septic system similar to the one found <br /> on near the home would be recommended on the rest of the property. <br /> 6.8 Discussion of Percolation Rates in Relation to the Type, Size and Location of future <br /> Fj 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 parcel is suited for a typical on-site sewage disposal <br /> systems. These systems should be properly designed and installed according to the current San <br /> F Joaquin County criteria for standard septic systems. L <br /> Based on the depth to groundwater in the area, and the size of the proposed parcels, it is our <br /> F 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 /> F 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 /> l Our services were performed, our findings obtained, and our conclusions proposed in accordance <br /> with generally accepted engineering principles and practices.
