Shalloit, Test(s) <br />TEST HOLE <br />1 (Designated Remainder) <br />2 (Parcel 4) <br />3 (Parcel 3) <br />4 (Parcel 2) <br />5 (Parcel 1) <br />*See Results in Appendix. <br />PERCOLATION RATE <br />25 min./in. <br />25 min./in. <br />25 min./in. <br />50 min./in. <br />36 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 soil is classified as 220 — Redding Gravel loam, and <br />236 — San Joaquin County sandy loam and 237 — San Joaquin County Sandy loam. Due to this <br />classification and percolation rate, a standard septic system similar to the one found on the other <br />homesites in the project vicinity would be recommended on the proposed parcels. <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 soil 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 parcel, it is our opinion <br />that the installation of any new proposed septic system, if property installed, should not adversely <br />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 holes and performed the percolation tests. It was assumed that the test holes <br />and 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.
