3 <br /> 6.5 The test conformed to SJC Policy EH 02-02(correct depth,diameter,2" gravel,6"water <br /> refill,correct readings recorded). The percolation test conformed to San Joaquin County Policy <br /> EHD 02-02. <br /> 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 /> PERCOLATION <br /> TEST HOLE DATE RATE <br /> 1 (Parcel 1) 10/29/2019 27.8 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 soil is classified as Bruella Sandy loam, hard <br /> substratum, 0 to 2 percent slopes. Due to this classification and percolation rate, a standard septic <br /> system similar to the ones found on neighboring properties would be recommended on the <br /> 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 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 /> 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.
