i <br /> kn KLEINFELDER <br /> of the four hour period is recorded and used to calculate the percolation rate in minutes per inch. <br /> The estimated percolation rates are summarized below. A copy of our field percolation test <br /> results signed by a representative from SJC/EHD is attached. <br /> Test Number Depth, feet Percolation Rate min./inch <br /> Parcel l 7.5 11.9 <br /> Parcel 2 6.5 2.6 <br /> Parcel 3 7.0 10.4 <br /> Parcel 4 6.5 10.4 <br /> CONCLUSIONS <br /> The results of our percolation tests indicate that a conventional septic tank/leach trench sewage <br /> disposal system with seepage pits should adequately serve the proposed development. The <br /> seepage pits should extend to the sandy soils underlying the site that were encountered at depths <br /> ranging from about 6.5 to 7.5 feet below site grade. <br /> LIMITATIONS <br /> The conclusions of this report are based on the information provided regarding the existing and <br /> proposed development and on the site conditions. It was assumed that the percolation test results <br /> are representative of the subsurface conditions in the general area. As previously mentioned, <br /> nitrate and DBCP testing was previously performed by others. <br /> This completes the scope of work requested. Our work was performed in general accordance <br /> with the standard of care that exists in San Joaquin County.
