Hazelton Ave. <br /> Stockton, CA 95205 <br /> Regarding: Addendum to Soil Suitability Study <br /> Van Elderen Property Qe�> <br /> 19238 E. Highway 120, Ripon, CA <br /> PA-1100208 <br /> Original report completed February 4, 2011 <br /> Dear Mr. Tasiopoulos, <br /> When Mr. Van Elderen originally retained our office to prepare a Soil Suitability Study, the <br /> above property was to be divided into one parcel and a designated remainder. However, since <br /> the completion of our Soil Suitability Study, a second numbered parcel has been added to the <br /> project. As a result, we have completed a new percolation test for the project. <br /> One shallow percolation test was conducted on the Site. Percolation test procedures <br /> conformed to San Joaquin County Environmental Health Department policy. <br /> Soil Boring <br /> On December 4, 2012, Live Oak excavated one shallow soil boring on the Site for the purpose <br /> of conducting a percolation test. The boring was four inches in diameter, 3.35 feet deep, and <br /> was excavated by hand auger. The soil in the boring was observed to be silty, fine sand to the <br /> maximum depth of the boring. The boring location is indicated on the attached plate. <br /> Preparation and Presaturation of Percolation Test Hole <br /> After the boring was advanced by hand auger, the test hole was completed for the percolation <br /> test. Approximately one inch of pea gravel was placed in the bottom of the open soil boring, <br /> followed by a 1.5-inch diameter PVC pipe with perforations on the bottom. Pea gravel was <br /> then used to backfill a few inches of the annular space. <br /> Live Oak presaturated the percolation test hole approximately 24 hours prior to the percolation <br /> test. The hole was filled with water to a height of 12 inches above the bottom of the boring for <br /> the presaturation. On the day of testing, the shallow hole was found to be intact and dry. <br /> Environmental Engineering Geology . Geophysics <br />
