DODDS ROAD <br /> ESCALON, CALIFORNIA <br /> Dear Mr. TeVelde: <br /> As requested, on August 31, 1999, personnel of our firm drilled and set-up three percolation test <br /> holes on the subject project site. The approximate locations at which the percolation tests were <br /> performed are indicated on Plate A-1 included with this report. Our services were provided as <br /> outlined in our proposal dated August 27, 1999 and with your written authorization of August <br /> 27, 1999. <br /> P The percolation test holes were drilled with a truck-mounted drill rig equipped with 6-inch <br /> diameter, continuous-flight augers. The test holes were drilled to depths of approximately 3, 11, <br /> and 15 feet below existing ground surface. A log of the soils encountered in the 15-foot deep test <br /> ' hole is included as Plate A-4. The soils were classified according to the Unified Soil <br /> Classification System which is described on Plate A-2; a key to the Log of Boring is presented <br /> on Plate A-3. A small amount of gravel was placed in the bottom of each test hole, the test holes <br /> were cased with slotted PVC pipe, and the test holes were partially filled with relatively-clean <br /> water and left to soak overnight. <br /> On September 1, 1999, a representative of our firm returned to the site to perform the percolation <br /> tests per San Joaquin County guidelines. The tests were performed for four hours, and the last <br /> thirty minutes of each test were used to calculate the percolation rates indicated in the following <br /> table, The County approved percolation field test sheets are included with this report. <br /> PERCOLATION TEST RESULTS <br /> ...'.'Test NumberDepth (Feet) Percolation Bate(miiinutes per inch) <br /> P-1 31/z 120 <br /> P-2 15 10 <br /> P-3 11 20 <br /> 20-4370-0LG01/2019L811 September 3, 1999 <br /> © 1999 Kleinfelder,Inc.
