5.3 Description of soil lithology as noted from test pit by appropriate professional using industry <br /> standard protocol. The soil in this area is classified as Rocklin Sandy Loam, Cometa Sandy Loam and <br /> San Joaquin Sandy Loam as stated in the Soil Survey of San Joaquin County, as provided by the United <br /> r States Department of Agriculture, Soil Conservation Service. <br /> 5.4 Discussion of soil lithology as related to future onsite septic uses: The soils classified as <br /> San Joaquin Sandy Loam, and Cometa Sandy Loam in this area have a permeability that is very slow. <br /> The soil classified as Rocklin Sandy Loam in this area has a moderate permeability. The passing <br /> percolation rates were between 17 to 50 min/in. (See Appendix). <br /> 6.0 PERCOLATION TEST INFORMATION SECTION <br /> 6.1 Site map showing the of cation,with concise and accurate dimensions of the percolation test <br /> holes on the parcel: See Appendix. <br /> 6.2 The jniaim m number of shallow and deep percolation tests were performed for each <br /> parceVSixteen shallow percolation test holes were prepared. <br /> 6.3 Description of the date, time and protocol used to prepare the test hole, including <br /> depth and dimensions of hole, preparation of hole, and depth of water used to presoak <br /> (minimum 12 inches): The shallow test holes were excavated to a depth of 42 inches and 10 inches <br /> in diameter and backfilled with 2 inches of"pea gravel" in accordance with County Standards. The <br /> shallow holes were prepared on May 15, 2013. On May 16, 2013 at 6:30 a.m. the 24 hour presoak <br /> period was started. On May 17, 2013 the test holes that were pre-soaked were for Parcels 9 through 16. <br /> ` The holes were filled with 12 inches of water over the ground at this time. On May 19, 2013 at 6:30 <br /> a.m. the 24 hour presoak period was started for Parcels 1 through 8. <br /> 6.4 Description of the date, time and condition of the test hole after the 24-hour soak period <br /> (hole still intact, hole dry, preparation of hole, and depth of water used to presoak(minimum <br /> 12 inches): On May 17, 2013 at 6:30 a.m. the shallow test holes for Parcels 11, 14, 15, and 16 were dry. <br /> Six inches of water was added to the holes and the holes were deemed suitable to continue. These test <br /> holes were observed by Mike Toy of Dillon& Murphy. Also on May 17, 2013 at 7:30 a.m. the shallow <br /> test holes for Parcels 9, 10, 12, and 13 were dry. Six inches of water was added to the holes and the / <br /> holes were deemed suitable to continue. These test holes were observed by Shaun Mackey of <br /> Dillon& Murphy. On May 20, 2013 at 6:30 a.m. the shallow test holes for Parcels 3, 4, 7, and 8 were <br /> dry. Six inches of water was added to the holes and the holes were deemed suitable to continue. These <br /> test holes were observed by Mike Toy of Dillon& Murphy. On May 20, 2013 at 7:30 a.m. the shallow <br /> test holes for Parcels 1, 2, 5, and 6 were dry. Six inches of water was added to the holes and deemed <br /> suitable to continue. These holes were observed by Shaun Mackey of Dillon& Murphy. The shallow <br /> test holes passed the County minimum requirements. <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 tests conformed to San Joaquin County Policy <br /> EHD 02-02. <br /> 3 <br />
