' 5.3 Description of soil lithology as noted from test pit by appropriate professional using ' industry standard protocol. The soil in this area is classified as Rocklin Sandy Loam and San Joaquin Sandy Loam, as stated in the Soil Survey of San Joaquin County, as provided by the United States Department of Agriculture, Soil Conservation Service. ' 5.4 Discussion of soil lithology as related to future onsite septic uses: The soils classified as San Joaquin Sandy Loam in this area have permeability that is very slow. The soil classified as Rocklin San Loam in this area has a moderate permeability. The percolation rate was between 25 to 28 min/in.(See Appendix.) ' 6.0 PERCOLATION TEST INFORMATION SECTION 6.1 Site map showing the location, with concise and accurate dimensions of the percolation ' test holes on the parcel: See Appendix. 6.2 The minimum number of shallow and deep percolation tests were performed for each t parcel: Two shallow percolation test holes were prepared for this application. Two shallow percolation holes were previously tested June 2, 2011 under PA-10-279. (See Appendix.) The 2011 results are on two of the lots in this application. ' 6.3 Description of the date, time and protocol used to prepare the test hole, including depth and dimensions of hole, preparation of hole, and depth of water used to presoak(minimum ' 12 inches): The shallow test holes were excavated to a depth of 42 inches and 8 inches in diameter and backfilled with 2 inches of"pea gravel' in accordance with County Standards. The shallow holes were prepared by Mike Toy of Dillon and Murphy on June 27, 2018 at 7:30 a.m. On July 1, 2018 at 7:30 a.m. the 24 hours presoak period was started. The holes were filled with 12 inches of water over the gravel at this time. ' 6.4 Description of the date, time and condition of the test hole after the 24-hour soak period (hole still intact,hole dry,preparation of hole,and depth of water used to presoak(minimum 12 inches): On July 2, 2018 at 7:30 a.m. the two shallow test holes were dry. Six inches of water ' were added to the holes and the holes were deemed suitable to continue. The shallow test passed the minimum County requirements. ' 6.5 The test conformed to SJC Policy EH 02-02(correct depth,diameter,2" gravel,6" water refill,correct readings recorded). The percolation tests conformed to San Joaquin County Policy EHD 02-02. ' 6.6 Complete Percolation Test Form (including readings) was provided with REHS verification signature. The rate was correctly calculated using the last reading. See Appendix tfor Test Results Form.
