5.4 Discussion of soil lithology as related to future onsite septic uses: The soils <br /> ' classified as Tokay Fine Sandy Loam in this area have permeability that is moderately rapid. <br /> The percolation rate was between 17 to 19 min/in. (See Appendix.) <br /> ' 6.0 PERCOLATION TEST INFORMATION SECTION <br /> 6.1 Site map showing the location, with concise and accurate dimensions of the percolation <br /> ' test holes on the parcel: See Appendix. <br /> 6.2 The minimum number of shallow and deep percolation tests were performed for each <br /> ' parcel: Two shallow percolation test holes were prepared for this application. <br /> 6.3 Description of the date, time and protocol used to prepare the test hole, including depth <br /> ' and dimensions of hole, preparation of hole, and depth of water used to presoak(minimum <br /> 12 inches): The shallow test holes were excavated to a depth of 42 inches and 12 inches in <br /> diameter and backfilled with 2 inches of"pea gravel" in accordance with County Standards. The <br /> ' shallow holes were prepared by Mike Toy of Dillon & Murphy on September 12, 2018 at 6:30 <br /> a.m. On September 12,2018 at 7:30 a.m.the 24 hours presoak period was started. The holes were <br /> filled with 12 inches of water over the gravel at this time. <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 September 13, 2018 at 7:30 a.m. the two shallow test holes were dry. Six inches <br /> of water were added to the holes and three holes were deemed suitable to continue. The shallow <br /> test passed the minimum County requirements. <br /> 1 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 /> 6.6 Complete Percolation Test Form (including readings) was provided with REHS <br /> ' verification signature. The rate was correctly calculated using the last reading.
