The Soil in this area is classified as Finrod clay loam and as stated <br />in the Soil Survey of San Joaquin County, as provided by the United States Department of <br />Agriculture, Soil Conservation Service. <br />5.4 Discussion of soil lithology as related to future onsite septic uses: The <br />Finrod clay loam has a permeability that is slow. <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: One shallow percolation test hole was prepared on the proposed parcel. <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 hole was 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. <br />The shallow hole was prepared by Mike Toy of Dillon & Murphy on June 12, 2020 at 7:30 a.m. <br />On June 16, 2020 at 7:30 a.m., the 24 hours presoak period was started. The hole was filled with <br />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 June 17, 2020 at 7:30 a.m., the 1 shallow test hole was dry. Six inches of water <br />was added to the hole and the hole was deemed suitable to continue. The shallow test passed the <br />minimum County 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 test 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.
