5.3 Description of soil lithology as noted from test pit by appropriate professional using <br />industry standard protocol. The Soil in this area is classified as Sandy Loam as stated in the <br />Soil Survey of San Joaquin County, as provided by the United States Department of Agriculture, <br />Soil Conservation Service. <br />5.4 Discussion of soil lithology as related to future onsite septic uses: The Sandy <br />Loam has a permeability that is moderately well drained. <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 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 6 inches <br />in diameter and backfilled with 2 inches of "pea gravel" in accordance with County Standards. <br />The shallow hole was prepared by Tristan Hartung of Dillon & Murphy on July 21, 2021 at 7:30 <br />a.m. On July 22, 2021 at 7:30 a.m., the 24 hour presoak period was started. The hole was filled <br />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 July 23, 2021 at 7:30 a.m., the shallow test hole was dry. Six inches of water was <br />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.
