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: Hicksville Loam, Montpellier-Cometa Complex, Rocklin Sandy Loam and a small portion of Yellowlark 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 underlying soils have a permeability that is moderate. The moderately high permeability of the soil makes it suitable for on-site wastewater treatment systems. 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 parcel: One deep percolation test hole was prepared on each of the proposed parcels. 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 1.2 inches): The shallow test holes were excavated to a depth of 42 inches and 12 inches in diameter and backfilled with 2 inches of "pea gravel" in accordance with County Standards. The shallow holes were prepared by Bradley Handel of Dillon and Murphy on June 15, 2022, at 7:30 a.m. On July 5, 2022 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 1.2 inches): On July 6, 2022 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 RE:HS verification signature. The rate was correctly calculated using the last reading. See Appendix for Test Results Form. Shallow Test(s) TEST :BOLE I (Parcel l) 2 (Parcel 2) *See Results in Appendix.
