' 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 San Joaquin Sandy Loam as <br /> stated 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 soils <br /> classified as San Joaquin Sandy Loam in this area have permeability that is very slow. The <br /> percolation rate was between 42 to 50 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 Dan Cardoza,the owner on July 31, 2018 at 7:30 a.m. On <br /> July 31, 2018 at 7:30 a.m. the 24 hours presoak period was started. The holes were filled with 12 <br /> ' 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 August 2, 2018 at 7:30 a.m. the two shallow test holes were dry. Six inches of <br /> water were added to the holes and the holes were deemed suitable to continue. The shallow test <br /> ' passed the 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 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.
