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 Acampo Sandy Loam, Bruella <br /> Sandy Loam and Tokay Fine Sand Loam, as stated in the Soil Survey of San Joaquin County, as <br /> provided by the United States Department of Agriculture, Soil Conservation Service. <br /> 5.4 Discussion of soil lithology as related to future onsite septic uses: The soils <br /> classified as Acampo Sandy Loam and Tokay Fine in this area have permeability that is <br /> moderately rapid. The soil classified as Bruella Sandy Loam in this area was a permeability that <br /> is moderately slow. The percolation rate was between 16.66 and 25 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 April 26, 2019 at 8:00 a.m. On <br /> May 7, 2019 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 May 8,2019 at 7:30 a.m.the two shallow test holes were dry. Six inches of water <br /> was added to the holes and the holes were deemed suitable to continue. The shallow tests passed <br /> 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 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. See Appendix <br /> for Test Results Form. <br /> Shallow Test(s) <br /> TEST HOLE PERCOLATION RATE <br /> 1 (Parcel 1) 16.66 Min/In <br /> 2 (Parcel 2) 25 Min/In <br /> 3 <br />
