F <br /> f <br /> Ff Y--5.4 Discussion of soil lithology as related to future onsite septic uses: The soils <br /> classified in this area have a permeability that ranges from moderate to very slow. The percolation <br /> rates were between 35.7 to 50.0 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 /> F /6.2 The Minimum Number of Shallow and Deep Percolation Tests was Performed for Each <br /> Parcel: Four shallow percolation test holes were prepared, one on each 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 /> F. (Minimum 12 Inches): The shallow test holes were excavated to a depth of 42 inches and <br /> 12 inches in diameter and backfilled with 2 inches of"pea gravel" in accordance with County <br /> Standards. The shallow holes were prepared by Mike Toy on June 25, 2010 at 7:00 a.m. On <br /> F June 27, 2010 at 7:30 a.m. the 24 hour presoak period was started. The holes were filled with <br /> 12 inches of water over the gravel at this time. <br /> ,, t1-6.4 Description of the Date,Time and Condition of the Test Hole After the 24-Hour Soak <br /> Period (Hole Still Intact, Hole Dry,Depth to Water Remaining in Hole,Etc.): On June 28, 2010 <br /> at 7:30 a.m. the four shallow test holes were dry. Six inches of water was added to the holes and <br /> the holes were deemed suitable to continue. The shallow tests passed the minimum County <br /> /6.5 <br /> requirements. <br /> FThe Test Conformed to San Joaquin County Policy EHD 02-02 (Correct Depth, diameter, <br /> 2" gravel, 6" Water Refill, Correct Readings Recorded): The percolation tests conformed to <br /> San Joaquin County Policy EHD 02-02. <br /> Flit ,/6.6 Complete Percolation Test Form (Includin Readings)Was Provided With REHS <br /> Verification Signature.
