5.4 Discussion of soil lithology as related to future onsite septic uses: The Delhi Loamy Sand <br /> and Veritas Fine Sandy Loam have moderately rapid to rapid permeability thus; percolation rates <br /> were 13 to 16 min/in. (Se ppendi <br /> 6.0 PERCOLATION TEST INFORMATION SECTION <br /> 6.1 Site Map g Showin 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 was Performed for Each <br /> Parcel: Two shallow percolation test holes were prepared, one on each proposed parcel. <br /> L1 <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 /> k ; (Minimum 12 Inches): The shallow test holes were excavated to a depth of 42 inches and <br /> 8 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 at 7:30 a.m. On October 11, 2010 at <br /> 7:30 a.m. the 24 hour presoak period was started. The holes were filled with 12 inches <br /> 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 <br /> Period (Hole Still Intact, Hole Dry, Depth to Water Remaining in Hole,Etc.): On <br /> October 11, 2010 at 7:30 a.m. the two shallow test holes were dry. Six inches of water was <br /> added to the holes and the holes were deemed suitable to continue. The shallow tests passed theme <br /> minimum County-requArements. <br /> 6.5 The 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 ELID_02-02.. <br /> G , <br /> 6.6 Complete Percolation Test Form (Including Readings) Was Provided With REHS <br /> Verification Signature.
