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 Hollenback Silty Clay as stated in the <br /> Soil Survey of San Joaquin County, California 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 Hollenbeck Silty Clay <br /> permeability is slow. Percolation rates were 16-42 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 was Performed for Each 60 L, <br /> Parcel: Three shallow percolation test holes were prepared on the proposed parcels. <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 /> (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 of Dillon& Murphy. On <br /> November 11, 2014 at 7:30 a.m., the 24 hour presoak period was started. The holes were filled <br /> with 12 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 <br /> Period (Hole Still Intact,Hole Dry, Depth to Water Remaining in Hole, Etc.): On <br /> November 12, 2014 at 7:30 a.m. the test holes were dry. Six inches of water was added to the <br /> holes and the holes were deemed suitable to continue. The shallow tests passed the minimum <br /> County requirements. <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 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: <br /> (See Appendix for Test Result Form.) <br /> Shallow Test Results <br /> TEST HOLE PERCOLATION RATE <br /> _ 1 (Parcel 3) 17 Min./In. <br /> 2 (Parcel 2) 42 Min./In. <br /> 3 (Parcel 1) 16 Min./In. <br /> *See Results in Appendix. <br /> 3 <br /> YADMD0C\2014\1435\SSS Nov 2014.doc <br />
