(See Appendix). <br /> 6.0 PERCOLATION TEST RWORMATION 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 <br /> Parcel: Five 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 /> (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 July 17, 2011 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 /> July 18, 2011 at 7:30 a.m. the five 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 Massed the <br /> minimum 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 Farm (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 <br /> TEST HOLE PERCOLATION RATE <br /> 1 (Parcel 1) 31 Min./In. <br /> 2(Parcel 2) 42 Min./lu. <br /> 3(Parcel 3 50 Min./In. <br /> 4(Parcel 4) 36 Nun./In. <br /> DR(Designated Remainder) 31 Min./In. <br /> *See results in Appendix. <br /> 3 <br /> Y:IDMD00120%10141S0IL SUITABILITY STUDY 00211-doe <br />
