Presoaking of the holes commenced on June 2, 2005 and the tests were performed on June 3, <br /> 2005. The deep test holes were excavated to a depth of 24 feet and 21 feet respectively. The <br /> third deep test hole was excavated to 23 feet. All holes were backfilled with 2 inches "pea <br /> gravel". A 2 inch PVC pipe with perforations at the bottom was installed into the test hole and <br /> gravel was poured in the annular space. <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 /> May 5, 2005 the four shallow test holes were dry. Six inches of water was added to the holes <br /> and the holes were deemed suitable to continue. Two of the shallow tests passed the minimum <br /> County requirements. <br /> On June 3,2005, the first deep test holes were found to be intact and water was remaining in the <br /> holes. Four hour tests were performed. (See test results in appendix.) <br /> 6.5 The Test Conformed to San Joaquin County Policy EHD 02-02 (Correct Depth, <br /> diameter,2" gravel, 6" Water Refill, Correct Readings Recorded): The percolation tests <br /> conformed to 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 <br /> TEST HOLE PERCOLATION RATE <br /> 1 (Parcel 1) 15 MIN./IN. <br /> 2 (Parcel 4) 17.14 MINJIN. <br /> 3 (Parcel 2) 120 MINJIN.

Due <br /> to this classification and percolation rates, a standard septic system similar to those found on <br /> surrounding parcels would be recommended on Parcels 1 & 4, (Test holes 1 & 2). Engineered <br /> systems are recommended on Parcels 2 and 3 (Test holes 3 & 4). <br /> 6.8 Discussion of Percolation Rates in Relation to the Type, Size and Location of future <br /> leach fields at the site: Based on the results of the percolation rates and the soils profile, it is <br /> 4 <br /> c:\0466\Soi1 Report <br />
