5.3 Description of soil lfthology as noted from test pit by appropriate professional using <br /> industry standard protocol: The soil in this area is classified as San Joaquin Sandy Loam <br /> as stated in the Soil Survey of San Joaquin County, California as provided by the United States <br /> Department of Agriculture, Soil Conservation Service. <br /> 5.4 Discussion of soil lithology as related to future onsite septic uses: The San Joaquin Sandy <br /> Loam has slow permeability. (See Appendix). <br /> 6.0 PERCOLATION TEST INFORMATION SECTION <br /> 6.1 Site Map Showing the to on,wit concise and accurate dimensions of the percolation <br /> test holes on the parcel: See Appendi . <br /> 6.2 The Minimum Number o ow and Deep Percolation Tests was Performed for Each <br /> Parcel: Five deep percolation test holes were prepared by staff of Neil O. Anderson &Associates, <br /> 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): (See report prepared by Neil O. Anderson &Associates.) <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.): (See report <br /> prepared by Neil O. Anderson&Associates.) <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 Com lete Percolation Test Form (Including Readings)Was Provided With REHS <br /> Veri c on 1 ature. The Rate Was Correctly Calculated Using the Last Reading: <br /> LSee Appendi or Test Result Form. <br /> Deep Test Results <br /> L See report prepared by Neil. O. Anderson & Associate m Appendix. <br /> 6.7 Discussion of Any Potential Problems Predicted and/Or the Need for An Engineered or <br /> Alternative Septic System: In this area, the soils are classified as San Joaquin Sandy Loam. <br /> (See report prepared by Neil O. Anderson&Associates.) <br /> 6.8 Discussion of Percolation Rates in Relation to the Type, Size and Location of future <br /> leach fields at the site: (See report prepared by Neil O. Anderson & Associates.), <br /> Based on the depth to groundwater in the area, and the size of the proposed parcels, it is our <br /> opinion that the installation of any new proposed septic system, if properly installed, should not <br /> adversely affect the quality of groundwater in the area. -- <br /> 3 <br /> .. <br /> c:\OSOSSoiI Suitability Report 092009 <br />
