✓ 5.4 Discussion of soil lithology as related to future onsite septic uses: The Acampo and Devries Sandy Loam has moderate rapid permeability thus; percolation rates were 20.83 to 25 min/in. (See Appendix). i 6.0 PERCOLATION TEST INFORMATION SECTION ✓ 6.1 Site Map Showing the location,with concise and accurate dimensions of the percolation test holes on the parcel: See Appendix. 6.2 The Minimum Number of Shallow and Deep Percolation Tests was Performed for Each Parcel: Two shallow percolation test holes were prepared, one on each proposed parcel. 6.3 Description of the Date,Time and Protocol Used to Prepare the Test Hole, Including Depth and Dimensions of Hole, Preparation of Hole, and Depth of Water Used to Presoak(Minimum 12 Inches): The shallow test holes were excavated to a depth of 42 inches and ` 8 inches in diameter and backfilled with 2 inches of"pea gravel' in accordance with County Standards. The shallow holes were prepared by David Lind February 13, 2008 at 7:00 a.m. On February 13, 2008 at 7:30 a.m. the 24 hour presoak period was started. The holes were filled with 12 inches of water over the gravel and at this time. 6.4 Description of the Date, Time and Condition of the Test Hole After the 24-Hour Soak Period (Hole Still Intact, Hole Dry, Depth to Water Remaining in Hole, Etc.): On February 14, 2008 at 7:30 a.m. the two shallow test holes were dry. Six inches of water was added to the holes and the holes were deemed suitable to continue. The shallow tests passed the minimum County requirements. % 6.5 The Test Conformed to San Joaquin County Policy EHD 02-02 (Correct Depth,diameter, 2" gravel, 6" Water Refill, Correct Readings Recorded): The percolation tests conformed to San Joaquin County Policy EHD 02-02. 6.6 Complete Percolation Test Form (Including Readings) Was Provided With REHS Verification Signature. The Rate Was Correctly Calculated Using the Last Reading: See Appendix for Test Result Form. Shallow TEST HOLE PERCOLATION RATE 1 (Parcel 1) 20.83 MINJIN. 2 (Parcel 2) 25.00 MINJIN. *See Results in Appendix. 6.7 Discussion of Any Potential Problems Predicted and/Or the Need for An Engineered or Alternative Septic System: In this area, the soils are classified as Acampo and Devries Sandy Loam. Due to this classification and percolation rates, a standard septic system similar to the ones found on the other homesites would be recommended on Parcels 1 and 2. 3 c:\0799\Soil Suitability Report 032008
