See <br /> Appendix. <br /> 5.2 Description of soil profile pit including depth and dimensions. The shallow test holes <br /> were prepared per County Standards. The holes were excavated to depths of 22.5 and 25 inches <br /> and 8 inches in diameter. They were backfilled with 2 inches of"pea gravel". <br /> 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 Cogna Loam and San Joaquin <br /> Sandy Loam as stated in the Soil Survey of San Joaquin County, as provided by the United <br /> States Department of Agriculture, Soil Conservation Service. <br /> 5.4 Discussion of soil lithology as related to future onsite septic uses: The Cogna <br /> Loam and San Joaquin Sandy Loam have permeability that is moderate. <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 were performed for each <br /> parcel: Four shallow percolation test holes were prepared on-site. One shallow percolation test <br /> hole was prepared 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 depths of 22.5 and 25 inches <br /> and 8 inches in diameter and backfilled with 2 inches of"pea gravel" in accordance with County <br /> Standards.
