' 5.2 Description of soil profile pit including depth and dimensions. The shallow test holes were prepared per County Standards. The holes were excavated to a depth of 42 inches and 10 inches in diameter. They were backfilled with 2 inches of"pea gravel." ' 5.3 Description of soil lithology as noted from test pit by appropriate professional using industry standard protocol. The soil in this area is classified as Cogna Fine Sandy Loam, ' Cogna Loam, Columbia Fine Sandy Loam, Pardee Cobbly Loam, Pentz Sandy Loam, Pentz Cobbly Sandy Loam, Pentz-Bellota Complex, Peters Clay, pits, gravel and Xerofluvents as stated in the Soil Survey of San Joaquin County, and provided by the United States Department of Agriculture, Soil Conservation Service. 5.4 Discussion of soil lithology as related to future onsite septic uses: The soils classified as ' Pardee Cobbly Loam and Peters Clay in this area have a permeability that is slow. The soils classified as Cogna Fine Sandy Loam and Cogna Loam in this area have a moderate permeability. The soils classified as Columbia Fine Sandy Loam, Pentz Sandy Loam, Pentz Cobbly Sandy Loam, ' and Pentz-Bellota complex in this area have a permeability that is moderately rapid. The soil classified as Pentz Sandy Loam in this area have a permeability that is rapid. The soil classified as Xerofluvents in this area have a permeability that is slow to rapid. The passing percolation rates ' were between 18 to 28 min/in (See Appendix). These rates are suitable for on-site septic systems. 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 were performed for each parcel: Fifteen shallow percolation test holes were prepared. Deep tests were not required. ' 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 10 inches in diameter and backfilled with 2 inches of "pea gravel" in accordance with County Standards. The shallow holes were prepared on December 11, 2015. On December 14, 2015 at 6:30 a.m. the 24 hour presoak period was started. On December 15, 2015 the test holes were pre-soaked for Parcels 10 through 14. The holes were filled with 12 inches of water over the ' gravel at this time. On December 16, 2015 at 6:30 a.m. the 24 hour presoak period was started for Parcels 1 through 9, and 15. ' 6.4 Description of the date, time and condition of the test hole after the 24-hour soak period (hole still intact, hole dry, preparation of hole, and depth of water used to presoak (minimum 12 inches): On December 15, 2015 at 6:30 a.m. the shallow test holes for Parcels 10 ' through 14 were dry. Six inches of water was added to the holes and the holes were deemed suitable to continue. These test holes were observed by Mike Toy of Dillon & Murphy. On December 17, 2015 at 7:30 a.m. the shallow test holes for Parcels 1 through 9 and Parcel 15 were dry. Six inches of water was added to the holes and the holes were deemed suitable to continue. These test holes were observed by Mike Toy of Dillon& Murphy. The shallow test holes passed the County minimum requirements for percolation rate. t3
