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 8 inches in diameter. The holes 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 project site contains four different soil types. The first soil type is Jahant loam with 0 to 2 percent slopes. The second soil type is San Joaquin loam with slopes of 2 to 8 percent. Third is the San Joaquin complex, with slopes of 0 to 1 percent. Lastly, the San Joaquin-Urban land with slopes of 0 to 2 percent. All of the soils are composed of top layers of loam followed by indurated material. (See Appendix.) 5.4 Discussion of soil lithology as related to future onsite septic uses: The soils on the project site have good percolation rate for the first foot,then percolation starts to slow down significantly. All the test holes percolated at 50 min/in or faster. (See Appendix.) 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: The shallow percolation test holes were prepared on the proposed location for a septic tank. 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 Mike Toy of Dillon and Murphy on March 1, 2020 at 7:30 a.m. On March 1, 2020 at 7:30 a.m. the 24 hours presoak period was started. The holes were filled with 12 inches of water over the gravel 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,preparation of hole,and depth of water used to presoak(minimum 12 inches): On March 2, 2020 at 7:30 a.m. the shallow test holes were dry. Six inches of water were added to the holes and the holes were deemed suitable to continue. The shallow test passed the minimum County requirements. 6.5 The test conformed to SJC Policy EH 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. 3
