i 1 } 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 Columbia Fine Sandy„ Loam, and Redding Gravelly Loam as stated in the Soil Survey of San Joaquin County, / as provided by the United States Department of Agriculture, Soil Conservation Service. 5.4 Discussion of Soil Lithology as Related to Future On-site Septic Uses: The soils classified as Redding Gra��11 - oam ' this area have a permeability that is very slow. The soil classified as Columbia Fine Sandy Loam in this area have a moderately rapid permeability. The percolation rate was between 10 to 42 min/in (See Appendix).

F, 6.3 De rip ion 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 hole was prepared by Mike Toy of Dillon& Murphy on November 18, 2010, Fat 7:00 a.m. On November 18, 2010 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 F Soak Period (Hole Still Intact, Hole Dry,Depth to Water Remaining in Hole,Etc.): On November 19, 2010 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 Fjj the minimum County requirements. 6.5 The Test Conformed to San Joaquin County Policy EHD 02-02 (Correct Depth, diameter, F 2" gravel, 6" water Refill, Correct Readings Recorded): The percolation test conformed to San Joaquin County Policy EHD 02-02.
