The Assessor's Parcel Number <br /> Fis APN 105-220-01. The property is approximately 10 acres in size. <br /> F, You have requested that our office conduct a deep and shallow percolation test on the site. These <br /> borings were drilled at the requested locations indicated on the tentative parcel map,based on your <br /> conceptual plans for the site of the proposed septic system disposal area. <br /> The drilling of the shallow and deep soil boring was conducted on September 14, 2006 using a truck <br /> mounted deep rock auger rig. The soil log is shown in the following table. <br /> Soil Boring Lo <br /> Depth Interval(ft) Soil Type Unified Soil Classification <br /> F, 0-5 Dark brown sandy silt SM <br /> 5-15 Dark brown silty clay with some sand CL, <br /> 15-20 Brown sandy silt with some cla SM <br /> t-y Note:Conditions were comparable in the shallow boring <br /> The 20 foot deep boring and three foot shallow boring on the parcel were used for the percolation <br /> tests. Within the boring, about an inch of"pea gravel"was placed in the bottom of the hole to <br /> stabilize the side wall from caving and prevent erosion while filling the boring. A 2-inch diameter <br /> PVC pipe with open ends and slots was placed in the hole. About 6-inches of pea gravel was placed <br />' in the annular space around the pipe. The hole was pre-soaked 24 hours prior to the test with 12 <br /> inches of water above the bottom of the hole. Presoaking of the percolation test hole occurred <br /> 1 LODI ■ SACRAMENTO ■ MODESTO ■ RENO <br /> a.
