Soil Suitability Study—APN: 005 - 141 —29—PA-03587 Parcel No. 1,Approximately 2.0 Acres Total process and the interim time between excavation and formal testing to prevent anyone or animal from falling into the hole and hurting themselves. A yardstick bouyed by a float was used to measure the water level drops in the shallow percolation test hole and an electronic water detecting, measuring tape was used to measure the water level drops in the deep percolation test hole. Test Results are summarized as follows: Parcel No. Test Hole 3' Deep Percolation 25' Max. Deep Percolation Minimum Usable No. Rate (Minutes/Inch) Rate (Minutes/Inch) Disposal Area (Square Feet) 1 S 1 Failed to meet S.J. Co. Stds. No Recommends 1 DI 27.78 12,000 Sq. Ft. + Pits 4.0 Soil Profile and Groundwater Elevation: The San Joaquin County Flood Control and Water Conservation Map entitled"Lines of Equal Depth To Water Wells", dated spring 1998, shows the water table to be in excess of seventy(70) feet below the ground surface. No water was encountered in excavating any of the shallow and deep percolation test holes to a maximum depth of 18.57 feet. The Deep Percolation Test Hole D1 was selected to serve and is used as the Soil Profile Hole. 5.0 Soil Character: The University of California publication entitled "Soils of San Joaquin County, California",by Walter W. Weir, dated June 1952, identifies the soil on the subject property to be San Joaquin loam, deep. SAN JOAQUIN LOAM, DEEP San Joaquin loam deep soils are strongly developed hardpan soils and are derived from old alluvial deposits now occurring as terraces. They are composed largely of materials of granitic origin. The term "Red-Iron Hardpan Land"is commonly used to describe this soil. The soil is brownish-red, acid in reaction, and usually light to medium textured. Loam and sandy loam types are recognized in this soil classification. A typical profile of San Joaquin sandy loam follows: (1) To depth of about 9 inches, the soil is reddish brown, friable, easily penetrated by roots and water but bakes hard when dry. The pH is about 5.4. (2) From about 9 to 18 inches, the soil is redder and heavier textured. (3) From 18 to 24 inches,there is compact clay with suggestion of a prismatic structure. (4) The clay layer rests abruptly, at about 30 inches, on a yellowish-brown, iron cemented hardpan. The surface of this layer is very hard and it may vary in For MatriScope Inc.-25655 North State Highway Rte 99,West Frontage Road, Acampo, CA 95220 4
