Soil Suitability Study—APN: 005- 141 —29—PA-03587 Parcel No. 1,Approximately 2.0 Acres Total thickness from a few inches to 18 inches or more. Sometimes the hardpan contains a little lime. (5) Below the hardpan the material becomes friable and stratified. The soil occupies a gently sloping terraced topography with distinct hog-wallow micro-relief. After having saturated the topsoil to the clay layer, water will stand on the surface until it evaporates. Erosion is negligible. Permeability is good surface and good subsurface,both. San Joaquin soils are dry-farmed to grain. The yield is good, in favorable rainfall years. Irrigated pasture is grown successfully, but deep-rooted crops are undesirable. Grass and a few shrubs are the native vegetation. San Joaquin loam, deep has a Storie Index of 30. San Joaquin soils occur extensively in the eastern part of San Joaquin County. The University of California publication entitled"Soils of San Joaquin County, California, United States Department of Agricultural Soil Conservation Service", issued October 1992, lists the soil to be encountered on the subject property as San Joaquin Urban Land Complex(0-2%). SAN JOAQUIN-URBAN LAND COMPLEX, 0 TO 2 % This soil is on low terraces at elevations varying from 20 to 110 feet. This soil is composed of 50% San Joaquin loam and 35% urban land. These components are so intricately intermingled that it is not possible to map them separately. Included in this soil classification are small areas of Kingdon and Tokay soils on the higher parts of the slope. Also in this classification are small areas of moderate textured soils that have a hardpan at a depth of twenty(20) inches and moderately coarse textured soils that have been ripped and have remnants of claypan and hardpan material. Included areas make up about 15% of the total acreage. This soil is moderately deep to a hardpan and is moderately well drained. It formed in alluvium derived from granitic rock sources. Typically, the surface layer and the upper part of the subsoil are brown loam about 16 inches thick. The next ten(10) inches of the subsoil is a claypan of brown clay. The lower part to a depth of sixty(60) inches is a brown and light brown indurated hardpan. Permeability is slow and available water capacity is low. The shrink-swell is high. Water is briefly perched above the claypan and hardpan after periods of heavy rainfall. Runoff is slow, and the hazard of water erosion is slight. The rate of water intake in irrigated areas is 1.0 inches per hour. For MatriScope Inc.-25655 North State Highway Rte 99,West Frontage Road,Acampo, CA 95220— 5
