Surface and Subsurface Contamination Report—APN: 009-110-04—To create a homesite parcel contain- ing five(5)acres within an existing forty(40)acres parcel leaving a thirty-five acres parcel,Parcel 2. acid. The upper topsoil, which extends to about 16 inches, is red, slightly compact, and The next 10 inches is compact clay, which is very plastic and stiff. The lower subsoil underlies this and is red or grayish-red, gravelly or stony, iron-cemented hardpan about 8 to 10 inches in thickness. The underlying material is a permeable mass of gravel and cobbles. These soils occupy high terraces and represent remnants of old valley-filling material on rolling to hilly slopes with hogwallow microrelief. Drainage is slow and restricted by the hardpan; erosion is active on the steeper slopes. The soil supports short grass, and grain may be produced on the flatter, less gravelly areas, but most of this is in range pasture. The Redding soils are widely distributed over the eastern part of the county. The University of California publication entitled"Soils of San Joaquin County, California,United States Department of Agricultural Soil Conservation Service", issued October 1992, also lists the soil to be encountered on the subject property as Redding Gravelly Loam. Water is briefly perched above the claypan after periods of heavy rainfall or irrigation. Runoff is slow or medium, and the hazard of water erosion is slight or moderate. The rate of water intake in irrigated areas isl.5 inches per hour. Most areas are used for livestock grazing. A few areas are used as irrigated pasture or for dryland grain crops. This unit may provide wetland features and values. These should be considered in plans for enhancement of wildlife habitat or hand use conversion such as the already existing pond located north of the property owner's home. When the land is used for livestock grazing, general management considerations include saturated conditions in concave areas following rainy periods, hazard of erosion, and the very low water capacity. Grazing should be controlled so that desirable vegetation is maintained and enough vegetation is left standing to protect the soil from erosion. Where suited for irrigation pasture the main limitation is irrigation. Because the soil is droughty, applications of water should be light and frequent. Apply water by sprinkler and border methods. Where the land is used for dryland grain crops, all tillage should be on the contour or across the slope. Leaving crop residue on or near the surface helps to conserve moisture.
