Soil type#101*: This is 5%of the soil of the existing site, and no soil or water samples were collected or analyzed,due to the location of the facility operations in the soil type#149. Name: Acampo sandy loam, 0 to 2 percent slopes. This moderately well drained, nearly level soil is on low fan terraces. It is deep to a hardpan. It is formed in alluvium derived from granite rock sources. A few areas are dissected by intermittent soughs that have been filled as a result of land leveling. Elevation is 10-150 feet. The average rainfall precipitation is about 15 inches. The average annual air temperature is about 60 degrees F, and the average frost-free period is about 270 days. Typically, the surface layer is brown sandy loam about 19 inches thick. The upper part of the subsoil is pale brown and light yellowish brown sandy loam, which extends to a depth of 47 inches. The nest part is an indurated hardpan, which extends to a depth of 49 inches. The lower part to a depth of 60 inches is a variegated brownish yellow and yellowish brown, weakly cemented to strongly cemented hardpan. In some areas the surface layer is fine sandy loam or loam. Included in this unit are small areas of Devries and Tujunga soils in the slightly lower landscape positions and small areas of moderately coarse textured soils that have a moderately fine textured subsoil. Also included are small areas of Tokay soils in landscape positions similar to those of the Acampo soil. Included areas make up about 15 percent of the total acreage. Permeability is moderately rapid in the Acampo soil. Available water capacity is moderate. The effective rooting depth is limited by the hardpan at a depth of 40 to 60 inches. Depth to the water table is more than 6 feet, but water may be briefly perched above the hardpan after periods of heavy rainfall or irrigation. Runoff is slow, and the hazard of water erosion is slight. The rate of water intake in irrigated areas is 1.5 inches per hour. The hazard of soil blowing is moderate. Most areas are used for irrigated crops, orchards, or vineyards. A few areas are used for home site development. This unit may provide wetland functions and values. These should be considered in plans for enhancement of wildlife habitat or land use conversion. This unit is suited to irrigated row,field,orchard,and vineyard crops. The main limitation is depth to hardpan. General management considerations include the hazard of soil blowing. The hardpan limits the suitability for deep-rooted crops. Where feasible, deep ripping of this restrictive layer can help to overcome this limitation. A tillage pan forms easily if the soil is tilled when wet. Chiseling or sub-soiling breaks up the pan. Furrow, border, and sprinkler irrigation systems are suitable. Careful applications of irrigation water are needed to prevent the buildup of a high water table. When the wind velocity is high in spring, the hazard of soil blowing can be reduced by properly managing all crop residue and by minimizing tillage. If this unit is used for home site development, the main limitation is depth to the hardpan. Ripping the hardpan improves permeability and thus also improves the suitability of the soil for septic tank absorption field. This unit is in capability units IIs-8 (Nfl,RA-17), irrigated, and IVs-8 (MI.,RA-17), non-irrigated. It is in vegetative soil group A' Refer to Vegetative Groups, Appendix HE, and Land Capability Classification,Appendix IIF,for definitions. Land Capability Classification*: Land capability classification shows, in a general way, the suitability of soils for most kinds of field crops. The criteria used in grouping the soils do not include major and general expensive landforming that would change slope, depth or other characteristics of the soils, nor do they include possible but unlikely major reclamation projects. In the capability system, soils are generally grouped at three levels: capability class, subclass_ and unit. *!Vote:All of the soils at the dairy site have been leveled for some time.They have also been ripped to breakup the consolidated areas.They have also had organic materials(manure solids)applied that improves soil tilth,water holding capacity,water percolation rate,erasion and nutrient holding capacity. 1.U.S.D.A,Natural Resources Information—Vegetative Soil Groupe—July 2000 Pare 3 c Western Design/David Avila 2001 10
