4-86 (Wischmeier, 1971). K factors are rated good or fair for • most soils; the Alluvial lands soils is rated poor. Wind erodibility is based on soil textural class and lime content and rated by SCS criteria (USDA-SCS, 1974). Most soils are rated good or fair throughout. The Alluvial lands soil is rated poor. The roadfill is rated good or fair. USDA texture influences available water capacity and erodi- bility by wind or water. Texture also influences soil structure, consistence, water intake- rate, runoff, fertility, workability, and trafficability. Potential slippage hazard is related to soil texture, and although other factors also contribute, the ratings of soil texture represent one important factor (USDA, 1978). Soil textures are rated good to fair for • soils of the site, but are generally not considered the limiting factors. The alluvial land soils are too sandy and are rated fair in the surface soil and poor in the substratum. The textures of the roadfill material are rated fair in all samples except one. Coarse fragments influence the ease of excavation, stockpiling and respreading, and suitability for the final use of the land. A certain amount of coarse fragments can be tolerated depending upon the size and the intended use of the reclaimed area. If the size of rock fragments exceed 10 inches (25 cm) the problems are more severe (USDA, 1978). Coarse fragments are evaluated based on pedon descriptions for soils of site. Most soils • are rated good throughout. Few horizons tested have more than 15 percent coarse fragments larger than 3 inches and are rated fair.
