<br />r- <br />oo <br />C'j <br /> <br />Evaluation Area A - Soils <br /> <br />This area is comprised of deep, medium to fine textured soils on slopes <br />ranging from 0 to 6 percent. They have weakly to strongly developed B <br />horizons with corresponding moderate to slow permeability. About 17 per- <br />cent of the acreage consists of soils underlain by gravel at depths between <br />20 and 48 inches. Depth to shale is over 60 inches. Most of the project <br />soils having saline, alkali and high water table problems, are included <br />in this evaluation area. There are 2,302 acres or 71 percent of soils <br />grouped into capability class III and 916 acres or 29 percent grouped into <br />capability class II. <br /> <br />Evaluation Area B - Soils <br /> <br />Soils in this evaluation area are gen<=~lly deep, predominantly medium <br />textured, have weakly to strongly developed B horizons, moderate to slow <br />permeabillty, and slopes ranging from 3 to 12 percent. Thirty-five percent <br />of this acreage consists of soils underlain by gravel between 12 and 48 <br />inches. Depth to shale is over 60 inches. A SIlI.all acreage is affected <br />by salt, alkali, high water table and flooding. This evaluation area <br />includes most of the moderately stony soils on the project. Steep slope <br />is the major soil problem affecting the capability classification. All <br />the soils comprising the 1,462 acres in this evaluation area are grouped <br />into capability class IV. <br /> <br />Evaluation Area C - Soils <br /> <br />Soils of this evaluation area have developed primarily from loess; however, <br />a SIIIa11 acreage has developed from alluvium. They are deep, medium tex- <br />tured soils with weakly to strongly developed B horizons, moderate to slow <br />permeability, and slopes ranging from 1 to 6 percent. A small acreage of <br />soils is underlain by gravel at depths between 30 and 48 inches. Slope <br />as it affects the soil erosion potential is the only significant problem <br />affecting the capabil ity c1assif.ication of these soils. There are 407 <br />acres or 62 percent of the soils grouped into capability class II and 250 <br />acres or 38 percent grouped into capability class III. <br /> <br />Evaluation Area D - Soils <br /> <br />'Ibi s evaluation area is comprised of deep, med ium textured soils which pre- <br />dominantly have weakly developed B horizons, moderate permeability, and <br />slopes ranging from 6 to 12 percent. A small acreage of soils, representing <br />about 13 percent of this area, is underlain by gravel at depths between <br />20 and 48 inches. Except for a small acreage that is slightly affected <br />by salt and a1ka! i, the only soil problem is slope as it affects the soil <br />erosion potential. All the soils in this evaluation area (215 acres) are <br />grouped into capability class IV. <br /> <br />- 12 - <br />
