EXHIBIT I Soil Information At the end of this exhibit are some printouts from the NRCS website that describe many of the typical characteristics of the soils present on the site. Please refer to Exhibit C -2, Soils Map, for an illustration showing the distribution of the soils. According to the Web Soil Survey (United States Department of Agriculture, NRCS, 2004) of the proposed permit area, there are three major soil types within the proposed project site: 1. Altvan and Ascalon fine sandy loams and 2. Peetz gravely sandy loam. The location of these soil types is illustrated on Exhibit C -2, Soils Map. Traditional organic topsoil on most of the site is thin or non - existent. Most of the soils are shallow to deep loams that are well drained. Over most of the identified sand and gravel deposit is a loamy, wind -mixed veneer layer of soil overburden material varying in depth from less than one inch to six feet. The soil overburden material likely developed from alluvial and eolian deposits of clay, silts, and sands. Over time, erosive forces of wind and water have influenced the soils on the site. Mobile soil particles, such as silt and clay, have eroded from higher topographic positions and have been re- deposited in lower areas. Therefore, Swale areas may have finer textured soils than ridgetops. Altvan and Ascalon Fine Sandy Loams The Altvans and Ascalons are found on level and nearly level (0 to 6 percent slopes) land forms. Located on loamy plains throughout the area, these soil types are well drained and classified as Hydrologic Soil Group B. They are also the most dominant soil types within the proposed project site. The water table is typically more than 80 inches below the soils. Areas containing these soils are used mainly for rangeland and wildlife habitat. Their water holding capacity is low to moderate and typically do best as seeded rangeland. These soils produce low plant densities of Blue Grama/Buffalo Grass sod with excessive ground litter. Peetz Gravely andy Loam The Peetz is found on 5 to 20 percent slopes and located on land form breaks and ridges. This soil type is somewhat excessively drained and classified as Hydrologic Soil Group A. The water table is typically more than 80 inches below the soil. Areas containing this soil type are used mainly for rangeland and wildlife habitat. Its water holding capacity is low and typically supports Blue Grama sod with bare ground, cryptogam, and annual plant communities. Connell Carr Pit DRMS 112 Permit Application Page 21
