LIlVIITED IMPACT 11~LICATION FOR PIT NUMBER ONE APPLICANT: MARILYN VAZQUEZ/BRUCE DIAMOND EXHIBIT B SITE DESCRIPTION (Page 1 of 3) • General Site Characteristics The general character of this site and the surrounding area is open, generally flat, and rocky. The site is at approximately 7800 feet elevation and receives approximately 12 inches of rain per year. Due to climate, soil and sparse native vegetation, it supports minimal livestock without irrigation. • Vegetation Existing vegetation on this site is sparse, approximately 40%. Primary species are blue gramma grass and Indian rice grass; other species in minimal amounts are yucca and cactus. According to the Soil Conservation Service (SCS)*, vegetation associated with the Ouray gravelly loam (OuB) is bunchgrass such as Indian ricegrass and needle-and-thread. For the San Isabel stony sandy loam (SsC), vegetation is bunchgrass such as junegrass, bunch bluegrass and Indian ricegass. • Soils Large and small cobbles, and up to medium size boulders are abundant on the surface, covering approximately 20% of the site. According to mapping by the SCS, the soil types on this site are approximately 70% Ouray gravelly loam, thick surface variant, i to 3 percent slopes (OuB) and 30% San Isabel stony sandy loam 1 to 5 percent slopes (SsC). The following is reprinted from the Soil Conservation Service report noted herein: OuB This soil is on terraces that parallel the main river and streams in the central and northern parts of Chaffee County, generally east of the Arkansas River. Included with this soil in mapping are small areas of Dominson gravelly sandy loam, 1 to 9 percent slopes. Southwest of Salida and Southeast of Buena Vista, there aze azeas of included soils that are less than 40 inches deep over cobbles and gravel and are slightly calcareous within 12 inches of the surface. Also included are small areas of Ouray soils that have a surface layer of gravelly sandy loam. Runoff is slow on this soil, and the hazard of erosion is shght. Most of the acreage is irrigated and used for crops, mainly alfalfa hay, potatoes and small grains. * Soil Survey of Chaffee-Lake Area, Colorado, Parts of Chaffee and Lake Counties, prepared by the Unites States Department of Agriculture Soil Conservation Service in Cooperation with Colorado Agricultural Experiment Station, Issued October, 1975.
