Larry Routten and Erica Crosby -3- November 3, 1993 There are two general vegetation community types within the West Pit diversion drainage basin. These are the grassland community and the Ponderosa Pine/PirSon-Juniper woodland community. The respective areas covered by each community type were digitized from the Figure 5 map, which was drawn using the USGS Quadrangle map and the soils information provided by the Soil Conservation Service (SCS). The soils information is discussed in more detail below. The vegetation community distributions are summarized as follows: . .Acres. Percent of Tdtal Area Grassland 123 28 Woodland 348 72 ,..... Total Basin'.:: :.,435 ,.... 100 Soil Tvoes The soil types and soil distributions were derived from soil mapping data obtained from the Canon City office of the United States Soil Conservation Service. The maps and descriptions (Exhibit A) were received by DMG on November 3-4, 1993. The soil distributions were mapped within the drainage basin, at a scale of 1 inch = 2,000 feet (Figure 5). The mapped units were then digitized to determine the approximate acreage values associated with each soil type. Hydrologic Soil Group designations were derived in accordance with the designations listed by the U.S. Department of Agriculture (1983), the U.S. Department of Agriculture (1986), and the information transmitted directly from the Canon City SCS personnel. The results of this analysis and the Hydrologic Soil Group designations used for each soil group are depicted below. Soils Distribution.
