drainage dominates the valley setting in the neighboring area. Surrounding Land Uses are depicted on an accompanying map that shows the configuration of various properties in relationship to the subject sde. A study of the surrounding land uses includes all of the properties within about a Y. mile radius of the site. 17 indnridual parcels were studied. All but 4 of the parcels contained a single family dwelling. Review of the Surrounding Land Use map reveals that most of the dwellings are located east of the site across the river along County Road 250. The dwellings nearest the site are owned by the land owners of the leased area. ACCESS -The epsting highway and access serving the site are well maintained and are in good condition. Access to the site is gained from US Highway 550 which is paved with gravel shoulders and no sidewalks. The Colorado Department of Transportation classifies US Highway 550, at the site's access drive as, "having the capacity for medium to high speed or medium to high volume traffic movements over medium and long distances and provides inter regional, inter-city, and intracily travel needs." Most of the material removed from the site is to the delivery points north of Durango. SOILS AND GEOLOGY-0ther than flooding by the river, (discussed below) no other natural or man made geologic hazards are known to east in the area of site. The US Department of Agriculture, Soil Conservation Service, has ident~ed two soil classifications within site. A general description follows: Werlow Loam (AOB) -Found mainly on the upper terrace level of the site are deep or moderately deep sails overlying river sand and gravel. The surface is a loam about 10 thick. This overlies loam strat~ed with sandy loam. The soil has a moderately high ground water table and is subject to flooding. RIVERWASH (R1n -This soil unit consists of gravelly and cobbly alluvial materials that are along rivers. It is subject to frequent flooding and deposition of new materials. DRAINAGE -The permit area is not prone to flooding from adjoining properties. The predominate drainage course found in the vicinity of the site is the Animas River which flows adjacent to the ste's easterly boundary. A review of the Flood Rate Insurance Map and mapping conducted by the Army Corps of Engineers COE) indicate that part of the site is prone to flooding by the Animas River during a 100 year flood event. Water measurement taken for more than 100 years has shown a peak flow in the river of 25,000 cubic feet per second in 1912 near Durango. During the recording period, average peak flows were recorded as, 5,100 cubic feet per second. According to the COE the elevation of the 100 year flood event is about 8.5 feet above the river bed elevation adjacent to the site.
