<br />. <br /> <br />. <br /> <br />. <br /> <br />Purpose <br /> <br />This report was prepared to identify the outline of <br />the existing lOO-year floodplain along a study reach of Anthracite <br />Creek near Erickson Springs in Gunnison County, Colorado. The <br />information was needed in time to be considered for planning , <br />purposes prior to a presentation at a public meeting scheduled to <br />be held in Somerset, Colorado, on July 31, 1977, and at subsequent <br />meetings. Development of general floodplain information is in- <br />tended to assist county officials with land use planning and with <br />the evaluation of the flood hazard in their jurisdiction. <br /> <br />Due to the short time available, the scope of work has <br />been necessarily limited to the identification of the,~xisting <br />floodplain only and does not include any of the following items, <br />which may also be of interest to planners: . <br /> <br />1. Detailed topographic mapping. <br /> <br />2. Rigorous application of detailed hydrologic and <br />hla~ele~ie aBa hydraulic methods. <br /> <br />3. Investigation of proposals for future dam sites <br />on Anthracite Creek which may have an impact on <br />the existing floodplain. <br /> <br />4. Economic feasibility investigations of structural <br />improvements, such as channelization, to reduce <br />the flooded area. <br /> <br />5. Preliminary engineering and/or planning for <br />townsite or subdivision development. <br /> <br />4 <br />
