<br />1.3 Authority and Acknowledgments <br /> <br />The source of authority for this Flood Insurance Study is the National <br />Flood Insurance Act of 1968, as amended. <br /> <br />The hydrologic and hydraulic analyses for this study were performed <br />by the U.S. Army Corps of Engineers, Sacramento District, for the <br />Federal Insurance Administration under Inter-Agency Agreement No. <br />IAA-H-16-75, Project Order No. 17. This work, which was completed in <br />April 1976, covered all significant flooding sources affecting the <br />City of Steamboat Springs. <br /> <br />2.0 AREA STUDIED <br /> <br />2.1 Scope of Study <br /> <br />This Flood Insurance study covers the Town of Steamboat Springs, <br />Routt County, Colorado. The area of study is shown on the Vicinity <br />Map (Figure 1). <br /> <br />The Yampa River flows on a northwesterly course through Steamboat <br />Springs and is joined by Soda, Butcherknife, Spring, Fish, and <br />Walton Creeks in the city. Substantial d~vclopment is expected <br />generally throughout the study area. It was agreed by the city and <br />county, the Federal Insurance Administration, and the U.S. Army Corps <br />of Engineers that all of the streams named above, plus the lower <br />reach of Burgess Creek (a tributary to Walton Creek), would be <br />studied by detailed methods. The stream reaches agreed upon for <br />study by approximate methods comprise Burgess Creek, upstream from <br />Storm Meadows Road, and the portions of unnamed tributaries to Fish, <br />Burgess, and Walton Creeks in the city. <br /> <br />The areas studied by detailed methods were chosen with consideration <br />given to forecasted development through June 1981. <br /> <br />2.2 Community Description <br /> <br />The town is located in the east-central portion of the county, which <br />is on the western slope of the Continental Divide in the northwestern <br />sector of Colorado. By principal highways, steamboat Springs is <br />located approximately 170 miles northwest of Denver and 120 miles <br />southwest of Laramie, Wyoming. There are no other major urban <br />centers in the region. The city is situated at an elevation of <br />approximately 6700 feet National Geodetic vertical Datum of 1929 <br />(NGVD). Its setting is alpine in nature, with mountain peaks rising <br />to approximately 10,000 feet NGVD in the immediate area. <br /> <br />Figure 2 provides a panoramic view of the Town of steamboat Springs. <br /> <br />3 <br />
