<br />1.3 Coordination <br /> <br />On April 9, 1984, Dames & Moore was instructed by FEMA to proceed <br />with an Existing Data Study for the Town of Carbondale, Colorado, <br />using the study data from the Garfield County Flood Insurance Study. <br /> <br />The results of the hydrologic analyses were coordinated with the <br />U.S. Army Corps of Engineers (COE) , the Colorado Water Conservation <br />Board, and the U.S. Geological Survey (USGS). <br /> <br />The final community coordination meeting was held on January 28, <br />1985, and was attended by representatives of FEMA, the study <br />contractor, and the town. No problems were raised at the meeting. <br /> <br />2.0 AREA STUDIED <br /> <br />2.1 Scope of Study <br /> <br />This Flood Insurance Study covers the incorporated areas of the <br />Town of Carbondale, Garfield County, Colorado. The area of study <br />is shown on the Vicinity Map (Figure 1). <br /> <br />Flooding caused by the overflow of the Crystal River was studied <br />in detail. <br /> <br />The areas studied by detailed methods were selected based on the <br />extent and validity of available hydrologic and hydraulic data. <br /> <br />2.2 Community Description <br /> <br />The Town of Carbondale is located in southeast Garfield County, in <br />west-central Colorado.
