<br />The Spring Creek basin does not have any flood contI'OI stlUctures below Horsetooth Reservoir. <br />The City of Fort Collins has, however, channelized portions of the Spring Creek channel, and <br />improved culverts and bridges in order to reduce the flood hazard and remove people and <br />property from the floodplain. <br /> <br />Dry Creek has several lakes and storage reservoirs which reduce the contributing drainage area <br />by approximately 13 percent, although they are not realIy flood control structures. Douglas <br />Lake, located outside Fort Collins corporate limits is also an irrigation reservoir that provides <br />about 15%,20% flood flow attenuation for the 100-year event. <br /> <br />Boxelder Creek has approximately 75% of its contributing drainage basin controlled by Soil <br />Conservation Service (SCS) Flood Control reservoirs m:ar Wellington. The SCS flood l:ontrol <br />reservoirs have substantially reduced the flood peaks in the vicinity of Fort Collins. <br /> <br />Fossil Creek drains from the edge of the foothills through Fort Collins and into Fossil Creek <br />Reservoir. There are no flood control structures upstream of Fossil Creek Reservoir. <br /> <br />II. FLOODPLAIN STUDIES <br /> <br />Purpose of Studying Floodplains <br /> <br />I. To minimize the loss to life ,md property, <br /> <br />2. To develop and disseminate the most accurate information obtainable on flooding. <br /> <br />3. To educate the public to the hazards of flooding. <br /> <br />4. To determine actuarial rates for flood insurance. <br /> <br />5. To provide flood prone communities, such as Fort Collins, with information necessary to <br />implement floodplain management meas\Ues. <br /> <br />Flood Insurance Studies <br /> <br />In 1979 the Federal Emergency Management Agency (FEMA) published the Flood Insurance <br />Study (FIS) for the City of Fort Collins, Larimer COWlty, Colorado. The purpose of the FIS was <br />to investigate the existence and severity of flood hazards in the City of Fort Collins and to aid in <br />the administration of the National Flood Insurance Act of 1968 wd the Flood Disaster Protection <br />Act of 1973. Initial use of the information was to convert the City of Fort Collins to the regular <br />program of flood insurance by the FEMA. Further use of the information is made by the City to <br />promote sound land use and floodplain development. <br /> <br />17 <br />
