<br />~ <br /> <br />, <br /> <br />CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE <br />CITY OF FORT COLLINS, LARIMER COUNTY, COLORADO, UNDER THE NATIONAL <br />FLOOD INSURANCE PROGRAM <br /> <br />On March 18, 1996, the Federal Emergency Management Agency identified Special Flood Hazard <br />Areas (SFHAs) in the City of Fort Collins, Larimer County, Colorado, through issuance of a Flood <br />Insurance Rate Map (FIRM). The Mitigation Directorate has determined that modification of the <br />elevations of the flood having a I-percent chance of being equaled or exceeded in any given year (base <br />flood) for certain locations in this community is appropriate. The modified base flood elevations <br />(BFEs) revise the FIRM for the community. <br /> <br />The changes are being made pursuant to Section 206 of the Flood Disaster Protection Act of 1973 <br />(Public Law 93-234) and are in accordance with the National Flood Insurance Act of 1968, as amended <br />(Title XIII of the Housing and Urban Development Act of 1968, Public Law 90-448), 42 U.S.C. <br />4001-4128, and 44 CFR Part 65. <br /> <br />A hydraulic analysis was performed to incorporate a channelization and bridge and levee construction <br />project along the Cache La Poudre River from approximately 3,100 feet upstream to approximately <br />8,000 feet upstream of Prospect Road and has resulted in a revised delineation of the regulatory <br />floodway, increases and decreases in SFHA width, and increased and decreased BFEs for the Cache La <br />Poudre River and Cache La Poudre LPATH. The construction of the levee prevents the overland flow <br />originating from the Cache La Poudre River from entering the Cache La Poudre RPATH. As a result <br />of the levee construction and channelization, Cache La Poudre RP A TH and its associated flood hazards <br />have been eliminated. The table below indicates existing and modified BFEs for selected locations <br />along the affected lengths of the flooding source(s) cited above. <br /> <br />Location <br /> <br />Existing BFE Modified BFE <br />(feet)* (feet)* <br />4,902 4,903 <br />4,907 4,908 <br />4,918 4,916 <br />4,891 4,892 <br />4,894 4,892 <br />4,909 4,907 <br /> <br />Cache La Poudre River: <br />Approximately 2,000 feet upstream of Prospect <br />Road <br />Approximately 3,400 feet upstream of Prospect <br />Road <br />Approximately 6,200 feet upstream of Prospect <br />Road <br /> <br />Cache La Poudre LPATH: <br />Approximately 100 feet upstream of Prospect Road <br />Approximately 1,800 feet upstream of Prospect <br />Road <br />Approximately 6,200 feet upstream of Prospect <br />Road <br /> <br />Cache La Poudre RPATH: <br />Approximately 1,000 feet upstream of confluence <br />with Cache La Poudre River <br />Approximately 3,000 feet upstream of confluence <br />with Cache La Poudre River <br />Approximately 5,000 feet upstream of confluence <br />with Cache La Poudre River <br /> <br />4,901 <br />4,905 <br /> <br />None <br /> <br />None <br /> <br />4,912 <br /> <br />None <br />
