<br />CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE CITY <br />OF FORT COLLINS, LARIMER COUNTY, COLORADO, UNDER THE NATIONAL FLOOD <br />INSURANCE PROGRAM <br /> <br />On March 18, 1996, the Department of Homeland Security's Federal Emergency Management Agency <br />identified Special Flood Hazard Areas (SFHAs) in the City of Fort Collins, Larimer County, Colorado, <br />through issuance of a Flood Insurance Rate Map (FIRM). The Mitigation Division has determined that <br />modification of the elevations of the flood having a I-percent chance of being equaled or exceeded in any <br />given year (base flood) for certain locations in this community is appropriate. The modified Base Flood <br />Elevations (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 (Public <br />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 US.C. <br />4001-4128, and 44 CFR Part 65. <br /> <br />A hydraulic analysis was performed for Spring Creek to incorporate updated cross-section alignments, <br />topographic information, and floadway encroachments and the effects of construction of an irrigation <br />pond from approximately 4,300 feet downstream to approximately 1,600 feet upstream of West <br />Horsetaath Road. This has resulted in a revised delineation of the regulatory floadway, increases and <br />decreases in SFHA width, and increased and decreased BFEs for Spring Creek. The table below indicates <br />existing and modified BFEs for selected locations along the affected lengths of the flooding saurce(s) <br />cited above. <br /> <br />Location <br /> <br />Existing BFE <br />(feet)' <br /> <br />Modified BFE <br />(feet)' <br /> <br />Approximately 2,900 feet downstream <br />of West Horsetooth Road <br />Approximately 250 feet downstream <br />of West Horsetaoth Road <br /> <br />5,110 <br />5,134 <br /> <br />5,112 <br />5,135 <br /> <br />'National Geodetic Vertical Datum, rounded to nearest whole foot <br /> <br />Under the above-mentioned Acts of 1968 and 1973, the Mitigation Division must develop criteria for <br />floodplain management. To participate in the National Flood Insurance Program (NFIP), the community <br />must use the modified BFEs to administer the floodplain management measures of the NFIP. These <br />modified BFEs will also be used to calculate the appropriate flood insurance premium rates for new <br />buildings and their contents and for the second layer of insurance on existing buildings and contents. <br /> <br />Upon the second publication of notice of these changes in this newspaper, any person has 90 days in <br />which he or she can request, through the Chief Executive Officer of the community, that the Mitigation <br />Division reconsider the determination. Any request for reconsideration must be based on knowledge of <br />changed conditions or new scientific or technical data. All interested parties are on notice that until the <br />90-day period elapses, the Mitigation Division's determination to modify the BFEs may itself be changed. <br /> <br />Any person having knowledge or wishing to comment on these changes shonld immediately notify; <br /> <br />The Honorable Ray Martinez <br />Mayor, City of Fort Collins <br />P.O. Box 580 <br />Fort Collins, CO 80525 <br />
