<br />CHANGES ARE MABE 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 Federal Emergency Management Agency identified Special Flood Hazard Areas
<br />(SFHAs) in the City of Fort Collins, Larimer County, Colorado, through issuance of a Flood Insurance
<br />Rate Map (FIRM), The Mitigation Directorate has determined that modification of the elevations of the
<br />flood having a l'percent chance of being equaled or exceeded in any given year (base flood) for certain
<br />locations in this community is appropriate. The modified Base Flood Elevations (BFEs) revise the FIRM
<br />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 U.S,C,
<br />4001-4128, and 44 CPR Part 65,
<br />
<br />A hydraulic analysis was performed to incorporate the effects of three bridge replacement projects within
<br />three separate reaches along Spring Creek: from approximately 550 feet downstream to approximately
<br />1,350 feet upstream of Welch Street; from approximately 1,400 feet downstream to approximately
<br />950 feet upstream of Remington Street; and from approximately 1,300 feet downstream to approximately
<br />1,050 feet upstream of West Drake Road, This has resulted in a revised delineation of the regulatory
<br />floodway, increases and decreases in SFHA width, and increased and decreased BFEs for Spring Creek
<br />Because the increases in BFE are not large enough to change the whole,foot BFEs shown on the effective
<br />FIRM, the increases will not be published, The table below indicates existing and modified BFEs for
<br />selected locations along the affected lengths of the flooding source(s) cited above,

<br />Approximately 470 feet downstream of Remington Street
<br />Approximately 150 feet upstream of College Avenue
<br />Approximately 300 feet downstream of West Drake Road
<br />Approximately 650 feet (distance measured along Profile
<br />Baseline A) upstream of West Drake Road

<br />
<br />Under the above,mentioned Acts of 1968 and 1973, the Mitigation Directorate 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 />Directorate 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 Directorate's determination to modify the BFEs may itself be
<br />changed,
