<br />CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE <br />TOWN OF WINDSOR, WELD COUNTY, COLORADO, UNDER THE NATIONAL FLOOD <br />INSURANCE PROGRAM <br /> <br />On September 27, 1991, the Federal Emergency Management Agency identified Special Flood Hazard <br />Areas (SFHAs) in the Town of Windsor, Weld 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 I-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 CFR Part 65. <br /> <br />A hydraulic analysis was performed to incorporate corrections to the alignment of County Road 17 and <br />the geometry of Eastman Park Drive for superelevation, updated topographic information, and <br />optimization of the floodway along the profile baseline for the Cache la Poudre River from just <br />downstream to approximately 3,000 feet upstream of the corrected alignment of County Road 17. This <br />has resulted in increased and decreased BFEs and a revised delineation of the regulatory floodway along <br />the profile baseline for the Cache la Poudre River and decreased BFEs for County Road 17 Divided Flow. <br />The table below indicates existing and modified BFEs for selected locations along the affected lengths of <br />the flooding source(s) cited above. <br /> <br />Location <br /> <br />Existing BFE <br />(feet)" <br /> <br />Modified BFE <br />(feet)" <br /> <br />Cache La Poudre River: <br />Just downstream of corrected <br />alignment of County Road 17 <br />Approximately 1,900 feet upstream of <br />corrected alignment of County Road 17 <br />along profile baseline <br /> <br />4,763 <br /> <br />4,762 <br /> <br />4,768 <br /> <br />4,769 <br /> <br />County Road 17 Divided Flow: <br />Approximately 200 feet downstream of <br />County Road 17 <br /> <br />4,763 <br /> <br />4,762 <br /> <br />"National Geodetic Vertical Datum, rounded to nearest whole foot <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 />
