<br />.. <br /> <br />.' <br /> <br />CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR TIlE <br />TOWN OF ERIE, BOULDER AND WELD COUNTIES, COLORADO, UNDER THE NATIONAL <br />FLOOD INSURANCE PROGRAM <br /> <br />On September 28, 1990, the Department of Homeland Security's Federal Emergency Management <br />Agency identified Special Flood Hazard Areas (SFHAs) in the Town of Erie, Boulder and Weld Counties, <br />Colorado. through issuance of a Flood Insurance Rate Map (FIRM). The Mitigation Division has <br />detennined that modification of the elevations of the flood having a I,percent chance of being equaled or <br />exceeded in any given year (base flood) for certain locations in this community is appropriate. The <br />modified Base Flood 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 U.S.C. <br />4001-4128, and 44 CFR Part 65. <br /> <br />A hydraulic analysis was perfonned to incorporate the effects of the Vista Pointe Parkway bridge and <br />development project along Coal Creek and more detailed topographic information from approximately <br />200 feet liownstream of the Union Pacific Railroad to approximately 5,500 feet upstream of the Vista.: <br />Pointe, Parkway bridge. This has resulted in a revised delineation of the regulatory floodway, increases <br />and decreases in SFHA width, and increased and decreased BFEs for Coal Creek. The table below <br />indicates existing and modified BFEs for selected locations along the affected lengths of the flooding <br />source( s) cited above. <br /> <br />Location <br /> <br />Existing BFE <br />(feet)" <br /> <br />Modified BFE <br />(feet)" <br /> <br />Approximately 300 feet upstream of <br />Union Pacific Railroad <br />Approximately 200 feet upstream of <br />Vista Pointe Parkway bridge <br /> <br />5,023 <br /> <br />5,024 <br />5,066 <br /> <br />5,064 <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 detennination. 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 should immediately notify: <br /> <br />The Honorable Barbara Connor <br />Mayor, Town of Erie <br />P.O, Box 750 <br />Erie, CO 80516 <br />
