CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE CITY OF GOLDEN, JEFFERSON COUNTY, COLORADO, UNDER THE NATIONAL FLOOD INSURANCE PROGRAM On May 15, 1985, the Federal Emergency Management Agency (FEMA) identified Special Flood Hazard Areas (SFHAs) in the City of Golden, Jefferson County, Colorado, through issuance of a Flood Insurance Rate Map (FIRM). The Mitigation Directorate has determined that modification of the elevations of the flood having a I-percent chance of being equaled or exceeded in any given year (base flood) for certain locations in the City of Golden is appropriate. The modified base flood elevations (BFEs) revise the FEMA FIRM for the community . The changes are being made pursuant to Section 206 of the Flood Disaster Protection Act of 1973 (Public Law 93-234) and are in accordance with the National Flood Insurance Act of 1968, as amended (Title XIII of the Housing and Urban Development Act of 1968, Public Law 90-448),42 V.S.C. 4001-4128, and 44 CFR Part 65. A hydraulic analysis was performed to incorporate mor detailed topographic information and the effects of fill and channel modifications along West Fork Kenneys Run and has resulted in a revised delineation of the SFHA, and modified BPEs from approximately 1,350 feet downstream of Welch Ditch to Illinois Street. The table below indicates the modified BFEs for several locations along the affected length of West Fork Kenneys Run. Location Existing BFE (feet)* Modified BFE (feet)* Approximately 1,350 feet downstream of Welch Ditch Approximately 850 feet downstream of Welch Ditch Approximately 500 feet downstream of Welch Ditch Just downstream of Illinois Street 5,770 5,778 5,784 5,819 5,770 5,777 5,785 5,819 *National Geodetic Vertical Datum, rounded to nearest whole foot Under the above-mentioned Acts of 1968 and 1973, the Mitigation Directorate must develop criteria for floodplain management. For the community to participate in the National Flood Insurance Program (NFIP), the community must use the modified BPEs to administer the floodplain management measures of the NFIP. These modified BPEs will also be used to calculate the appropriate flood insurance premium rates for new buildings and their contents and for the second layer of insurance on existing buildings and contents. Upon the second publication of notice of these changes in this newspaper, any person has 90 days in which he or she can request, through the Chief Executive Officer of the community, that the Mitigation Directorate reconsider the determination. Any request for reconsideration must be based on knowledge of changed conditions or new scientific or technical data. All interested parties are on notice that until the 90-day period elapses, the Mitigation Directorate's determination to modify the BFEs may itself be changed Any person having knowledge or wishing to comment on these changes should immediately notify: The Honorable Jan C. Schenck Mayor, City of Golden City Hall 911 Tenth Street Golden, Colorado 80401
