Federal Emergency Management Agency Washington, D.C. 20472 CERTIFIED MAIL RETURN RECEIPT REQUESTED IN REPLY REFER TO: Case No.: 99-08-112P The Honorable Nancy M. Heil Mayor, City of Westminster 4800 West 92nd Avenue Westminster, CO 80030 Community: City of Westminster, Colorado Community No.: 080008 Panel Affected: 0007 D Ef~ective.~ate of APR 2 3 1999 ThIS RevIsIon: 102-I-A-C Dear Mayor Heil: This responds to a request that the Federal Emergency Management Agency (FEMA) revise the effective Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FIS) report for your community in accordance with Part 65 of the National Flood Insurance Program (NFIP) regulations. In a letter dated December 8, 1998, Ms. Sheila Beissel, P.E., Senior Civil Engineer, Department of Community Development, City of Westminster, requested that FEMA revise the FIRM and FIS report to show the effects of existing topographic information along Middle Branch Hylands Creek from approximately 400 feet upstream of West 99th Place to approximately 100 feet downstream of Raleigh Street. All data required to complete our review of this request were submitted with letters from Ms. Beissel. Because this Letter of Map Revision (LOMR) is being issued to correct a mapping or study analysis error, fees were not assessed for the review. We have completed our review of the submitted data and the flood data shown on the effective FIRM and FIS report. We have revised the FIRM and FIS report to modify the elevations and floodplain and floodway boundary delineations of the flood having a I-percent chance of being equaled or exceeded in any given year (base flood) along Middle Branch Hylands Creek from approximately 400 feet upstream of West 99th Place to approximately 100 feet downstream of Raleigh Street. As a result of the modifications, the base flood elevations (BFEs) and widths of the Special Flood Hazard Area (SFHA), the area that would be inundated by the base flood, and regulatory floodway for Middle Branch Hylands Creek increased in some areas and decreased in other areas. All property owners were notified of the revised BFEs and SFHA and floodway widths by letters from Ms. Beissel dated August 26 and December 8, 1998. The modifications are shown on the enclosed annotated copy of FIRM Panel(s) 0007 D, Profile Panel(s) 50P and 51P, and affected portions of the Floodway Data Table. This LOMR hereby revises the above-referenced panel(s) of the effective FIRM and the affected portions of the FIS report, both dated April 2, 1997. The modifications are effective as of the date shown above. The map panel(s) as listed above and as modified by this letter will be used for all flood insurance policies and renewals issued for your community .
