<br />
<br />Dear Mayor Berens:
<br />
<br />This responds to a request that the Federal Emergency Management Agency (FEMA) revise the effective
<br />Flood Insurance Rate Map (FlRM), Flood Boundary and Floodway Map (FBFM), and Flood Insurance Study
<br />(FlS) report for your community, in accordance with Part 65 of the National Flood Insurance Program (NFIP)
<br />regulations. In a letter dated January 6, 1997, Mr. Gary W. Behlen, P.E., City Engineer, City of Broomfield,
<br />requested that FEMA revise the FIRM, FBFM, and FIS report dated September 28, 1990, for the City of
<br />Broomfield, Colorado, to reflect updated topographic data and to incorporate the flood hazard information for
<br />Big Dry Creek from the PIS report dated May 17, 1993, for the City of Westminster, Colorado. This Letter
<br />of Map Revision (LOMR) will provide contiguous flood hazard information for the Cities of Westminster and
<br />Broomfield.
<br />
<br />All data required to complete our review of this request were submitted with letters from Mr. BeWen; Ms. Ann
<br />K. Woods, P.E., Carroll & Lange, Inc.; Mr. David W. Loseman, P.E., L.S., Senior Projects Engineer, City
<br />of Westminster; and Mr. Charles G. Swanson, P.E., City Engineer, City of Broomfield.
<br />
<br />We have completed our review of the submitted data and the flood data shown on the effective FIRM, FBFM,
<br />and FlS report. We have revised the FIRM, FBFM, and FlS report to modifY the elevations and the floodplain
<br />and floodway boundary delineations of the flood having a I-percent chance of being equaled or exceeded in
<br />any given year (base flood) along Big Dry Creek from approximately 7,230 feet upstream to approximately
<br />1,960 feet upstream of Zuni Street. As a result of the modifications, the base flood elevations (BFEs) for Big
<br />Dry Creek increased; the width of the Special Flood Hazard Area (SFHA), the area that would be inundated
<br />by the base flood, decreased; and the width of the regulatory floodway increased and decreased. The
<br />modifications are shown on the enclosed annotated copies of FIRM Panel(s) 0220 D, FBFM Panel(s) 0220,
<br />Profile Panel(s) 08P, and affected portions of the Summary of Discharges Table and Floodway Data Table.
<br />This LOMR hereby revises the above-referenced panel(s) of the effective FIRM, FBFM, and the affected
<br />portions of the FIS report, all dated September 28, 1990.
<br />
<br />Because this revision request also affects the City of Westminster, a separate LOMR for that community was
<br />issued on the same date as this LOMR.
<br />
<br />The modifications are effective as of the date shown above. The map panel(s) as listed above and as modified
<br />by this letter will be used for all flood insurance policies and renewals issued for your community.
