CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE CITY
OF STEAMBOAT SPRINGS, ROUTT COUNTY, COLORADO, UNDER THE NATIONAL FLOOD
INSURANCE PROGRAM

On April 19, 1983, the Department of Homeland Security's Federal Emergency Management Agency
identified Special Flood Hazard Areas (SFHAs) in the City of Steamboat Springs, Routt County,
Colorado, through issuance of a Flood Insurance Rate Map (FIRM). The Mitigation Division has
detennined 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 this community is appropriate. The
modified Base Flood Elevations (BFEs) revise the 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 U.S.C.
4001-4128, and 44 CFR Part 65.

A revised hydraulic analysis was performed to incorporate new topographic information for Burgess
Creek, an existing box culvert underneath the ski area, and an existing control structure at the downstream
end of the twin box culverts at Ski Times Square Drive. This has resulted in a revised delineation of the
regulatory floodway, increases and decreases in SFHA width, and increased and decreased BFEs for
Burgess Creek from approximately 300 feet upstream of Ski Trail Lane to approximately 500 feet
upstream of Ski Times Square Drive. The table below indicates existing and modified BFEs for selected
locations along the affected lengths of the flooding source(s) cited above.

Under the above-mentioned Acts of 1968 and 1973, the Mitigation Division must develop criteria for
floodplain management. To participate in the National Flood Insurance Program (NFIP), the community
must use the modified BFEs to administer the floodplain management measures of the NFIP. These
modified BFEs 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
Division 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 Division's detennination to modify the BFEs may itself be changed.

Any person having knowledge or wishing to comment on these changes should immediately notify:

The Honorable Kathy Connell
City Council President
