CHANGES ARE MADE IN DETERMINATIONS OF BASE FLOOD ELEVATIONS FOR THE
TOWN OF TELLURIDE AND THE UNINCORPORATED AREAS OF SAN MIGUEL COUNTY,
COLORADO, UNDER THE NATIONAL FLOOD INSURANCE PROGRAM

On September 30, 1992, the Department of Homeland Security's Federal Emergency Management
Agency identified Special Flood Hazard Areas (SFHAs) in the Town of Telluride and in the
unincorporated areas of San Miguel County, Colorado, through issuance of a Flood Insurance Rate Map
(FIRM). The Mitigation Division 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
these communities is appropriate. The modified Base Flood Elevations (BFEs) revise the FIRM for the
communities.

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 hydraulic analysis was performed to incorporate the effects of replacement of a bridge over the San
Miguel River and channel modifications from approximately 270 feet downstream of South Pine Street to
approximately 3,800 feet upstream of Maple Street. This has resulted in a revised delineation of the
regulatory floodway, increases and decreases in SFHA width, and increased decreased BFEs for the San
Miguel River. 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 determination to modify the BFEs may itselfbe changed.
