This map is for use in administering the National flood Insurance Program. It
cloes not necessarily identify aU areas subject to flooding, particularly from local
drainage sources of small size. The community map repository should be
consulted tor possible updated or additional flood hazard information.

To obtain more detailed information in areas where Bas:& FJood Elevation
(BFEs) andlor floodways have been determined, users are encouraged to consult
the Flood Profiles and Floodway Data tables contained within the Flood Insur-
ance Study (FIS) report that accompanies this RRM. Users should he aware that
BFEs shown on the FIRM represent rounded whole-toot :elevations. These BFEs
are intended for flood insurance rating purposes only and should not be used
as the sole source of flood elevation information. Accordingly, flood elevation
data presented in the FIS should be utilized in conjunction with the RRM for
purposes of construction and/or floodplain management.

CoastaJ Base Rood Elevation (BFEs) shown on this map apply only land-
ward of 0.0' North American Vertical Datum (NAVD). Users of this FIRM
should be aware that coastal flood elevations may also be provided in the
Summary of Stillwater Elevations table in the Flood Insurance Study report for
this community. Elevations shown in the Summary of Stillwater Elevations table
should be used for construction, and/or floodplain management purposes when
they are higher than the elevations shown on this RRM.

Boundaries of the floodways were computed at cross sections and interpolated
between cross sections. The floodways were based on hydraulic considerations
with regard to requirements of the National Flood Insurance Program. Floodway
widths and other pertinent floodway data are provided in the Flood Insurance
Study report for this jurisdiction.

Certain areas not in Special Flood Hazard Areas may be protected by flood
control structures. Refer to Section 2.4 "Flood Protection Measures" of
the Flood Insurance Study report for information on flood control structures
in this jurisdiction.

The prqecdon used in the preparation of this map is Universal Tranverse
Mercator (UTM) zone 13. The homontaldamm is NAD83,GRS1980
spheroid. Differences in datum, spheroid, projection or UTM zones used in
the production of FIRMs Tor adjacent jurisdictions may result in slight pOSitional
differences in map features across jurisdiction boundaries. These differences
do not affect the accuracy of the FIRM.

Flood elevations on this map are referenced to the North American Vertical
Datum of 1988. These flood elevations must be compared to structure and
ground elevations referenced to the same vertical datum. for information
regarding conversion between the National Geodetic Vertical Datum of 1929
and the North American Vertical Datum of 1988, visit the National Geodetic
Survey website at www.ngs.noaa.gov or contact the Nationsl Geodetic Survey

Base map information shown on this FIRM was provided in digital format by
Routt County GIS Department.

Corporate limits shown on this map are based on the best data available
at the time of publication. Because changes due to annexations or de-annexations
may have occurred after this map was published, map users should contact
appropriate community officials to verify current corporate limit locations.

dates for each community as well as a listing 01 the panels on which each
community is located.

This map reflects more detailed and up-to-date stream channel configurations
than those shown on the previous FIRM for this jurisdiction. The floodplains
and floodways that were transferred from the previous FIRM may have been
adjusted to conform to these new stream channel configurations. As a
result, the Flood Profiles and Rocdway Data tables in the Flood Insurance
Study report may reflect stream channel distances that differ from what is
shown on this map.

SPECIAL FLOOD HAZARD AREAS SUBJECT TO lNUNDA T10N
BY THE 1 % ANNUAL CHANCE FLOOD EVENT

The 1 % annual chance flood (100-year flood), alse known as the base flood, is the fleod
that has a 1 % chance of being equaled or exceeded in any given year. The Special
Flood Ha2ard Area is the area subject to flooding by the 1 % annual chance flood. Areas
of Special Flood Ha2srd include Zones A, AE, AH, AO, AR, ASS, V, and VI:. The Base
Flood Elevation is the water surface elevation of the 1 % annual chance flood.

No base flood elevations determined.

Flood depths of 1 to 3 feat (usuaUy sheet flow on sloping terrain);
average depths determined. For areas of alJuvial fan flooding, velocities
alse determined.

Area of special flood na2srd formerly protected from the 1 % annual
chance flood event by a flood control system that was subsequently
decertified. Zone AR indicates that the former fleod control system is
being restored to provide protection from the 1 % annual chance or
greater flood event.

Area to be protected from 1 % annual chance flood avent by a Federal
flood protection system under construction; no base flood elevations
determined.

Coastal flood zone with velocity ha2ard{wave action); no base flood
elevations determined.

Coastel flood zone with velocity na2srd (wave action); base flood elevations
determined.

FLOODW A Y AREAS IN ZONE AE

The floodway is the channel of a stream plus any adjacent floodplain areas that must be
kept free of encroachment so that the 1 % annual chance flood can be carried without
substantial increases in flood heights.
