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

LEGEND

SPECIAL FLOOD HAZARD AREAS (SFHAs) SUBJECT TO INUNDATION

BY THE 10/0 ANNUAL CHANCE FLOOD

The 1 % annual chance flood (1 OO-year flood), also known as the base flood, is the flood that has a
1 % chance of being equaled or exceeded in any given year. The Special Flood Hazard Area is the
area subject to flooding by the 1 % annual chance flood. Areas of Special Flood Hazard include
Zones A, AE, AH, AO, AR, A99, V, and VE. The Base Flood Elevation is the water-surface elevation
of the 1 % annual chance flood.

No Base Rood Elevations determined.
Base Flood Elevations determined.
Flood depths of 1 to 3 feet (usually areas of ponding); Base Flood Elevations
determined.
Rood depths of 1 to 3 feet (usually sheet flow on sloping terrain); average
depths determined. For areas of alluvial fan flooding, velocities also determined.
Special Flood Hazard Areas formerly protected from the 1% annual chance
flood by a flood control system that was subsequently decertified. Zone AR
indicates that the former flood control system is being restored to provide
protection from the 1% annual chance or greater flood.
Area to be protected from 1% annual chance flood by a Federal flood protection
system under construction; no Base Flood Elevations determined.

To obtain more detailed information in areas where Base Flood Elevations (BFEs)
and/or floodways have been determined, users are encouraged to consult the Flood
Profiles and Floodway Data and/or Summary of Stillwater Elevations tables contained
within the Flood Insurance Study (FIS) Report that accompanies this FIRM. Users
should be aware that BFEs shown on the FIRM represent rounded whole-foot
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 Report should be utilized in conjunction with
the FIRM for purposes of construction and/or floodplain management.

Boundaries of the floodways were computed at cross sections and interpolated
between cross sections. The f100dways were based on hydraulic considerations with
regard to requirements of the National Flood Insurance Program. Floodway widths
and other pertinent f100dway data are provided in the Floodway Data table shown on
this FIRM.

FLOODWAY AREAS IN ZONE AE

4523OO0m N

The f100dway 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.

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 for this jurisdiction.

OTHER FLOOD AREAS

Areas of 0.2% annual chance flood; areas of 1% annual chance flood with
average depths of less than 1 foot or with drainage areas less than 1 square
mile; and areas protected by levees from 1 % annual chance flood.

OTHER AREAS

FEMA recommends that a Flood Insurance Policy be purchased for structures in
areas where levees are shown as providing protection from the 1 % annual chance
flood. Flooding is not covered by standard property/fire/dwelling insurance policies nor
is it covered by Homeowners Insurance, Renters Insurance, Condominium Owners
Insurance, or Commercial Property Insurance. Contact your insurance agent and local
floodplain administrator for further information.

ZONE A

ZONE X
ZONE D

Areas determined to be outside the 0.2% annual chance floodplain.
Areas in which flood hazards are undetermined, but possible.

Visit htto:/Iwww.fema.aov/odf/fhm/frm asah.odf for information on levees and the risk
of flooding in areas shown as being protected by levees.

The projection used in the preparation of this map was State Plane Colorado North
(feet). The horizontal datum was NAD 83, GRS80 spheroid. Differences in datum,
spheroid, projection or UTM zones used in the production of FIRMs for adjacent
jurisdictions may result in slight positional differences in map features across jurisdiction
boundaries. These differences do not affect the accuracy of this FIRM.

The profile baselines depicted on this map represent the hydraulic modeling baselines
that match the flood profiles in the Flood Insurance Study report. As a result of improved
topographic data, the profile baseline, in some cases, may deviate significantly from
the channel centerline or appear outside the Special Flood Hazard Area.
