NOTES TO USERS

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.

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 fIoodways were based on hydraulic considerations with
regard to requirements of the National Flood Insurance Program. Floodway widths
and other pertinent fIoodway data are provided in the Floodway Data table shown on
this FIRM.

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.

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. Aooding is not covered by standard propertylfire/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.

VISit htq>:/Iwww.fema.gov/pdf/fhmffrm gsah.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.

Rood 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
http://www.nas.noaa.govor contact the National Geodetic Survey at the following

shown on this map, please contact the Information Services Branch of the National
Geodetic Survey at (301) 713- 3242, or visit its website at http://www.ngs.noaa.aov.

Base map information shown on this FIRM was provided by the Larimer County GIS
and Mapping Department. Additional input was provided by the City of Fort Collins
Geographic Information Service Division. These data are current as of 2005.

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.

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 of the panels on which each community
is located.

SPECIAL FLOOD HAZARD AREAS (SFHAs) SUBJECT TO INUNDATION

BY THE 10/0 ANNUAL CHANCE FLOOD

The 1% annual chance flood (100-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 Rood Elevation is the water-surface elevation
of the 1% annual chance flood.

No Base Rood Elevations determined.
Base Flood Elevations determined.
Rood depths of 1 to 3 feet (usually areas of ponding)j Base Rood Bevations
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 Rood Hazard Areas fonnerly 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 ftom 1% annual chance flood by a Federal flood protection
system under construction; no Base Rood Elevations determined.
