<br />NOTES TO USERS
<br />
<br />This map is for use in administering the National Flood Insurance Program. It does
<br />not necessarily identify all areas subject to flooding, particularly from local drainage
<br />sources of small size. The community map repository should be consulted for
<br />possible updated or additional flood hazard information.
<br />
<br />To obtain more detailed information in areas where Base Flood Elevations (BFEs)
<br />and/or floodways have been determined, users are encouraged to consult the Flood
<br />Profiles and Floodway Data and/or Summary of Stillwater Elevations tables contained
<br />within the Flood Insurance Study (FIS) Report that accompanies this FIRM. Users
<br />should be aware that BFEs shown on the FIRM represent rounded whole-foot
<br />elevations. These BFEs are intended for flood insurance rating purposes only and
<br />should not be used as the sole source of flood elevation information. Accordingly,
<br />flood elevation data presented in the FIS Report should be utilized in conjunction with
<br />the FIRM for purposes of construction and/or floodplain management
<br />
<br />Boundaries of the floodways were computed at cross sections and interpolated
<br />between cross sections. The floodways were based on hydraulic considerations with
<br />regard to requirements of the National Flood Insurance Program. Floodway widths
<br />and other pertinent fIoodway data are provided in the Roodway Data table shown on
<br />this FIRM.
<br />
<br />Certain areas not in Special Flood Hazard Areas may be protected by flood control
<br />structures. Refer to Section 2.4 "Flood Protection Measures" of the Flood Insurance
<br />Study Report for information on flood control structures for this jurisdiction.
<br />
<br />FEMA recommends that a Rood Insurance Policy be purchased for structures in
<br />areas where levees are shown as providing protection from the 1% annual chance
<br />flood. Rooding is not covered by standard propertylfire/dwelling insurance policies nor
<br />is it covered by Homeowners Insurance, Renters Insurance, Condominium Owners
<br />Insurance, or Commercial Property Insurance. Contact your insurance agent and local
<br />floodplain administrator for further information.
<br />
<br />Visit http://www.fema.aov/pdflfhmlfrm 9sah.pdf for information on levees and the risk
<br />of flooding in areas shown as being protected by levees.
<br />
<br />The projection used in the preparation of this map was State Plane Colorado North
<br />(feet). The horizontal datum was NAD 83, GRS80 spheroid. Differences in datum,
<br />spheroid, projection or UTM zones used in the production of FIRMs for adjacent
<br />jurisdictions may result in slight positional differences in map features across jurisdiction
<br />boundaries. These differences do not affect the accuracy of this FIRM.
<br />
<br />Flood elevations on this map are referenced to the North American Vertical Datum of
<br />1988. These flood elevations must be compared to structure and ground elevations
<br />referenced to the same vertical datum. For information regarding conversion
<br />between the National Geodetic Vertical Datum of 1929 and the North American
<br />Vertical Datum of 1988, visit the National Geodetic Survey website at
<br />http://www.nas.noaa.aov or contact the National Geodetic Survey at the following

<br />Base map information shown on this FIRM was provided by the Larimer County GIS
<br />and Mapping Department. Additional input was provided by the City of Fort Collins
<br />Geographic Information Service Division. These data are current as of 2005.
<br />
<br />The profile baselines depicted on this map represent the hydraulic modeling baselines
<br />that match the flood profiles in the Flood Insurance Study report. As a result of improved
<br />topographic data, the profile baseline, in some cases, may deviate significantly from
<br />the channel centerline or appear outside the Special Flood Hazard Area.
<br />
<br />Corporate limits shown on this map are based on the best data available at the time
<br />of publication. Because changes due to annexations or de-annexations may have
<br />occurred after this map was published, map users should contact appropriate
<br />community offICials to verify current corporate limit locations.

<br />dates for each community as well as a listing of the panels on which each community
<br />is located.

<br />SPECIAL FLOOD HAZARD AREAS (SFHAs) SUBJECT TO INUNDATION
<br />BY THE 10/0 ANNUAL CHANCE flOOD
<br />The 1% annual chance flood (100-yearflood), also known as the base flood, is the flood that has a
<br />1% chance of being equaled or exceeded in any given year. The Special Flood Hazard Area is the
<br />area subject to flooding by the 1% annual chance flood. Areas of Special Flood Hazard include
<br />Zones A. AE. AH. AO, AR. A99, V, and VE. The Base Rood Elevation is the water-surface elevation
<br />of the 1% annual chance flood.
