NOTES TO USERS LEGEND 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. 307000 FT 1 050 15' 00" 400 45' 00" 3075000 FT 3080000 FT 3085000 FT 3090000 FT 3095000 FT 3100000 FT 16 15 18 1050 07' 30" 400 45' 00" SPECIAL FLOOD HAZARD AREAS (SFHAs) SUBJECT TO INUNDATION BY THE 10/0 ANNUAL CHANCE FLOOD 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 FI RM 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. 1515000 FT North Fork Cache La Poudre River + 13 o <( o 0::: w (!) o ii 0::: w a..

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. LL0532 16 ZONE A ZONE AE ZONE AH No Base Rood Elevations determined. Base Flood Elevations determined. Flood depths of 1 to 3 feet (usually areas of ponding); Base Flood Elevations determined. Flood 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. Larimer County Unincorporated Areas 080101 ZONE AO 451 OooOm N ZONE AR 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 Floodway Data table shown on this FIRM. ZONE X Q./ ~~ ~f ~Q ~~ ~~~ ZONE A99 ZONE X FLOODWAY AREAS IN ZONE AE 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. 1510000 FT 19 + - 4509oo0m N OTHER FLOOD AREAS ZONE X 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. 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 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. OTHER AREAS ZONE X ZONE 0 Areas determined to be outside the 0.2% annual chance floodplain.
