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.

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. 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 16 Weld County Unincorporated Areas 080266 I -------- ZONE X udlsboro Ditch ZONE X 18 ZONE A ZONEAE ZONE AH 4462000m N ZONE AO No Base Rood Elevations determined.

FlOODWAY AREAS IN ZONE AE The floodway is the dlannel 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. tt OTHER FLOOD AREAS FEMA recommends that a Rood 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. ------- 23 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.
