NOTES TO USERS LEGEND I SPECIAL FLOOD HAZARD AREAS SUBJECT TO INUNDATION BY THE 1 % ANNUAL CHANCE FLOOD EVENT 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. JOINS PANEL 0004 105003'45'" 40"03'45'" 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 Aood Hazard include Zones A, AE, AH. AQ, AR, A99, V. and VE. The Base Flood Elevation is the water surface elevation of the 1 % annual chance flood. 105"05'37.5" 40"03'45" . .." No base flood elevations determined. To obtain more detailed information in areas where Base Flood Elevation (BFEs) andlor floodways have been determined, users are encouraged to consult the Flood Profiles and Floodway Data tables contained within the Flood Insur- ance 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 should be utilized in conjunction with the FIRM for purposes of construction andlor floodplain management.

For areas of alluvial fan flooding, velocities also determined. , ,~ ", \' " Coastal Base Flood Elevation (BFEsl shown on this map apply only land- ward of 0.0' North American Vertical Datum (NAVD). Users of this FIRM should be aware that coastal flood elevations may also be provided in the Summary of Stillwater Elevations table in the Flood Insurance Study report for this community. Elevations shown in the Summary of Stillwater Elevations table should be used for construction, and lor floodplain management purposes when they are higher than the elevations shown on this FIRM. 10 ZONE AR Area of special flood hazard formerly protected from the 1 % annual chance flood event 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 event. . . I . . . . d.J , . ZONE A99 Area to be protected from 1 % flood protection system under determined. annual chance flood event by a Federal construction; no base flood elevations . ZONEV Coastal flood zone with velocity hazard (wave action): no base flood elevations determined. Boundaries of the floodways were computed at cross sections and interpolated between cross sections. The flood ways 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 Flood Insurance Study report for this jurisdiction. ZONE VE Coastal flood zone with velocity hazard (wave action); base flood elevations determined. FLOODWAY AREAS IN ZONE AE 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 in this jurisdiction. The flood way 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. .................. ......... ......... .................. ......... ......... OTHER FLOOD AREAS The projection used in the preparation of this map is Universal Tranverse Mercator (UTM) zone 13. The horizontal datum is NAD83, GRS 1980 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 the FIRM. Boulder And Weld County Ditch 4434000 M 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.
