1 Elevatioo Reference Marks (ERM) elevations listed on this map were obtained and/or devek>ped to establish vertical control for determination of flood elevations and Uoo~lain boundaries portrayed on this map, Users should be aware thaI these ERM elevations may have changed since the publication of this map. To obtain up-to-date-elevatiOl1 information on National Geodetic Survey (NGS) ERMs shown on this im~lon ServIces Branch 01 the NGS at (301) Of ~ !heir website at www.ngs,noa,a.gov. Map users should seek verification of non-NGS ERM monument elevations when using these elevations for construction or floodplain management purposes, To obtain more detaHed infonnation In areas where Base FlOOd Elevations (BFEs) and/or floodways have been determined. users are encouraged to the Flood Profiles and Floodway Data tables contained within the Flood Insurance Study (FIS) report that a~ this Usefs should be ~ware that 8FEs shown on the FIRM represent roonoea whole-foot ~Iavations and therefore may not exactly reflect Ihe flood elevation data presented in the FIS. For construction and/or f~lain management purposes, users are encouraged to use the flood elevation data presented in this FIS in conjunction with the data shown on the FIRM. ~ Fremont County Coastal BFE's shown on this map apply only landYIard of 0,0' National Geodetic Vertical Datum (NGVD).

The community map repository should be consulted for more detailed data on BFEs, and for any information on floodway delineations, prior to use of this map for property purchase or construction purposes, Areas of Special Flood Hazard (100-year flood) include Zones A, AE, A1- AH, AO, A99, V, VE and Vl-V30. Certaln areas not in Special Flood Hazard Areas may be protected by flood control structures. 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 Federal Emergency Management Agency, FloodINaywidths in some ,areas may be too narrow to show to scale. Refer to Floodway Data Table where f100dway width is shown at 1/20 inch, Corporate limits shown are current as of the date of this map, The user should contact appropriate community officials to determine if corporate limits have changed subsequent to the issuance of this map.
