Users should be aware that BFEs shown on the FIRM represent rounded whole-foot elevations and therefore may not exactly reflect the flood elevation data presented in the FIS. For construction and/or floodplain management purposes, users are encouraged to use the flood elevation data presented in this FIS in conjunction with the data shown on the FIRM. ......I' Elevation Reference Marks (ERM) elevations listed on this map were obtained and/or developed to establish verticai control for determination of flood elevations and floodplain boundaries portrayed on this map. Users should be aware that these ERM elevations may have changed since the publication of this map. To obtain up-to-date-elevation information on National Geodetic Survey (NGS) ERMs shown on this map, please contact the Information Services Branch of the NGS at (301) 713-3242, or w-it their website at www.ngs.noaa.gov. Map users should seek verification of non-NGS ERM monument elevations wher. using these elevations for construction or floodplain management purposes. Coastal BFE's shown on this map apply only landward of 0.0' National Geodetic Vertical Datum (NGVD). Users of this FIRM should be aware that coastal flood elevations are also 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/or floodplain management purposes when they are higher than the elevCltions shown on this FIRM. lJ o v, -1 )> ::0 o )> o X SPECIAL FLOOD HAZARD AREAS INUNDATED BY 100- YEAR FLOOD ZONE A No base flood elevations determined.

The community map repository should be consulted for more detailed data on BFEs, and for any information on Hoodway 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- A30, AH, AO, A99, V, VE and V1-V30. Certain 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. Floodwaywidths in some,areas may be too narrow to show to scale. ,Refer to Floodway Data Table where floodway 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.
