Areas of 100-year shallow flooding where depths are between one (1) and three (3) feet; average depths of inundation are shown, but no flood hazard factors are determined. Areas of 100-year shallow flooding where depths are between one (1) and three (3) feet; base flood elevations are shown, but no flood hazard factors are determined. AO AH A 1-A30 Areas of WO-year flood; base flood elevations and flood hazard factors determined. A99 Areas of 100-year flood to be protected by flood protection system under construction; base flood elevations and flood hazard factors not determined. B Areas between limits of the 100-year flood and SOO-year flood; or certain areas subject to 100-year flooding with average depths less than one (1) foot or where the contributing area is.less than one square mile; or areas protected by levees the base flood. (Medium shading) C Areas of minimal flooding. (No shading) o Areas of undetermined, but possible, flood hazards. V Areas of 100-year ~oastal flood with velocity (wave action); base flood elevations and flood hazard factors not determined. V1-V30 Areas of 100-year coastal flood with velocity (wave action); base flood elevations and flood hazard factor; determined. NOTES TO USER 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, or all planimetric features outside Special Flood Hazard Areas. The commtlIlity map repos~tory sho.uld be consulted for more detailed data on BFEs, and for any mformatlon on floodway delineations, prior to use of this map for property purchase or construction purposes. Areas of special flood hazard (1 oo-year flood) include Zones A, A 1-30, AE, AH, AO, A99, V, V1-30 and VE. Certain areas not in Special Flood Hazard Areas may be protected by flood control structures. Coastal base flood elevations apply only landward of 0.0 NGVD, and include the effects of wave action; these elevations may also differ significantly from those developed by the National Weather Service for hurricane evacuation planning. Corporate limits shown are current as of the date of this map. The user should contact appropriate community offidals to determine if corporate limits have changed subsequent to the issuance of this map. For adjoining map panels see separately printed Map Index.
