NOTES LEROY STREET 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 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 (1 OO-year flood) include Zones A, AE, A 1. A30, AH, AO, A99, V, VE and V1-V30. Certain areas not in Special Flood Hazard Areas may be protected by flood control structures. _J ZONE X UJ > a:: ,a Boundaries of the f100dways 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. FIOO<twaywidths in some ,areas may be too narrow to show to sc~le. Refer to Floodway Data Table where floodway width is shown at 1/20 lOch. Coastal base flood elevations apply only landward of 0.0 NGVD, and include the effects of wave action; these elevations may also diff~r 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 officials to determine if corporate limits have changed subsequent to the issuance of this map. For adjoining panels, see separately printed Map Index.
