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 FloodH~zard Areas... The. community map repository shovld.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. A1-30, 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 officials to determine if corporate
limits have changed subsequent to the issuance of this map.

For adjoining map panels see separately printed Map Index.
