This index provides a list of all streets shown on the Flood
Insurance Rate Map (FIRM) that are partially or totally within
Special Flood Hazard Areas (SFHAs). This index should not be
used as an authoritative source for determining whether
specific streets, properties, or buildings are within an SFHA.
This index is intended to be used only as a guide for determining
the relative location of the street in question on the FIRM panel.

SPECIAL FLOOD HAZARD AREAS INUNDATED
BY 100 -YEAR FLOOD
ZONE A No base flood elevations determined.
ZONE AE Base flood elevations determined.
ZONE AH Flood depths of 1 to 3 feet (usually areas of
ponding); base flood elevations determined.
ZONEAO Flood depths of 1 to 3 feet (usually sheet flow
n sloping terrain); average depths deter-
mined. For areas of alluvial fan flooding;
velocities alsodetermined:
ZONE A99 To be protected from 100 -year flood by
Federal flood protection system under con-
struction; no base flood elevations deter-
mined.
ZONE V Coastal flood with velocity hazard (wave
action); no base flood elevations determined.
ZONE VE Coastal flood with velocity hazard (wave
action); base flood elevations determined.

OTHER FLOOD AREAS
ZONE X Areas of 500 -year flood; areas of 100 -year
flood with average depths of less than 1 foot or
with drainage areas less than 1 square mile;
and areas protected by levees from 100 -year
flood.
OTHER AREAS

mined.

NOTES
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 possible
updated flood hazard information prior to use of this map for property purchase
or construction purposes.
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.
Areas of special flood hazard (100 -year flood) include Zones A, AE, AH, AO, A99,
V, and VE.
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.
Floodway widths in some areas may be too narrow to show to scale. Floodway
widths are provided in the Flo6d insurance Study Report.
