ZONE VE:
Areas subject to inundation by the 1-percent-annual-chance flood event
with additional hazards due to storm-induced velocity wave action. Base Flood
Elevations (BFEs) are derived from detailed hydraulic analyses. Mandatory flood
insurance purchase requirements and floodplain management standards apply.
ZONE AE:
Areas subject to inundation by the 1-percent-annual-chance flood event
determined by detailed methods. Base Flood Elevations are created. Mandatory
flood insurance purchase requirements and floodplain management standards
apply.
ZONE AH:
Areas subject to inundation by 1-percent-annual-chance shallow flooding
(usually areas of ponding) where average depths are between 1 and 3 feet. Base
Flood Elevations are derived from detailed hydraulic analyses for this zone. Mandatory
flood insurance purchase requirements and floodplain management standards
apply.
ZONE A:
Areas subject to inundation by the 1-percent-annual-chance flood event
and generally determined using approximate methodologies. Because detailed
hydraulic analyses have not been performed, no BFEs or flood depths are created.
Mandatory flood insurance purchase requirements and floodplain management
standards apply.
ZONE X500:
Zone X500 is a moderate flood hazard area and is an area between the
limits of the base flood and the 0.2-percent-annual-chance (or 500-year) flood.
Mandatory flood insurance is not required.
ZONE X:
Zone X is the flood insurance rate zone used for areas outside the
0.2-percent-annual-chance floodplain. This zone is outside of the 500-year
floodplain. No BFEs or depths are created for this zone and flood insurance is
not required.
