LEGENDSPECIAL FLOOD HAZARD AREAS (SFHAs) SUBJECT TOINUNDATION BY THE 1% ANNUAL CHANCE FLOOD

The 1% annual chance flood (100-year flood), also known as the base flood, is the floodthat has a 1% chance of being equaled or exceeded in any given year. The SpecialFlood Hazard Area is the area subject to flooding by the 1% annual chance flood. Areasof Special Flood Hazard include Zones A, AE, AH, AO, AR, A99, V and VE. The BaseFlood Elevation is the water-surface elevation of the 1% annual chance 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 FloodElevations determined.

ZONE AO Flood depths of 1 to 3 feet (usually sheet flow on sloping terrain);average depths determined. For areas of alluvial fan flooding, velocitiesalso determined.

ZONE AR Special Flood Hazard Area formerly protected from the 1% annualchance flood by a flood control system that was subsequentlydecertified. Zone AR indicates that the former flood control system isbeing restored to provide protection from the 1% annual chance orgreater flood.

ZONE A99 Area to be protected from 1% annual chance flood by a Federalflood protection system under construction; no Base Flood Elevationsdetermined.

ZONE V Coastal flood zone with velocity hazard (wave action); no Base FloodElevations determined.

ZONE VE Coastal flood zone with velocity hazard (wave action); Base FloodElevations determined.

FLOODWAY AREAS IN ZONE AE

The floodway is the channel of a stream plus any adjacent floodplain areas that must bekept free of encroachment so that the 1% annual chance flood can be carried withoutsubstantial increases in flood heights.

OTHER FLOOD AREAS

ZONE X Areas of 0.2% annual chance flood; areas of 1% annual chance floodwith average depths of less than 1 foot or with drainage areas less than1 square mile; and areas protected by levees from 1% annual chanceflood.

OTHER AREAS

ZONE X Areas determined to be outside the 0.2% annual chance floodplain.

ZONE D Areas in which flood hazards are undetermined, but possible.

COASTAL BARRIER RESOURCES SYSTEM (CBRS) AREAS

OTHERWISE PROTECTED AREAS (OPAs)

These BFEs are intended for flood insurancerating purposes only and should not be used as the sole source of floodelevation information.
