The 1% annual chance flood (100-year flood), also known as the base flood, is the flood that hasa 1% chance of being equaled or exceeded in any given year. The Special Flood Hazard Area isthe area subject to flooding by the 1% annual chance flood. Areas of Special Flood Hazardinclude Zones A, AE, AH, AO, AR, A99, V, and VE. The Base Flood Elevation is the water-surfaceelevation of the 1% annual chance flood.
No Base Flood Elevations determined.Base Flood Elevations determined.Flood depths of 1 to 3 feet (usually areas of ponding); Base Flood Elevationsdetermined.Flood depths of 1 to 3 feet (usually sheet flow on sloping terrain); averagedepths determined. For areas of alluvial fan flooding, velocities also determined.
Special Flood Hazard Areas formerly protected from the 1% annual chanceflood by a flood control system that was subsequently decertified. ZoneAR indicates that the former flood control system is being restored to provideprotection from the 1% annual chance or greater flood.Area to be protected from 1% annual chance flood by a Federal floodprotection system under construction; no Base Flood Elevations determined.Coastal flood zone with velocity hazard (wave action); no Base Flood Elevationsdetermined.Coastal flood zone with velocity hazard (wave action); Base Flood Elevationsdetermined.
The floodway is the channel of a stream plus any adjacent floodplain areas that must be kept free ofencroachment so that the 1% annual chance flood can be carried without substantial increases inflood heights.
Areas of 0.2% annual chance flood; areas of 1% annual chance flood withaverage depths of less than 1 foot or with drainage areas less than 1 squaremile; and areas protected by levees from 1% annual chance flood.
Areas determined to be outside the 0.2% annual chance floodplain.Areas in which flood hazards are undetermined, but possible.
CBRS areas and OPAs are normally located within or adjacent to Special Flood Hazard Areas.
