Description: FEMA code for 100 year floodzones are
A = Area subject to 1% annual chance flood; no Base Flood Elevations determined
AE = Area subject to 1% annual chance flood; Base Flood Elevations determined
AH = Area subject to 1% annual chance flood with flood depths of 1 to 3 feet (usually areasof ponding); Base Flood Elevations determined
AO = Area subject to 1% annual chance flood with flood depths of 1 to 3 feet (usually sheet flow on sloping terrain); average depths determined
AR = The base floodplain that results from the decertification of a previously accredited flood protection system that is in the process of being restored to provide a 1% annual chance or greater level of flood protection
A99 = Area with a 1% annual chance of flooding that will be protected by a Federal flood control system where construction has reached specified legal requirements. No depths or Base Flood Elevations are shown within these zones
V = Area along coasts subject to inundation by the 1% annual chance flood event with additional hazards associated with storm-induced waves. Because detailed hydraulic analyses have not been performed, no Base Flood Elevations or flood depths are shown
VE = Coastal areas with a 1% annual chance or greater chance of flooding and an additional hazard associated with storm waves. Base Flood Elevations derived from detailed analyses are shown at selected intervals within these zones
100-IC (1 PCT ANNUAL CHANCE FLOOD DISCHARGE CONTAINED IN CHANNEL) = An area where the 1% annual chance flooding is contained within the channel banks and the channel is too narrow to show to scale. This definition was ascertained from the FEMA National Flood Insurance Program flood zone definitions.
