Special flood hazard areas for Oahu. These areas are from 2014. These data are the regulatory flood zones designated by FEMA and used for insurance rating purposes. Special flood hazard areas are subject to inundation by the 1% annual chance flood. The 1% annual chance flood (100-year flood), also known as the base flood, is the flood that has a 1% chance of being equaled or exceeded in any given year. The special flood hazard area is the area subject to flooding by the 1% annual flood. Areas of special flood hazard include Zones A, AE, AH, AO, AR, A99, D, V, VE, and X. The Base Flood Elevation (BFE) is the water-surface elevation of the 1% annual chance flood. Mandatory flood insurance purchase applies in these zones.
