The flood that has a 1% chance of being equaled orexceeded in any given year. Base Flood Elevation (BFE)o The water surface elevation of the 1% annual chance flood.Attributes: FLD_ZONEo Flood zone designation used by County to designate a Special Flood Hazard Area (SFHA).o Zones: ASpecial Flood Hazard Area (SFHA) subject to inundation by the 1% annual chanceflood event.
