B Zone, NFIP
B Zone, NFIP :
B Zone is defined as an area of moderate flood hazard, usually depicted on Flood Insurance Rate Maps as between the limits of the base flood and 500-year flood of the primary source of flooding. B Zones may have local, shallow flooding problems. B Zones are also used to designate areas protected by levees and base floodplains of little hazard, such as those with average flood depths of less than 1 foot.
