The Floodplain Overlay District is divided into four districts
as follows:
A. The Floodway District includes the channel of a river or stream and
those portions of the floodplain adjoining the channel required to
carry the regional floodwaters and are contained within AE Zones as
shown on the Flood Insurance Rate Maps.
B. The Floodfringe District includes that portion between the regional
flood limits and the floodway and displayed as AE Zones on the Flood
Insurance Rate Maps.
C. The General Floodplain District includes those areas that may be
covered by floodwater during the regional flood and does not have
a base flood elevation or floodway boundary determined, including
A, AH, and AO Zones on the Flood Insurance Rate Maps.
D. The Flood Storage District is that area of the floodplain where storage
of floodwaters is calculated to reduce the regional flood discharge.
Compliance with the provisions of this division shall not be grounds for removing land from the floodplain unless 1) it is filled at least two feet above the regional flood elevation or base flood elevation, 2) the fill is contiguous to land outside of the floodplain, and 3) the map is amended pursuant to §
170.1271.
