(3) ESTABLISHMENT OF FLOODPLAIN ZONING DISTRICTS
The flood hazard areas regulated by this ordinance are divided into districts as follows:
a) The Floodway District (FW), is the channel of a river or stream and those portions of the
floodplain adjoining the channel required to carry the regional floodwaters, within AE Zones
as shown on the FIRM, or within A Zones shown on the FIRM when determined according
to s. 5.1(5).
b) The Floodfringe District (FF) is that portion of a riverine special flood hazard area outside
the floodway within AE Zones on the FIRM, or, when floodway limits have been determined
according to s. 5.1(5), within A Zones shown on the FIRM.
c) The General Floodplain District (GFP) is those riverine areas that may be covered by
floodwater dur

boundary shall be determined by the map scale.
(5) REMOVAL OF LANDS FROM FLOODPLAIN
a) Compliance with the provisions of this ordinance shall not be grounds for removing land from
the floodplain unless it is filled at least two feet above the regional or base flood elevation, the
fill is contiguous to land outside the floodplain, and the map is amended pursuant to s. 8.0
Amendments.

b) The delineation of any of the Floodplain Districts may be revised by the community where
natural or man-made changes have occurred and/or where more detailed studies have been
conducted. However, prior to any such change, approval must be obtained from the
Wisconsin Department of Natural Resources and Federal Emergency Management Agency.
A completed Letter of Map Revision is a record of this approval. The floodplain administrator
shall not sign a community acknowledgement form unless all criteria set forth in the following
paragraphs are met:
1. The land and/or land around the structure must be filled at least two feet above the
regional or base flood elevation;
2. The fill must be contiguous to land outside the floodplain; Applicant shall obtain floodplain

A more restrictive ordinance shall continue in full force and effect to the extent of the greater

pable of resisting hydrostatic and hydrodynamic loads and effects of
buoyancy:
i. Where a non-residential structure is intended to be made watertight below the
base flood elevation, a registered professional engineer or architect must
develop and/or review structural design, specifications, and plans for the
construction, and must certify that the design and methods of construction are in

accordance with accepted standards of practice for meeting the provisions of s.
6.1(4)(g) above.
ii. The community must maintain a record of such certification including the specific

h) Fully enclosed areas below the lowest floor of repair or reconstruction of nonconforming
structures and substantial improvements in zones A1-30, AE, and AH that are usable solely
for parking of vehicles, building access, or storage, must be designed to adequately equalize
hydrostatic forces on exterior walls by allowing for the entry and exit of floodwaters.
Subsequent improvements to repaired or reconstructed nonconforming structures must not
increase the degree of their nonconformity. Designs for meeting this requirement must
