The provisions for this district shall apply to all floodplains,
including A, AE, AO or AH Zones, for which flood profiles are not
available or where flood profiles are available but floodways have
not been delineated. Floodway and flood-fringe districts shall be
delineated when adequate data is available.
Pursuant to §
300-33, it shall be determined whether the proposed use is located within a floodway or flood-fringe area. Those uses permitted in floodway (§
300-24) and flood-fringe (§
300-28) districts are allowed within the General Floodplain District, according to the standards of §
300-32, provided that all permits or certificates required under §
300-38 have been issued.
Upon receiving an application for development within the General
Floodplain District, the County Land Use Planning and Zoning Department
shall:
A. Require the applicant to submit two copies of an aerial photograph
or a plan which shows the proposed development with respect to the
General Floodplain District limits, stream channel, and existing floodplain
developments, along with a legal description of the property, fill
limits and elevations, building floor elevations and floodproofing
measures, and the flood zone shown on the FIRM.
B. Require the applicant to furnish any of the following information
deemed necessary by the Wisconsin Department of Natural Resources
to evaluate the effects of the proposal upon flood height and flood
flows, regional flood elevation and to determine floodway boundaries:
(1) A hydrologic and hydraulic study as specified in §
300-38B(3).
(2) A plan (surface view) showing elevations or contours of the ground;
pertinent structure, fill or storage elevations; the size, location
and layout of all proposed and existing structures on the site; the
location and elevations of streets, the water supply, and sanitary
facilities; soil types; and other pertinent information.
(3) A profile showing the slope of the bottom of the channel or flow
line of the stream.
(4) Specifications for building construction and materials, floodproofing,
filling, dredging, channel improvement, storage, water supply and
sanitary facilities.
C. Transmit one copy of the information described in Subsections
A and
B above to the Wisconsin Department of Natural Resources regional office, along with a written request for technical assistance to establish regional flood elevations and, where applicable, floodway data. Where the provisions of §
300-38B(3) apply, the applicant shall provide all required information and computations to delineate floodway boundaries and the effects of the project on flood elevations.
