[Ord. No. 2480, 5-8-2023]
A. No permit for development shall be granted for new construction,
substantial improvements and other improvements, including the placement
of manufactured homes within all numbered and unnumbered A Zones (including
AE, AO and AH Zones) unless the conditions of this Section are satisfied.
B. All areas identified as unnumbered A Zones on the FIRM are subject
to inundation of the 100-year flood; however, the water surface elevation
was not provided. The unnumbered A Zones shall be subject to all development
provisions of this Chapter. If Flood Insurance Study data is not available,
the community shall utilize any base flood elevation or floodway date
currently available from Federal, State or other sources.
C. New Construction, subdivision proposals, substantial improvements,
prefabricated buildings, placement of manufactured homes and other
developments shall require:
1.
Design or anchorage to prevent flotation, collapse or lateral
movement of the structure resulting from hydrodynamic and hydrostatic
loads, including the effects of buoyancy.
2.
New or replacement water supply systems and/or sanitary sewage
systems be designed to minimize or eliminate infiltration of floodwaters
into the systems and discharges from the systems into floodwaters,
and on-site waste disposal systems be located so as to avoid impairment
or contamination.
3.
Construction with materials resistant to flood damage, utilizing
methods and practices that minimize flood damages, and with electrical,
heating, ventilation, plumbing, and air conditioning equipment and
other service facilities that are designed and/or located so as to
prevent water from entering or accumulating within the components
during conditions of flooding.
4.
All utility and sanitary facilities be elevated or floodproofed
up to the regulatory flood protection elevation.
5.
That until a floodway has been designated, no development, including landfill, may be permitted within Zones A1-30 and AE on the City's FIRM unless the applicant for the land use has demonstrated that the proposed use, when combined with all other existing and reasonably anticipated uses, will not increase the water surface elevation of the 100-year flood more than one (1) foot on the average cross section of the reach in which the development or landfill is located as shown on the Flood Insurance Rate Study incorporated by reference: Section
405.020(C)(1) of this Chapter.
6.
Storage And Material And Equipment.
a.
The storage or processing of materials that are in time of flooding
buoyant, flammable, explosive, or could be injurious to human, animal
or plant life is prohibited.
b.
Storage of other material or equipment may be allowed if not
subject to major damage by floods and firmly anchored to prevent flotation
or if readily removable from the area within the time available after
flood warning.
7.
Subdivision proposals and other proposed new development, including
manufactured home parks or subdivision, be required to assure that:
(a) all such proposals are consistent with the need to minimize flood
damage; (b) all public utilities and facilities, such as sewer, gas,
electrical, and water systems are located, elevated and constructed
to minimize or eliminate flood damage; (c) adequate drainage is provided
so as to reduce exposure to flood hazards; and (d) proposals for development
(including proposals for manufactured home parks and subdivisions)
of five (5) acres or fifty (50) lots, whichever is lesser, include
within such proposals the regulatory flood elevation.
