(A) Permit required. A permit must be obtained from the Zoning Administrator to verify if a development meets all applicable standards outlined in this chapter prior to conducting the following activities:
(1) The erection, addition, modification, rehabilitation, or alteration of any building, structure, or portion thereof. Normal maintenance and repair also requires a permit if such work, separately or in conjunction with other planned work, constitutes a substantial improvement as defined in this chapter;
(2) The construction of a dam, on-site septic system, or any fence not meeting the definition of farm fence, as defined;
(3) The change or extension of a nonconforming use;
(4) The repair of a structure that has been damaged by flood, fire, tornado, or any other source;
(5) The placement of fill, excavation of materials, or the storage of materials or equipment within the floodplain;
(6) Relocation or alteration of a watercourse (including new or replacement culverts and bridges), unless a public waters work permit has been applied for; and
(7) Any other type of development as defined in this chapter.
(B) Minimum development standards. All new construction and substantial improvements must be:
(1) Designed (or modified) and adequately anchored to prevent flotation, collapse, or lateral
movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy;
(2) Constructed with materials and utility equipment resistant to flood damage;
(3) Constructed by methods and practices that minimize flood damage; and
(4) Constructed with electrical, heating, ventilation, ductwork, 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.
(C) Flood capacity. Floodplain developments must not adversely affect the hydraulic capacity of the channel and adjoining floodplain of any tributary watercourse or drainage system.
(D) The storage or processing of materials that are, in time of flooding, flammable, explosive, or potentially injurious to human, animal, or plant life is prohibited.
(E) Critical facilities, as defined, are to be located so that the lowest floor is not less than two feet above the regional flood elevation, or the 500-year flood elevation, whichever is higher.
