§ 152.021 APPLICABILITY.

   Where Floodway and Flood Fringe Districts are delineated on the flood plain maps, the standards in §§ 152.040 et seq. will apply, depending on the location of a property. Locations where Floodway and Flood Fringe Districts are not delineated on the flood plain maps are considered to fall within the General Flood Plain District. Within the General Flood Plain District, the Floodway District standards in §§ 152.040-152.043 apply unless the floodway boundary is determined, according to the process outlined in § 152.061. In no cases shall flood plain development adversely affect the efficiency or unduly restrict or reduce the capacity of the channels of floodways of any tributaries to the main stream, drainage ditches, or any other drainage facilities or systems.

REQUIREMENTS FOR ALL FLOOD PLAIN DISTRICTS

§ 152.030 MINIMUM DEVELOPMENT STANDARDS.

   All new construction and substantial improvements must be:

   (A)   Designed (or modified) and adequately anchored to prevent floatation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy;

   (B)   Constructed with materials and utility equipment resistant to flood damage;

   (C)   Constructed by methods and practices that minimize flood damage; and

   (D)   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.

(Ord. 481, passed 2-16-2021)

§ 152.031 FLOOD CAPACITY.

   Flood plain developments must not adversely affect the hydraulic capacity of the channel and adjoining flood plain of any tributary watercourse or drainage system.

(Ord. 481, passed 2-16-2021)

§ 152.032 STORAGE AND PROCESSING OF MATERIALS.

   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.

(Ord. 481, passed 2-16-2021)

§ 152.033 CRITICAL FACILITIES.

   Critical facilities, as defined in § 152.015, are to be located, so that the lowest floor is not less than two (2) feet above the regional flood elevation, or the five hundred (500)-year flood elevation, whichever is higher.
