§ 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.

§ 152.040 PERMITTED USES.

   The following uses, subject to the standards set forth in § 152.041, are permitted uses if otherwise allowed in the underlying zoning district or any applicable overlay district:

   (B)   Industrial and commercial loading areas, parking areas, streets, trails, airport landing strips, railroads, bridges, culverts, utility transmission lines and pipelines.

   (C)   Open space uses, including but not limited to private and public golf courses, tennis courts, driving ranges, archery ranges, picnic grounds, boat launching ramps, swimming areas, parks, wildlife and nature preserves, game farms, fish hatcheries, shooting preserves, hunting and fishing areas, and single or multiple purpose recreational trails.

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

§ 152.041 STANDARDS FOR FLOODWAY PERMITTED USES.

   (A)   The use must have a low flood damage potential.

   (B)   The use must not involve structures or obstruct flood flows. The use must not cause any increase in flood damages, nor any increase in flood elevations in areas where a floodway has been established, as certified by a registered professional engineer.

   (C)   Any facility that will be used by employees or the general public must be designed with a flood warning system that provides adequate time for evacuation if the area is inundated to a depth and velocity such that the depth (in feet) multiplied by the velocity (in feet per second) would exceed a product of four (4) upon occurrence of the regional one percent (1%) chance flood.

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

§ 152.042 CONDITIONAL USES.

   The following uses may be allowed as conditional uses following the standards and procedures set forth in § 152.113 of this chapter and further subject to the standards set forth in § 152.043, if otherwise allowed in the underlying zoning district.

   (A)   Structures accessory to primary uses listed in § 152.040(A) through (C) above and primary uses listed in § 152.042(B) through (C) below.

   (B)   Extraction, fill and storage of soil, sand, gravel, and other materials.

   (C)   Marinas, boat rentals, permanent docks, piers, wharves, water control structures, and navigational facilities.

   (D)   Storage yards for equipment, machinery, or materials.

   (E)   Fences that have the potential to obstruct flood flows.

   (F)   Levees or dikes intended to protect agricultural crops for a frequency flood event equal to or less than the ten (10)-year frequency flood event.
