A. A floodplain development permit is required for a person to establish, alter, or substantially improve an artificial obstruction, nonconforming use or development within the regulated flood hazard area.
B. A floodplain development permit is required for artificial obstructions, developments, and uses not specifically listed in sections 14-5-5 and 14-5-6 of this chapter, except as allowed without a floodplain development permit in section 14-5-4 of this chapter, or as prohibited as specified in section 14-5-3 of this chapter, within the regulated flood hazard area.
C. Artificial obstructions and nonconforming uses in regulated flood hazard area not exempt under section 14-5-4 of this chapter are public nuisances unless a floodplain development permit has been obtained.
D. A floodplain development permit is required for an alteration of an existing artificial obstruction or nonconforming use that increases the external size or increases its potential flood hazard and not exempt under section 14-5-4 of this chapter.
E. A floodplain development permit is required to reconstruct or repair an existing artificial obstruction that has experienced substantial damage and will undergo substantial improvement.
F. Maintenance of an existing artificial obstruction or use that is a substantial improvement or an alteration requires a floodplain development permit.
G. In all regulated flood hazard areas the following provisions are required for all new construction and substantial improvements:
1. All new construction or substantial improvements shall be 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. All new construction or substantial improvements shall be constructed by methods and practices that minimize flood damage;
3. All new construction or substantial improvements shall be constructed with materials resistant to flood damage;
4. All new construction or substantial improvements shall be constructed 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;
5. All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the system;
6. New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of floodwaters into the system and discharge from the systems into floodwaters; and
7. On site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding. (Ord. 15-16, 10-5-2015)
