1177.14 SPECIAL PROVISIONS APPLYING TO FLOODWAY PORTION OF REGIONAL FLOOD PLAIN DISTRICT.
(a) Permitted Uses. Uses permitted in Section 1177.13(a) are permitted uses.
(b) Special Exceptions. Other uses are allowed only as special exception uses within the floodway provided they comply with the provisions of this subsection, subsections (c), (d) and (e) hereof, and other standards established in this chapter, and any conditions attached by the Board to the issuance of special exception permits. No structure, temporary or permanent, fill including fill for roads and levees, deposit, obstruction, storage of materials or equipment, or other use shall be permitted which, acting alone or in combination with existing or reasonably anticipated uses, impairs the efficiency or the capacity of the floodway or unduly increases flood heights. Consideration of the effects of a proposed use shall be based on the assumption that wherever physically possible there will be an equal degree of encroachment extending for a significant reach on both sides of the stream. Special exception uses include:
(1) Uses or structures accessory to open space or special permit uses.
(2) Railroads, streets, bridges, utility transmission lines and pipelines.
(3) Storage yards for equipment, machinery or materials.
(4) Kennels and stables.
(c) Fill.
(1) Any fill or materials proposed to be deposited in the floodway will be allowed only upon issuance of a special exception. The fill or materials must be shown to have some beneficial purpose and the amount thereof not greater than is necessary to achieve that purpose, as demonstrated by a plan submitted by the owner showing the uses to which the filled land will be put and the final dimensions of the proposed fill or other materials.
(2) Such fill or other materials shall be protected against erosion by rip-rap, vegetative cover or bulkheading.
(d) Structures (Temporary or Permanent) Accessory to Special Permit Uses.
(1) Structures shall not be designed for human habitation.
(2) Structures shall have a low flood damage potential.
(3) The structure or structures, if permitted, shall be constructed and placed on the building site so as to offer the minimum obstruction to the flow of floodwaters.
A. Whenever possible, structures shall be constructed with the longitudinal axis parallel to the direction of flood flow, and
B. So far as practicable, structures shall be placed approximately on the same flood flow lines as those of adjoining structures.
(4) Structures shall be firmly anchored to prevent flotation which may result in damage to other structures, restriction of bridge openings and other narrow sections of the stream or river.
(5) Service facilities such as electrical and heating equipment shall ordinarily be constructed at or above the flood protection elevation for the particular area.
(6) Any new or improved water or sewer system shall be designed to minimize infiltration due to flooding and that any onsite waste disposal systems shall be designed to avoid impairment due to flooding.
(e) Storage of Material and Equipment.
(1) The storage or processing of materials that in time of flooding are buoyant, flammable, explosive or could be injurious to human, animal or plant life is prohibited.
(2) Storage of other material or equipment may be allowed upon issuance of special exceptions if not subject to major damage by floods and firmly anchored to prevent flotation or readily removable from the area within the time available after flood warning.
