§ 153.111 FLOOD PLAIN REGULATIONS.
   (A)   Zones. The flood plain shall be divided into two zones as follows:
      (1)   Restricted zone. The floodway necessary to preserve the natural capacity of the channel for flood water.
      (2)   Limited zone. The low-lying area on each side of the restricted zone where flooding is of sufficient frequency to require proofing of structures against flood loss.
   (B)   Zone boundaries. Zone boundaries shall be determined by the designated engineering personnel of the municipality and based upon the State of Ohio Department of Natural Resources publication, Floods at Columbus, Ohio, 1959, and other appropriate information.
   (C)   Change of zone boundary. The zone boundaries shall only be decreased subject to the provision of flood control or protection works and a finding by the designated engineering personnel of the municipality that such control or protection is adequate to prevent flooding of the land being removed from regulation under this section.
   (D)   Development standards. In addition to the provisions of the established zoning district, the following standards for arrangement and development of land and buildings are required under this section.
      (1)   Restricted zone. Within the restricted zone, the use and development of land shall be conducted in such a manner as not to fill the specified channel or to otherwise restrict the flow of flood waters and shall be subject to the approval of the designated engineering personnel of the municipality.
      (2)   Limited zone. Within the limited zone, the use shall be so developed as to proof the use or structure against flood damage by elevating above the prescribed level or other appropriate means and shall be subject to approval by the designated engineering personnel of the municipality.
