(a) The FP FLOODPLAIN AND FLOODWAY DISTRICTS are hereby established as "overlay" districts, meaning that these districts are overlaid upon other districts and the land so encumbered may be used in a manner permitted in the underlying district only to the extent such use is also permitted in the applicable overlay district. The FP Floodplain and Floodway District is intended for those areas adjoining any waterway which have been or may be expected hereafter to be covered by flood water, as determined by historical and technical studies. The FP Floodplain and Floodway District is created to protect the public health and safety, and to reduce the financial burdens which may be imposed on the community as a result of the improper use of lands having excessively high water tables or which are subject to periodic flooding.
(b) Performance Standards for Existing Uses.
(1) Maintenance and repair work may be accomplished that will protect the existing structure and will not create additional flood hazard on the premises.
(2) Subject to established height restrictions in the zone district, additions may be constructed to existing buildings if the new addition foundation top is one foot above the flood plain elevation.
(3) New additions not greater than 10% of the existing floor area may be constructed at the same elevation as the existing foundation structure if the new addition will not add to the flood hazard on the premises.
(c) Flood Plain and Floodway District Conditional Uses.
(1) New buildings or major additions to existing buildings shall be constructed with the lowest floor elevation three feet above flood height. Basements shall not be approved with openings below the flood height elevation.
(2) Any structures permitted shall be so located as to offer minimum obstruction to the flow of water.
(3) Filling and re-grading land shall be permitted if the proposed filling and grading is approved by the Ohio Department of Natural Resources and/or any other governmental agency having jurisdiction.
(4) All developments shall have engineered plans and procedures and demonstrate proper plats.
(5) Applications for a flood plain conditional use permit shall be filed with the Zoning Administrator containing the following information:
A. A survey by an Ohio registered land surveyor of the zoning lot proposed for use, including the entire area proposed to be used for the development.
B. A site plan indicating the arrangement and location of each building on the premises. The site plan shall also include a topographic survey having contour lines shown on a five foot interval.
C. The flood plain development requests shall be examined and evaluated by the Planning Commission in the terms of conformance with the regulations stated herein, and may recommend approval only after a determination has been made that the proposed development complies with the regulation of this Planning and Zoning Code.
