(a) Composition. The Floodway Fringe District shall include all those lands comprising the floodway fringe, as delineated on the Flood Insurance Rate Map. By definition, the Floodway Fringe District commences at the extreme edge of the Floodway District and extends laterally across the floodplain, encompassing the portion of the floodplain that could be completely obstructed without increasing the base flood water surface elevation by more than one foot at any point on the floodplain.
(b) Use Standards.
(1) The primary objective of regulations for land comprising the Floodway Fringe District is to protect both the structure and/or use from damage due to exposure to water wetting during periods of flood.
(2) The proposed development, use or activity shall not, if permitted, endanger the welfare or safety of the community during periods of flood.
(c) Permitted Uses. To the extent not otherwise prohibited by subdivision rules and regulations, the Building Code or other City regulations, any use permitted under Section 1149.11
(c) or by base zoning in any portion of a base zoning district included within the Floodway Fringe District shall be permitted in that portion of the Floodway Fringe District which includes such base zoning district.
(d) Fill. The deposit of acceptable fill materials shall be permitted within the Floodway Fringe District.
(1) Acceptable fill materials: soils, sands, stone, brick, concrete and reclaimed rubble from demolition projects consisting exclusively of these same materials.
(2) Unacceptable fill materials (organic): No organic materials such as tires, mattresses, garbage, offal, leaves, wood products, plastics, petroleum residues, etc., shall be deposited within this District.
(3) Unacceptable fill materials (inorganic): No metals, glass, pottery or other inorganic materials other than those permitted in paragraph (1) hereof shall be deposited within this District.
(e) Structures.
(1) Any new structure or substantial improvement erected within the Floodway Fringe District shall be so sited that the lowest floor, including basement floor, is at an elevation not less than the regulatory flood protection elevation.
(2) When fill is used to increase the elevation of a site on which a structure or substantial improvement is to be erected, such site shall be filled and compacted to an elevation not less than one foot below the regulatory flood protection elevation, and shall extend at such elevation for not less than fifteen feet beyond the external limits of any structure or substantial improvement erected thereon.
(3) Each habitable structure shall include at least one exit leading directly on to a walkway, driveway or roadway whose surface elevation is not less than the regulatory flood protection elevation, and such escape route shall lead directly out of the flood plain area.
(4) All new and substantially improved residential and nonresidential nonbasement structures which are elevated to the base flood elevation using pilings, columns, posts or solid foundation perimeter wall with openings sufficient to allow unimpeded movement of flood waters shall be known as "enclosures below lowest floor". Fully enclosed areas below the lowest floor that are usable solely for parking of vehicles, building access or storage in an area other than a basement and which are subject to flooding shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters. Designs for meeting this requirement must:
A. Be certified by a registered professional engineer or architect; or
B. Must meet or exceed the following criteria:
1. A minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding shall be provided.
2. The bottom of all openings shall be no higher than one foot above grade. Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of floodwaters.
(f) Manufactured Homes. A separate permit application shall be filed for each manufactured home or similar unit, regardless of proposed use, which is to be located in the Floodway Fringe District and is not subject to the manufactured home requirements of Ohio R.C. Chapter 3733. The permit application shall be reviewed by the Floodplain Administrator to assure compliance with the following provisions and criteria:
(1) A manufactured home may be located only on a site which has been filled and compacted to an elevation not less than the regulatory flood protection elevation.
(2) The area of the filled site for each manufactured home shall be not less than 4,000 square feet.
(3) The manufactured home shall not be located nearer than fifteen feet to any boundary of the site.
(4) Each manufactured home site shall have direct access to a walkway, driveway, or roadway whose surface elevation is not less than the regulatory flood protection elevation and such escape route shall lead directly out of the floodplain area.
(5) Over-the-top ties shall be provided at each of the four corners of the manufactured home, with two additional ties per side at intermediate locations for those units exceeding fifty feet in length. For units less than fifty feet in length, one additional tie shall be provided per side.
(6) Frame ties shall be provided at each corner of the manufactured home, with five additional ties per side at intermediate points for those units exceeding fifty feet in length. For units less than fifty feet in length, four additional ties shall be provided per side.
(7) All components of the anchoring system shall be capable of carrying a stress force of no less than 4,800 pounds.
(8) Any additions to the manufactured home shall be similarly anchored.
(9) Provisions shall be made for adequate surface drainage.
(10) Access shall be provided for a manufactured home hauler at an elevation not less than the regulatory flood protection elevation.
(11) Such standards shall also apply to all recreational vehicles that are either:
A. Located on sites for 180 days or more, or
B. Are not fully licensed and ready for highway use.
(g) Storage.
(1) There shall be no storage or processing of materials and/or substances that are, in the time of flooding, buoyant or which are flammable, explosive or which could be injurious to humans, animals, plant life or aquatic life at an elevation less than the regulatory flood protection elevation.
(2) Storage of nonbuoyant materials and/or equipment which are not subject to major damage by floods is permitted at elevations less than the regulatory flood protection elevation.
