(a) Composition. The Floodway District shall include all those lands comprising the floodway, as delineated on the Flood Insurance Rate Map. By definition, the floodway includes the channel of a stream, plus any adjacent floodplain areas that must be kept free of encroachment, in order that the 100 year flood may be discharged without substantially increasing the base flood water surface elevation at any point in the floodplain or contributing to hazardous flow velocities.
(b) Use Standards.
(1) Lands comprising the Floodway District shall not be developed nor encumbered in any manner which will cause or contribute to an increase in the base flood water surface elevation at any point within the flood plain. Further, no development shall be permitted which will induce a current flow velocity during the base flood exceeding that set forth in Table 2 of the Flood Insurance Study, City of Sylvania, for the nearest listed reference location.
(2) The bed or floor of the stream channel of a floodway may not be encroached upon or altered in any fashion except by the City as part of improved flood control measures or other improvement consistent with the provisions of this Chapter.
(c) Permitted Uses. To the extent not otherwise prohibited by subdivision rules and regulations, the Building Code or other City regulations, the following uses having a low flood damage potential, and which do not adversely affect the efficiency, restrict the capacity or cause hazardous flow velocities in the channels or floodways of the streams, the tributaries thereof, drainage ditches or any other drainage facility or system permitted by base zoning in any portion of a base zoning district included within the Floodway District shall be permitted in that portion of the Floodway District which includes such base zoning district:
(1) Agricultural uses including, but not limited to the following: general farming, pasturing, grazing, outdoor plant nurseries, horticulture, viticulture, truck farming, forestry, sod farming, and wild crop harvesting.
(2) Commercial uses such as parking areas, loading areas, marinas and boat rentals.
(3) Open space use such as arboretums, parks, wildlife and nature preserves, game farms, fish hatcheries and hunting and fishing areas.
(4) Residential uses such as lawns, gardens, parking areas and play areas.
(5) Recreational uses (public or private) such as golf courses, tennis courts, driving ranges, archery ranges, open-air ice skating facilities, picnic grounds, boat launching ramps, swimming areas and hiking and bike trails.
(6) Transient activities such as carnivals and circuses.
(7) Public utilities and services including underground culverts and pipes, streets, roads and railroads not requiring fill, and river crossing of bridges and transmission and telephone lines above the regulatory flood protection elevation.
(d) Fill. No fill of any type or quantity shall be deposited within any part of the Floodway District.
(e) Structures. No new structure of any type, whether temporary or permanent, shall be erected within the Floodway District.
(f) Manufactured Homes. No manufactured home, recreational vehicle, trailer of any type or other form of mobile or portable structures may be located, maintained or stored within the Floodway District.
(g) Storage. Storage of materials, equipment and/or substances of any nature shall be prohibited within this District. Excepted are self-mobile, nonbuoyant machinery such as automobiles, trucks, truck-tractors, tractors, bulldozers and similar equipment.
