1177.03 STATEMENT OF PURPOSE.
It is the purpose of this chapter to promote the public health, safety and general welfare and to minimize those losses described in Section 1177.02(a) by provisions designed to:
(a) Restrict or prohibit uses which are dangerous to health, safety or property in times of flood or cause excessive increases in flood heights or velocities.
(b) Require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction.
(c) Protect individuals from buying lands which are unsuited for intended purposes because of flood hazard.
(Ord. 76-23. Passed 12-20-76.)
1177.04 DEFINITIONS.
Unless specifically defined below, words or phrases used in this chapter shall be interpreted so as to give them the meaning they have in common usage and to give this chapter its most reasonable application.
(a) "Accessory use or structure" means a use or structure on the same lot with, and of a nature customarily incidental and subordinate to, a principal use or structure.
(b) "Board" means the Board of Appeals.
(c) "Development" means any man-made change to improved or unimproved real estate including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling.
(d) "Equal degree of encroachment" means a standard applied in determining the location of encroachment limits so that flood plain lands on both sides of a stream are capable of conveying a proportionate share of floodflows. This is determined by considering the effect of encroachment on the hydraulic efficiency of the flood plain along both sides of a stream for a significant reach.
(e) "Flood" means a temporary rise in stream level that results in inundation of areas not ordinarily covered by water.
(f) "Floodway" means the channel of the watercourse and those portions of the adjoining flood plains which are reasonably required to carry and discharge the regional flood.
(g) "Floodway fringe" means that portion of the regional flood plain located outside of the floodway.
(h) "Flood frequency" means the average frequency statistically determined, for which it is expected that a specific flood level or discharge may be equaled or exceeded.
(i) "Obstruction" means any dam, wall, wharf, embankment, levee, dike, pile, abutment, projection, excavation, channel, rectification, bridge, conduit, culvert, building, wire, fence, rock, gravel, refuse, fill, structure or matter in, along, across or projecting into any channel, watercourse or regional flood hazard area which may impede, retard or change the direction of the flow of water, either in itself or by catching or collecting debris carried by such water, or that is placed where the flow of water might carry the same downstream to the damage of life or property.
(j) "Person" means any natural person, firm, partnership, association or corporation, but does not include any governmental unit.
(k) "Reach" means a hydraulic engineering term to describe longitudinal segments of a stream or river. A reach will generally include the segment of the flood hazard area where flood heights are influenced by a man-made or natural obstruction. In an urban area, the segment of a stream or river between two consecutive bridge crossings would typically constitute a reach.
(l) "Regional flood" means a flood which is representative of large floods known to have occurred generally in the area and reasonably characteristic of what can be expected to occur on a particular stream. The regional flood generally has a frequency approximately 100 years as is determined by an analysis of floods in a particular stream and other streams in the same general region.
(m) "Regional flood plain" means the area inundated by the regional flood (100 year frequency flood). This is the flood plain area which shall be regulated by the standards and criteria in this chapter.
(n) "Flood protection elevation" means the elevation to which uses regulated by this chapter are required to be elevated or floodproofed.
(o) "Structure" means anything constructed or erected, on the ground or attached to the ground, including but without limitation to buildings, factories, sheds, cabins, mobile homes and other similar uses.
(Ord. 76-23. Passed 12-20-76.)
1177.05 LANDS TO WHICH CHAPTER APPLIES; ESTABLISHMENT OF FLOOD PROTECTION ELEVATION.
(a) This chapter shall apply to all lands within the jurisdiction of Mayfield Village shown on the Official Zoning Map as being located within the boundaries of the Regional Flood Plain District.
(b) The flood protection elevation and necessary floodway areas shall be established by the Board of Appeals as provided in Section 1177.20(b).
(Ord. 76-23. Passed 12-20-76.)
1177.06 ADOPTION OF OFFICIAL ZONING MAP.
The Official Zoning Map, together with all explanatory matter thereon and attached thereto, is hereby adopted by reference and declared to be a part of this chapter. The Official Zoning Map will be on file in the office of the Clerk of Council.
(Ord. 76-23. Passed 12-20-76.)
1177.07 RULES FOR INTERPRETATION OF DISTRICT BOUNDARIES.
The boundaries of the Regional Flood Plain District shall be determined by scaling distances on the Official Zoning Map. Where interpretation is needed as to the exact location of the boundaries of the district as shown on the Official Zoning Map the Board of Appeals shall make the necessary interpretation. The person contesting the location of the district boundary shall be given a reasonable opportunity to present his case to the Board and to submit his own technical evidence if he so desires.
(Ord. 76-23. Passed 12-20-76.)
