Sec. 78-1106. -Regulatory flood protection elevation. Council Exhibit E The regulatory flood protection elevation shall be an elevation no lower than one foot above the elevation of the regional flood plus any increases in flood elevation caused by encroachments on the flood plain that result from designation of a floodway. Sec. 78-1111. -Definitions. Unless specifically defined below, words or phrases used in this article shall be interpreted so as to give them the same meaning as they have in common usage and so as to give this article its most reasonable application. (5) Flood means a temporary increase in the flow or stage of a stream or in the stage of a wetland or lake that results in the inundation of normally dry areas. (7) Flood fringe means that portion of the flood plain outside of the floodway. Flood fringe is synonymous with the term "floodway fringe" used in the flood insurance study. (8) Flood plain means the beds proper and the areas adjoining a wetland, lake or watercourse which have been or hereafter may be covered by the regional flood. (9) Flood proofing means a combination of structural provisions, changes, or adjustments to properties and structures subject to flooding, primarily for the reduction or elimination of flood damages. (10) Floodway means the bed of a wetland or lake and the channel of a watercourse and those portions of the adjoining flood plain which are reasonably required to carry or store the regional flood discharge. ( 11) Lake Minnetonka means the naturally occurring lake shown on all the official maps referenced in this chapter, including all bays, channels, inlets, lagoons, marshland and other water-connected portions, whether naturally occurring or artificially created: a. Defined ordinary high water elevation, 929.4 feet MSL. b. Defined floodplain boundary, 100-year flood, 931.5 feet MSL as established by the Minnehaha Creek Watershed District (MCWD). (12) Lowest floor means the lowest floor of the lowest enclosed area (including basement). An unfinished or flood resistant enclosure, used solely for parking of vehicles, building access, or storage in an area other than a basement area, is not considered a building's lowest floor. (19) Regulatory flood protection elevation means an elevation no lower than one foot above the elevation of the regional flood plus any increases in flood elevation caused by encroachments on the flood plain that result from designation of a floodway. a. The regulatory flood protection elevation within the floodway and flood fringe districts, except for Lake Minnetonka, shall be established by adding 1.0 foot to the base flood water surface elevations within floodway listed in the floodway data table contained in the flood insurance study. Regulatory flood protection elevations between cross sections shall be interpolated. b. The regulatory flood protection elevation for Lake Minnetonka shall be 932.5 MSL. c. The regulatory flood protection elevation within the general floodplain district shall be calculated by a qualified registered professional engineer in accordance with procedures set forth in this article. DIVISION 5. -FLOOD FRINGE DISTRICT (FF) Sec. 78-1118. -Permitted uses. (a) The uses listed in section 78-1114 of this article shall be permitted uses.
