(6) Flood frequency means the frequency for which it is expected that a specific flood stage or
<br /> discharge may be equaled or exceeded.
<br /> (7) Flood fringe means that portion of the flood plain outside of the floodway. Flood fringe is
<br /> synonymous with the term "floodway fringe" used in the flood insurance study.
<br /> (8) Flood plain means the beds proper and the areas adjoining a wetland, lake or watercourse which
<br /> have been or hereafter may be covered by the regional flood.
<br /> (9) Flood proofing means a combination of structural provisions, changes, or adjustments to
<br /> properties and structures subject to flooding, primarily for the reduction or elimination of flood
<br /> damages.
<br /> (10) Floodway means the bed of a wetland or lake and the channel of a watercourse and those
<br /> portions of the adjoining flood plain which are reasonably required to carry or store the regional
<br /> flood discharge.
<br /> (11) Lake Minnetonka means the naturally occurring lake shown on all the official maps referenced in
<br /> this chapter, including all bays, channels, inlets, lagoons, marshland and other water-connected
<br /> portions, whether naturally occurring or artificially created:
<br /> a. Defined ordinary high water elevation, 929.4 feet MSL.
<br /> b. Defined floodplain boundary, 100-year flood, 931.5 feet MSL as established by the
<br /> Minnehaha Creek Watershed District(MCWD).
<br /> (12) Lowest f/oor means the lowest floor of the lowest enclosed area (including basement). An
<br /> unfinished or flood resistant enclosure, used solely for parking of vehicles, building access, or
<br /> storage in an area other than a basement area, is not considered a building's lowest floor.
<br /> (13) Manufactured home means a structure, transportable in one or more sections,which is built on a
<br /> permanent chassis and is designed for use with or without a permanent foundation when attached
<br /> to the required utilities. The term "manufactured home" does not include the term "recreational
<br /> vehicle."
<br /> (14) Obstruction means any dam, wall, wharf, embankment, levee, dike, pile, abutment, projection,
<br /> excavation, channel modification, culvert, building, wire, fence, stockpile, refuse, fiil, structure, or
<br /> matter in, along, across, or projecting into any channel, watercourse, or regulatory flood plain
<br /> which may impede, retard, or change the direction of the flow of water, either in itself or by
<br /> catching or collecting debris carried by such water.
<br /> (15) Principa/use or structure means all uses or structures that are not accessory uses or structures.
<br /> (16) Reach means a hydraulic engineering term to describe a longitudinal segment of a stream or river
<br /> influenced by a natural or man-made obstruction. In an urban area, the segment of a stream or
<br /> river between two consecutive bridge crossings would most typically constitute a reach.
<br /> (17) Recreational vehic/e means a vehicle that is built on a single chassis, is 400 square feet or less
<br /> when measured at the largest horizontal projection, is designed to be self-propelled or
<br /> permanently towable by a light duty truck, and is designed primarily not for use as a permanent
<br /> dwelling but as temporary living quarters for recreational, camping, travel, or seasonal use. For
<br /> the purposes of this article, the term recreational vehicle shall be synonymous with the term travel
<br /> trailer/travel vehicle.
<br /> (18) Regiona/ f/ood means a flood which is representative of large fioods known to have occurred
<br /> generally in Minnesota and reasonably characteristic of what can be expected to occur on an
<br /> average frequency in the magnitude of the 100-year recurrence interval. Regional flood is
<br /> synonymous with the term "base flood" used in a flood insurance study.
<br /> (19) Regu/atory f/ood protection e/evation means an elevation no lower than one foot above the
<br /> elevation of the regional flood plus any increases in flood elevation caused by encroachments on
<br /> the flood plain that result from designation of a floodway.
