For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
ACCESSORY USE or STRUCTURE. A use or structure on the same lot with, and of a nature customarily incidental and subordinate to, the principal use or structure.
BASE FLOOD ELEVATION. The elevation of the “regional flood.” The term “base flood elevation” is used in the flood insurance survey.
BASEMENT. Any area of a structure, including crawl spaces, having its floor or base subgrade (below ground level) on all four sides, regardless of the depth of excavation below ground level.
CONDITIONAL USE. A specific type of structure or land use listed in the official control that may be allowed but only after an in-depth review procedure and with appropriate conditions or restrictions as provided in the official zoning controls or building codes and upon a finding that:
(1) Certain conditions as detailed in the zoning ordinance exist.
(2) The structure and/or land use conform to the comprehensive land use plan if one exists and are compatible with the existing neighborhood.
DEVELOPMENT. Any manmade change to improved or unimproved real estate, including buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations, or storage of equipment or materials.
EQUAL DEGREE OF ENCROACHMENT. A method of determining the location of floodway boundaries so that floodplain lands on both sides of a stream are capable of conveying a proportionate share of flood flows.
FARM FENCE. A fence as defined by M.S. § 344.02, Subd. l(a)-(d), as it may be amended from time to time. An open type fence of posts and wire is not considered to be a structure under this subchapter. Fences that have the potential to obstruct flood flows, such as chain link fences and rigid walls, are regulated as structures under this subchapter.
FLOOD. 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.
FLOOD FREQUENCY. The frequency for which it is expected that a specific flood stage or discharge may be equaled or exceeded.
FLOOD FRINGE. That portion of the floodplain outside of the floodway. FLOOD FRINGE is synonymous with the term “floodway fringe” used in the Flood Insurance Study for McLeod County, Minnesota.
FLOOD PRONE AREA Any land susceptible to being inundated by water from any source. (See FLOOD).
FLOODPLAIN. The beds proper and the areas adjoining a wetland, lake or watercourse which have been or hereafter may be covered by the regional flood.
FLOODPROOFING. A combination of structural provisions, changes, or adjustments to properties and structures subject to flooding, primarily for the reduction or elimination of flood damages.
FLOODWAY. The bed of a wetland or lake and the channel of a watercourse and those portions of the adjoining floodplain which are reasonably required to carry or store the regional flood discharge.
LOWEST FLOOR. 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.
MANUFACTURED HOME. A structure, transportable in one or more sections, which is built on a permanent chassis and is designed for use with or without a permanent foundation when attached to the required utilities. The term MANUFACTURED HOME does not include the term “recreational vehicle.”
OBSTRUCTION. Any dam, wall, wharf, embankment, levee, dike, pile, abutment, projection, excavation, channel modification, culvert, building, wire, fence, stockpile, refuse, fill, structure, or matter in, along, across, or projecting into any channel, watercourse, or regulatory floodplain 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.
PRINCIPAL USE or STRUCTURE. All uses or structures that are not accessory uses or structures.
ONE-HUNDRED YEAR FLOODPLAIN. Lands inundated by the “Regional Flood.” (See definition).
REACH. A hydraulic engineering term to describe a longitudinal segment of a stream or river influenced by a natural or man-made obstruction. In an urban area, the segment of a stream or river between two consecutive bridge crossings would most typically constitute a reach.
RECREATIONAL VEHICLE. A vehicle that is built on a single chassis, is 400 square feet or less when measured at the largest horizontal projection, is designed to be self-propelled or permanently towable by a light duty truck, and is designed primarily not for use as a permanent dwelling but as temporary living quarters for recreational, camping, travel, or seasonal use. For the purposes of this subchapter, the term recreational vehicle is synonymous with the term “travel trailer/travel vehicle.”
REGIONAL FLOOD. A flood which is representative of large floods known to have occurred generally in Minnesota and reasonably characteristic of what can be expected to occur on an average frequency in the magnitude of the 1% chance or 100-year recurrence interval. Regional flood is synonymous with the term “base flood” used in a flood insurance study.
REGULATORY FLOOD PROTECTION ELEVATION (RFPE). An elevation not less than one foot above the elevation of the regional flood plus any increases in flood elevation caused by encroachments on the floodplain that result from designation of a floodway.
REPETITIVE LOSS. Flood related damages sustained by a structure on two separate occasions during a ten-year period for which the cost of repairs at the time of each such flood event on the average equals or exceeds 25% of the market value of the structure before the damage occurred.
SPECIAL FLOOD HAZARD AREA. A term used for flood insurance purposes synonymous with “one hundred year floodplain.”
STRUCTURE. Anything constructed or erected on the ground or attached to the ground or on-site utilities, including, but not limited to, buildings, factories, sheds, detached garages, cabins, manufactured homes, recreational vehicles not meeting the exemption criteria specified in § 154.094(C)(1) of this subchapter and other similar items.
SUBSTANTIAL DAMAGE. Damage of any origin sustained by a structure where the cost of restoring the structure to its before damaged condition would equal or exceed 50% of the market value of the structure before the damage occurred.
SUBSTANTIAL IMPROVEMENT Within any consecutive 365-day period, any reconstruction, rehabilitation (including normal maintenance and repair), repair after damage, addition, or other improvement of a structure, the cost of which equals or exceeds 50% of the market value of the structure before the “start of construction” of the improvement. This term includes structures that have incurred “substantial damage,” regardless of the actual repair work performed. The term does not, however, include either:
(1) Any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions.
(2) Any alteration of an “historic structure,” provided that the alteration will not preclude the structure's continued designation as an “historic structure.” For the purpose of this subchapter HISTORIC STRUCTURE is as defined in 44 C.F.R. Part 59.1.
