BASE FLOOD. The flood having a one percent (1%) chance of being equaled or exceeded in any given year.
BASE FLOOD ELEVATION. The elevation of the "regional flood." The term "base flood elevation" is used in the flood insurance study.
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 Code exist, and
(2) The structure and/or land use conform to the comprehensive land use plan if one exists and are compatible with the existing neighborhood.
CRITICAL FACILITIES. Facilities necessary to a community's public health and safety, those that store or produce highly volatile, toxic or water-reactive materials, and those that house occupants that may be insufficiently mobile to avoid loss of life or injury. Examples of critical facilities include hospitals, correctional facilities, schools, daycare facilities, nursing homes, fire and police stations, wastewater treatment facilities, public electric utilities, water plants, fuel storage facilities, and waste handling and storage facilities.
DEVELOPMENT. Any man-made 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 flood plain lands on both sides of a stream are capable of conveying a proportionate share of flood flows.
FARM FENCE. An open type of fence of posts and horizontally run wire, further defined by M.S. § 344.02, Subd. l(a)-(d), and is not considered to be a structure under this chapter. Fences that have the potential to obstruct flood flows, such as chain link fences and rigid walls, are regulated as structures under this chapter.
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. The portion of the Special Flood Hazard Area (one percent (1%) annual chance flood) located outside of the floodway. Flood fringe is synonymous with the term "floodway fringe" used in the Flood Insurance Study.
FLOOD INSURANCE RATE MAP (FIRM). An official map on which the Federal Insurance Administrator has delineated both the special hazard areas and the risk premium zones applicable to the community. A FIRM that has been made available digitally is called a Digital Flood Insurance Rate Map (DFIRM).
FLOOD PRONE AREA. Any land susceptible to being inundated by water from any source, as identified by the city flood prone map, or as determined by the local zoning administrator or City Engineer.
FLOOD PLAIN. 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 flood plain 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; provided, that such enclosure is not built so as to render the structure in violation of the applicable non-elevation design requirements of 44 Code of Federal Regulations, Part 60.3.
MANUFACTURED HOME. A structure, transportable in one (1) or more sections, which when erected on site is three hundred and twenty (320) or more square feet, and which is built on a permanent chassis and designed to be used as a single family dwelling with or without a permanent foundation when connected to the required utilities, and includes the plumbing, heating, air conditioning, and electrical systems contained therein. The term MANUFACTURED HOME does not include the term RECREATIONAL VEHICLE.
NEW CONSTRUCTION. Structures, including additions and improvements, and placement of manufactured homes, for which the start of construction commenced on or after the effective date of this chapter.
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 flood plain 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.
ONE HUNDRED YEAR FLOOD PLAIN. Lands inundated by the REGIONAL FLOOD (see definition).
PRINCIPAL USE OR STRUCTURE. All uses or structures that are not accessory uses or structures.
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 four hundred (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 chapter, 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 one percent (1%) chance or one hundred (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 (1) 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.
REPETITIVE LOSS. Flood related damages sustained by a structure on two (2) separate occasions during a ten (10)-year period for which the cost of repairs at the time of each such flood event on the average equals or exceeds twenty-five percent (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 Flood Plain."
START OF CONSTRUCTION. Includes substantial improvement, and means the actual start of construction, repair, reconstruction, rehabilitation, addition, placement or other improvement that occurred before the permit's expiration date. The actual start is either the first placement of permanent construction of a structure on a site, such as the pouring of slab or footings, the installation of piles, the construction of columns, or any work beyond the stage of excavation; or the placement of a manufactured home on a foundation. Permanent construction does not include land preparation, such as clearing, grading and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers, foundations, or the erection of temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or not part of the main structure. For a substantial improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building.
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, decks, manufactured homes, recreational vehicles not considered travel ready as detailed in § 152.101(B) of this chapter and other similar items.
SUBSTANTIAL DAMAGE. Means damage of any origin sustained by a structure where the cost of restoring the structure to its before damaged condition would equal or exceed fifty percent (50%) of the market value of the structure before the damage occurred.
SUBSTANTIAL IMPROVEMENT. Within any consecutive three hundred and sixty-five (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 fifty percent (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, or
(2) Any alteration of a "historic structure," provided that the alteration will not preclude the structure's continued designation as a "historic structure." For the purpose of this chapter, "historic structure" is as defined in 44 Code of Federal Regulations, Part 59.1.
