The definitions set forth in Article II of Chapter 295, Zoning, and Article II of Chapter 250, Subdivision and Land Development, are incorporated herein by reference.
As used in this chapter, the following terms shall have the meanings indicated:
BANKFULL (STAGE)
The incipient elevation on the bank of a stream where flooding begins. The bankfull stage is associated with the flow that just fills the channel to the top of its banks, a point where the water begins to overflow onto a floodplain.
BASE FLOOD
A flood which has a one percent chance of being equaled or exceeded in any given year (also called the "one-hundred-year flood" or "one-percent-annual-chance flood").
BASE FLOOD ELEVATION (BFE)
The elevation shown on the Flood Insurance Rate Map (FIRM) for Zones AE, AH, A1-30 that indicates the water surface elevation resulting from a flood that has a one-percent or greater chance of being equaled or exceeded in any given year.
BASEMENT
That portion of a building that is partially or wholly below ground level. This portion serves as a substructure of foundation for a building. A basement shall be counted as a story for the purpose of height measurement, if the vertical distance between the ceiling and the average level of the adjoining ground is more than five feet. Also, any area of a building having its floor below ground level on all sides.
COMPLETELY DRY SPACE
A space which will remain totally dry during flooding; the structure is designed and constructed to prevent the passage of water and water vapor.
DESIGNATED FLOODPLAIN AREA
A relatively flat or low land area adjoining a river, stream or watercourse which is subject to partial or complete inundation in a one-hundred-year flood, as designated on the FIRM.
DEVELOPMENT
Any man-made change to improved or unimproved real estate, including but not limited to the construction, reconstruction, renovation, repair, expansion, or alteration of buildings or other structures, the placement of manufactured homes, streets and other paving, utilities, filling, grading and excavation, mining, dredging, drilling operations, storage of equipment or materials, and the subdivision of land.
ESSENTIALLY DRY SPACE
A space which will remain dry during flooding, except for the passage of some water vapor or minor seepage; the structure is substantially impermeable.
EXISTING MANUFACTURED HOME PARK OR SUBDIVISION
A manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including, at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads) is completed before the effective date of the floodplain management regulations adopted by a community.
EXPANSION TO AN EXISTING MANUFACTURED HOME PARK OR SUBDIVISION
The preparation of additional sites by the construction of facilities for servicing the lots on which the manufacturing homes are to be affixed (including the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads).
FLOOD
A temporary inundation of normally dry land areas.
FLOOD INSURANCE RATE MAP (FIRM)
The official map on which the Federal Emergency Management Agency has delineated both the areas of special flood hazards and the risk premium zones applicable to the community.
FLOOD INSURANCE STUDY (FIS)
The official report provided by the Federal Emergency Management Agency that includes flood profiles, the Flood Insurance Rate Map, the Flood Boundary and Floodway Map, and the water surface elevation of the base flood.
FLOODPLAIN AREA
A relatively flat or low land area which is subject to partial or complete inundation from an adjoining or nearby stream, river or watercourse; and/or any area subject to the unusual and rapid accumulation of surface waters from any source.
FLOODPROOFING
Any combination of structural and nonstructural addition, changes, or adjustments to proposed or existing structures which reduce or eliminate flood damage to real estate or improved real property, water and sanitary facilities, structures and their contents.
FLOODWAY
The channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than one foot.
FLOOR, LOWEST
The lowest floor of the lowest fully enclosed area (including basement). An unfinished, flood resistant partially enclosed area, used solely for parking of vehicles, building access, and incidental storage in an area other than a basement area is not considered the lowest floor of a building, provided that such space is not designed and built so that the structure is in violation of the applicable nonelevation design requirements of this chapter.
GRADE, HIGHEST ADJACENT
The highest natural elevation of the ground surface prior to construction next to the proposed walls of a structure.
GROUND FLOOR
The floor of a building nearest the mean grade of the front of the building.
HISTORIC STRUCTURE
Any structure that is:
A. 
Listed individually in the National Register of Historic Places (a listing maintained by the Department of the Interior) or preliminarily determined by the Secretary of the Interior as meeting the requirements for individual listing on the National Register;
B. 
Certified or preliminarily determined by the Secretary of the Interior as contributing to the historical significance of a registered historic district or a district preliminarily determined by the Secretary to qualify as a registered historic district;
C. 
Individually listed on a state inventory of historic places in states which have been approved by the Secretary of the Interior; or
D. 
Individually listed on a local inventory of historic places in communities with historic preservation that have been certified either:
(1) 
By an approved state program as determined by the Secretary of the Interior; or
(2) 
Directly by the Secretary of the Interior in states without approved programs.
IDENTIFIED FLOOD-PRONE AREA
The floodplain area specifically identified as being inundated by the one-hundred-year flood. Included would be areas identified as Floodway (FW), Special Floodplain (AE), and Approximate Floodplain Area (A).
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 includes park trailers, travel trailers, recreational and other similar vehicles which are placed on a site for more than 180 consecutive days.
MANUFACTURED/MOBILE HOME PARK/COMMUNITY/SUBDIVISION
A parcel or contiguous parcels of land which has been so designated and improved that it contains two or more manufactured/mobile home lots for the placement thereon of manufactured/mobile homes for non-transient use.
NEW CONSTRUCTION DATE
Structures for which the start of construction commenced on or after the date of the municipality's first floodplain management ordinance was adopted January 3, 1984, and includes any subsequent improvements thereto. Any construction started after January 3, 1984 and before January 18, 2012, is subject to the ordinance in effect at the time the permit was issued, provided the start of construction was within 180 days of permit issuance.
NEW MANUFACTURED HOME PARK OR SUBDIVISION
A manufactured home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including, at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads) is completed on or after the effective date of floodplain management regulations adopted by a community.
OBSTRUCTION
Any wall, dam, wharf, embankment, levee, dike, projection, excavation, channel, rectification, culvert, building, fence, stockpile, refuse, fill, structure, or matter in, along, across, or projecting into any channel, watercourse, or flood-prone 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 is placed where the flow of the water might carry the same down stream to the damage of life and property.
RECREATIONAL VEHICLE

A. 
Built on a single chassis;
B. 
Not more than 400 square feet, measured at the largest horizontal projection;
C. 
Designed to be self-propelled or permanently towable by a light-duty truck;
D. 
Not designed for use as a permanent dwelling but as temporary living quarters for recreations, camping, travel, or seasonal use.
REGULATORY FLOOD ELEVATION
The base flood elevation (BFE) plus a freeboard safety factor of 1 1/2 feet.
SPECIAL FLOOD HAZARD AREA (SFHA)
An area in the floodplain subject to a one-percent or greater chance of flooding in any given year. It is shown on the FIRM as Zone A, AO, A1-A30, AE, A99 or AH.
START OF CONSTRUCTION
Includes substantial improvement and other proposed new development and means the date the permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition, placement, or other improvement was within 180 days from the date of the permit and shall be completed within 12 months after the date of issuance of the permit unless a time extension is granted, in writing, by the Floodplain Administrator. The actual start means 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 manufacture 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 walkways; nor does it include excavation for a basement, footings, piers, or 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
Any man-made object having an ascertainable stationary location on or in land or water, whether or not affixed to the land. For floodplain management purposes, a walled and roofed building, including a gas or liquid storage tank, that is principally above ground, as well as manufactured home.
SUBSTANTIAL DAMAGE
Damage from any cause sustained by a structure whereby the cost of restoring the structure to its before-damaged conditions would equal or exceeds 50% or more of the market value of the structure before the damage occurred.
SUBSTANTIAL IMPROVEMENT
Any repair, alteration, reconstruction of improvement of a structure, and/or use the cost of which equal 50% of its market value either before improvement is started, or if the structure has been damaged and is being restored before the damage occurred. For the purposes of this definition, substantial improvement is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure. The term does not, however, include either any project for improvement of a structure to comply with existing state or local health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions, or any alteration to a structure listed on the National Register of Historic Places or the State Inventory of Historic Places.
TOP OF BANK
The highest point or level of the stream bank, at a break in slope of the stream bank that represents bankfull stream flow. On stream channels where a break in slope is indiscernible the top of bank shall be represented by the elevation of the runoff flow for the storm having a 50% annual chance of being equaled or exceeded.
VIOLATION
The failure of a structure or other development to be fully compliant with the community's floodplain management regulations. A structure or other development without the elevation certificate, other certifications, or other evidence of compliance required in 44 CFR 60.3(b)(5), (c)(4), (c)(10), (d)(3), (e)(2), (e)(4), or (e)(5) is presumed to be in violation until such time as that documentation is provided.
