For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
ACCESSORY STRUCTURE. Structures that are located on the same parcel of property as the principal structure and the use of which is incidental to the use of the principal structure. Garages, carports and storage sheds are common urban accessory structures.
ADDITION (TO AN EXISTING BUILDING)
.
An extension or increase in the floor area or height of a building or structure. ADDITIONS TO EXISTING BUILDINGS shall comply with the requirements for new construction, unless the addition, renovation or reconstruction to any building that was constructed prior to the initial flood insurance study for that area, and the addition, renovation or reconstruction does not equal 50% of the present market value of the structure. Where a firewall is provided between the addition and the existing building, the addition(s) shall be considered a separate building and must comply with the standards for new construction.
APPEAL. A request for a review of the Administrator’s interpretation of any provision of this chapter.
AREA OF SPECIAL FLOOD HAZARD. The land in the flood plain within a community subject to a 1% or greater chance of being flooded in any given year.

EXISTING CONSTRUCTION
.
For the purposes of determining rates, structures for which the start of construction commenced before the effective date of the FIRM or before January 1, 1975, for FIRMs effective before that date. EXISTING CONSTRUCTION may also be referred to as EXISTING STRUCTURES.
EXISTING MANUFACTURED HOME PARK or MANUFACTURED HOME 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 August 11, 1987, (the effective date of original flood damage prevention chapter.)
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 manufactured homes are to be affixed (including the installation of utilities, the construction of streets and either final site grading or the pouring of concrete slabs).
FLOOD or FLOODING. A general and temporary condition of partial or complete inundation of normally dry land areas from:
(1) The overflow of inland or tidal waters; and
(2) The unusual and rapid accumulation of runoff of surface waters from any source.

FLOOD INSURANCE STUDY. The engineering study performed by the Federal Emergency Management Agency to identify flood hazard areas, flood insurance risk zones and other flood data in a community. The study includes flood boundary and floodway maps (FBFMs), flood hazard boundary maps (FHBMs) and/or flood insurance rate map (FIRMs).
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 1 foot.
FLOOR. The top surface of an enclosed area in a building (including basement), i.e., top of slab in concrete slab construction or top of wood flooring in wood frame construction. The term does not include the floor of a garage used solely for parking vehicles.
FUNCTIONALLY DEPENDENT FACILITY. A facility which cannot be used for its intended purpose unless it is located or carried out in close proximity to water, such as a docking or port facility necessary for the loading and unloading of cargo or passengers, shipbuilding, ship repair or seafood processing facilities. The term does not include long-term storage, manufacture, sales or service facilities.
HIGHEST ADJACENT GRADE. The highest natural elevation of the ground surface, prior to construction, next to the proposed walls of the structure.
HISTORIC STRUCTURE. Any structure that is:
(1) Listed individually in the National Register of Historic Places (a listing maintained by the U.S. Department of Interior) or preliminarily determined by the Secretary of Interior as meeting the requirements for individual listing on the National Register;
(2) Certified or preliminarily determined by the Secretary of 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;
(3) Individually listed on a state inventory of historic places; and/or
(4) Individually listed on a local inventory of historic places in communities with historic preservation programs that have been certified by an approved state program as determined by the Secretary of Interior, or directly by the Secretary of Interior in states without approved programs.
LOWEST FLOOR
.
For flood plain management and flood insurance purposes, the lowest floor of the lowest enclosed area (including basement). An unfinished or flood resistant enclosure, usable 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 an enclosure is not built so as to render the structure in violation of the applicable non-elevation design requirements of this chapter.
MANUFACTURED HOME. A structure, transportable in 1 or more sections, which is built on a permanent chassis and designed to be used with or without a permanent foundation when connected to the required utilities. The term MANUFACTURED HOME does not include a “recreational vehicle.”
MANUFACTURED HOME PARKOR SUBDIVISION. A parcel (or contiguous parcels) of land divided into 2 or more manufactured home lots for rent or sale.
MEAN SEA LEVEL. For purposes of the NFIP, the National Geodetic Vertical Datum (NGVD) of 1929 or other datum, to which base flood elevations shown on a FIRM are referenced.
NEW CONSTRUCTION. For flood plain management purposes, structures for which the start of construction commenced on or after the effective date of this chapter and includes any subsequent improvements to structures.
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 slabs) is completed on or after August 11, 1987, (the effective date of original flood damage prevention chapter.)
NONCONFORMING BUILDING OR USE. Any legally existing building or use which fails to comply with the provisions of this chapter.
POLE BARNS, HAY SHEDS AND THE LIKE. Accessory structures on farms, and may or may not be located on the same parcel as the farm dwelling or shop building.
RECREATIONAL VEHICLE. A vehicle which is: built on a single chassis; 400 square feet or less when measured at the largest horizontal projection; designed to be self-propelled or permanently towable by a light duty truck; and, designed primarily not for use as a permanent dwelling, but as temporary living quarters for recreational, camping, travel or seasonal use.
REMEDY A VIOLATION. To bring the structure or other development into compliance with state or local flood plain management regulations, or, if this is not possible, to reduce the impacts of its noncompliance. Ways that impacts may be reduced include protecting the structure or other affected development from flood damages, implementing the enforcement provisions of the chapter or otherwise deterring future similar violations or reducing federal financial exposure with regard to the structure or other development.
START OF CONSTRUCTION. Includes substantial improvement, and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition or improvement was within 180 days of the permit date. The actual start means the first placement of permanent construction of a structure (including a manufactured home) on a site, such as the pouring of slabs or footings, installation of piles, 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 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 the building, whether or not that alteration affects the external dimensions of the building.
STRUCTURE. For flood plain management purposes, a walled and roofed building, a manufactured home, a gas or liquid storage tank or other human-made facility or infrastructure that is principally above ground.
SUBSTANTIAL DAMAGE. Damage of any origin sustained by a structure whereby the cost of restoring the structure to its pre-damaged condition would equal or exceed 50% of the market value of the structure before the damage occurred. See definition of “substantial improvement.”
SUBSTANTIAL IMPROVEMENT. Any repair, reconstruction, rehabilitation, 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 which have incurred substantial damage, regardless of the actual repair work performed. The term does not, however, include either: any project of 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, any alteration of a historic structure, provided that the alteration will not preclude the structure’s continued designation as a historic structure.
SUBSTANTIALLY IMPROVED EXISTING MANUFACTURED HOME PARKORSUBDIVISION. Where the repair, reconstruction, rehabilitation or improvement of the streets, utilities and pads equals or exceeds 50% of the value of the streets, utilities and pads before the repair, reconstruction or improvement commenced.
VARIANCE. A grant of relief to a person from the requirements of this chapter, which permits construction in a manner otherwise prohibited by this chapter where specific enforcement would result in unnecessary hardship.
VIOLATION. The failure of a structure or other development to be fully compliant with the community’s flood plain management regulations. A structure or other development without the elevation certificate, other certifications or other evidence of compliance required in §§ 150.25 through 150.44 is presumed to be in VIOLATION until a time as that documentation is provided.
