FLOOD. 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/or

FLOODWAY. The channel of the 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 a designated height.
HISTORIC STRUCTURE. Any structure that is:
(1) Listed individually in the National Register of Historic Places (a listing maintained by the Department of Interior) or preliminarily determined by the Secretary of the Interior as meeting the requirements for individual listing on the National Register;

ONE-HUNDRED-YEAR FLOOD. The condition of flooding having a 1% chance of annual occurrence.
PRINCIPALLY ABOVE GROUND. At least 51% of the actual cash value of the structure is above ground.
RECREATIONAL VEHICLE. A vehicle which is:
(1) Built on a single chassis;
(2) Four-hundred square feet or less when measured at the largest horizontal projection;
(3) Designed to be self-propelled or permanently towable by a light duty truck; and
(4) Designed primarily not for use as a permanent dwelling but as temporary living quarters for recreational, camping, travel, or seasonal use.
REGULATORY FLOOD ELEVATION. The water surface elevation of the 100-year flood.
SPECIAL FLOOD HAZARD AREA. The land in the floodplain within a community subject to 1% or greater chance of flooding in any given year.
START OF CONSTRUCTION. For other than new construction or substantial improvements under the Coastal Barrier Resources Act, being 16 U.S.C. §§ 3501 et seq., includes substantial improvement, and means the date the building permit was issued, provided the actual START OF CONSTRUCTION, repair, reconstruction, rehabilitation, addition, placement, or other improvement was within 180 days of the permit date. The actual START means 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, 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 the alteration affects the external dimensions of the building.
STRUCTURE. A walled and roofed building that is principally above ground, as well as a manufactured home, and a gas or liquid storage tank that is principally above ground.
SUBSTANTIAL DAMAGE. Damage of any origin sustained by a structure whereby 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. Any 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 start of construction of the improvement. This includes structures which 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.
VARIANCE. A grant of relief to a person from the terms of a floodplain management ordinance.
