EXISTING CONSTRUCTION. Any structure for which the “start of construction” commenced before the effective date of the community’s Flood Insurance Rate Map. May also be referred to as EXISTING STRUCTURE.
EXISTING FACTORY-BUILT HOME PARK OR SUBDIVISION. A factory-built home park or subdivision for which the construction of facilities for servicing the lots on which the factory-built 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 effective date of floodplain management regulations adopted by the community.

FLOODWAY. The channel, of a river or stream and those portions of the floodplains adjoining the channel, which are reasonably required to carry and discharge flood waters or flood flows so that confinement of flood flows to the floodway area will not cumulatively increase the water surface elevation of the base flood by more than one foot.
FLOODWAY FRINGE. Those portions of the floodplain, other than the floodway, which can be filled, leveed or otherwise obstructed without causing substantially higher flood levels or flow velocities.
HISTORIC STRUCTURE.
(1) Places maintained by the Department of Interior, or preliminarily determined by the Secretary of the Interior, as meeting the requirements for individual listing of the National Register;
(2) 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;

(4) Individually listed on a local inventory of historic places in communities with historic preservation programs that have been certified by either:
(a) An approved state program as determined by the Secretary of the Interior; or
(b) Directly by the Secretary of the Interior in states without approved programs.
LOWEST FLOOR.
(1) The floor of the lowest enclosed area in a building including a basement, except when all the following criteria are met:
(a) The enclosed area is designed to flood to equalize hydrostatic pressure during floods with walls or openings that satisfy the provisions of § 7-3-29 of this chapter;

(d) The enclosed are is not a basement, as defined in this section.
(2) In cases where the lowest enclosed area satisfied criteria in divisions (1)(a), (1)(b), (1)(c) and (1)(d) above, the
LOWEST FLOOR is the floor of the next highest enclosed area that does not, satisfy the criteria above.
NEW CONSTRUCTION (NEW BUILDINGS, FACTORY-BUILT HOME PARKS). Those structures or development for which the start of construction commenced on or after the effective date of the Flood Insurance Rate Map.
NEW FACTORY-BUILT HOME PARK OR SUBDIVISION. A factory-built home park or subdivision for which the construction of facilities for servicing the lots on which factory-built 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 an or after the effective date of the effective date of floodplain management regulations adopted by the community.
ONE HUNDRED (100) YEAR FLOOD. A flood, the magnitude of which has a 1% change of being equaled or exceeded in any given year or which, on the average, will be equaled or exceeded at least once every 100 years.
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 a temporary living quarters for recreational, camping, travel or seasonal use.
SPECIAL FLOOD HAZARD AREA. The land within a community subject to the 100-year flood. This land is identified as “Zone A” on the community’s Flood Insurance Rate Map.
START OF CONSTRUCTION. Includes substantial improvement, and means the date the development permit was issued; provided, the actual START of construction, repair, reconstruction, rehabilitation, addition, placement or other improvement, was within 180 days or the permit date. The actual start means either the first placement or permanent construction of a structure on a site, such as pouring of, a slab or footings, the installation of pile, the construction of columns or any work beyond the stage of excavation; or the placement of a factory-built 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.
