<br />-Flood Insurance Rate Map (FIRM) means an official map of a community, on
<br />which the Federal Emergency Management Agency has delineated both the areas
<br />of special flood hazard and the risk premium zones applicable to the community.
<br />-Floodway means the channel of a river or other watercourse and the adjacent
<br />land areas that must be reserved in order to discharge the base flood without
<br />cumulatively increasing the water surface elevation more than one foot.
<br />-Floor means the top surface of an enclosed area in a building (including
<br />basement), i.e., the top of slab in concrete slab construction or top of wood
<br />flooring in wood frame construction. The term does not include the floor of
<br />a garage used solely for parking vehicles.
<br />-Functionally dependent facility means a facility which cannot be used for
<br />its intended purpose unless it is located or carries out in close proximity
<br />to water, such as a docking or port facility necessary for the loading and
<br />unloading of cargo or passengers, shipbuilding, ship repair, or seafood
<br />processing facilities. The term does not include long-term storage,
<br />manufacture, sales, or service facilities.
<br />-Highest adjacent ~rade means the highest natural elevation of the ground
<br />surface, prior to construction, next to the proposed walls of a structure.
<br />-Mean sea level means the average height of the sea for all stages of the
<br />tide. It is used as a reference for establishing various elevations within
<br />the flood plain. For purposes of this ordinance, the term is synonymous with
<br />National Geodetic Vertical Datum (NGVD).
<br />-Manufactured home means a structure, transportable in one or more sections,
<br />which is built on a permanent chassis and designed to be used with or without
<br />a permanent foundation when connected to the required utilities. The term
<br />also includes park trailers, travel trailers, and similar transportable
<br />structures placed on a site for 180 consecutive days or longer and intended
<br />to be improved property.
<br />-National Geodetic Vertical Datum (NGVD) as corrected in 1929 is a vertical
<br />control used as a reference for establishing varying elevations within the
<br />flood plain.
<br />-New construction means structures for which the "start of construction"
<br />commenced on or after the effective date of this ordinance.
<br />-Start of construction (for other than new construction or substantial
<br />improvements under the Coastal Barrier Resources Act (P. L. 97-348), includes
<br />substantial improvement, and means the date the building permit was issued,
<br />provided the actual start of construction, repair, reconstruction, or
<br />improvement was within 180 days of the permit date. The actual start means
<br />the first placement of permanent construction of a structure (including a
<br />manufactured home) on a site, such as the pouring of slabs or footings,
<br />installation of piles, construction of columns, or any work beyond the stage
<br />of excavation or the placement of a manufactured home on a foundation.
<br />Permanent construction does not include land preparation, such as clearing,
<br />grading and filling; nor does it include the installation of streets and/or
<br />walkways; nor does it include excavation for a basement, footings, piers or
<br />foundations or the erection of temporary forms; not does it include the
<br />installation on the property of accessory buildings, such as garages or sheds
<br />not occupied as dwelling units or not part of the main structure.
<br /> -Structure means a walled and roofed building that is principally above
<br /> ground, a manufactured home, a gas or liquid storage tank, or other man-made
<br /> facilities or infrastructures.
<br /> -Substantial improvement means any combination of repairs, reconstruction,
<br /> alteration, or improvements to a structure, taking place during the life of a
<br /> structure in which the cumulative cost equals or exceeds fifty percent of the
<br /> market value of the structure. The market value of the structure should be
<br /> (1) the appraised value of the structure prior to the start of the initial
<br /> repair or improvement, or (2) in the case of damage, the value of the structure
<br /> prior to the damage occurring. For the purposes of this definition, "sub-
<br /> stantial improvement" is considered to occur when the first alteration of any
<br /> wall, ceiling, floor, or other structural part of the building commences,
<br /> whether or not that alteration affects the external dimensions of the
<br /> structure. The term does not, however, include any project for improvement
<br /> of a structure required to comply with existing health, sanitary, or safety
<br /> code specifications which are solely necessary to assure safe living
<br /> conditions.
<br /> -Variance is a grant of relief from the requirements of this ordinance which
<br /> permits construction in a manner otherwise prohibited by this ordinance where
<br /> specific enforcement would result in unnecessary hardship.
