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 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 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 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

the cost of restoring the structure to its before-damaged condition
would equal or exceed 50 percent of the market value of the structure
before the damage occurred.
SUBSTANTIAL IMPROVEMENT
Means any reconstruction, rehabilitation, addition, or other
improvement of a structure, the cost of which equals or exceeds 50
percent 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:
A.
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 conditions; or
B.
Any alteration of a "historic structure," provided that the
alteration will not preclude the structure's continued designation
as a "historic structure."
VARIANCE
Means a grant of relief by a community from the terms of
a floodplain management regulation. (For full requirements see Section
60.6(a) of the National Flood Insurance Program regulations).
VIOLATION
Means 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 Section 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.
WATER SURFACE ELEVATION
Means the height, in relation to the National Geodetic Vertical
Datum (NGVD) of 1929 (or other datum, where specified), of floods
of various magnitudes and frequencies in the floodplains of coastal
