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.

SUBSTANTIAL IMPROVEMENT. Means any combination of repairs, reconstruction, rehabilitation, addition, or other improvement of a structure, taking place during any one-year period whereby the cost of which equals or exceeds 50% of the market value of the structure before the "start of construction" of the improvement.

(1) Any correction of existing violations of state or community health, sanitary, or safety code specifications which have been identified by the community 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. Is a grant of relief from the requirements of this subchapter.
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 §§ 154.328 and 154.329 is presumed to be in violation until such time as that documentation is provided.
