This land is identified on the community’s Flood Insurance Rate Map as Zone A, A1- 30, AE, AH, AO, AR, and/or A99. 32. “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 of 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. For a substantial improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of the building, whether or not that alteration affects the external dimensions of the building. 33. “Structure” means anything constructed or erected on the ground or attached to the ground, including (but not limited to) buildings, factories, sheds, cabins, factory-built homes, storage tanks, grain storage facilities, and/or other similar uses. 34. “Substantial damage” means damage of any origin sustained by a structure whereby the cost of restoring the structure to its before damage condition would equal or exceed 50 percent of the market value of the structure before the damage occurred. Volunteer labor and donated materials shall be included in the estimated cost of repair. 35. “Substantial improvement” means any improvement to a structure which satisfies either of the following criteria: A. Any repair, reconstruction, or improvement of a structure, the cost of which equals or exceeds 50 percent of the market value of the structure either: (i) before the start of construction of the improvement; or (ii) if the structure has been substantially damaged and is being restored, before the damage occurred. The term does not, however, include 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. B. Any addition which increases the original floor area of a building by 25 percent or more. All additions constructed after the effective date of the first floodplain management regulations adopted by the community shall be added to any proposed addition in determining whether the total increase in original floor space would exceed 25 percent. 36. “Variance” means a grant of relief by a community from the terms of the floodplain management regulations. 37. “Violation” means the failure of a structure or other development to be fully compliant with the community’s floodplain management regulations. 160.02 STATUTORY AUTHORITY, FINDINGS OF FACT AND PURPOSE. 1.
