Flood Damage Prevention Ordinance

Section 2

2.1 Definition

Unless specifically defined below, words or phrases used in this ordinance shall be interpreted so as to give them the meaning they have in common usage and to give this ordinance its most reasonable application.

  1. "Area of special flood hazard" means the land in the flood plain within a community subject to a one percent or greater chance of flooding in any given year.

  2. "Base Flood" means the flood having a one percent chance of being equaled or exceeded in any given year.

  3. "Breakaway walls" mean any type of wall, whether solid or lattice, and whether constructed of concrete, masonry, wood, metal, plastic or any other suitable building material which are not part of the structural support of the building and which are so designed as to breakaway, under abnormally high tides or wave action, without damage to the structural integrity of the building on which they are used or any buildings to which they might be carried by floodwaters.

  4. "Coastal high hazard area" means the area subject to high velocity waters, including but not limited to, hurricane wave wash or tsunamis. The area is designated on a FIRM as Zone V1-30.

  5. "Development" means any man-made change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations located within the area of special flood hazard.

  6. "Flood" or "flooding" means a general and temporary condition of partial or complete inundation of normally dry land areas from:

    1. The overflow of inland or tidal waters and/or

    2. The unusual and rapid accumulation or runoff of surface waters from any source.

  7. "Flood Insurance Rate Map" (FIRM) means the official map on which the Federal Insurance Administration has delineated both the areas of special flood hazards and the risk premium zones applicable to the community.

  8. "Flood Insurance Study" means the official report provided in which the Federal Insurance Administration has provided flood profiles, as well as the Flood Hazard Boundary-Floodway Map and the water surface elevation of the base flood.

  9. "Lowest floor" means a building's lowest floor is the lowest floor (including basement) of the lowest enclosed area of the structure.

  10. "Mobile home" means a structure that is transportable in one or more sections, built on a permanent chassis, and designed to be used with or without a permanent foundation when connected to the required utilities. It does not include recreational vehicles or travel trailers.

  11. "New construction" means structures for which the "start of construction" commenced on or after the effective date of this ordinance.

  12. "Start of construction" means the first placement of permanent construction of a structure (other than a mobile home) on a site, such as the pouring of slabs or footings or any work beyond the stage of excavation. 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 as part of the main structure. For a structure (other than a mobile home) without a basement or poured footings, the "start of construction" includes the first permanent framing or assembly of the structure or any part thereof on its piling or foundation. For mobile homes not within a mobile home park or mobile home subdivision, "start of construction" means the affixing of the mobile home to its permanent site. For mobile homes within mobile home parks or mobile home subdivisions, "start of construction" is the date on which the construction of facilities for servicing the site on which the mobile home is to be affixed (including, at a minimum, the construction of streets, either final site grading or the pouring of concrete pads, and installation of utilities) is completed.

  13. "Structure" means a walled and roofed building or mobile home that is principally above ground.

  14. "Substantial improvement" means 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:

    1. before the improvement or repair is started, or

    2. if the structure has been damaged and is being restored, before the damage occurred.

    For the purpose of this definition "substantial improvement" is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure. The term does not, however, include either: of a structure to comply with existing state or local health,

    1. any project for improvement of a structure to comply with existing state or local health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions, or

    2. any alteration of a structure listed on the National Register of Historic Places or a State Inventory of Historic Places.

  15. "Variance" means a grant of relief from the requirements of this ordinance which permits construction in a manner that would otherwise be prohibited by this ordinance.
