   DEVELOPMENT. Any human-made change to real property, including but not limited to construction or reconstruction of buildings, installing manufactured homes or travel trailers, installing utilities, construction of roads or bridges, erection of levees, walls or fences, drilling, mining, filling, dredging and storage of materials.

   FLOODPLAIN or FLOOD-PRONE AREA. Any land area susceptible to being inundated by water from any source (see FLOOD).
   FLOODPROOFING. Any combination of structural and non-structural additions, changes or adjustments to structures which reduce or eliminate flood damage to real property or improved real property, water and sanitary facilities, structures and their contents.
   MANUFACTURED HOME. A structure, transportable in one or more sections, which is built on a permanent chassis and is designated for use with or without a permanent foundation when attached to the required utilities.
   NEW CONSTRUCTION. Structures for which the start of construction commenced on or after the effective date of this chapter and includes any subsequent improvements to such structures.
   PERSON. Includes any individuals, corporation, partnership, association or any other entity, including state and local governments and agencies.
   SPECIAL FLOOD HAZARD AREA. The land in the floodplain within a community subject to a 1% or greater chance of flooding in any given year.
   STRUCTURE. For floodplain management purposes, a walled and roofed building, including gas or liquid storage tanks, that is principally above ground. The term includes recreational vehicles and travel trailers on site for more than 180 days.
   SUBSTANTIAL IMPROVEMENT.
      (1)   Any repair, reconstruction or improvement of a structure, the cost of which equals or exceeds 50% of the market value of the structure either: before the improvement or repair is started; or if the structure has been damaged, and is being restored, before the damage occurred.
      (2)   For the purposes 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 regardless of the actual work performed.
      (3)   The term does not, however, include either: any project for improvement of a structure to comply with existing state or local health, sanitary or safety code specifications that are solely necessary to assure safe living conditions; or any alteration of an “historic structure,” provided that the alteration will not preclude the structure’s continued designation as an historic structure.
