§ 152.01  DEFINITIONS.
   For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
   APPEAL. A request for review of the City Administrator’s interpretation of any provision of this chapter or a request for a variance.
   AREA OF SHALLOW FLOODING. A designated AO or AH Zone on the Flood Insurance Rate Map (FIRM). The base flood depths range from one to three feet; a clearly defined channel does not exist; the path of flooding is unpredictable and indeterminate; and velocity flow may be evident. AO is characterized as sheet flow and AH indicates ponding.
   AREA OF SPECIAL FLOOD HAZARD. The land in the flood plain within a community subject to a 1% or greater chance of flooding in any given year. Designation on maps always includes the letters A or V.
   BASE FLOOD. The flood having a 1% chance of being equaled or exceeded in any given year. Also referred to as the 100-year flood. Designation on maps always includes the letters A or V.
   CITY ADMINISTRATOR. The City Recorder or other city official appointed by the Mayor with approval of City Council.
   DEVELOPMENT. Any human-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 specified flood hazard.
   FLOOD or FLOODING. A general and temporary condition or 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 of runoff of surface waters from any source.
   FLOOD INSURANCE RATE MAP. 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.
   FLOOD INSURANCE STUDY. The official report provided by the Federal Insurance Administration that includes food profiles, the Flood Boundary-Floodway Map, and the water surface elevation of the base flood.
   FLOODWAY. The channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than one foot.
   LOWEST FLOOR. The lowest floor of the lowest enclosed area (including basement). An unfinished or flood resistant enclosure, usable solely for parking of vehicles, building access, or storage, in an area other than a basement, is not considered a building’s lowest floor, provided that the enclosure is not built so as to render the structure in violation of the applicable non-elevation design requirements of this chapter.
   MANUFACTURED HOME. A structure, transportable in one or more sections, which is built or a permanent chassis and designed for use with or without a permanent foundation when connected to the required utilities. For flood plain management purposes, the term MANUFACTURED HOME also includes park trailers, travel trailers, and other similar vehicles placed on a site for greater than 180 executive days. For insurance purposes, the term MANUFACTURED HOME does not include park trailers, travel trailers, and other similar vehicles.
   MANUFACTURED HOME PARK OR SUBDIVISION. A parcel (or contiguous parcels) of land divided into two or more manufactured home lots for sale or rent.
   NEW CONSTRUCTION. Structures for which the start of construction commenced on or after the effective date of this chapter.
   START OF CONSTRUCTION. Includes substantial improvement, and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, 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 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.
   STRUCTURE. A walled and roofed building including a gas or liquid storage tank that is principally above ground.
   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:
         (a)   Before the improvement or repair is started; or
         (b)   If the structure has been damaged and is being restored, before the damage occurred. 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.
      (2)   The term does not, however, include either:
         (a)   Any project for the 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
         (b)   Any alteration of a structure listed on the National Register of Historic Places or State Inventory of Historic Places.
   VARIANCES. A grant of relief from the requirements of this chapter which permits construction in a manner that would otherwise be prohibited by this chapter.
