Section 410.050 Definitions.

[R.O. 2009 §17.44.050]
Unless specifically defined below, words or phrases used in this Chapter shall be interpreted so as to give them the meaning they have in common usage and to give this Chapter its most reasonable application.
ACTUARIAL RATES OR RISK PREMIUM RATES
Those rates established by the Federal Insurance Administrator pursuant to individual community studies and investigations which are undertaken to provide flood insurance in accordance with Section 1307 of the Act and accepted actuarial principles. "Risk premium rates" include provisions for operating cost and allowances.
APPEAL
A request for a review of the City Administrator's interpretation of any provision of this Chapter or a request for a variance.
AREA OF SPECIAL FLOOD HAZARD
The land in the floodplain within a community subject to a one percent (1%) or greater chance of flooding in any given year.
BASE FLOOD
The flood having a one percent (1%) chance of being equaled or exceeded in any given year.
BASEMENT
Any area of the building having its floor subgrade (below ground level) on all sides.
CHANNEL
A natural or artificial watercourse of perceptible extent, with a definite bed and banks to confine and conduct continuously or periodically flowing water. Channel flow, thus, is that water which is flowing within the limits of a defined channel.
DEVELOPMENT
Any manmade change to improved or unimproved real estate including, but not limited to, buildings or other structures, levees, levee systems, mining, dredging, filling, grading, paving, excavation or drilling operations or storage of equipment or materials.
EXISTING CONSTRUCTION
For the purposes of determining rates, structures for which the "start of construction" commenced before the effective date of the FIRM or before January 1, 1975, for FIRMs effective before this date. "Existing construction" may also be referred to as "existing structures".
FLOOD OR FLOODING
1. 
General and temporary condition of partial or complete inundation of normally dry land areas from (1) The overflow of inland; and/or (2) The unusual and rapid accumulation or runoff of surface waters from any source.
2. 
The collapse or subsidence of land along the shore of a lake or other body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels or suddenly caused by an unusually high water level in a natural body of water, accompanied by a severe storm or by an unanticipated force of nature, such as flash flood or an abnormal tidal surge or by some similarly unusual and unforeseeable event which results in flooding as defined in Subsection (1) of this definition.
FLOOD INSURANCE RATE MAP (FIRM)
An official map of a community on which the Federal Insurance Administrator has delineated both the special hazard areas and the risk premium zones applicable to the community.
FLOOD INSURANCE STUDY OR FLOOD ELEVATION STUDY
An examination, evaluation and determination of flood hazards and, if appropriate, corresponding water surface elevations or an examination, evaluation and determination of mudslides (i.e., mudflow) and/or flood-related erosion hazards.
FLOOD PROTECTION SYSTEM
Those physical structural works for which funds have been authorized, appropriated and expended and which have been constructed specifically to modify flooding in order to reduce the extent of the area within a community subject to a "special flood hazard" and the extent of the depths of associated flooding. Such system typically includes dams, reservoirs, levees or dikes. These specialized flood-modifying works are those constructed in conformance with sound engineering standards.
FLOODPLAIN MANAGEMENT
The operation of an overall program of corrective and preventive measures for reducing flood damage including, but not limited to, emergency preparedness plans, flood control works and floodplain management regulations.
FLOODPROOFING
Any combination of structural and non-structural additions, changes or adjustments to structures which reduce or eliminate flood damage to real estate or improved real property, water and sanitary facilities, structures and their contents.
FLOODWAY OR REGULATORY 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 a designated height.
FLOODWAY FRINGE
That area of the floodplain, outside of the floodway, that on the average is likely to be flooded once every one hundred (100) years (i.e., that has a one percent (1%) chance of flood occurrence in any one (1) year).
FREEBOARD
A factor of safety usually expressed in feet above a flood level for purposes of floodplain management. Freeboard tends to compensate for the many unknown factors that could contribute to flood heights greater than the height calculated for a selected size flood and floodway conditions, such as wave action, clogged bridge openings and the hydrological effect of urbanization of the watershed.
HIGHEST ADJACENT GRADE
The highest natural elevation of the ground surface prior to construction next to the proposed walls of a structure.
HISTORIC STRUCTURE
Any structure that is:
1. 
Listed individually in the National Register of Historic Places (a listing maintained by the Department of the Interior) or preliminarily determined by the Secretary of the Interior as meeting the requirements for individual listing on the National Register;
2. 
Certified or preliminarily determined by the Secretary of the Interior as contributing to the historical significance of a registered historic district or a district preliminarily determined by the Secretary to qualify as a registered historic district;
3. 
Individually listed on a State Inventory of Historic Places in States with historic preservation programs which have been approved by the Secretary of the Interior; or
4. 
Individually listed on a local inventory of historic places in communities with historic preservation programs that have been certified either:
a. 
By an approved State program as determined by the Secretary of the Interior; or
b. 
Directly by the Secretary of the Interior in States without approved programs.
LOWEST FLOOR
The lowest floor of the lowest enclosed area (including basement). An unfinished or flood-resistant enclosure, usable solely for parking vehicles, building access or storage in an area other than a basement area is not considered a building's lowest floor; provided that such enclosure is not built so as to render the structure in violation of the applicable non-elevation design requirements.
MANUFACTURED HOME
A structure transportable in one (1) or more sections that is built on a permanent chassis and is designed for use with or without a permanent foundation when attached to the required utilities. The term "manufactured home" does not include a "recreational vehicle".
MANUFACTURED HOME PARK OR SUBDIVISION
A parcel (or contiguous parcels) of land divided into two (2) or more manufactured home lots for rent or sale.
START OF CONSTRUCTION
For other than new construction or substantial improvement under Coastal Barrier Resources Act Pub. L. 97-348, includes substantial improvement and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition, placement or other improvement was within one hundred eighty (180) days of permit date. The "actual start" means either the first (1st) 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 the installation of street 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 the construction" means the first (1st) alteration of any wall, ceiling, floor or other structural part of building, whether or not that alteration affects the external dimensions of the building.
STRUCTURE
For floodplain management purposes, a walled and roofed building, including a gas or liquid storage tank, that is principally above ground, as well as a manufactured home. "Structure", for insurance purposes, means a walled and roofed building, other than gas or liquid storage tank, that is principally above ground and affixed to a permanent site, as well as a manufactured home on a permanent foundation. For the latter purpose, the term includes a building while in the course of construction, alteration or repair, but does not include building materials or supplies intended for use in such construction, alteration or repair, unless such materials or supplies are within an enclosed building on the premises.
SUBSTANTIAL DAMAGE
Damage of any origin sustained by a structure whereby the cost of restoring the structure to its before-damaged condition would equal or exceed fifty percent (50%) of the market value of the structure before the damage occurred.
SUBSTANTIAL IMPROVEMENT
Any reconstruction, rehabilitation, addition or other improvement of a structure, the cost of which equals or exceeds fifty percent (50%) of the market value of the structure before the "start of construction" or the improvement. This term includes structures which have incurred "substantial damage", regardless of the actual repair work performed. The term does not, however, include either:
1. 
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, 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
A grant of relief to a person from the requirements of this Chapter, which permits construction in manner otherwise prohibited by this Chapter, where specific enforcement would result in unnecessary hardship.
