"Area of special flood hazard" -means the land in the floodplain within a community subject to a one percent or greater chance of flooding in any given 2 2242 year. "Base flood" means a flood, which has a one percent chance of being equaled or exceeded in any given year (also called the "100-year flood"). Base flood is the term used throughout this chapter. "Building" -see "Structure".

"Flood or flooding" means: 1. A general and temporary condition of partial or complete inundation of normally dry land areas from: the overflow of inland or tidal waters; the unusual and rapid accumulation or runoff of surface waters from any source; or mudslides (i.e., mudflows) which are proximately caused by flooding as defined herein and are akin to a river of liquid & flowing mud on the surfaces of normally dry land areas, as when earth is carried by a current of water & deposited along the path of the current. 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 unusual and 3 2242 unforeseeable event which results in flooding as defined in this definition. "Floodplain or flood-prone area" means any land area susceptible to being inundated by water from any source -see "Flooding". "Floodplain Administrator" is the individual appointed to administer and enforce the floodplain management regulations. "Floodplain management" means the operation of an overall program of corrective and preventive measures for reducing flood damage and preserving and enhancing, where possible, natural resources in the floodplain, including but not limited to emergency preparedness plans, flood control works, floodplain management regulations, and open space plans. "Floodplain management regulations" means this chapter and other zoning ordinances, subdivision regulations, building codes, health regulations, special purpose ordinances (such as grading and erosion control) and other application of police power which control development in flood-prone areas. This term describes federal, state or local regulations in any combination thereof, which provide standards for preventing and reducing flood loss and damage. "Governing body" is the local governing unit, i.e. county or municipality that is empowered to adopt and implement regulations to provide for the public health, safety and general welfare of its citizenry.

Individually listed on a state inventory of historic places in states with historic preservation programs which have been approved by the Secretary of Interior; or 4. Individually listed on a local inventory of historic places in communities with historic preservation programs that have been certified either by an approved state program as determined by the Secretary of the Interior or directly by the Secretary of the Interior in states with approved programs. "Manufactured home" means a structure, transportable in one or more sections, which 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" means a parcel (or contiguous 5 2242 parcels) of land divided into two or more manufactured home lots for rent or sale. "New construction", for floodplain management purposes, means structures for which the "start of construction" commenced on or after the effective date of floodplain management regulations adopted by the City, and includes any subsequent improvements to such structures. "One-hundred-year flood" or "100-year flood" -see "Base flood." "Recreational vehicle" means a vehicle, which is 1. Built on a single chassis; 2. 400 square feet or less when measured at the largest horizontal projection; 3. Designed to be self-propelled or permanently towable by a light-duty truck; and 4. Designed primarily not for use as a permanent dwelling but as temporary living quarters for recreational, camping, travel, or seasonal use. "Start of construction" includes substantial improvement and other proposed new development 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 180 days from the date of the permit.
