1. A general and temporary condition of partial or complete inundation of normally dry land areas from:

a. The overflow of inland or tidal waters, and/or

b. The unusual and rapid accumulation of runoff of surface waters from any source, and/or

c. Mudslides (i.e., mudflows) which are proximately caused by flooding as defined in subsection 1b of this definition and are akin to a river of liquid and flowing mud on the surfaces of normally dry land areas, as when earth is carried by a current of water and 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 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 1a of this definition.

FLOOD CONTROL: Any undertaking for the conveyance, control, and dispersal of flood waters.

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 mudslide (i.e., mudflow) and/or flood-related erosion hazards. Also known as a Flood Insurance Study (FIS).

FLOOD INSURANCE RATE MAP (FIRM): The official map on which the Federal Insurance Administration has delineated both the areas of special flood hazard and the risk premium zones applicable to the community. A FIRM that has been made available digitally is called a Digital Flood Insurance Rate Map (DFIRM).

FLOODPLAIN ADMINISTRATOR: The community official designated by title to administer and enforce the floodplain management regulations.

FLOODWAY: The channel of 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. Also referred to as “Regulatory Floodway.”

FLOODWAY: (This definition for RMC 4-3-090, Shoreline Master Program Regulations, use only.) Those portions of a river valley lying streamward from the outer limits of a watercourse upon which flood waters are carried during periods of flooding that occur with reasonable regularity, although not necessarily annually. The floodway shall not include those lands that can reasonably be expected to be protected by flood control devices maintained by or maintained under license from the Federal government, the State, or a political subdivision of the State.

FLOOR AREA, GROSS: The sum of the gross horizontal areas of all floors of a building measured from the exterior face of each wall.

FLOOR AREA, NET: The total of all floor area of a building, excluding stairwells, elevator shafts, mechanical equipment rooms, interior vehicular parking or loading, and all floors below the ground floor, except when used for human habitation or service to the public.

FLOOR AREA RATIO: The gross floor area of all buildings on a lot divided by the lot area.

FLOOR, GROUND: The floor located at or near the adjacent grade or public right-of-way.

FLOWER/PLANTS AND FLORAL SUPPLY: A business involving the retail sale of flowers, house plants, and associated floral supplies.

FRANCHISE RETAIL ARCHITECTURE (OR GENERIC OR CORPORATE ARCHITECTURE): Consists of site layout, buildings, and signs for businesses (usually large format, chain, or franchise retail establishments) that are the same style, color, and material regardless of location.

FUEL DEALERS: Wholesale distribution of fuels with associated bulk fuel storage.


FULFILLMENT CENTER: A building used primarily for the storage and/or consolidation of manufactured goods (and to a lesser extent, raw materials) prior to their distribution to retail customers, retail locations, or other warehouses. A typical fulfillment center has a high level of on-site automation and logistics management. Fulfillment centers are generally characterized by a significant storage function and direct distribution of ecommerce product to end users. These facilities usually handle smaller packages and quantities than other types of warehouses, and operations at these facilities often include employees fulfilling online orders by picking, packing, and shipping the goods and materials directly to online retail customers. These qualities, large scale, and volume of goods moved directly to home customer delivery differentiate it from other kinds of warehouse distribution. This definition excludes warehousing, and warehousing and distribution.
