Coastal high hazard area: A special flood hazard area extending from offshore to the inland limit of a primary frontal dune along an open coast and any other area subject to high velocity wave action from storms or seismic sources. Coastal high hazard areas are also referred to as " high hazard areas subject to high velocity wave action" or " V Zones" and are designated on Flood Insurance Rate Maps ( FIRM) as Zone VI- V30, VE, or V.

Area with a floodplain subject to a 1- percent or greater chance of flooding in any year; or 2. Area designated as a flood hazard area on the community' s flood hazard map, or otherwise legally designated. Design flood elevation: The elevation of the " design flood," including wave height, relative to the datum specified on the City' s legally designated flood hazard map. In areas designated as Zone AO, the design flood elevation shall be the elevation of the highest existing grade of the building' s perimeter plus the depth number ( in feet) specified on the flood hazard map. In areas designated as Zone AO where the depth number is not specified on the map, the depth number shall be taken as being equal to 2 feet. [ Also defined in FBC, B, Section 1612. 2. 1 Development: Any man -made change to improved or unimproved real estate, including but not limited to, buildings or other structures, tanks, temporary structures, temporary or permanent storage of equipment or materials, mining, dredging, filling, grading, paving, excavations, drilling operations or any other land disturbing activities. Encroachment: The advancement or infringement of fill, excavation, buildings, permanent structures or other development into a flood hazard area which may impede or alter the flow capacity of riverine flood hazard areas.

Expansion to an existing manufactured home park or subdivision: The preparation of additional sites by the construction of facilities for servicing the lots on which the manufactured homes are to be affixed ( including the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads). Federal Emergency Management Agency ( FEMA): The Federal agency that, in addition to carrying out other functions, administers the National Flood Insurance Program. Flood or flooding: A general and temporary condition of partial or complete inundation of normally dry land from: [ Also defined in FBC, B, Section 1612. 2.] 1. The overflow of inland or tidal waters. 2. The unusual and rapid accumulation or runoff of surface waters from any source.

The area designated as a flood hazard area on the community' s flood hazard map, or otherwise legally designated. Flood Insurance Rate Map ( FIRM): The official map of the City on which the Federal Emergency Management Agency has delineated both special flood hazard areas and the risk premium zones applicable to the City. [ Also defined in FBC, B, Section 1612. 2.] Flood Insurance Study ( FIS):The official report provided by the Federal Emergency Management Agency that contains the Flood Insurance Rate Map, the Flood Boundary and Floodway Map ( if applicable), the water surface elevations of the base flood, and supporting technical data.
