"Flood" or "flooding"means a general and temporary condition of partial or complete inundation of normally dry land from:
(1) The overflow of inland or tidal waters; or
(2) The unusual and rapid accumulation or runoff of surface waters from any source.
"Flood control structure"means any structure or material, including but not limited to a berm, levee, dam or retaining wall, placed in areas where flooding occurs, and constructed for the purpose of protecting a structure, road, driveway, utility or transmission line.
"Flood damage-resistant materials"means any construction material capable of withstanding direct and prolonged contact with floodwaters without sustaining any damage that requires more than cosmetic repair.
"Flood fringe"means the area that is subject to the base flood outside of the floodway boundary.
"Flood hazard area"means special flood hazard area. See definition of special flood hazard area.
"Flood insurance rate map (FIRM)"means the official map of the County on which the Federal Emergency Management Agency has delineated both the special flood hazard areas and the risk premium zones applicable to the jurisdiction. For insurance purposes, the original FIRM date for Santa Cruz County is April 15, 1986.
"Flood insurance study (FIS)"means the official report provided by the Federal Emergency Management Agency that contains the Flood Insurance Rate Map, the water surface elevations of the base flood, and supporting technical data.
"Floodplain"means any land area susceptible to being inundated by water from any source. The base flood is used to define the floodplain by Federal agencies and the County of Santa Cruz.
"Floodplain Administrator"means the Planning Director or designee, who manages the administration and implementation of the National Flood Insurance Program regulations and the provisions of this chapter.
"Floodplain development permit"means a permit or document issued by the jurisdiction which authorizes performance of specific development activities located in a flood hazard area that are determined to be compliant with this chapter.

The analyses shall be prepared by a registered professional civil engineer using standard engineering methods and models.
"Freeboard"means a factor of safety usually expressed in feet above a base flood elevation or height for purposes of floodplain management. Freeboard is required to compensate for the many unknown factors that could contribute to flood heights or elevations greater than the height or elevation calculated for a selected size flood and floodway conditions, such as wave action, bridge openings, climate change, sea level rise, and the hydrological effect of urbanization of the watershed. Unless otherwise noted, freeboard shall be three feet in coastal high hazards areas and two feet in all other flood hazard areas.
