or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which aze the minimum necessary to assure safe living conditions; or (B) any alteration of a "historic structure," provided that the alteration will not preclude the structure's continued designation as a "historic structure." [{lam] "Variance" means a grant of relief from the requirements of this chapter which pemvts construction in a manner that would otherwise be prohibited by this chapter. "Violation" means the failure of a structure or other development to be fully compliant with the community's flood plain management regulations. A structure or other development without the elevation certificate, other certifications, or other evidence of compliance with this chapter is presumed to be in violation until such time as that documentation is provided. [(§2)] "Water surface elevation" means the height, in relation to the National Geodetic Vertical Datum of 1929, (or other datum, where specified) of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas. "Watercourse" means a lake, river, creek, stream, wash, arroyo, channel, or other topographic feature on or over which waters flow at least periodically. Watercourse includes specifically designated areas in which substantial damage may occur. [(g4)] "Zone A" is the special flood hazazd azea that corresponds to the one-hundred- yeaz floodplains that are determined in the Flood Insurance Study by approximate methods. Because detailed hydraulic analyses aze not performed for such azeas, base flood elevations or depths have not been determined within this zone. "Zone AE" is the special flood hazazd azea that corresponds to the one-hundred- yeaz floodplains that are determined in the Flood Insurance Study by detailed methods. Whole-foot base flood elevations derived from the detailed hydraulic analyses have been determined at selected intervals within this zone. "Zone AH" is the special flood hazazd azea that conresponds to the azeas of one- hundred-year shallow flooding (usually azeas of ponding) where average depths are between one and three feet. Whole-foot base flood elevations derived from the detailed hydraulic analyses have been determined at selected intervals within this zone. "Zone AO" is the special flood hazard azea that corresponds to the azeas of one- hundred-yeaz shallow flooding (usually sheet flow on sloping terrain) where average depths are between one and three feet. Average whole-foot depths derived from the detailed hydraulic analyses have been determined within this zone. [(~8)] "Zone A99" is the special flood hazard azea where enough progress has been made on a protective system, such as dikes, dams, and levees, to consider it complete for insurance rating purposes. Base flood elevations have not been determined for areas designated as Zone A99. "Zone V" is the special flood hazazd azea that corresponds to the one-hundred- yeaz coastal floodplains extending from offshore to the inland limit of a primary frontal dune along an open coast and any other azea subject to high velocity wave action from storms or seismic sources. It is an azea subject to high velocity waters, including coastal and tidal inundation or tsunamis. Base flood elevations have not been determined for azeas designated as Zone V. "Zone VE" is the special flood hazazd azea that corresponds to the one-hundred- yeaz coastal floodplains extending from offshore to the inland limit of a primary frontal dune along an open coast and any other azea subject to high velocity wave action from 10
