"Violatio~i' means the failure of a structure or otrier decetopment to he <br /> fiill~~ compliant with the conunwiitv~s tloodplain management regulations. A <br /> structure or other development ~iithout the elevation certiticate, other <br /> certifications. or other evidence of compliance with this chapter is presumed to he <br /> h~ violation until such time as that documentation is pro~•ided. <br /> [(-6?IJ "Water surface elevation" means the height, in relation to the National <br /> Geodetic Vertical Datum of 1929, (or other datum, where specified) of floods of <br /> various magnitudes and frequencies in the floodplains of coastal or riverine azeas. <br /> "Watercourse" means a lake, river, creek, stream, wash, arroyo, channel, <br /> or other topographic feature on or over which waters flow at least periodically. <br /> Watercourse includes specifically designated azeas in which substantial damage <br /> may occur. <br /> [(-64-1] "Zone A" is the special flood hazard area that conresponds to the <br /> one-hundred-year floodplains that are determined in the Flood Insurance Study by <br /> approximate methods. Because detailed hydraulic analyses are not performed for <br /> such areas, base flood elevations or depths have not been determined within this <br /> zone. <br /> [(63-1] "Zone AE" is the special flood hazard area that corresponds to the <br /> one-hundred-year floodplains that are determined in the Flood Insurance Study by <br /> detailed methods. Whole-foot base flood elevations derived from the detailed <br /> hydraulic analyses have been determined at selected intervals within this zone. <br /> L4661] "Zone AH" is the special flood hazard area that corresponds to the azeas of <br /> one-hundred-year shallow flooding (usually areas of ponding) where average <br /> depths are between one and three feet. Whole-foot base flood elevations derived <br /> from the detailed hydraulic analyses have been determined at selected intervals <br /> within this zone. <br /> [E6~11 "Zone AO" is the special flood hazazd azea that corresponds to the areas of <br /> one-hundred-year shallow flooding (usually sheet flow on sloping terrain) where <br /> average depths are between one and three feet. Average whole-foot depths <br /> derived from the detailed hydraulic analyses have been determined within this <br /> zone. <br /> [(6511 "Zone A99" is the special flood hazard azea where enough progress has <br /> been made on a protective system, such as dikes, dams, and levees, to consider it <br /> complete for insurance rating purposes. Base flood elevations have not been <br /> determined for azeas designated as Zone A99. <br /> [(69}] "Zone V" is the special flood hazard area that corresponds to the <br /> one-hundred-yeaz coastal floodplains extending from offshore to the inland limit <br /> <br /> of a primary frontal dune along an open coast and any other area subject to high <br /> velocity wave action from storms or seismic sources. It is an area subject to high <br /> velocity waters, including coastal and tidal inundation or tsunamis. Base flood <br /> elevations have not been determined for azeas designated as Zone V. <br /> [(~91] "Zone VE" is the special flood hazard area that corresponds to the <br /> one-hundred-year coastal floodplains extending from offshore to the inland limit <br /> of a primary frontal dune along an open coast and any other azea subject to high <br /> velocity wave action from storms or seismic sources. It is an area subject to high <br /> velocity waters, including coastal and tidal inundation or tsunamis. Whole-foot <br /> 11 <br /> <br />
