Tidal Flood Hazard Area means a flood hazard area in which the flood elevation resulting from the two-, 10-, or 100-year storm, as applicable, is governed by tidal flooding from the Atlantic Ocean. Flooding in a tidal flood hazard area may be contributed to, or influenced by, stormwater runoff from inland areas, but the depth of flooding generated by the tidal rise and fall of the Atlantic Ocean is greater than flooding from any fluvial sources. In some situations, depending upon the extent of the storm surge from a particular storm event, a flood hazard area may be tidal in the 100-year storm, but fluvial in more frequent storm events.
Flood hazard area means any area subject to inundation by the base flood or risk from channel migration including, but not limited to, an aquatic area, wetland, or closed depression.
Special Flood Hazard Area means an area that FEMA’s current flood maps indicate has at least a one percent (1%) chance of a flood equal to or exceeding the base flood elevation (a 100-year flood) in any given year.
Floodplain or flood-prone area means any land area susceptible to being inundated by water from any source. See "Flood or flooding."
Area of special flood hazard means the land in the floodplain within a community subject to a one percent or greater chance of flooding in any given year.
