Floodplain or flood-prone area means any land area susceptible to being inundated by water from any source. See "Flood or flooding."
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.
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.
Flood Zone means areas having special flood hazards as described in the National Flood Insurance Act of 1968, as amended from time to time, and any successor statute.
Flood Hazard Boundary Map (FHBM) means an official map of a community, issued by the FEMA, where the boundaries of the Special Flood Hazard Areas have been defined as Zone A.
