Zone AO definition

Zone AO means certain areas subject to one percent (1%) chance flooding in which base flood elevations range from one to three feet (1’ – 3’) above the "highest adjacent grade"; a clearly defined channel does not exist; the path of flooding is unpredictable and indeterminate; and velocity flow may be evident. If there is no depth number on the Flood Insurance Rate Map (FIRM) for Zone AO, the base flood elevation shall be two feet (2’) above the "highest adjacent grade." Where the Floodplain Administrator has knowledge that the one percent (1%) chance base flood elevation will be greater than two feet (2’) above the "highest adjacent grade", the Floodplain Administrator shall use that known one percent (1%) chance flood elevation in applying the provisions thereof. All the terms used in this Chapter and not defined in this Chapter shall be as defined in other Sections of this Title.
Zone AO means area of special flood hazards having shallow water depths and/or unpredictable flow paths between one (1) and three (3) feet. (Velocity flow may be evident; such flooding is characterized by ponding or sheet flow).

  • 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.
