Geologic Floodplain definition

Geologic Floodplain means that portion of the land that has, in the recent geologic past, been subject to fluvial processes. The geologic floodplain may be different than the Areas of Special Flood Hazard or Special Flood Hazard Areas. Where a detailed hydrologic and hydraulic analysis has not been conducted by an Arizona Registered Professional Engineer, utilizing accepted engineering practices, and accepted by the Floodplain Administrator, the Geologic Floodplain shall be the Regulatory Floodplain.

Geologic Floodplain means those lands adjacent to a watercourse that have been subject to fluvial processes during the Holocene epoch (i.e., approximately the past 10,000 years). The geologic floodplain may be different from the regulatory floodplain. (Ord. 2010 FC-1; Ord. 1999 FC-1 § 1 (part), 1999; Ord. 1988 FC-2 Art. 4 (part), 1988)

Related to Geologic Floodplain

  • Floodplain or "Flood-prone area" means any land area susceptible to being inundated by water from any source (see definition of "Flooding").

  • Floodway means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height.

  • Floodplain or flood-prone area means any land area susceptible to being inundated by water from any source (see definition of “flood”).

  • Water surface elevation means the height, in relation to the National Geodetic Vertical Datum (NGVD) of 1929, the North American Vertical Datum (NAVD) of 1988, or other datum, where specified, of floods of various magnitudes and frequencies in the floodplains of riverine areas.

  • Surface water means all water which is open to the atmosphere and subject to surface runoff.

  • Soil means all unconsolidated mineral and organic material of any origin.

  • Floodplain Management means the operation of an overall program of corrective and preventive measures for reducing flood damage, including but not limited to emergency preparedness plans, flood control works and floodplain management regulations.

  • Groundwater means all water, which is below the surface of the ground in the saturation zone and in direct contact with the ground or subsoil.

  • Area of shallow flooding means a designated AO or AH Zone on a community's Flood Insurance Rate Map (FIRM) with one percent or greater annual chance of flooding to an average depth of one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and indeterminate; and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow.

  • Flooding means a volume of water that is too great to be confined within the banks or walls of the stream, water body or conveyance system and that overflows onto adjacent lands, thereby causing or threatening damage.

  • mining area means all those pieces of land containing two hundred and forty‑six (246) square miles or thereabouts situate in what is known to the parties as the “Xxx Xxxxx‑Siberia Nickel Laterite Area” the subject of the mineral claims applications for mineral claims and Temporary Reserves listed in the First Schedule hereto which are generally delineated and respectively coloured green and orange and red in the plan marked “X” signed by or on behalf of the parties for the purpose of identification;

  • Floodproofing means any combination of structural and nonstructural additions, changes, or adjustments to structures which reduce or eliminate flood damage to real estate or improved real property, water and sanitation facilities, structures, and their contents.

  • Drainage area means a geographic area within which stormwater, sediments, or dissolved materials drain to a particular receiving waterbody or to a particular point along a receiving waterbody.
