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)
