The special flood hazard areas identified by FEMA in a scientific and engineering report entitled "The Flood Insurance Study (FIS) for Maricopa County, Arizona and Incorporated Areas" dated September 30, 2005, with accompanying FIRMs dated September 30, 2005, and all subsequent amendments and/or revisions, are hereby adopted by reference and declared to be a part of this chapter. This FIS and attendant mapping is the minimum area of applicability of this chapter and may be supplemented by studies for other areas which allow implementation of this chapter and which are recommended to the Floodplain Administrator. The Floodplain Administrator, within its area of jurisdiction, will delineate (or may, by rule, require developers of land to delineate) for areas where development is ongoing or imminent, and thereafter as development becomes imminent, floodplains consistent with the criteria developed by FEMA and the Director of the Arizona Department of Water Resources. The FIS and FIRM panels are on file at City of Phoenix City Hall, 200 W. Washington Street, Phoenix, AZ 85003. (Ord. No. G-5707, 2012; Ord. No. G-6611, 2019; Ord. No. G-7116, § 2, 2023)
