Project Type: Study

Project Description:

The District is conducting a study which will result in revisions to the Hassayampa River floodplain/floodway in unincorporated Maricopa County and the City of Buckeye. The floodplain to be studied is approximately 14.5 linear miles from Jackrabbit Wash to the confluence with the Gila River. 

The District conducts floodplain and floodway delineation studies to identify and refine areas that are subject to inundation by a 100-year flood (one percent chance of occurring in any year).

The study is within Township 2 North, Range 5 West, Sections 22, 23, 26, 27, and 34, Township 1 North, Range 5 West, Sections 3, 10, 15, 22, 23, 26, 27 and 35, Township 1 South, Range 5 West, Sections 1, 2, 11, 12, 13, 14, 23, 24, 25 and 26, and Township 1 South, Range 4 West, Sections 7, 17, 18, 19, 20 and 30.  

Once the study is complete, impacted property owners will be notified and be able to review the results online. The results will be used by the City of Buckeye and unincorporated Maricopa County to regulate development within the floodplain.  The study will be submitted to FEMA for updating their Flood Insurance Rate Maps.
