This is a re-study of the effective Special Flood Hazard Area (SFHA) for Centennial Wash in western Maricopa County from its confluence with the Gila River to the boundary between La Paz and Maricopa counties. The effective SFHA was delineated in 1989 by Cella Barr and Associates. This re-study is being performed because the hydrology has been updated due to the inclusion of 20 additional years of gage record. FEMA has approved the updated hydrology via a CLOMR, case number 12-09-0043R, which was submitted by RBF Consulting and CV Harquahala, LLC.


The District has incorporated the new floodplain from this study onto its pending floodplain layer in order to regulate to it. The study is at FEMA for review and will be prioritized for inclusion onto the Federal Insurance Rate Maps.
