Fans 5 & 6 Redelineation Study:

One conclusion from the PPW ADMS was that the floodplains known as Fans 5 & 6 should be remapped to better depict the current flood hazards. The Flood Control District developed new floodplain maps for Fans 5 & 6, which were shared with the affected property owners at two open houses in September 2016. As a result of the public outreach, the Flood control District received new technical information from several property owners that was incorporated into the floodplain study. The Flood Control District submitted the proposed floodplain maps to FEMA for their review March 2017. FEMA reviewers are in the process of reviewing the hydrology and hydraulics models that were used to develop the proposed floodplain maps.

Rawhide Wash Flood Hazard Mitigation Study:

During 2016 and 2017, the Flood Control District met with the City of Phoenix, City of Scottsdale, and other stakeholders to discuss the alternatives, preliminary cost estimates, and expected benefits of the project when constructed. Based on these discussions, the Flood Control District along with the City of Phoenix and City of Scottsdale are moving forward with pre-design activities for the project. Additional public outreach is planned for Winter 2017 and in 2018.

Model Results


The overall study was completed in June 2016, however, work continues on the Fans 5 & 6 Floodplain Redelineation Study and the Rawhide Wash Flood Hazard Mitigation study.
