Citizens of Scottsdale and Maricopa County will benefit from enhanced, flood protection along Granite Reef Wash as the Flood Control District (FCD) and City of Scottsdale (City) partner to expand the storm drain systems in southeast Scottsdale. The Maricopa County Board of Supervisors has approved an Intergovernmental Agreement (IGA) allowing for construction of the first phase of the Granite Reef Wash Drainage Improvement Project to reduce effects of a 100-year storm.
Construction of the storm drains will occur from McDonald Drive to Camelback Road and Granite Reef Road to Pima Road. Drainage improvements will include storm drains and inlet features with water taken to Indian Bend Wash. The estimated project cost associated with this IGA is $6.6 million with cost-sharing at 50%/50%.
"One thousand, eighty-one residential and commercial properties are located within this floodplain," explained Supervisor Steve Chucri, District 2. "I am pleased these improvements will help protect our citizens. This agreement serves as a good example of collaboration between local governments in the best interest of our shared constituents."
The resulting increase in stormwater collection and re-directed flow will reduce drainage concerns for area residents.
"This is a much needed project that will provide relief from disruptive and damaging floods for many residents in Scottsdale," said Scottsdale Mayor W.J. ‘Jim’ Lane. "We are looking forward to its completion and appreciate the partnership with the Flood Control District of Maricopa County that is helping to make it happen. I also want to thank the Salt River Pima-Maricopa Indian Community, who is partnering with Scottsdale on our portion. Their participation is integral to the success of this project."
Once completed, the overall project will remove approximately 700 residences from the floodplain and save property owners money on flood insurance. Construction is expected to start this fall.
"The Flood Control District’s goal is to reduce flooding risk to residents and property," said FCD Chief Engineer and General Manager, Bill Wiley. "This project gives us the opportunity to do just that."
