Phase: Construction

The project includes channelization of existing wash (main branch) from Chandler Heights Road to Riggs Road along the existing alignment, and the east branch from Hawes Road to Crismon Road along Riggs Road. The total length of the project is approximately 3.5 miles. The channel will be earth-lined with rock slope protection with 4:1 to 8:1 side slopes and a 50-foot bottom width. The project will include multi-use components such as equestrian and pedestrian trails.

The 100-year project is anticipated to remove the existing floodplain extending from Chandler Heights Road to Riggs Road, which includes 71 acres of land and 68 properties. Queen Creek operates and maintains the facility.

Phase II will be implemented in two sub-phases. Phase IIA from Chandler Heights Road to Ellsworth Road was completed by the District in 2012 at a cost of $17.7 million. Phase IIB between Ellsworth Road and Crismon Road will be completed by the Town of Queen Creek in the future.


Project Phase IIA was completed between Chandler Heights Road and Ellsworth Road in June 2012. The Town of Queen Creek started Construction of Phase IIB, between Ellsworth Road and Crismon Road, in December 2017.
