Tres Rios Ecosystem Restoration and Flood Control Project

Phoenix, Arizona
 

Project reduces potential flooding by establishing wetlands and recreational areas along Phoenix-area rivers

HNTB served as design subcontractor on the design-build team for the Tres Rios Ecosystem Restoration and Flood Control project, which reclaims a 7-mile stretch of the Salt and Gila rivers west of Phoenix by establishing wetlands and recreational space.

HNTB experts developed a 3-D design contoured to the terrain, a process that took into consideration how the work would affect the open-water plain. As a result, the completed project reduces the potential 100-year floodwater level along the rivers.
