City of Pittsburgh and Pittsburgh Water Partner to Advance $6.8 Million Project to Reduce Flooding in Carrick and Overbrook
Joint infrastructure project will reduce flooding risks, improve roadways, and strengthen stormwater management along Stewart Avenue and nearby streets.
Pittsburgh, PA – Pittsburgh Water and the City of Pittsburgh are moving forward with a major infrastructure project designed to address longstanding flooding concerns in the Carrick and Overbrook neighborhoods.
“When residents raise concerns about flooding, they deserve solutions that address the root causes of the problem,” said Pittsburgh Mayor Corey O’Connor. “By partnering with Pittsburgh Water on this project, we’re improving roads and sidewalks, reducing flooding risks, and investing in infrastructure that will benefit Carrick and Overbrook residents for years to come.”
Pittsburgh Water approved a $6.76 million construction contract for the Stewart Avenue Stormwater Improvements Project, as well as a cost-share agreement with the City of Pittsburgh to support the work. Construction is expected to begin in July 2026 and end in September 2027.
The project will install a new storm sewer system, catch basins, manholes, green infrastructure, and roadway improvements along Stewart Avenue and nearby streets. Together, these improvements will help reduce localized flooding, improve stormwater management, and enhance neighborhood infrastructure.
“Managing stormwater is an essential part of Pittsburgh Water’s commitment to building a more resilient community,” said Pittsburgh Water CEO Will Pickering. “For years, residents in this area have experienced flooding that threatened homes, impacted roadways, and created ongoing challenges during heavy rain events. By installing new stormwater infrastructure and green infrastructure, this project will help keep water off streets and away from homes while improving how stormwater is managed throughout the neighborhood. We’re proud to partner with the City of Pittsburgh to deliver these improvements for residents.”
Today, much of the stormwater in the area flows overland during heavy rain events, traveling along roadways and toward nearby properties. The project will create a dedicated system of storm sewers and catch basins designed to capture runoff and safely carry it away, helping keep water off streets and away from homes.
In addition to traditional stormwater infrastructure, the project includes a green infrastructure facility designed to capture and temporarily store stormwater before slowly releasing it into the system. By slowing runoff and reducing peak flows, the facility will help alleviate pressure on local infrastructure and reduce the rate of stormwater entering the Saw Mill Run watershed during rain events.
The project will take place along Stewart Avenue between Saw Mill Run Boulevard and Parkdale Street, as well as portions of Parkdale Street, Esther Way, Horning Street, and Carol Circle.
Because the flooding issues in this area stem from multiple infrastructure challenges, Pittsburgh Water and the City of Pittsburgh developed the project as a partnership. Pittsburgh Water will fund storm sewer and green infrastructure improvements, the City will fund roadway and sidewalk improvements, and other project costs will be shared equally.
During construction, traffic will be maintained with flaggers and temporary lane restrictions. Additional construction and traffic information will be shared with residents before work begins.
