On June 11, 2026, Pittsburgh Water approved a $6.76 million construction contract for a joint project with the City of Pittsburgh aimed at reducing neighborhood flooding in Carrick and Overbrook. The Pittsburgh Flood Project, formally identified in city materials as the Stewart Avenue Stormwater Improvements Project, is in its construction window as of August 28, 2026, with work expected to run through September 2027, according to the City of Pittsburgh announcement.
The investment has been described publicly as a $6.8 million effort to reduce flooding and improve stormwater management in two South Pittsburgh neighborhoods, with CBS Pittsburgh reporting on the planned upgrades for Carrick and Overbrook. The work matters to residents because recurring street flooding can affect homes, sidewalks, travel routes, and emergency access during heavy rain. For a civic project of this length, the main questions are practical: where the work is concentrated, what infrastructure is being replaced or added, who is paying for each part, and how residents can follow public updates while construction continues.

In Pittsburgh, the public agencies leading this effort are the City of Pittsburgh and Pittsburgh Water, and the project area is centered on streets that feed into the Saw Mill Run watershed.
What The Pittsburgh Flood Project Covers
June 11 Approval
The June 11 approval by Pittsburgh Water moved the joint city-water authority effort from planning toward construction. The public materials identify the project as a coordinated investment rather than a single-purpose paving job. Its stated purpose is to reduce recurring localized flooding, improve stormwater management, and keep water off streets and away from homes during heavy rainfall.
That distinction is significant for Carrick and Overbrook residents because the project joins underground drainage work with surface improvements. New stormwater infrastructure can change how runoff moves through the neighborhood, while roadway and sidewalk work can address conditions residents encounter at street level. The city’s description links the project to the Saw Mill Run watershed, which makes the effort part of a broader drainage concern rather than only a block-by-block repair.
Pittsburgh Flood Project Timeline
The Pittsburgh Flood Project was expected to begin construction in July 2026 and conclude in September 2027. Because today is August 28, 2026, the project should be treated as an active, multi-month construction effort rather than an upcoming announcement. The long timeline also means residents may see different phases of work at different points along Stewart Avenue and nearby streets before the fall 2027 completion target.
Public infrastructure schedules can shift because of weather, utility conflicts, material needs, or field conditions uncovered after work begins. The available official information supports the construction window and the planned scope, but it does not provide a street-by-street daily schedule in the research materials supplied here. Residents should rely on City of Pittsburgh and Pittsburgh Water notices for any specific lane, sidewalk, parking, or access changes tied to active construction days.
Where Work Is Focused
Stewart Avenue And Side Streets
The named work area includes Stewart Avenue between Saw Mill Run Boulevard and Parkdale Street. The project also includes parts of Parkdale Street, Esther Way, Horning Street, and Carol Circle. These are the locations residents should watch most closely for construction staging, posted restrictions, and field activity connected to stormwater upgrades.
Stewart Avenue’s connection to Saw Mill Run Boulevard makes the corridor especially relevant for drivers and nearby households. Saw Mill Run Boulevard is a major route through the area, and side-street drainage issues can affect how water moves toward larger roadways and lower-lying areas. The project’s focus on both main and side streets reflects the way neighborhood flooding often depends on a connected drainage system, not only on one visible trouble spot.
Stormwater Work And Street Repairs
The official project description lists several major components:
- Installation of a new storm sewer system.
- New catch basins and manholes.
- Green infrastructure elements.
- Roadway and sidewalk improvements.
Catch basins and storm sewers are central to moving rainwater off streets. Manholes provide access for inspection and maintenance. Green infrastructure can help manage runoff closer to where rain falls, depending on the specific design used at each location. Roadway and sidewalk work can restore public space affected by underground construction and may improve everyday travel conditions after utility work is complete.
How The Partnership Is Funded
Shared Responsibilities
The funding split is described by project partners in a clear way: Pittsburgh Water is responsible for storm sewer and green infrastructure work, while the City of Pittsburgh is responsible for roadway and sidewalk improvements. Other project costs are to be shared equally. That structure matters because it shows how the project crosses agency responsibilities. Stormwater systems, streets, and sidewalks may be experienced by residents as one neighborhood problem during heavy rain, but they often fall under different public functions.
For taxpayers and ratepayers, the division of responsibility is a key accountability point. Residents can ask which agency is responsible for a given portion of the work if questions arise about construction sequencing, restoration, or maintenance after completion. Clear responsibility also helps public officials explain how funds are being used and why a joint agreement was needed for a project that includes both water management and transportation-related repairs.
Why The Watershed Matters
The project is tied to stormwater management in the Saw Mill Run watershed. A watershed-based approach recognizes that rainfall does not follow neighborhood borders. Water flows according to grade, drainage paths, pipes, inlets, and stream systems. Work in Carrick and Overbrook can be relevant not only for the blocks named in the project area, but also for how runoff is handled as it moves through the larger drainage network.
The stated goal is not to eliminate every possible water problem during every storm. The supported claim is narrower and more specific: the work aims to reduce recurring localized flooding, keep water off streets and away from homes during heavy rain, and improve stormwater management. That is the standard residents should use when reviewing progress and asking questions during the construction period.
Resident Impacts And Civic Follow-Up

How Residents Can Track Notices
Residents along Stewart Avenue, Parkdale Street, Esther Way, Horning Street, and Carol Circle have the strongest reason to monitor project notices. People who drive through the corridor or use nearby sidewalks should also pay attention, since the planned work includes roadway and sidewalk improvements. The research available for this report does not include a full traffic-control plan, so any claim about closures, detours, or parking restrictions would be premature without a posted agency notice.
The safest civic step is to follow official communications from the City of Pittsburgh and Pittsburgh Water during the active construction period. Residents can also raise practical questions through neighborhood meetings, public comment opportunities, or direct agency contact if notices identify a specific issue. Useful questions include when work will reach a block, how access will be maintained, how sidewalks will be restored, and how stormwater features will be maintained after construction.
Why The Schedule Matters
A July 2026 to September 2027 construction window means the project spans more than one heavy-rain period. That timing may test how temporary construction conditions and existing drainage patterns interact before the full system is complete. It also gives residents time to document recurring issues and communicate them to the responsible agencies while crews are still working in the area.
For local government, the schedule creates a public accountability period. The agencies have identified the project area, purpose, major components, and cost-sharing structure. As the work continues, residents can compare field conditions with those public commitments. That kind of civic follow-up is especially important for stormwater projects, where many of the most expensive improvements are underground and may not be obvious once streets are restored.
Civic Takeaways From The Pittsburgh Flood Project
The Pittsburgh Flood Project is a targeted public works effort in Carrick and Overbrook, approved on June 11, 2026, with construction expected to continue through September 2027. Its core work includes storm sewers, catch basins, manholes, green infrastructure, road repairs, and sidewalk improvements in a defined set of streets near Stewart Avenue and Saw Mill Run Boulevard.
The project’s civic importance rests in its practical promise: reducing repeated localized flooding and moving stormwater away from streets and homes during heavy rain. The public should judge the work by that stated purpose, the published schedule, and the responsibilities assigned to Pittsburgh Water and the City of Pittsburgh. For residents, the next step is steady attention to official notices and clear reporting of site-specific concerns while the work remains active.
