Four Mile Run Stormwater Project

In Planning Stormwater

The Four Mile Run Watershed encompasses Schenley Park and several Pittsburgh neighborhoods including Greefield, Hazelwood, Oakland, and Squirrel Hill. After a lengthy review process with State regulators, PWSA will pursue the design of a stormwater only pipeline in The Run neighborhood, located in the basin of the watershed. This project will help to reduce basement backups and neighborhood flooding that many residents in The Run have experienced.

Progress & Status

Design Complete

The construction of a stormwater only pipeline will help to alleviate flooding and basement backups and will convey stormwater from The Run neighborhood to the Monongahela River. PWSA plans to initiate the design of this project in 2023. 

PWSA received 90% design drawings during the summer of 2023 and completed a constructability analysis. We initiated an additional investigation to better understand potential conflicts with existing underground utilities. We anticipate completing the investigation in January 2024, the results will provide a better understanding of how to move the project forward to construction. 

PWSA remains committed to the construction and installation of green infrastructure projects within the Four Mile Run Watershed and throughout Pittsburgh. These project components for Four Mile Run will be phased in at a later time. To review past information about the initial plans for the Four Mile Run Stormwater Project, please visit
