The Four Mile Run Stormwater Project encompasses Schenley Park and several Pittsburgh neighborhoods including Garfield, Hazelwood, Oakland, and Squirrel Hill. This project will capture and route stormwater through a natural channel that will follow the path of the historic streams that formed Four Mile Run from Panther Hollow Lake to the Monongahela River. It will help to reduce combined sewer overflows, basement backups, and neighborhood flooding.
Progress & Status
Early Action projects along Overlook Drive and the Bridle Trail are underway.
Panther Hollow Lake
- Stormwater improvements to Panther Hollow Lake will enable us to manage the depth of the lake and control the volume of water entering the combined sewer system.
- The State Department of Environmental Protection (DEP) is requiring a dam permit for the lake.
- We are working to obtain the necessary permits and meet safety regulations.
Junction Hollow: Stormwater improvements will follow the path of the former Junction Hollow Stream. This portion of the project will channel rainwater, restore streambanks, and plant native and climate tolerant vegetation.
Connection to the River: We are evaluating a series of options to convey stormwater from Schenley Park and the Run to the Monongahela River.
