In early December 2019 we began the construction of two green infrastructure projects that will help to manage stormwater within Four Mile Run. These engineered drainage channels, are being built in Schenley Park along Overlook Drive and next to the Bridle Trail.
Progress & Status
- Part of the larger Four Mile Run Stormwater Project, which encompasses Schenley Park and several Pittsburgh neighborhoods including Greenfield, Hazelwood, Oakland, Squirrel Hill, and the Run.
- Two drainage channels will help to capture rainwater, reduce erosion in the park, and slow down water running from the top of Schenley Park to Naylor Street in the Run.
- Drainage channels, also called detention swales, are shallow trenches with sides sloping towards the center that capture and direct rainwater. They create a path where water can flow.
- Before the projects, stormwater from this area was mostly unmanaged. It flowed off the steep hillside from Overlook Drive to the Bridle Trail below and further downhill, where it caused flooding. It also caused the combined sewer system to overflow into downstream neighborhoods and properties.
