For over a decade, restoration of this key ecological area in Pittsburgh has been taking place.
The Pittsburgh Parks Conservancy has been restoring Panther Hollow Watershed in Schenley Park for over 10 years. The Parks Conservancy, in partnership with Pittsburgh Water and Sewer Authority (PWSA) and the City of Pittsburgh, has recently expanded this project to also include Four Mile Run Watershed.
What's a watershed?
Understanding this critical area starts with a word: Watershed. A watershed is the total land area that drains into a particular body of water. Watersheds are interconnected, nested (contained) within one another, and their boundaries are their highest points.
The Four Mile Run Watershed encompasses the neighborhoods of Greenfield, Squirrel Hill, Oakland, and Hazelwood. The Panther Hollow Watershed is nested within the Four Mile Run Watershed.
Four Mile Run Watershed has changed drastically over the last century. Land once used for agriculture became neighborhoods and economic centers, while streams that fed Schenley Park were diverted underground. Over time, these changes caused more stormwater to enter our city's overburdened sewer system. This long-term restoration project aims to not only alleviate this stormwater issue, but to improve the health and aesthetics of Schenley Park.
For over a decade, the Pittsburgh Parks Conservancy, along with the Allegheny County Sanitary Authority (ALCOSAN), PWSA, and the City of Pittsburgh, have been nursing this ailing watershed back to health. A holistic, top-to-bottom plan includes projects such as large-scale tree plantings, erosion control, and the installation of green infrastructure.
Recent project updates
As part of the City Wide Green Infrastructure Plan, found here, restoring Panther Hollow Lake and recreating a stream through Junction Hollow was outlined as an ideal project for implementation. To ensure the best design possible we need your help. Please answer the questions about Panther Hollow and Junction Hollow to contribute to this project for Schenley Park.
First, read the documents that outlined the historic form on the landscape and then what is proposed in concept.
Then, go out to the park with the documents to envision the new park landscape or stay at your computer/phone.
- The Parks Conservancy has held two community walks to introduce park goers to preliminary designs and gather feedback about the needs of Panther Hollow Wetland and Lake as well as Junction Hollow. The final presentation will take place on September 20th, 2017 at St. John Chrysostom at 506 Saline Street, Pittsburgh, PA 15207. Please join us! Register here. If you cannot make it, we still welcome your feedback. Answer two surveys regarding Panther Hollow and Junction Hollow.
- PWSA releases City-Wide Green First Plan, a framework using green infrastructure in areas such as Four Mile Run Watershed to address stormwater issues. Read the plan here.
- The second in a series of community meetings on a concept plan for Four Mile Run was held. See what was presented at that meeting here.
- Retention grading at the Bob O'Connor Golf Course installed to soak stormwater into the ground when it rains.
- Meadow and infiltration trenches installed along Beacon Street. Based on data analysis and modeling through the University of Pittsburgh and Meliora Design, recommended trench improvements will be made by PWSA in 2017 to increase performance. Read the project update here.
