We are constructing a network of stormwater "green streets" in Squirrel Hill to direct stormwater to recently improved infrastructure within Wightman Park.
Progress & Status
This project is located within the M-29 sewershed, also known as the Four Mile Run watershed. By capturing and managing stormwater, this project aims to reduce overflows of combined stormwater and sewage into the Monongahela River, flooding in the park, and basement sewage backups in the neighborhood.
- Stormwater retrofits on portions of Wightman Street, Woodmont Street, Negley Avenue, Solway Street, and Murray Avenue will capture and direct stormwater to the park while also enhancing pedestrian safety at intersections.
- The stormwater retrofits include the addition of curbed stormwater "bumpout" planters at intersections, channel drains that convey stormwater under the street between planters, and upgraded sewer inlets.
Wightman Park Stormwater Project: Phase Two
Special Notice June 23 - 25: To complete the sidewalk located next to the stormwater bumpout, the contractor will pour concrete in the alley behind the 1300 block of South Negley Avenue and Solway Street, from Wednesday, June 23 through Friday, June 25.
Those using the garages are encouraged to move their cars and use available street parking in the neighborhood. We apologize for this inconvenience. This work was originally scheduled to take place last week, but was postponed.
Weeks of June 14 and 21
The contractor is concentrating work at the intersections of Solway Street and South Negley Avenue and Solway Street and Murray Avenue. Construction activity at these locations include:
Solway Street and S. Negley Avenue
- Forming and pouring planter walls and curbs at the north side of Solway Street
- Pouring sidewalks and portions of the stormwater system that will help to filter sediment and retain water at the north side of Solway Street
Solway Street and Murray Avenue
- Installing new storm inlets and manholes
- Duquesne Light and Peoples Gas will be onsite during the week of June 14 to continue relocation of street poles and gas lines
*Schedule could change due to weather, unforeseen site conditions, etc.
