Pittsburgh, PA - The Pittsburgh Water and Sewer Authority (PWSA) is mobilizing construction crews from Frank J. Zottola Construction, Inc. to begin stormwater infrastructure renovations on portions of Wightman Street, Solway Street, S Negley Avenue, Woodmont Street, and Murray Avenue in Squirrel Hill. 

These improvements include the addition of curbed stormwater bumpout planters at intersections, channel drains that convey stormwater under the street between planters, and upgraded sewer inlets. This new network of stormwater "green streets" will capture and direct stormwater to recently improved infrastructure within Wightman Park while enhancing pedestrian safety at intersections.

During Phase One of the Wightman Park Stormwater Project, PWSA partnered with the City of Pittsburgh to construct stormwater storage facilities within and underneath the renovated park. The construction of these Phase Two street retrofits will maximize the park’s new stormwater management capabilities. Together, the overall Wightman Park Stormwater Project will help reduce overflows of combined stormwater and sewage into the Monongahela River, flooding in the park, and basement sewage backups in the neighborhood. Partial funding for both phases of the Wightman Park project was provided by the Allegheny County Sanitary Authority (ALCOSAN) Green Revitalization of Our Waterways (GROW) grant program.
