We constructed a network of stormwater "green streets" in Squirrel Hill to direct stormwater to recently improved infrastructure within Wightman Park. 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.
Progress & Status
The Phase II improvements took place within Solway Street, between Wightman St. and Murray Ave. and Negley Ave. between Solway Street and Woodmont Street. Improvements include:
- The connection of new green inlets
- Curbed stormwater planters
- Green intersection stormwater infrastructure treatments intended to capture and convey stormwater runoff to the park.
This results in a substantial expansion of stormwater captured and conveyed to the park, a 28.8‐acre project area in total.
In combination with the 1.48 impervious acres draining directly to the park, Phase II effectively captures the 1.5” storm runoff from 10.72 impervious acres and conveys it to the subsurface storage in Wightman Park, for a combined total capture of 12.20 impervious acres.
