Wightman Park Stormwater Project: Phase Two

In Construction Stormwater

We are constructing a network of stormwater "green streets" in Squirrel Hill to direct stormwater to recently improved infrastructure within Wightman Park. 

Progress & Status

Construction Complete

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. 

Improvements Include

  • 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.
