When it rains, stormwater travels from the park through our combined sewer system to ALCOSAN and overflows into the Monongahela River. Typical storm events frequently cause these pipes to overflow into the river impacting local water quality. Future stormwater solutions align with the goals of the City of Pittsburgh’s South Side Park Master Plan.

The goals of the project are to:

• Reduce combined sewer overflows into the river
• Reduce basement backups
• Slow down the flow of stormwater from higher elevation areas

Coordination with individual property owners is needed to understand conditions related to basement backups and possible neighborhood flooding. 

Park Construction Phasing

• Phase 1A: will include stormwater project components uphill of the Serpentine Steps.
• Phase 1B: will include stormwater project components downhill of the Serpentine Steps.
