This area flows to the A-42 Sewershed; one of the largest sewersheds and highest combined sewer overflow contributors in Pittsburgh to the rivers. This project aims to manage runoff from 12 impervious acres in the surrounding area.

Stormwater Solutions

• Gravel stormwater storage under the center medians of Thomas and McPherson Boulevards
• Permeable paver parking lanes along North Linden Avenue with underground gravel stormwater storage
• Gravel stormwater storage under the road along North Dallas Avenue
• Permeable paver "green alley" with underground gravel stormwater storage in Starling Way

Water Main Improvements

• Replaced the existing water mains along McPherson Boulevard between Fifth Avenue and North Dallas Avenue and along North Linden Avenue between McPherson Boulevard and Thomas Boulevard.
• Also replaced all public service lines and any private lead service lines connected to those water mains.
• By coordinating the stormwater, water main replacement, and lead service line replacement projects, we minimized disruptions and more efficiently managed costs.
