Pittsburgh Flood Mitigation Planning 

Negley Run was identified in the Pittsburgh Water and Sewer Authority’s Strategic Plan for Stormwater as a priority watershed due to historic flooding that has resulted in damage and loss of life; vulnerability of neighborhoods within the watershed, such as Homewood, to reoccurring flooding; and opportunities for flood mitigation including availability of vacant and publicly owned land.

Our work for the watershed is addressing a new river outfall, constructed wetland systems, regenerative step pool conveyance systems, roadway elevation in coordination with the Pennsylvania Department of Transportation, sewer separation, and parallel storm relief sewers.

In a separate assignment, AKRF is leading the final design of a neighborhood-scale stormwater management and drainage improvement project to mitigate flooding issues impacting roadways and private properties in the Carrick neighborhood of Pittsburgh.
