DEAR COLLEAGUES: In the summer of 2014, the Institute of Politics Infrastructure Policy Committee determined it was necessary to do a report Southwestern Pennsylvania is endowed with an abundance on the status of green infrastructure initiatives in the region. of some of the freshest and cleanest water in the country. The committee was interested in examining the benefits of However, while this abundance allows our region to reliably green infrastructure, especially related to water management, fulfill all of our water needs, it also places a greater burden as well as the economic, social, and environmental benefits on us to responsibly handle this resource. derived from green infrastructure installation. Additionally, the committee wanted to further understand the challenges Since the passage of the 1972 Clean Water Act, our region and barriers associated with green infrastructure expansion and many across the country have made tremendous progress in the region, primarily related to design, maintenance, cost, in protecting precious water resources, making them the and requirements of installation. safest and cleanest possible. However, in light of frequent wet weather events, aging sewer infrastructure, and changes After months of background research on green infrastructure in our region’s land use development, Southwestern designs and interviews with a variety of stakeholders working Pennsylvania still has a long way to go in order to meet on green infrastructure-related initiatives in the region, the full environmental compliance. committee reached consensus on a variety of recommendations for the region moving forward.

Meanwhile, green infrastructure initiatives have gained popularity across the nation as regions increasingly face these types of complicated problems related to providing clean, reliable water for drinking and recreational activities. Green infrastructure is seen as a sustainable approach to water management that can mitigate many of the impacts that wet weather events cause. These types of infrastructure initiatives can help to divert excess stormwater from entering streams, rivers, or the sewer system. 2 GREEN INFRASTRUCTURE STATUS REPORT UNIVERSITY OF PITTSBURGH INSTITUTE OF POLITICS INFRASTRUCTURE POLICY COMMITTEE Stan Caldwell Paul Messineo Executive Director, Traffic21 Institute Business Development Manager Carnegie Mellon University Allen & Shariff Engineering H.
