Pine Creek is a major developed watershed in Allegheny County that regularly experiences flooding. The Pine Creek Watershed Coalition is an organization of stakeholders, intent on improving the health of the watershed.

The GSA advocated for the protection and enhancement of open space from 1992-2012. Groundbreaking research documenting the economic value of open space, Return on the Environment  was published in 2011.

An educational tool, the Watershed Atlas of the Monongahela and Allegheny Rivers is an online outlet—created in 1999—to educate residents on Western PA watersheds.
