About UpstreamPgh

Climate change is having an impact across the globe. Here, in our urban environment, these shifts are felt in our neighborhoods, parks and backyards. This is why we work to combat the effects of it, from managing excessive stormwater flows, to pollutants in our water, soil and air, and to connect each other with the environment to create positive change. From large green infrastructure projects that divert and infiltrate thousands of gallons of stormwater to residential projects that keep basements dry while providing beautiful native landscaping, UpstreamPgh has become the region’s leading resource for water management. Our heritage in Nine Mile Run, coupled with hundreds of projects via StormWorks, provides our community with hands-on, brains-on solutions.

In 2021, to recognize our proactive approach to stormwater problem-solving and its impact across the region, we became UpstreamPgh. Together, we are working to address the environmental problems that are happening in our communities by thinking, speaking and acting upstream. We invite you to join us.

What we do

We work to connect people with nature for a positive impact on the environment. From schoolchildren to municipal leaders, scientists to citizens, volunteers to homeowners, a healthy community starts with education, outreach and engagement.

Vision, Mission & Strategy
path next to stream


We envision a region with clean water accessible to all, healthy and resilient communities, and ecosystems restored to their natural functions.


We restore and protect our watershed ecosystem, while working regionally to support and implement resilient solutions for a healthier urban environment.


Our 2024-2028 Strategic Plan advances our people-first approach to watershed restoration to uplift climate justice and connect people with the natural environment.

We feel the urgency of this moment: the increasing impacts of climate change are compounded by long-running racial and economic disparities. The complex water-related problems facing our region require complex solutions. We must think, act, and be “upstream,” addressing problems at the source, with intentionality and care for the downstream implications.

The priorities outlined in the strategic plan include innovative stewardship, environmental justice, systemic response, creative engagement, and capacity-building. We are working at the intersection of people and place, connecting residents with the natural environment, co-developing solutions alongside communities, and advocating for systemic change.
