Green City, Clean Waters Five-Year Accomplishments
In the first five years of Green City, Clean Waters, the nation's largest green stormwater infrastructure program, Philadelphia added thousands of green stormwater tools to our neighborhoods through development, redevelopment and investments at hundreds of private and public sites, keeping hundreds of millions of gallons of polluted water out of our rivers annually.

Since 2011, we have been working to create a complex, efficient machine that relies on modeling, planning, design, engineering, outreach, monitoring and maintenance to create a network of green infrastructure tools that’s unlike anything done before in the U.S.

As of June 1, 2016, the City has gained 837.7 Greened Acres, a feat that means we are now keeping more than 1.5 billion gallons of polluted water out of our rivers during a typical year of rainfall in Philadelphia.

In addition to protecting our rivers, we are making our neighborhoods greener, more vibrant places to live, learn, work and play. Learn more at
