We need you - Philadelphia’s residents and civic and community leaders - to get involved and speak up to make Green Stormwater Infrastructure successful.

What is Green Stormwater Infrastructure (GSI)?

• Green Stormwater Infrastructure is a nature-based solution to water quality issues that urban stormwater runoff causes and provides greater benefits than conventional (or “Gray”) stormwater solutions. 

Why do we need Green Stormwater Infrastructure?

• Stormwater — surface water generated during a rainstorm or when snow melts — runs off roads, parking lots, and roofs, picking up oil, dirt, and other pollutants as it makes its way to storm drains. Sixty percent of Philadelphia’s storm drain system is a combined system that mixes with household wastewater. Most large storms cause untreated sewage to overflow directly into local rivers and creeks.
• GSI tools reduce pollution and flooding events by naturally slowing and filtering rainwater before entering the stormwater system.

The Economic, Social, and Environmental Benefits in your Neighborhood

• GSI creates jobs and strengthens the economy. If we increase reliance on GSI, we can expect an additional 1,000 jobs per year and $2 million per year in local tax revenues over the next 25 years.
• GSI reduces crime and blight, improves public health, and enhances recreation.
• GSI mitigates the impacts of climate change by creating a localized cooling effect.
• GSI helps keep rivers and streams clean enough to fish, boat, and swim.

How is Green Stormwater Infrastructure already being used in Philadelphia?

• In 2011, Philadelphia began implementing a plan called Green City, Clean Waters to reduce stormwater pollution by focusing on green practices. In only 8 years, 948 public and private GSI projects have been constructed in Philadelphia. This means that rainfall on 679 acres is managed with GSI.
• The expansion of GSI in Philadelphia has created 92 acres of new or improved green and open space, creating vibrant communities with spaces to recreate.

Without Green Stormwater Infrastructure, we could see:

• Philadelphia lose its status as a national GSI leader.
• Fewer green-economy jobs.
• Worsening river and creek health for fishing, boating, and swimming.
• Hotter temperatures and poorer air quality as climate change intensifies.
