Green stormwater infrastructure

By 2035, increase by 600 acres the amount of green stormwater infrastructure installed.

Green stormwater infrastructure (GSI) addresses community greening and cooling, reduces flood risk, and improves water quality through the installation of trees, rain gardens, green roofs, and a variety of basins, wetlands, and other low-lying terrain features that capture and manage rainfall and runoff. It is a proven approach for communities vulnerable to climate-related stresses tied to rising temperatures and severe flood risks.

Through 2036, the City of Philadelphia is obligated to spend more than $1 billion on additional stormwater infrastructure improvements as part of its obligations under the U.S. Clean Water Act. These are public dollars, funded by residents’ water bills. The blueprint for this work is Philadelphia’s Green Cities Clean Waters plan, which is held up as a national model. There is great opportunity to ensure the plan and this massive public investment maximize community greening and climate resilience and yield equitable benefits for the communities most in need.

Given this continued public investment and the benefits of green stormwater infrastructure, we have focused on increasing the amount of GSI installed in Philadelphia.

We recognize that there are many ways that organizations and communities can contribute to advancing this objective and are looking for Philadelphians’ best ideas about how to accomplish this across the city. We are especially interested in supporting work in neighborhoods with the greatest needs and most well-positioned to welcome and capitalize on the multiple positive impacts of GSI.

We measure progress for this objective via grantee reporting on the acreage of GSI projects that have been created.
