Description
William Penn Foundation’s Green Stormwater Infrastructure objective, within its Environment and Public Space program, aims to increase installed green stormwater infrastructure by 600 acres by 2035. It supports stormwater solutions using vegetation, infiltration, and landscape treatments, including trees, rain gardens, green roofs, naturalized basins, and wetlands. These approaches capture rainfall and runoff while improving water quality, reducing flood risk, and supporting community cooling and greening.
The Foundation welcomes capital improvements, outreach and education, training and technical assistance, policy advocacy, system change, and other approaches that advance this objective. Work may focus on a neighborhood or operate citywide. Priorities include innovative approaches, expansion of successful local efforts, and benefits for communities with the greatest needs. The objective builds on public stormwater investments in Philadelphia and Camden, seeking to maximize their environmental, social, and economic benefits.
