Why Green Stormwater Infrastructure

Solving urban and environmental challenges by building with nature.

Green stormwater infrastructure (GSI) uses vegetation, soils, and natural systems to manage rainwater where it falls—integrating green solutions into streetscapes, parks, and developments.

Examples include rain gardens, tree trenches, planters, and green roofs.

Together, these systems:

  • Reduce flooding and combined sewer overflows
  • Improve air quality and neighborhood cooling
  • Strengthen community health
  • Create and sustain local jobs
  • Retain investment within the regional economy

Philadelphia’s Green City, Clean Waters plan—launched in 2011—has generated an estimated $4 billion in total economic impact and supports over 1,000 jobs per year, while strengthening neighborhood resilience and environmental equity.
