Capturing the Multiple Benefits of
Green Infrastructure
The GSI Impact Hub is an interactive platform with a suite of resources and tools to help quantify and communicate the multiple benefits – or co-benefits – of green stormwater infrastructure (GSI) and assist in siting and planning projects to achieve the greatest impact.
GSI is an innovative approach to managing stormwater runoff in ways that mimic the natural environment by using plants, soil, and stone to filter and manage stormwater where it falls rather than diverting it directly into sewer systems. GSI includes practices like rain gardens, green roofs, bioswales, street trees, and rain barrels.
Many cities throughout the United States and Canada are adopting GSI methods to reduce polluted stormwater runoff and meet water quality-related regulatory requirements. Unlike conventional gray infrastructure approaches to stormwater management (think gutters, sewers, and pipes), GSI provides many additional economic, social, and environmental benefits that advance a community’s livability and resilience to climate change.
The GSI Impact Hub is more than just a website; it is a comprehensive resource center with a collection of resources and tools that capture these co-benefits so that practitioners, advocates, policymakers, and leaders have the evidence-based information they need to design and implement GSI projects that provide the greatest benefits to their communities.
