About GSI Partners

Building a just green and thriving economy by advancing the local GSI industry and innovation.

An example of SBN’s mission in practice, SBN’s GSI Partners are building a thriving, equitable, and climate resilient economy by advancing the local GSI industry and innovation. We are a network of local businesses in the green stormwater infrastructure industry, including firms in GSI design, construction, maintenance, and material supply. Formed in 2012 and initially catalyzed by Philadelphia’s ambitious and innovative stormwater management plan, Green City, Clean Waters, SBN’s GSI Partners advocate for a green first approach to public and private stormwater management, and for those public and private investments to remain with local firms. Through its GSI Partners initiative, SBN is working to maximize the local economic, environmental, and social impact of nature-based solutions to stormwater management.


“We have been a member for 7 years. SBN is reaching out to us on so many levels–for policy input, business opportunities, funding suggestions–and every event feels unique and important.”
