Our story started in 2015 with an informal convening of municipal leaders in Philadelphia to discuss the challenges of implementing green stormwater infrastructure (GSI) where participants noted the unique value of connecting, sharing resources, and learning from and with peers.

Today, we have over 60 member organizations, including utilities, municipalities, cities and counties who are implementing infrastructure at scale and individual members are typically managers of each organization’s GSI program. Click here to view our full member list.


The GI Exchange is member-led: our activities and focus areas are defined according to member interests, needs, and priorities. We focus on quality connections to create the conditions for collaboration, trust, and engaged leadership among our members. We believe that collective learning and peer-to-peer exchange lead to innovation in the field.
