Our story started in 2015 with an informal gathering of municipal leaders in Philadelphia to discuss the challenges of implementing green stormwater infrastructure. Today, we are highly connected peer learning network of 60 organizations across North America.


The Exchange is building a practical playbook for implementing green stormwater infrastructure that any city can adopt. We seek to use this playbook to accelerate implementation of green stormwater infrastructure affordably and equitably throughout North America.


Our members are cities, counties, and utilities who have committed to green stormwater infrastructure as a strategy for community resilience and to sharing their knowledge with their peers. Please find our current member list here.


We work primarily through learning groups focused on priority issues identified by members. Learning groups are forums where peers share information, experiment, and create solutions faster, together.
