We are a network of over 6,000 stormwater professionals comprised of professionals within the Chesapeake Bay Watershed and beyond! Through our network, we work to align and integrate the efforts of thousands of individuals working on the stormwater problem across the Bay. CSN works to advance the science of watershed restoration, build capacity through training and events, foster the next generation of stormwater professionals, and share successes and innovations. We host events and trainings including our yearly CUSP (Chesapeake Urban Stormwater Professionals) program, the BUBBAs (Best Urban BMP in the Bay Awards), and our Chesapeake Stormwater Retreat.
