Alliance for the Chesapeake Bay

About us

For the last 50 years, the Alliance has worked to bring together communities, companies, and conservationists to improve the lands and waters of the Chesapeake Bay. We seek to work upstream, to prevent pollution from where it starts.

We believe in collaboration, inclusivity, and action-oriented progress based on science. Our vision is for clean streams and rivers flowing through resilient landscapes, cared for by the 18+ million people who live, work, and play in the Chesapeake Bay watershed.
