The Three Bays

APCC’s Restoration Coordination Center and our partners have been awarded $1,067,574 by the U.S. Environmental Protection Agency Southeast New England Program and $423,300 from the Massachusetts Office of Coastal Zone Management for stormwater management to improve water quality in the Three Bays. This five-year project is being completed as a collaborative effort by APCC, the town of Barnstable Department of Public Works, Horsley Witten Group, and the Barnstable Clean Water Coalition (formerly Three Bays Preservation). 

The Restoration Coordination Center is managing the project, organizing and conducting outreach activities, coordinating the project team, and tracking project progress and success. The project team is also providing a total of $300,000 in in-kind contributions bringing the total project value to greater than $1.7 million. Download our Intro Outreach PowerPoint presentation or watch it as a video (MP4).

The Three Bays watershed is severely degraded by nitrogen and bacteria resulting in poor water quality, impaired habitat, and closures of beaches and shellfish areas. Stormwater runoff and fertilizer use contribute over 23% of the nitrogen entering the bays resulting in algal blooms, fish kills, and bacteria contamination that regularly impacts fishermen and beachgoers. Through this project, locations for stormwater improvements will be identified and prioritized for the town and at least two of the top priority sites will be addressed through installation of “green” technology to treat and remove pollution from runoff before the water reaches the bays.

Throughout the project there will be multiple opportunities for the public to get involved to learn more about the impacts of stormwater on water quality in the bays, help with demonstration projects, monitoring and maintenance, and provide input into the project.
