The US Army Corps of Engineers, EPA, NYS Department of Environmental Conservation, and local partners have reached a significant milestone by beginning the construction of a multi-year coastal wetland habitat restoration project in the Buffalo Outer Harbor Slip #3. The project uses clean sediment dredged from the navigation channel to create wetland habitat that will benefit native plants, fish, and birds and the local community.
