CBEP delivers findings on sea level rise impact for coastal communities of Casco Bay

The Muskie School's Casco Bay Estuary Partnership (CBEP) has issued a series of reports on the effects of sea level for 10 municipalities on Casco Bay’s shoreline.

Supported by funding from the Maine Coastal Program and the U.S. Environmental Protection Agency, CBEP examined these municipalities in order to identify potential areas of marsh migration and possible impacts to existing developed areas due to tidal inundation from sea level rise. Each community received a report designed to help its municipal staff and decision-makers understand risk levels and potential impacts associated with sea level rise, and to provide science-based projections to inform future policymaking responses.

The series, titled “Sea Level Rise and Casco Bay’s Wetlands: A Look at Potential Impacts,” includes editions for Brunswick, Cape Elizabeth, Falmouth, Freeport, Harpswell, Phippsburg, Portland, South Portland, West Bath, and Yarmouth.

The reports are available at
