Southern Maine lost more than a quarter of its coastal sand dunes in the historic 2024 winter storms that caused an estimated $70 million in damage from record-setting high water levels, according to a new study from the University of New England. Less than half of the dunes at four beaches in Biddeford, Kennebunkport and Saco had come back at the end of last year’s seasonal growth cycle, when dunes are at their highest, according to research published Monday in Geomorphica, an earth sciences-based science journal.
