Massachusetts faces significant flood risk from coastal storm surge, riverine flooding in the Connecticut, Merrimack, and Charles river basins, and urban flash flooding in the Boston metro. Boston sits on filled tidal flats and has experienced recurring coastal flooding. The January 2018 nor'easter caused severe tidal flooding along the waterfront and the March 2010 Patriots' Day flood caused hundreds of millions in damage. The Connecticut River valley through western Massachusetts including Springfield, Northampton, and Greenfield faces regular riverine flooding, with the 1936 and 1955 floods among the most devastating in New England history. The Merrimack River floods through Lowell, Lawrence, and Haverhill. Worcester faces flash flood risk from the Blackstone and Quaboag rivers. The state has over 350 NFIP-participating communities. Sea level rise projections of 2-4 feet by 2060 threaten significant portions of the Boston waterfront, Logan Airport, and coastal communities. Boston has developed a Climate Ready Boston initiative addressing flood resilience including plans for harbor barriers and green infrastructure.
