14-mile dike could protect Greater Boston from sea level rise

Barrier would run from Cohasset to Swampscott

We propose building a 14-mile dike barrier between the shoulder highlands of Cohasset and Swampscott. The dike would be located some eight miles out from Deer Island, complete with residential and commercial developments, windmills, solar collector farms, and recreational areas. A simple dike barrier with a 200-foot-wide top and reaching 120 feet from seafloor to storm-surge top would require some 246 million cubic yards of material. Bi-directional locks could provide access for all crafts, protecting Boston’s commercial activity and its waterfront. integrity.  https://commonwealthmagazine.org/environment/14-mile-dike-protect-greater-boston-sea-level-rise/
