New Islanders.

A fictitious history of Boston’s (un)managed retreat.


Managed retreat is a frightening prospect for many. Because radical shifts in climate policy are unlikely, though, retreat of some kind may become necessary. This is the story of how Boston began an unmanaged retreat into the unlikely safety of its islands, and the planning responses it engendered.


2025

Category 3 hurricane comes to Boston, hitting the Dorchester Bay particularly hard.


First known use of Spectacle Island for a post-storm, informal settlement for the displaced.


2040 Rising sea levels + increasingly powerful, frequent hurricanes transform Dorchester Bay coastline from a knowable boundary to an interstitial zone of property damage and disinvestment. Semi-permanent camps form on the islands.


Sea Level Rise + Hurrican Force Surges by 2100.

Unflooded land


Residents flee flooded homes to the uninhabited and by now largely ignored Harbor Islands, particularly Spectacle and Long.


2045 Responding to pressure from the media and Department of Justice, Boston’s mayor issues two executive orders, separately creating the Boston Harbor Island Temporary Community and Settlement Task Force (“Task Force”) and the Boston Floodplain Reinvestment Commission. The two bodies make similar recommendations. Following those proceedings, the City Council creates the Boston Harbor Islander Authority, an quasi-public agency.

2048 In concert with the BRA, the Islander Authority authors and implements “Island Living 2100,” a master plan that “formalizes” Islander communities through mass evictions of informal settlements, land assembly/disposition, and development. A “Settlement House” is created on Long Island, a nod to the evicted communities and charity history on the island. Island Living 2100 closes the most flood-prone parts of the former Boston mainland and directs investment toward high density housing on the Islands.
