The city of Boston and the U.S. Army Corps of Engineers released a draft plan designed to protect the city's most flood-prone areas and prepare to manage the risks of sea level rise. 

According to an article by Jordan Wolman in CommonWealth Beacon, "The draft plan is set to act as a roadmap for how New England’s largest city, one-sixth of which is built on filled tidelands, can navigate the more than four feet of sea level rise the Army Corps projects will hit Boston by 2090 as the world continues to warm."

The plan would cost an estimated $10 billion and would build new floodwalls, levees and floodgates in vulnerable areas. The city could fund up to 65% of the Army Corps' recommendations with federal funds. 

Without action, the city could face losses of roughly $54 billion by the end of the century. "Key regional assets like Logan Airport, hospitals, I-93, I-90, and rail stations remain highly vulnerable. Neighborhoods more than a mile from the ocean could experience severe flooding in the next 25 years."
