In response to intensifying hurricanes that have hit the New York and New Jersey coastal region in recent years, the U.S. Army Corps is proposing a handful of measures to reduce the risk of storm damage. The proposals include constructing barriers, either in-water or land-based, and floodwalls that would stretch over 2,000 square miles across New York Habor to protect the area’s waterfront neighborhoods.
The barriers, already being used in cities like Stamford, Conn. and London, would have gates that remain open to let ships pass, but close when a hurricane is advancing (h/t WNYC). After completing a study that looked at nine high-risk areas, including 25 counties in NY and NJ, on the Atlantic Coast, the Corps this month will present the proposals at public information sessions across the two states.

The subway’s crippling, century-old infrastructure is not the only reason behind the system’s constant delays and disruptions. The other problem involves about 13 million gallons of water, or more depending on the rainfall, that gets pumped out from underground on a nearly daily basis. A perpetual hazard, water can drip onto electrified equipment, cause a short and create chaos, as the New York Times reported. After ineffectively using only sandbags and plywood to fight flooding in the past, the Metropolitan Transportation Authority has turned to more high-tech solutions, like flood-proof doors and inflatable gaskets, which will be a part of its $800 million emergency action plan to fix the subway.

With the October 29th anniversary of superstorm Sandy approaching and storms leaving the world’s coastlines waterlogged, 6sqft recently covered a new report predicting rising sea levels and a growing flood risk. Now a new study, published Monday, found that New York is almost halfway through a 500-year span of rising seas that began in 1800–and the worst is yet to come. But according to the Washington Post, this increased likelihood of flooding has a silver lining.
