In 2009, the Dutch television network RTL reported on a proposal to build a Dutch-style floodwall across the Narrows at the mouth of New York harbor (SLYT), complete with an animation of what it was designed to protect against: flooding of 4 meters into Manhattan & the surrounding areas. This uncannily resembles what transpired this Monday.
