Large portions of the structure in the Upper New York Harbor at the Verrazano Narrows will sweep open, allowing ship traffic to enter the harbor and navigate existing channels under normal conditions. During storm conditions or as sea levels rise in coming years, gates can be closed and raised as much as 35 feet out of the water. The barrier will stave off a storm surge that would wash up the Hudson River. In a major storm event such as a category three hurricane, or higher, thousands of people would lose their lives. After the waters recede, the region would be racked by human health hazards, transit disruptions, and ruined subterranean infrastructure. Eventually, as sea level rise becomes permanent, the gates may need to be deployed full-time. The plan calls for a second set of gates to be constructed nearby to serve as a gigantic navigational lock.
In addition to the moveable barriers, a ten foot impermeable seawall will be constructed around Lower Manhattan from the Battery as high as Canal Street to accommodate for overall rising sea levels and normal weather events that are certain to wreak havoc on city infrastructure with increasing regularity as sea levels continue to rise past safe levels. Officials agree the measure is the only way to secure the region from what New York City climatologists call
