States L2 Landing Page Tabs

Located in the Northeastern United States, New York is the seventh-most densely populated state in the U.S. The state covers 54,555 square miles and ranks as the 27th largest state by size. The Great Appalachian Valley dominates eastern New York and contains the Lake Champlain Valley as its northern half and the Hudson Valley as its southern half. Much of New York State borders water.

A study finds that although the “wilderness breach” created by Hurricane Sandy in 2012 has reached a relatively stable size and location, the channel and shoals will keep changing in response to weather. Related research shows the breach isn’t likely to increase storm-tide flooding in Great South Bay.

When Hurricane Sandy struck the south shore of Long Island, New York, on October 29, 2012, it caused substantial erosion of the beach and dunes. Storm waves cut through Fire Island National Seashore’s wilderness area, forming a breach. The resulting channel allowed water to flow between the Atlantic Ocean and Great South Bay.
