Video: Dewatering New York City
Video by Mary Cochran
Assigned by the Federal Emergency Management Agency (FEMA), the U.S. Army Corps of Engineers provided technical assistance and dewatering to 14 locations in the New York City metro area. Available in high definition. Through a partnership of private industry professionals and city and federal agencies, flood waters from nine FEMA mission-assigned transit locations in New York City were removed less than two weeks after Hurricane Sandy's record-level storm surge inundated the area. Dewatering operations at five other FEMA mission-assigned locations in the New York City metro area have also been completed. Storm surge from Hurricane Sandy flooded New York City's network of underground tunnels with nearly 300 million gallons of seawater. Five subway tubes, two AMTRAK tunnels and three of the city's primary roadways, including the longest coastal tunnel in North America was flooded by storm. Joint Task Force Unwatering, assisted by the United States Navy's Supervisor of Salvage and Diving (SUPSALV), and the U.S. Coast Guard Strike Force teamed with the New York District, AMTRAK, the Metropolitan Transit Authority, and other city, local, state, and federal organizations to unwater the major tunnels under New York City in less than two weeks. The dewatering task force, led by USACE, concluded its transit dewatering mission in New York City on Nov. 10 with approximately 275 million gallons of saltwater removed from tunnels, underpasses, and other areas in the New York City metro area.
