Fact Sheet-New York Harbor, NY-Maintenance and Stewardship

Published Feb. 1, 2018

DESCRIPTION:  Manage and monitor ocean placement of dredged material at Atlantic Ocean’s Historic Area Remediation Site (HARS) and man-made reef sites that accept dredged material from navigation projects within the New York Harbor; as well as, oversee all sampling, testing, and evaluation of testing data for all proposed ocean disposal projects.  Operate and Maintain the Caven Point Marine Terminal and the 31 miles of navigation channels and anchorage areas within the Upper and Lower New York and New Jersey Harbor to include preliminary engineering and design, with ocean placement testing scheduled for future maintenance dredging of various channels that comprise the Harbor.  


AUTHORIZATION:  The New York Harbor Federal Navigation project consists of the 53 ft. Ambrose Channel, southerly entrance, Bayside (a.k.a. 35 ft. Sandy Hook Channel) and 35 ft. Main Ship Channels (a.k.a. Chappell Hill) adopted in 1884, modified 1933, 1937, 1958, 1965, 1982, Water Resources Development Acts of 1986 and 1990. Also, the Anchorage Channel adopted in 1930 and modified in 1937, and Water Resources Development Acts of 1986 and 1990; the removal of Craven Shoal to a depth of 30 feet, and a channel between Staten Island and Hoffman and Swinburne Islands to a depth of 16 feet.   Anchorage Areas and Channel along New Jersey Pierhead Line adopted in 1935. Additionally, Anchorage Areas (Gravesend Bay and Red Hook Flats) adopted in 1965 and modified in 1982.


COMMERCE:  New York Harbor contains five interconnected but separate channels and two adjacent anchorages all of which are used by international vessels, harbor pilots and the U.S. Coast Guard and supports 140 million tons of commerce per year.  Channels and anchorages are maintained alternating years.


STATUS:  Plans for the continued management and monitoring of ocean dump sites (i.e. HARS) for dredged material have been agreed to between the New York District and EPA Region 2.  These plans require extensive chemical, biological and physical surveys of select areas within the site.  Monitoring will assess the physical integrity of capping contaminated dredged material placed during historic disposal activities, assuring that required cap thicknesses are maintained and that any erosion has not caused unacceptable adverse impacts.  The HARS has received on average 4 million to 6 million cubic yards of dredged material per year from Federal and private dredging projects within the New York and New Jersey Harbor.  Complete E&D and award a maintenance dredging contract for the Sandy Hook Channel with actual work performed during the fall of 2018.  The last maintenance dredged occurred in FY 2017 with placement of the sand at the Sea Bright Borrow Area, allowing this sand to be re-used beneficially for future beach renourishment projects along the NJ shoreline.
