The Barrier Project extends from the West Branch
eastward across the East Branch of Stamford Harbor, in the City of Stamford, Fairfield County, CT
It protects approximately 460 acres consisting of principal manufacturing plants of the city, residential
sections, and a portion of the main commercial district.
The Reservoir Regulation Team (RRT), in Concord, Massachusetts directs the water
regulation activities for the New England hurricane barriers such as Stamford. By way of radio and satellite communications,
RRT constantly monitors river levels and weather conditions that influence flood control decisions.
The barrier design was established through cooperation with the U.S. Weather Bureau and the Beach Erosion Board
affiliated with the Texas Research Foundation of Texas A&M University. The basis for the design storm was the
transformation of the September 1944 hurricane. This storm, when it was off the Cape Hatteras, N.C. coast, had
the greatest energy of any known hurricane along the Atlantic coast. The 1944 storm was transposed so that it
would be entirely over water between Cape Hatteras and the New England coast, resulting in a central pressure
of 27.8 in. mercury near the mouth of Narragansett Bay, Buzzards Bay, and Long Island Sound. The transposed
storm was moved northerly with a forward speed of about 40 knots along a track passing over New England 49
nautical miles west of Montauk Point, Long Island, creating sustained winds of 90 mph at the mouth of Long
Island Sound and 55 mph from the southwest quadrant at the Stamford location in western Long Island Sound.
Within Long Island Sound, at Stamford, a tide surge associated with this storm was computed to be 10.4 ft.
This surge was added to the mean spring high water elevation of 4.4 Ft-NGVD, resulting in a 14.8 Ft-NGVD
stillwater elevation. It was further determined that wave heights associated with this storm would be on
the order of about 2.0 ft at time of peak surge resulting in a top of barrier elevation of 17.0 Ft-NGVD.
A 14.8 Ft-NGVD design stillwater elevation is slightly greater than a 500-year tide level.
