All tiles are full tiles where specific coastal tiles shall be collected within +/- 2 hours of Mean Lower Low Water
Dredging is performed to the minus 38 feet Mean Lower Low Water
Cape Wind Associates plans to install and maintain a pile-supported scientific measuring tower extending approximately 197 feet in the air above the mean lower low water
elevation in the ocean waters of Horseshoe Shoals in Nantucket Sound as well as an associated measurement device imbedded in the sea floor.
Negotiations are nearly completed with a private firm, NPI LLC, which will provide $3 million toward the construction of the dock, which will be extended out to -60 feet at mean lower low water
(or at the average low tide) and will be 1,200 feet long.
The authorized federal project includes a navigation channel 6ft deep below mean lower low water
(MLLW) and 100ft wide extending approximately 6,000ft from the confluence of the East and Neck Rivers out into Guilford Harbour.
The proposed new harbor basin will be dredged to minus 20 feet Mean Lower Low Water
(MLLW) to accommodate large commercial vessels so they will not touch bottom on the lowest tides of the year (minus 5.
