The contractor will be required to close one man-made cut in the salt marsh north of the Satilla River in Camden County, GA: Noyes Cut (approximate location: 31.0101° N, 81.5466° W). This work is part of the Noyes Cut Ecosystem Restoration Project and has the objective of increasing tidal exchange throughout the system, restoring salinity gradients to Dover Creek, and reducing shoaling in Umbrella Creek.

The site is remote and only accessible by water. It is located approximately 10 linear miles south of Brunswick, GA and is 11 linear miles from the Woodbine boat ramp located at 103 E 1st St, Woodbine, GA, 31569 and 8 linear miles from the Tidelands Nature Center boat ramp located at 100 S Riverview Dr, Jekyll Island, GA 31527. The site is subject to large tidal variations typical to the GA coast and the site may not be accessible at all tide stages for all types of equipment. The contractor will verify site accessibility for selected equipment. Vessel traffic in the vicinity of the site is expected to be minimal and limited to occasional recreational boaters and small commercial crab fishing boats.

The cut closure structure will consist of a trapezoidal rubble mound-type structure with a 3:1H:V slope and an approximately length of 495 ft at Noyes Cut. The width at the crest will be approximately 6 ft for each structure. The structure will be made entirely of GDOT Type I riprap. The current estimate for rock quantities is approximately 21,000 tons for Noyes Cut. The contractor will be responsible for furnishing, stockpiling, and placement of all rock.

The rock will be carefully placed within the template using approved equipment in a manner to produce a wellgraded mass of rock and to minimize impacts to fish and wildlife. The contractor will install aids to navigation consisting of signs and other markings mounted on pile foundations at each cut closure location.
