About this file
Summary
This is a construction document set for dredging work at Hammocks Beach State Park, prepared by the North Carolina Department of Natural and Cultural Resources, Division of Parks and Recreation. The project involves dredging approximately 42,000 cubic yards of material from the Cow Channel at Bear Island in Swansboro, NC (SCO Number 06-06920-03A), with the dredged material to be deposited on the Bear Island beachfront for beach renourishment. The dredging work extends approximately 5,750 linear feet from Station 24+50 to Station 82+00, with material placement spanning approximately 2,700 linear feet along the Bear Island Service Road. The channel is to be dredged to a depth of 8 feet below mean lower low water with an allowable over-depth of one foot. The construction documents, dated April 20, 2026, include comprehensive plan views, cross-sections at multiple stations, and typical details for channel markers and tide gauges. All elevations are referenced to mean lower low water and are based on bathymetric survey data from October 22, 2024.
The project requires the contractor to establish all necessary lines and grades, perform pre- and post-dredging bathymetric surveys for acceptance and payment, and manage dredge material placement with special attention to the beach access stairs and ramps. The dredging permit is being obtained by the owner (Department of Natural and Cultural Resources), while the contractor is responsible for all other permit requirements, navigational notices, and necessary approvals. The construction documents include detailed specifications for channel markers with reflective sign boards, tide gauges installed at each side of the channel, and provisions for a temporary berm and tapered transition zone to integrate the beach fill with existing conditions. Beneficial material placement is prioritized at the beach access location until design elevations are achieved, after which remaining material is distributed along the adjacent shoreline as directed. The project is presented as a rebid opportunity.
