Contractor Great Lakes Dredge and Dock Co.’s hydraulic dredge Texas began replenishment work Jan. 18 in Beach Haven, transporting sand removed from Little Egg Inlet onto ocean beaches on Long Beach Island’s south end.

Great Lakes was awarded a $18.4 million contact to clear dangerous shoals from the inlet, a major thoroughfare for boat traffic between southern LBI and Brigantine, and to use the sand to repair beaches and dunes in Beach Haven and the Holgate section of Long Beach Township.

As the state Department of Environmental Protection explained, the removal of sand from the inlet will clear a navigable boat channel 1 mile long and 24 feet below mean sea level “to accommodate the numerous commercial and recreational fishing vessels, private boats and other craft that use the inlet to access Barnegat Bay, Great Bay and the Intracoastal Waterway.”

“The project calls for dredging and placement of 700,000 cubic yards of sand, with an option for an additional 300,000 cubic yards if necessary,” said DEP press officer Lawrence Hajna.

Great Lakes anticipates that all work and demobilization will be completed by mid-March, dependent on weather, Hajna added.

The project, funded by the DEP’s Shore Protection program, “is designed to have the multiple benefits of restoring beaches that are economically vital for shore tourism and storm protection while making it safe for boaters to again use Little Egg Inlet,” said David Rosenblatt, DEP assistant commissioner for engineering and construction. “We look forward to having the project completed in time for the next tourism and boating season.”

As Hajna noted, operations were near Jeffries Avenue in Beach Haven near the end of last week, and “Great Lakes has indicated that work in Beach Haven will take about two more weeks, depending on weather.”

Following the completion of work in Beach Haven, the dredge will begin operations in Holgate, near Rosemma Avenue, and will work southward to the border of the Edwin B. Forsythe National Wildlife Refuge. Pumping in this section should take about two weeks.

As Great Lakes explains on its website, hydraulic – or cutter suction – dredges are “floating platforms equipped with a rotating cutter that excavates the sea floor by feeding the loosened material into a pipe and pump system that typically transports the material and water slurry up to five miles away from the site.”

Once the contract work and demobilization is complete, Beach Haven and Long Beach Township will reinstall dune fencing, crossovers and dune grass.
