Time running out for latest Hatteras Inlet dredging project

Members of the Dare County Waterways Commission made imminent plans at their meeting on Monday to speed up dredging in Hatteras Inlet in order to accomplish as much as possible before the March 31 deadline.

Dredging the South Ferry Channel, also known as the Connecting Channel, in Hatteras Inlet is allowed from October 1 through March 31.

But after that, approval is required from the N.C. Department of Environmental Quality, the Division of Coastal Management and the U.S. Army Corps of Engineers to receive permission to dredge outside the permitted season.

As of Monday, the dredging contractor’s plans were to tackle Big Foot Slough in Ocracoke until the first week of March, and then move over to Rocky Rollinson Channel, followed by the mouth of the harbor.

The hierarchy of the plans frustrated several commission members, who were concerned about accomplishing all the hotspots before the end of March.

“If something isn’t done by the end of the timeframe, it would be the entrance of the channel?” confirmed commission member Ernie Foster. “In terms of absolutely critical, having a way in an out of the harbor is key.”

In addition to the tight timeline which could potentially be tightened even further by unforeseen weather events, another wrench was in the works as the sidecaster dredge Merritt remains unavailable for the months of February and March due to scheduled repairs.

“This is a crisis situation,” said Foster. “If we have a major weather event, there will be no dredging in Hatteras this year.”

Joen Petersen, chief of plants for the Corps, outlined several potential plans for working without the Merritt, and addressing the bar in Hatteras Inlet – a roughly four foot deep shoal – which has become a problem area for even small draft vessels.

“There are two ways (to proceed), if we can get across with the Currituck,” said Petersen, referring to the hopper dredge that could be enlisted for the project. “We can work from the outside in…or we can try to change Currituck into a sidecaster dredge, and dump sand as we’re going through.”

Converting the Currituck into a sidecaster dredge would be an easy process, although the vessel would not propel dredge material as far as the Merritt.

“It’s feasibly possible,” said Petersen, noting that he would have to garner permission, but that it could likely be obtained. “If they can do it in Regulatory, they will go out of their way to make it happen.”

When asked about the amount and number of days dredging should occur, Petersen recommended that the commission start with a heavy-duty and robust wave of dredging to clear the bar, and then address maintenance dredging later.

An opportunity to speed up the process was also examined, as dredging that was scheduled for another North Carolina inlet near Holden Beach could potentially be postponed, moving Hatteras Inlet up in line.

“Lockwood Folly (Inlet) is scheduled for three weeks of dredging, but there is no (date) restrictions there,” said Petersen.

“Jim Medlock will do calculations, and estimate the cubic yards of sand that needs to be moved,” Peterson said. “Based on these numbers, and how rigid their schedule is, he will look at the choices.”

Medlock is the Wilmington District Navigation Program Project Manager for the Army Corps of Engineers.

Utilizing that information, and the potential for moving up the schedule, the commission and the Corps developed an imminent plan to get the ball rolling by the end of the week, before the dredging at Lockwood Folly Inlet begins.

There are still funds remaining for the project, which would cover the bulk of the dredging, and Waterways Commission and Dare County commissioner Danny Couch said he would approach the rest of the board and request the funds.

“The Board of Commissioners care about the inlet, and this is not an unreasonable request,” he said. “We have some money there, so let’s make the push.”

Couch said he would reach out to the board and add the proposal if necessary to the BOC’s agenda for their meeting on Monday, February 19.

“We need to move fast,” said commission chairman Dave May. “This is crunch time.”

In other news, the members examined the progress of the commission’s long-term goal to find more room to place dredge material.

After the Corps completes its maintenance dredging of Rollinson Channel that is scheduled to begin on Feb. 21, the disposal capacity on Cora June Island, a bird island located near the Hatteras docks, will be at maximum level.

Meanwhile, the N.C. Wildlife Resources Commission is working to approve reconstruction of the so-called DOT Island, a dredge island near the Hatteras dock that used to be five times its current size.

If permitted, new dredge material could be placed up to 25 acres. The agency is also evaluating whether additional material can be deposited on Cora June.

The permit for utilizing DOT Island is being finalized, and once that is complete, the proposal goes to 13 separate entities which have a collective 30 day comment period to respond to the endeavor.

After that, it goes to the Division of Coastal Management which has an additional 150 days to make a determination.

Couch and fellow commission members, along with Sarah Schweitzer of the N.C. Wildlife Resources Commission, were also examining a newly available potential grant for dredge spoil islands, or the “beneficial use of dredge material.”

“The US Army Corps of Engineers is looking to recommend 10 projects for the BUDM program that would allow for transport and placement of dredged material at full federal expense,” stated the original announcement of the grant from the American Shore and Beach Preservation Association.

“This was one of ASBPA’s top priorities over the past 2 years, because it would push the USACE to work more closely with states and stakeholders to make better use of dredged material from federal navigation projects, and could potentially help some local communities access beach quality sand that might otherwise be wasted,” according to the ASBPA statement.

Also, as a ‘Pilot Program’ this will result in a report that recommends how (the Corps) can better and more efficiently utilize dredged material going forward.”

“We’re on the right track,” said Couch. “We just have to push, and keep pushing. We have some momentum here and we have to keep going. We have no other options.”

The next Dare County Waterways Commission meeting will be on March 12 in Manteo, which will also be the last meeting for Project Manager Administrator Jenny Jones, who after 24 years of service with the county, including 17 with the Waterways Commission, is retiring in March.

    Why are there date restrictions on when it can be dredged? Who cares?

    And why would they not want a new dredge spoil island created? I seem to recall concerns that if an island were too large, predators could then live there, so why not another small island? Seems like that would make the bird lovers happy?
