Rain-heavy storm drops a bomb on earthworks being recreated at North Carolina's Fort Fisher. It will take several more weeks for crews to fix erosion, finish project

Historic rainfall along a stretch of North Carolina’s coast heavily eroded replica earthworks going up at Fort Fisher, creating a cascade of mud and delaying the opening of a new visitor center by at least a month.

Communities south of Wilmington – among them Kure Beach and Carolina Beach – received more than 18 inches of rain in 12 hours on Sept. 16. The National Weather Service said such inundation occurs once every 200 years.

Fort Fisher State Historic Site now says the park reopening, originally set for this Friday, will be pushed back until the earthworks are completed. Officials are not sure when that will occur.

“There has been a fair amount of damage around the site due to flooding/storm damage. Some trees and limbs came down, along with some pieces of the (replica) palisade fence,” said assistant site manager Chad Jefferds.

The visitor center roof had a small leak and the road to a park maintenance facility was washed out. “The sand in the washout was essentially quicksand.”

By far the biggest damage was to the unusual earthworks project.

The site closed in April to make way for completion of the visitor center and the recreation of three traverses, bombproofs, a magazine and the sally port. Fort Fisher’s use during World War II helped the Allied cause but destroyed some of its familiar defensive traverses. They were removed to make way for an airstrip when the area was used for training anti-aircraft and coastal artillery units.

Jefferds said beyond scraping away much of the muck at the earthworks site, the contractor must wait for the proper moisture levels for replacing dirt. “It’s not a simple process.”

“The Underwater Archaeology Branch facility sustained some damage from water intrusion. There are many homes on the island that took major flood damage and some condos have been condemned,” said Jefferds.

A photograph the site posted to social media on Friday was taken last Monday from the front of the visitor center facing north toward the parking lot. “Our thoughts are with all those affected by the storm,” the park wrote.

Fort Fisher was built on the peninsula between the Cape Fear River and the Atlantic Ocean, south of Wilmington. It is best known as a crucial coastal bastion for the Confederacy.

On Jan. 15, 1865, after a naval bombardment, the Federal army attacked from the western, river side while Marines pushed in from the northeast bastion. The fall of the “Gibraltar of the South” cut off blockade runners and the last supply line through Wilmington to Robert E. Lee’s Army of Northern Virginia.
