Hurricane Erin's massive waves threaten to isolate North Carolina's Outer Banks
Share this @internewscast.com

There’s a well-known T-shirt on Hatteras Island in the North Carolina Outer Banks that reads: “One road on. One road off (sometimes)” — humorously highlighting the ongoing struggle between Mother Nature and a slim stretch of pavement linking the narrow barrier island to the wider world.

Mother Nature is likely to prevail this week. Hurricane Erin is expected to remain hundreds of miles offshore but is still sending 20-foot (6-meter) waves or larger crashing over the vulnerable sand dunes on the islands.

Officials have ordered evacuations for Hatteras and Ocracoke islands even without a hurricane warning, as the slender highway known as N.C. 12 is expected to be damaged and washed away in several areas, potentially isolating villages for days or weeks.

The 3,500 or so Outer Bankers who live there have handled isolation before. But most of the tens of thousands of vacationers have not.

“We haven’t experienced waves of this magnitude in quite some time, and the vulnerable areas have only deteriorated over the past five years,” noted Reide Corbett, executive director of the Coastal Studies Institute, a collaboration of several universities researching the Outer Banks.

The Outer Banks are defined by water

In a basic sense, they are sand dunes that were tall enough to stay above the ocean level when many of the Earth’s glaciers melted 20,000 years ago.

In certain locations, the barrier islands extend as far as 30 miles (48 kilometers) from mainland North Carolina. To the east lies the vast Atlantic Ocean, while to the west is the Pamlico Sound.

“Water, water everywhere. That really resonates on the Outer Banks,” Corbett said.

The most developed and populated section of the Outer Banks is in the north around Nags Head and Kill Devil Hills, which aren’t under the evacuation order. South of the Oregon Inlet, carved out by an 1846 hurricane, is Hatteras Island, where N.C. 12 serves as the sole link to the mainland. Further south is Ocracoke Island, reachable only by boat or plane.

The first highways to reach the area were built more than 60 years ago. And the Outer Banks started booming, as it went from quaint fishing villages to what it is now, dotted with 6,000-square-foot (550-square-meter) vacation homes on stilts.

Maintaining the highway is arduous

On a nice day, what look like snowplows and street sweeper brushes wait on the side of N.C. 12 to scoop and sweep away the constantly blowing sand.

When the storms come, water from the ocean or the sound punch through the sand dunes and wash tons of sand and debris on the road. In more extreme cases, storms can break up the pavement or even create new inlets that require temporary bridges.

The N.C. Department of Transportation spent more than $1 million a year on regular maintenance to keep N.C. 12 open during the 2010s. It also spent about $50 million over the decade on repairs after storms.

But the state estimates Dare County, which includes most of the Outer Banks, brings in $2 billion in tourism revenue a year. So the cycle of clean up and repair continues.

The repairs take time. Hurricane Isabel in 2003 and Hurricane Irene in 2011 both cut inlets into Hatteras Island and ferries were needed for two months. It can still take days to reopen N.C. 12 after more routine Nor’easters.

The erosion is constant

It’s not just storms that impact the island. As the planet warms and polar ice melts, rising ocean levels threaten the Outer Banks. In a place where most of the land is only a few feet above sea level, every inch of sand counts.

In the town of Rodanthe, which sticks the farthest out into the Atlantic, the churning ocean has swallowed up more than a dozen homes since 2020. Officials think at least two unoccupied houses are likely to be lost if the waves from Erin are as strong as predicted.

The Outer Banks are still home

Shelli Miller Gates waited tables on the Outer Banks to earn money as a college student in the late 1970s. She remembers houses with no air conditioning, televisions or phones. And she adored it.

“I love the water. I love the wildness of it. It’s the way I want to live my life,” the respiratory therapist said.

It’s a lifestyle embraced by many. The area’s shorthand “OBX” shows up in many places as a source of pride, including the first three letters on license plates issued by the state.

The isolation contributes to a sense of community. Gates has seen people band together countless times when their connection to the outside world is severed. And there is always the allure of getting to live someplace where others just get to visit.

“There’s things everywhere. There’s earthquakes and blizzards and floods. Look at the poor people out in western North Carolina,” Gates said. “There are so many things that can happen to you. I feel like you have to find the place that feels like home.”
