On the North Carolina Outer Banks, two homes in the small village of Rodanthe now stand on the edge of the ocean, their fate uncertain. Since 2020, 11 nearby houses have already crumbled into the Atlantic, swallowed by relentless waves and shifting sands. The problem isn’t just the big storms like Hurricane Erin, which recently passed miles offshore—it’s the steady invasion of the sea driven by beach erosion and climate change.
Rodanthe, with its population of about 200 people, juts further into the Atlantic than any other part of North Carolina. This location makes it especially vulnerable. High tides have recently been pushing water up into the foundations of these two surviving homes, leaving onlookers like local resident Jan Richards to watch and wonder how much longer they will last. She pointed out where two houses once stood, now gone, reminders of how quickly the ocean can claim land here.
The National Park Service reports that over the past five years, 11 homes in Rodanthe have been lost to the surf. This isn’t unusual for barrier islands like the Outer Banks. These islands form from sand and sediment carried by ocean waves and are always moving and changing. Sometimes they even vanish entirely. Building on these shifting sands has always carried risks.
Years ago, homes here were simpler and easier to move as erosion crept closer. Today’s larger, more permanent structures face greater danger. Even the Cape Hatteras Lighthouse, an iconic landmark built in 1870, had to be moved more than half a mile inland 26 years ago to avoid the encroaching ocean. Back then, the lighthouse sat 1,500 feet from the water. Now, the sea is just 300 feet away, and the shoreline still retreats by up to 15 feet a year in some spots.
The houses’ foundations rest on wooden pilings driven deep into the sand. As strong as they might seem, pounding surf washes away the sand around these pilings little by little, weakening their hold. David Hallac, superintendent of the Cape Hatteras National Seashore, compares it to a toothpick stuck in wet sand—without enough depth, it won’t stand against the wind.
When a home collapses, the debris can drift 15 miles along the coast, posing hazards to people and the environment. There is also a risk of pollution from broken septic systems. A report from state and local officials says nearly 750 of North Carolina’s 8,800 oceanfront structures are at risk from this ongoing erosion.
To fight back, some communities bring in dredged sand to rebuild beaches, but this costly process is a challenge for small places like Rodanthe. Other ideas involve buying out homeowners, relocating, or tearing down threatened buildings—all expensive and difficult to fund.
Coastal erosion isn’t just a local issue. Braxton Davis, director of the North Carolina Coastal Federation, points out that similar problems are happening along the California coast, near the Great Lakes, and along many U.S. rivers. Rising sea levels mean this problem will only grow.
For now, the two houses in Rodanthe remain, standing on fragile grounds where homes once crumbled and disappeared. Time will tell how long they can hold on to the shifting edge of the Atlantic.
