(Could not get pics from e360 so this pic is from CBS: https://www.cbsnews.com/news/buxton-north-carolina-outer-banks-homes-collapse-humberto-imelda/)
The destroyed homes, part of Cape Hatteras National Seashore, left the beach awash in debris, according to the National Park Service, which manages the coastline. Their loss comes just two weeks after another home collapsed into the sea in Buxton.
This hurricane season is EXTREMELY unusual because of how quiet it has been for the US. No storms in the Gulf and those in the Atlantic have dissipated or curved back out to sea.
Yet we still have homes falling into the Atlantic Ocean. We still have sunny day flooding in most major cities along the eastern seaboard.
People are being lulled into a false sense of security about hurricanes. I read that 1,000 people move to Florida every day.
Next year will not be like this one.

The homeowners should be cited for littering.

(24,291 posts)When those homes were built, there were a couple of hundred yards of beach between the houses and the ocean. Water erosion has swept away those beaches and the houses are getting destroyed. If you build on a barrier island, sooner or later the ocean will claim it.
My wife built a 2-bedroom 2-bathroom beach box 8-feet up on stilts on Ocracoke Island, south of Hatteras where the houses fell into the sea. After Hurricane Dorian swept across Ocracoke with a 7-foot wall of water, when many low-lying houses were destroyed, she sold her house. Sooner or later, that island will be hit harder.
Barrier islands in hurricane zones dont make much sense.

No homes or businesses should be built on barrier islands AT ALL.
And they most definitely should not be REBUILT after hurricane damage.

Storms and even high tides, as weve been seeing in recent years, cause flooding and overwash of sand onto oceanfront roads, said Laura Moore, a University of North Carolina at Chapel Hill professor and one of the studys lead authors. Thats problematic for transportation, but the washing up of sand is actually vital to maintaining island elevation and width.
For decades, the state has tried to protect Highway 12 the only road connecting Ocracoke Island to Hatteras and the mainland by building dunes, placing sandbags, and repairing washed-out stretches after every major storm. But Moore and her colleagues warn that these strategies may be making the problem worse. When we protect roadways by building dunes and placing sandbags, were preventing sand from washing onto the islands like it naturally would, Moore said. That means the islands become lower and narrower over time. And when sea levels are rising as quickly as they are now, that narrowing and lowering happen even faster, which means roads and property become more and more vulnerable.
The paradox, researchers say, is that the very storms that threaten homes and infrastructure are also essential to the islands survival. The storm events we need to protect roads and buildings from are actually the same events that would otherwise be building island elevation and allowing islands to grow wider, Moore said. The more successful we are in preventing storm impacts, the more quickly were essentially managing the barrier islands out from underneath us.
The team used advanced computer models to simulate different management scenarios: continuing current practices, adding beach nourishment, or allowing natural overwash to resume while exploring alternative transportation options such as elevated bridges or rerouted ferries. The results were sobering. In scenarios where Highway 12 continues to be defended in its current location, the models suggest the road will require increasingly frequent repairs while the island itself loses elevation and width. If we invest in the roadway, it will be a short-term investment, not a long-term one," Moore said. The report comes as Erin offers a stark illustration of those findings. The Category 1 hurricane isnt even expected to make landfall, yet its offshore winds and storm surge are already swamping the highway and flooding low-lying streets. It doesnt take a storm making landfall for these roads to be affected, Dr. Moore said. Peoples lives and livelihoods are hugely impacted when that road closes, sometimes for weeks at a time. But if we continue managing barrier islands the way we are, the ability to live on them at all may eventually be at stake.

(1,840 posts)Billions and billions of dollars spent from Houston to New Orleans to Miami to Hatteras onward just to pretend we're holding back the ocean. The Army Corps of Engineers won't be around much longer under Chump and with all the other brutal cuts to Fed departments, nature will indeed take its natural course in these areas.
Nature bats last.
