A sinkhole swallowed Nicolas Cage’s driveway. Yours might be next.

There is a kind of terror-tinged embarrassment that comes from dozing off on your beach towel on the sand, only to find a rising tide intrude upon your mid-nap bliss, lapping at your toes and sweeping away your sunglasses.

It is a truth I relearn every June, one that arrives like the season’s first sunburn: The ocean is inevitable, and Poseidon always reclaims his own. Actor Nicolas Cage learned a far more serious — or more expensive, certainly — version of that lesson earlier this month, when a furious high surf siphoned the ground beneath his Malibu, California, mansion, collapsing his driveway and front porch into a gigantic 30-foot-by-30-foot sinkhole. The cave-in ruptured a gas main, swallowed an access road, and forced dozens of locals to evacuate. In the process, it put into stark, cinematic relief the un

It’s impossible not to imagine Cage standing on the edge of that yawning pit as he might in one of his films, bombastic in his bafflement, every outsize gesture a pantomime of confusion. But no one should have been surprised. As far back as 1976, the California Coastal Commission denied a proposal to build a home on the lot where Cage’s Malibu home now teeters over the void, citing “concerns over wave hazards.” In 1986, the same commission rejected another residential proposal on the land, deeming it an “extremely hazardous area” threatened by waves and erosion.

So why, just a few years later, was a home built there anyway, one that would eventually come to be owned by a certain Hollywood eccentric? A few years after their initial rejections, the waterfront lot’s original owners were able to convince the commission that with enough clever engineering, including a sea wall and concrete stilts, the home, its septic system, driveway, and access road could be protected from the sea god’s wrath. But much like Odysseus before him, Cage has found the hard way that the lord of waves does not easily forget his due. “What is the Grail but Earth itself?” he once

In this case, at least, Cage chose the wrong cup. But Cage is hardly alone in laying out his home atop the wrong stretch of sand. Nearly all of the nation’s coastal communities — from ritzy enclaves like Malibu to working-class quarters of the Rockaways in New York — rely on coastal engineering to remain inhabitable, dumping sand or erecting sea walls to put off a perpetually and increasingly rising tide.

To put this into perspective, almost one-third of Americans live along a coastline, and while few of us have the kind of luxury oceanfront views that Cage and his neighbors enjoy, our beachside apartment complexes, utility lines, and coastal highways suffer from the same risks his driveway does. Most of us, however, lack the benefit of a second home or a private island to flee to if something goes catastrophically wrong.

When a sinkhole opens underneath a celebrity’s driveway, or a stilted home collapses into the sea, it is a reminder that we have built huge swaths of our beloved coastal communities on land that was never meant to sit still. If we want them to survive, we will need to learn to embrace new ways of packing our beach towns up and wheeling them further upshore. Logistically implausible as it may sound — difficult as, say, stealing the Declaration of Independence — it’s a process that several American communities have become much better at in recent years.

“This is not a problem that is unique to Malibu, which just so happens to be some of the most spectacularly beautiful and spectacularly expensive real estate in America,” said Kara Murphy Schlichting, an environmental historian at Queens College in NYC. “This is a question that is coming for all of America’s coastal communities.”

The void that swallowed Cage’s driveway with the gusto of the actor chewing scenery in one of his films was no ordinary sinkhole. In fact, if you asked a geologist, they would tell you that it was not, technically speaking, a true sinkhole at all.
