How erosion is affecting your favorite Shore town’s beaches

Rowdy teenagers after dark and rising rental prices may jeopardize the Jersey Shore’s image, but there’s a more dangerous threat looming that could leave lasting impacts on Shore towns for decades to come.

Erosion — the natural process of wind and waves whipping against the shoreline, sweeping away the sand with each pummel — is an ongoing challenge for local officials as climate change causes sea levels to rise and more severe storms accelerate the process.

Without protection, beaches erode and flood damage can ravage a Shore town, which has started to play out in towns like North Wildwood, where recently stormwater flooded past dunes and crept closer to residential property.

It doesn’t help that the wheels of bureaucracy turn slowly to jump into action, said North Wildwood Mayor Patrick Rosenello, whose town hasn’t received a beach “renourishment” — where sand is dredged up and moved to the shore to staunch erosion — since after Hurricane Sandy a decade ago.

“The Jersey Shore as we know it wouldn’t exist without renourishment projects,” said Rosenello, whose town has been embroiled in a legal battle with the state over such projects since last year. “If in Philadelphia, protective barriers and bulkheads along the Delaware collapsed and the city decided not to rebuild them, Front Street pretty soon is going to be underwater.”

In New Jersey, there are federal and state Shore protection programs to ensure the 130 miles of shoreline gets renourished. But landing a big federal-state project for a given Shore town requires a lot of red tape, including funding, approvals, and — the most expensive part of the project — the mobilization of bulldozers, dredging equipment, and barges, according to Stewart Farrell, founder and former director of the Coastal Research Center at Stockton University.

Farrell and other researchers say it’s easier to get support from federal and state governments when there are dramatic events like hurricanes, but the chronic and ongoing erosion that happens each year doesn’t draw the same kind of attention. “A nor’easter storm can do as much damage as a hurricane,” Farrell said.

Jon K. Miller, the coastal processes specialist for the New Jersey Sea Grant Consortium, copublished research on “nuisance erosion” last fall. It’s a form of erosion that is analogous to “death by a thousand paper cuts,” he said.

“This past winter is a good example where we didn’t necessarily have a Hurricane Sandy, but there’s a number of locations along the East Coast, North Wildwood, and Atlantic City that had some pretty dramatic impacts more from the buildup of erosion over the past several winters than one singular severe storm.”

As the perpetual dance of filling in beaches only to have them eroded away will continue for as long humans develop along the shoreline, researchers say New Jersey will need to properly fund and coordinate its renourishment projects.

What does this mean for the average beachgoer? No big changes for most this summer.

“Anybody going to places like Cape May, Wildwood, Sea Isle City, Avalon, Stone Harbor, Margate, and Longport — no worries, no big deal. They won’t even notice anything different from last year,” Farrell said. “But North Wildwood is going to look a little strange because the water is all the way up against the bulkhead and dunes.”
