MANTOLOKING — Mantoloking Mayor Lance White is warning residents of the presence of sinkholes along the beach and has asked that residents remain vigilant and safe.

“There is a condition in Mantoloking running from Lyman street heading north to Bay Head that poses a hazard to the pedestrians on the beach,” Mayor White said in an email.

“There have been incidents of sinkholes appearing in this area.”

Mr. White said the Army Corps of Engineers, New Jersey Department of Environmental Protection [NJDEP], are working with the borough to solve the issue.

According to Stephen Rochette, public information officer for the Army Corps of Engineers Philadelphia District and Marine Design Center in Philadelphia, this is not necessarily a new issue for Mantoloking.

“I checked in with our team and they informed me that the issue existed before our dune and beach fill project,” he said. “It has to do with the way the [stone revetment] wall was constructed and covered with sand. Voids have historically been present along the new sections of the stone revetment in the north end of Mantoloking.”

The wall involved is the rock revetment along the dunes.

“Settling along the rock revetment has caused sinkholes to occur at or below the surface of the dune, creating a safety hazard,” Mayor White said.
