SHIP BOTTOM, N.J. (CBSNewYork/AP) — A long-awaited beach replenishment project is underway at one of New Jersey’s top vacation spots.
The U.S. Army Corps of Engineers has started work in Ship Bottom on a $128 million project that will restore nearly 13 miles of beaches and dunes on Long Beach Island.
Sea Bright Councilman John Lamia said the beach was replenished by the U.S. Army in 2013, just after Sandy. At the time, about 300-ft of sand separated the sea wall from the surf. Now, it’s more like 50.
“Beach erosion is a natural process, but not at this pace. What typically takes 10 years to degrade has taken less than just two,” Lamia said.
Lamia showed CBS2’s cameras that dunes planted in March have already been wiped out. He wants and needs to know what is happening.
“Right now, it’s important. We’re coming up on beach season, trying to attract more people to Sea Bright,” he said.
The beach drives the local economy.
“Our businesses depend on those visitors,” he said.
Jon Miller, a coastal engineer with Stevens Institute said there are a couple of possibilities.
“Sometimes when we do the replenishment there’s a pocket of very fine material that washes away quickly,” Miller said.
Underwater terrain may also be to blame.
“”Depending on how it looks waves will focus on certain areas,” Miller said.
It might just be that one section of the beach gets crashed upon more frequently.
The Army Corps of Engineers said in cases like this, construction of erosion control structures like offshore breakwaters or artificial reefs is not cost effective.
Renourishment has shown to be the most cost effective method for mitigating erosion.
Right now, there is no way to know for sure. Research is necessary to decide if anything can or should be done.
