Construction began Monday on Longport's 11th Avenue revetment, a rock sea wall that was compromised during Hurricane Sandy last year.

The $500,000 project is part of a larger push by the borough to repair and improve its shorefront protections, including eventual ocean dunes and new bulkheads throughout the municipality.

Borough Engineer Dick Carter said the revetment, also referred to as a jetty, facing the Great Egg Harbor Inlet failed during Sandy, allowing water and rocks to infiltrate the nearby 11th Avenue. The Bridgeton-based South State, Inc. began construction this week with subcontractor 4H Construction, based in Cape May Court House.

It is expected to be completed in 30 to 45 days and should be an improvement over what was there before Sandy, he said.

The project is being financed through the borough's $4.5 million emergency bond, said Mayor Nick Russo. Reimburse-ments for the project through the Federal Emer-gency Management Agency will be applied to repaying that bond.

"Once we get those rocks in, we'll be able to repair the street," Russo said. "It's a step in protecting Longport's infrastructure."

A ribbon-cutting ceremony for the revetment is scheduled for 10 a.m. Thursday.

Carter said other planned improvements include upgrades to various bulkheads, slated to begin this fall, and beach replenishment and dune construction through the U.S. Army Corps of Engineers. The latter project is still in the planning phase, he said.
