Robbins Rest on Fire Island will need emergency dune repairs because powerful storms earlier this week caused significant erosion in that area, a federal official said Thursday.

“This was a major nor’easter — there were some pretty high waves,” said Chris Soller, superintendent of the Fire Island National Seashore.

“There was an overwash, and the road flooded,” although no houses appeared damaged, he said.

The National Park Service is working with the U.S. Army Corps of Engineers, and state and local officials to build a protective dune in Robbins Rest as quickly as possible, Soller said.

An Army Corps spokesman was not immediately available for comment.

The emergency project would follow the outlines already devised for Robbins Rest as part of the Army Corps plan to build about a dozen miles of dunes and berms on the 32-mile-long barrier island. Together, the federally funded berms and dunes will stand about 15 feet high.

The project has kicked off at the island’s eastern and western ends.

Soller said the bidding process is being finalized for the stretch of communities that includes Robbins Rest and runs from Seaview to Fair Harbor.

Dunes in front of Ocean Bay Park and Davis Park, where Suffolk County first must acquire or move homes, might not get built until late this year or 2017.
