SANDY HOOK -- More than three years after Hurricane Sandy severely damaged concession buildings at Sandy Hook, federal officials say they plan to demolish three of the six structures.

Instead of having freestanding concession stands at those beaches, those sites will now have food trucks and vending machines, according to park superintendent Jennifer T. Nersesian.

After working feverishly following Hurricane Sandy to reopen Sandy Hook, park officials had to find alternatives for the services provided at the concession stands. On Monday, they announced their decision about the fate of most of those buildings.

Nersesian said the beach center stands at areas B, C and E will be demolished and utility hookups will be installed at areas C and E for the mobile food trucks and vending machines.

Repairs will be made to the buildings at beaches G and I and those, too, will be equipped with utility hookups for mobile food trucks and vending machines.

Nersesian said park officials have not yet determined what to do with the busiest beach center, at Area D, which housed the Sea Gull's Nest, a popular restaurant. That building sustained extensive damage during Hurricane Sandy and like the other concession stands, has been closed since the Oct. 29, 2012, storm because of the lack of federal funding to make the necessary repairs. The National Park Service has contracted with mobile food vendors since then to service park patrons.

"We want to restore services that our visitors expect wherever possible," Nersesian said. "We also must use a thoughtful approach to rebuilding in the most resilient way for these areas."

She said mobile trucks will continue to provide food services for this season and park service officials should have a plan for the building housing the Sea Gull's Nest by the fall.
