MANTOLOKING, N.J. — Alex Staal never saw this town at its worst, submerged and ravaged by Hurricane Sandy, 90 percent of its homes damaged by the storm. He started visiting only two years ago, and what he knows is a vast sandy expanse for relaxing and refreshing dips in the Atlantic Ocean.

And the need to move his car every two hours.

“It gets so annoying,” Mr. Staal, 44, of Philadelphia, said, referring to the town’s two-hour parking limit. He recalled scampering across the scalding-hot midsummer sand to move his car and momentary mental lapses that have earned him more than a half dozen tickets.

But as the federal Army Corps of Engineers replenishes this town’s beach and builds new dunes, one of the obligations of benefiting from taxpayer-funded beach reconstruction is ensuring that the beaches can be used by, well, taxpayers. So the town is proposing doubling the parking limit to four hours and expanding the number of parking spots.
