A few weeks ago, Staten Islanders in the area set more than 65,000 beach grass plants along the berms, which were designed to fortify the barrier in response to Superstorm Sandy.
"It is crucial that people stay off the dunes at all times, especially while they're young and growing in," wrote Parks Department spokeswoman Tara Kiernan. "Dune grass can be killed by people and pets…and ATV's…trampling them."
The berms were originally installed in 2013 as a part of a $2.8 million project, paid for largely by the U.S. Army Corps of Engineers and the Federal Emergency Management Agency.
"The city did not spend millions of taxpayer dollars to build these dunes just for the enjoyment of some thrill-seekers," Ignizio said in a statement.
"They should take a look around Crescent Beach to witness the damage that still exists from Hurricane Sandy," he added, "and maybe then they’ll understand why these dunes are critical to protecting these flood-plagued communities from another storm surge."
