BROOKLYN - A local group is demanding that the city build sand dunes along the Coney Island and Brighton Beach shorefront to provide a protective barrier from the ocean.

The Natural Resources Protective Agency says that if sand dunes were in place before Superstorm Sandy, there might not have been as much damage.

"They are cost effective. They are quick to put up. They have been proven to reduce storm damage," says Ida Sanoff, executive director of the agency.

A spokesperson for the mayor's office says that specific areas need different solutions. They say that since Sandy, the city and the U.S. Army Corps have placed 600,000 cubic yards of sand on the beaches in Coney Island and Brighton beach to protect them from future storms.
