Tracking Coastal Change
While storm events and breaches are part of a barrier island's natural processes and breaches can provide ecological benefits, decisions about breach management must be balanced by concerns that the breach may exacerbate flooding in adjacent communities of Long Island's south shore.
As of March 2018, the wilderness breach on the northern shoreline was 590 feet, and the width of the southern shoreline of the breach was 1,180 feet. Extensive shoaling has occurred within the breach, as well as in the Great South Bay just north of the breach, and in the Atlantic Ocean south of the breach.
