Montauk beach erosion surfaces sooner as sandbags relent to rising sea levels

A hamlet study backs a recommendation to enact a "strategic retreat" of downtown businesses inland to combat the threat, but East Hampton Town is mulling a $15M-$17M beach restoration project.

Buried sandbags meant to defend Montauk’s downtown from the Atlantic Ocean have been clearly visible on the beach since late summer, an earlier start to seasonal erosion that underscores the need for a more permanent solution to stabilize the shoreline.
