With even a moderate-term fix likely to cost $3 million or more, New Jersey officials are considering what to do to save the lighthouse. Nancy Patterson, president of the Maurice River Historical Society, says something needs to be done now.

State and local governments routinely shore up the perimeter of the lighthouse property with 3,000-pound (1360-kilogram) sand bags and hastily bulldozed earthen walls. During normal conditions, the bay is about 40 yards (37 meters) from the lighthouse; satellite photos from 1940 show at least four times as much beach between the lighthouse and the bay as there is now.
