The town risks saltwater intrusion in its wells, and also faces a longer-term threat to the vital roads onto the island.

The city’s terminals are crucial to Maine’s energy needs, but the storage tanks, roads and rail lines are all at risk as the ocean rises.

Two feet of sea level rise coupled with a storm like the infamous Blizzard of 1978 would be enough to submerge most homes in Camp Ellis.
