Southern New England’s coastline — the region’s economic engine — is under siege, and this relentless enemy is gaining force. It can’t be subdued by 20-foot-high seawalls or controlled by old-school hay bales. It’’s allies include parking lots, beachfront development and climate change.

Coastal communities here are increasingly experiencing the impacts of an encroaching ocean. Storm waves are eroding beaches and flooding developed areas. Rising sea levels are taking land. The ocean’s power even when it’s seemingly tranquil is unmatched, but when it’s angry our continued disrespect proves costly.
