Boston faces significant risks from coastal flooding, with potential damages exceeding $54 billion by 2090 if no action is taken. Key neighborhoods, including Charlestown, East Boston, Dorchester, and South Boston, remain vulnerable to 'residual risk' even with proposed projects. The city emphasizes the need for comprehensive flood protection to safeguard its neighborhoods, infrastructure, and economy. Without federal investment, critical areas like Moakley Park and the Raymond L. Flynn Marine Park could remain exposed to severe flooding events.
