Boston tells Army Corps it needs both a citywide flood plan and Moakley Park project
In a public comment letter released Tuesday, the city backed the Army Corps of Engineers' finding that Boston faces at least $54 billion in flood damages by 2090 without action, and pressed for changes to proposed barrier alignments in four neighborhoods.
The city of Boston has asked the U.S. Army Corps of Engineers to advance a comprehensive coastal flood plan alongside an early-action project at Moakley Park, according to a public comment letter the city posted Tuesday.
The letter responds to the Corps' draft feasibility report and environmental assessment for Boston Harbor. The city said it agreed with the Corps' findings on coastal flood risk, including an estimate of at least 42 inches of sea level rise and at least $54 billion in damages by 2090 if nothing is built. With an estimated return of $4 for every $1 spent, the city said the case for federal investment is strong and that the Corps' no-action option is not acceptable.
City officials wrote that Moakley Park cannot wait for federal funding but protects only one neighborhood from one flood pathway, and asked the Corps to commit to a timeline for moving the remaining projects in its comprehensive plan past 10% design toward federal approval. The city put the non-federal share of the full plan at at least $3.5 billion, which it called its largest investment ever, and said the Boston Green Ribbon Commission is preparing a financing blueprint.
The letter said Boston has built $48 million in coastal resilience projects over the past 10 years, has $32 million under construction and $59 million planned over the next five years.
The city also objected to several proposed alignments, saying options in East Boston and downtown would block evacuation routes on Route 1A and Commercial Street, and that a Charlestown option would leave out hundreds of properties. About $13 billion in damages would remain across Charlestown, East Boston, Dorchester and South Boston even with the recommended projects built, the city said.
The Corps' comment period is open through Sept. 18.
