Why not have both? Did the original barrier plan have transportation or ship dock component? If you move the big shipping out of Chelsea Creek, the area gets a lot nicer for affordable housing and makes a cleaner waterway and greener marshes. One of the many bonuses besides saving $200 billion in flood damage replacement costs. Imagine king tides twice a day without it. If you love Boston you should be advocating for this. If you live on the harbor, in the Neponset, Fore, Charles, Mystic, Weir, or Weymouth Back River watersheds, same deal. Name te price and I'd call it a bargainI'd prefer a freight and passenger rail line instead of the Atlantic Wall Road. The rail line could have a spur line to the Logan air terminals for freight and passenger access, and tie into rail systems to the south and north. Your proposal looks similar to the 1918 report at https://www.greenribboncommission.o...easibility-of-Harbor-wide-Barriers-Report.pdf.
