Opposite (lack of water rather than an excess) reason than GP, but still a climate change (drought is a result of climate change) induced problem. Building foundations in Back Bay will crumble if there is an extended period of drought there.

Didn't get time to finish replying/sourcing articles, but most climate projections show that the Boston area will see much more nuisance flooding and much more severe Nor'easters, specifically in low lying areas. This is a big reason for Boston's Climate Action Plan being created - as South Boston, the Harbor, and Backbay are all very flooding susceptible. There are some good articles about it in the Globe and on Boston Govt's website, but it's too much of a pain to source through that.
