None of this seems likely. It's like moving out of San Francisco because an earth quake might happen. Even if a freak hurricane arrives (it shouldn't since the waters aren't tropical, but whatever lets say this somehow changed in the next 50 years), even if, you'd have weeks to evacuate people, so casualties shouldn't be too high. Infrastructure would be damaged yes, but doesn't seem to me like something that devastates the country. The water will eventually be pumped out. And btw what do the once in 10000 years storm defense are preparing for if not just that?
