Entire island states like Tuvalu face a similar fate and they have nowhere else to go... I know it's unrelated to this particular situation but the sea is the sea and doesn't care much about a costly sandy bump. Yes, the Netherlands managed to pull some tricks but the site is different and they used hard structures anyway.
Honestly at this point Tuvalu should use the money it makes from the .tv domain (and otherwise) to relocate and buy some vast farmland abroad. It's sad to see the state of affairs some islands are in. That's one kind of refugee immigration I could back. Just 11,000 people.
