My place will be flooded somewhere between a 4m and 5m rise. I live right on the other side of a levee next to a large river, so this is not unexpected. The river has never flooded here as far as I'm aware, but who knows what could happen. Luckily, I am moving in a few months and my new home will be safe until about 10m. So not much better I guess, but this is what happens when you live in a valley connected to a large delta system.
