That is how I will go to work, in case they have to use the last back-up plan. Estimations are it will be less than once in 200 years that that will have to be used though.
If you live for 80 years, that's an uncomfortably high lifetime probability.
At that point, it's time to move to Switzerland:
Why would I, chance that where I live will get flooded is once in about 4000 years. The area 2 km away from me is a last resource overflow basin, if all other options fail. The farms are on terps, most of the main road is above water level, and people will know way in advance that the area may get flooded. So, time enough to bring cattle and people in safety, with enough food to last long enough.
Chance that you get flooded in a Swiss valley, after massive rainfall will be substantial too, when the climate change keeps going on this way.
