J & J, you are both missing my point.

It's not about rescue plans or evacuation schemes which you should bother about now.
It's about dikes, dunes etc. It's about creating overflow areas where the water can be stored, installing pumping engines, etc. It's about the future!!!
Or will you rather wait for the next time?

And because of the scale of all these measures that has to be issued by a governmental authority which has to issue a special tax for that.
