Being Dutch; we had a major flooding in 1953. Decide we didn't want or accept that. Build up the water defenses. There was a flood danger in 1995, but nothing failed. Upgrade the system, to make it even better.

Did decide to buy an apartment on the 3rd and 4th flood, instead of on the ground level. Just in case. Failure rating of the sea defense around me was 1 in 100.000 years. (they change the rating system to something else now)
