Beachfont homes will wash away this century, but not (likely) within 30 years from now.

But you never know. There's a northwestern storm over the North Sea right now. Parts of Hamburg and other coastal towns in northwest Germany have flooded.

The Oosterscheldekering in Zeeland and other storm surge barriers are all closed. The expected rise is well within limits, so no worries.

The Roman roads around Utrecht (some good distance away from the sea) are buried over a meter deep in the ground, buried under sand, soil and clay sediments from seasonal river flooding. There must be many but they only find them when something gets built. They were on dry land when they were built back then, but are below sea level by now, just like much of the land anyway which would flood if it wasn't for the dikes.

The sea has been rising about an inch a century. It now rises at an inch per decade, and increasing.
The Netherlands won't flood before I die. But my great-grandchildren will have to move unless if we can get the CO2 back down again in time.
