Well here (NZ), reclaimed land is often a very problematic climate and tectonic risk. Lots of discussion about managed retreat. Ok, plenty of 19th C stuff was done badly, but engineering for sealevel rise, earthquake (liquifaction), tsunami and storm exposure isnt cheap. Also, we have had too much finding-out-the-hard-way that coastal wetland was performing valuable environmental services that are not easily replaced. I am happy to have strong regulations around that. To make it work and be economic to maintain over very long term, then I think you need to have large area of land created compared to length of your seawall (the Dutch situation) and yes, the easy ones have been taken.
