I wonder how coastal they intend to be. They make a lot of claims about repairing the wetlands and coastal regions, but a lot of it is likely going to be underwater in the next 25 years because of rising sea levels [0], regardless of how many wetlands are repaired. And I suspect infrastructure like this probably has to be usable for something like 100 years to payoff. Maybe they're actually going to build inland, where the eventual coast will be?

This was my question as well. If they’re as close to the shore as the picture makes it seem, they’ll be underwater with the first Cat 1 they come across, and huge cat 5s are becoming more and more common as time goes on. I wouldn’t want to invest here because how will you keep those 200 foot tall structures standing in 150 mph wind??

There are levees and other tech that has existed for centuries and millenia to stave off flooding.

I don't think so. Likely the pad with last 10 years max.

In any case, I highly doubt that but in any case sea level is almost certainly going to rise below a meter. Filling a meter higher with sand is a pocket change for this project.
