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?
