Dredgineer here - The Palms were a big project as far as dredging goes, but all the engineers knew it was a crazy idea. Almost every reclaimed land project has severe liquefaction issues. The Osaka airport in Japan has had major issues since they built the place. IIRC - it sunk a couple inches after the tsunami hit it. \n\nHowever - ain't nothing cooler than seeing a hopper dredge in action. They probably sucked up all kinds of cool shit out there.
