Sea walls for a cleaner look at the shoreline

Sea walls for a cleaner look at the shoreline

Yes, and a new product made from concrete shaped like those Jacks looking 4 pointed tetrapods that could be dumped for fill.

You wouldn't happen to know how these are built IRL would you? I would suspect that either large piles are driven into the ground and then backfilled, but I'm not certain. I ask because I was trying to think through how they would be implemented in game.

This would be an awesome addition! Maybe this could be a feature of T2 retaining walls? Combine that with some of the other suggestions for better placing and back filling mechanics and I think this could improve the game a lot!
