mod - companion to "Cargo Ships", "Alien Biomes" and "The Shallows"

[Keysivi]

I have an idea for a small mod related to landfill placement:

If there are ships and shallow water - why not prohibit landfill placement on water and deep water?

This will add a bit of realism to the game and give additional motivation to use ships instead of landfill. Plus, it will not allow you to accidentally place a landfill in deep water.

I would do it myself, but I don't know how.
