Amsterdam is like that because they built it on a literal tidal floodplain reclaimed using dikes and when they put in a foundation under buildings they used wooden posts which eventually rotted away causing buildings to slump into the soft, wet earth underneath.
The problems and geology of the eastern US with respect to sinking land are much different.
Sweet post. To me this looks like the makings of a sustainable community and I remain pretty optimistic. Curious what the numbers for Kbin would look like.
