Looks like CS2 will have mixed use zoning! - Beehaw

The one that’s part blue, didn’t notice it at first but I think it’s mixed use.

Finally contemporary urbanism.
Contemporary? That's how it's always been. Zoning is new, and Euclidian Zoning is extremely recent and only really prominent in NA. In the past people would be able to have literally any use in any bulding.
True I was mostly commenting about how citybuilders are often stuck with strictly differentiated zoning of the of the Modern and Industrial periods, not the entire history of urbanism.
