Looks like that city is a bit scrunched for land, Junglecutter.
Interesting SC4 taxes. There's no option to differentiate taxes between clean and dirty industries in SC3 - you just have to hope you get clean. Which isn't that easy to get. I did notice a huge pollution decrease when I bulldozed my entire original, entirely-dirty-industry Industrial zone and it rebuild in the 1970s, though.
My city of Bristol is now in the year 1989. It's by far the largest city I've ever had.

As can be seen, it's a lot larger than in 1934.

A few areas fell outside even this farthest-out zoom.
