imo, there should be maybe 3 zones and that's it: mixed use up to six stories (basically allows everything but regulates noise levels, chemical, etc outputs so you don't have pig farm/iron smelter levels of pollution/stink here. Obnoxious things light night clubs are allowed if they can limit their annoyance levels. Everything within the highly permissible zoning should be approved very fast, think a week at most, ideally a couple days). mixed use over six stories. This would allow everything in the previous zone but allow higher builds without rezoning and be fairly fast for approval. Then industrial zoning where you can build the stuff that can't keep itself within the pollution/noise/etc regulations of the first two (think pig farm, garbage dump, industrial factories).
