I don't disagree, but where I live zoning is a large part of the problem
The zoning in my area perpetuates unwalkable, uncyclable, parking lot infested sprawl, because single family houses take up 84% of the available land.
I don't want industry to move into neighborhoodseither , but I wouldn't mind commercial or retail, currently prohibited.
That would ne ideal, but sadly city planning in the United states is too political.
We'll never get anything done relying on city planning, so the only thing that seems possible is to improve the city organically, through markets.
