Every time I hear how important zoning is I point to Houston. Ending zoning makes no difference when developers insist on design inertia because of the opportunity cost and risk of trying something new. And there are concrete obstacles thornier than zoning, like a "democratic" process that facilitates a NIMBY chorus favoring separate uses as much as any 1950s planner.
Well, although I see what you are saying, consider this: isn't
true design inertia
actually the traditional urban concepts embraced by new urbanism? new urbanism is, after all, in fact not much more than
old urbanism. and, furthermore, assuming that the design inertia you highlight (I get what what you were pointing out)
is in fact something counterproductive to policy or regulatory based attempts to better the built environment, you still wrote
when developers insist on design inertia. my question is, what about when they DON'T? While your point makes perfect sense in some contexts, I don't think the premise that developers
necessarily insist of an inertia of design such as that you allude to holds up, at least not
all the time. In fact THAT, I think, was the point of one of the videos above. i.e., if and WHEN developers DO attempt to ride renewed interests in mixed use development over otherwise or seemingly otherwise prohibitive opportunity cost waves, it would be tremendously useful if zoning were not in the way. True, as you pointed out, there are other issues to be contended with. BUT, if zoning is removed as an obstacle to mixed use construction and development, I think it is fair to say that perhaps the BIGGEST obstacle will have been overcome. Houston may be (and hopefully is) an anomaly. One of the biggest shortcomings of modern zoning is not that it REQUIRES single use districts, but that it PERMITS them. So, I'm not necessarily saying abolish zoning altogether. I am merely stating that changing zoning laws to accommodate more mixed use if and when there is a demand for it seems to be smart. moreover, the really interesting point is that the legal basis for zoning which separates uses (health and safety) can actually be used to combat the very thing it currently serves as a foundation for, in that mixed use developments are increasingly being thought of as healthier (because they are more walkable).
