You can’t just add in “moar housing” in a vacuum and declare mission accomplished. Let’s say SF doubled its housing. Where are all these new residents going to park? So, now it’s housing and parking that needs to be fixed. Assume none of these new residents have cars? Ok now it’s housing and public transit that needs to be fixed. Where are their kids going to go to school? So we need more school capacity, too. How mu…
Chicken-egg problem though. If you say transit doesn't go places or doesn't run often people claim the density is too low and we need more people to use it. Can't have the same excuses just used to block everything. Just start building everything, high density housing, dedicated bus lanes, multi-level parking garages, better utilities.
I'd advise against this. We did that in Madison, and before we even got very far doing this, Mother Nature started to hint to us that it might not be a good idea.
Maybe there are places where you can just build Willy-Nilly. (I doubt it, but what do I know?) I suspect, however, most places are like Madison, just not quite as delicate. You probably have to be REALLY careful about what you're building.
And even more careful about where you're building it.
