I've been thinking a lot about TOD lately (especially in the SF Bay Area), and I keep coveting the huge parking lots that are by so many BART stations, thinking how much nicer they would be as TODs - but of course that would put a lot more pressure on the parking. Ideally, IMO, there would be little or no parking in a TOD - but that doesn't really seem feasible yet, given how many people still rely on cars. So then I'm thinking - what if you build a parking structure, but build it with its future conversion to housing (or another use) in mind. Is this being done anywhere, or does anyone have an idea if it would be possible? I would love to see a zoning code that required new parking structures to be built like this!
