The thing about San Francisco is that while greenfields have been exhausted in the city, the San Francisco Bay Area is largely undeveloped. We are always arguing over San Francisco, or Palo Alto (ick). Outside of the 47 square miles of San Francisco proper are almost 3200 square miles in San Mateo, Santa Clara, Alameda, and Contra Costa counties.

There's No Substitute For A Substitute

Interesting argument for Singapore-style dense, livable greenfield development. Probably another good idea that will be strangled in its crib by California's tax structure.
