Why not just leave San Francisco basically as it is? The city works okay right now. You can get around it reasonably well. Housing and transport are only a problem if you're going to keep trying to cram more people in there. That's silly. Part of what makes San Francisco one of the USA's most appealing cities is that it hasn't expanded all that much in the last eighty years or so -- due to its unique geography which prevents outward expansion. (The population in 1930 was 634,000, in 2010 it was 805,000.)
