I never actually followed through on my Bay Area applications but when I was applying, I found people had great things to say about the faculty and part time MBA at Cal State East Bay. Give them a look and see if they have what you need. Also there were a couple of commuter schools in SF that seemed pretty standard continuing/executive ed offerings. Also, I don't know what UC Davis' GMAT range is off the top of my head but you might find that their low end is where you need it. To be honest, though, you might have a chance at Haas, if you had some kind of compelling history or noble life mission.
Good luck! Maybe one of the left coasters will be able to add more but definitely check out CSEB, UC-D.
EDIT: You're good at UC-D, which is a national top 50, especially if you try the SF Working Professional Exec programhttp://www.gsm.ucdavis.edu/ProspectiveS ... itemid=228
But still, I'd throw an app at Haas and visit CSEB before I made any choices.
