That Neustar list is horribly outdated from 2009 and didn't list sf.ca.us and had scruz.net as the administrator for san-francisco.ca.us.
I checked www.whois.us and oakland.ca.us is administered by locality-support [at] about [dot] us
Try sending them an email?
That indicates that approval has been rolled up into GoDaddy at this point, and you’ll have to get a notarized letter from the city for them to issue you a domain.
Just saw your other comment here. That's a bummer. I've been lucky to have never dealt with GoDaddy.
Any idea who the current SF registrar is?
Yup! Sonic.net
`whois sf.ca.us` will give you the email of the registrar (thanks cogitosum).
