You should have no power problems in Belmont and SF. Power in the built-up areas is not very vulnerable because it is underground or easily maintained and no built-up flammable debris is littering the ground (other than possibly dried poop in SF). The shutdowns are mostly in and around forested areas where they haven’t kept vegetation from intruding on the lines and where environmentalists have been resisting cleanup of dry brush, debris and dead trees.
I haven't been out to the Bay Area in 20 years. It will be quite interesting for me to see how SF and the area has 'changed'. My husband grew up in the East Bay and graduated from UC Berzerkeley (no, he was *not* a leftist hippie).
