5. “Against Babylon” by Robert Silverberg
At first this reminded me lots of his story “Hot Times in Magma City” which I’d read in the first volume of Year’s Best SF from nearly a decade later. Both follow fire-fighters in LA, albeit in the other responding to volcanic activity and in this case clumsy aliens.
Another story of culture clash within the US, the whimsy quirkicality of the Bay Area against the stolid, down-to-earth interior and the gulf of values and understanding between them.
