(and they have an on-going beach replenishment effort as well)
It's not the Pacific coast communities you have to worry about like Half Moon Bay or Santa Cruz. They have a beach, and then cliffs, and then the actual city is like 50-100 feet above sea level.
It's the bayside communities. Foster City. Redwood Shore. The Embarcadero. SFO. Port of Oakland. Highway 101.
All of these are pretty critical parts of Bay Area infrastructure, and gone with as little as a 1.6' sea level rise + 20yr storm.

This work has to be done for good reason, but looks like they're on it?

The Bay Bridge channel is so shallow it has to be dredged. There was a 1946 plan to fill it in.[1] There were Corps of Engineers plans for a lot of filling, but they didn't go that far. I have a copy of their 1960-2020 plan for the Bay Area.[2] Their vision was to make the SF bay area a major industrial city, building on the facilities built for WWII. Aluminum smelter in Sausalito. Steel mills at Tiberon. Five freeways up the Peninsula (101, 280, 35, 1, and one on stilts in the bay.) Another Bay Bridge. Maybe a SF-Alcatraz-Angel Island-Tiberon link. It would have been like Pittsburgh.
