Sand gets brought in. Some of the beach loss is erosion due to higher tides, some of it is wind.
Nobody talks about it much, but Market Street at the Embarcadero has flooded at least 3 times due to high tides since I've lived here.
And per this article even more often than I remember.

@Animeraider I’m familiar with the King Tides project. Yes… this is going to be a problem … all around the world and observing what happens at King Tides is very valuable … esp in high population areas where there is critical infrastructure. Some don’t take sea level rising as seriously as they should. It will displace millions.
@Museek I live about 50 feet above sea level, which is actually higher than Market street. I'm paying attention.
@Animeraider I would be, too!
@Animeraider wow… how?
