The whole city doesn't have to flood for things to get pretty grim. As an example, take a look at Pacifica, which also shows very little flooding on that map, yet has already had to start demolishing buildings as coastal cliffs erode. Also, if you look down the peninsula, heavily populated areas start to look pretty wet pretty fast. That's not going to be good for the area as a whole.
