Just north of the Golden Gate Bridge, yet a world away from San Francisco, in an unincorporated and oft-overlooked area known as Marin City, sea level rise is rarely the first worry that comes to mind.

But sea level rise is a lot more complicated than just waves breaking over seawalls and beaches disappearing.
