"Is Foggy Bottom another name for the State Dept.? "
Yes.
DC is built on a swamp, and State is nearly adjacent to the Potomac River. So the small landmass from State down to the Lincoln Memorial - just a couple hundred yards really - tends to be a fog (humidity) sump.
I was away cooking dinner, see you received an answer.
