On the plus side maybe and hopefully the Navy learned from past mistakes for not having needed yard times during the first Gulf War. The only other permanent carrier port on the east coast is Mayport, Florida and I think it is a one carrier pier from what I remember.
These sound like the needed three month down times between deployments ships require. A carrier maintenance cycle is a one year overhaul every 5 years plus a three month yard period after each 6 month cruise. It takes from the yard to a deployment about 6 months of work ups for training before the six month deployment.
I vaguelly recall that there were five visible from the interstate a few years ago. But maybe it was four. They were quickly moved, however.
