The Navy estimates it would cost $50 million to dredge 5.7 million cubic yards of sediment and up to $370 million to build the shore and pier infrastructure.
We don't need every undeployed carrier sitting in NORVA. Mayport used to be one of our liberty ports. KENNEDY was homeported there in the 1970's IIRC and in 1980 we got orders for a homeport change to Mayport that I think Cap Weinberger later rescinded. Not sure about that I was off ship by then.
