Depending on increased Arctic and Antarctic glacial instability the rates could well accelerate even more.

James Hansen & colleagues at Columbia have published very detailed analysis based on partial analogy with the Palaeocene-Eocene thermal maximum (very roughly same CO2 levels as today) suggesting that short term (say 100yr) rise could be quite a few feet, and long term (say 1000yr) rise could be over 200 feet.

Try drawing say 10 and 200 ft elevation contours on the eastern seaboard and Gulf!
