Depends on motivation and power structure I would think. These are incredibly productive institutions and under normal operation can build enough resources to weather any storm, plus this kind of thing is what's mainly insured when a storm does hit. In response to a gradual rise in sea level, they would be expected to adapt at a glacier's pace but anything is possible. For example the island of Galveston was largely raised 8 feet after the disaster of 1900 as the preferred approach to future mitigation, and that foresight turns out to be about as good as you can get so far when it comes to coping with unforseen sea level rise. You just need to have foresight good enough to forsee the unforseen. Eventually working in industrial environments like Galveston or Texas City will not be that much different than working offshore in the Gulf. Heck, some operators justify working offshore now because it's not much worse than working in a mainland oil field or refinery anyway. Besides traditional businesses of Texas, in South Florida probably agriculture and real estate would suffer first, but I imagine tourism would hold out as long as it could and smuggling would not want to go anywhere either, with their multi-century tradition.
