I don't know what your source is for the 2 ft number, as any predictions of future sea level are dependent on emissions scenarios. Further, sea level is local--that is, different areas of the world will experience different amounts of local sea-level rise in the future, based on regional conditions.

In south Florida, the estimated sea-level rise for the intermediate-high emissions scenario is approximately 5.5 feet by 2100. Attaining 2 feet of SLR requires an intermediate-low scenario. The high scenario results in 7 feet.

Storms will also get worse and more frequent, so I assume storm surges will get worse as well.

Worse and less frequent

I was imprecise. I meant the worse storms would get more frequent. My point was that more frequent bad storms combined with modest sea level increase meant greater chance for overrun compared to just the sea level increase.

This is noted in the document you linked to, where they mention most of the models project an increase in of Atlantic hurricanes reaching Category 4 or 5 even at an optimistic 2 degree C rise. They do note it's somewhat uncertain though, I'll give you that.
