For the
Ponte Vedra area (and St Johns County) you can try this link. It's not an intuitive site, but I think you might get the info you need about particular addresses and the flood zone they're in.
Click on this link

On the iMap page there are three tabs: Search, Layers, Legend.
First go to Layers.
Click on the Flood Zone folder and check-mark all three choices.

Enter the address, then click on whatever shows up in the Search Result(s).
