They have been doing work, but given the scope of effort needed to harden the entire state, it's a monstrous task.
FPL replaced all or most of the overhead poles in my area with gargantuan concrete pillars. They replaced all of the underground lines. And they also have kept trees which would interfere with overhead lines trimmed back on a regular basis.
Due to the above, none of the residents in my neighborhood lost power during the storm, not even for a single second. Believe me -- it was a welcome change from my experience with Wilma when my neighbors and I lost power for nearly 3 weeks!
Unfortunately, it sounds like they didn't yet get around to hardening your area. I think my neighborhood got priority, since our lines were already in bad shape. Up until about 2 years ago, we would lose power roughly once every couple of months, sometimes for over 24 hours. It was ridiculous.
