you might consider setting up a phone tree (tree phone) with redundancy. All you need is to be able to contact just one person in the tree. Definitely good thing to have things for granted to be reiterated.

Also consider what happens if you are unable to get power to recharge your portable equipment. Can you recharge from your car? and if your car is flooded out, can you still recharge your cell? And always have a pair of boots, and pair of heavy glove. After a disaster, area may not be safe to be walking around in thin tennis shoes or dress shoes. More people get injured from the debris was what I was told in disaster training.
