All you Hams should join your local RACES/ARES.
They gave me a very nice FEMA "Emergency Communications" ID card and I enjoy doing the volunteer work. Met some good folks.

Or if you have a local CERT, that's another good organization to consider. Also administered under FEMA.

Fort Worth RACES training is a 4-hour class and background check, in addition to being a licensed radio operator. They have a monthly on-air training/check-in that's usually a half hour or so. Other locations will have different requirements, but nothing too onerous.
CERT training is more extensive. Typically 30-40 hours of classroom, plus monthly meetings to stay active. Again, different localities will have different requirements, but the curriculum is laid out pretty clearly by FEMA. Check your local area...
