This looks like a good start! My question, though; what disasters are you aiming to prepare for? Perhaps a list can help to tailor some preparations;
- Hurricane (days-weeks or more)
- Flood (days, perhaps weeks)
- Blizzard/Ice Storm (days)
- Volcano (SIP doubtful)
- Avian flu (12-18 months)
- Tsunami (days)
- Nuclear air burst (months)
The type of disaster will greatly affect the breadth and scope of preparations.
