I am sorry, I didn't read carefully enough. In the realm of just gear and supplies:
String and rope (shelter construction and rescue)
Plastic sheeting and shelters
Water purification materials and equipment (Filter, purify and store; bleach, pots for boiling, cloth or coffee filters for filtering)
Enough food for about 1000 calories per person per day (bulk dry or canned storage)
Medications (known needs and treatment for things that arise; have hard copy medical references handy)
Sanitation and cleaning (bleach, alcohol, soap; TP would be nice, but be prepared to improvise)

Shelter, water, health and food; beyond that you will have to scrounge and build. Unless you are storing in a warehouse and you can afford to fill it.
