Right off the top of my head:

What are the likely and unlikely threats that you and your family may face. Which threats demand Bugging Out for and which threats don't demand Bugging Out for.
(Look @the Log Term Preparation Board for the ThreatCon and HurCon Checklists) It may help.

Consult www.standeyo.com for checklists of supplies. I think you will find it helpful.

You need to decide what situations it is best to stay put (and how long you can stay put) for and what situations it will be necessary to bug out from.

If you're staying put, you've got to plan on providing the basic services that allow you (and your dependants) to consume water, prepare & serve meals; go to the bathroom, defend yourself, family, & property; getting Intel (reliable news).

If you're Bugging Out, you need to have completed recon and mapped out several routes leading out of the city. You will need to identify possible dangerous areas along those routes and plan on how to deal with those areas/threats. You will need to know where you're going to Bug Out to, what supplies you can take with you (or have supplies cached at your destination or along the way), and again, how are you going to provide the basic services that are required for living once you arrive at your destination.
