Do you know your community’s operations plan for emergencies? If not , you should.
If you are planning on the local / state / national government entities to restore services to you after an emergency you should inquire about the plan for making it happen.
There are many resources for preparedness information. One place to start is ready.gov
Where else have you found information? If you have found other places that would be helpful leave a website or link in the comments.
When the moment of truth arrives, the time for prior planning has passed. Is there a plan?
