Garland,

You are on the right track. Check HERE on FEMA's web site. I think that building a shelter in your basement is to way to go, just remember you will need an independent, reinforced roof in case the the ground level structure collapses.

Check with your local emergency management agency to see if they have any programs or helpful local information about contractors. Also check to see if they have a "safe room registration program". We are currently in the planning stages of building a new house and the county we have property in has such a program. This is how the program works: If you have a safe room or tornado shelter, you register your address with the EMA and if a tornado comes through your area, they will send personnel by to make sure you are not trapped by debris (special effort).

BTW, our property is in the dark orange area in Mississippi on this MAP.

Stay Safe,

JimJr
