They have fleets of trucks and supplies set up well in advance, in position to respond as soon as the danger level permits.
When a disaster hits, they know if their stores are operational, power status, employee status etc.
They assist associates to relocate to new homes and get back to work if needed.
FEMA should model their set up after it.
I read just last week that Wal-Mart has the second largest fleet of trucks in the country.
Also, when Nagin and company were screaming about 10k dead, etc. Refrigerated trucks were routed to NO for body storage. We have so few refigerated trucks in this country that the move to NO caused severe refigerated food transport to other cities in the US...then, it turned out they weren't even needed in NO.
Nah, FEMA should just contract out disaster relief and coordination to WalMart. They'd do it better.
