Luxury community planned for doomsday scenario

A Texas developer is planning a 300 million dollar luxury compound outside Dallas, but most of it will be underground.

That's because Trident Lakes is a bunker community, designed to survive a doomsday scenario.

It will have about 400 condos with ninety percent of their living space   underground.

The developers say as many as 1600 residents could live there.

A California-based group already has six such developments.
