Texas investors build community for doomsday scenario

A Texas investor group is planning for a doomsday scenario by building a $300 million luxury community replete with underground homes and air-lock blast doors designed for people worried about a dirty bomb or other disaster.

At the Trident Lakes community northeast of Dallas developers intend to construct about 400 condos that have 90 percent of their living space underground.

The community could have as many as 1,600 residents who can rely on water and energy production that's off the grid.

It's not clear just how many similar bunker communities are in operation. The Vivos Group, based in California, has six in the U.S.

The National Center for Disaster Preparedness says the bunker mentality complicates efforts to promote a broad, shared emergency response to disasters.
