Harris plans to spend about $30 million on development at the former SEFOR (Southwest Experimental Fast Oxide Reactor) site.

  • It'll be called the Devil's Den Proving Ground, a nod to its state park neighbor.

State of play: Renowned local firm Marlon Blackwell Architects is designing the site, which includes an original Warren Segraves building.

  • A walking trail, ponds, sleeping accommodations for customers, a commissary and a helicopter pad are in the plans, Harris said.
  • The first phase should take about 18 months to complete and should start by the end of this year.
