A wildfire that destroyed 11 Spokane Valley homes last week grew out of an illegal recreational fire that a local surgeon supervised three days earlier on her neighbor’s vacant lot, a fire official said. The “unapproved, unextinguished recreational fire” was set July 7 on a wooded parcel next to the home of Tracy Berg, who lives at 1915 S. Eastern Lane, according to Bill Clifford, deputy fire marshal for the Spokane Valley Fire Department. The fire was made in an old stump that had been repeatedly burned, which made it a fire pit, he said.
