The Storm Prediction Center of the National Weather Service includes maps, tracks, averages and summaries that apply to tornadic activity in the United States. The Norman office of the National Weather Service keeps a historic list of tornado data by county. The EF Scale became operational on February 1, 2007 and is used to assign a tornado a 'rating' based on estimated wind speeds and related damage.
Construction on the $40 million project began in 2008 and is located seven miles northwest of downtown on 240 acres. The land was donated by Gentner Drummond and Tom Atherton.

The master plan calls for 15 major theme gardens, 60 specialty gardens, a 3,000-seat amphitheater, a conservatory, an education complex, an interfaith chapel, and a three-story observation tower.
