The preferred design for an expansion of the Rushmore Plaza Civic Center in Rapid City involves a westward expansion of the facility's Barnett Arena and an attached parking garage.
The $180 million design would expand arena seating from 9,400 to 19,000. The arena would be large enough to house an indoor football field. The multilevel parking garage would have room for 1,000 vehicles, though construction would eliminate 500 existing parking spaces.
Officials completing the design work are expected to present a final recommendation to the Rapid City Council on July 7.
