RAPID CITY, S.D. (AP) — Rapid City Mayor Steve Allender has formed a task force to study the future of the Rushmore Plaza Civic Center.

The facility needs $73 million in upgrades to meet Americans with Disabilities Act standards. Residents in March rejected a $180 million proposal to expand and upgrade the facility.

Allender in October assembled a 17-member advisory committee, and on Wednesday he announced the formation of a task force "to develop and sift through options."

The group will meet throughout next year to develop a plan.
