In October 1975, the first floor layouts of the Rapid City Civic Center (now the Rushmore Plaza Civic Center) made their public debut. According to the Rapid City Journal, the displays of the building included layouts of three levels, square footage of the convention space, and the seating capacity of each area. Color photographs of the renderings were on display at several businesses located throughout the city.
Promotional materials were also produced to get the word out about the new convention space in particular. A facilities book, brochure, slide presentation, and a traveling suitcase model of the arena were used to promote the facilities to potential patrons. A model of the Civic Center was also planned for placement at the airport for incoming travelers to view.
