Representatives from the K Maretta Coliseum Exhibit Hall presented renovation and expansion plans at Acworth City’s Feb. 16 work session, saying the venue has rebranded and is positioning itself for future convention and performance business.
Karen, introduced as the venue’s director of marketing and social media, said the authority recently rolled out a new logo and changed its name to emphasize the facility’s convention role. The presenters described recent work that reopened the building after a four-month shutdown, citing improvements including new bathrooms, lighting, carpet and a renovated ballroom. Rob, who handled finance details, said the total project is estimated at $190 million and is funded through a bond issue that closed in July 2021 plus authority reserves.
The presenters described a phased expansion that would add about 13,000 square feet of meeting space and bring the facility’s total cited footprint to approximately 377,000 square feet. Planned features include a new arrival plaza and primary entrance, a new parking deck to replace a demolished red-deck structure, an internal courtyard, a grand staircase and new food-and-beverage concepts. The presentation also showed a proposed bridge connection to the 285 corridor and mentioned the possibility of an outdoor restaurant near the entrance.
The presenters said the venue has operated for more than three decades, noting roughly 23,000 events since 1994, attendance totals cited in the presentation (13.1 million) and a multi-year economic-impact figure stated as about $4 billion to the county and state. They also said venue operations supported more than 1,000 jobs in 2024. Council members asked about access and circulation; presenters confirmed pedestrian access would be direct from the new section when it opens.
The presenters played a fly-through video of the renovated space and invited council members and staff to schedule follow-up tours. No formal action was taken; the presentation served as an informational briefing ahead of any permitting or formal approvals.
