Whether Evansville decides to renovate Roberts Stadium or build a new arena, it will be expensive. Consultant Tom Chema took questions from the Roberts Stadium advisory board Tuesday night. He said an 86-hundred seat arena that would be expandable to 10-thousand seats would cost anywhere from 40 million dollars for a low-end renovation to 75 million for a new arena. That doesnt include land acquisition or architectural and engineering fees. A state of the art renovation would cost 60 million dollars. Chema said hell have his final recommendation in February or March.
