A Chicago firm is suggesting the Alliant Energy Center campus be redeveloped to create a “village feel,” while renovating and expanding existing structures including the Dane County Coliseum.

Robin Hunden, CEO of Hunden Strategic Partners, on Friday presented a report to the Alliant Energy Center Strategic Design Study committee. It evaluated current uses of the center and projected the economic impact of an improved center, including data from similar centers across the country and input from current and potential users.

The redevelopment would have a price tag of more than $240 million if all of the suggested renovations and expansions were made, but Hunden said the center could increase its full-time employment positions by more than 600 and bring more visitors to boost the local economy.

The Coliseum would require the biggest improvements, with a cost of $87 million to $105 million depending on how many amenities were added, which is roughly half of the price to demolish and rebuild it.
