CHICAGO-A recent plan floated by the Chicago Cubs to privately pay for $300 million in improvements to Wrigley Field is just one of a number of ideas being discussed to finance the project.

Chicago Alderman Tom Tunney, who represents the 44th district, did not rule out relaxing city advertising regulations and easing city landmark rules that make it difficult for the team to erect lucrative billboards, which is part of the proposal by Chicago Cubs CEO Tom Ricketts to pay for the entire rehab project. A previous plan to use public amusement tax revenue was not warmly received by Chicago Mayor Rahm Emanuel, according to the Chicago Tribune.

“I think a lot of balloons are being floated,” Tunney said. “A lot of what they said has not been presented to the community.”

Tunney said Cubs officials would need to sit down with the owners of rooftop clubs that overlook Wrigley Field. The newspaper stated that rooftop club owners also expressed their opposition to new signs that might block their views. See story in the Chicago Tribune.
