It would allow the Cubs to put advertising on the clock in the centerfield scoreboard and along the top of the outfield wall.
The plan was approved as part of the broader Wrigley renovation package. But the proposal for a Jumbotron in left field and a large advertising sign in rightfield was pulled out. The signs have caused public debate among residents and Alderman Tom Tunney who think they are too big.
Mayor Rahm Emanuel took no sides by praising both Tunney and the Ricketts family.
"I think there's a way to upgrade Wrigley Field to the 21st century. And the Ricketts will also see that type of ability to that in a way that's complimentary to the entire field and stadium," Emanuel said.
Another landmarks commission meeting is planned for Thursday.
Wrigley Field turns 100 years old next year, and the Cubs hope to celebrate with a $500 million renovation of the historic ballpark and area surrounding it. On June 27, the team cleared its first big hurdle with approval from the Chicago Landmarks Commission.
"We think with this step, having this approval by the Landmarks Commission, really gives us an opportunity to move forward," said Cubs spokesman Julian Green last month. "It gives us some momentum to sit down with the aldermen and the city to come together with a plan that works."
It's a plan that many Wrigleyville residents and longtime fans like.
"To have someone come in and say, 'I'm going to spend $500 million to improve your community.' It is a no brainer," said Katie Kennicott.
