Wrigley Field is getting a $300 million makeover, per Jon Greenberg of ESPNChicago.com.

After a 4 1/2 hour meeting Thursday, the Commission on Chicago Landmarks unanimously approved most of the Chicago Cubs' plan to renovate the stadium.

Part of the project on the local landmark is still up for negotiation—namely the 6,000 square-foot video board in left field and the 1,000 square-foot sign in right field.

The videoboard and sign meeting will come July 11 during the regularly scheduled landmarks commission meeting, as Thursday's meeting was only a special meeting at City Hall.

"We are happy the landmark commission approved our plan today," Cubs spokesman Julian Green said. "Obviously we still have more work to do and seeking additional approval for project. We think today is great step for creating momentum for the $500 million investment."

The approved portion of the project, which is said to take five years to complete, includes new exits, a greatly restored exterior to the stadium, outfield and upper deck patios, a new LED board in left field, a refurbished press box and suite area, expanded dugouts and clubhouses, more restaurants, concession spaces and restrooms and enclosed bullpens.

Tom Tunney, alderman for the 44th ward, which includes Wrigley Field, is still concerned about the size of the videoboard. He wants both the videoboard and the sign to be smaller.
