CHICAGO -

The squabble between the Chicago Cubs and the owners of the rooftop venues that peek over the walls of Wrigley Field is heading back to City Hall.

The Cubs will ask the city's landmarks commission Thursday to approve a massive $500 million renovation project that is even more extensive than the project that the same commission and then the City Council approved last year.

The Cubs are pushing for five more signs to go with the Jumbotron and another video board in the outfield.

Rooftop owners are expected to oppose the proposal. The signs would affect views of the field that the businesses depend on, and potentially violate the revenue-sharing contract the rooftop owners have with the team.
