"All we really need is to be able to run our business like a business and not a museum," Ricketts told the audience.
One of the rooftop owners, Beth Murphy, sat in on the speech and told reporters afterward that it was the first time she'd seen any drawings of the screen and that she and other owners would have a lot of vetting to do before determining if the proposal works.
"It looked big to me and it looked like it blocked out the neighborhood," she said.
The rooftop owners have previously threatened legal action, and Murphy said she was confident their contract would hold up and protect their businesses.
Ricketts said the team formally filed its renovation proposal with the city of Chicago on Wednesday. The plan must get approval from city planners and the City Council. There will also be public hearings on the plan.
