CLEVELAND — Cleveland City Council on Monday approved committing an estimated $88 million for upgrades to Quicken Loans Arena. Council’s vote approved the ordinance 12-5, meaning that it passed with emergency status. It takes effect immediately. The deal was the last piece of a package involving the city, Cuyahoga County, Destination Cleveland and the Cavaliers that will finance $140 million in improvements to the arena. The work at the arena would dramatically alter the facility’s appearance, creating more space for dining, bars and public gathering.
