The City Council narrowly approved Mayor Brandon Johnson's controversial $830 million bond deal to finance neighborhood infrastructure improvements, despite complaints that a back-loaded repayment schedule would inflate the total cost to $2 billion by the time all of the debt is paid off.

Mayor Brandon Johnson’s team is offering aldermen language clarifying that the money will not be used for purposes other than infrastructure repairs and upgrades.

The borrowing plan had been criticized for its structure, which pushes off paying down the principal until 2045. Some members of the City Council also expressed concerns over how the money would be used.
