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.

Aldermen approved the plan in a 26-23 vote a day after Mayor Brandon Johnson’s administration proposed a version with clearer spending guardrails.

But the mayor was forced to cast another tie-breaking vote to avoid having the decision on his bond issue put off even longer.
