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.

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

After a one-week delay and calls for significant tweaks, the mayor's plan squeaked through the chamber on a 26-23 vote.
