Didn’t City Council recently vote to cut the debt-retirement millage in half?

Yes, but this millage is a floating millage, which would allow City Council set the level to whatever it deems necessary. This means it could still collect the entire amount were the new millage to pass, and even raise the millage to pay for additional debt, without a vote of the people. The decision to “cut the millage in half” is not binding and might be a bait-and-switch strategy, to increase the odds of passing the two measures without actually providing relief.
