The original version of our Nov. 17, 2016 interview with Ben Joravsky, "Trump and transit: Rahm railroads Red Line appeal," contained an error.

Reporter Dave Glowacz said that the city's consultant estimated that the Red Purple Modernization Phase 1 TIF district will generate $17.6 billion in tax-increment revenue. That was incorrect.

The consultant's report says that the district will create a total increase in properties' equalized assessed valuation (EAV) of about $17.6 billion over 35 years.

To calculate the amount of tax revenue associated with the total EAV, multiply by the county's current tax rate, .0687 (6.876 percent), by the EAV in each year of the district's 35 years.

That yields a very rough estimate, as the county's tax rate changes year to year.

We've corrected the audio tracks for the interview.
