The roughly $6 billion operating budget for Chicago Public Schools would mark a nearly $285 million spending increase from last year, and includes about $60 million in extra funding for schools to help cover unionized teacher salary increases.

Nearly a third of property taxes now collected by City Hall go into 143 special taxing districts controlled by Mayor Rahm Emanuel and aldermen, according to a new report by Cook County Clerk David Orr.

Orr said a record-high $660 million poured into tax-increment financing funds last year, which was more than 31 percent of the $2.1 billion-plus that city government collected. The veteran clerk called the percentage “stunning.”

In a statement, state Sen. Sam McCann, a Republican running for governor on the Conservative Party line, announced that he has filed legislation to reverse the $180 million appropriation on grounds that there are better uses for the money than dropping it on a “high-profile luxury project.”

The agreement, which apportions previously withheld and future tax revenues between the involved parties until the city’s debts are paid in full, resembles an interim pact reached last month as Harvey scrambled to make payroll and pay for essential services.
