Chicago and Cook County could save $11 million next year by working together to deliver services, according to a report released today.

After several months, a seven-member city-county panel concluded that making a substantial financial impact will take time. In the group's initial June report, it estimated the city and county could save up to $140 million by 2014.

The largest anticipated savings for 2012 will come from pooling custodial services for a projected savings of $4 million, and having vendors bid once for city and county work, to save an estimated $2.9 million.
