he Chicago Park District is so short of funds it’s cutting programs, raising fees, and telling community groups that if they want a playlot, soccer field, or running track, they’ll need to raise the money themselves. Nevertheless, it has somehow found roughly $22 million to spend on Streeterville real estate for its central office. The district has been renting there since 2001, and officials say the conversion to ownership, which the board approved in February, will save about $720,000 a year in property taxes.
