A five hour meeting of the Plan Commission Thursday included a 30-day deferral of a nearly 300-unit residential development near O’Hare, though the local alderman wanted it held “indefinitely”; opposition from West Town residents who don’t want the city to sell land for affordable housing; a presentation from the University of Chicago on a new 97,000 sq. ft. lecture hall; and approval of a zoning change to allow a Lucky Strike, movie theater and health club at the two-acre Clark and Addison development near Wrigley Field.
