Chicago began demolishing its crime-ridden, dilapidated public housing high-rises in the mid-1990s. By 2000, the city had launched the ambitious Plan for Transformation, aiming to replace 38,000 public housing units with new or rehabbed mixed-income units in 10 years. But 15 years later, the Chicago Housing Authority is still working to complete that goal.

The Chicago Housing Authority's Cabrini Green homes stood for decades on the Near North Side. Between 1995 and 2011, the buildings were demolished and replaced with mixed-income housing. The new documentary "70 Acres in Chicago" tracks that tumultuous period and the efforts of residents to save their homes.
