The University of Chicago is proposing that the Obama presidential library be built on about 20 acres of South Side parkland, either in Washington or Jackson parks, according to the university.

The two sites are:

•21 acres in western Jackson Park, bounded by South Stony Island Avenue to the west, South Cornell Avenue to the east, East 60th Street to the north and East 63rd Street to the south.

•22 acres in western Washington Park and 11 acres outside of it, stretching as far west as South Prairie Avenue, and encompassing the Garfield Green Line stop. The park acreage is bounded by South Martin Luther King Drive to the west, Ellsworth Drive to the east, East Garfield Boulevard to the south and East 51st Street to the north.

Chicago Tribune story

Unbelievable. Apparently "park" is a Chicago term meaning "landscaped area where we haven't yet thought of anything to build."
