In 1989, Ukeles was commissioned by the Fresh Kills Landfill in Staten Island, to work on the reclamation project to transform the 2200-acre, largest manmade site, to a recreational park known as Freshkills Park. Ukeles invited New Yorkers from all five boroughs to contribute palm-sized artworks made of trash. After the September 11, 2001 attacks on the World Trade Center, Fresh Kills was used as a temporary sorting facility for rubble and remains.
