In collaboration with landscape architect James Corner, the city in 2009 began to explore concepts for a redesign of the square. In October 2011, Cleveland mayor Frank Jackson proposed his plan to redevelop the square, which included closing Superior Avenue and Ontario Street to create a large green space in the center. On October 23, 2014, the Cleveland Landmarks Commission approved a plan which closed Ontario Street but kept Superior Avenue open to bus traffic, and kept the Soldiers' and Sailors' Monument prominent.
