features four relief panels sculpted in granite by John Flanagan. Each of the panels represents one of four principal concerns of city government: playgrounds, schools, parks, and water supply. As visitors enter the building, they are greeted with elaborate marble stairways and bronze tablets honoring the past city halls of Chicago from 1837 to the present. The first major renovation project undertaken was in 1967 as major city departments, originally located outside Chicago City Hall, were moved in. The "fifth floor" is sometimes used as a metonym for the office and power of the mayor – located in City Hall. Green Roof In 2001, roof gardens were completed serving as a pilot project to assess the impact green roofs would have on the heat island effect in urban areas, rainwater runoff, and the effectiveness of differing types of green roofs and plant species for Chicago's climate. Although the rooftop is not normally accessible to the public, it is visually accessible from 33 taller buildings in the area. The Garden consists of 20,000 plants of more than 150 species, including shrubs, vines and two trees. The green roof design team was headed by the Chicago area firm Conservation Design Forum in conjunction with noted "green" architect William McDonough. With an abundance of flowering plants on the rooftop, beekeepers harvest approximately of honey each year from hives installed on the rooftop. Tours of the green roof are by special arrangement only. The Chicago City Hall Green Roof won the Merit Design Award of the American Society of Landscape Architecture (ASLA) competition in 2002. In media The exterior and parts of the interior of Chicago City Hall were featured in the 1980 comedy film The Blues Brothers when the titular characters, Jake and Elwood Blues, race to the building to pay a tax deadline while being chased by a horde of police officers, firefighters, and the military. The interiors of Chicago City Hall were featured in the 1993 blockbuster movie The Fugitive, where Richard Kimble (played by Harrison Ford) is chased down the stairs by U.S. Marshal Samuel Gerard (Tommy Lee Jones), until spilling into the lobby, where Kimble narrowly escapes being apprehended by Gerard and his men.
