Computing and revamped Lewis College of Science and Letters, the School of Applied Technology and College of Science were dissolved. Today In 1994 the National Commission on IIT considered leaving Mies Campus and moving to the Chicago suburbs. Construction of a veritable wall of Chicago Housing Authority high-rises replaced virtually all of Illinois Tech's neighbors in the 1950s and 1960s, a well-meaning but flawed attempt to improve conditions in an economically declining portion of the city. The closest high-rise, Stateway Gardens, was located just south of the Illinois Tech campus boundary, the last building of which was demolished in 2006. But the Dearborn Homes to the immediate north of campus still remain. The past decade has seen a redevelopment of Stateway Gardens into a new, mixed-income neighborhood dubbed Park Boulevard; the completion of the new central station of the Chicago Police Department a block east of the campus; and major commercial development at Roosevelt Road, just north of the campus, and residential development as close as Michigan Avenue on the east boundary of the school. Bolstered by a $120 million gift in the mid-1990s from Illinois Tech alumnus Robert Pritzker, former chairman of IIT's board of trustees, and Robert Galvin, former chairman of the board and former Motorola executive, the university has benefited from a revitalization. The first new buildings on Mies Campus since the "completion" of the Mies Campus in the early 1970s were finished in 2003—Rem Koolhaas's McCormick Tribune Campus Center and Helmut Jahn's State Street Village. S. R. Crown Hall, a National Historic Landmark, saw renovation in 2005 and the renovation of Wishnick Hall was completed in 2007. Undergraduate enrollment has breached 3,000. To further boost their focus on biotechnology and the melding of business and technology, University Technology Park at Illinois Tech, an expansive research park, has been developed by remodeling former Institute of Gas Technology and research buildings on the south end of Mies Campus. Academics Academic units Illinois Tech is divided into five colleges (College of Computing, Armour College of Engineering, Lewis College of Science and Letters, College of Architecture, Chicago-Kent College of Law), an institute (Institute of Design), one school (Stuart School of Business), and a number of research centers, some of which provide academic programs independent of the other academic units. While many maintain undergraduate programs, some only offer graduate or certificate programs. In 2003 Illinois Tech administrators split the former Armour
