The Urban Environment League is a non-profit organization originally created in 1996 under the leadership and guidance of Gregory Bush, a professor at the University of Miami's History department and the Institute for Public History. The organization is dedicated to promoting safe and responsible practices in urban development in Miami-Dade through education and by advocating for environmental reform and legal protections for historical landmarks. Their records contain several issues of their internal newsletter, the Urban Forum; membership lists; minutes; correspondence; pamphlets; flyers; brochures; periodicals; research files on historical landmarks in Greater Miami, and urban planning; financial records; administrative files; ephemera; audio-visual materials (floppy disks and negatives); and legal files.
