In the aftermath of World War II, Anoka was reshaped by suburbanization as reliance on automobiles and the departure of businesses from the historic downtown brought changes in traffic management, business opportunities, and housing. Starting in the 1950's, a series of annexations from surrounding communities almost doubled Anoka's land area, and the city's population and government grew to meet increased needs. Federal Cartridge and the Olin Foundation presented a new City Hall to Anoka in 1956, when Charles Horn was president of both organizations, and through a series of additions the Anoka County Courthouse grew into the Anoka County Government Center in the 1990's. By 1963, the city had adopted a comprehensive Central Business District Plan to respond to the pressures of becoming a suburb. Anoka's businesses had evolved from supporting the logging industry in the early 1800's to supporting agriculture by the end of that century, and this adaptation continued in the 1990's as specialty shops, antique stores, and restaurants replaced grocery, hardware, and other traditional businesses. As Anoka prepared for the 21st century, plans aimed to improve the economic climate, enhance livability, and streamline local government.
