As the Northeastern region of Illinois began experiencing remarkable growth over the past two decades, local leaders recognized the need for unified area planning to support and manage the effects of this growth in individual counties, as well as the entire region. In 2005, the Chicago Metropolitan Agency for Planning (CMAP) committee was formed to create regional strategies to address transportation, housing, economic development, open space, the environment, and other quality of life issues. A subcommittee, the Council of County Board Chairs, is comprised of county leaders, and regional and local transportation officials and provides a forum to develop these plans cohesively.
