The Macomb Athletic Conference was formed in 1986, and began competition in September 1987. The seventeen charter member schools included ten from the Macomb Athletic Conference and seven from the Bi-County League. The league was renamed the Macomb Area Conference because member schools were now located in Macomb, St. Clair and Wayne Counties.
