In contrast to the previous government structures, the 1935 charter, having taken effect in 1936, provided for all administration of city government to be headed directly by a single officer, the city manager, who was appointed by, and accountable to a city council of nine members elected as a group by the entire city at-large. The system was designed to address two principal issues with Saginaw's history of municipal government, the inefficiency and politics associated with having executive and administrative authority spread among many different officers and boards, and political rivalries and friction between various geographic areas of the city, mainly the east side and the west side.
