April 2022: Revised Ward Plan in the Works
New Ward Population Data Following State Mandated Ward Splits
The Common Council is preparing to establish a revised ward plan after the Wisconsin State Supreme Court adopted the Republican drawn maps approved by the state Legislature. Because by law the city cannot have a ward that contains two or more Assembly districts, wards must be revised to ensure there are no conflicts. The revised ward plan will be considered during the Judiciary and Legislation Committee meeting on May 2, and if approved will be before the full Common Council for adoption on May 10.

The Redistricting Process

The United States conducts a census of the entire population every 10 years. This information is used for many purposes, including the distribution of federal and state revenues and the drawing of boundaries for election districts at the federal, state and local levels.

Wisconsin law requires that once the census data becomes available, local governments and the state legislature are required to adjust the boundaries of election districts so that they are as equal as possible in population.

Due to the COVID-19 pandemic, the release of census data to the 50 states and, through them, local municipalities, was significantly delayed. When this data was received, the local redistricting process began. Counties are first required to develop a tentative supervisory district plan for their county boards. After that, municipalities are required to revise the boundaries of election wards and then their city council districts. Subsequently, school districts and the state legislature are also required to update the boundaries of their election districts.

For the City of Milwaukee the redistricting process was overseen by the Common Council’s Judiciary and Legislation Committee. They were supported by Legislative Reference Bureau staff trained in geographic information systems and redistricting laws and procedures.
