Redistricting Johnson County
Johnson County is divided into six commissioner districts. The goal is to keep the districts “as compact and equal in population as possible.”
Redrawing the voting district lines, also known as redistricting, was needed in 2025 because the current districts varied in population by 11.2%. Redistricting is required when population variation goes over 10%. The county’s previous redistricting was done in 2013.
During the 2025 redistricting process, the Board of County Commissioners developed three draft maps, gathered input from the public and voted to adopt a new district map. View a timeline of the process below.
Timeline
- April 3: Committee of the Whole to discuss draft criteria
- May 8: Committee of the Whole - presentation of draft maps
- May 22: Committee of the Whole - further review of draft maps
- June: Public input meetings (one in each district and one held virtually)
- July 24: Committee of the Whole to choose map
- July 31: Board action to formally adopt new map
- Aug. 14: Final maps delivered to the county
Adopted Map
At a Committee of the Whole meeting on May 22, 2025, the Board of County Commissioners forwarded three draft maps for public input as part of the redistricting process.
On July 31, 2025, the Board of County Commissioners voted to adopt a map that assigned just over 18,500 residents into a different district. With the boundary adjustments, the districts will vary in population by only 4.39% and should not need to be redrawn for at least five years.
Public Engagement
In June 2025, Johnson County held six public engagement meetings (one in each district) as part of the redistricting process. The sessions allowed members of the public to learn more about why the county was redistricting, ask questions, share thoughts and view proposed maps of redrawn county commission districts.
In addition, a virtual public engagement "lunch and learn" session took place on June 11 from noon to 1 p.m.
