For the upcoming Primary and General elections, Story County will elect members of the Board of Supervisors by district, following changes mandated by Senate File 75 which passed in 2025.
Under Senate File 75, Story County will no longer elect its Board of Supervisors at large. Instead, voters will elect one supervisor from each of three districts. All three supervisor seats will be on the ballot for the 2026 Primary and General elections.
The Supervisor district map is as follows (District 1 highlighted in blue, District 2 highlighted in yellow, and District 3 highlighted in pink):
Populations:
District 1 - 32,783
District 2 - 32,894
District 3 - 32,860
To return to staggered four-year terms, initial term lengths were determined by a random drawing conducted by the Story County Auditor on January 27, 2026. Those initial term limits are as follows:
District | Initial term |
1 - blue | 2 years |
2 - yellow | 4 years |
3 - pink | 4 years |
The Iowa Legislative Services Agency prepared the district map. The Board of Supervisors approved the plan on January 27, 2026. The map is contingent on approval by the Secretary of State.
