A bill for an act relating to county supervisors, concerning county supervisor representation plans and county supervisor vacancies, and including effective date provisions.
This bill modifies how county supervisors are elected and how vacancies are filled in Iowa counties, directly affecting county governments and voters. It mandates that larger counties, defined as those with a population of 125,000 or more or home to a main state university campus, must elect supervisors using "plan three." Under this plan, supervisors are elected by district, and voters only cast ballots for candidates within their specific district, with a transition plan for implementation by the 2026 general election. Additionally, the bill changes how county supervisor vacancies are filled: in smaller counties, vacancies will be filled by appointment, while in the designated larger counties, they will be filled through a special election. It also adjusts various timelines for special elections and redistricting processes.

MODERATE
This bill updates Iowa's county supervisor representation plans and election procedures, specifically requiring certain counties with state university campuses to use a specific representation plan (Plan Three). It also modifies vacancy rules for county supervisors and adjusts special election timing and thresholds.
Scope change
The bill expands mandatory use of Plan Three to counties with main campuses of state-regulated higher learning institutions, while adding exemptions for counties over 60,000 population from changing from Plan Three to other plans via special election.
REQUIREMENT
Counties with main campuses of institutions governed by the state board of regents must use Plan Three for supervisor elections.
Vacancy rules for county supervisors were updated to clarify when special elections versus appointments apply based on timing relative to primary elections.
TIMELINE
Special election petitions must be filed by June 1 of odd-numbered years, with elections held on the first Tuesday after the first Monday in August.
Transition provisions require affected counties to establish redistricting commissions by May 15, 2025, and complete precinct plans by October 1, 2025.
ELIGIBILITY
Counties with 60,000+ population cannot change from Plan Three to Plan One or Two unless approved by a two-thirds vote of ballots cast.
