A bill for an act relating to county supervisors, concerning county supervisor representation plans and county supervisor vacancies, and including effective date provisions.

HF 786 requires counties with a state university campus governed by the Iowa Board of Regents to use "Plan Three" for electing county supervisors, rather than other representation methods. It also establishes that counties with populations over 125,000 or university campuses must fill supervisor vacancies through special elections, while smaller counties without universities may use appointments. The bill mandates counties using "Plan Three" to create new district maps by October 2025, with plans taking effect January 1, 2026. It applies immediately upon enactment and affects how 30+ Iowa counties handle supervisor elections and vacancies.
