Bettendorf Alderman Gary Mohr will step down from his at-large council seat Dec. 31 following his election to the Iowa House of Representatives in last November's general election.
The resignation creates a one-year vacancy, which can be filled by either an interim appointment by the council or by a special election.
In accepting Mohr's resignation letter at its Nov. 15 meeting, the council did not discuss which method the city would choose to fill the opening.
Mohr was elected to the four-year term in 2013.
In the past, the council has opted to schedule special elections to fill vacancies, utilizing consolidated voting locations to minimize the expense of election personnel.
Mohr resides in the city's 5th Ward, but the at-large position represents the entire city with all residents able to cast a ballot in any special election.
Mohr won election to the state house as a Republican, filling the seat vacated by Republican incumbent Linda Miller, who decided not to seek re-election.
