Election Information

The Mayor and City Councilmembers are elected for four-year terms in Regular Municipal Elections, with one Councilmember elected from each ward every two years and the Mayor elected every four years (2023 and 2027). Regular Municipal Elections are held on the first Tuesday in November in odd-numbered years.  This year citizens will elect one Councilmember from each of the four Wards. The terms of Councilmembers will begin on the first Council meeting following their election and continue for four years. The Mayor presides over Council meetings and is the recognized head of the city government for all ceremonial purposes. The Council chooses by majority vote one of its members to be Mayor pro tem. The Mayor pro tem, in the absence of the Mayor, will perform the duties of the Mayor. The City Clerk's office is responsible for conducting the Municipal Elections, as well as assisting Adams County with registering citizens to vote.
