Incumbent Mayor Les Fillingame and challenger Mike Favre will face each other in the runoff election May 16.
There was only a 22-vote difference between the two.
There also will be a runoff for councilman at large between Democrats Mike Weems and T.J. Collier. The runoff will decide the race as there is no Republican challenger.
Democrat Carol Strohmetz defeated incumbent Wendy McDonald in Ward 2, and incumbent Jeffrey Reed held onto Ward 3. Neither faces a challenger in the general election June 6.
Democrat Tad Black and Republican Kyle Lewis, both political newcomers, won the Ward 4 primaries and will face off in the general election.
The Ward 1 race also will be decided in the general election between independent incumbent Doug Seal and Republican George Williams.
