Democrats Doug Fleshman and Dana K. Hayes and incumbent Republican Harold Craigo are running in the Second Ward Race.
Incumbent Democrat Tom Bailey and Republican Connie Thompson are guaranteed seats in the Third Ward race because no other candidates filed.
The same is true in the race for Fourth Ward, where only Sullivan and fellow Democrat G.L. Harper are running.
Polls are open 6:30 a.m. to 7:30 p.m.
In other business, Fire Chief Butch Ellis announced that 16 new disaster sirens would be tested on the fourth Wednesday of each month at noon.
"Not only does it siren, it will give you an audible warning of what is going on after the initial alert," Ellis said about the new systems.
Ellis went on to say that Metro and county coordinators are looking for feedback from residents. They want to know if residents can hear the siren and if they can understand the message that follows.
Ellis urged residents to contact him after the next test with their feedback.
