All four Ward positions will be up for election this fall. Tomorrow is the last day to submit an application to run. According to the City Clerk's Elections page:
So far, Wards 1 and 4 have only one candidate each (Emily Kurzinski and Sandra Knect, respectively). Ward 2 has two candidates (Gerchard Pfau and Daniel Sung). Ward 3 has three contenders: Don Cameron (incumbent), Loretta Huff, and Brad Prince.
If you're still thinking of running, you have until 5PM tomorrow, August 25th, to turn in your petition with a minimum of 25 valid signatures.
