Tuesday is Chisholm Mayor Todd Scaia's last day in office.
This comes after a surprise announcement in December that he would be resigning after much thought, and deliberation.
Scaia has served the city since 2003, the last six years of which had been on the council.
As president of the city council, Scaia became the acting mayor after former Mayor Michael Jugovich was elected to the Saint Louis County Board of Commissioners in 2016.
Chisholm will have a total of four offices up for election in 2018.
It's unclear who will replace Scaia in the interim. Several calls and e-mails to the mayor's office were not returned by news time.
