The Board of Trustees serves as the legislative branch of Joliet Township government. Every Illinois Township elects four trustees at-large and a supervisor who together comprise the Township Board. Each member has one vote on all issues brought before the Board.
In their capacity as legislative officers, the Trustees:
- Adopt the annual township budget and appropriation ordinance, the general assistance budget and the road district budget.
- Responsible for approving all township expenses and auditing bills submitted for payment by the highway commissioner
