Township trustees have discretionary, executive and judicial functions. They may, at their discretion, adopt certain regulations as allowed by state law. For instance, they may regulate engine noise and vehicle parking, and noise from a bar that serves liquor. Trustees may establish regulations for fire and police protection. The township trustees are the executive officers of the township. They are responsible for appropriating township funds, and they are the township taxing and purchasing authority. They hold title to and are responsible for the physical property of the township. They may own such facilities as parks and cemeteries. Township trustees may hire personnel and enter into contracts as necessary to perform their duties.
