Marshall County Lighting Ordinance


A few years back, park director Michael Stephan discussed the need for a county light pollution ordnance with Troy Kiefer, the previous Marshall County Plan Director. As a presumed result, a section on exterior lighting standards was included in the new zoning ordinance that became effective November 1, 2007.


The purpose of the lighting section is to provide standards for outdoor lighting that protect the public safety and the general welfare of the community by reducing unsafe and unpleasant lighting conditions, such as light trespass and light pollution, while also promoting the safe and efficient movement of vehicles and pedestrians and the security of local properties.

The complete Zoning Ordinance can be downloaded here.

The section on lighting standards is reprinted below:
