To protect the ability to view the night sky and conserve resources, the city of Ketchum passed a law known as the “Dark Sky Ordinance” in June of 1999. The ordinance regulates exterior lighting by requiring lights to shine downward only and reduce glare. Dr. Stephen Pauley, a local retired physician, was the visionary behind the ordinance. The town focused its efforts on an aggressive awareness campaign for businesses and residents, and provided inexpensive ways to change current fixtures.
