Brigham City Council implements outdoor lighting standards to preserve dark skies

Brigham City officials have taken a significant step towards enhancing community safety and environmental sustainability by approving a new outdoor lighting ordinance during the June 5, 2025, city council meeting. This ordinance aims to regulate outdoor lighting standards, balancing the need for visibility with the preservation of the night sky and wildlife habitats.

The ordinance establishes specific guidelines for outdoor lighting fixtures, focusing on reducing light trespass and ensuring that light pollution is minimized. Key features of the ordinance include a maximum of 100,000 lumens per acre, which is deemed sufficient for visibility, and a preference for lighting that does not disrupt natural circadian rhythms in both humans and wildlife. The council has opted for a color temperature of 5,000 Kelvin for outdoor lights, which is bright enough for safety while still being mindful of its impact on the environment.

Adaptive controls are also a crucial aspect of the ordinance, allowing for the dimming of lights during late-night hours when they are not needed. This feature is expected to conserve electricity and further reduce light pollution, aligning with the city's commitment to sustainability.

The discussions surrounding the ordinance highlighted the importance of addressing both residential and commercial lighting. While fixtures producing less than 1,000 lumens are exempt from regulation, the council emphasized the need for oversight on brighter residential lights to prevent disturbances between neighbors. The ordinance aims to provide a framework for managing light pollution while allowing residents to maintain adequate security lighting.

The council's decision reflects a proactive approach to urban planning, recognizing the growing concerns about light pollution as Brigham City continues to develop. With the Bear River Migratory Bird Refuge nearby, preserving the dark sky is not only a matter of community aesthetics but also vital for protecting local wildlife habitats.

As Brigham City moves forward with implementing this ordinance, residents can expect a more harmonious balance between safety, security, and environmental stewardship in their community.
