Outdoor Lighting Regulations

The Cottonwood Heights City Council has requested the preparation of outdoor lighting regulations. (Bolded wording below contains links to additional information on the topic). 

Adequate nighttime lighting is important to allow human activity to safely continue after the sun goes down, but inappropriate lighting practices can result in:
•     light pollution 
•     light trespass 
•     glare 
•     poor lighting color increasing glare and affecting human health 
•     poor energy conservation 
•     impact on wildlife and natural ecosystems, and
•     creating skyglow.

These issues can reduce full enjoyment of private property rights, impair human health and safety, waste energy, and create a poor nighttime ambiance. This ordinance provides regulations that seek to mitigate the above noted issues.
