DLC Compiles Outdoor Lighting Ordinances Across The US & Canada

Image: designlights.org

The DLC compiled a list and interactive maps of locations with published outdoor lighting ordinances to mitigate light pollution. These maps show states, provinces, and cities/towns, throughout Canada and the U.S., with outdoor lighting ordinances. States and provinces shaded blue have a statewide/provincewide policy. The round markers indicate cities, towns, and counties with an ordinance. For further detail on individual policies, please inquire directly with the municipality.

The DLC interactive maps are located here.
