Becoming Dark Sky Community

A DSI Dark Sky Community is a town, city, municipality or other legally organized community that has shown exceptional dedication to preserving the night sky through implementing and enforcing a quality outdoor lighting ordinance, dark sky education, and citizenry support of dark skies.
