International Dark Sky Communities

An IDA International Dark Sky Community is a town, city, municipality or other legally organized community that has shown exceptional dedication to the preservation of the night sky through the implementation and enforcement of a quality outdoor lighting ordinance, dark sky education and citizen support of dark skies. Dark Sky Communities excel in their efforts to promote responsible lighting and dark sky stewardship, and set good examples for surrounding communities.

Submission and Review Process

Dark Sky Place applications are reviewed on a rolling basis and in the order they are received. When the applicant completes a draft application, they will need to email a single PDF document to the Director of Conservation with the name of the site and certification category in the subject line. Staff will reach out to the applicant with further instructions and guidance to craft a complete and thorough application. Once IDA Staff deems the application complete, it will be provided with a batch of other completed nominations to the Dark Sky Places Committee (DSPC) for consideration.
