National Park Service Cooperative Agreement: IDA signed a cooperative agreement with the National Park Service (NPS) in December 2010 to upgrade lighting in nine national parks. Innovative lighting designs will be installed in 2012 that will protect wildlife and nocturnal habitats while providing safety and security to evening visitors. Under the terms of the agreement, IDA will conduct lighting analyses and develop lighting plans for each park; order dark sky friendly lighting fixtures; and assist with the installation of the lighting. The nine parks participating in the project are: Canyon De Chelly (Arizona); Chiricahua (Arizona); Homestead (Nebraska); Mojave (California); Redwood (California); Cedar Breaks (Utah); Craters of the Moon (Idaho); Morristown Historical Park (New Jersey); and Tallgrass Prairie (Kansas).
IDA will also develop best practice outdoor lighting design standards for parks and natural environments.
The work will be completed in 2013.
The Fred Maytag Family Foundation. In January 2012, the Fred Maytag Family Foundation awarded a $25,000 grant to IDA for its Dark Sky Parks and Protected Areas Program (DSPPA). This program will expand the work that IDA began under the National Park Service Cooperative Agreement to other national and state parks that would like to upgrade their lighting but don’t have funds to do so. The program will also work with parks, both in the US and around the world, that are interested in applying for anInternational Dark Sky Places (IDSP) designation.
