Read the Values Centered Outdoor Lighting Resolution adopted by IDA in January 2021

Download Board Policy  

The new policy stresses that the interplay of all five responsible light principles must be considered in the design, installation and use of outdoor lighting, and that treating the principles in isolation from one another is insufficient to address the growing global problem of light pollution.

Is your home nature, neighbor, and night sky friendly?

The International Dark-Sky Association has developed a program called the The "Dark Sky Friendly Home Lighting Program" where you can certify your home to be dark sky friendly. 

The "Dark Sky Friendly Home Lighting Program" can be completed in four easy steps:

  1. Based on five lighting principles outlined by IDA (see below), evaluate each outdoor light on your property and complete the evaluation portion using a downloadable Home Lighting Inventory Form.
  2. Follow the recommendations given for each step and take action to improve any of your fixtures .
  3. Confirm that your fixtures are dark sky friendly by recording the date that you took any necessary action.
  4. Submit your results via our self-certification form. Then download and display a free Dark Sky Friendly Home certificate!
