Light Pollution

LIGHT POLLUTION CODE

The Cochise County Light Pollution code was adopted in 1983, with a major update in 2005.  The purpose of the Light Pollution Code is to preserve the dark night sky for astronomers and for the general public, while achieving safe, efficient lighting practices.

Some features of the Cochise County Light Pollution Code are:

  • Light trespass and off-site glare are not allowed
  • All lights must be fully shielded except:
  • Low voltage or solar landscape lighting rated at 10 watts or less
  • A limited number of lights with less than 1,000 lumen output (such as a 60 watt incandescent or quartz halogen or a 13 watt compact fluorescent fixture)
  • One flagpole light (2,000 lumens or less)
  • HOWEVER, all lights within 25 feet of a residential property must be fully shielded
  • Lumen caps are established by zoning and use
  • Floodlights (incandescent or PAR not exceeding 2,000 lumens) are exempt from lumen caps provided they are aimed no more than 45 degrees (halfway between straight down and straight to the side) and are controlled by a motion sensor devise, not to remain on over 10 minutes.
  • Lighted Outdoor Recreation Facilities and Waivers from the Light Pollution Code standards require a Special Use Permit.
  • Temporary exemptions for emergencies exceeding 48 hours require Planning Department approval.
