The night view of previous generations has virtually disappeared for city dwellers today. Urban children gaze upon the Milky Way in planetariums.

Unfortunately, population growth and urban sprawl now threaten the skies of rural America with the same fate — even areas around remote astronomy observatories. While zoning is a round-the-clock protector, land-use activity tends to be overlooked more easily at night.

This issue of Zoning Practice acknowledges the importance of exterior lighting, defines different types of light pollution, and discusses the provisions necessary to carry out a community's lighting objectives. It concludes with a model lighting ordinance.
