WHAT IS DARK SKY?
The Dark Sky denotes a place where the darkness of the night sky is reasonably free of interference from artificial light to reduce light pollution. Dark Sky lighting is lighting provided where it is needed, while reducing unnecessary scattered light and glare. Dark Sky focuses on only using as much light as is needed and when it is needed.
The advantages of reducing light pollution include an increased number of stars visible at night, reducing the effects of light on the environment, and cutting down on energy usage. Scientific studies have shown that light pollution, the inappropriate or excessive use of artificial light negatively impacts the environment, human health, military nighttime activities, and is wasting energy and financial resources. Thousands of cities across the world have adopted codes as a tool for a community to use to control light pollution, including glare, light trespass and skyglow.
To further the Military’s Mission, and as a part of the Dark Sky initiative, the Development Services Department, in consultation with the Office of Sustainability, developed an ordinance to modify and modernize the Military Lighting Overlay Districts. This ordinance also directed staff to initiate rezoning of properties within 5 miles of Lackland Air Force base to add the MLOD, and to rezoning the exiting MLOD-1 area within 5 miles of Camp Bullis. Additional information on these initiatives will be released at a later date. You can review the full ordinance here: MLOD Ordinance 2018-02-08-0079
