I propose the development or adoption of a lighting ordinance based on the Model Ordinance drafted by the Dark Sky Association and approved by the Illumination Engineers Society of North America which help guide the reduction of light pollution. See: http://darksky.org/lighting/lighting-ordinances/ and a PDF of the model ordienance with explanations is available at: http://darksky.org/wp-content/uploads/bsk-pdf-manager/16_MLO_FINAL_JUNE2011.PDF
Unshielded and improperly install lighting reduces our ability to see all but the brightest stars at night, it creates unsafe interactions between drivers, pedestrians, and cyclists, decreases security through reduced visibility through correct lighting, and reduces the disruption of biorhythms impact of artificial light on humans and the environment. We can lead the area in properly installed and shielded lights and with other communities adopting these we will all see more of the night sky and be safer when out at night.
Attached is the model ordinance and I encourage everyone to read more about light intrusion and light pollution at http://darksky.org/lighting.
