Local Outdoor Lighting Ordinances

Local Outdoor Lighting Ordinances

Below are links to the outdoor lighting ordinances of some nearby cities in the Hill Country. They all differ from each other in one aspect or another and some are pretty detailed.

But it doesn't have to be complicated. Controlling light pollution isn't rocket science. It's mostly just common sense.

A friend, who was in charge of planning a new parking lot for a church in Blanco, asked us “What kind of lights do I need to buy to be in compliance with the new ordinance?” The answer was simple, and he didn't even have to read the ordinance to “get it.” We told him that he could install any kind of outdoor lighting he wanted to as long as it (1) had a color of 3,000 Kelvin or preferably less and (2) did not shine off the property. That's really all there is to it!

KELVIN TEMPERATURE. There are all kinds of reasons to have low-Kelvin-temperature lighting, the kind that has a warm, orangish glow instead of that piercing bluish light that causes glare, inhibits the body's production of melatonin, and contributes to diabetes, cancer, and other maladies. There's detailed information on this website about all that.

LIGHT TRESSPASS. Keeping one's light on one's own property is just common courtesy. If the light doesn't shine off the property, it's not going to irritate a neighbor and it's not going to shine above the horizontal plane to pollute the night sky. It's just common sense.
