Let’s not "trash" our night skies!
Light trespass occurs when stray light shines onto your neighbor’s land. Light trespass infringes on the property rights of the neighbor who has unwanted light intruding onto his or her property. It can lower property values, reduce the quality of the nighttime environment and be a general irritant. Citizens should have the right to the full enjoyment of their property without being forced to live with unwanted light directed onto their property. To eliminate light trespass, shield and aim all lights so the illumination stays within your own property lines. Also, if your neighbors can see the source of your light from their property (this means they can see the light bulb) then your light is committing light trespass. The worst offender of this type of light trespass is unshielded yard lights. Remember that your property rights stop at your property line. Unless your lights stop there too, they are creating light trespass onto the neighboring property. The upside to shielding and directing lights is you can use less wattage to get the same amount of light. This saves money and reduces the carbon footprint.
Work with your neighbors and the City of Blanco to keep light on the ground and within your property lines. Be a Good Neighbor.
