Verified from official government sources
The Tri-Cities regulate outdoor lighting to cut glare and sky glow across the arid Columbia Basin. Richland and Kennewick require new exterior fixtures to be fully shielded and aimed downward, protecting the desert night sky.
Richland Municipal Code Ch. 23.58
It is intended to reduce or eliminate problems of glare, minimize light trespass into public spaces and private property, promote energy conservation, protect the nighttime character of the desert sky, and help reduce the energy and financial costs of outdoor lighting.
Tri-Cities zoning codes prohibit outdoor lighting from spilling past property lines. Kennewick defines light trespass as light shining beyond the property boundary and requires fixtures aimed so the lamp's line of sight stays on the owner's lot.
Kennewick Municipal Code Ch. 18.39
Light Trespass means the shining of light produced by a luminaire beyond the boundaries of the property on which it is located.
