5. Overview of Lighting Regulations Table 7. Lighting Zones and Uses Zone Recommended Use or Areas Zoning Considerations LZ‐0 Lighting Zone 0 should be applied to areas in which permanent lighting is not expected and when used, is limited in the amount of lighting and the period of operation. LZ‐0 typically includes undeveloped areas of open space, wilderness parks and preserves, areas near astronomical observatories, or any other area where the protection of a dark environment is critical. Special review should be required for any permanent lighting in this zone. Some rural communities may choose to adopt LZ‐0 for residential areas. Recommended default zone for wilderness areas, parks and preserves, and undeveloped rural areas. Lighting Zone 1 pertains to areas that desire low ambient lighting levels. These typically include single and two family residential communities, rural town centers, business parks, and other commercial or industrial/storage areas typically with limited nighttime activity. May also include the developed areas in parks and other natural settings. Recommended default zone for rural and low density residential areas. Lighting Zone 2 pertains to areas with moderate ambient lighting levels. These typically include multifamily residential uses, institutional residential uses, schools, churches, hospitals, hotels/motels, commercial and/or businesses areas with evening activities embedded in predominately residential areas, neighborhood serving recreational and playing fields and/or mixed‐use development with a predominance of residential uses. Can be used to accommodate a district of outdoor sales or industry in an area otherwise zoned LZ‐1. Recommended default zone for light commercial business districts and high density or mixed use residential districts. Lighting Zone 3 pertains to areas with moderately high lighting levels. These typically include commercial corridors, high intensity suburban commercial areas, town centers, mixed use areas, industrial uses and shipping and rail yards with high night time activity, high use recreational and playing fields, regional shopping malls, car dealerships, gas stations, and other nighttime active exterior retail areas. Recommended default zone for large cities' business district. Lighting zone 4 pertains to areas of very high ambient lighting levels. LZ‐4 should only be used for special cases and is not appropriate for most cities. LZ‐4 may be used for extremely unusual installations such as high‐density entertainment districts, and heavy industrial uses. Not a default zone.
