10-114 Determination of Outdoor Lighting Zones and Administrative Rules for Use

This section establishes rules for implementing outdoor lighting zones to show compliance with Section 140.7 of Title 24, California Code of Regulations, Part 6.

1. Lighting zones. Exterior lighting allowances in California vary by Lighting Zones (LZ).
2. Lighting zone characteristics. Table 10-114-A specifies the relative ambient illumination level and the statewide default location for each lighting zone.
3. Amending the lighting zone designation. A local jurisdiction may officially adopt changes to the lighting zone designation of an area by following a public process that allows for formal public notification, review and comment about the proposed change.

4. Commission notification, amended outdoor lighting zone designation. Local jurisdictions who adopt changes to the State Default Lighting Zones shall notify the Commission by providing the following materials to the Executive Director:

   1. A detailed specification of the boundaries of the adopted lighting zones, consisting of the county name, the city name if any, the zip code(s) of the redesignated areas, and a description of the physical boundaries within each zip code;
   2. A description of the public process that was conducted in adopting the lighting zone changes; and
   3. An explanation of how the adopted lighting zone changes are consistent with the specifications of Section 10-114.
