10-114 Determination of Outdoor Lighting Zones and Administrative Rules for Use
- Lighting zones. Exterior lighting allowances in California vary by Lighting Zones (LZ).
- Lighting zone characteristics. Table 10-114-A specifies the relative ambient illumination level and the statewide default location for each lighting zone.
- 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. The local jurisdiction may determine areas where Lighting Zone 4 is applicable and may increase or decrease the lighting zones for areas that are in State Default Lighting Zones 1, 2 and 3, as specified in Table 10-114-A.
- 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;
- A description of the public process that was conducted in adopting the lighting zone changes; and
- An explanation of how the adopted lighting zone changes are consistent with the specifications of Section 10-114.
- The Commission shall have the authority to not allow Lighting Zone changes which the Commission finds to be inconsistent with the specifications of Section 10-114.
Authority: Sections 25402 and 25402.1, Public Resources Code.
