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.
(a) Lighting Zones. Exterior lighting allowances in California vary by Lighting Zones (LZ).
(b) Lighting Zone Characteristics. TABLE 10-114-A specifies the relative ambient illumination level and the statewide default location for each lighting zone.
(c) 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.
