Cal. Pub. Res. Code § 25339

After the commission designates a transmission corridor zone, it shall identify that transmission corridor zone in its subsequent strategic plans adopted pursuant to Section 25324. The commission shall regularly review and revise its designated transmission corridor zones as necessary, but not less than once every 10 years. In revising designations of transmission corridor zones, the commission shall follow the procedures of this chapter. If, upon regular review or at any other time, the commission finds that a transmission corridor zone is no longer needed, the commission shall revise or repeal the designation and, as soon as practicable, notify the affected cities, counties, state and federal agencies, and property owners within, or adjacent to, the transmission corridor zone.
