Authority for Caltrans to control encroachments within the State highway is contained in the Streets and Highways Code starting with Section 660.
Caltrans has adopted AASHTO’s October 2005 publications, "Policy on the Accommodation of Utilities Within Freeway Rights-of-Way," and "A Guide for Accommodating Utilities Within Highway Rights-of-Way."
Caltrans’ general policy is to allow utility facilities within conventional rights of way subject to reasonable conditions to provide for the safety of the traveling public and to permit the improvement of the highway.
Caltrans’ policy with regard to freeways and expressways is to exclude utility facilities from within access controlled rights of way, to the extent practicable. It recognizes that freeway rights of way are a valuable commodity, and that such value to the traveling public could be seriously eroded by allowing uncontrolled access by utility facilities. The policy is intended to provide a safe environment for traffic operations, minimize the disruption to the traveling public, and assure the safety of utility employees during maintenance of their facilities.
