Glendale (CA) city officials are forcing residents to take down mirrors they’ve attached to trees in the public right-of-way so they can better see oncoming traffic while exiting their driveways. Residents say in the absence of any speed-reduction enhancements, such as speed humps, the round convex mirrors are one of the few safety measures they have. City officials, though, say it’s about more than tree damage. City codes don’t allow anything to be attached to city-owned trees or street-light poles. Also, nothing can be placed in the public right-of-way because of liability concerns.
