Caltrans is identifying and marking dead and dying hazardous trees that could impact the safety of the traveling public along the state highway. Some of these trees could fall toward the roadway from your property, blocking traffic or causing injury and damage.

Marked trees along highways in your neighborhood may be on federal, state, county or private property. Written permission must be provided by all affected property owners before Caltrans can perform its work. There is no cost to you for hazardous tree removal.

The Hazardous Tree Assesment & Removal Process includes a "Permission to Enter" form. If you receive a "Permission to Enter" form in the mail, please sign and return or submit it electronically by the deadline indicated on the form.
