1. Caltrans contractors knock on doors to seek verbal permission to assess hazardous trees on private property. Door hanger notice left on property.

2. Dead or dying trees marked with orange paint.

Check your mailbox for a "Permission to Enter" form (about 1-6 months after trees are marked).

3. Sign and return the "Permission to Enter" form by the indicated deadline.

No cost to property owner and trees cannot be removed without permission.

4. If the form is not returned, or permission is denied, the property owner is liable for future damage that may occur if the tree falls on the highway.

5. Once permission is received, a Caltrans Right of Way Agent will execute an agreement to enter the property and remove the dead trees.
