Trees provide tremendous benefits to our city. They filter and clean the air, lower temperatures on hot days, and add to the scenic quality of our environment and the value of properties. Each tree is a symbol of our community's commitment to preserving the natural history of the region. Thousand Oaks is a Tree City, USA, having held the honor for nearly 20 years.

To protect this important resource, we have ordinances in place to guide their care, pruning and removal of certain oak and landmark trees. As a property owner, you are charged with the care and health of your protected trees.

What is a Tree's Protected Zone?

A tree's protected zone is five feet beyond the outer edge of canopy or 15 feet from trunk, whichever is greatest. Permits are required for any work impacting the tree or the soil in this area, other than removal of dead wood.
