Palo Alto FAQ
Does California require permits to cut a backyard oak?
Not at the state level for individual residential trees. CEQA oak review applies to discretionary development projects, not routine private removals, though many cities require permits.
What counts as oak woodland under PRC 21083.4?
An oak stand with greater than 10% canopy cover that includes one or more native oak species, as defined by the statute.
San Jose FAQ
How do I know if my tree is "Ordinance-size"?
Measure the circumference at 24 inches above ground. A single-trunk tree at 56 inches around (about 18 inches DBH) or larger is protected. Multi-trunk trees are covered at 38 inches on any single stem.
What is a Heritage Tree?
A tree formally designated by City Council resolution for its size, age, or historical importance. The list is maintained by the Office of the City Arborist – removal is rarely approved.
Are fruit trees protected?
No. Fruit trees, eucalyptus, and a short list of nuisance species are exempt from the Ordinance-size protection, regardless of trunk size.
