Castro Valley FAQ
Do I need a permit to remove an oak tree in my Castro Valley yard?
No - private-property trees in standard Castro Valley are not subject to a removal permit. Coordinate with PG&E if the tree is near power lines and check your HOA CC&Rs.
Oakland FAQ
Can I trim my own oak tree?
Light maintenance pruning (under 25 percent of canopy) typically does not need a permit, but heavy pruning of a protected oak does; consult Tree Services or a certified arborist before cutting.
What about a hazardous tree?
Emergency removal of an imminently hazardous tree may proceed with same-day or after-the-fact notification to Tree Services; document the hazard with photos and arborist letter to avoid penalty.
