Los Angeles FAQ
Can I cut a big oak on my own LA property?
No. If the oak is a native Quercus species with a trunk 4 feet around or larger, you need a Board of Public Works permit and arborist report before any removal or major pruning.
What counts as a heritage tree in LA?
LA uses "protected tree" rather than heritage. The four protected natives (oak, sycamore, walnut, bay) at 4-foot circumference qualify. Non-native species are not protected at the city level.
What if I damage roots during construction?
Encroachment into the 5-foot protected zone around the dripline – including grading, trenching, or hardscape – triggers permit review and may require monitoring by a certified arborist.
Torrance FAQ
How is a heritage tree designated?
Based on trunk size (typically 24+ inches), species rarity, age, or historical significance. Residents may nominate trees.
Can I ever remove a heritage tree?
Only with special approval, typically from city council or tree commission. Granted mainly for safety hazards.
