Heritage oaks may be removed only with a Planning Division permit AND enhanced mitigation: planting five 5-gallon native oaks for each heritage tree removed, OR paying an in-lieu fee per tree into the City's Oak Tree Preservation Fund.

Rocklin FAQ
How do I measure DBH to know if my oak is a heritage tree?
Use a diameter tape (or wrap a flexible measuring tape and divide circumference by Pi) at 4.5 feet straight up from the root crown. If the trunk forks below 4.5 ft, measure just below the fork. Any oak 24 inches or larger is a heritage tree under Ch. 17.77.
Can I pay a fee instead of planting five replacement oaks?
Yes. The ordinance allows property owners to pay an in-lieu fee per tree into the Rocklin Oak Tree Preservation Fund instead of planting. The current fee schedule is set by City Council resolution; contact Planning for the current rate.
Does the heritage tree rule apply to dead oaks?
If the oak is genuinely dead or dying (certified by an arborist report), the City may waive mitigation, including for heritage-sized trees. Submit the arborist report with the Oak Tree Removal Permit application.
Roseville 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.
