Thornton designates heritage or landmark trees based on size, age, or species. Removal or damage to heritage trees carries significant penalties.
Thornton may designate certain trees as heritage, landmark, or specimen trees based on criteria including trunk diameter (typically 24+ inches), species rarity, historical significance, or ecological value. Heritage trees receive enhanced protection beyond standard tree ordinances. Removal requires special council or commission approval and is rarely granted except for safety. Construction projects must protect heritage trees with root zone barriers. Damage during construction triggers fines and remediation. Residents can nominate trees for heritage status.
Unauthorized removal of heritage tree: $2,000 to $25,000. Damage during construction: $1,000 to $10,000 plus remediation costs.
