Costa Mesa FAQ
What qualifies as a heritage tree in Costa Mesa?
Heritage trees are generally defined by species, trunk diameter, age, or historical significance. California sycamores, coast live oaks, Torrey pines, and other mature specimens above a threshold trunk diameter may qualify. Contact the Planning Division at (714) 754-5245 for a determination on a specific tree.
Can I remove a heritage tree on my property?
Only with prior Planning Division approval. You must submit a California licensed arborist report demonstrating that the tree is dead, diseased beyond treatment, or cannot be preserved given reasonable use of your property. Approved removals typically require enhanced replacement at two or more trees per heritage tree.
What protection is required for heritage trees during construction?
Tree protection fencing must be installed at the drip line before construction begins. No grading, soil compaction, material storage, or root disturbance is permitted within the protection zone. The arborist may specify additional measures such as root pruning supervision or irrigation during construction.
Garden Grove FAQ
Does Garden Grove have a heritage tree ordinance?
No. Garden Grove does not have a formal heritage tree ordinance or registry. Trees on public property are protected as city assets, and trees planted as conditions of development approval retain their protected status, but there is no special designation for old or large trees on private property.
Are oak trees protected in Garden Grove?
California oak woodland conservation laws primarily apply to rural and undeveloped areas. In urban Garden Grove, oak trees on private residential property are generally not subject to special removal restrictions unless they were planted as a development condition.
When should I avoid removing trees?
Avoid tree removal during bird nesting season (typically February through August) unless you confirm no active nests are present. Disturbing nesting birds violates the Migratory Bird Treaty Act regardless of whether the tree itself is protected.
