Simi Valley designates certain exceptional trees as heritage trees based on their size, species, historical significance, or ecological value. Heritage trees receive enhanced protection beyond standard tree preservation requirements.
Heritage trees in Simi Valley are designated by the city based on criteria including exceptional size (typically over 24-inch trunk diameter), historical significance, unique species, or prominent location. Native oaks are the most commonly designated heritage trees. Heritage trees may not be removed, significantly pruned, or have their root zones disturbed without specific approval from the Community Development Department. Construction projects near heritage trees must provide a tree protection plan prepared by a certified arborist, including root zone fencing, no-dig zones, and monitoring during construction. The root protection zone typically extends to the tree's drip line plus 5 feet. Damage to a heritage tree during construction is treated as a separate violation from any project permits.
Damaging or removing a heritage tree carries enhanced penalties of $5,000 to $25,000 per tree. Construction activity that damages a heritage tree may result in project stop-work orders. Violators must pay for full restoration including arborist treatment and extended monitoring. Criminal charges may be filed for intentional destruction.
