Good News!

We have an important update regarding the American Elm tree in Sonoma Plaza.

Following a comprehensive assessment following the tree’s diagnosis of Oak Root Fungus (Armillaria mellea), which included both basic and advanced evaluations, it has been determined that the American Elm poses no imminent danger. As a result, we will be removing the barricades around the tree.

The assessment revealed that the tree has an overall low risk of trunk or root collar failure within the next three years. The likelihood of failure for the trunk, root collar, or buttress roots is considered improbable over this period. This positive outcome ensures that the tree does not currently pose a threat to public safety.

City staff will be working closely with a professional arborist to implement ongoing monitoring and maintenance to protect the health and safety of the tree.

Thank you for your patience and understanding. Enjoy the beautiful Sonoma Plaza!
