Summary
Alameda automatically protects three specific tree categories citywide: the palm trees on Burbank Street and Portola Avenue, any street tree on Thompson and Central Avenues, and any Coastal Live Oak ten inches or more in diameter, and none can be removed without a Historical Advisory Board certificate of approval.
No protected tree shall be removed without the approval of a certificate of approval from the Historical Advisory Board. Protected trees shall include: the palm trees in the public right of way on Burbank Street and Portola Avenue; any street tree on Thompson and Central Avenues; and any Coastal Live Oak (quercus agrifolia) with a ten (10″) inch or greater diameter measured four and one-half (4.5') feet above the ground. Applicants shall submit an arborist's report in a case where the health of the tree is the reason for the requested removal of the tree, or a contractor's report in a case where damage to foundation or other structures is the reason for the requested removal of the tree. Any street tree shall be replaced, at the applicant's expense, to the satisfaction of the Public Works Director. Any oak tree shall be replaced with a minimum of two (2) oak trees of ten (10) gallon size or larger to the satisfaction of the Planning and Building Director.

Full Breakdown
7(c) of the Municipal Code creates a categorical "protected tree" list separate from the case-by-case Historical Monument designation process covered elsewhere in the same chapter. No protected tree may be removed without a certificate of approval from the Historical Advisory Board, and the list is fixed by name and location rather than by an individual designation hearing: the palm trees in the public right of way on Burbank Street and Portola Avenue, any street tree on Thompson and Central Avenues, and any Coastal Live Oak (Quercus agrifolia) measuring ten inches or more in diameter at four and one-half feet above the ground.
An owner seeking removal for the tree's health must submit an arborist's report; an owner citing damage to a foundation or other structure must submit a contractor's report instead. Replacement is mandatory: any protected street tree removed must be replaced at the applicant's expense to the Public Works Director's satisfaction, while any removed oak must be replaced with at least two oak trees of ten-gallon size or larger to the Planning and Building Director's satisfaction. A denial or approval can be appealed to the City Council within ten days, and the Council can only reverse the Board's decision on evidence that the tree is incapable of earning an economic return on its value.
Certificates of approval are valid for three years, and notice of the hearing goes by postal card or letter to owners of record within 300 feet of the tree. This list sits within Article VII, Historical Preservation (Section 13-21), which the City administers through the Historical Advisory Board and the Planning and Building Department.
Violations & Fines
Removing a listed protected tree without a Historical Advisory Board certificate of approval is a violation of the Municipal Code under Section 13-21.10. Because these trees typically stand within a designated area or affect a contributing resource, an unapproved removal can trigger the same five-year stay on new building or construction permits for the site that applies to unauthorized demolition of a Historical Monument, along with a required replacement or restoration plan submitted to the Planning and Building Director.
