NEW Protected Trees Ordinance ( S.M.M.C. 13.40 ) - Effective 7/1/21
The “Protected Trees” Ordinance (S.M.M.C 13.40) was adopted by San Mateo City Council on May 3, 2021. This new ordinance, effective July 1, 2021, replaces the prior “Street Trees” Ordinance (13.35) and “Heritage Trees” Ordinance (13.52).
Definition of Heritage Tree - A tree will now be classified as a Heritage Tree if it is:
Any oak (Quercus spp.) with a trunk diameter of ten (10) inches or greater
Any other species with a trunk diameter of fifteen (15) inches or greater
Location of trunk diameter measurement - Trunk diameter will now be recorded at the industry standard height of 54” above grade.
Administrative Guidelines - A companion document to the Ordinance will be released on July 1, 2021. The Administrative Guidelines will assist the public in interpreting and complying with the City’s tree regulations. The Administrative Guidelines will include visual aids, a replacement species list, and a matrix of required replant ratios and monetary equivalencies.
More flexible replant options - Under the new Protected Trees Ordinance, Heritage Trees may be replaced with a 15-gallon tree of "Preferred" species. "Preferred" species will be selected based on their mature size and a list will be included in the Administrative Guidelines released on July 1, 2021.
