As outlined in the City of Los Altos Tree Protection Ordinance (LAMC Chapter 11.08 ), all trees, regardless of species, that are 48-inches or larger in circumference (approx. 15-inches in diameter) are protected and require a Tree Removal Permit before they can be removed. The purpose of the Tree Protection Ordinance is to preserve and maintain the City’s urban forest and rural character by retaining and/or replacing large mature trees when possible and where appropriate.
