Tree Preservation

Tree preservation, policy, and resources

One of the City of San Gabriel's priorities is the preservation and ongoing maintenance of our mature trees.  To help oversee this priority, the City Council adopted the Tree Protection and Preservation Regulations for single-family, multi-family, commercial and industrial zones. This code identifies which trees are subject to the ordinance and when a permit for removal or trimming is required. While regulations play an important role in preserving mature trees for the future, many trees are lost due to improper maintenance.
