Tree Preservation

Tree preservation, policy, and resources

As of July 1, 2023, the fee for a Tree Trimming and/or Tree Removal Application is $268 per application.

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.

Pursuant to City Code Section 95.02, the Community Development Director's designee for Tree Preservation matters and tree actions is John Gonzales, City Arborist.
