The City Arborist Program administers the City of Austin's Tree Ordinance and issues permits to remove or impact regulated trees. On private property, the City regulates three classifications of trees: 8- to 18-inch diameter, Protected Trees, and Heritage Trees. Tree preservation requirements are detailed in Section 3 of the Environmental Criteria Manual.
