What is a Parkway Tree?
A parkway tree is a tree that is typically planted by Public Works or a developer who built the home or building, adjacent to the edge of roadway within the County’s right of way. Los Angeles County cares for and maintains over 170,000 parkway trees located throughout the County’s unincorporated area along more than 3,200 miles of roadways.

Tree Planting Request Form
Public Works encourages resident participation in the expansion and renewal of our urban forest. In order to ensure the proper species selection, planting and sustainability of the new tree, we require that all planting be coordinated with the appropriate Road Maintenance District Urban Forestry Unit.
Road Encroachment Permit
With a permit from Public Works, you can also plant a tree in the parkway if you are the owner of the property adjacent to the parkway. Please apply for a Road Encroachment Permit to plant a tree.
