services for City facilities.
Tree trimming is conducted throughout the year. Each City tree is trimmed approximately once every three to four years. Click here

Tree Maintenance FAQ's
Am I allowed to trim the City tree in front of my property?
Trees owned by the City may not to be trimmed by anyone other than City staff unless a permit is obtained first. To obtain a permit to have your City tree trimmed by a qualified and insured arborist, contact the Tree Maintenance Division at (310) 253-6420.
The City is not responsible for maintaining trees located on private property. Trees located on private property whose branches interfere with electrical transmission lines or whose roots interfere with water metering devices may be altered by Southern California Edison or the Los Angeles Department of Water and Power or the Golden State Water Company to remove that portion of the tree that is creating the obstacle.
Is it okay to place ground cover, mulch or plants over tree roots?
Mulching or planting within the drip line of any shallow rooted tree should be done with care. Suffocation may result if roots are unnaturally buried. Mulching should be done lightly and kept from coming in contact with the bark. Any ground cover planted around tree roots should be drought tolerant. Trees growing within a lawn area will be forced to grow shallow roots because of the way they are watered.
What can I plant in the parkway? Who is responsible for maintaining it?
A parkway is the land area between the street curb and the sidewalk. While parkways are not intended for pedestrian passage, it is important that they allow vehicle passengers to safely and easily open their car doors and reach a nearby sidewalk. It is also critical that they not obstruct the visibility of traffic, traffic signals, and traffic signs or otherwise cause hazards. A permit is required for planting in the parkway.
It is the adjacent property owner, not the City, who is required to maintain all plantings and other items in the parkway. The property owner is also responsible for ensuring that the parkway is kept in a clean and neat condition and free from objectionable matter and from encroachments or obstacles which may pose a hazard to persons or property.
When is the best time of year to prune/trim trees?
Pruning may be done any time of the year, but some times of year are better than others. Deciduous trees that flower before the end of May should be pruned right after blooming. Deciduous trees that flower after May should be pruned between January and March. Prune flowering Cherry trees in late summer, flowering Evergreens in May, and Conifers in autumn. Remove dead, damaged, or diseased wood as soon as it is discovered.
How do I get a new tree planted on my street?
The City plants new trees every year, replacing dead or diseased trees and planting new ones in areas that do not currently have trees as the budget allows. To request a new tree planting, contact the Tree Maintenance Division at (310) 253-6420.
How do I care for the City trees along my property?
The City waters newly planted trees for the first year of their life. Afterwards, property owners are expected to water City trees. In the summer months, a single 30-gallon watering per week is recommended to seep below the surface level to reach the deeper roots. In the winter months, a single 15-gallon watering per week will be sufficient.
Exercise caution when using string trimmers near root and bark areas to avoid nicking them. Repeated wounding of the bark and roots by string trimmers may severely damage the trees health.
How tall will my tree grow?
Many of the City's nearly 16,000 trees are Ficus, Palm, Elm, Cedar and Pine. Ficus and Elm trees grow as high as 60' and Palm, Cedar and Pine trees grow to 100'. Click here for more information.
