StreetTreeSF is a voter-approved initiative managed by San Francisco Public Works to professionally maintain and care for the 125,000-plus street trees growing throughout all neighborhoods in the City.
San Francisco Public Works is developing StreetTreeSF into an efficient and cost-effective system to routinely and proactively maintain street trees, ensuring that all public trees are inspected and pruned on a regular basis. StreetTreeSF will also repair sidewalks that have been damaged by street trees.

Now that StreetTreeSF is maintaining and caring for all street trees, residents do not need to prune trees themselves.
Pruning your tree could result in a fine of $2,000 or more, per tree*. StreetTreeSF is now your street tree care professional, so you can leave the pruning to us!

Street Tree Pruning
San Francisco’s urban forest is remarkably diverse. Our streets are lined with conifers, broadleaf evergreens and deciduous trees. Even within a single species, individual trees vary widely in age, size, health and structure.
Because every tree is different, so is its pruning needs. Some trees need little or no pruning, while others need significant work. A young tree may need pruning to build a strong structure, while a mature tree may need branches removed to manage pests or keep clear of overhead utility lines.
Routine pruning
Public Works prunes street trees on a regular cycle, visiting each tree about every five years. Routine pruning helps us:
- Strengthen tree structure and reduce the risk of branches or trees failing, including removing dead branches
- Prevent or manage pests
- Keep trees healthy and attractive
- Maintain clearance for people walking, vehicles, and buildings
- Improve safety and security on our streets
- Repair damage caused by wind
- Lower long-term maintenance costs by shaping young trees early
- Support flowering and fruiting in certain species
Pruning by request
Between routine visits, we also respond to reports of street tree problems, including:
- Broken or hanging branches
- Damaged or dead branches
- Branches blocking streets, sidewalks, or bike lanes
- Branches blocking traffic signs or signals
To report a problem with a street tree, contact 311.
Tree Pruning Schedule
Since 2017, Public Works has been responsible for maintaining San Francisco’s street trees under Proposition E. Our first citywide pruning cycle, StreetTreeSF 1.0, taught us valuable lessons.
We’re now launching StreetTreeSF 2.0, with a focus on working more efficiently. In October, 2026, Public Works contracted with urban tree intelligence company greehill to catalog all of San Francisco’s 100,000-plus street trees using LiDAR, a first for the City. As opposed to a years-long endeavor, with LiDAR, the expectation is to have a full count of the trees in San Francisco’s urban forest in about a month. Public Works will use the data collected to refine our pruning schedule. The data collected from the LiDAR-assisted tree inventory will help better inform decisions about what the schedule, budget and planning should look like going forward. With more than 70 standardized data points per tree, the data collected on San Francisco’s urban forest is expected to be the most extensive and comprehensive to date.
The pruning map has been integrated into the new San Francisco Street Tree Map.

Why is the pruning map organized by blocks and not by street or by tree?
San Francisco’s tree maintenance schedule is organized by city blocks to allow for all work needed on a block to happen at the same time. This is the most efficient and cost-effective method to maintenance and ensures that there are minimal interruptions to the neighborhood.
How is the scheduling of blocks being prioritized?
The scheduling of blocks is based on the concentration of tree prunes, tree removals and sidewalk repairs that are a high priority. If a block has trees and sidewalk repairs in deteriorating condition that pose a safety risk and are located near bus stops, schools and senior centers, work on these blocks will be scheduled for maintenance as soon as possible.
Why is my area scheduled after another area with fewer trees?
The area scheduled before your area may have fewer overall trees, but a higher number of high-risk trees in deteriorating condition, giving that area priority.
There is a dangerous looking tree in my area but the estimated pruning isn't scheduled for a couple of years. Is this an issue?
A tree that looks dangerous may not pose an immediate safety risk now and therefore has been scheduled for pruning at a later time. However, the tree’s condition is being tracked by an inspector and recorded in a database. Information in the database about the tree over time will inform any changes to the pruning schedule for that tree. While we are moving toward a preventative maintenance pruning schedule for all trees, we are still inspecting and noting the condition of trees at risk and we will still address trees which pose an immediate risk to public safety.
I am a property owner and I want to continue to maintain my street tree. Can I do so?
Yes, you can opt out of StreetTreeSF if you are a property owner who would like to continue to maintain their street tree(s).
Your commitment to maintain your tree includes caring for it per City standards. Once initiated, the opt-out process will connect you with one of our certified tree inspectors for an inspection of your tree. The process concludes with the signing of the Street Tree Maintenance Agreement. Contact us at urbanforestry@sfdpw.org or 628-652-TREE (8733) to begin the opt-out process.
Where can I get more information or direct a question?
For more information about street trees in general, contact San Francisco Public Works Bureau of Urban Forestry at 628-652-TREE (8733) or urbanforestry@sfdpw.org.

If a street tree near you is posing an immediate safety concern in a public right-of-way, report the issue to 311 online, via the mobile SF 311 app or call 311. Before you contact us, determine the street address and the nearest cross-street where the street tree is located.
Note: Urgent pruning requests must meet an immediate safety concern requirement in order to be addressed. Conditions requiring immediate attention include:
- Broken, hanging limbs
- Damaged and/or dead limbs
- Blocked streets, sidewalk or bike lanes (clearance issues)
- Interference with traffic signs or signals
Pruning requests for trees overgrown and blocking windows, brushing up against buildings or other issues that do not pose a threat to safety in a public right-of-way will be serviced during StreetTreeSF's regular maintenance cycles.
