Question 1

Who can plant a tree on the sidewalk?

Accepted Answer

Planting a tree on the sidewalk requires a permit from Public Works. Residents or community organizations can plant a tree as long as they obtain a permit and plant a tree species approved by the Bureau of Urban Forestry.

Question 2

I got a flyer/postcard informing me that you are planting a tree near me. Where can I learn more about it?

Accepted Answer

If you’ve recently gotten a flyer or postcard from us or seen us on your block, please visit this Block Planting FAQ to learn more about our work and what to expect in the coming weeks.

Question 3

Do residents have to give their permission for the City to grant the permit to plant a tree on the sidewalk?

Accepted Answer

No. Public Works give permits for planting trees on the sidewalk, and the City intends to plant trees in all viable sites in order to meet climate-resilient goals.

In 2016, the city’s voters decided with Prop E that the City will manage all street trees, moving the ownership of street trees from the homeowner to the City.

Question 4

Who is going to take care of this tree?

Accepted Answer

We will plant the tree for free and prune it for the first three years; Public Works will water once a week during that time. You can even come out for one of our Tree Care events to learn more and help out!

After the first three years, the city is legally obliged to care for your tree, including pruning it every 3-5 years.

Question 5

I’m concerned that trash and dog poop will end up in my tree basin.

Accepted Answer

Generally, tree basins that are cared for don’t attract trash. When we plant the tree, we cover it in a 3” layer of mulch which looks nice and keeps the soil moist. After the first year you may plant small non-aggressive annuals such as strawberry, small succulents, and native flowers.

Question 6

I’m worried that the tree could crack my sidewalk and I will have to pay.

Accepted Answer

We try to minimize sidewalk damage by planting trees that do not have aggressive root systems. We also water trees regularly in the first three years to encourage roots to grow downward.
In 2016 San Francisco residents voted for Street Tree SF, which shifted responsibility for the care and repair of street trees from property owners to the city. The city is now responsible for sidewalk damage caused by street trees. You will not have to pay or be held liable.

Question 7

I rent my house and would need my landlord’s permission.

Accepted Answer

Since the sidewalk is city property and the city has given us permission, we don’t need your landlord’s permission to plant a tree. If you would like a tree, we can plant one or you can have your landlord call us for more information about getting a tree.

Question 8

What kinds of trees do you plant?

Accepted Answer

Tree species selection is per site/project. Most neighborhoods will have a general list, and then narrow it down with the information specific planting site

Question 9

Will the tree roots grow into my underground utility lines?

Accepted Answer

We maintain a minimum distance from utility lines, which we have marked out and delineated so we know where they run. Tree roots grow where water is available - in cases where they interfere with utilities, it’s often initially caused by a leaking pipe, and the roots follow the water into the pipe.  Proper slow drip “deep watering” is provided to mitigate this risk to encourage the roots to follow the water down to the natural water table. Here’s how we make sure to avoid this issue:

Here’s how we make sure to avoid this issue:
Utility Check: We work with utility providers to identify the location of underground communication, electric, and gas utilities so we can avoid them.  There are no records for sewer line markings, but we always identify the sewer vent before approving a tree location.  Without locating the sewer, we do not plant trees.
Basin Placement: Trees are planted at least 3 feet away from communication, electric, and gas lines and at least 5 feet away from sewers. If a sewer vent cannot be located, a tree will not be planted unless the tree is a request and there is a vent perhaps hidden in the garage.
Deep root watering: Slow drip watering (from our water bags) allows water to penetrate slowly into the soil and encourages roots to grow deep rather than horizontally, increasing the potential of roots getting into the sewer.
Sewer lines: A tree may "find" the leak if the property has a leaking pipe. In most cases, roots will not grow into pipes unless there is an existing opening or water is emitted.
Soil Compaction: When trees are planted, they are done so where the soil is augered/loosened straight down. The soil compaction around the augered zone means roots are discouraged from growing into the area.

Question 10

What can I do if I do not want you to plant a tree?

Accepted Answer

If, after reading the FAQs, you still have concerns, please fill out this form.  The city intends to plant street trees in all possible sites in order to meet climate resilient goals. Completing the form may result in delaying the planting for a year or so.
