There is a moment that happens a few dozen times a year in Provo, and it always plays out the same way. A homeowner gets a quote for taking down the big silver maple out front — the one dropping limbs on the driveway and buckling the sidewalk — books the crew, and comes home to a clean stump and a tidy yard. Two weeks later there is a letter from the city.
The tree was not theirs.
That surprises people, and it should, because nothing about the arrangement announces itself. You mow around the tree. You rake its leaves. Your sprinklers water it. Your address is the one the tree is in front of. Every intuition says it is your tree, and in Provo, if it stands in the planting strip between the sidewalk and the street, it is not.
Here is how the rules actually work, what they cost when you get them wrong, and how to hire a crew that will not walk you into an appraisal.
The line that decides everything
Utah Valley cities each have their own ordinance, and the details differ, but the organizing question is the same everywhere: where does the tree stand relative to the public right-of-way?
In Provo the answer is set out in Chapter 9.20 of the Provo City Code, titled Urban Forestry. The chapter runs from Section 9.20.010 through 9.20.180 and covers management authority, consent, conflicts with structures, tree preservation, injury, appraisal, hazardous conditions, enforcement and appeals. The version published on the city's code site is current through Ordinance 2026-17, passed June 9, 2026, and Section 9.20.050 itself carries an amendment history running to 2024.
The chapter divides the world into public trees and everything else. A public tree includes the trees growing in the planting strip — the band of ground between the sidewalk and the curb that most people call the park strip — as well as trees in parks and other city property. Those are the city's. A tree fully inside your property line, behind the sidewalk, is yours.
Section 9.20.050(2)(d) states the second half of that directly: a tree located behind a public sidewalk must be cared for and maintained by the property owner. The sidewalk, in other words, is doing more work as a boundary than most residents realize.
There is a wrinkle worth knowing. Not every Provo street has a formal parking strip. Where none has been established, Section 9.20.050(2)(c) makes the abutting owner responsible for maintaining all trees on the property up to the edge of the street or curb, and for all vegetation growing in that same area. So the absence of a strip does not mean the absence of a duty — it shifts it.
What you may not do to a public tree
Section 9.20.050(1) is the operative sentence, and it is written broadly on purpose. It is unlawful for any person or entity, other than a public entity operating on public property, to plant, remove, move, spray, trim, prune, cut above or below ground, disturb, or alter any public tree — or to cause any of those things to be done by others — without first obtaining the written consent of the City Forester.
Read that list again, because the common assumption is that only removal is regulated. It is not. Pruning is on the list. Spraying is on the list. So is cutting below ground, which is how a driveway-widening project or a trenching job for an irrigation line becomes a code question rather than a landscaping question. And the phrase or cause such acts to be done by others means hiring someone does not move the responsibility off you.
The single carve-out in that subsection is for line clearance tree trimming and maintenance performed by employees of the city's Department of Energy in coordination with the City Forester — which brings us to the part of this that trips up almost everyone.
Provo's tree department is inside the power company
In most cities, if you want to talk to somebody about a street tree, you call Parks. In Provo you are looking for the Forestry Division of Provo Power, the city's municipal electric utility.
This is not a filing quirk. The division's own description of its work puts the scale of it plainly: it manages tens of thousands of trees growing under electrical power lines and facilities, and separately prunes, removes, sprays and plants many thousands of street trees across the city. Provo has held Tree City USA certification for four decades, which requires an annual planting commitment and an active maintenance program.
Once you know the structure, the ordinance reads differently. The Department of Energy exemption in Section 9.20.050(1) is not an odd exception — it is the utility's line-clearance crews being allowed to do the job they exist to do, with coordination rather than a permit each time.
The practical takeaway: when you need to know whether a specific tree is public, call the forestry office with the address and ask. That single call is the cheapest step in this entire article.
The rule that catches people going the other way
Most of Chapter 9.20 restricts what you can do. Section 9.20.050(2)(a) does the opposite — it requires something of you.
An owner of private property abutting a Provo right-of-way is responsible for routine watering of the public trees in the adjacent planting strip, sufficient to maintain good health and vigor. And then the sentence that deserves to be read twice:
a property owner who does not water a public tree is liable for the death of such tree up to appraised value.
You do not own the tree. You may not prune it without written consent. And if it dies of thirst on your watch, you can be billed for it — at an appraised value determined by the same professional methodology the city uses when someone destroys a tree outright.
Subsection (2)(b) adds the companion duty: prevent damage to public trees from lawn mowers, weed trimmers, snow blowers and similar equipment. String trimmer damage around a young trunk is one of the most common and most avoidable ways a street tree dies, and the ordinance names the tool.
This combination — no authority over the tree, real responsibility for it — is unusual enough that it is worth planning around. If you are xeriscaping the strip and pulling out the lawn, the sprinkler zone that was incidentally watering the tree goes with it. Replace the water before you remove the grass.
What an appraisal actually means
The word appraised appears throughout Chapter 9.20, and it is not casual.
Section 9.20.050(1)(b) provides that where removal of a public tree is approved, the permittee must compensate Provo City for the appraised value of the tree removed, either by replacement or by monetary payment. Section 9.20.110 provides that any person who destroys or injures a Provo City tree must pay the appraised replacement or repair cost. Section 9.20.120 is devoted to tree appraisal as its own subject.
The method is specified rather than left open: appraised value is determined by an ISA certified arborist with tree appraisal training, using accepted International Society of Arboriculture and Council of Tree and Landscape Appraisers procedures.
That matters because professional tree appraisal does not value a tree at the cost of a sapling. It accounts for species, size, condition and location, and for a large, healthy, well-placed shade tree the resulting figure can substantially exceed what the homeowner paid the crew to take it down. We are deliberately not printing a dollar range here, because a credible one does not exist in the abstract — the number is produced by an appraisal of a specific tree, and any figure quoted without one is invented.
The lesson is procedural rather than numerical. The cost of asking first is a phone call. The cost of not asking is set by someone else, after the fact.
Hiring a crew: what to verify
For work on a public tree, Section 9.20.050(1)(a) sets a floor. The permittee must abide by the city's arboricultural standards and specifications, along with any specific conditions or methods the City Forester requires, including both ANSI standards and best management practices. And each crew performing contract work on a public tree must have at least one ISA certified arborist on the crew and on site while the work is performed.
Note the construction: on the crew and on site. A company with a certified arborist who quoted the job from an office does not satisfy it.
For a tree entirely on your own property, that requirement does not apply — which is precisely why it makes a good screening question anyway. A company that can put a certified arborist on your driveway is a company that meets the city's standard for its most regulated work.
Beyond certification, four things are worth confirming before anyone climbs:
- General liability insurance, verified by a certificate sent directly from the insurer rather than a photograph of one.
- Workers' compensation coverage. This is the exposure most homeowners underestimate. Tree work involves chainsaws at height; an uninsured climber injured in your yard is a problem that finds its way to you.
- State licensing status, checked on the Division of Professional Licensing's public license lookup rather than taken from the company's own marketing. Whether a license is required turns on the scope of the work, so look it up rather than reason about it.
- A written scope that states explicitly what happens to the wood, the brush and the stump. Stump grinding is very often a separate line item, and "removal" in a verbal quote frequently means the trunk leaves and the stump stays.
Storm damage, hazard trees, and who moves first
Chapter 9.20 has a section for the emergency case. Section 9.20.130, Trees – Dangerous or Hazardous Conditions, gives the city latitude it does not have in ordinary circumstances: it may trim or prune any public tree, or remove any tree planted in violation of the chapter, without serving notice on the abutting property owner. The same section prohibits interfering with the City Forester, or anyone acting under the Forester's authority, during removal work along any street or public place — and extends that prohibition to other forestry activities including planting, mulching and pruning.
In a windstorm, this is the section that lets crews clear a street at two in the morning without a paperwork trail first. It sits alongside the rest of the city's severe-weather posture.
For a hazardous tree on private property, the calculus is yours, and the honest guidance is that hazard is a technical judgment rather than a visual one. Dead limbs in the canopy, a lean that has changed, mushroom conks at the base, cracks in a major union, or heaving soil on one side of the root plate are all reasons to get an arborist's assessment rather than a removal quote. Those are different products: an assessment tells you whether the tree needs to come down, and a quote assumes it does.
Construction is where the expensive mistakes happen
If you are building an addition, replacing a driveway, running a new sewer lateral or having a utility trench cut, Chapter 9.20 has specific requirements and they are easy to miss because they land on the contractor rather than on you.
Section 9.20.110(3) requires that a public tree in the immediate vicinity of excavation, demolition or construction be protected from unnecessary injury. Tree protection specifications and standards must be obtained from the City Forester and strictly followed, a tree protection zone must be established per the city's arboricultural standards, and protection must be coordinated with the City Forester throughout the project. During the construction phase, the contractor must ensure regular and adequate irrigation of each public tree — and that irrigation must be documented.
A documentation requirement in an ordinance is a signal. It exists because someone, at some point, said they had watered.
Limbs overhanging a roof are their own maintenance question — they abrade shingles, fill valleys and gutters with debris, and shorten the life of a covering you paid for; our guide to roofing in Utah Valley covers what that damage looks like and when it matters.
Root damage from trenching is the classic failure here, and it is worth folding into the same planning as any other home-services contractor decision on the property; and it is delayed: the tree looks fine through the project, thins the following summer, and dies the year after. By then the connection is obvious to an arborist and invisible to everyone else. Put the tree protection zone in the contractor's scope in writing, before the equipment arrives.
The registers, and why they exist
Two of the chapter's last sections are easy to skip and worth knowing about. Section 9.20.160 establishes a Heritage Tree Register and Section 9.20.170 a Big Tree Register.
Their direct effect on a homeowner's removal question is narrow — but a listed tree is another reason to make the call before making the cut, and their presence in the ordinance tells you something about the posture behind the rest of it. A city that keeps a register of its notable trees is a city that will appraise one when it is lost.
What to do, in order
- Establish whose tree it is. Sidewalk to curb, or in a park: assume public until the city says otherwise. Behind the sidewalk: yours. No formal park strip: yours to maintain out to the curb.
- If there is any chance it is public, call Provo Power's forestry office with the address. Ask whether it is a city tree and what the process is for what you want to do.
- Do not let a contractor make this determination. They are quoting the job, not researching title, and the liability under Section 9.20.110 lands on the person who caused the work to be done.
- For a private tree, get an assessment before a quote if the question is whether it is dangerous.
- Verify insurance, workers' compensation and licensing before anyone starts, and get the stump, wood and brush in writing.
- If it is a public tree in your strip, water it. That is not advice. It is Section 9.20.050(2)(a).
The whole of Chapter 9.20 comes down to one idea that is genuinely counterintuitive: on a Provo street, the tree in front of your house is a piece of public infrastructure that you are expected to look after and not allowed to alter. Once you hold both halves of that at the same time, the ordinance stops seeming strange and starts seeming like what it is — a fairly ordinary arrangement for a shared asset that happens to be growing in your front yard.
