Tree Protection Ordinance 1.0

What could be more mind-numbingly boring than reading a blog post about a local ordinance?

And yet here I am, asking you to do so, because the City of Atlanta is revising its tree protection ordinance, and that’s a big, big deal if you’re fond of drinking clean water, breathing clean air, and not being burned to a crisp every summer.

Anyone still reading? Okay, here’s what I’m going to try to do.

  1. Tell you something about how Atlanta currently protects trees.
  2. Set out the rudiments of the proposed changes to our law.
  3. Explain how you can help ensure the best possible outcome of this process.

Part 1: Tree Protection in Atlanta

In 1977 — the year UGA lost to Pitt in the Sugar Bowl, Jimmy Carter became president, the L5P Community Pub opened for business, and Bobby Cox was hired to manage the Braves — Atlanta adopted a law regulating tree removals. It’s been revised several times since then. The principle of the tree protection ordinance (TPO) could not be simpler: most of Atlanta’s trees may be privately owned, but they’re also a public good like clean air. The basic mechanism to protect Atlanta’s trees is simple, too: require those who remove trees to seek approval from the city and then replant on site or, if that’s not possible, to pay into a fund that can provide money for replanting of trees elsewhere in the city.

In a sense, everything else about the ordinance is just details. The fundamental principle and mechanism have been in place for years. In a different sense, everything has changed since the TPO’s early days. Here are just a few of the things that are different today versus yesterday:

  • The city has fewer trees than in 1977.
  • The metro area has many more people and much more pavement than in 1977.
  • Average temperatures are hotter, due to climate change and the urban heat island effect.
  • The required payment (“recompense”) for tree-removal-without-replanting no longer appears to function as a strong incentive to preserve as many trees as possible or as a strong deterrent to unnecessary removal of trees. For some developers, it’s just the cost of doing business.
  • Enforcement of the ordinance by the city is hampered by inadequate staffing and bureaucratic inefficiencies.
  • Money in the Tree Trust Fund has been siphoned off for many ancillary purposes, e.g., to pay the salaries of city arborists.
  • The growing complexity and spotty enforcement of the law increasingly frustrate and befuddle the public.
  • We know a LOT more about the ecology of urban forests and the ecosystem benefits of trees than we used to know.

Atlanta has lost and continues to lose trees in the years since the ordinance was enacted. A 2001 report by American Forests, focusing on the center of the wider metropolitan area, found that heavy tree cover (>50% of land surface) had declined from 47.5% in 1974 to 26.4% in 1996. In 2012, two researchers found that over the five-year period they chose to study, Atlanta lost trees despite the ordinance. Georgia Tech’s tree canopy research indicates that as of 2014, about 48% of the city has tree canopy.

Is Atlanta’s existing TPO a dud, a failure, a travesty? Not at all. Despite everything, it’s done some great work for us. Without it, we would certainly be in much worse shape. But we do need a reset.

Part 2: Draft TPO 1.0

The city released its first draft of a rewritten ordinance in March. This work on the ordinance is being done within a broader planning process known as the Urban Ecology Framework (UEF), which is itself part of a still broader plan for Atlanta called the Atlanta City Design, completed in 2017.

I have served as a member of a UEF stakeholder committee. Our committee contributed ideas first to a kind of concept plan for future green spaces, green connections, and green policies in Atlanta. Then work on the ordinance began, in which our committee has been much less involved. The schedule for the rewrite continues until August, as you can see below.

The headline of my interim report to you on Draft TPO 1.0 is as follows: it’s a missed opportunity. The city and its consultant Biohabitats have made the ordinance even more complicated, without clear improvements that promise more scientific, more effective protection for our trees and tree canopy.

What follows is my attempt to summarize in part what has been offered to the public. Please know that it is imperfect and incomplete. Why? Partly because the process has been highly imperfect, with key changes mid-process within the city’s planning team; subpar communication and followup with the technical and advisory committees; and release of this draft version without any annotations or without redlining to reveal the proposed changes from the existing ordinance.

It’s also imperfect and incomplete because this is a highly technical, 50-page document, encompassing minutiae on tree valuation, tree density, preservation thresholds and incentives, reasons for removal, notifications and posting, appeals process, parking lot requirements, and much, much more. Frankly, some of it is beyond my competence to assess, and it’s far beyond my ability to summarize here.

In any case, here are some highlights.


Broadly speaking, this “new “ordinance amounts to a tweaking of our existing ordinance. The city has NOT started from scratch. Instead, it has simply altered the existing ordinance.

Note that other cities have taken a more holistic and thoroughgoing approach to improving protection of their trees and forests, by better incorporating current scientific knowledge and making better use of zoning. For example, in our nation’s capital, site designs for construction are required to achieve a certain score, varying by zoning district and calculated by the green elements selected and the area of the site they cover. A number of different green elements qualify for what’s called the Green Area Ratio including permeable surfaces, vegetated roofs, bioretention, and trees.

Washington, D.C.’s Green Area Ratio



The stated goal is “to protect and advance a high-quality urban forest within the boundaries of the city and slow or halt canopy loss.” That is, the city is committing itself only to slow canopy loss.


It is the intent of this Article to prevent the clearing and removal of all trees on a lot for construction or landscaping. Permits to allow removal of all trees on sites that contain 3 or more healthy (i.e., non-invasive/undesirable) trees, not including hardwoods less than 6-inch DBH and pines less than 12-inch DBH, will be reviewed by the City Arborist and referred with their recommendation to the Tree Conservation Commission for final approval or disapproval. Tree Conservation Commission hearing procedures apply.


A major addition to the existing ordinance is that trees will now be assigned to a significance category. More significant trees get more protection; less significant trees get less protection. The new ordinance creates a weighted point system for tree attributes (e.g., species? native or non-native? age? size? condition? etc.); ecological and site factors (e.g., grove presence? grove age? riparian buffer? floodplain? steep slope? etc.); and project type (linear infrastructure? mass transit? affordable housing? urban agriculture? handicapped access? etc.) .

Category 1 has the lowest significance (e.g., tree is dead, diseased, hazardous, etc.) and Category 5 has the highest significance (i.e. tree provides the highest environmental services, is specially designated as historic or specimen, etc.).

These new categories affect tree protection in a variety of ways throughout the proposed revision. For example, the higher the significance of a removed tree, the more trees that must be replanted / the greater the recompense payment as determined by the ordinance’s formula.

These screenshots from presentations made by the city suggest how the significance categories could affect tree protection:

That some trees are more valuable than others — in that they provide a higher level of ecosystem services, more support for wildlife, and so on — is inarguable. So it’s a good thing that the new ordinance would distinguish between a 20-inch white oak in a floodplain and a 20-inch tree of heaven in a kudzu patch.

More analysis will be needed to determine whether the city is providing enough protection for trees of lower significance, and how trees will be categorized in practice — for example, at present the city envisions having the property owner evaluate tree significance and fill out a form (see this working example) that must be submitted with the permit application, a process that seems absurdly unworkable and open to widespread abuse.


Atlanta’s existing ordinance does allow for the removal of some healthy trees. The most obvious example is in the case of smaller trees (<6″ in diameter) on private property, which the government does not regulate at all. And obviously, healthy trees in the buildable area of a lot can be removed, provided that the developer or building owner applies for a permit and agrees to replant or pay recompense.

The existing ordinance also allows for the permitting of some removals without requiring any replanting or recompense, as in the example of trees growing near the foundation of a house or in the case of certain undesirable tree species.

Draft TPO 1.0 creates some new justifications for private property owners to remove healthy trees.  Here are a few examples:

  • Once every three years, a property owner can remove a healthy tree or trees (up to 5% of the total inches of diameter on site) for any reason, provided that certain conditions are met and the tree is not Category 4 or 5.
  • Property owners may apply for a permit to remove a healthy tree of any category if it is causing “severe hardscape damage” or is in “significant conflict with overhead and underground utilities.”
  • Property owners may also remove a tree if it poses imminent danger to property, provided that the owner applies for and is granted a permit after the fact.

An argument exists that these new allowances and exemptions are unnecessary or imprudent as written. Why allow a property owner to remove an otherwise healthy, large, mature tree on a whim? What does “severe hardscape damage” really mean — not cracks in a homeowner’s driveway, surely? Does “imminent danger to property” include danger to a birdbath?


Draft TPO 1.0 makes no change in two areas of significant concern to people who care about Atlanta’s trees.

The proposed ordinance splits jurisdiction over privately owned and street trees, on the one hand, and trees in parks, on the other, between City Planning and the Office of Parks, respectively. Many of us believe that one unified staff of arborists within city government should be given responsibility for all trees in the city. There appears to be no rationale for the division other than the bureaucratic organization of Atlanta’s government.

The proposed ordinance also continues to divert money intended for replanting into other uses. These include:

  1. Up to $50,000 for administering the ordinance.
  2. Up to 5% of the money added to the fund the previous year or $100,000, whichever is greater, for educational materials.
  3. Up to $110,000 per year for the salary and benefits of two (2) arborist positions in the Department of City Planning.
  4. Up to $75,000 annually for the salary and benefits of an arborist senior/project manager position.
  5. Up to $200,000 per year for the salary and benefits of a tree pruning crew, consisting of one forestry crew supervisor, one tree trimmer senior, and one tree trimmer.
  6. Up to $60,000 per year for the salary and benefits of an administrative analyst
  7. An undefined amount annually for the salary and benefits of the clerk of the Tree Conservation Commission.

These administrative and operational expenses are draining up to $600,000 from other uses of the Tree Trust Fund, namely, replanting, acquiring forest land, purchasing forest easements, maintaining trees in parks, etc.


Provisions of Draft TPO 1.0 open up a number of opportunities for the City of Atlanta to set aside the requirements of this law. The rationale on paper may seem plausible, but in practice, there is potential for abuse.

One example is implementation of the Atlanta City Design of 2017, which envisions intense development and higher population density along north-south and east-west axes in the city.

And so, “to promote new construction or substantial reconstruction in City Design Growth Areas, the City may reduce site density levels and preservation thresholds for non-single- family zoning categories by 50% for projects planned in the City Design Growth areas.” Roughly speaking, then, even fewer trees in places where the urban forest has been most reduced in the past several decades, in exchange for more trees on the periphery.

Atlanta’s tree cover as of 2008

Also functioning as loopholes, and already mentioned above, are projects that the city deems important enough to justify modifying the proposed ordinance, e.g., mobility improvement, mass transit, affordable housing, “green” building, stormwater management, handicapped access, solar access, etc.

Part 3: How You Can Help

As you can see from the calendar above, in July and August the City Council and the NPUs are slated to take up the final version of the proposed TPO. Letting Amir Farokhi know — now or later — that you want a stronger ordinance and do not want to see the city weaken protections for our trees would be so great!

Fear of Trees

Everything is connected — remember that, and I’ll come back to it in a moment.

I grew up in a small town in rural Georgia. Really small: not even 2,500 people (i.e., about half of Inman Park’s population). In those days and in that part of the world, children spent a lot of time outdoors. Lots and lots of time outdoors.

From an early age, therefore, older people were continually instructing us in the proper evaluation of risk. Mommy and Daddy were not going to be around to protect us from each and every danger: we children had to learn for ourselves how to live a full, active life with an acceptable level of risk.

This is a poisonous snake; that one isn’t. This is poison ivy; that’s Virginia creeper. Don’t you ever point a gun — even an unloaded gun, even a toy gun — at another person. “No” to getting into water until we could swim and swim well. What’s more, we were instructed never to dive headfirst without knowing exactly what was below the surface. We knew to be prompt about cleaning and disinfecting all wounds. We learned deep respect for fire. We were taught that an animal with rabies behaves such-and-such a way …

And so on.

Even so, people were killed and injured in the woods and fields around my hometown, just as they are every week on I-285 and the Downtown Connector. I remember the awe in my father’s voice when he told me about a man who was sitting in his pickup on the shoulder of a road. From behind him, a logging truck came rumbling by. At just the wrong moment, one of the logs rolled off the top of the pile, smashed through the back window of the man’s pickup at 55 mph, and decapitated the unfortunate fellow.

I think about all of that when I encounter neighbors who are afraid of trees growing near their homes.

“It’s just a tree. I’m a human being. My spouse and our children are humans. As far as I’m concerned, there is no level of danger that is acceptable to me. None at all. That tree needs to go. Why should I have to worry about it being blown over onto my house? It’s just a tree.”

That’s what I imagine they’re thinking. And on one view, it’s very hard to argue with that way of thinking.

It’s just a tree, after all, and it’s just one tree.

We live amid danger. Danger from bad drivers. Danger from lightning and flooding. Danger from criminals. Danger from aggressive dogs. Danger from high summer temperatures. Danger of contracting an infectious disease. Danger of getting fired or laid off. Danger of becoming anxious or depressed. Danger of losing a spouse or child. Danger from terrorism and nuclear weapons and unhinged politicians.

Amid so many dangers in life, even I can understand the appeal of eliminating the risk posed by that large tree. And if I make the effort to imagine what it is like not to have grown up learning how to tell the difference between a cottonmouth moccasin and a harmless watersnake, I can manage to be more sympathetic to those neighbors of mine who have a different tolerance of risk with regard to an oak that will fall one day (or a mosquito that may be spreading disease, which is a topic for a different day).

All that said, let me leave you with two thoughts.

First, unlike an animal, which will fight tooth and claw to live, a tree will die without apparent protest, without a sound. And yet you are connected to that tree in profound, complex, essential, and still mysterious ways. I’m not being spiritual here. The clean air you breathe, the clean water you drink? Gifts from our forests. Ponder that, the next time you hear the whine of a chainsaw.

Second, I do get a little angry when I sense that any of my neighbors is insufficiently concerned about the impact of “small-decision effects.” That’s a fancy way of saying that if everyone cuts down all of his or her larger trees, we’re all going to suffer. Which is another way of saying that some people, sadly, are very happy for me to tolerate risk from a large tree, so long as they don’t have to.

Life, in significant part, is one long effort to manage risk, in such a way that we neither die as a consequence of recklessness, nor fail to live fully as a consequence of timidity. We need our urban forest, friends — so please keep making an effort to find that happy medium between unnecessary fretting and blithe unconcern (which, fortunately for us, a good arborist can help us with).


Inman Park has been working closely with Trees Atlanta for at least two decades. Their entire organization collaborates with us to plant and maintain new trees, as well as to educate and raise awareness among our residents. In any given year, Trees Atlanta might commit tens of thousands of dollars to our neighborhood.

Relying upon the generosity of Inman Park, which is expressed partially through IPNA’s budgeting of funds and partially through eager responses to fundraising by Tree Watch, we are able to make an annual donation to Trees Atlanta.

Shown here on Monday, June 10, at the Trees Atlanta Kendeda Center are (L-R) Tree Watch’s Steve Hays, Chief Program Officer Greg Levine, Marge Hays of Tree Watch, and Chief Operating Officer Connie Veates.
