The number of healthy trees permitted for removal by the City Arborist Division surged by 40% in 2023, according to the City's published tree data, resulting in a 121% increase in annual tree loss since 2020. Before 2020, the City reported fiscal year (FY) tree data, which showed no growth trend between FY2014 and FY2019. Additionally, there was no growth in healthy tree loss in calendar year (CY) 2020, but after 2020, healthy tree loss began to rise sharply year over year.

Chart note: Before 2020, tree loss data was provided only by fiscal year (FY), from July 1 to June 30.
The actual growth in permitted healthy tree loss since 2021 could be even higher, as data before the 3rd quarter of 2022 might have been inflated due to a programming error that double-counted trees when a Plan Review permitted trees in more than one quarter.*
The City Planning Commissioner, Jahnee Prince, has requested that the Arborist Division stop publishing tree loss data until the Accela program team releases their new, interactive dashboard format for quarterly reports. While we are delighted that efforts are underway to provide the public with more user-friendly access to tree data, it is now five months after their initial projected release date, and there's no release date. This delay is particularly concerning as we are currently in Phase 2 of the Tree Ordinance Rewrite process without access to the most recent or corrected historical data.
Where Are We Losing the Most Trees?
As the 2023 quarterly reports were being released, we noticed a record high of tree loss in the 3rd quarter and asked Arboricultural Manager, David Zaparanick, to investigate if some of these trees might not have been lost on larger commercial and multi-family housing projects. David provided the following information for the first three quarters of 2023 but has not yet given details for the 4th quarter of 2023. The information he provided shows that the majority of trees are coming down on just a handful of commercial and multi-family housing projects.
Our Tree Ordinance currently focuses on preserving trees on lots zoned as single-family residential, which account for 77% of our tree canopy. However, this focus misses that the majority of our tree canopy loss is now happening on multi-family and commercial developments, and we may need to strengthen the Tree Ordinance's protection in those zoning categories.
We are unable to delve deeper into the quarterly report data to identify trends based on location or project type for tree removal. The only tree-permitting data publicly available is the Accela permitting database which allows us to look up the tree loss by individual permit only.
Here is a description of the larger projects that caused the most significant tree loss in the first three quarters of 2023:
1st Quarter:
In total, 62% of the trees permitted to be removed in the first quarter were on just five properties.
2nd Quarter:
In total, 47% of the trees permitted to be removed in the second quarter came from a single project at Tyler Perry Studios.
3rd Quarter:
In total, 69% of the trees that were permitted to be removed in the third quarter were on just three properties:
*It was discovered in the summer of 2022 that whenever additional trees were added to a Plan Review (construction) permit in a quarter following the quarter the initial permit was issued, the subsequent quarterly report recounted all the trees that had been permitted the prior quarter. Also, some trees were removed for infrastructure purposes and left off the quarterly reports. The Arborist Division was supposed to have the data for all quarters before 3rd quarter of 2022 corrected and republished by year-end 2023. As of May 2024, that data still has not been corrected and no data has been released for the most recent quarter (1st quarter of 2024).
