As part of ongoing wildfire debris cleanup efforts, the U.S. Army Corps of Engineers (USACE) has begun removing trees in Altadena that pose a threat to public safety. However, after concerns from residents over the potential loss of historic and ecologically valuable trees, officials have clarified that tree removal will be carefully assessed and balanced with preservation efforts.
How Are Trees Being Assessed for Removal?
Col. Sonny Avichal, who leads the USACE cleanup, emphasized that only trees posing a clear safety risk will be removed. Certified arborists are conducting evaluations based on several factors:
- Canopy and root damage
- Potential fall zones
- Likelihood of death within five years
“We recognize the value trees have in the Altadena community and that we must take a balanced approach that errs on the side of preserving trees as much as possible,” Avichal stated.
Resident Concerns Over Historic Trees
For many Altadena residents, the trees are more than just greenery—they are living landmarks that provide shade, support local wildlife, and represent a deep connection to the area’s history.
One resident, Bonnie Schindler, expressed concern about losing her century-old trees:
“The trees being the last thing here, it makes them so much more important. I don’t want to have to fight for them, but I will.”
Schindler’s personal arborist concluded that many of her trees were not severely damaged and could potentially survive without being removed.
USACE’s Commitment to Property Owners
In response to the public outcry, the USACE has committed to working closely with homeowners throughout the cleanup process. Here’s what residents can expect:
- Walkthroughs with homeowners: Before any tree removal begins, property owners will be consulted.
- Consent required: The USACE must receive signed consent from homeowners before removing any tree on private property.
- Right of Entry forms: Property owners can request that certain trees remain untouched by noting it on their forms.
- Advance notice: Residents will be given at least five days’ notice before any debris or tree removal begins.
“I was assured that property owners would be given at least five days’ advance notice before debris removal begins, along with the opportunity to understand whether a tree on their property has been deemed unsafe or requires removal,” said Supervisor Kathryn Barger.
How Will Hazardous Trees Be Marked?
To avoid confusion, trees that have been officially deemed hazardous by USACE arborists will be clearly marked:
- A unique barcode
- Three blue dots painted on the tree’s trunk
This marking system will help both residents and contractors quickly identify which trees are scheduled for removal.
