Background Information
This report was prepared on behalf of Cushman & Wakefield Residential and Plum Tree
Park and is concerning one (1) Lombardy Poplar (Populus nigra 'Italica')located at 200 SW
5th Pl, Renton, WA 98057.The report has been requested because the tree is dead, and they
are concerned about tree parts falling onto nearby structures, cars and/or people.I have
been asked to perform an assessment and provide recommendations.Cushman &
Wakefield Residential and Plum Tree Park are seeking to obtain a tree removal permit for
this tree. The assessment was performed on August 24, 2024.

Observations
aplustree.com A Plus Tree, LLC
At the time of the assessment, I observed the following (please also refer to the photo
below):
780 Azuar Ave. Vallejo, CA 94592
•Lombardy Poplar (Populus nigra 'Italica')
•The tree has a DBH of 50.3 inches.
•The height of the tree is approximately 40 feet tall.
•The tree is fully exposed to prevailing winds.
•There is 100% canopy loss.
•The tree has weak attachments.
•There is a history of branch failures.
•The tree is within striking distance to dumpsters,
carport, cars and people using the road.
The assignment is to perform a visual assessment regarding health condition, structural
integrity, a threat of pest/disease and potential hazards, and to provide recommendations
for future action. This visual inspection was from ground grade only.
Assignment
Testing & Analysis
There were no soil, tree or other physical testing.

Discussion
Lombardy poplars (Populus nigra 'Italica') are a non-native tree species that has a short
lifespan of approximately 30-50 years. They are fast-growing and can reach mature heights
upwards of 70 feet.For this reason, they have brittle branches that can fall during strong
winds, creating projectiles that can be 10 feet long. This species is also susceptible to
stem canker disease (Dothichiza populea) which is caused by the microorganisms known
as Crytodiaporthe populea. Upon visual inspection of this Lombardy poplar, I observed
several structural defects and conditions that increase the likelihood of failure and reduce
the tree’s structural strength. They are as follows:
No living tissue – The tree is completely dead with no live tissue.
History of branch failure – There is evidence of large branch failure with similar branches
present.
High Target Zone – This tree is located next to important targets include cars, people in the
area, carport and garbage enclosure.Were failure of this tree or one of its parts to occur,
the damage would be significant to severe.
The individual defects listed above indicate serious structural problems and, in my
assessment, the likelihood of failure is imminent, meaning that failure of a stem or
branches may be expected under normal conditions in the near future.The likelihood of
impact is high, and the overall tree risk rating is high.
Recommendation
This tree has no live tissue and no chance of recovery. As time goes on it will continue to
lose large branches that could cause damage to structures or cars, and injury to people that
are nearby. The most reasonable approach to mitigate the hazard is to remove the tree
completely.

Arborist Disclaimer
Arborists cannot detect every condition that could possibly lead to the structural failure of a
tree. Trees are living organisms that may fail in ways we do not fully understand. Conditions
are often hidden within trees and below ground. Arborists cannot guarantee that a tree will
be healthy or safe, or fail for that matter, under all circumstances, or for a given period of
time. Likewise, remedial treatments, like any medicine, cannot be guaranteed.
Treatments, pruning and removal of trees may involve considerations beyond the scope of
the arborist’s services such as property boundaries, property ownership, sight lines,
disputes between neighbors, landlord- tenant matters, etc. Arborists cannot take such
issues into account unless complete and accurate information is given to the arborist. The
person hiring the arborist accepts full responsibility for authorizing the recommended
treatment or remedial measures.
Trees can be managed, but they cannot be controlled. To live near a tree is to accept some
degree of risk. The only way to eliminate all risks is to eliminate all trees.
This consultant does not verify the safely or health of any tree for any period of time.
Construction activities are hazardous to trees and cause many short and long-term injuries,
which can cause trees to die or topple.
Even when every tree is inspected, inspection involves sampling; therefore, some areas of
decay or weakness may be missed. Weather, winds and the magnitude and direction of
storms are not predictable, and some failures may still occur despite the best application of
high professional standards.
I hereby declare that the above observations, discussion and recommendation are true to
the best of my knowledge, belief and professional opinion. In addition, A Plus Tree is held
harmless of any of these opinions from future tree failures.
Sincerely,
