ARBORIST REPORT
On May 2nd, 2019, I inspected the trees at 23010 Crickett Hill Road in Cupertino,
California 95014. Although the recommendations in this report are based on sound and
accepted horticultural practices, the author cannot be held responsible for the f inal
outcome of the recommendations or any liabilities associated with this project. Tree
inspections, in this case, do not cover all internal cavities, condition of the root system
nor non-visible structural defects or disease.
Please consider my observations as noted below:
Tree # 1 –
Subject tree – Sequoia – Redwood tree
DBH – 22 inches
Height – Approximately 40 feet
Canopy Spread – Approximately 25 feet
Observations – The Redwood tree is in very good health. On a scale of 1 to 10, 10
being the optimal health, I would give it a 8. The roots are concerning as the trunk of
the tree is roughly 25 feet from the building and there are stress cracks on the garage
floor.

The only way to know for sure if it is the roots of the tree in fact causing the damage is
to perform a root inspection which requires an air spade to loosen up all the soil. A t
that point and time one can see if there are roots that need to be cut, etc.. There is a
root barrier in place which is encouraging, although I suspect over time the
effectiveness of the barrier has been compromised. I am not in favor of removing a
healthy tree unless it is the cause of the damage and it can not be mitigated in another
way.
Tree # 2 –
Subject tree – Liquidambar – Sweet Gum tree
DBH – 18 inches
Height – Approximately 40 feet
Canopy Spread – Approximately 20 feet
Observations – The Sweet Gum tree has been significantly root pruned in the past,
therefore I am not confident any damage to the concrete slab is a result from the roots
of the tree. The tree would be rated an 8 on a scale of 1 to 10, 10 being the optimal
health. Air spading for a root inspection is not an option for this tree because of the
root zone. I do not recommend cutting additional roots as it would compromise the
integrity of the tree, instead I recommend structural pruning of the tree. Removal of the
trees seems like a drastic move.
