Information
This report is concerning one (1) Coast Live Oak (Quercus agrifolia) tree. The tree is located at 11532
Bianchini Ln, Cupertino, CA 95014. The tree is near the south west corner of the property, between the
driveway and fence, below high voltage power lines. This property is called Murano HOA and is
managed by Community Management Services. For the remainder of this report, Murano HOA will be
referred to as the client property.
Assignment On December 18, 2019 I was asked by the client to inspect and evaluate the coast live oak tree on the
property. I was asked to make recommendations.
A. Coast Live Oak Quercus agrifolia 16 DBH
Observations The oak tree appears to be a volunteer tree possibly planted by a squirrel.
The tree has been planted in a
poor location.The high voltage power lines will soon interfere
with the growth of this oak and the tree
will be topped for years to come. The trees trunk is also starting to encroach on the neighboring fence
and causing damage. The mature size of a coast live oak can exceed 70 high and 70 wide. This tree
has been growing in a 3 planter. The tree will soon outgrow its space. Lastly, the base of the trunk is
showing signs of Phytophthora, a water mold that can lead to the death of a coast live oak.
Please see photos in Attachment I for further observations.
Testing and
Analysis
There was no soil, tree or other physical testing.
Discussion This oak tree has been under the observation of A Plus Tree since 2016. Over the past few years the tree
has started to decline. There are signs of phytophthora wounds on the trunk. There are also several large
pruning cuts. This may have contributed to the further decline of this tree. The fact this tree has been
growing under the power lines is a hazard to the community as well as the tree. High voltage power
lines have been known to cause fires and even death. This tree is planted in the wrong place and we
would like to plant elsewhere on the property where a few large trees can thrive.
Recommendations
The future for this tree is grim. It is best that A Plus removes this coast live oak and replaces it with two
blue oaks in a large lawn area elsewhere on the property.

Dark bleeding sores on the
base of the tree is a sign of
sudden oak death. This has
led to canopy loss and tip
dieback. TR-2020-002
