Assignment:
The Burlingame City Council has requested a complete assessment of the large blue gum
eucalyptus at the above site. Burlingame requested the assessment be carried out by three
independent Certified Arborists who have vast experience and knowledge in this field.
The three arborists shall have no connections to any persons or, groups that would alter
their opinions of this tree. Specialized equipment for the root crown excavation and
examination will be used by the arborists to ensure the least amount of trauma to the
inspected areas. A thorough analysis will be conducted on the findings. The arborists
will provide the council with their fmdings in the form of a written report. The report is
expected by the City in time for a complete review prior to the city council meeting on
May 7, 2007. Photographs of the process will be included with the report in the form of a
compact disc. A representative of the arborist team will be present at the council meeting
on May 7, 2007 to explain the findings and answer any questions.
The Certified Arborists who were chosen to complete this assignment are:
♦ Michael Santos of Hortscience of Pleasanton, CA
o Certified Arborist # WE-3877
o Registered Consulting Arborist #430
♦ Robert Weatherill of Advanced Tree Care of Redwood City, CA
o Certified Arborist # WC-1936
♦ Kevin Kielty of Kielty Arborist Services of San Mateo, CA
o Certified Arborist # WE-0476A
All three arborists have many years of experience and are considered experts in the areas
of arboriculture. The three arborists chosen for this project were approved by Bob Disco,
arborist and contact person for the City of Burlingame.
1800 Easton Dr./4/23/07 (2)
Method:
The root crown of the blue gum was excavated to expose the large buttress roots.
Approximately 12 inches of soil was removed to a distance of 3 feet from the trunk. This
work was carried out over a 2 day period, using shovels, picks, electric jack hammer,
compressor and an air spade.
The root crown was inspected using a wooden sounding mallet, and a resistograph, a rod
that helps to detect soft spots inside the tree, was used to identify possible decayed areas.
A visual inspection of the root crown and lower trunk was also carried out. Following
the inspections, it was deemed unnecessary to have samples analyzed at a plant
laboratory.
The foliar canopy was thoroughly inspected. Due to the extreme height of the tree the
tree was climbed. The climber accessed the tree by way of the aerial lift truck provided
by the City. A.N.S.I. approved climbing ropes and saddles were used for the accent. No
climbing gaffs were used at any time for this inspection. Visual assessments were taken
and decay was tested by probing the surfaces of old pruning wounds.
The methods will be explained in further detail in each arborist's report.
Time line:
The assessments and excavation were carried out in a 10 day period, from April 9 to
April 18, 2007.
♦ Monday, April 9, 2007 - Robert Weatherill climbed and inspected the
blue gum tree's canopy. Kevin Kielty assisted from the aerial lift truck.
♦ Thursday, April 12, 2007 - Robert Weatherill and Kevin Kielty exposed
the root crown on the sidewalk side.
♦ Monday, April 16, 2007 - Robert Weatherill and Kevin Kielty exposed
the root crown on the street side.
♦ Tuesday, April 17, 2007 - Michael Santos examined the root crown.
Robert Weatherill and Kevin Kielty observed.
♦ Wednesday, April 18, 2007 - Kevin Kielty inspected the backfilled site.
Photographs were taken at each stage of the inspection. Persons with information as to
the history and maintenance of the tree were interviewed. The City of Burlingame's staff
including members of the tree crew was quite helpful during this process.

Summary:
The three Certified Arborists selected for this project completed their assignment in a
timely and professional manner. Their reports describe the work-andiithe testing -in ra clear
and concise manner. As the lead arborist on this project, I was on site for all
examinations and excavations. The three arborists hired for this project have discussed
and agreed on each others findings. We are also in agreement that at this time there is no
need to incorporate additional decay assessment tools.
In his report, Michael Santos has outlined tree protection guidelines if road work is to be
carried out. I would like to emphasize the importance of having an arborist on site during
any excavation near the root zone of this tree. This work can be carried out by the
Burlingame staff arborists or by an independent licensed certified arborist.
In his report, Robert Weatherill has outlined future pruning specifications. These
specifications should be incorporated into future contracts for tree maintenance.
The excellent care this tree has received over the years and the diligence of the
Burlingame Parks Department has contributed to this large trees favorable report.
Continued maintenance of this tree is critical to ensure the health and safety of the tree.
Despite the quality of care this tree receives, living near or below large trees has its
inherent dangers. This report by no means guarantees the future health or safety of this
tree. This report is to be used as a guideline for the City of Burlingame.
The information included in these reports is believed to be true and based on sound
arboricultural principles and practices. The report is intended for use by the City of
Burlingame only. Use of this report by others will require permission from the City of
Burlingame and the Certified Arborists who have collaborated in the writing of this
report. The arborists hired for this assessment have not discussed their findings with
unauthorized persons or parties.

Subject: Blue gum evaluation
1800 Easton Dr.
Dear Mr. Kielty:
The City of Burlingame is responsible for maintaining a mature blue gum (Eucalyptus
globulus) located at 1800 Easton Dr. The City staff is concerned about the health and
structural stability of the tree. You asked HortScience, Inc. to be part of a team of
consulting arborists. HortScience was asked to evaluate the condition of the lower trunk
and root collar, and make recommendations as appropriate.
I visited the site with the City of Burlingame staff, Robert Weatherill, Advanced Tree Care
and you on April 17. This report summarizes my assessment and recommendations.
Methods of Evaluation
I evaluated the health and structure of lower trunk and root collar based on a visual
inspection of external conditions. You had excavated soil from the base of the trunk to
expose the root collar. The tree was examined for decay indicators, including:
• Cavities;
• decay conks or mushrooms;
• bleeding along trunk;
• old wounds.
I also tested the tree at several locations with the Resistograph®, a decay detection
device. This tool pushes a 15" long by 2 mm diameter needle through the wood and
records the resistance to penetration on a graph. Sound wood appears as a jagged line
increasing in height on the graph, while a straight line at the bottom represent cavities.
Decayed wood tends to be straight or wavy lines low on the graph.
Observations
The blue gum was located in front of the Easton Branch Library and was tagged as #37.
The tree was in a 15' wide planting area between Easton Dr. and the sidewalk. The base
of the trunk had grown over the top of the curb. A damaged section of street had been
removed to assist in examination of the root collar.

Tree canopy
The tree appeared to be in
good condition, and
mature in form and
character (photo 1). It had
an 85" diameter trunk.
Robert Weatherill,
Advanced Tree Care
performed an aerial
inspection of the canopy.
His report will provide an
assessment of the
condition of the tree's
canopy.
Lower trunk and root
collar
The lower trunk appeared
normal. I sounded this
area with a wood mallet
for decay and did not
detect any hollow areas. I
did not observe any decay
conks. A few small brown
mushrooms were found on
the shedding bark. This
fungus is likely
saprophytic.
You removed the soil
approximately 30" from the
base of the trunk between
the curb and sidewalk.
Twelve (12) buttress roots
(large woody roots) were
exposed. The roots
ranged in size from 4" to 25" in diameter, and were well distributed around the trunk (photo
2 and 3, next page). On the Easton Dr. side a section of raised asphalt about 5' by 8' was
removed. This revealed a solid mass of wood tissue 8' across. I could not determine if
this conformation was the result of the trunk growing over the old street, or roots that had
been ground down for street repairs and re-formed into the solid mass.
I examined each root and the root mass visually and sounded the roots with a wood mallet
for decay. I checked the condition of the underside of a few roots. All roots appeared
normal. Minor wounds were present on the top of a few roots near Easton Dr.
City staff authorized the use of the Resistograph® to validate the findings from the visual
tree assessment.

I probed four (4) areas of the trunk and four (4) locations on buttress roots (photos #2 and
3). The results are as follows.
■ Readings #1-4—N,S,E,W
at 18" above ground in
trunk; sound wood to 15",
depth of drill (Figure 1,
example of reading).
* Reading #5 (W between
#1 and 2) at ground level

wood to 15".
■ Reading #6 (S between #2
and 3) at ground level in
root mass, S of small
wound; sound wood to 4"
and decay from 4"-15".
■ Readina #7 (S between #2
ana �3) at grouna ievei in
root mass, N of small
wound in #6; sound wood
to 15".
■ Reading #8 (S between #3
and 4) at ground level in
buttress root, sound wood
to 15".
The readings for the trunk and
roots indicated sound wood
with one minor exception.
Reading #6 in the root mass,
near a small wound, found
decay, however a second
reading nearby indicated
soundwood.

Summary and Recommendations
An evaluation of the lower trunk and root collar of this mature blue gum showed these
areas appeared to be sound, with one minor exception. Decay was found in the root mass
on the south (reading #6). However, reading #7, just north of #6 showed sound wood to
depth of drill. I consider the small amount of decay found in #6 to be minor and not
unexpected in a tree of this size.
I assess the tree's potential to fail from the lower trunk or root collar as low. I recommend
the following.
Re -design of the damaged street near the tree should consider the following.
a. Excavation for street repair should be monitored by the City Arborist or a
Consulting Arborist. Some excavation by hand or air spade; may be required.
b. Locate new curb and gutter at least 6' from trunk and beyond the root mass.
c. Install tree protection fencing (TREE PROTECTION ZONE) at 1' back of curb prior
to construction. Use 6' high chain link fence on concrete blocks to protect the
lower trunk and root collar from damage by debris and equipment. Fence
shall remain until all construction is completed.
d. No root greater then 3" in diameter shall be pruned without the approval of the
arborist. Root pruning of roots 3" and smaller shall be clean and square at
undamaged tissue.
e. Use as much of the existing base rock under the street as possible to avoid
disturbing the roots. Where possible raise the street grade within the dripline
by adding base rock and ramping over the root zone.
f. All demolition and construction within the dripline shall be done using the
smallest equipment possible. The arborist will identify where excavation and
grading by hand will be required. The equipment shall operate so that it pulls
the asphalt away from the tree and parallel to the direction of root growth.
g. Do not remove the existing curb where the trunk has grown over it.
2. Monitor the tree for the presence of decay conks and mushrooms. During the spring
inspect trees for Ganoderma conks on the lower trunk and buttress roots. Conks are
directly attached to tree, reddish brown above and white below. In November and
December, following the first rains, inspect for sulfur fungus (Laetiporus gilbertsonir).
The bright, yellow conk appears annually and is often found on pruning wounds,
wounds and lower trunk. In late December and early January each year inspect for
Armillaria mushrooms at the base of tree. The mushrooms are brown to honey color
3. Following storms inspect the tree for cracks in the soil and/or increased lean that may
have developed under strong winds.
If you have any questions regarding my observations or recommendations, please feel
free to contact me.

An assessment
Of the health and condition of the canopy. 4/24/07
Genus and Species: Eucalytpus globulus more commonly known as a blue gum.
Size: DBH (Diameter at Standard Height) approximately 85.0 inches; canopy spread
60 feet by 60 feet; height approximately 140 feet; Live Crown Ratio 50%
Location: The tree is located in an easement at the front of Easton Branch Library at the
corner of Easton Drive and Cabrillo Avenue, Burlingame and can be seen in Photo. 1.

P. O. Box 5326 Redwood City, CA 94063 April 24" 2007
Condition: The trunk has a diameter of 82.5 inches at 54 inches above ground level
and splits into 3 smaller trunks at approximately 18 feet above ground level; one of these
trunks then separates again into 2 smaller trunks. These 4 trunks form the main spars of
the tree. The trunk attachments appear strong with no signs of decay or weakness such as
included bark.
e
Photo 2: Attachments of the 4 main trunks
Three of the trunks were previously cabled at approximately 65 feet above ground level.
The trunks at this height range from 30.0 inches to 35.0 inches in diameter. The cabling
system is clearly not to ANSI Standards ANSI A300 (Part 3) - 2000 has failed and is
hanging loose. The cabling system can be seen in Photo.3.

Photo. 3: Failed cabling system
The live canopy is thick and healthy and begins at approximately 80 feet above ground
level. At approximately 80 feet above ground level, there are several large pruning cuts
where large spars have been removed. One of these cuts can be seen in Photos. 4 and 5. It
can be seen that there is significant decay to a vertical depth of approximately 6 inches
after which the wood appears to be quite sound. The stems adjacent to this decay appear
to be very strongly attached.

Again at approximately 120 feet above ground level there are signs of decay from
previous pruning cuts. Many of these cuts have callused over as can be seen in Photo 7.
There is one or two with visible decay as seen in Photo. 6.
Photo. 6: Decay at 120 feet above ground level
The decay in the center of the trunk extends down approximately 3 inches before
reaching sound wood. At the surface of the trunk the decay extends further down its
length. There are several large cuts as shown in Photo. 6 over the Library side of the tree.
The growth adjacent to these cuts is predominantly epicormic growth from latent buds.
The canopy above 120 feet appears to be healthy with good branch unions. This can be
seen in photographs on the following pages. There are no visible cavities on the scaffold
limbs or trunk. Throughout the entire canopy are scars from climbing gaffs.

Summary: The canopy is thick and healthy. It has been well maintained in the past.
There is some decay throughout the canopy from previous pruning cuts which is actively
callusing over. The cabling system has failed but should not be removed. The main
scaffold limbs appear to have strong well formed attachments. Some of the growth higher
up in the canopy has emanated from epicormic growth and latent buds. Consequently, it
must be assumed that these branches are weakly attached to their parent limbs.
Recommendations: The tree should be regularly inspected and maintained.
Maintenance should involve replacement of the failed cabling system to ANSI
Standards ANSI A300 (Part 3) — 2000. Pruning should be carried out at regular
intervals or as deemed necessary by a Certified Arborist. Pruning should include
both thinning and end weight reduction.
