Assignment
It was our assignment to physically inspect trees in the survey area based on a topographic map
provided by the client. We were to map, tag and compile data for each tree and write an
inventory/tree survey report documenting our observations.
Summary
This survey provides a numbered map and complete and detailed information for each tree
surveyed. There are one hundred sixty-two trees included in this report. Two of the trees are
protected trees under the City of South San Francisco’s tree protection ordinance. Nineteen
unprotected trees are recommended for removal based on health and structure ratings.
Discussion
All the trees surveyed were examined and then rated based on their individual health and
structure according to the table below. For example, a tree may be rated “good” under the
health column for excellent/vigorous appearance and growth, while the same tree may be
rated “fair/poor” in the structure column if structural mitigation is needed. More complete
descriptions of how health and structure are rated can be found under the “Methods” section
of this report. The complete list of trees and all relevant information, including their health and
structure ratings, their “protected/significant” status, and a map with recommendations for
their care can be found in the data sheet that accompanies this report.

Poor dead or near dead hazard

Methods
The trunks of the trees are measured using an arborist’s diameter tape at 54” above soil grade.
In cases where the main trunk divides below 54”, the tree is measured (per the City of South
San Francisco’s tree ordinance) at the point where the trunks divide. In these cases, the height
of that measurement is given in the note’s column on the attached data sheet. The canopy
height and spread are estimated using visual references only.
The condition of each tree is assessed by visual observation only from a standing position
without climbing or using aerial equipment. No invasive equipment is used. Consequently, it is
possible that individual tree(s) may have internal (or underground) health problems or
structural defects, which are not detectable by visual inspection. In cases where it is thought
further investigation is warranted, a “full tree risk assessment” is recommended. This
assessment may be inclusive of drilling or using sonar equipment to detect internal decay and
include climbing or the use of aerial equipment to assess higher portions of the tree.
The health of an individual tree is rated based on leaf color and size, canopy density, new shoot
growth and the absence or presence of pests or disease.
Individual tree structure is rated based on the growth pattern of the tree (including whether it
is leaning); the presence or absence of poor limb attachments (such as co-dominant leaders);
the length and weight of limbs and the extent and location of apparent decay. For each tree, a
structural rating of fair or above indicates that the structure can be maintained with routine
pruning such as removing dead branches and reducing end weight as the tree grows. A
fair/poor rating indicates that the tree has significant structural weaknesses and corrective
action is warranted. The notes section for that tree will then recommend a strategy/technique
to improve the structure or mitigate structural stresses. A poor structural rating indicates that
the tree or portions of the tree are likely to fail and that there is little that can constructively be
done about the problem other than removal of the tree or large portions of the tree. Very large
trees that are rated Fair/Poor for structure AND that are near structures or in an area
frequently traveled by cars or people, receive an additional **CONSIDER REMOVAL” notation
under recommendations. This is included because structural mitigation techniques do not
guarantee against structural failure, especially in very large trees. Property owners may or may
not choose to remove this type of tree but should be aware that if a very large tree experiences
a major structural failure, the danger to nearby people or property is significant.
Survey Area Observations
The property is in the industrial section of South San Francisco. The surveyed area is rectangular
with curvatures on South Maple and South linden Ave. The property is occupied and flat.

Tree Health on This Property
Generally, the health of the trees in the survey area range from fair/good to poor. The property
is occupied until the construction phase starts. Individual issues and recommendations for each
tree are listed under the “Notes” column on the accompanying data sheet.
Tree Structure on This Property
Ideally, trees are pruned for structure when young and are properly mainained to reduce end-
weight as they grow. This practice prevents excessively long, lateral branches that are prone to
breaking off due to weight or wind. As mentioned above the property is occupied unitl the
contruction phase starts. The structure rating on the trees in the surveyed area range from fair
to poor ratings.

Risks to Trees by Construction
Besides the above-mentioned health and structure-related issues, the trees at this site could be
at risk of damage by construction or construction procedures that are common to most
construction sites. These procedures may include the dumping or the stockpiling of materials
over root systems; the trenching across the root zones for utilities or for landscape irrigation; or
the routing of construction traffic across the root system resulting in soil compaction and root
dieback. It is therefore essential that Tree Protection Fencing be used as per the Architect’s
drawings. In constructing underground utilities, it is essential that the location of trenches be
done outside the drip lines of trees except where approved by the Arborist.
General Tree Protection Plan
Protective fencing is required to be provided during the construction period to protect trees to
be preserved. This fencing must protect a sufficient portion of the root zone to be effective.
Fencing is recommended to be located 8 to 10 X the diameter at breast height (DBH) in all
directions from the tree. DBH for each tree is shown in the attached data table. The minimum
recommendation for tree protection fencing location is 6 X the DBH, where a larger distance is
not possible. There are areas where we will amend this distance based upon tree condition and
proposed construction. In my experience, the protective fencing must:
a. Consist of chain link fencing and having a minimum height of 6 feet.
b. Be mounted on steel posts driven approximately 2 feet into the soil.
c. Fencing posts must be located a maximum of 10 feet on center.
d. Protective fencing must be installed prior to the arrival of materials, vehicles, or
equipment.
e. Protective fencing must not be moved, even temporarily, and must remain in place
until all construction is completed, unless approved be a certified arborist.
f. Tree Protection Signage shall be mounted to all individual tree protection fences.
Based on the existing development and the condition and location of trees present on site, the
following is recommended:
1. The Project Arborists is Michael Young (650) 321-0202. A Project Arborist should
supervise any excavation activities within the tree protection zone of these trees.
2. Any roots exposed during construction activities that are larger than 2 inches in
diameter should not be cut or damaged until the project Arborist has an opportunity to
assess the impact that removing these roots could have on the trees.
3. The area under the drip line of trees should be thoroughly irrigated to a soil depth of
18” every 3-4 weeks during the dry months.
4. Mulch should cover all bare soils within the tree protection fencing. This material must
be 6-8 inches in depth after spreading, which must be done by hand. Course wood chips
are preferred because they are organic and degrade naturally over time.
5. Loose soil and mulch must not be allowed to slide down slope to cover the root zones or
the root collars of protected trees.
5
6. There must be no grading, trenching, or surface scraping inside the driplines of
protected trees, unless specifically approved by a Certified Arborist. For trenching, this
means:
a. Trenches for any underground utilities (gas, electricity, water, phone, TV cable,
etc.) must be located outside the driplines of protected trees, unless approved
by a Certified Arborist. Alternative methods of installation may be suggested.
b. Landscape irrigation trenches must be located a minimum distance of 10 times
the trunk diameter from the trunks of protected trees unless otherwise noted
and approved by the Arborist.
7. Materials must not be stored, stockpiled, dumped, or buried inside the driplines of
protected trees.
8. Excavated soil must not be piled or dumped, even temporarily, inside the driplines of
protected trees.
9. Landscape materials (cobbles, decorative bark, stones, fencing, etc.) must not be
installed directly in contact with the bark of trees because of the risk of serious disease
infection.
10. Landscape irrigation systems must be designed to avoid water striking the trunks of
trees, especially oak trees.
11. Any pruning must be done by a Company with an Arborist Certified by the ISA
(International Society of Arboriculture) and according to ISA, Western Chapter
Standards, 1998.
12. Any plants that are planted inside the driplines of oak trees must be of species that are
compatible with the environmental and cultural requirements of oaks trees. A
publication detailing plants compatible with California native oaks can be obtained from
The California Oak Foundation’s 1991 publication “Compatible Plants Under & Around
Oaks” details plants compatible with California native oaks and is currently available
online at: http://californiaoaks.org/wp-
