Assumptions & Limitations
Summary
None of the four trees assessed at this site qualify as an Exceptional Tree as defined in the
City of Seattle DPD Director's Rule 16-2008, either due to their size or to significant structural
defects and potential risk for failure. Two big leaf maples (Acer macrophyllum) and a common
apple (Malus sp.) have significant trunk defects and established decay. The fourth specimen is a
tree of heaven (Ailanthus altissima), which due to its invasive roots and brittle wood is an
undesirable species for urban plantings. All four trees are recommended for removal.
Introduction
I met with Michael Willis of Ankrom Moisan Architects, Inc. onsite on March 4, 2015 to
review the 4 trees to be assessed at the 1401 E. Madison property. The purpose of this assessment
was to determine if any of the trees meet the Exceptional Tree as defined in the City of Seattle
DPD Director's Rule 16-2008, tree condition, and if they would be impacted by the proposed work
on the site.

Photo 1. Tree #1, Common apple. Two main scaffold limbs are broken, there is established decay in the trunks, and the tree is mostly dead.
The trees are numbered and named on the Tree Inventory Site Plan. The Tree Evaluation
Matrix provides details including species, trunk diameter, drip line radius, condition, maintenance
recommendations, risk of failure, preservation values, and Exceptional status.
Findings and Recommendations
None of the four trees assessed at this site qualify as an Exceptional Tree as defined in the
City of Seattle DPD Director's Rule 16-2008. Due to the species and poor physical conditions,
none of these trees are appropriate candidates for protection and preservation with new
construction.
Tree #1 Common apple, Malus sp.
This tree is near dead. It is
heavily covered in English ivy and two
main leaders have failed in the past. It
overhangs the parking area. Fungal
fruiting bodies are visible 5-feet up the
trunk. There is a high risk of failure in
the trunks showing decay and the trunks
would likely impact the parking area if
they failed. Removal is recommended.

Photo 2. Tree #2, Big leaf maple. There are 7 upright and leaning trunks, with well established decay at the base of several of them.
Photo 3. Tree #2. Established decay at the base of two of the ivy covered trunks.
Tree #2 Big leaf maple, Acer macrophyllum.
This tree is growing on a steep
slope and is heavily covered in English
ivy. The base of the tree lays horizontal
near the top of the slope and is shown
just east of the property line on the site
survey. Seven large trunks are growing
vertically and angled toward the west and
north from the base of the trunk across
the property line.
It appears the multiple trunks may
have grown from the cut stump of a
fallen tree. Well established decay and
hollows are visible at the base of several
of the trunks. The top has broken out of
one of the trunks. Partial or entire trunk
failure would likely impact the parking
lot area.
Given the significant trunk
defects and decay with a moderate to
high likelihood of large trunk failure, this
specimen does not qualify as an
Exceptional tree. Removal is
recommended.

Photo 4. Tree #3, Big leaf maple. This canopy is one-sided from past clearance pruning.
Photo 5. Tree #3. There is extensive dead wood and decay in trunks on the north side of the tree.
Tree #3 Big leaf maple, Acer macrophyllum.
Eight trunks, some with included bark, originate near the base. These appear to be stump
sprouts grown from a previously cut tree. There is well established decay and dieback in several
trunks, and large dead branches in the canopy overhanging the parking area. The top has broken
out of one of the trunks. It has been pruned on one side for clearance with the building on the
adjacent property.
The weak structure of the tightly spaced trunks, along with the extensive dieback and decay
presents a high risk of future limb and/or trunk failure which could impact the parking area. It is
not a good candidate for retention with new construction. Removal is recommended.
Photo 6. Tree #3. There is extensive dead wood and decay near the base of trunks on the west side of the tree.

Photo 6. Tree #4, tree of heaven. This is an invasive and undesirable urban tree species.
Tree #4 Tree of heaven, Ailanthus altissima.
This species is considered invasive and is a
prohibited species for street tree planting in Seattle
due to its invasive roots, brittle wood, and tendency
to sucker. It is of low value for retention with new
construction.
Level 2 Basic Tree Risk Assessment
The methodology to evaluate these trees follows the process and criteria provided in the Tree Risk
Assessment Qualification (TRAQ) training. TRAQ was developed, and is administered, by the
International Society of Arboriculture (ISA) and follows the ISA's Best Management Practices - Tree Risk
Assessment publication.
The Level 2 Basic Tree Assessment is a detailed visual inspection of a tree and its surrounding site,
and a synthesis of the information collected. It requires that a tree risk assessor walk completely around the
tree, looking at the site, buttress roots, trunk, and branches. This basic assessment may include the use of
simple tools to gain additional information about the tree or defects. Defects found in a level 2 Basic Tree
Assessment may require a Level 3 assessment for further testing and analysis.
Tree condition is determined based on visual inspection of the above-ground portions of the trees. Of
particular concern is trunk soundness, tree structure, bud fullness and color, twig length, crown ratio,
density of leaves, evidence of disease-causing bacteria, fungi or virus, deadwood, and dead or broken
hanging limbs.
While no one can predict with absolute certainty which trees will fail and which trees will remain
healthy, by methodical process we can predict those most likely to fail by the conditions observed and take
appropriate action to reduce or eliminate the potential hazard. The time frame for this Level 2 assessment
considers expected conditions and issues over the next year. Because tree conditions change over time,
further assessment may be needed at future points in time.

DEFINITIONS AND NOTES:
(1) dbh = Diameter at breast height (measured 4.5 ft. above surface grade).
(2) Drip line radius = As defined in Seattle Municipal Code Chapter 25.11, the area around the base of a tree delineated by a vertical line
extending from the outer limit of a tree's branch tips down to the ground. Used to define the basic tree protection area.
(3) Vigor = Health based on size and color of leaf or needle and length of annual shoot growth. Good = Shoot growth, leaf size and leaf color are typical of the tree age and species. Fair = Shoot growth, leaf size, and leaf color are below average for the tree age and species. Some deadwood is evident in the crown.
Treatment may be required to foster improved future growth. Poor = Shoot growth, leaf size, and leaf color are highly stunted, and there is a significant amount of dead twigs and branches in the crown.
(4) Structure = Trunk and branch development and it's estimated susceptibility to failure.
Good = No significant defects evident in the trunk, scaffold limbs, and root flare area. Fair = Minor defects evident. Poor = Significant defects that could lead to future failure of main branches or the entire tree.
(5) Risk of Failure:
Based on a Level 2 Basic Tree Risk Assessment in accordance with the Tree Risk Assessment Qualification training and standards administered
by the International Society of Arboriculture. The time frame for this assessment is one year.
Low = Defect(s) not likely to lead to immanent failure. No further action is required at this time.
Moderate = Tree has established defects with failure being likely or very likely with minor consequences expected. These often have
"retain and monitor" status. Mitigation and other recommended measures may be indicated under "Maintenance Recommendations" in the
matrix.
High = Tree has significant defect(s), and failure is likely or very likely and the consequences are significant or severe. Recommended
mitigation measures and timing are provided under "Maintenance Recommendations" in the matrix.
Extreme = Tree failure is imminent with a high likelihood of hitting the target. This is an emergency situation where immediate action is
needed.

(6) Maintenance Recommendations Explanation Cable and/or Brace = Cabling and/or Bracing would decrease the potential risk of failure, but not eliminate the possibility. Create Wildlife Snag = Cut danger trees to a lower stable height to serve as wildlife snags, providing perching, nesting, and a source of food for birds and other wildlife. Crown Clean = Selective removal of one or more of the following items: dead, dying, diseased, weak branches, and epicormic shoots from a tree's crown.
Crown Raise = Selective removal of lower branches of the tree in order to provide clearance. Crown Reduction = Reduction in size or height of tree by pruning away height or width. Arborist must be knowledgeable of the ability of the species to sustain this type of pruning. Crown Restoration = Pruning to improve the structure, form, and appearance of trees that have been severely headed, vandalized, or storm damaged. Crown Thin = Selective removal of branches to increase light penetration, air movement, and reduce end weight. Monitor = These are trees of a particular species or condition that may be prone to more rapid decline than other trees. These trees should be inspected at least annually for changing conditions. Remove = The high to extreme risk of failure warrants that the tree shall be removed immediately.
PRUNING NOTE: Pruning shall be performed by an ISA Certified Arborist with proven knowledge and ability, using ANSI A300 Pruning Specifications. The actual work should be bid by companies qualified to do the work. (7) Preservation Value Explanation
LOW = Poor specimen MODERATE = Common species with minimal character. HIGH = Good character tree, save if possible. SPECIAL = Unique species, save if possible.
(8) Exceptional Designation = as defined by the City of Seattle Department of Planning and Development Director's Rule 16-2008.
(9) Comments and Defects::
Codominant trunks = Vertical stems of equal diameter, often with included bark and a weak point of attachment to the main trunk. Decline = Loss of vigor of the entire tree that is typically not reversible. End weight = Accumulation of dense growth at the end of a branch which can lead to structural weakness of the limb. Epicomic shoots = Stem growth originating from dormant buds beneath the bark, commonly in response to injury, stress, or pruning. Included bark = Branch junction where branch bark ridge and bark is imbedded between stems, creating high probability of failure. Live crown ratio = The ratio of the foliage canopy height to the total height of the tree. Trunk taper = Natural broadening in diameter at the base of the main trunk and large scaffold limbs associated with strong structure.

ASSUMPTIONS AND LIMITING CONDITIONS
Urban Forestry Services, Inc. 15119 McLean Rd.
Mount Vernon, Washington 98273
1. Limitations of this Assessment This Assessment is based on the circumstances and observations as they existed at the time of
the site inspection of the Client’s Property and the trees inspected by Urban Forestry Services, Inc. and upon information provided by the Client to Urban Forestry Services, Inc. The opinions in this Assessment are given based on observations made and using generally accepted professional judgment, however, because trees and plants are living organisms and subject to change, damage, and disease, the results, observations, recommendations, and analysis took place and no guarantee, warranty, representation, or opinion is offered or made by Urban Forestry Services, Inc. as to the length of the validity of the results, observations, recommendations, and analysis contained within this Assessment. As a result, the Client shall not rely upon this Assessment, save and except for representing the circumstances and observations, analysis, and recommendations that were made as at the date of such inspections. It is recommended that the trees discussed in this Assessment should be re-assessed periodically.
Urban Forestry Services, Inc. shall not be required to give testimony or to attend court by reason of this report unless subsequent contractual arrangements are made, including payment of an additional fee for such services as described in our fee schedule and contract of engagement. Sketches, diagrams, graphs, and photographs in this report, being intended as visual aids, are not necessarily to scale and should not be construed as engineering or architectural reports or surveys.
2. Reaction of Assessment The Assessment carried out was restricted to the Property. No assessment of any other trees or
plants has been undertaken by Urban Forestry Services, Inc. Urban Forestry Services, Inc. is not legally liable for any other trees or plants on the Property except those expressly discussed herein. The conclusions of this Assessment do not apply to any areas, trees, plants, or any other property not covered or referenced in this Assessment.
3. Professional Responsibility In carrying out this Assessment, Urban Forestry Services, Inc. and any Assessor appointed for
and on behalf of Urban Forestry Services, Inc. to perform and carry out the Assessment has exercised a reasonable standard of care, skill, and diligence as would be customarily and normally provided in carrying out this Assessment. The Assessment has been made using accepted arboricultural techniques. These include a visual examination of each tree for structural defects, scars, external indications of decay such as fungal fruiting bodies, evidence of insect attack, discolored foliage, the condition of any visible root structures, the degree and direction of lean (if any), the general condition of the tree(s) and the surrounding site, and the current or planned proximity of property and people. Except where specifically noted in the Assessment, none of the trees examined on the property were dissected, cored, probed, or climbed and detailed root crown examinations involving excavation were not undertaken.
While reasonable efforts have been made to ensure that the trees recommended for retention are healthy, no guarantees are offered, or implied, that these trees, or all parts of them will remain standing. It is professionally impossible to predict with absolute certainty the behavior of any single tree or group of trees, or all their component parts, in all given circumstances. Inevitably, a standing tree will always pose some risk. Most trees have the potential to fall, lean, or otherwise pose a danger to property and persons in the event of adverse weather conditions, and this risk can only be eliminated if the tree is removed.
