Date of Report: June 3, 2019
Introduction
The project proponent is planning to construct a new 55 lot residential subdivision on 10.06 acres
at 4130 Lincoln Ave. NE in Renton. The proponent has retained WFCI to:
Evaluate and inventory all trees on the site pursuant to the requirements of the City of
Renton Tree Protection Ordinance.
Make recommendations for retention of significant trees, along with required protection
and cultural measures.
Observations
Methodology
WFCI has evaluated trees 6 inches diameter at breast height (DBH) and larger in the proposed
project area, and assessed their potential to be incorporated into the new project.
The tree evaluation phase used methodology developed by Nelda Matheny and Dr. James Clark
in their 1998 publication Trees and Development: A Technical Guide to Preservation of Trees
during Land Development.

Site Description
The site was cleared many years ago and portions were replanted. The foundation of a former
residence is evident in the western portion of the northern parcel. The three houses that are
present in the project area were built in the late 1980’s. There is a wetland on the western edge
or the project area and a small stream in the northeast corner. The site slopes mostly to the west
at about 10%. It is bordered by Lincoln Ave. NE to the northwest, undeveloped forest land to
the east and northeast and residential parcels on all other sides.
Soils Description
There are three major soil types in the project area: the Alderwood gravelly sandy loam, the
Everett very gravelly sandy loam, and the Ragnar-Indianola association.
AgD, AgC – Alderwood gravelly sandy loam – 34%
RdE, RdC - Ragnar-Indianola Association – 61%
EvC - Everett very gravelly sandy loam – 5%
DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08
Canopy – Tree Protection Plan
Washington Forestry Consultants, Inc. Page 3
The Alderwood gravelly sandy loam is a moderately deep, moderately well drained soil found on
glacial till plains. It is formed in ablation till overlying basal till. A weakly cemented hardpan is
at a depth of 20 to 40 inches. Permeability is moderately rapid above the hardpan and very slow
in the pan. Available water capacity is low. The effective rooting depth for trees is 20-40
inches. A perched seasonal high water table is at a depth of 18-36 inches from November to
March. The potential for windthrow of trees is moderate under normal conditions. New trees
require irrigation for establishment.
In areas where grading brings the Alderwood hardpan nearer to the surface, the hardpan
must be fractured under new trees to provide soil volume for root development and to
improve drainage around the tree.
The Ragnar-Indianola association is primarily a loamy fine sand. It is a very deep, somewhat
excessively drained soil. It is formed in sandy glacial outwash and glacial drift on broad
uplands. Permeability is rapid. The available water capacity for plants is mostly low. The
effective rooting depth for trees is 60 inches or more. The potential for windthrow of trees is low
under normal conditions.
Everett very gravelly sandy loam, a very deep, somewhat excessively drained soil found on
terraces and outwash plains. It formed in glacial outwash. Permeability i s rapid. Plant available
water capacity is low. The effective rooting depth is 60 inches or more and the hazard of runoff
and erosion is slight. The potential for windthrow of trees is slight under normal conditions.
Seedling mortality is severe and new trees require irrigation to establish.
Existing Tree Conditions
There are a total of 323 significant trees in the project area outside of wetland areas and their
buffers. Tree conditions on the site range from ‘Dead’ to ‘Good,’ with most trees described as
being in ‘Fair’ condition. The size of significant trees ranges from 6 inches to 46 inches in
diameter at breast height (DBH). Tree species include Douglas-fir (Pseudotsuga menziesii),
western redcedar (Thuja plicata), black cottonwood (Populus trichocarpa), wild cherry (Prunus
avium), red alder (Alnus rubra), hawthorn (Crataegus laevigata), Alaska yellow-cedar
(Xanthocyparis nootkatensis), Siberian elm (Ulmus pumila), Norway spruce (Picea abies), grand
fir (Abies grandis), western white pine (Pinus monticola), ponderosa pine (Pinus ponderosa),
arborvitae (Thuja occidentalis), bitter cherry (Prunus emarginata), hybrid plane (Platanus x.
acerifolia), Scouler’s willow, and European mountain-ash (Sorbus aucuparia).

Discussion
Potential for Tree Retention
The site plan indicates that an area in the southeast portion of the project area that will be
designated as a ‘Green Space.’ This area contains a mixed stand of Douglas-fir and bigleaf
maple that is typical of project area. However, many of the multi-stemmed maples in this area
are unhealthy and otherwise unsuitable for retention near targets. Of the 66 significant trees in
this area, sixteen (16) of these trees are in ‘Fair’ condition or better and suitable for retention.
The remaining 50 trees in this area are in ‘poor’ or worse condition and will need to be removed
during land clearing.
Two additional trees (Tree #9319 and #9321) can be retained near the northern boundary of the
project area. The locations of these tree retention areas are illustrated on the site plan in
Attachment 2.
Tree Density Calculations
Title 4-4-130 of the Renton Municipal Code calls for 30% of all healthy significant trees in
buildable areas to be retained on the project, or where the required number cannot be retained,
replacement trees are to be planted. The following is a summary of the required and planned tree
retention as based on the currently proposed plan:
Total Number of Significant Trees on Site 377 trees
Trees Excluded from Retention Calculation:
Trees that are Dead, Diseased, or Dangerous <85 trees>
Trees in Proposed Public Streets <11 trees>
Trees in Critical Areas and Buffers <47 trees>
Number of Healthy, Significant Trees in Buildable Area: 234 trees
Required Tree Retention:
30% of healthy significant trees in buildable area: 70 trees
Planned Tree Retention <19 trees>
Shortfall of Retention under the Minimum Requirement 51 trees
Required number of replacement trees: 306 trees
There are 234 healthy significant trees in the buildable area of the site. At least 70 of these trees
need to be retained to meet the City of Renton Code. The proposed plan retains 19 trees outside
of the critical areas and buffers, a shortfall of 51 trees. When the required number of trees
DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08
Canopy – Tree Protection Plan
Washington Forestry Consultants, Inc. Page 6
cannot be retained, 12 caliper-inches of replacement trees must be replanted for each tree
removed in excess of this minimum requirement. All broadleaved replacement trees shall be 2
in. caliper and conifers shall be at least 6 ft. tall at the time of planting. A total of 306 trees
( 51∗12
2 ) will be required to replace the 51-tree shortfall outlined in this plan.
Up to 50% of the replacement trees (153 trees) may be planted on lots. The remaining 153 trees
can be planted in park and green space tracts. We recommend planting Douglas-fir in open areas
and western redcedar in areas with partial shade. Trees in the willow family (Salicaceae), and
the alder (Alnus), and plane tree (Platanus) genera may not be used to fulfill the tree replacement
requirement. The projected cost of the 312 replacement trees is $53,550. A fee in lieu of tree
planting, the cost of which can be determined by the City of Renton can also substitute for tree
replacement if replanting on-site is not feasible.
Recommendations
Tree Protection Measures
Trees to be saved must be protected during construction by a wooden, temporary chain-link
fence (Attachment 7), located at the edge of the root protection zone (RPZ). The RPZ shall be
the dripline of the stand of trees, or the limits of construction of the tree tract. Placards shall be
placed on the fencing every 50 feet indicating the words, "NO TRESPASSING - Protected
Trees". The individual tree RPZ is the dripline (6 feet minimum), unless otherwise delineated by
WFCI in the field and described in the attached tree list (Attachment 3).
Tree protection fences should be placed around the edge of the root protection zone (RPZ). The
fence should be erected after logging but prior to the start of clearing. The fences should be
maintained until the start of the landscape installation.
There should be no equipment activity (including rototilling) within the root protection zone. No
irrigation lines, trenches, or other utilities should be installed within the RPZ. Cuts or fills
should impact no more than 20% of a tree’s root system. If topsoil is added to the root zone of a
protected tree, the depth should not exceed 2 inches of a sandy loam or loamy fine sand topsoil
and should not cover more than 20% of the root system.
If roots are encountered outside the RPZ during construction, they should be cut cleanly with a
saw and covered immediately with moist soil. Noxious vegetation within the root protection
zone should be removed by hand. If a proposed save tree must be impact ed by grading or fills
more than allowed for by WFCI in the tree list, then the tree should be re-evaluated by WFCI to
determine if the tree can be saved with mitigating measures, or if the tree should be removed.
Pruning and Thinning
All individual trees to be saved near or within developed areas should have their crowns raised to
provide a minimum of 8 feet of ground clearance over sidewalks and landscape areas, 15 feet
over parking lots or streets, and at least 10 feet of building clearance.
DocuSign Envelope ID: C2073BA0-CA13-4596-8BE6-FB745ABA8D08
Canopy – Tree Protection Plan
Washington Forestry Consultants, Inc. Page 7
All pruning should be done according to the ANSI A300 standards for proper pruning, and be
completed by an International Society of Arboriculture Certified Arborist®, or be supervised by a
Certified Arborist®.
Hazard Tree Inspection
At least one tree (Tree #9014) was found to be hazardous during the tree evaluation. The tree is
a black cottonwood with a DBH of 19 inches. It is at a ‘high’ risk of failing and impacting
traffic on Lincoln Ave. NE due to a stem defect and some stem decay. It currently grows in a
wetland area near other cottonwoods and should be removed immediately.
Photo 2. Black cottonwood hazard tree (#9014) leaning over Lincoln Ave. NE.
A second inspection of the save trees should occur after the completion of grading to determine
if any trees were damaged during grading activity.

Conclusions and Timeline for Activity
1. 19 significant trees are proposed to be retained in tree tracts within the site (outside of critical
areas and their buffers). This falls short of the 30% tree minimum retention requirement by
51 trees.
2. The final, approved tree protection plan map should be included in the construction drawings
for bid and construction of the project and should be labeled as such.
3. Stake and heavily flag the clearing limits.
4. Contact WFCI to attend pre-job conference and discuss tree protection issues with
contractors. WFCI can verify all trees to be saved and/or removed are adequately marked for
retention.
5. Complete logging. Complete necessary hazard tree removals and invasive plant removals
from the tree protection areas. No equipment should enter the tree protection areas during
logging.
6. Contact WFCI to inspect the tree tracts after logging, but prior to land clearing to identify
any additional hazard trees that should be removed.
7. Install tree protection fences along the 'limits of construction'. The fences should be located
at the limits of construction or at the dripline of the save tree or as otherwise specified by
WFCI. Maintain fences throughout construction.
8. Complete clearing of the project.
9. Do not excavate stumps within 10’ of trees to be saved. These should be individually
evaluated by WFCI to determine the method of removal.
10. Complete all necessary pruning on save trees or stand edges to provide at least 8’ of ground
clearance near sidewalks and trails, and 15’ above all driveways or access roads.
11. Complete grading and construction of the project.
12. Contact WFCI to final inspect the tree protection areas after grading.
13. All save trees within reach of targets should be inspected annually for 2 years by a qualified
professional forester retained by the homeowners association, and bi-annually thereafter.
The purpose of these inspections is to identify trees that develop problems due to changing
micro-site conditions and to prescribe cultural care or removal.
Summary
The City of Renton Municipal Code calls for 30% of the significant trees be retained on the
buildable area of the site or mitigated for. Based on the current site plan, 19 existing trees in 2
tracts will be retained. This falls short of the minimum 30% requirement by 51 trees. Therefore,
306 replacement trees are required.
This tree protection plan coupled with the 47 trees growing in the wetlands and buffers, and the
healthy red alders and black cottonwoods that exist but were not counted, will help to preserve
the forested character of the area. As the street trees and landscape trees fill in the buildable area
over time, Canopy will be a very well-treed residential community.

ABBRV. ACTIVITY DESCRIPTION
CC Crown
Cleaning
Pruning of dead, dying, diseased, damaged, or defective branches over 1/2 inch in
diameter –includes removal of dead tops
CT Crown
Thinning
Pruning of branches described in crown cleaning, plus thinning of up to 20% of the live
branches over ½ inch diameter. Branch should be 1/3 to ½ the diameter of the lateral
branch. Thinning should be well distributed throughout crown of tree, and should
release healthy, long-term branches.
RC Crown
Reduction
Reduction of the crown of a tree by pruning to lateral branches. Generally used to
remove declining branches or to lighten end weight on long branches.
CR Crown
Raising
Pruning of lower branches to remove deadwood or to provide ground or building
clearances.
RMV Remove Remove tree due to decline or hazardous conditions that cannot be mitigated by
pruning.
RS Remove
Sprouts
Remove basal sprouts from stem of tree.
Rep Replace Tree is small – is in decline or dead. Replace with suitable tree species.
HT Hazard Tree Tree is hazardous and cannot be mitigated by pruning. Recommendation is to remove
tree.
None No Work No work necessary at this time.

Attachment 5. Description of Tree Evaluation Methodology
The evaluation of the tree condition on this site included the visual assessment of:
1. Live-crown ratio,
2. Lateral and terminal branch growth rates,
3. Presence of dieback in minor and major scaffold branches and twigs,
4. Foliage color,
5. Stem soundness and other structural defects,
6. Visual root collar examination,
7. Presence of insect or disease problems.
8. Windfirmness if tree removal will expose this tree to failure.
In cases where signs of internal defect or disease were suspected, a core sample was taken to
look for stain, decay, and diameter growth rates. Also, root collars were exposed to look for the
presence of root disease.
In all cases, the overall appearance of the tree was considered relative to its ability to add value
to either an individual lot or the entire subdivision. Also, the scale of the tree and its proximity
to both proposed and existing houses was considered.
Lastly, the potential for incorporation into the project design is evaluated, as well as potential site
plan modifications that may allow otherwise removed tree(s) to be both saved and protected in
the development.
Trees that are preserved in a development must be carefully selected to make sure that they can
survive construction impacts, adapt to a new environment, and perform well in the landscape.
Healthy, vigorous trees are better able to tolerate impacts such as root injury, changes in soils
moisture regimes, and soil compaction than are low vigor trees.
Structural characteristics are also important in assessing suitability. Trees with significant decay
and other structural defects that cannot be treated are likely to fail. Such trees should not be
preserved in areas where damage to people or property could occur.
Trees that have developed in a forest stand are adapted to the close, dense conditions found in
such stands. When surrounding trees are removed during clearing and grading, the remaining
trees are exposed to extremes in wind, temperature, solar radiation, which causes sunscald, and
other influences. Young, vigorous trees with well-developed crowns are best able to adapt to
these changing site conditions.

Attachment 6. Glossary of Forestry and Arboricultural Terminology
DBH: Diameter at Breast Height (measured 4.5 ft. above the ground line on the high side of the
tree).
Caliper: In Issaquah - Caliper is referring to diameter measurement at DBH.
Live Crown Ratio: Ratio of live foliage on the stem of the tree. Example: A 100’ tall tree with
40 feet of live crown would have a 40% live crown ratio. Conifers with less than 30%
live crown ratio are generally not considered to be long-term trees in forestry.
Crown: Portion of a trees stem covered by live foliage.
Crown Position: Position of the crown with respect to other trees in the stand.
Dominant Crown Position: Receives light from above and from the sides.
Codominant Crown Position: Receives light from above and some from the sides.
Intermediate Crown Position: Receives little light from above and none from the sides. Trees
tend to be slender with poor live crown ratios.
Suppressed Crown Position: Receives no light from above and none from the sides. Trees
tend to be slender with poor live crown ratios.

warranty or guarantee, expressed or implied, that problems or deficiencies of the tree or other plant or
property in question may not arise in the future.
Note: Even healthy trees can fail under normal or storm conditions. The only way to eliminate all risk is to remove
all trees within reach of all targets. Annual inspections by an ISA Certified Arborist or Certified Fore ster will
reduce the potential of tree failures. It is impossible to predict with certainty that a tree will stand or f ail, or the
timing of the failure. It is considered an ‘Act of God’ when a tree fails, unless it is directly felled or pushed over by
man’s actions.
