Introduction
The project proponent is planning to construct a new 5 lot short plat on one parcel totaling 1.10-acres at 3601 Lincoln Avenue 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 4-4-130 Tree Retention and Land Clearing Regulations.
•Make recommendations for retention of significant trees, along with required protectionand cultural measures.
•Complete the City of Renton Tree Retention and Credit Worksheet.
Observations
Methodology
WFCI has evaluated all trees with a caliper of at least 6" diameter at breast height (DBH), except
alder or cottonwood trees, which qualify as significant trees with a caliper of 8" or greater. To be a significant tree, it must have a condition rating of Fair or better. Trees rated as Poor, Very Poor, or Dead or are defective, diseased and/or in decline and are not long-term trees and are not considered to be significant trees. All off-site trees with driplines or root protection zones (RPZ’s) encroaching the site were assessed as well.
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 project site consists of one 1.10-acre parcel, #3345700230. A single-family home and
associated outbuildings are on the site. Most of the parcel is gently sloping to the west with very steep slopes on the western edge. There is a 0.23-acre steep slope critical area in this part of the site. The site is bordered by single-family homes to the north, south, and west, and Lincoln Avenue to the east.
Soils Description According to the USDA Natural Resource Conservation Service soil survey the three soil types in the project area are variants of the Alderwood gravelly sandy loam, 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. Effective rooting depth 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 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.

Existing Tree Conditions
There is one forest cover type on the project area for the purpose of description. The aerial photo
of the project, with tree locations, is shown in Attachment 1.
Type I. -- This cover type includes the entire project site. There are a total of 22 trees on the
parcel. There are introduced trees planted around the home and naturally seeded trees throughout the site. The size of significant trees ranges from 6 inches to 41 inches in diameter at breast height (DBH). Tree species include bigleaf maple (Acer macrophyllum), giant sequoia (Sequoiadendron giganteum), noble fir (Abies procera), smoke tree (Cotinus coggygria), weeping willow (Salix
babylonica), and western hemlock (Tsuga heterophylla).
Tree conditions on the site range from ‘Poor’ to ‘Good,’ with 91% being rated in ‘Fair’ or better condition. Twenty of the 22 significant trees could be potentially retained on this site when only tree health is considered. The remaining trees are multi-stemmed resprouted stumps that are not
quality formed trees to save. The eight Landmark sized tree on the project site are healthy. Sixteen
of the trees are located in a steep slope critical area. Table 1. Summary of trees on 3601 Lincoln Avenue NE Site.

Off-site Impacts
Seven off-site trees will be removed from the Lincoln Avenue and NE 36th Street rights-of-ways to construct this project. These trees are included in the tree list in Attachment 3. Discussion
Potential for Tree Retention The site plan shows no trees being retained on the buildable area of the site. The on-site trees are all under the footprints of improvements. This includes one Landmark sized weeping willow. Sixteen trees will be saved in the critical area.

Tree Density Calculations
Title 4-4-130H(a) of the Renton Municipal Code (RMC) requires 30% of the significant trees on the site to be retained. There are a total of 6 significant sized trees on the parcel outside the critical
area. After allowed tree deductions 4 healthy trees remain for calculating the 30% requirement. A
total of 1 significant tree will need to be retained in the project area to meet the requirement. Total # of Healthy Significant Trees: 20 Trees # of High Risk Significant Trees: 0 Trees
# of Trees in Steep Slope Critical Area: 16 Trees # of Significant Trees After Deductions: 4 Trees # of Significant Trees Required to be Saved
(30% of 4 Trees): 1 Tree
# of Significant Trees Planned to be Saved 0 Trees Shortfall of Significant Tree Requirement 1 Tree
Additionally, RMC4-4-130H(b) requires a minimum tree credit density of 30 tree credits per acre of net developable acreage. The following is a summary of the projected tree density requirements: Gross Site Acreage: 1.10 Acres
Proposed Rights-of-way Acreage: 0.32 Acres
Critical Area Acreage: 0.23 Acres Net Developable Acres: 0.55 Acres Required Tree Credit Density
(0.55 Acres x 30 Credits/Acre): 17 Tree Credits
Proposed Tree Retention: Developed Area (0 trees) 0.0 Tree Credits
Shortfall of Tree Credit Requirement: 17.0 Tree Credits
By retaining no trees in the buildable area of the site this plan falls short of the minimum significant tree retention requirement by 1 tree. Planned tree credit retention is less than the minimum tree credits by 17.0 credits. Seventeen tree credits will be required to replace the minimum credit
shortfall. When the required number of protected trees cannot be retained, replacement trees, with
at least a two-inch (2") caliper deciduous or an evergreen at least six feet (6') tall, shall be planted based on the tree credit value of each protected tree removed. 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.
All reasonable efforts have been taken to preserve trees utilizing the highest priority possible. The topography of the site requires significant grading to complete the project. The small lots, location
3601 Lincoln Avenue NE – Preliminary Tree Protection Plan
Washington Forestry Consultants, Inc. Page 6
of trees, grading, and required road improvements and utilities eliminates the number of trees that can be retained on the project.
Recommendations
Tree Protection Measures
All save trees, including off-site edge trees, must be protected during construction by a temporary
chain-link fence (Attachment 8). 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). If approved, the silt-fence could double as the tree protection fence for
select off-site trees. 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 impacted 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
Pruning should be done to coincide with land clearing, to facilitate clean-up and while access to the trees is available (before construction). 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. Care will need to be taken to avoid trespassing when pruning offsite trees. This is best achieved by getting cooperation and permission from the tree owner. If no permission is obtained, then legally one cannot prune beyond the property line – ground to sky.
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®.

Conclusions and Timeline for Activity
1. No trees outside of the critical area are proposed to be retained on the site.
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.
5. Conduct 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. Before land clearing is complete, do all necessary pruning on save trees and off-site trees to provided new home clearances.
7. Contact WFCI to inspect the tree tracts after logging, but prior to land clearing to identify any additional hazard trees that should be removed. 8. 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.
9. Complete clearing of the project. 10. Do not excavate stumps within 10’ of trees to be saved. These should be individually evaluated by WFCI to determine the method of removal. 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 homeowner’s 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 1 of the healthy, significant trees and 17.0 tree credits
be retained on the site. Based on the current site plan no trees will be retained because all healthy, significant trees in the buildable area are under the footprint of proposed improvements. An additional 30 trees will be required to replace the 30% significant tree requirement and tree credit shortfall.

Attachment 6. 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 7. 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).
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.

It is considered an ‘Act of God’ when a tree fails, unless it is directly felled or pushed over by man’s actions.
