SE Renton, WA Prepared for: Barbara Yarington, Henley USA Prepared by: Washington Forestry Consultants, Inc. Original Report Date: October 23, 2014 Revised Report Date: August 16, 2017 (Replaces July 5, 2017 Report) Introduction The project proponent is planning to construct a new 96 lot subdivision on 21.66 acres at SE 18th Street in Renton, WA. 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. Black cottonwood and red alder were inventoried and numbered, but excluded from tree retention calculations. 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. Allura at Tiffany Park – Revised Tree Protection Plan Washington Forestry Consultants, Inc Page 2 Site Description The site was previously logged many years ago and was not replanted. The trees on the site are all naturally regenerated. Five small wetlands are located on the site. There are no structures located on the site. There are many trails throughout the site. Forest Inventory by Forest Cover Type There are two forest cover types for the purpose of description. Both types are natural stands. These stands were inventoried using variable area plots installed on a systematic grid across the site. This sample of the tree population will predict the total population of trees with a 95% level of confidence. The trees within the proposed tree tracts were 100% inventoried and evaluated. The location of the types is illustrated on the aerial photo in Attachment #1. Type I. -- Type I is the largest type of the site. The trees in this type are native species. The species found in this type include bigleaf maple (Acer macrophyllum), western hemlock (Tsuga heterophylla), western red cedar (Thuja plicata) and Douglas-fir (Pseudotsuga menziesii). There are a small number of other species intermixed. A total of 857 trees are projected to exist in the type, ranging in diameter from 6 to 36 inches DBH. Six hundred and thirty-two (642) of the trees were classified as sound, healthy, long-term trees in the dominant and co-dominant crown class. The other 215 trees are not long-term trees due to structural defects or poor health (dead, diseased, or hazardous). Table 1. Summary of Trees in Type I. Species DBH Range (in.)

A total of 467 trees ranging in diameter from 6 to 26 inches at DBH are projected to be in the type. The tree species found in this type include bigleaf maple, Douglas-fir, western hemlock and western red cedar. There are a small number of other species intermixed. Three hundred and thirteen (319) trees were classified as sound, healthy, long-term trees in the dominant and co- dominant crown class. The other 147 trees are not long-term trees due to poor health (dead, diseased, or hazardous). Table 2. Summary of Trees in Type II. Species DBH Range (in.)

Summary of All Trees on the Site There are a total of 1,324 trees on the site that range from 6 to 36 inches DBH. Of these 1,324 trees, there are 362 trees that are dead, dying, or diseased, leaving 961 that are considered to be healthy trees. Bigleaf maple is the predominant tree species making up 72% of the significant trees in the forest. Table 3. Summary of all Trees on the Site. Species DBH Range (in.)

Allura at Tiffany Park – Revised Tree Protection Plan Washington Forestry Consultants, Inc Page 4 Discussion Potential for Tree Retention The following table provides a summary of all potential tree tract areas on the site and whether the trees could be saved or removed in the project. There are 12 tracts (Tracts A, B, D, E, F, G, H, I, J, L, R and S) that have the potential to have trees retained on them. These are illustrated on the proposed site plan in Attachment #2. A summary of significant trees by tract, species, condition, and DBH class is provided in Table 4 below. A list of all individual trees is provided in Attachment #4. Table 4.

These new trees are smaller bigleaf maples that had grown into the 6” diameter class since the initial inventory. The inventory was done in the field and not from the surveyed map. A full list of all tract trees, including red alder and cottonwood, and save or removal recommendations for each tree, is provided in Appendix #4. Allura at Tiffany Park – Revised Tree Protection Plan Washington Forestry Consultants, Inc Page 5 A total of 17 significant trees were found in the tracts that should be removed because of poor health and/or structural defects. Fifty-two (52) trees will need to be removed because of grading (cuts or fills) for wall, utility, or street construction. The remaining 218 trees could be retained in the 12 tracts. This tree inventory was done after staking of the tree tracts. 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 Project Area 21.66 acres Critical Areas and Buffers <1.70 acres> Rights-of-ways <4.15 acres> uildable Area 15.81 acres Total Number of Significant Trees on Site 1,324 trees Trees Excluded from Retention Calculation: Trees that are Dead Diseased or Dangerous <363 trees> Trees in Proposed Public Streets <238 trees> Trees in Critical Areas and Buffers <72 trees> Trees on Private Easements <15 trees> Number of Healthy, Significant Trees in Buildable Area: 636 trees Required Tree Retention: 30% of healthy significant trees in buildable area: 191 trees Planned Tree Retention 218 trees Excess of Retention over the Minimum Requirement 27 trees Required number of replacement trees: 0 trees There are 636 healthy significant trees in the buildable area of the site. At least 191 of these trees need to be retained to meet the City of Renton Code. The proposed plan retains 218 trees outside of the critical areas and buffers, an excess of 27 trees Allura at Tiffany Park – Revised Tree Protection Plan Washington Forestry Consultants, Inc Page 6 Recommendations Tree Protection Measures Trees to be saved must be protected during construction by a six foot high chain link fence (Attachment #8), 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 #4). 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 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. 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®. Allura at Tiffany Park – Revised Tree Protection Plan Washington Forestry Consultants, Inc Page 7 Hazard Tree Inspection in the Wetlands and their Buffers A tree risk assessment was done on June 14, 2017 in the wetlands and their buffers. We found 5 trees that were dead or dying and require removal. All 5 trees would threaten targets within and on the perimeters of the project. The only potential mitigation for these trees was removal – pruning is not an option. Table 5. Summary of hazardous trees found in the wetlands and their buffers. Tree Number Species DBH (in) Condition Tract – Wetlands and their Buffers Primary Defect 1 Bigleaf Maple 17 Poor – top is dead and roots are exposed from natural erosion. B Dying and unstable 2 Black Cottonwood 26 Poor – Decay conks on the stem – stem is hollow; B Severe internal decay 3 Black Cottonwood 16 Dead K Dead 4 Black Cottonwood 18 Dead K Dead 5 Black Cottonwood 21 Dead K Dead Conclusions and Timeline for Activity 1. 218 significant trees are proposed to be retained in tree tracts within the site (outside of critical areas and their buffers). This exceeds the 191 tree minimum retention (30%) requirement by 27 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. Allura at Tiffany Park – Revised Tree Protection Plan Washington Forestry Consultants, Inc Page 8 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, 218 existing trees in 12 tracts will be retained. This exceeds the minimum 191 tree (30%) requirement by 27 trees. Therefore, no additional replacement trees are required. This tree protection plan coupled with 62 additional trees 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, Tiffany Park will be a very well-treed residential community. Please give me a call if you have further questions.

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. Allura at Tiffany Park – Revised Tree Protection Plan Washington Forestry Consultants, Inc Page 15 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. Allura at Tiffany Park – Revised Tree Protection Plan Washington Forestry Consultants, Inc Page 16 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). 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.

There is no 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 Forester will reduce the potential of tree failures. It is impossible to predict with certainty that a tree will stand or fail, 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.
