Tree Assessment Report – East Lake Sammamish Trail’s South B Segment

Page 1 American Forest Management, Inc. 9/27/2016

1. Summary An assessment of significant trees within the East Lake Sammamish Trail (ELST) South B Segment was conducted. The South B Segment goes from SE 33rd St to approximately 500’ south of Kokomo Drive. As defined in the Sammamish Municipal Code, significant trees are coniferous trees with a DBH (diameter at breast height, 4 ½’ above ground) of 8 inches or greater and deciduous trees with a DBH of 12 inches or greater. The assessment included (1) a general inventory of significant trees within the proposed clearing and grading limits and (2) a more detailed evaluation of significant trees just beyond the clearing and grading limits that may be adversely impacted by trail improvements. The King County right-of-way is typically 100 feet wide. Not every tree within the right-of-way was assessed. The trees to be included in the assessment were identified by a yellow laminated paper tree tag stapled on each tree by Parametrix. These tags were placed on the lower trunks of trees within approximately 40’ of the clearing and grading limits. Data for significant trees can be found in the attached tree summary table. Detailed evaluations were completed for 847 significant trees within the right-of-way. In addition, the 26 non-significant trees that were tagged were also assessed. Potential impacts were evaluated based on the project survey and 60-percent design plans provided by Parametrix. A recommendation was given based on anticipated impacts, current tree condition and tree species suitability for long-term retention. 254 significant trees exist within the proposed clearing and grading limits and are proposed for removal to install trail improvements. In addition, 19 trees outside of the clearing and grading limits are in poor condition and are recommended for removal to maintain risks at acceptable levels. Of the 273 trees proposed for removal, 40 trees meet the Sammamish Municipal Code definition of a heritage tree (22-inch or greater diameter) and 9 meet the criteria for a ‘Landmark’ tree (32-inch or greater diameter). Significant Tree data is summarized as follows.

Trees to be Saved 574 No action needed 529 Monitor – could still be affected by construction 45 Trees to be Removed 273 Within clearing and grading limits 254 Outside clearing and grading limits 19

TOTAL 847 Trees with a recommendation to monitor shall be periodically evaluated throughout the construction process. The objective is to save these trees if possible. Recommended clearance and abatement pruning shall be performed prior to construction to avoid unnecessary damage to trees to be retained. There are several trees in the monitor category that will need to be pruned to provide trail construction clearance. Trees requiring clearance pruning are identified in the Tree Summary Tables.

3. Assignment The assignment is a condition assessment of all tagged significant trees within the right-of-way of the ELST. The section of trail subject to this report starts at station 468+00 approximately 500’ south of Kokomo Drive to station 284+00 near SE 32nd Street, encompassing roughly 3.5 miles. The trees subject to this report are those within approximately 40’ of the current trail centerline. Tree locations are surveyed and the trees inclusive of this assessment were identified with a laminated yellow numbered placard Exhibit 61

prior to this assessment. The assignment does not include a condition and risk assessment of all of trees within the right-of-way for ELST.

4. Purpose and Use of Report The purpose of this report is to provide Parametrix with baseline data for trees within the trail corridor and those potentially affected by the planned improvements to ELST. This data will aid the client in determining which trees can be saved and which trees should be monitored.

5. Limits of Assignment The assignment is limited to the information gathered during the multiple site visits in April and May of 2016 and references noted in this report. No invasive methods were used to assess tree condition unless fully described in the “Analysis and Testing” section of this report. Information from published sources cited herein is assumed to be reliable. Impacts and the long-term viability of trees were judged by evaluating tree conditions and proposed improvements. No staking of improvements was done prior to the assessment, so the assessment is limited to interpretation of site plans. No final elevations are provided on site plans, which further limit the evaluation of the depth of cuts and fills adjacent to subject trees.

6. Site Description The assessment area consists of the right-of-way of ELST located between SE 33rd Street and a location approximately 500’ south of Kokomo Drive, limited by the assignment to those trees identified by the client. The trail is an old built-up railroad grade with often moderately to steeply sloping cut banks. Many trees have been planted in the ROW by adjacent owners. These are primarily coniferous species for screening purposes. Planted tree species are primarily comprised of Leyland cypress and Douglas-fir, with minor components of pine, spruce and other cypress varieties. The native forest cover found adjacent to the subject trail segment consists mainly of deciduous broadleaved trees, largely big leaf maple, red alder, willow, Oregon ash and black cottonwood.

7. Methodology Each tree in the assignment was visually examined for outward defects and indications of decline. Tree diameters (diameter at breast height, 4.5’ above ground level) were measured by tape or estimated. The tree heights were measured using a Spiegel Relaskop or estimated. Crown width in four cardinal directions was measured by tape or estimated. The tree assessment procedure involves the examination of many factors:

• The crown of the tree is examined for current vigor. This is comprised of inspecting the crown (foliage, buds and branches) for color, density, form, and annual shoot growth, limb dieback and disease. The percentage of live crown is estimated for coniferous species only and scored appropriately.

• The bole or main stem of the tree is inspected for decay, which includes cavities, wounds, fruiting bodies

of decay (conks or mushrooms), seams, insects, bleeding, callus development, broken or dead tops, structural defects and unnatural leans. Structural defects include crooks, forks with V-shaped crotches, multiple attachments, and excessive sweep.

• The root collar and roots are inspected for the presence of decay, insects and/or damage, as well as if

they have been injured, undermined or exposed, or original grade has been altered. Information for the trees subject to this report can be found on the attached Tree Condition Summary Table.

8. Observations/Discussion Beginning at Station 468 and working south Station 467 to 459 – Tree #8056 - #8092 This segment is primarily big leaf maple and black cottonwood trees. Most of the trees in this area are outside the C&G limits and can be successfully retained.

The black cottonwoods in the subject area range in condition. Most are mature. Common defects include forked trunks with included bark. The big leaf maples in the subject area are generally mature specimens with co-dominant stems and large, widespread crowns. Common defects observed were dead stems and co-dominant stems with included bark.

Monitor Trees Tree #8087 is a 12” DBH black cottonwood. This tree has noteworthy dieback in the upper crown. Tree #8080 is a Douglas-fir with two co-dominant stems. This tree has included bark at the point of stem attachments. It is also infected with a decay pathogen. The subject tree is 38’ from the trail edge. Station 464 to 459 – Tree #8093 - #8119 The subject area is primarily big leaf maple and black cottonwood trees. Common defects include forked trunks, leaning trunks, and branch failures. There is a row of non-significant Douglas-fir trees near station 461-00. This row of trees is within the fill line and will have to be removed. Between station 460 and 459 there is a Leyland cypress hedge in the C&G limits that will have to be removed.

Monitor Trees Tree #8108 is a big leaf maple adjacent to stream #0143L. This tree has a forked trunk, broken tops, and trunk decay (whiter rot). Tree #8117 is a big leaf maple with co-dominant stems and included bark at the point of attachment. There is decay at the point of branch attachment. Tree #8119 is a 19” black cottonwood over 20’ from the trail edge. The subject tree has a slight lean west towards the trail. Station 459 to 455 – Tree #8120 - #8140 The subject area is a mix of native and non-native species. Notable defects observed include leaning trunks, ivy covering lower trunks and co-dominant stems. There are non-significant trees on the west edge of the trail within the C&G limits for the majority of this segment. Trees #8131 - #8133 will be compromised by the proposed stairway and necessitate removal. Station 455 to 450 – Tree #8141 - #8167, #8169 The subject area has a few spread out clusters of trees. There are a few small wetlands and streams on both sides of the trail. The subject trees are primarily native species with a minor component of non-native tree species. Common defects include leaning trunks, co-dominant stems and trunk bleeding. Tree #8159 is a 21” DBH western red cedar. This tree is on the C&G line but far from the fill limit. This tree should be retained.

Monitor Trees Tree #8146 is a mature western hemlock with bleeding on the lower trunk, indicator of internal stem decay. Tree #8167 is a red alder with co-dominant stems. One trunk leans west towards the trail. This tree is adjacent to the C&G limits. The addition of parking area at station 450+50 will require the removal of trees #8163, #8165, 381666 and #8167. Station 450 to 445 – Tree #8168, #8170 - #8184 There are small wetlands and streams on the east side of the trail. There are few trees scattered throughout and a cluster of trees near station 445.

This segment has a variety of native and non-native species. Most are in close proximity to the trail and the majority are feasible for retention. Near stations 417 and 418, there are several trees on the west side of the trail that will be compromised by trail improvements, necessitating removal. Tree #8327 - #8338 are Leyland cypress trees east of the trail. These cypress trees are not within the fill limit and will easily be retained. Station 414 to 410 – Tree #8368 - #8375, #8388 - #8392 This segment has two wetlands and a variety of trees dispersed throughout. There is a Leyland cypress hedge at station 413 that is within the C&G limits and will have to be removed. Tree #8373 and #8374 are Douglas-fir trees within the C&G limits but near the edge. These will be retained if feasible, both are young specimens that may be able to tolerate the proposed impacts. Station 410 to 405 – Tree #8376 - #8387, #8393 - #8405, #8423 - #8427 This segment has a row of conifers on the west side and a wetland on the east side. All but two of the significant trees in this segment are viable for retention. Tree #8376 - #8385 and #8393 - #8395 are Douglas-fir trees, west of the trail and close to the C&G limits but viable for retention. Tree #8423 - #8427 are Oregon ash trees in the wetland east of the trail. These trees have a variety of defects including dead stems and poor structure. The Oregon ash trees are in fair condition and are all viable. There is a Leyland cypress hedge from station 408 to 406+50. Station 405 to 400 – Tree #8406 - #8423, #8435 - #8445 Between station 405 and 404 there are a row of primarily western red cedar trees. The majority of these are within the C&G limits and close to the fill line. Western red cedar trees are not tolerant of root disturbance, the majority of these trees will have to be removed. Large extents of this segment have non-significant arborvitae hedges west of the trail edge. These arborvitaes are within the fill limit and will have to be removed. Station 400 to 395 – Tree #8446 - #8494 This segment is mainly Douglas-fir trees and Leyland cypress trees. There is an arborvitae hedge west of the trail in the C&G limits between stations 397 and 396. These arborvitae trees will be need have to be removed. Tree #8494 is a mature willow tree inside the C&G limits. Removal is warranted. Station 395 to 390 – Tree #8495 - #8591 This segment comprises a mix of species, primarily planted. Tree #8496 - #8501 are Douglas-fir trees west of the trail, on the C&G line. These trees were planted too closely together and structural defects are common as a result. These trees are viable for retention. Tree #8502 - #8519 are Leyland cypress trees west of the trail. Poor trunk taper and trunk leans afflict many of these trees. This is the result of these trees being planted too closely together. In addition to structural defects, some of the trees have been impacted by construction on the west side. All of these are inside the C&G line and proposed for removal. Tree #8520 - #8528 are Leyland cypress trees near the C&G limits. This row of trees was also planted too closely together. All are considered to be in fair condition and should be saved if possible.

Station 330 to 325 – Tree #8755 - #8765 This segment is primarily non-native species. The species in order of abundance are Douglas-fir, Leyland cypress, Japanese white pine, honey locust and green ash. These have Common structural defects from being planted too closely together, forked trunks and topped trees. There’s a small arborvitae hedge between station 328 and 329. Station 325 to 320 – Tree #8766 - #8774 This segment has a few significant trees of mixed species close to the trail. Trees #8768 – #8771 are Douglas-fir trees on the C&G line. All four trees were topped and are in fair condition. These trees can be retained successfully and some pruning may be necessary. There are two big leaf maple trees, #8766 and #8767 in this segment. Both trees were topped, have significant decay and dieback. Both trees are in the C&G limits and will be removed.

Tree #8772 is a pacific madrone with a forked trunk and limb dieback. This tree is 12’ w of the trail edge. The subject tree is in fair condition and can be retained. Tree #8773 and #8774 are Leyland cypress trees. Both trees have multiple trunks, are in fair condition and can be retained. Station 320 to 315 – Tree #8775 - #8789 This segment is a mix of native and non-native tree species. There are few significant trees in this segment. There are three corkscrew willow trees, #8786 - #8788, in this segment. All three lean west towards the trail and have some amount of limb dieback. All three trees lean west towards the trail. Tree #8787 is a corkscrew willow that needs to be pruned back to reduce the risk. Currently tree #8787 poses a moderate risk but with pruning this tree risk could be reduced to low. There are three western red cedar trees, #8780 - #8782, west of the trail. All three are in good condition, are far from the trail and will be easily retained. There is an arborvitae hedge on the west side from approximately station 319 to 317. From approximately station 317 to 316 there is a laurel hedge on the west side. There is a laurel hedge east of the trail from approximately station 318 to 316. All of these non-significant trees are within the C&G limits and will have to be removed for trail construction. Monitor Tree #8778 and #8779 are Oregon ash trees east of the trail, outside of the C&G limit. Both trees are mature and have moderate crown dieback. Both trees. Tree #8778 has deadwood hanging over the trail and #8779 has low vigor. Section 315 to 310 – Tree #8791 - #8801 This segment is primarily native species. The most common species is Douglas-fir followed by big leaf maple, bitter cherry and red alder. The majority of these trees will be retained. There are seven Douglas-fir trees in the segment. Some of these trees have thin crowns, forked trunks or ivy covering the lower tree trunks. All of the Douglas-fir trees are in fair to good condition. A few are in the C&G limits and will have to be removed for the trail construction. Section 310 to 305 – Tree #8808 - #8811, #8816 - #8824 This segment has a variety of species, widely spaced. Only one significant tree, an 8” DBH Leyland cypress, in this segment will be removed for the trail construction. The Douglas-fir trees, #8811, #8818 - #8823, are semi-mature. Some are on the top of a steep slope. All are at least 10’ from the trail edge. Defects include limb dieback, broken tops and leaning trunks. There are two pacific madrones, #8816 and #8817. Both trees have co-dominant stems, moderate crown dieback and are located on steep slopes. These trees will be impacted by trail construction but retention is likely feasible. There is one bishop pine, #8824, 20’ east of the trail edge. This tree has poor form, a forked top and is in fair condition. This tree can be successfully retained. Section 305 to 300 – Tree #8812 - #8815, #8825 - #8851 This segment is a mix of native species, evenly dispersed throughout the segment. The most common species are Douglas-fir followed by western red cedar, big leaf maple, Oregon ash, Ponderosa pine and Pacific madrone. The majority of the trees in this segment will be retained. The Douglas-fir trees in this study area range from semi-mature to mature. Common defects include forked tops, leaning trunks, forked trunks with included bark and cambial ruptures. The Douglas-fir trees range from fair to excellent condition.

Monitor Tree

Tree #8839 is an over mature Oregon ash tree over 20’ west of the property line. This tree has low vigor and significant crown dieback. Section 300 to 295 – Tree #8852 - #8863 This segment has a mix of tree species. The tree species in order of abundance are Douglas-fir, big leaf maple, pacific madrone, Atlas cedar, scots pine and Norway maple. There are two pacific madrone trees, #8860 and #8862, both trees are leaning and have crown dieback. These trees are in fair condition. One is located within the C&G limits and adjacent to the cut line and will have to be removed.

Monitor Tree #8861 is a big leaf maple with five co-dominant stems 27’ east of the trail edge, close to the C&G limits. Some of the tree trunks lean towards the trail and could be problematic in the future. Section 295 to 290 – Tree #8864 - #8876 This segment is primarily native tree species. There are few trees in this segment. The majority are western red cedar trees and big leaf maple trees. There are additionally two Scot’s pines. The majority of the big leaf maple trees have co-dominant stems as their primary defect. The western red cedar trees are in good condition and are viable. Segment 290 to 285 – Tree #8877 - #8879 This segment has very few significant trees. There are a lot of invasive species in this segment, primarily Himalayan blackberry. All three significant trees are far from the trail and will be retained.

9. Analysis and Testing No laboratory testing was initiated as part of this assignment.

10. Conclusions A total of 254 significant trees existing within the proposed clearing limits will need to be removed to make way for trail improvements. The vast majority of these are young to semi-mature specimens that were planted. All trees, both significant and non-significant to be removed from within the proposed clearing limits are listed on the attached tree summary tables.

A total of 19 significant trees outside of the proposed clearing limits are recommended for removal. Information for these trees can be found on the attached tables. These are trees that are in serious decline, and/or have developed significant defect and have a high potential to fail toward the trail and/or will be compromised by construction. The removals primarily involve red alder and black cottonwood trees that are declining and/or have developed excessive leans toward the trail. Removal is warranted to create a safe working environment and abate potentially hazardous conditions.

Of the 847 significant trees assessed, 144 are ‘Heritage’ trees (>22”) and 45 are ‘Landmark’ (>32”). Nine ‘Landmark’ trees and 40 ‘Heritage’ trees are proposed for removal. The recommended actions for subject trees that exist outside of the clearing and grading limits are provided on the attached tables. There are a few pruning recommendations to reduce current moderate to high risk conditions. Trees with a recommendation to monitor shall be periodically inspected during the construction phase. Once grade stakes and clearing limits are established on site, the assignment area shall be evaluated by the project arborist to ensure concurrence with the initial condition assessment and recommendations of this report. Cuts and fills shall be limited to the extent necessary for construction activities, and existing grades shall be left undisturbed where feasible to achieve the design standards of the improvements.

There is no warranty suggested for any of the trees subject to this report. Weather, latent tree conditions, and future man-caused activities could cause physiologic changes and deteriorating tree condition. Over time, deteriorating tree conditions may appear and there may be conditions, which are not now visible which, could cause tree failure. This report or the verbal comments made at the site in no way warrant the structural stability or long term condition of any tree, but represent my opinion based on the observations made.

Please call if you have any questions or if we can be of further assistance.
