Arborist PN-6223A Tree Risk Assessment Qualified PO Box 3492 Redmond, WA 98073 Customer: Richard Hopkins and Neighbors 2511 Park Place N Renton, WA 98056 Introduction: This neighborhood group has concerns about the indicated volunteer cottonwood and maples on their property. Their concerns stem from the height of the trees, their age, and that they lean towards areas frequented by people. They are applying for a permit to remove them with intent to reduce the risk of damage to property and people should these trees fail. They believe these trees are adjacent to, or just within, boundaries of sloped areas, as determined using published maps by the city of Renton. There is also concern about financial liability should the trees fall and contact the Belle Vista Apartment building or cars in the apartment’s parking lot. The customer reported that one cottonwood fell into the parking lot area of Belle Vista apartments in late 2018 or early 2019, requiring a chain saw for removal. They is also concern about trees adjacent to The Friends of Youth sports field. Because these trees lean towards this field, they believe their failure would most likely fall across the facility’s sports track and into the sports field itself. Besides being a risk to the students, there is also risk of falling trees damaging sports equipment (e.g. soccer nets, etc.). Site location: A: West property line 2415 Park Pl N Renton, WA 98056 B: Southwest property line 2416 Park Pl N Renton, WA 98056 C: Southeast property line Friends of Youth 2500 Lake Washington Blvd. N Renton, WA 98056 Figures 1 and 2 show the locations of the trees evaluated in this report. A unique identifier is assigned to each tree. This identifier is used in supporting photographs and in the evaluation details for each tree. Species:  AREA A: 2 cottonwoods and 1 maple - attached are photos and TRAQ reports, showing photographic growth west towards the parking, pedestrians and Apartments. See Figures 8, 9, and 10.  AREA B: 6 cottonwoods - attached are photos and TRAQ reports, showing photographic growth west towards the parking, pedestrians and Apartments. See Figures 3 - 7.  AREA C: 3 cottonwoods and 1 maple - attached are photos and TRAQ reports, showing photographic growth toward and over play field, track and youth activity area. See Figures 11 and 12. Impact to Remaining Trees not Removed: The remaining trees are healthy at the time of inspection or are far enough away to not create risk. Arborist Notes: My findings show that there are multiple failures in the area where trees have uprooted, root failure, and low trunk breaks (possible low trunk rot, or wind shear). The trees are all growing toward pedestrian traffic, vehicle parking, and buildings (targets). I agree with property owners that the trees in questions should be removed or highly reduced to create a healthy buffer between green areas and targets. This is the only way I see to mitigate future harm or damage.
