The tree was assessed on February 2nd, 2025 by Daniel Potts, ISA Certified Arborist #11534A. Assignment (and any limiting factors): The assignment is to perform a visual assessment regarding health condition, structural integrity, threat of pest or disease, and potential hazards. The visual inspection was from ground grade only. The assignment is to assess and provide recommendations for future action. Observations: At the time of the assessment, the following was observed (please refer to photos in Attachment A and locations in Attachment B): • Douglas fir, Pseudotsuga menziesii • 33.2” DBH • Approximately 110 ft tall, 40 ft crown diameter • Poor taper • Overextended branches • LCR is about 55-60% • Failure of a branch within three years is probable, likelihood of impact is high, damage would be minor. Moderate risk tree. Testing & Analysis: There were no soil, tree, or other physical testing. Discussion & Recommendation: The Douglas fir located in the green belt area near 3542 SE 18th St is in poor health with poor taper, overextended branches, and a LCR of 55-60%. At the time of assessment, the foliage was sparse, but there was some new growth present. There was a fence built very close to the trunk, which likely caused some root damage that may be contributing to poor health in the canopy. This was a retained tree, so the entire development of the community may have impacted the root system as well. The resident of the nearby house reported that branches have fallen onto the house twice in the past two years and damaged the roof last time they fell in winter of 2024. We are qualifying roof damage as minor damage, making the risk of this tree moderate, although branch failure in the next two years is probably with a high likelihood of impact. Although the risk rating of the tree is moderate, the resident has requested removal for their peace of mind. Removal is a reasonable option and would not be detrimental to the greenbelt area. Logs would be left in the greenbelt to serve as habitat. If removal is not approved by the city, snagging would be another option to mitigate risk. If neither of these are approved, monitoring of the tree is recommended to determine if the risk rating increases in the future. Pictures of the tree proposed for removal are in Attachment A and the location is in Attachment B. Arborist Disclaimer Arborists cannot detect every condition that could possibly lead to the structural failure of a tree. Trees are living organisms that may fail in ways we do not fully understand. Conditions are often hidden within trees and below ground. Arborists cannot guarantee that a tree will be healthy or safe, or fail for that matter, under all circumstances, or for a given period of time. Likewise, remedial treatments, like any medicine, cannot be guaranteed. Treatments, pruning and removal of trees may involve considerations beyond the scope of the arborist’s services such as property boundaries, property ownership, sight lines, disputes between neighbors, landlord-tenant matters, etc. Arborists cannot take such issues into account unless complete and accurate information is given to the arborist. The person hiring the arborist accepts full responsibility for authorizing the recommended treatment or remedial measures. Trees can be managed, but they cannot be controlled. To live near a tree is to accept some degree of risk. The only way to eliminate all risks is to eliminate all trees. This consultant does not verify the safety or health of any tree for any period of time. Construction activities are hazardous to trees and cause many short and long-term injuries, which can cause trees to die or topple. Even when every tree is inspected, inspection involves sampling; therefore, some areas of decay or weakness may be missed. Weather, winds and the magnitude and direction of storms are not predictable, and some failures may still occur despite the best application of high professional standards. I hereby declare that the above observations, discussion, and recommendations are true to the best of my knowledge, belief, and professional opinion. In addition, A Plus Tree is held harmless of any of these opinions from future tree failures.
