The trees was assessed on December 17th, 2024 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): • Big leaf maple, Acer macrophyllum • Approximately 27” DBH • Very large inclusion between two leaders • Split in the past, some response growth present • Leader that would be most likely to split is leaning toward a house • Failure within three years is probable, likelihood of impact is high, damage would be significant. High risk tree. Testing & Analysis: There were no soil, tree, or other physical testing. Discussion & Recommendation: The big leaf maple located in the green belt area near 3518 SE 18th St is a high risk tree at this point, based on a TRAQ assessment. There is a very large inclusion located at the union of the two leaders in the tree, which split in the past. There has been some response growth at this split, but there is still a probable likelihood that the leader closest to the house will fail at some point in the next three years. Although heavily reducing this stem would lower the risk of the tree to low-moderate, this is not an acceptable risk threshold for the community or the resident of the nearby home. The alternate and recommended mitigation is to snag the tree at 20 ft tall to lower the risk to an acceptable level while leaving wildlife habitat in place. Pictures of the tree proposed for removal are in Attachment A and the locations are 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 recommendation 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.
