P.O. Box 2013 Woodinville, WA 98072 425.483.9254 tom@olympicnursery.com www.olympicnursery.com OLYMPIC NURSERY, INC. | OLYMPICNURSERY.COM NARRATIVE Scope of Work You have asked me to assist you with the preparation of a Routine Vegetation Management report associated with code enforcement action following the removal of certain trees at the above referenced site. Methodology The methods used for this assessment are as outlined in Tree Risk Assessment by Julian Dunster and as adopted by the International Society of Arboriculture (ISA). The end goal of most assessments is to provide the owner or manager of the tree(s) with factual information, enabling them to make decisions about the management of the tree(s). While the purpose of this report is not tree risk assessment specifically, the overall site assessment utilizes the principals of risk assessment. In this case, certain trees were removed without permit and you have been directed to plant replacement trees on-site or to mitigate in other ways. Existing trees were tagged with a metal numbered tag for future reference. The stumps of recently cut trees were also tagged for reference. Findings and Observations I first visited the site June 10th 2017. I noted six (6) trees located on the site with an additional five (5) recently cut stumps. The six remaining trees were assessed to be in ‘Fair’ to ‘Good’ condition. Tree #64 and #65 have missing foliage as a result of the foliage of nearby trees that were removed. These defoliated areas may regenerate new growth but it will be slow and take many years. Considerations You have provided a list of the species, quantity, and replanting location of the replacement trees. This information is as detailed in the Tree Retention and Replanting plan dated 1/9/2018 and as submitted together with this written report. The replacement trees and the replanting thereof should conform to the standards detailed in Renton Municipal Code. Conclusions I have reviewed the Tree Retention and Replanting Plan dated 1/9/2018. The planting locations detailed on said site plan should be considered as a guideline. Actual planting locations might be dictated by actual on-site location of existing stumps or other hardscape elements.
