Department of Parks&Recreation Tree Risk Assessment—Honomu Park Banyan Trees I was instructed to visit the site and conduct a visual tree assessment on both Banyan trees in regards to structural stability, tree canopies growing over property lines and roots growing over property lines. Assignment Arborist Services has been requested to perform a visual tree assessment of the trees and determine if it is structurally sound and assess if the tree poses any threat to adjoining residents, property owners and existing County facilities. Arborist Services was also asked to provide any recommendations on tree maintenance that might be required to keep adjoining property and the public safe. The scope of work includes: 1. Perform an analysis of both trees as currently exist in general conformance with the methodologies set forward in the American National Standards Institute A300, Part 9 Tree Risk Assessment and the International Society of Arboriculture's Best Management Practices Tree Risk Assessment to determine the potential risk posed by both trees. 2. Meet with parties affected by the tree with assigned Department of Parks & Recreation (DPR) staff. Determine history of the trees if possible. 3. Provide a clear, detailed recommendation(s) on how any and all identified risks can reasonably be addressed by the County and the probability and frequency that those risks are likely to reoccur/reappear. Where there is more than one practicable option, provide such alternates to the County for consideration. 4. Provide a budgetary estimate on what the initial recommended course(s) of action would cost the County for a licensed (C-27b) tree trimming and removal contractor to perform said work. Where there is more than one practicable option or if work to achieve the desired end result can be phased incrementally, provide correspondingly detailed cost estimates. Also, where proper care for the trees requires recurring maintenance work (annually, biannually, semiannually, or otherwise) identify such and provide a corresponding description of this work along with budgetary costs. 5. Meet with the DPR prior to commencing work in order to develop greater familiarity with the issue, coordinate field work with so that a representative may be present when work is being performed, and meet with DPR to present and discuss the draft analysis and budgetary figures in greater detail and respond to any questions that may be posed. 6. Finalize the report and accompanying documents, which will be shared with the public. 2 Mark O'Dell, ISA Certified Arborist Arborist Services, LLC November 13, 2016
