ARBORIST INSPECTION 20 KAURI ST COOROY Professional Disclaimer: All trees are inspected on a basic level and ground based and should a higher level of inspection be required this will be identified and required to complete a mitigation response on individual trees. All trees are assessed on “normal weather conditions “and weather event outside this will be deemed an abnormal weather event and as this assessment results a higher level of risk than the initial assessment due to forces applied. After any weather event where there have been severe forces applied to the assessed trees, we strongly recommend a reinspection to keep your report current as this report prior to any event will be deemed defuncted until reinspected.

ARBORIST INSPECTION 20 KAURI ST COOROY Method of Inspection Kurt Brown employs a relevant section of multiple quantified modalities in his inspections, these are Matthecks VTA (Visual Tree Assessment) (Image 1) and ISA TRAQ Assessment. Kurt will also age profile the tree using the following classification in Appendix 2 and from this will give an approximate ULE (useful life expectancy)

ARBORIST INSPECTION 20 KAURI ST COOROY The following data was updated for the trees: • ID Number consistent with previous assessment or on a new site the initial numbering system • Image of tree • Botanic and common name • Tree dimensions (Height x Width) • Diameter at breast height (DBH) • Health • Structure • Useful life expectancy (ULE) • Age Class • Recommended works • Comments Appendix 1

Arborist Site Observations
At our inspection we have observed that this is bushland within a urban setting and has tall grasses present and that we have to assume the boundary
locations due to the site conditions. We don’t envisage much impact on the neighbouring trees but as outlined in AS 4970-2009 once the site is cleared and
marked out exactly and we will have to do another inspection and should there be conflicts in design / construction and vegetation then under the quoted
standard then protocols will be identified and implemented
