Arborist Report

1. The address of the subject lot.
2. The author, contact information, and relevant qualifications (e.g., ISA, RPF) with certification number.
3. The date(s) that the assessment was conducted, methodology and limitations; ensure assessments were completed within the last year (365 days).  Where reports are revised, include the revised report number and date.
4. An overview of the proposed work and explain what arboricultural work is to be undertaken for each tree(s) (e.g., tree to be injured, tree to be destroyed (removed), tree to be fully preserved and protected).
5. The description for tree species, size, condition and ownership for those that are 10cm DBH or greater on the subject lot and within 6m of the subject lot, inclusive of public property.
6. Where applicable, the specific reason(s) (e.g., new sanitary service) for destruction (removal) per tree. Alternate layouts and construction measures should be considered and discussed within the report to ensure all proposed removals are necessary and justified (i.e., there are no alternatives).
7. Where applicable, where construction activities will be in the minimum tree protection zone a description of the mitigation measures to be implemented to minimize impacts (e.g., exploratory air-spade and root prune). The prescription of mitigative measures should be carried to the tree inventory table and labelled appropriately on the tree protection plans for ease of use by the contractor.
8. Where applicable, a description of the methods to be implemented to ensure no impacts for those trees identified for full preservation (i.e., no encroachment).
9. Tree inventory (table of tree details) (refer to the tree inventory section).
10. Please ensure that all multi-stem trees are shown as one consolidated caliper in the chart using the sum of squares method below:
    Method 1 – Measure the diameter at breast-height (DBH) of each trunk. The DBH for the tree is found by taking the square root of the sum of all squared stem DBHs rounding to the nearest whole number. Example: You have three stems that all measure 5”, 6” and 8” so the DBH would be √(5²+6²+8²) = √(25+36+64)= √(125)=11”. It should be noted in the comments that it is a multi-stem tree.
11. Please ensure within the arborist report there is reference to either the number of replacement of trees, cash-in-lieu, or a combination of both (if applicable). Please make sure that the numerical costs are excluded, as City staff will be responsible for determining those.
12. Confirmation that the Tree Protection Zones established and maintained around any trees on the property and all mitigative measures prescribed are in accordance with the City’s relevant policies, procedures, and specifications, in accordance with City’s Tree Protection and Preservation Specification SS12A. Visit the Forest Protection and Tree Permits page for more information.
13. Where applicable the minimum frequency of site inspections by a qualified tree professional during proposed works
14. Recommendations for post-construction care and/or monitoring (as required) for regulated trees and proposed replacement trees.
15. Please indicate if a subsequent hazard tree management report may be applicable to the subject lot.
16. Where applicable a consent letter for the removal of boundary tree(s) (those located along the shared property line) or a neighbour tree(s) to be attached to the report document  
17. Where applicable a consent letter for the injury to a boundary and/or neighbour tree(s) to be attached to the report document or an attestation.
18. Where applicable any additional relevant information (e.g., legal survey, TRAQ form, pre-construction exploratory review etc.) to be attached to the report document.
19. Abbreviations should be defined, and industry standard terminology used.

   Method 1 – Measure the DBH of each trunk. The DBH for the tree is found by taking the square root of the sum of all squared stem DBHs rounding to the nearest whole number. Example: You have three stems that all measure 5”, 6” and 8” so the DBH would be √(5²+6²+8²) = √(25+36+64)= √(125)= 11”. It should be noted in the comments that it is a multi-stem tree. 
5. Provide the health and structural condition rating for each tree as a percentage (per cent) or as a description, i.e., E: excellent= 90per cent, G: good= 80per cent, FG: fair/good= 70per cent, F: fair= 60per cent, FP: fair/poor= 50per cent, P: poor= 35per cent, VP: very poor= 20per cent.

8. Tree ownership (i.e., private, public, boundary, neighbour) and corresponding address. Where multiple types of public property are identified, please further clarify the public property (e.g., public row, public parkland, public creek corridor or creek block) so it is clear. City staff may require verification by legal survey.
9. Please identify the proposed recommendation for each tree, i.e., preserve, injury (encroachment), destruction (removal).
10. Please include the Critical Root Zone (CRZ) as identified in the City’s specification document.

A Public Tree Permit will be required for any public trees regardless of development type. The checklist criteria for the Arborist Report, Tree Preservation Plan and Tree Inventory Table should coincide with the development types listed above.
