Aiello, Landscape Architect 50 Camelot Drive Ottawa, ON K2G 5X8 May 18, 2017 RE: TREE CONSERVATION REPORT 2887 RIVERSIDE DRIVE, OTTAWA Dear Gino, This report details a pre-construction Tree Conservation Report (TCR) for the above-noted property in Ottawa. The need for this TCR is related to the re-development of the subject property. Such reports are required for all Plans of Subdivision and Site Plan Control Applications where there is a tree of 10 centimetres in diameter or greater on the property. The approval of this TCR by the City of Ottawa and the issuing of a permit by them authorize the removal of approved trees. No tree removal should occur before such a permit is issued. The inventory in this report details the assessment of all individual trees on the subject and adjacent properties. Field work for this report was completed on May 11, The construction proposed for the site includes a four-storey building with below ground parking and landscaping surrounding the new building. A combination of their poor condition and the excavation necessary for garage ramps will require the removal of most trees on the subject property. No privately-owned trees on adjacent private property will be adversely impacted by the proposed construction. A single tree located on City of Ottawa property is presently hazardous and so should be removed on this basis. The tree preservation and protection measures cited in this report will be followed to ensure the survival of the trees proposed for retention. TREE SPECIES, CONDITION, SIZE AND STATUS On the Table 1 on page 2 details the species, condition, size (diameter) and status of the individual trees on the subject and nearby City-owned lands. Each of these trees is referenced by the numbers plotted on the accompanying tree plan prepared by Gino J. Aiello, Landscape Architect. 1

Pictures 1 through 6 on pages 5, 6, 7 and 8 show selected trees on and adjacent to the subject property. TREE PRESERVATION AND PROTECTION MEASURES Preservation and protection measures intended to mitigate damage during construction will be applied for the trees to be retained on and adjacent to the subject property. The following measures are required by the City of Ottawa to ensure tree survival during construction: 1. Erect a fence at the critical root zone (CRZ 1 ) of trees; 2. Do not place any material or equipment within the CRZ of the tree; 3. Do not attach any signs, notices or posters to any tree; 4. Do not raise or lower the existing grade within the CRZ without approval; 5. Tunnel or bore when digging within the CRZ of a tree; 6. Do not damage the root system, trunk or branches of any tree; 7. Ensure that exhaust fumes from all equipment are NOT directed towards any tree's canopy. 1 The critical root zone (CRZ) is established as being 10 centimetres from the trunk of a tree for every centimetre of trunk Diameter at breast height (DBH). The CRZ is calculated as DBH x 10 cm. Please do not hesitate to contact me with any questions concerning this Tree Conservation Report. Yours, Andrew Boyd Andrew K. Boyd, B.Sc.F, R.P.F.
