Aiello, Landscape Architect 50 Camelot Drive Ottawa, ON K2G 5X8 RE: TREE CONSERVATION REPORT LES TERRASSES FRANCESCA Dear Gino, As per your request this report details a pre-construction Tree Conservation Report for the above-noted property in Ottawa. The need for this preliminary report is related to the future redevelopment of the site. The tree inventory in this report details the assessment of each individual tree now present on the property. Importantly, no endangered or other significant species were found to be present. Very little of the vegetation presently on the site is considered retainable as the construction of the proposed development and addition of surrounding hard surface areas will leave little room for trees to remain. Also the site servicing required beforehand, including that related to the underground parking will cause extensive disturbance to the entire site. The retention of existing trees under such circumstances is simply not realistic. The one exception is a line of mature Honeysuckle (Lonicera spp.) shrubs along the western property line. Furthermore no existing trees can be transplanted from the site and held for future use as none are of a species, size and/or health condition that would justify such as expense. It is anticipated that all trees situated on the adjacent properties can be retained. To this end preservation measures have been included to help reduce impacts of the proposed construction on these trees and the honeysuckle to be retained within the property. I have assumed all readers of this report are familiar with the general layout of the property and of the construction proposed for the site. 1

TREE PRESERVATION AND PROTECTION MEASURES The following measures are recommended 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. I trust that the above satisfies your requirements. Please do not hesitate to get in contact with me if you have any questions concerning this Tree Conservation Report. Yours, Andrew Boyd, B.Sc.F., R.P.F.

The need for this preliminary report is related to the future re-development of the site. Specifically, the tree inventory in this report details the assessment of individual trees on or in close proximity to the fence line along the north and east boundaries of the property. In many cases these trees are located on adjacent private properties. Importantly however, the existing fence does not represent the true location of the property lines. Instead it sits 0.5m to 1.2m inside the subject property. It is anticipated that all of the trees farther than 0.5m from the fence can be retained during construction. To this end preservation measures have been included to help reduce impacts of the proposed construction on their health. I have assumed all readers of this report are familiar with the general layout of the property and of the construction proposed for the site. TREE SPECIES, SIZE AND CONDITION Table 1 below details the species, condition, diameter and distance of each tree located in close proximity on adjacent properties: Tree No. A B C Tree Species Norway maple (Acer platanoides) Siberian elm (Ulmus pumila) Manitoba maple (Acer negundo) Condition (VP E) Approximate D.B.H (cm) / distance from property line (m) Tree Notes Fair 38/4.5 Highly invasive species; poor growth form Poor 55 & 66/2 Weak wooded species; secondary union very weakhazardous Fair 30 avg./0.25 Invasive species 1
