Box 13593, Ottawa, ON K2KK 1X6 Telephone: (613) Fax: (613) Website: Urban Forestry & Forest Management Consulting January 16, 2015 David Johnston Architect Ltd. 8 Maple Lane Unionville, ON L3R 1R2 Re: Tree Conservation Report 160 Hearst Way, Kanataa Dear David, This report details a pre-construc ction Tree Conservation Report (TCR) for the above-noted property in Ottawa. The need for this TCR is related to the future re-development of the property to accommodate a new hotel. Tree Conservation Reports are required for all plans of subdivision and site plan control applications for properties on whichh a tree of 10 centimetres in diameter or greater is present. The approval of this TCR by the City of Ottawa constitutes the permit to remove the approved trees. The inventory in this report details the assessment of both individuall and groupings of trees now present on the property. The construction proposed for the site includes a large building surrounded by parking, leaving little room to accommodate the growing space required by trees. Consequently most existing trees will be lost due to the proposed construction. However, all trees on the adjacent City and private properties can retained as they are far enough away from construction. Only three trees which conflict with construction are of suitable species, healthh conditionn and size which would allow them to be successfully transplanted out of the way and possibly used in the future landscape. TREE SPECIES, SIZE, CONDITIONN AND STATUS Table 1 below details the species, condition, size (diameter) and status of the trees on the subject property and in close proximity on adjacent private property. Each tree is referenced by the numbers plotted on the accompanying tree plan. Table 1. Tree No. 1 2 Species, condition, diameter and status of trees at 160 Hearst Way, Kanata.

Maturing tree; five-stemmed from grade; infested with EAB; to be removed The vegetative understory on the site, the shrub and regenerating tree layer beneath the mature trees detailed above, is dominated by staghorn sumac (Rhus typhina). Also present in the understory are honeysuckle (Lonicera spp.) and invasive buckthorn (Rhamnus asp.). In the large open areas of the property herbaceous species dominate: raspberry, spirea and grape vine (which is invading nearby trees). Also present are advancing sumac and scattered seedlings of black cherry, Eastern white cedar (Thuja occidentalis) and Manitoba maple (Acer negundo). Importantly, no butternuts (Juglans cinerea) were found on the property. Butternut is listed under the Province of Ontario s Endangered Species Act (2007) and is therefore protected from harm. Pictures 1 through 4 on pages 4, 5 and 6 show selected trees on 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. 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 if you have any questions concerning this Tree Conservation Report. Yours, Andrew Boyd Andrew K. Boyd, B.Sc.F., R.P.F.
