Isabella Street, Ottawa, Ontario June17, 2013 -1- 130293-rev.1 1.0 EXECUTIVE SUMMARY This Phase I Environmental Site Assessment was carried out by Kollaard Associates Inc. for Ashlar Homes of Ottawa, Ontario. The subject site for this assessment consists of a vacant property at civic address 114 Isabella Street, which occupies an area of about 341 square metres (0.08 acres), located south of Highway 417, between O’Connor and Metcalfe Streets, in the City of Ottawa, Ontario (See Key Plan, Figure 1). The purpose of the Phase I Environmental Site Assessment was to identify, if possible, through non-intrusive investigation, consisting of a review of current and historical information and observations of site conditions during a site reconnaissance visit, the existence of any significant, actual or potential environmental liabilities associated with the property. The Phase I Environmental Site Assessment (ESA) has been prepared in general conformity with our interpretation of the requirements of CSAZ768 as well as Ontario Regulation 153/04 (as amended in December 2009 through Ontario Regulation 511/09) for conducting environmental site assessments. The Phase I ESA was based on a site reconnaissance visit carried out on May 27, 2013, together with a review of available geological, topographical and historical information for the site. The results of this Phase I ESA indicate that the most significant environmentally related issues identified at the site are the potential for subsurface contamination related to presence of fill materials containing building debris from the former building at the site, which may contain deleterious materials, such as lead and asbestos. Vibrations and noise from the use of Isabella Street and Highway 417 may require special design considerations for future development at the site. There is also risk associated with off-site sources including the former use of the adjacent property east of the site, for which a clean-up and a Record of Site Condition were carried out in 2005. There is a risk for some hydrocarbon impacts due to the proximity of nearby automotive garage (Griffin Auto). If the risk of unknown contamination needs to be reduced, a program of soil and groundwater sampling together with appropriate laboratory testing could be carried out.
