24 Gaukel Street | Kitchener, Ontario
After completing Phase I and II Environmental Site Assessments (ESA), a Risk Assessment (RA) and a Designated Substance Audit (DSA), MTE successfully submitted a Record of Site Condition for the 0.22 hectares site at 24 Gaukel Street in Kitchener. Our Environmental team was initially retained to complete a due diligence site assessment in advance of the redevelopment. At the time, the site consisted of a two-storey building which included a service garage and retail fuel outlet as well as a coffee shop.
The potential purchaser had plans to demolish the building and redevelop the site into 31-storey residential building with commercial tenants on the ground floor and multiple levels of underground parking. Our initial investigation revealed multiple areas of identified impact, potential environmental risks related to current and earlier uses of the site and potential designated substances, leading our team to conduct a Phase Two ESA and remediation program.
Our team’s Phase Two ESA involved the advancement of 22 boreholes, with 16 of the boreholes completed as permanent monitoring wells in the Areas of Potential Environmental Concern (APEC) identified during our Phase One ESA. As a result, petroleum hydrocarbon, volatile organic compounds, inorganic (metals) and polycyclic aromatic hydrocarbon impacts were identified within the site and a Risk Assessment (RA) was developed to establish procedures for handling and placing material during redevelopment.
Through our RA, Risk Management Measures (RMs) were developed to mitigate exposure to humans and ecological receptors at the site. Our RMMs include a hard cap to block direct contact to soil and the installation of a vapour intrusion mitigation system.
Additionally, prior to demolition our team conducted a DSA in which asbestos, lead, mercury and ozone depleting substances were identified and abatement measures recommended along with a Structural Demolition Report. A Dewatering Assessment was also conducted with 20,000,000 L of dewatering required during construction.
