The Ministry of Transportation of Ontario (MTO) Central Region retained McIntosh Perry to complete a Detail Design and Group ‘C’ Class Environmental Assessment (Class EA) study for the rehabilitation of five structures on Highway 48 in the Town of East Gwillimbury and the Town of Georgina, Regional Municipality of York. McIntosh Perry was responsible for completion of a Cultural Heritage Assessment Report (CHAR) for the Highway 48 Black River/Baldwin River Bridge study area.
In response to the Notice of Study Commencement a local stakeholder expressed concerns regarding potential vibration impacts on structures with potential cultural heritage value or interest located adjacent to the Highway 48 Black River/Baldwin River Bridge study area. To address these concerns, a CHAR was conducted in order to identify, and document known or potential Cultural Heritage Resources (CHRs) and to provide a preliminary impact assessment of the proposed construction activities. Conservation and/or mitigation strategies were recommended, including but not limited to additional cultural heritage service reporting (i.e., CHERs, HIAs.) .
