UP Express Electrification EA Cultural Heritage Assessment Report FINAL Presented to: Metrolinx Project No. 1124019.00 March, 2014 Executive Summary Report Structure The purpose of this report is to: 1) establish baseline cultural heritage conditions and 2) to assess potential cultural heritage impacts of the proposed Union Pearson Express Electrification project, including proposed mitigation measures and net effects. This Cultural Heritage Assessment Report contains Parts A and B. Part A includes the Cultural Heritage Baseline Conditions Report, and Part B includes the Cultural Heritage Impact Assessment Report. Key Findings Studies conducted as part of the previous Environmental Assessment studies for the Georgetown South Service Expansion were reviewed to identify potential and known cultural heritage resources. Municipal heritage inventories from the City of Toronto and City of Mississauga were also reviewed to confirm accuracy of data presented in studies conducted as part of previous studies with regard to properties which have been listed on municipal registers and/or designated under the Ontario Heritage Act. Section 1 – UP Express Union Station to UP Express Bloor Station A total of five cultural heritage resources are expected to be impacted by the proposed work within Section 1. These include the Bathurst Street Bridge, the King Street Subway, the Dundas Street Bridge, the UP Express Rail Corridor, and the Fort York and Garrison Common National Historic Site and Heritage Conservation District; The Bathurst Street Bridge and the King Street Subway are listed by the City of Toronto as heritage properties. The Bathurst Street Bridge is also listed on the Ontario Heritage Bridge List; The Dundas Street Bridge and the UP Express Rail Corridor were identified as cultural heritage resources during the field review carried out for the Baseline Conditions phase of this project; o The Dundas Street Bridge was not found to meet cultural heritage criteria. Accordingly, no further work is recommended for this resource; and, o No negative impacts are anticipated to the UP Express Electrification Rail Corridor since the proposed undertaking will not affect any heritage attributes of this resource. Therefore, no further work is recommended for this resource. The Fort York and Garrison Common National Historic Site is designated under Part V of the Ontario Heritage Act and is a national historic site and heritage conservation district. Section 2 – UP Express Bloor Station to UP Express Weston Station A total of four cultural heritage resources are expected to be impacted by the proposed work within Section 2. These include the Wallace Avenue Pedestrian Bridge, the Rogers Road Bridge, the Jane Street Bridge, and 3500 Eglinton Avenue West (Kodak Lands); The Wallace Avenue Pedestrian Bridge is listed as a heritage property by the City of Toronto; The Rogers Road Bridge and Jane Street Bridge were identified as cultural heritage resources through background research; 3500 Eglinton Avenue West (Kodak Lands) is an industrial complex that has been evaluated and found to be a Provincial Heritage Property of Local Significance (pending conformation from Metrolinx). o Potential impacts and mitigation measures were previously captured in the Final Eglinton Crosstown LRT EPR Addendum. Therefore there are no new net adverse effects associated with locating the Paralleling Station on the Kodak site. Section 3 – UP Express Weston Station to Highway 427 One cultural heritage resources, the Humber River Bridge, is expected to be impacted by the proposed work within Section 3. The Humber River Bridge has been evaluated and found to be a Provincial Heritage Property of Local and Provincial Significance. Section 4 – Highway 417 to UP Express Pearson Station No impacts are anticipated to cultural heritage resources within or adjacent to Section 4 Footprint Impacts From a footprint impacts perspective, cultural heritage net effects are anticipated following the implementation of mitigation measures: Section 1 – UP Express Union Station to UP Express Bloor Station Bathurst Street Bridge and King Street Bridge: A Cultural Heritage Evaluation Report (CHER) should be carried out to identify the heritage attributes of these bridges. If found to retain cultural heritage value, then a Heritage Impact Assessment (HIA) should be carried out to identify impacts and develop appropriate mitigation measures. The HIA would be carried out during detail design and would be developed in consultation with the Ministry of Tourism, Culture and Sport and City of Toronto Heritage Preservation Services; Fort York and Garrison Common National Historic Site and Heritage Conservation District: Disruption to identified views would be mitigated through a Visual Impact Assessment (VIA), and disturbance of potential archaeological resources would be mitigated through Stage 1 and/or Stage 2 archaeological assessment. In addition, plans for the proposed Paralleling Station should be submitted to Heritage Preservation Services at the City of Toronto and the Friends of Fort York for review and comment prior to construction. Section 2 – UP Express Bloor Station to UP Express Weston Station Wallace Avenue Pedestrian Bridge, Rogers Road Bridge, and Jane Street Bridge: A CHER should be carried out to identify the heritage attributes of these bridges. If found to retain cultural heritage value, then a HIA should be carried out to identify impacts and develop appropriate mitigation measures. The HIA would be carried out during detail design and would be developed in consultation with the Ministry of Tourism, Culture and Sport and City of Toronto Heritage Preservation Services. Section 3 – UP Express Weston Station to Highway 427 Humber River Bridge: Foot print impacts to the Humber River Bridge would be mitigated through the development/implementation of a Conservation Plan. If the Conservation Plan does not account for impacts resulting from the current undertaking, or if a Conservation Plan does not yet exist, then a HIA should be carried out to identify impacts and propose appropriate mitigation measures. The HIA would be carried out during detail design and would be developed in consultation with the Ministry of Tourism, Culture and Sport and City of Toronto Heritage Preservation Services. Section 4 – Highway 417 to UP Express Pearson Station No footprint impacts are anticipated to cultural heritage resources within or adjacent to Section 4 Operations and Maintenance Impacts No negative impacts are anticipated to any cultural heritage resources in the study area resulting from the operation and maintenance of the UP Express Electrification system. Construction Impacts From a construction perspective, cultural heritage net effects are anticipated following the implementation of mitigation measures: Section 1 – UP Express Union Station to UP Express Bloor Station Bathurst Street Bridge and King Street Bridge: Short-term disruption minimized through selection of non-invasive staging areas, pre-construction vibration studies, post-construction landscape treatments, and avoidance of heritage attributes; Fort York and Garrison Common National Historic Site and Heritage Conservation District: Short- term disruption minimized through the selection of non-invasive staging areas, post-construction landscape treatments, and if possible, avoidance of heritage attributes. Section 2 – UP Express Bloor Station to UP Express Weston Station Wallace Avenue Pedestrian Bridge, Rogers Road Bridge, and Jane Street Bridge: Short-term disruption minimized through selection of non-invasive staging areas, pre-construction vibration studies, post-construction landscape treatments, and avoidance of heritage attributes; Section 3 – UP Express Weston Station to Highway 427 Humber River Bridge: Short-term impacts mitigated through the careful selection of staging areas, pre-construction vibration studies (if needed), and post-construction landscape treatment). Section 4 – Highway 417 to UP Express Pearson Station No construction impacts are anticipated to cultural heritage resources within or adjacent to Section 4 Part A – Baseline Conditions Report UP Express Electrification EA Baseline Conditions Report – Cultural Heritage TABLE OF CONTENTS – PART A EXECUTIVE SUMMARY ........................................................................................................................................... 2 GLOSSARY OF TERMS ............................................................................................................................................. 1 1.
