 Outline commitments to future work and next steps

4. 4
Finch West LRT Maintenance and Storage Facility
 MSF site was selected based
on meeting criteria of size,
proximity to LRT line and site
availability
 The MSF will service up to 75
light rail vehicles (LRV) for the
Finch West LRT Line and
future Jane LRT Line
 Elements of the MSF include:
 Main Repair Shop
 Maintenance of Way
 Operations
 Electrical Substation

5. 5
Finch West LRT MSF Environmental Assessment
Process
 Step 1 (Preliminary Planning): Presenting the Site, Establishing
Conceptual Site Design, Documenting Existing Conditions, Preliminary
Identification of Potential Effects and Proposed Mitigation
 Step 2 (Transit Project Assessment Process): Detailed Assessment of
Effects, Preparation of Environmental Project Report, Public and Agency
review

6. 6
MSF Planning and Development Framework
The EA is carried out under Ontario
Regulation 231/08, Transit Project
Assessment Process (TPAP)
Metrolinx is partnering with Infrastructure
Ontario (IO) to develop the MSF and the Finch
West LRT
The project will be designed and constructed
using Infrastructure Ontario (IO’s) Alternative
Financing and Procurement (AFP) delivery
model which allows for technical innovation
IO plays a key role in Ontario’s long-term
infrastructure plan for public transit

7. 7
Recap of Public Open House #1
 Open House #1 provided an overview of the project and
existing environmental conditions forming the basis for effects
assessment
 The following common themes/concerns in regard to the MSF
were heard and addressed:
 Ensure Safety and Accessibility During Construction
 Investigate the Potential for Site Multi-Purpose Use of the
Site
 Minimize the Visual and Noise Impacts of the MSF

Effects Assessment Process
 Documented potential effects on:
 Natural Environment (Terrestrial, Aquatic, Geology and Hydrogeology)
 Traffic & Transportation
 Noise and Vibration
 Air Quality
 Socio-Economic Environment (Land Use, Visual Character, Community
Features)
 Developed measures to mitigate/minimize/compensate for
potential adverse effects
 Confirmed net or residual effects, if any
 Developed environmental monitoring to ensure the
implemented mitigation measures function as intended
The Effects Assessment for the Preferred MSF Concept Design was carried out
in accordance with Ontario Regulation 231/08 (TPAP), as follows:

15. 15
Natural Environment – Potential Effects & Mitigation
Potential Effects:
Removal of identified migratory birds nesting and associated on-site
vegetation
Permanent displacement of Species at Risk (SAR)
Mitigation:
Avoid vegetation removals during the typical nesting period of
migratory birds (May 1 to July 31) in accordance with the Migratory
Birds Convention Act, 1994
Develop Habitat Management Plan for the SAR in accordance with
O.Reg. 242/08 under Endangered Species Act, 2007
Maintain SAR compensation habitat for a period of 20 years,
including a minimum of 5 years of annual monitoring

16. 16
Noise – Potential Effects & Mitigation
Potential Effects:
Sensitive receptors may experience increased noise during
construction and operations
Mitigation:
Construction Noise Management Plan will be developed to address
noise generated during construction including a construction noise
complaint process and action plan
The MSF will be designed to meet operational noise requirements
of the Ministry of the Environment and Climate Change (MOECC)
document NPC-300 and MOEE/TTC Draft Protocol for Noise and
Vibration Assessment to minimize effects to:
 Residential dwellings
 Hotels
 Nursing Homes
 Schools
 Hospitals

17. 17
Potential Impacts:
Sensitive receptors may experience building damage during
construction and operations.
Mitigation:

Vibration – Potential Effects & Mitigation
Ballast Mats
•Reduces secondary airborne
noise and vibrations
Floating Slab Track Bed
•Protects vibration sensitive buildings
in the vicinity of tracks
Rubber Embedded Rail
•Reduces vibration levels
High Resilience Fastener (Rail Pad)
•Reduces vibration levels

18. 18
Air Quality – Potential Effects & Mitigation
Potential Effects:
Nuisance dust and emissions during construction.
Effects to local air quality during facility operations.
Mitigation:
Dust Management Plan will be developed to comply with
regulations and standards and to reduce dust during
construction.
Environmental Compliance Approval during detailed
design.
Other mitigation measures may include:
• Install ventilation/dust collection system for compressed
air cleaning of traction motors and selected roof-mounted
components.
• Locate stack for potential paint booth exhaust at least
20 m from nearest property line and design stack
parameters to ensure good dispersion (no rain caps).

19. 19
Transportation – Potential Effects & Mitigation
Potential Effects:
Increased travel times during
construction (Norfinch Dr. &
York Gate Blvd.).
Safety concerns for pedestrians
and cyclists.
Effects on existing TTC bus service.
Mitigation:
Divert traffic to parallel arterial and collector roads during traffic impact.
Incorporate signing, striping and active devices into design for
pedestrian and cyclist safety.
Liaise with TTC to address route requirements during construction.
Post appropriate signage and public notification during construction.
The construction of the Finch West LRT line has specific mitigation measures in the approved EA for the
Finch Line.

20. 20
Other Mitigation Measures During Construction
Measures will be implemented during construction to avoid, minimize or
mitigate adverse environmental effects including:
Erosion and sedimentation control
Development and implementation of traffic management plans
Construction staging and sequencing to mitigate the potential impacts
on local businesses to the extent possible
Ongoing management and monitoring of construction activities

21. 21
Other Mitigation Measures During
Operations and Maintenance
Measures will be implemented during LRT operations and
maintenance to avoid, minimize or mitigate adverse effects
including:
Stormwater run-off will be treated in accordance with applicable
City of Toronto, Toronto and Region Conservation Authority
(TRCA) and MOECC requirements
Noise, vibration and air emissions generated by LRT vehicles will
be attenuated to meet MOECC standards

22. 22
Commitments to Future Work
Following the approval of the Finch MSF EA, Metrolinx will proceed
with the delivery of the Finch West MSF through Public Private
Partnership and Alternative Financing and Procurement (AFP)
Through this process, Metrolinx is committed to:
Public Consultation: Consult with the public, property owners,
agencies and other stakeholders during the detailed design of the
MSF
Construction Mitigation: Develop mitigation plans, as necessary:
 Noise, vibration and air emissions monitoring and mitigation
 Traffic, transit and pedestrian management strategies
 Utility and municipal services relocation plans
 Landscaping plans
 Soil and groundwater management study
 Erosion and sedimentation control plan

 Please submit MSF EA comments to the
project team by July 8, 2015
 Comments received will be reviewed and considered by the
project team
 A Consultation Summary Report will be posted on the project
website in early August 2015
 Using feedback, the project team may refine mitigation and
monitoring for the site and finalize the Environmental Project
Report (EPR)
 A Notice of Completion will be filed in Summer 2015.
 The EPR will be available for a final 30-day public review period
