Design Options Analysis - Strategic Considerations

Option #1:

Surface-running LRT, with 10 stops.

Noise of LRT Operations

Noise of LRT Operations

LRT produces about the same or less noise as general suburban traffic, about 60dB. Noise increase is at most 3dB, which is not considered significant. No additional noise mitigation is required.

Passenger Comfort/Experience

Passenger Comfort/ Experience

Passengers will have some exposure to weather conditions at surface stops. Impacts can be mitigated through shelter design.

Stop Access Considerations

Stop Access Considerations

Passengers will need to cross at least part of Eglinton Avenue to access median LRT stops. The absence of stairs, escalators and elevators help ensure access for all users.

Impacts to Natural/Green Spaces

Impacts to Natural and Environmentally Sensitive Areas and Green Spaces

Potentially lower impact to Natural Heritage and Environmentally Sensitive Areas, such as the Humber River Valley. Greater impact to vegetation along the corridor due to widening the roadbed along Eglinton Avenue West. Efforts would be made to mitigate potential impacts.

Connectivity

Connectivity

The number of stops (10) provides the best service to nearby residents and jobs. This option would provide direct connections to eight local and express TTC bus routes. No additional bus service will be required.

Option #2:

Underground LRT, with 10 stops.

Noise of LRT Operations

Noise of LRT Operations

Noise from an underground LRT is expected to be imperceptible from the surface.

Underground stations will provide shelter from weather conditions.

Stop Access Considerations

Stop Access Considerations

Passengers may not need to cross streets to access stations, depending on entrance locations (determined at a more detailed
design stage). Stairs, escalators and elevators to access underground stations would be required. Breakdowns could introduce potential barriers to access for some users.

Impacts to Natural/Green Spaces

Impacts to Natural and Environmentally Sensitive Areas and Green Spaces

Tunneled portion through the Humber River Valley and floodplains could impact the river and require significant flood mitigation measures. Potential for some impact to green spaces and vegetation along the corridor to accommodate station entrances and secondary structures. Efforts would be made to mitigate potential impacts.

Option #3:

Combination elevated and underground LRT, with 3 stops.

Noise of LRT Operations

Noise of LRT Operations

Noise from an underground LRT is expected to be imperceptible from the surface. Further work may be required to identify noise impacts from the elevated segment.

Passenger Comfort/Experience

Passenger Comfort/ Experience

Underground stations will provide shelter from weather conditions. Passengers will have some exposure to weather conditions at the elevated stop at Jane Street. Impacts can be mitigated through shelter design.

Stop Access Considerations

Stop Access Considerations

Passengers may not need to cross streets to access stations, depending on entrance locations (determined at a more detailed design stage). Stairs, escalators and elevators to access grade-separated stations would be required. Breakdowns could introduce potential barriers to access for some users.

Impacts to Natural/Green Spaces

Impacts to Natural and Environmentally Sensitive Areas and Green Spaces

Elevated structures through the Humber River Valley could have impacts to natural areas. Potential for some impact to green spaces and vegetation along the corridor to accommodate station entrances and secondary structures. Efforts would be made to mitigate potential impacts.

Connectivity

Connectivity

The number of stops (3) provides the least service to nearby residents and jobs. This option would provide direct connections to three local and express TTC bus routes. The TTC would be required to provide a parallel bus route along Eglinton Avenue to maintain local service.

Option #4:

Combination elevated and underground LRT, with 7 stops.
