Noise and Vibration - Lakeshore East Joint Corridor

← Return to Early Works: Lakeshore East Joint Corridor

Key Findings

Construction Noise

  • The impact assessment conservatively assumed that all construction equipment would operate in a small work area closest to each sensitive receiver* instead of being spread throughout the project footprint.
  • Without mitigation, there is potential for noise assessment criteria exceedances at the residential developments at 9 Lewis Street, 18 Saulter Street, 89 McGee Street, 812 Queen Street East**, 14 Wardell Street, 2 Paisley Avenue, 1054 Dundas Street, 15 Tiverton Avenue, 444 and 445 Logan Avenue, 138 First Street, 383 Gerrard Street, 885 Gerrard Street East, 400 Carlaw Avenue, 369 Pape Avenue, 2 Egan Avenue and 165 Galt Avenue.
  • To reduce potential impacts, appropriate mitigation measures (see Potential Effects & Mitigation Measures) will be implemented in addition to the development and implementation of a plan to manage construction noise before construction begins.

* A sensitive receiver is a location that is sensitive to noise, where noise is assessed. These locations include living and sleeping quarters of residences, and sleeping quarters of noise sensitive institutional/commercial land uses (e.g., hotel, hospital, etc.).
**812 Queen Street East is representative of the potential impacts at 791 Queen Street East, a Fontbonne residence

Construction Vibration

  • The impact assessment employed a conservative approach, where construction equipment was assumed to operate at the edge of the project footprint, closest to sensitive receivers.
  • Without mitigation, there is potential for vibration criteria exceedances at 9/11 Lewis Street, 20 and 33 Saulter Street, 1 Strange Street, 791 Queen Street East, 400 Eastern Avenue, 7/9 Dibble Street, 38/46, 56, 70 and 80 McGee Street, 870 Queen Street East, 2-14 Paisley Avenue, 15-17 Tiverton Avenue, 388-400 and 444-445 Logan Avenue, 231, 234-238 First Avenue, 843 Gerrard Street East, 400 Carlaw Avenue, 369 Pape Avenue, 1 and 2 Egan Avenue, 302-304 Jones Avenue, 162 and 165 Galt Avenue and 1000 Gerrard Street East.
  • Potential for exceedances will be reduced by implementing appropriate mitigation measures (see Potential Effects & Mitigation Measures) and through development and implementation of a plan to manage construction vibration before construction begins.

Operational noise and vibration associated with increased GO service levels as well as planned Ontario Line operations in the Lakeshore East Joint Corridor are assessed in the Lakeshore East Joint Corridor Noise and Vibration Operations Report included in Appendix C of this Draft Lakeshore East Joint Corridor Early Works Report.

Potential Effects & Mitigation Measures

Construction Noise

Potential Effects:

  • Without mitigation, potential for noise level criteria exceedances at a number of nearby sensitive receivers (see Key Findings for details).

Mitigation Measures:

  • Establish and apply project-specific construction noise criteria/exposure limit.
  • Use construction equipment compliant with noise level specifications in the Ministry of the Environment, Conservation and Parks’ NPC-115 and NPC-118 guidelines.
  • Keep equipment in good working order and operate with effective muffling devices.
  • Evaluate acoustic equipment enclosures for equipment such as compressors and generators.
  • Use of upgraded construction hoarding (considering requirements from CSA Z107.9 for noise barriers) between construction equipment and noise sensitive receivers.
  • Use of localized noise barriers for specific equipment and operations, including on corridor construction works where applicable.
  • Reduce simultaneous operation of equipment where possible.
  • Implement a no idling policy on site (unless necessary for equipment operation).
  • Restrict construction hours where possible:
    • perform construction during daytime hours where possible;
    • if nighttime construction is necessary, activities with the highest noise levels should be conducted during daytime periods; and
    • if construction will occur outside of normal daytime hours, inform local residents of type of construction and expected duration prior to commencing work.
  • Undertake noise monitoring and regular reporting throughout the construction phase as required.

Develop a communications protocol for providing advance construction and vibration impact notices and addressing public complaints in a timely manner.

Potential Effects & Mitigation Measures

Construction Vibration

Potential Effects:

  • Without mitigation, potential for vibration level criteria exceedances at a number of nearby sensitive receivers (see Key Findings for details).

Mitigation Measures:

  • Utilize equipment with low vibration emissions where possible.
  • Conduct off-site construction of components away from sensitive areas where possible.
  • Operate construction equipment on lower vibration settings where available.
  • Provide smooth surfaces for trucks to travel.
  • Maximize distance between equipment and sensitive receivers.
  • Restrict construction hours where possible:
    • perform construction during daytime hours where possible. If nighttime construction is necessary, the activities with the highest vibration levels should be conducted during daytime periods; and
    • if construction will occur outside of normal daytime hours, inform local residents in advance, describing type of construction and expected duration.
  • Use alternative construction methods and/or equipment with lower vibration emissions or power settings, where City of Toronto prohibited limits are predicted to be exceeded.
  • Conduct monitoring and pre-construction inspections in accordance with City of Toronto Bylaw 514 as required.
  • Develop a communications protocol for providing advance construction noise and vibration impact notices and addressing public complaints in a timely manner
