Traffic Noise Study

Background

The City has conducted a Traffic Noise Study, along arterial and collector roads, throughout St. Albert. The study monitored existing noise levels and gathered background data that will be used to assess traffic noise impacts, and if there is a need to change current noise policies or engineering standards. Results may be used to assess options for noise reduction and to identify priority areas.

Current City Noise Standards and Policies:

  • Technical Municipal Engineering Standards, subsection 3.9, provides direction for mitigation of noise levels above 65 dBA over a 24-hour period in proposed residential developments.
  • Noise Bylaw 31/2006 – applies to noises that are intermittent, unusual or unique in nature. Includes items such as noisy neighbours, construction work, or outdoor public-address systems.

Work Completed

The City hired a consultant, GHD Limited, to conduct noise monitoring throughout the City. The objective of this project was to collect actual field noise data at typical residential locations in proximity to arterial and collector roadways to determine the existing noise levels as related to traffic.  The information is proposed to be used to report back on real-world condition levels and perform an analysis to identify existing conditions compared to City or industry standards and policy.  Work involved placing noise monitoring equipment at set distances from roadways and residential properties throughout St. Albert. In total, forty-eight locations were selected throughout the city, and noise levels were monitored for a 24-hour period at each site.

The noise monitoring was completed in May and June of 2018, with a compilation of project information, background and study results completed and prepared as a final report.

Final Traffic Noise Monitoring Study

Next Steps

From the results of the project, and information captured within the City-Wide Traffic Noise Monitoring Study report (2018), the next steps involve an expansion of investigation at the specific sites that were reported as experiencing higher levels of noise. The objective is to capture the limits (from the singular point to actual “start” and “end” points) of where higher noise levels are being experienced along the roadways.  Once the larger boundary of the issue is defined, a more detailed site investigation and analysis of potential mitigation measures may be applied to reduce noise impacts.

Information obtained from this second phase will be used to inform on necessary funding requirements and development of project charters that may be considered within the 10-Year Capital Plan; or aligned within existing transportation network improvement programs.

Timeline

  • TBD: Phase 2 Noise Monitoring: Sites determined by results of Phase 1 study; investigating priority areas for identification of “boundaries” of noise issues.
  • TBD: Reporting on Phase 2 Results and Recommendations
  • NOTE: Phase 2 monitoring has been postponed due to variation in typical traffic volumes. Phase 2 will be re-evaluated in 2021 to determine if noise monitoring can proceed.
