The West Calgary Ring Road is located within the province’s Transportation Utility Corridor and is subject to provincial noise reduction guidelines. The provincial guidelines for noise reduction are different than those used by the City of Calgary; however, they are consistent with the policies used within the City of Edmonton and other urban areas. The guidelines are regularly reviewed to ensure they remain applicable.
The noise reduction guidelines for provincial highways within cities and urban areas indicate an average noise level of 65 decibels over a 24-hour period is acceptable. The measurements are taken using an A-weighted filter 1.2 metres above ground level and two metres inside the property line (outside the highway right-of-way).
A noise study will be done as part of the project to determine if noise mitigation will be required. The results of the study will be shared once complete, and if noise mitigation is warranted, the project team will contact adjacent property residents.
