Abstract

The Ministry of Transportation (MoT) of the Province of British Columbia (B.C.), Canada, noise abatement policy requires that community noise impacts of highway projects involving new or substantially upgraded highways be assessed and mitigation implemented where warranted. Increasing community demands for noise mitigation, however, may exceed policy standards and pose greater challenges for designers. This paper presents an extraordinary noise model developed to mitigate residential areas of the Village of Lions Bay on the rugged B.C. coastline along the Sea-to-Sky Highway connecting Vancouver, B.C. to Whistler, B.C., Canada home of the Vancouver 2010 Winter Olympic and Para-Olympic Games. The CadnaA Version 3.9.15 software was used to develop a new four-lane split-grade alignment model incorporating two mini-interchanges. With the objective of achieving a 10 dBA noise reduction benefit, mitigation in the form of quiet pavement (OGAFC), traffic calming and 5 meter high sound walls were introduced into the model which included 115 mountain side residential receptors along a 2 km corridor at elevations of up to 35 meters above the highway. Noise reduction benefits and impacts for dwellings were further analyzed to determine contributions during specific stages of project development by creating a modular, multi-layer noise model of Lions Bay. This work was carried out under the sponsorship of BC MoT.
