The City of Percé, QC, faces a serious shoreline erosion problem. This is particularly troubling for the small city because tourism is an important part of the local economy and the scenic views of the shoreline are a major attraction. The shoreline is being threatened by a combination of sea level rise, loss of ice cover, and changing weather patterns. Of particular concern is the area of Anse du Sud, a central commercial, tourist, and cultural hub for the community. This area was particularly hard hit by major winter storms in 2010 and 2016 with substantial damage occurring to the recreational and tourism areas during both storms. The area was protected by a sea wall which required investments from both the local and provincial government to keep standing in the face of repeated storm events. In the absence of these protection measures, it is estimated that the shoreline would erode at a rate of roughly 15cm per year. The report by Ouranos used a cost-benefit analysis to determine the most financially efficient means of protecting the shoreline and ultimately settled on the method of replenishing the local beach with pebbles. This method is estimated to produce a net benefit of approximately $68 million over the next 50 years.
Facing the erosion of their shoreline due to a combination of rising sea levels, loss of ice cover, and changing weather patterns, the Town of Percé, Quebec, undertook an intensive cost-benefit analysis to determine the most effective means of mitigating the potential damages. One of the major industries in the town is tourism, with the attractive beachfront along the Gulf of St. Lawrence being a major draw. Ouranos, a non-profit organization based out of Montreal, was conducting cost-benefit studies regarding mitigation practices in several municipalities, one of which was Percé. The cost-benefit study was conducted for the region of Gaspésie, thus the results are representative of the entire region. The partnership between the City and Ouranos eventually lead to a mitigation method that is predicted to save approximately $68 million for the region of Gaspésie over the next 50 years.
