Priorities and potential strategies

Strategic planning exercise by a working group from Sainte-Marie-Saint-Raphaël, Cap-Bateau and Pigeon Hill done in the fall of 2013

Members of the working group: Conrad Godin, Alphonse Paulin, Renald Guignard, Mabel Guignard, André Mercier, George Savoie, Corinne Savoie, Rémi Hébert, Victor Landry, Gaston Guignard, Mélissa Duguay, Leroy Webster, Rosaline Beaudin et Laurent Beaudin

Facilitation: CZRI and UMCS


The areas to be given priority are the:

  • Highway 305 into Pigeon Hill and the residences along the coast at the entrance to the Village of Pigeon Hill
  • Principal and secondary residences along the coast on Paulin Street in Sainte-Marie-Saint-Raphaël
  • Section of Highway 305 crossing Cap-Bateau and the residences along the coast in Cap-Bateau.

The working group is advocating a gradual retreat strategy for all of these areas at risk of erosion. The main recommendations, which support a retreat strategy, call for the relocation of existing buildings by prioritizing principal residences and creating a retreat zone where any new construction would be prohibited. The working group recommends including a retreat zone where no new construction would be allowed, as delineated by the 2100 shoreline projection, in the Sainte-Marie-Saint-Raphaël municipal plan. The group also recommends that shoreline projections be computed for Cap-Bateau and Pigeon Hill.

Possible solutions

Adapting to climate change requires the implementation of several complementary measures on the same territory to ensure the safety of both the public and infrastructures. Here are some possible solutions.
