Priorities and potential strategies

Strategic planning exercise by a working group from Sainte-Marie-Saint-Raphaël, Cap-Bateau and Pigeon Hill 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 and Laurent Beaudin

Facilitation: CZRI and UMCS

The areas to be given priority are the:
1) Highway 305 into Pigeon Hill and the residences along the coast at the entrance to the Village of Pigeon Hill
2) Principal and secondary residences along the coast on Paulin Street in Sainte-Marie-Saint-Raphaël
3) 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.

Planning exercise by an internal committee in the fall of 2017 for preliminary strategy selection

Members of the internal committee: Conrad Godin, Caroline Ethier, Luc Levesque, Linda Lavoie, Sylvain Chiasson, Onile Mallet et Victor Landry

Facilitation: CZRI

Preliminary strategy selection:

The main strategies are:
• Amend the municipal development plan to include a retreat zone where no construction would be permitted, as delineated by the projected shoreline for 2100, as well as an accommodation zone, as delineated by the area that would be flooded by a 100-year storm surge in 2100.

• Regulate the use of protective structures.

• Create a registry of potential places to move to (available land, uninhabited houses that could be rented, houses for sale and apartments available in the Village) for owners at immediate risk of erosion.

• Inform the population of the erosion and flood risks specific to their area and of accommodation measures to limit damages.

Info - Public consultation

Implementation plan

The Village of Sainte-Marie-Saint-Raphaël has completed the process leading to the development of its Climate Change Adaptation Plan.

The final selection of actions in the plan was made following public consultation that took place in the fall of 2018.

An implementation plan has been developed including details of when and how the actions will be carried out.  The implementation plan will be updated as needed.

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.
