Priorities and potential strategies

Strategic planning exercise by a working group from Grande-Anse and Anse-Bleue in the fall of 2015.

Members of the working group: Yves Landry, Ronald Thériault, Gino Benoit, Jean-François Chenard, Roland Landry and Gilbert Thériault



The priority areas are : 

  • Residential area of Anse-Bleue at risk of erosion and flooding
  • Grande-Anse and Anse-Bleue wharves

  1. The residential area of Anse-Bleue at risk of erosion and flooding, for which the main stakes are principal and secondary residences is a priority. The main strategies recommended for this area are accommodation and retreat measures. For example, limiting expansions of existing buildings (accommodation) or prohibiting new constructions (retreat).
  2. The subsequent priority areas are the wharves of Grande-Anse and Anse-Bleue, which represent stakes of economic and cultural importance to the communities. The working group recommends protection and accommodation measures for these areas. The main recommendations for other areas include retreat (relocation) for buildings at risk of erosion or the status quo.
  3. Regulations prohibiting all construction within less than 30 m (100 feet) of the shoreline should be re-implemented in Grande-Anse.

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.
