Technical and scientific work done in 2018

Partners: Coastal Zones Research Institute Inc. (Valorēs), Groupe Regenord Inc., The Acadian Peninsula Regional Service Commission, Department of Environment and Local Government, Department of Energy and Resource Development and Université de Moncton, Shippagan campus

Results:

  • High-resolution elevation model based on LiDAR data
  • Sea level rise and storm surge level projections
  • Shoreline recession and advancement projections
  • Database of infrastructure at risk based on various flood and shoreline recession scenarios

Priorities and potential strategies

Strategic planning exercise by a working group from Néguac from fall 2019 to winter 2020.

Members of the working group : Adrien Robichaud, Gérard Robichaud, Philippe J. Breau, Pierre Godin.

Facilitation: Valores (Coastal Zones Research Institute)

Recommendations:
The areas to be given priority are the:
1) Hay Island
2) Neguac wharf
3) Residences of Néguac central sector.
4) The school sector
5) Haut-Néguac sector
6) Bas-Néguac sector

The main recommendations of the working group concern the communication to citizens of the risks of erosion and flooding and establish prevention protocols via individual emergency plans. The working group also recommends including an inconstructible setback zone delimited by the coastline projected for 2100 in the Neguac development plan, as well as an accommodation zone where construction would be permitted but under certain conditions . These recommendations, which constitute a preliminary selection of adaptation strategies, will be submitted to the public for opinion during the second phase of the project, before the final drafting of Néguac's adaptation plan to climate change is started.

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.
