Technical and scientific work done in 2015-2016

Partners: Coastal Zones Research Institute Inc., Geomediatix innovations Inc., The Acadian Peninsula Regional Service Commission, Department of Environment and Local Government, Department of Energy and Mines 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 projection
  • database of infrastructures at risk based on various flood and shoreline recession scenarios

Maps and zoning

Strategic planning exercise by a working group of the community in the fall of 2015

Members of the working group: Monique Gionet, Daniel Chiasson, Yvon Thériault, Mélodie Leblanc, Mariette Paulin, Sonia Leblanc and Chantale Gionet

Facilitation: CZRI

Recommendations:
  • Use the 2100 sea level rise scenario, the 100-year storm surge scenario at HHWLT, and the 2100 shoreline recession scenario for purposes of planning and delineating the areas at risk.
  • Amend the Town of Caraquet municipal plan to include zoning aimed at minimizing flood and erosion risks:
1) a retreat zone to minimize the risks of erosion and flooding, delineated by the line illustrating the projected position of the shoreline in 2100, by the area that would be flooded by a 100-year storm surge in 2100 (with the exception of the port area), the provincial wetlands and Caraquet Island.

2) an accommodation zone to minimize the risks of flooding delineated by the industrial and institutional port infrastructure zone flooded by the a 100-year storm surge in 2100.

Priorities and potential strategies

Strategic planning exercise by a working group from the community in the fall of 2016.

Members of the working group: Florence Albert, Daniel Chiasson, Monique Gionet, Yvon Thériault and Mariette Paulin

Facilitation: CZRI

Recommendations : 

The priority areas are :

  • Industrial and institutional port infrastructure zone
  • McIntosh bridge and access road to Bas-Caraquet
  • Pinet and Dugas streets

The priority area is the industrial and institutional port infrastructure zone. The working group advocates accommodation strategies for this area and recommends adding the following conditions to the regulatory measures recommended by the previous group: for new constructions, the first floor should be above the flood level, flood resistant materials should be used and a document attesting that they assume full responsibility for the risks should be signed by the owners.

For the access road to Bas-Caraquet and the McIntosh Bridge, the group advocates accommodation strategies. The strategies recommended are to raise the bridge and road sections at risk above the flood level and to inform emergency measures officials of flood risks (that the road could be impassable for an undefined period). For Pinet and Dugas streets, the group recommends that the only protection solutions allowed are those that cannot affect the aquaculture zone (the sector is near important oyster rearing leases).

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.
