Steps completed


Scenarios and risks

Technical and scientific work done between 2009 and 2011.

Partners: Université de Moncton, Shippagan campus, Department of the Environment and Local Government, Department of Energy and Resource Development

Results:
  • high-resolution field elevation model based on LiDAR data
  • sea level rise and storm surge level projections
  • shoreline recession and advancement projections
  • database of infrastructures at risk based on various flood and shoreline recession scenarios

Maps and zoning

Strategic planning exercise by a working group from the community in the fall of 2012.

Members of the working group: Jean-Marie Gionet, Gilles Savoie, Rino Thériault, Philip Boucher, Sylvie Gionet Doucet, Martin Haché and Denis Duguay
Facilitation: CZRI and APRSC

Recommendations:
  • Use the 2100 sea level rise scenario, the 100-year storm surge scenario at HHWLT, and the projected 2100 shoreline recession scenario for purposes of planning and delineating the areas at risk.
  • Amend the Village of Bas-Caraquet municipal plan to include zoning aimed at minimizing flood and erosion risks:
1) a retreat zone (no construction allowed), as delineated by the projected 2100 shoreline recession scenario, as well as wetlands

2) an accommodation zone where construction is allowed within certain conditions corresponding to the area flooded as per the 2055 100-year storm surge scenario.

3) an accommodation zone where construction is allowed within certain conditions corresponding to the area between the 2055 100-year storm surge scenario and the 2100 100-year storm surge scenario.

Priorities and potential strategies

Strategic planning exercise by a working group from the community in the fall of 2013.

Members of the working group: Jean-Marie Gionet, Gilles Savoie, Denis Duguay, Sylvie Gionet Doucet, Rino Thériault, Daniel C. Lanteigne and Nicolas Légère

Facilitation: CZRI

Recommendations:

The priority areas are : 

  • Village entrance, near Ruisseau Isabelle
  • Industrial park, wastewater retention basin and marina
  • Water supply pumping stations

The area located at the village entrance, near Ruisseau Isabelle, is especially at risk of flooding. This area is problematic given that it is flooded even without a major storm. The main elements at stake in this area are the access road to Bas-Caraquet, a pumping station, a water supply system and residences. The working group favours an accommodation strategy for this area.

Industrial park, wastewater retention basin and marina. The recommendations for the industrial park area originate from a protection strategy, notably, the extension of the existing protective structure (riprap) to the end of the jetty. For the other areas, recommended accommodation strategies are maintaining the retention basin above the flood level and informing the persons responsible for the marina of the risks of flooding and erosion; and the measures to be taken to minimize damage.

Several pumping stations in the Bas-Caraquet municipal water supply system are at risk of being submerged in the event of a flood. The working group recommends that all of them be raised above the flood level or replaced with submersible pumps, in accordance with the established order of priority and in consultation with public works officials in the Municipality of Bas-Caraquet.

Evaluation and selection of strategies

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

Members of the internal committee: Agnès Doiron, Roger Chiasson, Sylvio Lanteigne, Cyrénus Doiron, Anne-Marie Jourdain, René Friolet, Daniel Gionet et Richard Frigault

Facilitation: CZRI

Preliminary strategy selection:

The internal committee essentially retained the recommendations of the previous exercises. The main strategies are:

• Amend the municipal development plan to include zoning aimed at minimizing flood and erosion risks with conditions regarding the use and expansion of existing buildings and the use and construction of new buildings.

• Inform the population and infrastructure administrators (ex: port, marina, Chalets de la Plage, etc.) of the flood and erosion risks specific to their area and of accommodation measures to limit damages (temporary waterproofing like the use of sand bags or pumps, etc.).

• Develop a flood specific emergency plan that takes into account the priority areas and conduct practical exercises.

• Elevate certain infrastructures, such as roads, bridges and pumping stations that are at risk.

Info - Public consultation


Implementation plan

The Village of Bas-Caraquet 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.
