Scenarios and risks (Preparatory step)
Technical and scientific work done in 2014-2015
Partners: Université de Moncton, Moncton campus and Shippagan campus, Geomediatix Innovations Inc., Géo Littoral Consultants, Commission de l’environnement de Tracadie, Department of Environment and Local Government and Department of Energy and Resource Development
Results:
- high-resolution 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

Priorities and potential strategies
Strategic planning exercise by a working group from the community in the fall of 2015 (Maps and zoning)
Members of the working group: Weldon McLaughlin, Arthur Austin, Paul Roussel, Annette Bénard, Bruce Comeau, Napoléon Basque, Isabelle Paulin, Arthur Arseneau and Ginette Kervin
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 Regional municipality of Tracadie municipal plan to include zoning aimed at minimizing flood and erosion risks:
1) a retreat zone (no new construction and no expansion of existing buildings permitted) as delineated by the projected position of the shoreline in 2100, wetlands and coastal sand spits.
2) an accommodation zone to limit flood risks, delineated by the area that would be flooded by the 100-year storm surge in 2100.

Strategic planning exercise by a working group from the community in the fall of 2016 (Prioritazing strategies)
Members of the working group: Annette Bénard, Bruce Comeau, Alex Doiron, Ernest Ferguson, Weldon McLaughlin, Mario Noel, Linus Robichaud, Paul Roussel and Joannie Thériault
Facilitation: CZRI
Recommendations :
The priority areas are :
- Val-Comeau area, gulf side
- Sandspit area
- Pointe-à-Bouleau and Sureau Blanc street areas
- Lighthouse, wharf and the downtown walking trail areas
- Pointe-des-Robichaud and Val-Comeau areas, estuary side
The main recommendations of the working group are to develop emergency measures plans specifically for floods in the residential and harbour areas, to create a development plan to oversee new building and road constructions and existing road upgrades, to inform property owners of the risks and ways to minimize them, to use soft techniques to maintain and restore dunes and beaches, as well as to raise the roads and bridges in the flood risk zone, especially for critical accesses

Info - Public consultation
The final selection of actions that will be in the Regional Municipality of Tracadie’s Climate Change Adaptation Plan was made following the public consultation held in the fall of 2018.
