Gatineau is a resilient and proactive city when it comes to flooding. Thinking ahead is one of several essential steps to prepare ourselves and to guide our decisions about how to better protect citizens against future flooding.

Meetings with residents directly affected by flooding

The City wanted to hear from residents who have been directly affected by flooding and receive their recommendations and suggestions on how to mitigate flood risks. Four consultative sessions by invitation only were scheduled with residents directly affected by flooding in November and December 2020. The affected residents could take part in the consultative process by participating in the consultation scheduled for their district or by forwarding their suggestions by email. The committee of experts is preparing a report on the proposals received, which will be included among the recommendations made to the Council.

Advisory committee on flooding

The City of Gatineau has set up an advisory committee of well-known experts to guide municipal decisions on flooding. The committee's mandate is to advise the City on municipal planning and protective measures in flood-risk areas.

Guiding principles for the consultations with residents

The consultations will be based on the following principles that draw on those spelled out in the Sustainable Development Act:

  • “Social equity and solidarity”: Actions must be undertaken in a spirit of intra- and inter-generational equity and social ethics and solidarity;
  • “Prevention”: In the presence of a known risk, preventive, mitigating and corrective actions must be taken;
  • “Precaution”: When there are threats of serious or irreversible damage, lack of full scientific certainty must not be used as a reason for postponing the adoption of effective measures to prevent a degradation of citizens' quality of life;
  • “Health and quality of life”: People, human health and improved quality of life must be at the centre of concerns;
  • “Environmental protection”: Environmental protection must constitute an integral part of the evaluation process.

Advisory committee mandate

The mandate of the advisory committee is to make recommendations to the City on:

  • an updated map of risks associated with flooding and the vulnerability of physical elements exposed to these risks, according to the terms of the mandate to create an up-to-date map;
  • measures to reduce the flood-risk exposure of people, buildings, infrastructure and equipment;
  • the execution of public works and other protective measures;
  • the evaluation criteria for protective measures.

Submission of the committee's final report is slated for fall 2020. Once this has been done, the committee will have completed its mandate.

The membership of the advisory committee on municipal planning and protective measures in flood-risk areas is composed of the following experts:

Updating the flood-risk map for the Outaouais

Under a mandate from the Quebec government, the City of Gatineau is updating the flood-risk map for the Outaouais. This should be completed by spring 2020.

Participation in a municipal committee set up by the Government of Quebec

The City is also actively participating in discussing and implementing future flood-mitigation measures in Quebec.
