In July 2019, the Government of Quebec passed a decree declaring a special intervention zone (ZIS) to promote better management of flood-prone areas. This decree imposes a moratorium on the construction of buildings in flood-prone areas and those that have already been flooded, and on the reconstruction of buildings destroyed by flooding.
On March 1, 2022, the provisions of the decree will be replaced by new ones passed by the Government of Quebec under the Environment Quality Act. These are interim provisions, which will be replaced as soon as the new flood area maps and regulations are passed by Quebec.
The interim provisions recognize two flood areas to which special conditions apply:
0 to 20-year recurrence areas (high-velocity); and
20 to 100-year recurrence areas (low-velocity). These areas include those that were flooded in 2019 and were not previously included in the flood-prone area maps.
Projects carried out in 0 to 20-year recurrence areas (high-velocity) or 20 to 100-year recurrence areas (low velocity area)are subject to land use constraints and authorizations.
To find out whether your property is located in a 0 to 20-year or a 20 to 100-year recurrence area, consult the Ville de Gatineau Atlas and:
enter the address or lot number in the space indicated as “Rechercher une adresse” and check “Aménagement du territoire”; and
check “Zones de récurrence de grand et faible courant”.
Applicable authorizations and standards in flood-prone areas
Quebec's interim provisions require that Ville de Gatineau issue a municipal consent for any construction, reconstruction or extension of a residential building and its accessory buildings located in a flood-prone area.
This requirement is in addition, where applicable, to the requirement to obtain a building permit or a certificate of authorization.
In the following, for easier reading:
we use the expression 0 to 20-year area for high-velocity areas, and 20 to 100-year area for low-velocity areas;
flood-prone areas include the 0 to 20-year and the 20 to 100-year areas; and
a residential building includes any building with at least one dwelling, and may also include commercial or service portions.
To facilitate the process of obtaining a municipal consent or building permit, Ville de Gatineau offers the option of applying online.
