Regulated flood zones

A regulated flood zone is an area of land likely to be flooded and delimited by mapping or, along the St. Lawrence River, by flood ratings. On the territory of Quebec City, the only regulated and mapped flood zones are appended to the revised Land Use and Development Plan (SAD). These areas, which are added to the river's flood zone delimited by flood ratings, are subject to the special standards of the transitional regime for the management of flood zones, banks and coastlines since 1 March 2022. ATTENTION: The route indicating the boundaries of flood zones is for illustrative purposes only. Legal delimitation work must be validated in the field by a land surveyor for each property concerned. Quebec City declines all responsibility for the interpretation of available data. This third party metadata element was translated using an automated translation tool (Amazon Translate).
