Grid of possible presence of a flood zone (data relating to old generation maps)

The standardized grid identifies sectors for which information on flood zones is available (old-generation maps, flood ratings, etc.). Contact [the municipality or the MRC] (https://www.quebec.ca/gouvernement/portrait-quebec/repertoire-municipalites) () to check if flood zone boundaries have been established on old-generation maps for a property .

The information disseminated in this grid comes from the following three sources of information (work has been done on the data to standardize everything):

[Territory flooded in 2017 and 2019] (https://www.donneesquebec.ca/recherche/dataset/territoire-inonde-en-2017-et-2019)
[2017-2019 Special Intervention Zone (from which territories covered by a ministerial decree are excluded)] (https://www.donneesquebec.ca/recherche/dataset/delimitation-du-perimetre-de-la-zone-d-intervention-speciale-zis-annexe2-modifie)
Mapping of flood zones identified by the MRCs and represented in the Provincial Land Use Portrait (PPAT) . For more details about the PPAT, consult the following page: [Application Territories - Provincial Land Use Portrait (PPAT)] (https://www.quebec.ca/habitation-territoire/amenagement-developpement-territoires/amenagement-territoire/systeme-information-gestion-amenagement-territoire/territoires#c256667)
