Special Intervention Zone 2017-2019: Flood Zone Perimeter for Quebec

A geospatial layer delimiting the perimeter of the 2017-2019 flooded area declared as a special intervention zone in Quebec. The Government and Municipalities of Québec created this zone using data sources from the 2017 and 2019 floods, and it was last updated on the platform in April 2026. The dataset is available under a CC-BY-4.0 license.

Use Cases

• Mapping flood risk areas for urban planning based on the declared special intervention zone perimeter.
• Analyzing historical flood extents for disaster preparedness based on the combined 2017 and 2019 data.
• Integrating regulatory boundaries into environmental impact assessments based on the decree's annex.

Strengths

• Data is derived from multiple sources covering two major flood events (2017 and 2019).
• Represents an official regulatory boundary defined by a government decree.
• Available in multiple geospatial formats (FGDB/GDB, GPKG, PDF).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• The description metadata is limited and was translated via an automated tool.
