Special Intervention Zone (ZIS) 2019: Flood Management Perimeter in Quebec

A geospatial layer delineating the perimeter of the Special Intervention Zone (ZIS) established by decree to promote better flood zone management in Quebec. The zone was created using data on flooded areas from 2017 and 2019 and was in force from June 10 to July 15, 2019. This dataset, provided by the Government and Municipalities of Québec, is no longer in force as of the adoption of Decree 817-2019.

Use Cases

• Historical analysis of flood zone policy boundaries based on the 2017 and 2019 flood data mentioned in the description.
• GIS mapping of former regulatory perimeters for comparative studies with current flood zones.
• Assessing the spatial impact of the specific decree (June 10 - July 15, 2019) on land management.

Strengths

• Data is derived from multiple sources showing flooded areas for 2017 and 2019.
• Available under a permissive CC-BY-4.0 license.
• Provided in multiple geospatial formats (FGDB/GDB, GPKG, OTHER, PDF).

Limitations

• Dataset is explicitly stated to be no longer in force, limiting its operational use.
• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
