Flood Risk Prevention Plan (PPRI) Zoning for the Gulf of Saint-Florent, Corsica

The Gulf of Saint-Florent in Upper Corsica is covered by this regulatory zoning dataset for flood risk prevention. The dataset was last updated on December 20, 2021, by the French Geological Survey (BRGM). It classifies land into zones based on hazard levels to control urban development in areas at risk.

Use Cases

• Assess land development suitability based on regulatory flood zones.
• Model flood hazard exposure for the Aliso, Concia, Strutta, and Poggio catchment areas.
• Analyze zoning compliance for construction projects in 'red' (no-building) and 'blue' (prescribed) zones.

Strengths

• Based on a defined legal framework (French Act of 2 February 1995 and Environmental Code).
• Provides a clear, enforceable regulatory classification (red, blue zones).
• Covers a specific geographic scope: four municipalities in Upper Corsica.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2021.12.20; freshness should be verified.
• Row count and file size are unknown, which may limit suitability assessment.
