Regulatory zoning data for the natural flood risk prevention plan (PPRi) in the Val du Bec d’Allier and Val de Givry areas of Nièvre, France. The dataset was last updated on May 4, 2021, and originates from the Bureau de Recherches Géologiques et Minières (BRGM). It categorizes land into zones based on hazard levels, such as 'red areas' where construction is prohibited and 'blue zones' where projects are subject to specific requirements.
Use Cases
- Assess land suitability for construction based on flood hazard zoning categories.
- Model flood risk exposure by analyzing the spatial distribution of 'red' and 'blue' zones.
- Inform regulatory compliance for development projects in areas with prescribed environmental measures.
Strengths
- Dataset is explicitly tied to a specific regulatory framework (PPRi) defined by the French Environmental Code.
- Zoning logic is clearly described, distinguishing between prohibited, prescribed, and risk-aggravation areas.
- Last update date of 2021-05-04 is provided.
