Flood Risk Prevention Plan Regulatory Zoning for Marne and Blaise Rivers

Regulatory zoning maps for the flood risk prevention plan (PPRi) in the Marne-Blaise sector near Vitry-le-François. The dataset classifies areas into zones such as 'red' (building prohibited), 'magenta' (subject to requirements), and 'white' (no hazard) based on hazard levels and land use. The data was published by the Bureau de Recherches Géologiques et Minières and last updated in April 2019.

Use Cases

• Identify land parcels where construction is prohibited based on 'red' or 'pink' zone classifications.
• Assess regulatory requirements for new projects in 'magenta' or 'blue' zones subject to specific building measures.
• Map areas with no flood hazard ('white zones') to understand the full scope of the regulatory plan.
• Analyze the spatial distribution of flood risk zones relative to existing built, agricultural, or natural areas.

Strengths

• Regulatory framework is clearly defined, referencing specific articles of the French Environmental Code (L562-1).
• Zoning logic is explicitly described, distinguishing between five types of zones based on hazard and land use.
• Data originates from a recognized geological and mining research organization (Bureau de Recherches Géologiques et Minières).

Limitations

• Last updated 2019-04-04 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
