PPR Baliros: Flood Hazard Zones for the Pyrenees-Atlantiques Department

Hazard zones for the Baliros Flood Prevention Plan (PPR) in France's Pyrenees-Atlantiques department, last updated in 2019. The data represents areas exposed to one or more hazards, with zoning graduated by hazard level based on probability and intensity. It was produced by the Bureau de Recherches Géologiques et Minières (BRGM) and is disseminated as informative, non-enforceable GIS data.

Use Cases

• Mapping flood risk exposure based on the described hazard zoning.
• Analyzing hazard intensity and probability for land-use planning based on the described graduated zoning.
• Identifying areas protected by structures that are still considered subject to hazard based on the description of protective works.

Strengths

• Hazard levels are defined by a specific evaluation method for each hazard type, as described.
• The data includes areas protected by structures, which are represented as required by the standard.

Limitations

• The data is explicitly described as informative and not enforceable against third parties.
• Completeness and accuracy are not guaranteed relative to official documents.
• Column-level documentation is absent; field semantics must be inferred after download.
