Risk Prevention Plans for Natural Floods in Garonne Municipalities

Risk Prevention Plans (PPR) are France's key state instrument for monitoring development in areas exposed to major natural hazards. Each plan contains a presentation note, regulatory zoning maps, and regulations, linked to a GASPAR administrative procedure code. The data is provided by the Bureau de Recherches Géologiques et Minières and was last updated in July 2021.

Use Cases

• Mapping flood risk zones based on regulatory zoning plans.
• Analyzing land-use restrictions for construction and agriculture based on plan regulations.
• Tracking the administrative status (prescribed, approved) of risk prevention procedures.

Strengths

• Data is linked to official GASPAR administrative procedure codes (e.g., ddd[PREF|DDT|DDTM|DREAL]aaaannnn).
• Plans include multiple document types: a presentation note, zoning plans, and a regulation.

Limitations

• Last updated 2021-07-22 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
