Dataset Direct Download Service (WFS): Natural flood risk prevention plan — Municipalities

Risk Prevention Plans (PPR) are the key state instrument for monitoring development in areas exposed to major risks, established by the Act of 2 February 1995. Each plan is identified by a polygon corresponding to a set of municipalities and is linked to an administrative procedure via a GASPAR code. The dataset is provided by the Bureau de Recherches Géologiques et Minières and was last updated on 2021-07-22.

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 plans for municipalities.

Strengths

• Each plan is linked to a formal administrative procedure via a unique GASPAR code.
• Plans include regulatory zoning maps and documents detailing hazards and issues.
• Dataset provides a geographical table for mapping existing plans across a department.

Limitations

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