R111-3: French Risk Prevention Plan Spatial Data for Approved Areas

Risk Prevention Plans (RPPs) are the French State's key instrument for controlling development in areas at risk. The R111-3 data package contains spatial datasets defining exposure scopes and restricted areas, including 'red' construction-prohibited zones and 'blue' zones with specific requirements. The data is provided by the Bureau de Recherches Géologiques et Minières and was last updated on 2021-02-18.

Use Cases

• Mapping construction-prohibited 'red zones' based on the plan's defined exposure scopes.
• Analyzing land-use requirements in 'blue zones' subject to specific hazard-adapted regulations.
• Identifying areas indirectly exposed to risks but still subject to prohibitions or requirements as described in the RPP regulations.

Strengths

• Data originates from the authoritative French geological and mining research bureau (BRGM).
• The description clearly outlines the regulatory framework ('red' and 'blue' zones) the data supports.

Limitations

• The description explicitly states the data is 'informative' and only paper documents with a prefecture's visa are authentic.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2021-02-18; freshness should be verified for current applications.
