Risk Prevention Plans (PPRT): Land Use Regulations for the Loir-et-Cher Department

Risk Prevention Plans (PPR) are the French state's key instrument for monitoring development in areas exposed to major environmental risks. This geospatial dataset maps existing PPRT documents for the Loir-et-Cher department, linking each to its administrative procedure via a unique GASPAR code. The data was published by the Bureau de Recherches Géologiques et Minières and last updated in July 2019.

Use Cases

• Mapping regulated land-use zones based on the described regulatory zoning plans.
• Analyzing spatial coverage of risk prevention measures based on the polygon data for affected municipalities.
• Linking administrative procedures to geographic data using the unique GASPAR code format mentioned in the description.

Strengths

• Data is linked to formal administrative procedures via a structured GASPAR code (e.g., ddd[PREF|DDT|DDTM|DREAL]aaaannnn).
• Provides a geographic table for mapping existing plans across an entire French department.
• Based on a defined legal framework (the Act of 2 February 1995).

Limitations

• Last updated 2019-07-01 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the single department coverage.
