PPRN: Flood Risk Regulatory Zoning for the Municipality of Saint-Mard, France

Submersible Surface Plans (PSS) are the first mapping documents regulating land cover in flooding areas for federal watercourses, created by a 1935 decree-law. This dataset contains the perimeter of the PSS for Saint-Mard, approved by decree in 1976, which establishes a public utility easement affecting land use. The data is provided by the Bureau de Recherches Géologiques et Minières and was last updated in April 2019.

Use Cases

• Mapping historical flood hazard zones based on the Submersible Surface Plan (PSS) framework.
• Analyzing land-use restrictions for property development based on the regulatory zoning described.
• Studying the evolution of flood risk policy by comparing PSS perimeters with modern Risk Prevention Plans (PPR).
• Assessing administrative utility easements affecting construction and land modification in flood-prone areas.

Strengths

• Dataset is based on a legally defined and approved regulatory zoning plan (Decree of 10 December 1976).
• The PSS framework has a defined legal status under the Barnier Law of 1995, providing enforceability.
• Data originates from the authoritative geological and mining research bureau (BRGM).

Limitations

• Last updated 2019-04-05 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.
