PPRN: Flood Risk Prevention Plan for Lorey Municipality

Submersible Surface Plans (PSS) are the first documents regulating land cover in French flood zones, created by a 1935 decree. The Barnier Law of 1995 gave these plans the status of enforceable risk prevention plans (PPR), establishing utility easements on land use. The data, provided by the Bureau de Recherches Géologiques et Minières and last updated in April 2019, maps flood hazards and regulatory zoning for the municipality of Lorey.

Use Cases

• Assess land development suitability based on flood hazard zoning described in the PSS/PPR regulations.
• Model regulatory compliance for construction projects in areas with utility easements for water flow.
• Analyze historical flood risk mapping evolution from Submersible Surface Plans to modern Risk Prevention Plans.

Strengths

• Based on legally enforceable regulations (Barnier Law of 1995) with direct implications for land use.
• Originates from a recognized geological and mining research organization (Bureau de Recherches Géologiques et Minières).
• Describes a specific regulatory framework distinguishing between hazard mapping (PSS) and risk assessment (PPR).
