Saint-Malo PPRSM: Marine Submersion Risk Zoning for Coastal Planning

Approved on 18/07/2017, this dataset contains the regulatory zoning for the Marine Submersion Natural Risk Prevention Plan (PPRSM) for the municipality of Saint-Malo in France. The plan demarcates areas exposed to marine flooding risk, prohibits or regulates construction, and defines preventive measures as per French Environmental Code Articles L 562-1 to L 562-7. It was created by the Bureau de Recherches Géologiques et Minières and incorporates considerations for climate change impacts on coastal hazards.

Use Cases

• Assess regulatory constraints on construction and development in coastal zones based on the plan's prohibitions and prescriptions.
• Model climate change impacts on coastal flooding hazards using the plan's incorporation of climate factors.
• Support civil security and major hazard prevention strategies based on the legal framework of Risk Prevention Plans (PPR).

Strengths
