PPRN PSS: Flood Risk Regulatory Perimeters for Lay-Saint-Christophe, France

PSS (Submersible Surface Plans) are France's first regulatory maps for flood-prone land, created by a 1935 decree. This dataset contains the public utility easement perimeter for the municipality of Lay-Saint-Christophe, approved by a 1976 decree and managed by the Bureau de Recherches Géologiques et Minières. The data was last updated in April 2019 and is accessible via an INSPIRE download service.

Use Cases

• Mapping flood hazard zones based on the defined PSS regulatory perimeter.
• Assessing land-use compliance for construction permits based on the described utility easement rules.
• Historical analysis of flood risk policy by comparing PSS frameworks with modern PPR (Risk Prevention Plans).

Strengths

• Dataset is based on a legally approved perimeter from a specific 1976 decree.
