Submersible Surface Planes (PSS) are the first mapping documents regulating land cover in flooding areas for federal watercourses, created by decrees in 1935 and 1937. The dataset represents regulated areas under the Barnier Law of 1995, which gave PSS a risk prevention plan (PPR) status enforceable against third parties. It is provided by the Bureau de Recherches Géologiques et Minières and was last updated in April 2019.
Use Cases
- Mapping flood hazard zones based on the Submersible Surface Planes (PSS) regulatory framework.
- Assessing land-use restrictions for construction projects based on the 'red' (building prohibited) and 'blue' (prescribed) zoning categories.
- Evaluating regulatory compliance for works affecting water flow as defined by Article R425-21 of the Urban Code.
- Comparing historical PSS flood mapping ('average' flood) with modern PPR risk assessments that consider territory vulnerability.
