Simple download service (Atom) of the dataset: PPRI Loire downstream in the Nantes agglomeration: Reference flood rating not altimeter 5 cm, in Loire-Atlantique
Description
The Flood Risk Prevention Plan (PPRI) of the Loire downstream in the Nantes agglomeration replaces the PSS (Plan des Surfaces Submersibles) of the Loire Valley delimited by decree of 6 November 1958. Its purpose is to regulate land use (planning, construction and management rules) in the flood zone envelope modelled on the scenario of a 100-year flood (each year, one per cent chance for this type of flood to occur). The layer L_PPRI_LOIREAV_ISOC5CM_L_044.TAB presents the NGF-IGN69 level reached by the Loire for this reference centennial flood. The values are given by step of 5 cm on the Loire section between Nantes-St-Sébastien and Couëron-Le Pellerin.
