Simple download service (Atom) of the dataset: PPRI Loire downstream in the Nantes agglomeration: Reference flood rating not altimeter 1 cm, in Loire-Atlantique
Description
The flood risk prevention plan (PPRI) of the Loire downstream 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 1 cm step on the Loire section between Nantes-St-Sébastien and Couëron-Le Pellerin.
