Dataset Direct Download Service (WFS): Regulatory zoning of the Flood Risk Prevention Plan (PPRI) in the municipality of Gassin (Var)

The Risk Prevention Plans (P.P.R) codified in Articles L562-1 to L562-7 and R562-1 et seq. of the Environmental Code, relating to the prevention of foreseeable natural hazards, the implementation of which is governed by Decree No 95-1089 of 5 October 1995, constitute one of the tools for the implementation of the State policy on flood prevention, which was redefined in the Interministerial Committee of 24 January 1994. This legislative and regulatory framework was supplemented by the Act of 30 July 2003. The Plan for the Prevention of Natural Flood Risks in the municipality of Gassin, linked to the presence of the Bourrian and Bélieu rivers, was approved by prefectural decree of 30 December 2005. A regulation shall apply referring to prohibition and/or prescription measures depending on the different mapped areas. The mapping of the hazard (allowing the development of regulatory zoning) was defined on the basis of mathematical modelling of flow in centennial flood from a photogrammetry at the scale of 1/5000e. As a result, a paper-based mapping was provided. This hazard allowed, following the application of a constructibility grid, to determine a digitalised regulatory zoning that was reported on a background IGN1998©EDR 25. A separate mapinfo table existed for each type of zoning: R1, R2, B1 and B2. These 4 tables were then merged to create a single table.
