The PPRNP

The PPRNP in Val d'Isère

The Plan de Prévention des Risques Naturels Prévisibles (PPRNP) regulates land use according to the natural risks to which it is subject. These regulations, which are binding on urban planning documents, range from a ban on building to the possibility of building under certain conditions. The PPRNP is a document drawn up by the French government.

Mountain risk

By prefectoral decree no. 2022-0156 dated March 18, 2022, the following was approved:

modification no. 2 of the Val d'Isère Natural Risk Prevention Plan approved in 2006 and modification no. 1 of the general revision no. 2 of the PPRn approved in advance in 2018.

Henceforth, the PPRn applicable to the Val d'Isère municipality give priority to prescriptions in terms of means (constructive provisions) that enable the implementation of new technical solutions (resistant glazing, reinforced openings) that meet protection objectives.

However, certain constructional provisions, such as the prohibition of opening windows on the most exposed façades, subject to damaging forces or energies, remain prescribed.

A new insert recalls the local authority's prerogatives with regard to the instruction of town planning authorizations. It underlines the responsibility of the project owner in applying the measures, and the obligation to provide a certificate guaranteeing that the constraints have been properly taken into account in the project by a professional.

The documents relating to this modification are available below:

By a judgment dated December 22, 2020The Grenoble Administrative Court has annulled the order of April 30, 2018, which makes the draft revision no. 2 of the "Mountain Risks" section of the PPRN of the Val d'Isère commune immediately enforceable against sectors of the commune where foreseeable natural risks are identified as identical to or less than those assessed by the PPRN approved on April 27, 2006.

For parcels classified in the 2018 PPRN as presenting the same or lesser risk than that assessed in the 2006 PPRN, the 2006 PPRN applies.
For parcels classified in the 2018 PPRN as presenting a worsening of the risk to that assessed in the 2006 PPRN, the 2018 PPRN applies.

The most restrictive provisions of these two versions of the PPRN apply.
