Map visualisation service (WMS) of the dataset: risk Perimetre PPRT Nitro-Bickford

This dataset contains the boundaries at the different stages of the development of the PPRT. The characteristic of such perimeters is to be the consequence of an official act and to produce their effects from a defined date. This is the following: — prescribed perimeter contained in the prescription order of a PPR (natural or technological); — scope of exposure to risks that corresponds to the perimeter regulated by the approved RPP. This approved perimeter is a public utility easement (PM3 for PPRTs); — scope of study which corresponds to the envelope in which the hazards were studied.
