Natural Risk Prevention Plan — Perimeter — Department of Tarn-et-Garonne

This dataset contains the boundaries at the different stages of the development of the PPRN. The characteristic of these perimeters is to be the consequence of an official act and to produce their effects from a specified date. These are:
1 — prescribed scope in the prescription order of a PPR (natural or technological);
— 2 — scope of exposure to risks that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs and PM3 for PPRTs);
— 3 — scope of study which corresponds to the envelope in which the hazards were studied.
