Simple download service (Atom) of the dataset: Perimeter of the PPRN of the municipality of La Rochelle in Charente-Maritime — Erosion and marine submersion.

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. This is the following: — prescribed scope contained in the prescription order of a PPR (natural); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集涵盖PPRN各开发阶段的边界。此类边界的核心特征为：系官方行为的法定产物，且自指定生效日期起产生相应效力。具体包含以下三类： —— 自然类PPR处置令所载明的法定范围； —— 与获批RPP所规制范围相对应的风险暴露范围，该获批边界属于公共用地役权（PPRN适用PM1）； —— 研究范围，即开展危险性研究所覆盖的边界区间。
