Perimeter of the PPRN of the municipality of Fouras (Coastal coastal storms and sea submersion) in Charente-Maritime

This dataset contains the boundaries at the different stages of the development of the PPRN. 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 (natural) PPR; — scope of exposure to risks that corresponds to the perimeter regulated by the approved RPP. This approved perimeter is a public utility easement (PM1 for PPRNs); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集收录了PPRN发展不同阶段的边界信息。此类边界的特征为：其由官方文书产生，并自既定日期起生效。具体如下：——（自然）PPR规定令所载的法定边界；——经批准的RPP所规制的风险暴露范围；该经批准的边界属于公共设施地役权（PPRN对应PM1）；——研究范围，即开展危险性研究的包络范围。
