Simple download service (Atom) of the dataset: Natural flood risk prevention plan — Tarn Sector Communes — 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. This is the following: — prescribed scope contained in the prescription order of a PPR (natural or technological); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs and PM3 for PPRTs); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集涵盖PPRN发展各阶段的边界信息。此类边界的核心特征为：均由官方文书所确立，并自指定日期起产生法定效力。具体分类如下： —— 自然类或技术类PPR审批指令中载明的法定适用范围； —— 与经核准的RPP所规制范围相对应的风险暴露范围，该核准边界属于公用设施地役权（PPRN对应PM1，PPRT对应PM3）； —— 研究范畴，即开展危险源研究所覆盖的包络范围。
