Simple download service (Atom) of the dataset: Perimeter of the PPR flooding of the Val d’Allier Clermontois (63DDT20110005) approved on 04/11/2013 — Puy-de-Dôme

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在开发各阶段的边界范围。此类边界范围的特性为：均由官方文书确立，并自指定日期起生效。具体包括以下三类： — 纳入PPR（自然类或技术类）审批指令中的法定范围； — 与经批准的RPP所规制范围相对应的风险暴露范围；该经核准的边界范围属于公共地役权范畴（PPRN对应PM1，PPRT对应PM3）； — 对应危险源研究覆盖包络的研究范畴。
