Perimeter of the natural risk prevention plan of Chatillon-sur-Cluses (Haute-Savoie) — approved on 28/06/2004

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在不同发展阶段的边界范围。此类边界的特征为其源于官方行为，且自指定日期起生效，具体如下： —— 天然或技术类PPR的法定指令所包含的法定范围； —— 对应经核准RPP所规制范畴的风险暴露范围，该核准后的边界为公用役地（PPRN对应PM1，PPRT对应PM3）； —— 对应危害研究所涉包络范围的研究范畴。
