Perimeter of the plan for the prevention of natural hazards of Veyrier-du-Lac (Haute-Savoie) — approved on 25/08/2010

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.本数据集收录了PPRN在不同发展阶段的边界范围。此类边界的核心特征为：其源于官方法定行为，且自指定日期起产生效力。具体如下： —— 自然类或技术类PPR的法定指令中载明的规定范围； —— 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对应PM1，PPRT对应PM3； —— 对应风险隐患研究覆盖范围的研究范畴。
