Map Viewing Service (WMS) of the dataset: Utility easement PM1 (base) on the Department of Vienna

Pursuant to Articles L. 562-1 et seq. of the Environmental Code, plans for the prevention of natural hazards (PPRN) and plans for the prevention of mine risks (PPRM) delimit: — areas exposed to risks in which construction, works, developments and operations are prohibited or subject to conditions; — areas not directly exposed to the risks in which constructions, works, developments and operations are prohibited or subject to conditions because they are likely to aggravate the risks or cause new ones The regulated zoning of PPRN-PPRM thus constitute the generators (as well as plates confused with generators) of the PM1 easements. This resource describes the plates of easements PM1依据《环境法典》第L.562-1条及后续条款，自然风险预防规划（PPRN，Natural Hazards Prevention Plans）与矿山风险预防规划（PPRM，Mine Risks Prevention Plans）划定两类区域： — 受风险影响区域：该区域内的建设工程、施工活动、开发项目与作业行为均被禁止，或需满足特定条件后方可开展； — 非直接受风险影响区域：该区域内的前述活动同样被禁止或需满足特定条件，因此类活动可能加剧既有风险或引发新的风险。 PPRN-PPRM的法定分区由此成为PM1地役权（PM1 easements）的生成依据，同时涵盖易与该生成依据混淆的相关图件。本数据集即对PM1地役权相关图件进行详细说明。
