Saint Viance PPRMT Regulatory Areas 2009 — Corrèze

Plan for the Prevention of Natural Risks of Field Movements (PPRMT) in the northwest sector of the commune of Saint-Viance (in Corrèze)

Natural PPRs are established in accordance with the provisions of Article L. 562-1 of the Environmental Code. The regulatory mapping translates into a geographical demarcation of the territory concerned by the risk. This delimitation defines areas in which specific regulations apply. These by-laws are valid as easement. As such, depending on the intensity of the hazard, they regulate the use of the land or its use by demarcating areas where new constructions and installations are prohibited in order not to aggravate the risk, and areas where constructions and installations may be authorised subject to compliance with requirements.

The PPRMT on the northwest sector of the commune of Saint-Viance was approved on 3 November 2009. After several disturbances related to soil instability, the hazards were analysed according to the geological formations in the presence, hydrogeology, and morphology. Depending on the intensity of the hazard and the present challenges, three areas have been defined: a medium hazard zone, classified as a blue zone (built subject to compliance); a strong hazard area with stakes, classified as an urbanable orange zone only for individual housing and the open-air hotel industry subject to compliance with requirements and a strong hazard area with no stakes classified as an inconstructible area.

2009年圣维昂斯（Saint Viance）PPRMT监管区域——科雷兹省（Corrèze）

科雷兹省圣维昂斯市镇西北部区域的地表移动自然灾害防治规划（Plan for the Prevention of Natural Risks of Field Movements，简称PPRMT）

自然风险防治规划（Natural PPRs）的制定需符合《环境法典》第L.562-1条的相关规定。监管测绘成果体现为受风险影响的领土范围的地理划界，该划界明确了适用特定监管要求的区域范围。此类附属法规以地役权形式生效，据此根据灾害强度等级管控土地利用：划定禁止新建建筑与设施的区域以避免加剧灾害风险，同时划定经合规审查后可批准建设与设施布设的区域。

本次圣维昂斯市镇西北部区域的PPRMT于2009年11月3日获批。在发生多起土壤失稳相关灾害事件后，技术团队结合现存地质构造、水文地质条件与地形地貌开展了灾害风险分析。基于灾害强度与当前防控挑战，本次规划划定了三类风险区域：中等风险区，归类为蓝色区域（需经合规审查后方可开展建设）；带管控阈值的高风险区，归类为仅可用于个人住宅与露天酒店业的可建设橙色区域，需满足相关合规要求；无管控阈值的高风险区，归类为不可建设区域。
