Dataset Direct Download Service (WFS): PPR Restricted Area Movements of Field in the commune of MONT DORE (63DDT20080005) approved on 22-12-2008 — Puy-de-Dôme

For natural PPRs, the Environmental Code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures can be foreseen to avoid exacerbating the risk. Depending on the hazard level, each area is subject to an enforceable settlement. The regulations generally distinguish three types of zones: 1- ‘Building prohibited areas’, known as ‘red areas’, where the hazard level is high and the general rule is the prohibition on construction; 2- ‘prescribed areas’, known as ‘blue zones’, where the hazard level is average and the projects are subject to requirements adapted to the type of issue; 3- areas not directly exposed to risks but where constructions, works, developments or farms, agricultural, forestry, craft, commercial or industrial could aggravate risks or cause new ones, subject to prohibitions or requirements (cf. Article L562-1 of the Environmental Code). The latter category applies only to natural RPPs. The PPR terrain movement of Mont-Dore defines 5 regulatory zones: — Zone R1 with high hazard and high vulnerability located on exit Clermont-Ferrand road city, is the only urbanised area in the commune of Mont-Dore located in the vault; it specifically concerns a section of the road to Clermont-Ferrand where is located about twenty individual houses threatened by blockfalls coming from the Angle cliff. — Zone R2 with high hazard and intermediate to low vulnerability concerns large areas unurbanised often located in the mountains in steep slopes or in areas of major spread of landslides, mudslides or mudslides or landslides. There are no constructions in these areas. — Zone B1 with medium and high vulnerability nevertheless remains constructable through the application of preventive measures — Zone B2 with medium and intermediate or low vulnerability nevertheless remains constructable through the application of preventive measures — Zone J is deemed to be low risk. This area is only concerned by recommendations for new constructions and extensions of more than 20 m²针对天然风险防范规划（PPR），法国《环境法典》第L562-1条划定了两类区域：风险暴露区，以及虽未直接面临风险但可采取措施避免风险加剧的区域。 根据危险等级的不同，每类区域均需遵循可强制执行的管控规则。相关法规通常将区域划分为三类： 1. **禁建区（红区）**：危险等级较高，通用管控规则为禁止建设； 2. **管控区（蓝区）**：危险等级中等，相关建设项目需遵循适配风险类型的管控要求； 3. 未直接面临风险，但各类建设、工程、开发活动或农、林、手工业、商业、工业场所可能加剧既有风险或引发新风险的区域，需遵守禁建或管控要求（详见《环境法典》第L562-1条）。该类区域仅适用于天然风险防范规划（PPR）。 蒙多勒（Mont-Dore）地区的滑坡风险防范规划（PPR）划定了5类管控区域： —— R1区：危险等级高且脆弱性强，位于克莱蒙费朗公路出城段，是蒙多勒市镇境内唯一一处位于滑坡拱体区域的城市化区域；该区域具体涵盖克莱蒙费朗公路的一段，沿线坐落着约20栋受安格尔悬崖落石威胁的独栋住宅。 —— R2区：危险等级高但脆弱性为中低水平，覆盖大片未城市化区域，通常位于山区陡坡地带，或是滑坡、泥流大规模发生的区域；该区域内无任何建设活动。 —— B1区：脆弱性为中高水平，但通过落实预防性管控措施仍可进行建设； —— B2区：脆弱性为中低或低水平，通过落实预防性管控措施仍可进行建设； —— J区：被认定为低风险区域，该区域仅针对面积超过20平方米的新建建筑及扩建项目提出管控建议。
