Regulatory zones of PPRI 2013 Dordogne and tributaries in Liourdes — Corrèze

Plans for the prevention of natural flood risk PPRI of the Dordogne basin and its tributaries of Argentat in Liourdres (15 communes) in Corrèze

Natural PPRs are established in accordance with Article L. 562-1 of the Environmental Code. In exposed areas, depending on the intensity of the risk, they shall define the prohibition zones for constructions and installations in order not to aggravate the risk, or, in areas where constructions and installations may be authorised, the implementation requirements.

The PPRi of the Dordogne basin and its tributaries from Argentat to Liourdres, approved on 30/10/2013, cover 15 municipalities (one PPRi per municipality). The rivers concerned are Dordogne, Maronne, Souvigne and Sagne and Filèle, Malefarge, Ménoire and Cerou. The hazard is derived from a modeling. The reference flood is the strongest history known for Souvigne, Sagne and Fidèle (crue of October 1960) and the centennial flood calculated for Dordogne, Maronne, Malefarge, Ménoire and Céroux. The purpose of the regulations is to prevent the risk to people and property. For this purpose, the flood-free territory is classified as red (inconstructible), dark blue (constructable under conditions for economic activities) or blue (constructible under conditions)

A PPRi is established for each municipality, i.e.: Argentat-sur-Dordogne, Hautefage, La-Chapelle-Saint-Géraud, Forgès, Saint-Chamant, Monceaux-sur-Dordogne, Bassignac-le-Bas, Reygades, Chenaillers-Mascheix, Brivezac (merged with Beaulieu-sur-Dordogne), Beaulieu-sur-Dordogne, Nonards, Altillac, Astaillac and Liourdres.

多尔多涅河及其支流在利乌尔德尔——科雷兹省的2013年PPRI监管区域

科雷兹省利乌尔德尔地区阿日唐支流所在的多尔多涅河流域自然洪水风险预防计划（PPRI）方案（覆盖15个市镇）

自然洪水风险预防计划（PPRI）的制定需符合《环境法典》第L.562-1条之规定。在风险暴露区域，该计划将根据风险强度划定禁止建设与安装设施的区域，以避免加剧风险；或在可获批建设与安装设施的区域，明确相关实施要求。

本项针对多尔多涅河流域及其从阿日唐至利乌尔德尔的支流的PPRI方案于2013年10月30日获批，覆盖15个市镇（每个市镇对应一份PPRI方案）。涉及的河流包括多尔多涅河、马罗讷河、苏维涅河、萨涅河、菲莱尔河、马勒法尔热河、梅努瓦尔河以及塞鲁河。本次风险评估基于建模推演得出。参考洪水标准为：苏维涅河、萨涅河与菲德莱河采用有记录以来的最强历史洪水（1960年10月洪水事件），多尔多涅河、马罗讷河、马勒法尔热河、梅努瓦尔河以及塞鲁克斯河则采用百年一遇计算洪水。本监管方案的宗旨为防范对人员与财产的洪水风险。为此，无洪水威胁的区域被划分为三类：红色（不可建设）、深蓝色（符合条件可开展经济活动类建设）以及蓝色（符合条件可建设）。

每个市镇均对应一份PPRI方案，具体包括：多尔多涅河畔阿日唐、奥特法日、拉沙佩勒-圣热罗、福尔热、圣沙芒、多尔多涅河畔蒙索、下巴锡尼亚克、雷加德、谢奈耶-马谢、布里夫扎克（已与多尔多涅河畔博略合并）、多尔多涅河畔博略、诺纳尔、阿尔蒂亚克、阿斯蒂亚克以及利乌尔德尔。
