Regulatory zones of the PPRI 2013 Dordogne and tributaries to Monceaux sur Dordogne — 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.

2013年多尔多涅河及其支流至多尔多涅河畔蒙索的自然洪水风险预防规划（PPRI）管控区——科雷兹省

科雷兹省利乌尔德尔境内阿尔让塔片区的多尔多涅流域及其支流自然洪水风险预防规划（PPRI），覆盖15个市镇。

自然洪水风险预防规划（以下简称自然PPR）依据《环境法典》第L.562-1条制定。在洪水风险暴露区域，规划将根据风险强度划定建设与设施禁止区，以避免加剧风险；对于可获批建设与设施的区域，则明确相应的实施要求。

本次多尔多涅流域及其支流从阿尔让塔至利乌尔德尔的PPRI规划于2013年10月30日获批，覆盖15个市镇，每个市镇对应一份PPRI规划。

涉及的河流包括多尔多涅河（Dordogne）、马罗讷河（Maronne）、苏维涅河（Souvigne）、萨涅河（Sagne）、菲莱尔河（Filèle）、马尔费尔热河（Malefarge）、梅努瓦尔河（Ménoire）以及塞鲁河（Cerou）。本次洪水风险基于数值模拟推演得出。

参考洪水事件选取标准为：苏维涅河、萨涅河与菲莱尔河采用有记录以来的最强历史洪水（1960年10月洪水）；多尔多涅河、马罗讷河、马尔费尔热河、梅努瓦尔河以及塞鲁克斯河（Céroux）则采用百年一遇计算洪水。本管控规则的核心目标为防范洪水对人员与财产造成的风险。据此，洪水风险区域按管控要求划分为三类：红色区域（不可建设）、深蓝色区域（可在满足经济活动相关条件下建设）以及蓝色区域（可在满足相关条件下建设）。

各对应市镇的PPRI规划分别为：多尔多涅河畔阿尔让塔、欧特法日、拉沙佩勒-圣若罗、福尔热、圣沙芒、多尔多涅河畔蒙索、巴西尼亚克勒巴、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、阿斯泰亚克以及利乌尔德尔。
