PPR BAUDREIX (64DDTM20000004) — Information area of a Baudreix Flood Prevention Plan (64101), Pyrenees-Atlantiques department

Plans for the prevention of natural hazards (PPRN) were established by the Act of 2 February 1995 on strengthening the protection of the environment. They are the key instrument of the State in the field of risk prevention. The objective of this procedure is to monitor development in areas exposed to a major risk. The PPRNs are decided by the prefects and usually carried out by the departmental directorates of the territories (DDT). These plans regulate land use or use through prohibitions on construction or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on agricultural use or practices, etc.). These plans may be under development (prescribed), implemented in advance or approved. The expert information helps to shed light on the expertise conducted within the framework of the PPRN by specifying particular points (fracturing zone, obstacle like a bridge,...) or by adding useful information to the general understanding of the PPRN (e.g. flood markers, flow direction, flow velocity, etc.)1995年2月2日颁布的《加强环境保护法案》确立了自然灾害防治计划（Plans for the prevention of natural hazards，PPRN），此类计划是国家在风险防控领域的核心管控工具。本流程的目标是对存在重大风险的区域开发活动进行监测。 此类计划由省长审定，通常由领土部门局（departmental directorates of the territories，DDT）牵头落实。此类计划通过禁止建设、对既有或新建建筑提出要求（包括建设规范、减灾工程、农业使用限制或耕作规范等），对土地利用行为进行规制。 此类计划可分为编制中（已获批编制）、提前实施以及已获批三类状态。 专家信息可通过明确特定点位（如断裂带、桥梁等障碍物），或补充有助于全面理解PPRN的相关信息（如洪水标记、水流方向、流速等），来阐明PPRN框架内开展的专家研判工作。
