PPR JATXOU (64DDTM20160010) — Linear information area of a Jatxou Flood Prevention Plan (64282), 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》确立了自然灾害防治计划（Plans for the prevention of natural hazards，PPRN），该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内的开发活动实施监测。 该类计划由省长审定，通常由省级领土事务总局（Departmental Directorates of the Territories，DDT）负责落实。此类计划通过禁止建设或对既有、拟建建筑提出相关要求（包括建设条款、减灾加固工程、农业使用限制或作业规范等），对土地利用活动进行规范。 此类计划可处于编制（法定编制）、预实施或已获批三种状态。 专家信息可通过明确特定要点（如断裂带、桥梁等障碍物），或补充有助于全面理解PPRN的实用信息（例如洪水标记、水流方向、流速等），来阐明PPRN框架下开展的专业工作。
