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（PPRN），该计划是国家在风险预防领域的核心治理工具。本流程旨在对面临重大风险的区域的发展状况进行监测。 PPRN由省长（prefects）审议决定，通常由领土事务部门总局（DDT）负责具体实施。此类计划通过设定建筑禁令、对现有或未来建筑提出相关要求（含建设规范、降低脆弱性工程、限制农业使用方式或作业行为等），以此规范土地用途或开发活动。 此类计划可分为法定编制中、提前实施及已获批三类状态。 专家辅助信息可通过明确特定细节（如断裂带、桥梁类障碍物等），或补充有助于全面理解PPRN的实用资料（例如洪水标记、水流方向、流速等），来清晰阐释PPRN框架内开展的专业评估工作。
