Dataset Direct Download Service (WFS): PPR Bassussarry (64DDTM20080016) — Information area of a risk prevention plan Inondation of Bassussarry (64100), department of Pyrénées-Atlantiques.

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日发布的《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，缩写PPRN），该计划是国家在风险预防领域的核心管控工具。本类计划的实施目标是对存在重大风险区域的开发活动进行动态监测。 PPRN由行政长官审议决定，通常由领土部门管理局（departmental directorates of the territories，缩写DDT）负责组织实施。此类计划通过施工禁令、针对现有或在建建筑的管控要求（包括建筑规范、降脆弱性工程、农业使用限制或作业规范等），对土地利用行为进行规范。 此类计划可处于编制阶段（即规定性编制）、提前实施或已获批状态。 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（例如洪水标识、水流方向、流速等），来阐明PPRN框架下开展的专业评估工作。
