Dataset Direct Download Service (WFS): PPR Baliros (64DDTM20000003) — Information area of a Baliros Flood Prevention Plan (64091), 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规划（Plans for the prevention of natural hazards，简称PPRN），其为国家在风险防治领域的核心工具。本类规划的制定目标为对存在重大风险的区域内的开发活动实施监测。 PPRN由省长审批，具体执行工作通常由省领土事务局（departmental directorates of the territories，简称DDT）承担。此类规划通过禁止建设行为、对现有或新建建筑提出相关要求（含建设规范、减灾工程、农业使用限制或农业活动约束等），对土地利用方式进行规制。此类规划可处于编制（待审批）、预实施或已获批三种状态。 专家信息可用于阐明PPRN框架内开展的专业研判工作，具体方式包括明确特定要点（如断裂带、桥梁等障碍物），或补充有助于全面理解PPRN的相关信息（如洪水标记、水流方向、流速等）。
