Dataset Direct Download Service (WFS): PPR ASCARAT (64DDTM20160003) — Information area of a risk prevention plan Inondation of ASCARAT (64066), 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）。该计划是国家在风险防范领域的核心工具，本流程旨在对面临重大风险的区域内的开发活动进行监测。 PPRN由省长审定，通常由领土事务省局（DDT）负责执行。此类计划通过建筑禁令或针对现有、未来建筑的相关要求（包括建筑规范、降脆弱性工程、农业使用或作业限制等），对土地使用行为进行规制。 此类计划可处于编制筹备、预实施或获批状态。 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的相关内容（例如洪水标记、水流方向、流速等），阐明该计划框架内开展的专业评估工作。
