Map Viewing Service (WMS) of the dataset: PPR Uzos (64DDTM20050017) — Information area of a risk prevention plan Uzos flood (64550), 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规划（Plans for the Prevention of Natural Hazards，以下简称PPRN），该规划是国家在风险防治领域的核心工具。 本流程的目标是对面临重大风险区域的开发活动进行监测。PPRN由省长审定，通常由领土事务省级总局（Departmental Directorates of the Territories，以下简称DDT）牵头落实。此类规划通过颁布建筑禁令、对既有或新建建筑提出要求（包括施工规范、减灾工程、农业使用或耕作方式限制等），对土地利用行为进行规制。此类规划可处于编制（报批）、预实施或获批状态。 专家信息可通过明确特定要点（如断裂带、桥梁等障碍物），或补充有助于深化对PPRN理解的实用信息（例如洪水标记、水流方向、流速等），来阐明PPRN框架内开展的专家论证工作。
