Dataset Direct Download Service (WFS): PPRN — Perimeter of the PSS of the municipality of VILLEY-LE-SEC (54583)

Right of way to areas affected by the regulatory zoning of submersible surface plans (PSS) of the department of Meurthe-et-Moselle. This perimeter, approved by Decree of 10 December 1976, is a public utility easement and is included in the PM1 easement. Submersible Surface Planes (PSS) are the first mapping documents regulating land cover in flooding areas for federal watercourses. They were created by the Decree-Law of 30 October 1935 and its implementing decree of 20 October 1937. The Barnier Law of 2 February 1995 gives PSS a risk prevention plan (PPR) status, making them enforceable against third parties. The PSS is a document that establishes a utility easement affecting land use. It allows the administration to oppose any action or work likely to impede the free flow of water or the conservation of flood fields (Article R425-21 of the Urban Code). The filing of a declaration before carrying out works likely to affect the natural flow of water (digues, embankments, depots, fences, plantations, constructions) is therefore necessary. Although having the same legal value, PSS and PPR are technically different. SSPs “merely” map a flood hazard in contrast to PPRs that represent a risk taking into account the vulnerability of the territories (regulatory zoning plan). Finally, the PSS mapped a so-called “average” flood less than the reference flood used as the basis for the development of PPRs (the highest known flood corresponding to the highest known waters (PHEC) and, in the event that it was lower than a centennial flood, the latter). Pursuant to Article L562-6 of the Code de l’Environnement, the PSS are to be PPR pending their repeal by a PPR on the municipalities concerned.默尔特-摩泽尔省受淹没地表规划（Submersible Surface Plans, PSS）监管区划影响区域的通行权。该范围经1976年12月10日政令批准，属于公共事业地役权，已纳入PM1地役权范畴。 淹没地表规划（PSS）是规范联邦水道洪泛区土地利用的首批制图文件，由1935年10月30日的法令法律及1937年10月20日的实施政令制定。 1995年2月2日的巴尼耶法案赋予PSS风险预防计划（Plan de Prévention des Risques, PPR）地位，使其具备对第三方的强制执行效力。PSS是确立影响土地使用的公共事业地役权的文件，允许行政部门反对任何可能阻碍水流自由流通或破坏洪泛区的行为或工程（《城市法典》第R425-21条）。因此，在开展可能影响自然水流的工程（如堤坝、路堤、堆场、围栏、造林、建筑工程等）前，需进行申报备案。 尽管PSS与PPR具有同等法律效力，但二者技术层面存在差异。PPR是综合考量领土脆弱性的风险监管区划规划，而PSS“仅”针对洪水风险进行制图。此外，PSS划定的是所谓“平均”洪水范围，其标准低于PPR编制所依据的参考洪水标准——参考洪水为已知历史最高水位（Plus Hautes Eaux Connues, PHEC），若该水位低于百年一遇洪水标准，则以百年一遇洪水作为参考。 根据《环境法典》第L562-6条规定，在相关市镇通过PPR废止现有PSS前，原PSS仍具有PPR的法律效力。
