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（Meurthe-et-Moselle）辖区内，受淹没地表规划（Submersible Surface Plans，PSS）监管分区的通行权。该范围经1976年12月10日政令核准，属于公共事业地役权范畴，且被纳入PM1地役权体系。 淹没地表规划（PSS）是规范联邦水道洪泛区土地覆盖的首批测绘文件，其制定依据为1935年10月30日政令法及1937年10月20日配套实施政令。 1995年2月2日的巴尼耶法赋予PSS风险预防规划（Risk Prevention Plan，PPR）的法律地位，使其可对第三方产生强制约束力。PSS作为确立土地使用相关地役权的文件，允许行政部门反对任何可能阻碍水体自由流通或洪泛区保护的行为或工程（详见《城市法典》R425-21条）。因此，开展可能影响水体自然流通的工程（如堤坝、路堤、堆场、围栏、种植、建筑等）前，必须进行申报备案。 尽管PSS与PPR具有同等法律效力，但二者在技术层面存在差异：PPR需结合辖区脆弱性评估风险（属于监管分区规划），而PSS仅“单纯”划定洪灾风险范围。此外，PSS所划定的为所谓“中等”洪水范围，其基准低于PPR编制所采用的参考洪水标准——后者以最高已知水位（Plus Haute Eau Connue，PHEC）为依据，若该水位低于百年一遇洪水标准，则以百年一遇洪水为准。 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应暂代PPR执行。
