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）监管区划所覆盖的淹没区域通行权。该范围经1976年12月10日政令批准，属于公共事业地役权，且纳入PM1地役权范畴。 淹没地表平面规划（Submersible Surface Planes, PSS）是规范联邦水道泛滥区土地覆盖的首批测绘文件，其制定依据为1935年10月30日的法令及1937年10月20日的实施政令。 1995年2月2日颁布的《巴尼耶法案》赋予PSS风险预防规划（PPR）的法律地位，使其具备对第三方的强制约束力。PSS是一类确立影响土地使用的公共事业地役权的文件，可授权行政主管部门反对任何可能阻碍水体自由流通或滞洪区保护的行为与工程（详见《城市法典》第R425-21条）。因此，在开展可能影响水体自然流通的工程（如堤坝、路堤、堆场、围栏、种植工程、建筑工程等）前，需完成申报备案。 尽管PSS与PPR具有同等法律效力，但二者在技术层面存在显著差异。PPR是综合考量领土脆弱性的风险监管区划规划，而PSS“仅”针对洪涝风险绘制灾害分布范围。此外，PSS划定的所谓“平均”洪水水位低于作为PPR制定依据的参考洪水水位：参考洪水水位取历史最高已知水位（PHEC，即历史最高洪水），若该水位低于百年一遇洪水水位，则以百年一遇洪水作为参考标准。 根据《环境法典》第L562-6条规定，在相关市镇通过PPR废止PSS之前，PSS将视同PPR执行。
