Map Viewing Service (WMS) of the dataset: PPRN — Perimeter of the PSS of the municipality of Bainville-AUX-MIROIRS (54042)

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）淹没地表规划（Submersible Surface Plans，简称PSS）所划定的管制区划涉及区域的公共役权。该范围经1976年12月10日政令批准，属于公共役权范畴，并被纳入PM1役权体系。 淹没地表规划（PSS）是首部针对国家级河道洪泛区土地覆盖进行管制的测绘文件，由1935年10月30日的政令法及其1937年10月20日的实施政令确立。 1995年2月2日的《巴尼耶法案》（Barnier Law）赋予PSS风险预防计划（Risk Prevention Plan，简称PPR）的法律地位，使其具备对第三方的强制执行效力。PSS是一类确立土地使用相关役权的文件，依据《城市法典》（Urban Code）第R425-21条，其允许行政主管部门反对任何可能阻碍水体自由流通或破坏洪泛区的行为与工程。因此，在开展可能影响水体自然流通的工程（如堤坝、路堤、仓库、围栏、种植园、建筑等）前，必须履行申报程序。 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是兼顾辖区脆弱性的风险管制规划（管制区划规划），而PSS仅对洪水风险进行测绘。此外，PSS所划定的所谓“平均”洪水水位低于PPR编制所依据的参考洪水水位：参考洪水水位指对应已知最高水位（PHEC，全称highest known waters）的已知最大洪水；若该洪水水位低于百年一遇洪水（centennial flood）水位，则以百年一遇洪水作为参考标准。 根据《环境法典》（Code de l’Environnement）第L562-6条规定，在相关市镇通过PPR废止PSS之前，PSS应视同PPR执行。
