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. For natural PPRs, the Environmental Code defines two categories of zones (L562-1): risk-exposed areas and areas that are not directly exposed to risks but where measures can be foreseen to avoid exacerbating the risk. Depending on the hazard level, each area is subject to an enforceable settlement. The regulations generally distinguish three types of zones: 1- ‘Building prohibited areas’, known as ‘red areas’, where the hazard level is high and the general rule is the prohibition on construction; 2- ‘prescribed areas’, known as ‘blue zones’, where the hazard level is average and the projects are subject to requirements adapted to the type of issue; 3- areas not directly exposed to risks but where constructions, works, developments or farms, agricultural, forestry, craft, commercial or industrial could aggravate risks or cause new ones, subject to prohibitions or requirements (cf. Article L562-1 of the Environmental Code). The latter category applies only to natural RPPs.淹没区地表测绘图（Submersible Surface Planes，PSS）是首部针对联邦水道洪泛区土地覆盖的规制性测绘文件。其制定依据为1935年10月30日的政令法律及1937年10月20日的实施政令。 1995年2月2日出台的巴尼耶法案赋予PSS风险预防计划（Risk Prevention Plan，PPR）法定地位，使其可对第三方强制执行。PSS是一类设定土地用益役权的文件，允许行政主管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与工程（《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（包括堤坝、路堤、堆场、围栏、种植作业及建筑工程等）前，必须提交工程申报。 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。风险预防计划（PPR）是综合考量领土脆弱性的风险规制区划计划，而PSS仅用于绘制洪灾风险分布图。此外，PSS划定的所谓“平均”洪水位，低于作为PPR制定依据的参考洪水位——即对应已知最高水位的历史最大洪水（PHEC）；若已知最高水位低于百年一遇洪水标准，则以百年一遇洪水作为参考基准。 根据《环境法典》第L562-6条规定，在相关市政辖区出台PPR取代PSS之前，PSS应视同PPR执行。 对于天然PPR，《环境法典》将其区划分为两类（L562-1）：风险暴露区，以及虽未直接暴露于风险但可采取措施避免风险加剧的区域。 依据灾害等级，每类区域均需执行可强制执行的规制方案。相关法规通常区分三类区域： 1. “禁止建设区”（又称“红色区域”）：灾害等级较高，原则上禁止任何建设活动； 2. “规制建设区”（又称“蓝色区域”）：灾害等级中等，相关工程需符合针对具体问题制定的适配性要求； 3. 虽未直接暴露于风险，但建设、工程、开发活动或农、林、手工、商业、工业经营行为可能加剧风险或引发新风险的区域，需遵守相关禁令或规制要求（参见《环境法典》第L562-1条）。该第三类区域仅适用于天然PPR。
