Zone du PLU of the municipality of Nouvion

The Urban Planning Code defines four types of areas regulated in the local planning plan (R.123-5 to 8): urban areas (U), areas to be urbanised (AU), agricultural areas (A) and natural and forest areas (N). These areas shall be demarcated on one or more graphic documents. A regulation is attached to each area. The by-law may lay down different rules, depending on whether the purpose of the construction relates to housing, hotel accommodation, offices, commerce, crafts, industry, agricultural or forestry operations or warehouse functions. These categories are limited (Art. R.123-9).The areas already urbanised where existing or under construction public facilities have sufficient capacity to serve the buildings to be installed are classified as U-areas.The natural areas of the municipality may be classified as AU zones, which are intended to be opened for urbanisation depending on whether or not the existing equipment on the periphery is sufficient to serve the buildings to be installed. There are two types of AU zone: “constructible” and “inconstructible” areas.Can be classified as zones A, the areas of the municipality, whether or not equipped, to be protected due to the agronomic, biological or economic potential of agricultural land.Can be classified as N zones, the areas of the municipality equipped or not, to be protected either by reason of the quality of the sites, natural habitats, landscapes and their interest, in particular from the aesthetic, historical or ecological point of view, either the existence of a forestry operation or their nature as natural areas.- Within the N zones, can be: perimeters in which possibilities for the transfer of the right to build can be carried out (transfer of COS),- areas of limited size and capacity where construction is possible under the condition of implantation and density.《城市规划法典》对本地规划方案中需管控的四类区域作出了规定（条款编号R.123-5至R.123-8）：城市建成区（U）、待城市化区域（AU）、农业区域（A）以及自然与森林区域（N）。上述四类区域需通过一份或多份图文文件予以划定，且每类区域均配套相应管控规则。本地配套法规可根据建设用途的差异制定差异化规则，建设用途涵盖住宅、酒店住宿、办公、商业、手工业、工业、农林作业及仓储功能。上述区域分类存在限定条件（详见条款R.123-9）。已完成城市化的区域，若其现有或在建的公共设施具备足够承载力以服务待建设建筑，则归类为U类区域。市域内的自然区域可归类为AU类区域，此类区域是否开放用于城市化建设，取决于其外围现有配套设施是否具备足够承载力以服务待建设建筑。AU类区域分为两类："可建设区域"与"不可建设区域"。市域内所有区域，无论是否已配套设施，若因农用地具备农艺、生物或经济价值而需要予以保护，则可归类为A类区域。市域内所有区域，无论是否已配套设施，若因以下任一情形需要予以保护，则可归类为N类区域：一是场地品质、自然生境、景观及其美学、历史或生态层面的价值；二是存在林业作业活动，或其本身属于自然区域。在N类区域范围内，还可细分为： - 可实施建筑权转让的边界区块（COS转让）； - 规模与承载力有限，仅在满足布局要求与密度限制的前提下方可开展建设的区域。
