Zone du PLU of the municipality of Saint Vaast en Chaussee

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.《城市规划法规（Urban Planning Code）》明确界定了地方规划方案中受规制的四类区域（条款编号R.123-5至R.123-8）：城市建成区（U，urban areas）、待城市化区域（AU，areas to be urbanised）、农业区域（A，agricultural areas）以及自然与森林区域（N，natural and forest areas）。上述区域须通过一份或多份规划图则完成界址划定。 每类区域均配套专属的规制细则。本附则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、农业、林业作业及仓储功能。此类用途类别受条款R.123-9的规制限定。 已完成城市化的区域，若其现有或在建公共设施具备足够承载能力，可为拟新建建筑物提供配套服务，则归类为U类区域。 市镇管辖范围内的自然区域可归类为AU类区域，该类区域是否开放城市化审批，取决于其周边现有配套设施是否足以服务拟建设的建筑物。AU类区域分为两类：可建设区域与不可建设区域。 市镇管辖范围内的所有区域，无论是否配备公共配套设施，若因其农地具备农艺、生物及经济潜力而需要加以保护，则可归类为A类区域。 市镇管辖范围内的所有区域，无论是否配备公共配套设施，若因以下任一情形需加以保护，则可归类为N类区域：一是场地品质、自然栖息地、景观及其固有价值（尤其在美学、历史或生态层面）；二是存在林业作业活动；三是其本身属于自然区域属性。 在N类区域范围内，可进一步划分为： - 可实施建筑权转让的边界范围（COS转让，transfer of COS）； - 规模与容量受限的区域，此类区域须满足选址与密度管控要求后方可开展建设。
