Zone du PLU of the municipality of Arrest

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》（Urban Planning Code）界定了地方规划方案中规制的四类区域（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）。前述区域需在一份或多份图件中划定，每类区域均附有相应规制规则。本附则可根据建设用途的不同制定差异化规则，建设用途涵盖住宅、酒店住宿、办公、商业、手工业、工业、农业或林业作业以及仓储功能。此类用途类别受条款R.123-9约束。
已实现城市化，且现有或在建公共设施具备足够服务能力以覆盖拟建设建筑的区域，将被归类为U类区域。
市镇范围内的自然区域可被归类为AU区域，此类区域是否开放城市化建设，取决于其外围现有配套设施是否足以覆盖拟建设的建筑。AU区域分为两类：“可建设区域”与“不可建设区域”。
市镇范围内因农业用地具备农艺、生物及经济潜力而需要予以保护的区域，无论是否配有配套设施，均可被归类为A类区域。
市镇范围内无论是否配有配套设施，因以下任一情形需要予以保护的区域，均可被归类为N类区域：一是场地质量、自然栖息地、景观及其美学、历史或生态价值；二是存在林业作业活动，或其本身属于自然区域。
在N类区域内，可进一步划分为：
- 可实施建筑权转让的片区（transfer of COS）；
- 面积与容量受限的区域，此类区域可在满足布局与密度要求的前提下开展建设。
