Zone du PLU of the municipality of Boismont

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》明确了本地规划方案中受监管的四类区域（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）以及自然与林业区域（N）。上述区域需通过一份或多份规划图纸划定边界。每类区域均附有专属监管规则。本附属法规可针对不同建设用途制定差异化监管规则，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。上述用途分类受限于条款R.123-9。
已完成城市化改造，且现有或在建公共设施具备足够承载能力以服务拟建建筑的区域，归类为U类区域。
市镇范围内的自然区域可归类为AU区，此类区域是否开放城市化改造，取决于其周边现有配套设施是否足以服务拟建建筑。AU区分为两类：“可建设区域”与“不可建设区域”。
因农地具备农艺、生物或经济潜力而需要予以保护的市镇区域（无论是否配套设施），可归类为A类区域。
因场地品质、自然栖息地、景观及其美学、历史或生态层面的价值，或因存在林业作业、其本身属于自然区域属性而需要予以保护的市镇区域（无论是否配套设施），可归类为N类区域。
在N类区域内，可进一步划分为：
- 可开展建筑权转让的边界区域（COS），
- 规模与容量受限的区域，此类区域需满足建设选址与开发强度要求方可开展建设。
