Zone du PLU of the municipality of Saigneville

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）规定了地方规划方案中需规制的四类区域（R.123-5至R.123-8）：城市建成区（urban areas，U）、待城市化区域（areas to be urbanised，AU）、农业区域（agricultural areas，A）以及自然与林业区域（natural and forest areas，N）。上述四类区域需在一份或多份图件中完成划定，且每一类区域均配套专属管理规则。地方性法规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、农林作业或仓储功能，该类用途类别受R.123-9条限定。
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力以服务拟新建建筑，则划归为U类区域。
市域内的自然区域可划归为AU类区域，该类区域是否开放用于城市化开发，取决于其外围现有公共设施是否足以服务拟新建建筑。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，无论是否配套公共设施，若因农地的农艺、生物或经济价值而需要保护的，均可划归为A类区域。
市域内所有区域，无论是否配套公共设施，若因以下任一情形需要保护的，均可划归为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，可进一步细分为：
- 可进行建筑权转移的边界范围（COS转移）；
- 规模与承载力受限，仅在满足布局与密度要求的前提下方可开展建设的区域。
