Areas of the PLU (doc. 22.05.2006) in the municipality of Saint-Michel-de-Volangis

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）》明确了本地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（urban areas，缩写U）、待城市化区域（areas to be urbanised，缩写AU）、农业区域（agricultural areas，缩写A）以及自然与林业区域（natural and forest areas，缩写N）。上述四类区域需通过一份或多份规划图纸进行划定。每类区域均附带一项规制细则，配套法规可根据建设用途的不同制定差异化规则，建设用途包括住宅、酒店住宿、办公、商业、手工业、工业、农林作业或仓储功能。上述分类范围有限定（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为待建设筑物提供服务，则归类为城市建成区（U类区域）。 本市行政区域内的自然区域可归类为待城市化区域（AU类区域），此类区域是否开放开展城市化建设，取决于其周边现有配套设施是否足以服务待建设筑物。AU类区域分为两类：可建设区域与不可建设区域。 本市行政区域内，凡因农地的农学、生物学或经济价值潜力而需要予以保护的区域（无论是否配备相关设施），均可归类为农业区域（A类区域）。 本市行政区域内，凡因场地品质、自然栖息地、景观及其美学、历史或生态层面的保护价值，或因存在林业作业活动，或因其天然区域的固有属性而需要予以保护的区域（无论是否配备相关设施），均可归类为自然与林业区域（N类区域）。 - 在自然与林业区域（N类区域）内，可划分出两类区域：一是可开展建筑权转移的边界区块（建筑权转移（COS））； - 二是规模与承载力有限，仅在符合建设布局与开发密度要求的前提下方可开展建设的区域。
