Dataset Direct Download Service (WFS): Regulated areas of local urban planning and land use plans in Ariège

This dataset includes the assembly of the regulated zoning of the local planning plans (LDPs) and land use plans (POS) of Ariège as of 2 October 2021. These regulated zonings have been digitised in accordance with the national requirements of the CNIG. The Urban Planning Code defines four types of restricted areas in a PLU (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 restrictive (Art. R.123-9). Areas already urbanised are classified as U areas where existing or under construction public facilities have sufficient capacity to serve the buildings to be installed. The areas of a natural nature of the municipality intended to be opened for urbanisation depending on whether or not the existing facilities on the periphery are sufficient to serve the buildings to be installed may be classified as AU zones. There are two types of AU zone: “constructible” and “inconstructible” AU zones. Areas A may be classified as areas of the municipality, whether or not equipped, to be protected due to the agronomic, organic or economic potential of agricultural land. Areas of the municipality equipped or not may be classified as N zones, 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, the existence of forestry or their nature as natural areas. Within zones N, may be demarcated: — areas within which possibilities for the transfer of the right to be built may be carried out (transfer of COS), — areas of limited size and capacity where construction is possible under siting and density conditions. In a land use plan there are two main types of restricted areas: urban areas (U) and natural 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. Zones U and N are themselves divided according to existing or future developments. Thus in urban areas: — the UA areas indicate ancient urbanisation and dense tissue; — the UB areas a recent urbanisation with mainly collective housing; — UC areas a recent urbanisation but with pavilion habitat; — the UJ zones the various areas of activity of the municipality. With regard to natural areas: — the NA areas are referred to as future urbanisation, i.e. they can be developed at a later stage; — NB areas are natural areas partially serviced by equipment and in which constructions exist, but no further development is planned; — NC zones represent natural areas protected because of the agricultural value of the land or the richness of the soil or/or subsoil; finally, the ND areas are natural areas to protect either the quality of the sites or because there are nuisances or risks.本数据集收录了截至2021年10月2日的阿列日省（Ariège）地方规划方案（Local Planning Plans, LDPs）与土地使用规划（Plan d'Occupation des Sols, POS）中管制区划的汇编内容。上述管制区划已按照法国国家地理信息委员会（Commission nationale de l'information géographique, CNIG）的全国性规范完成数字化处理。 《城市规划法典》（Urban Planning Code）将地方城市规划方案（Plan Local d'Urbanisme, PLU）中的管制区划分为四类（条款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）以及自然与森林区域（natural and forest areas, N）。上述四类区划需通过一份或多份图文文件进行划定，且每个区划均配套相应的管制规则。管制细则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（条款R.123-9）。 已完成城市化的区域将被归类为U类区域，前提是现有或在建的公共设施具备足够承载力，可为拟建建筑提供配套服务。 市政范围内具备自然属性的区域，若其周边现有公共设施足以服务拟建建筑，则可被划定为AU类区域。AU类区域分为两类："constructible"（可建设）与"inconstructible"（不可建设）待城市化区域。 A类区域可被归类为市政农业区域，无论是否配套公共设施，均可因农用地的农艺、有机或经济潜力而受到保护。 市政区域无论是否配套公共设施，均可被归类为N类区域，其保护依据包括场地品质、自然栖息地、景观及其美学、历史或生态价值，以及林业资源存在的必要性或其天然属性。在N类区域范围内，可进一步划定：—— 可开展建设权转移的区域（transfer of COS），—— 规模与承载力受限的区域，此类区域需满足选址与密度条件方可开展建设。 土地使用规划中的管制区划主要分为两类：城市建成区（U）与自然区域（N）。上述区域需通过一份或多份图文文件划定，且每个区域均配套相应的管制规则。管制细则可根据建设用途制定差异化规则，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。 U类与N类区域可根据现有或未来开发情况进一步细分。 具体而言，城市建成区可细分为：—— UA类区域代表早期城市化形成的高密度建成肌理；—— UB类区域代表近期城市化区域，以集体住宅为主；—— UC类区域为近期城市化区域，但以独栋住宅为主；—— UJ类区域代表市政范围内各类活动用地。 关于自然区域：—— NA类区域被列为待未来城市化区域，即可在后续阶段进行开发；—— NB类区域为部分配套公共设施的自然区域，该区域内已存在建筑，但无进一步开发计划；—— NC类区域代表因土地农业价值或土壤/地下层资源丰度而受保护的自然区域；最后，ND类区域为需予以保护的自然区域，保护依据为场地品质，或为规避妨害与风险。
