Regulated areas of the local planning plan of Lassur

The regulated zoning of the local planning plan (LDP) is digitised in accordance with the national requirements of the CNIG.
The Urban Planning Code defines four types of restricted areas in the 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.

地方规划计划（Local Planning Plan, LDP）中的管控区划已按照法国国家地理信息委员会（Commission nationale de l'information géographique, CNIG）的国家规范完成数字化。
《城市规划法典》在地方城市规划方案（Plan Local d'Urbanisme, PLU）中划定了四类管控区域（条款R.123-5至R.123-8）：城镇建成区（U）、待城镇化区域（AU）、农业区域（A）以及自然与森林区域（N）。上述区域需通过一份或多份图文文件进行划定，且每个区域均配套有相应管控规则。配套实施细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、农林作业或仓储功能等。上述区域分类均为限制性分类（条款R.123-9）。
已完成城镇化的区域将被划为U类区域，要求区域内现有或在建的公共设施具备足够承载力，可为后续拟建建筑提供服务。
本市镇管辖范围内拟开展城镇化开发的自然属性区域，可根据外围现有公共设施是否足够为后续拟建建筑提供服务，被划为AU类区域。AU类区域分为两类："可建设型"AU区域与"不可建设型"AU区域。
A类区域可被划为本市镇管辖范围内的保护区域，无论是否配套公共设施，其划定依据为农用地具备农艺、生态或经济价值潜力。
本市镇管辖范围内无论是否配套公共设施的区域，均可被划为N类保护区域，其保护依据包括场地品质、自然栖息地、景观风貌及其价值——尤其是美学、历史或生态层面的价值，以及存在林业资源或其本身属于自然区域的属性。在N类区域内部，可进一步划定以下子区域：
— 可开展建筑权转让的区域（Transfer of COS），
— 规模与承载力有限的区域，此类区域需符合选址与密度要求方可开展建设。
