Simple download service (Atom) of the dataset: Brownfields and hollow teeth — census 2016 — in the department of Marne

Description: Since 2009, the departmental directorate of the Marne territories has been carrying out a census of the land resources available within the main urban areas of the Marne. This census concerns land rights of way corresponding on the one hand to known or probable brownfields of all types (industrial, railway, military, etc.) and on the other hand to unbuilt spaces surrounded by built plots (at least 2) qualified as hollow teeth. The area retained for hollow teeth since 2015 is 500 m² and that of brownfields 2 000 m² This census is not exhaustive. Census conducted until October 2016. Genealogy: A first census of brownfields was carried out from databases of the Ministry of Ecology, Sustainable Development and Energy “BASIAS” and “Basol”, listing polluted sites. Visits by the territorial referents (RT) of the departmental directorate of the territories were then carried out on site and made it possible to complete the first census. According to the definition adopted by the DDT, the hollow teeth identified have an area greater than 400 m² (500 m² since 2015). Hollow teeth located in areas AU (area to be urbanised) and N (natural and forested) or enclaved with no service, were not retained. Land of more than 400 m² with an area U (urban area) of less than 400 m² is excluded. Visits by the territorial referents (RT) of the departmental directorate of the territories were then carried out on site and made it possible to complete the first census, which is not exhaustive.描述： 自2009年起，马恩省领土事务局针对马恩省主要城区范围内的可用土地资源开展普查工作。本次普查涵盖两类与通行权相关的土地：其一为各类已知或疑似棕地（brownfields，涵盖工业、铁路、军事等多种类型），其二为被至少2宗建成地块环绕的未开发空地，即被归类为城市空心地块（hollow teeth）的区域。自2015年起，城市空心地块的认定门槛面积调整为500平方米，棕地的认定门槛面积则为2000平方米。 本次普查并非全面穷尽式普查，其完成时限为2016年10月。 普查溯源： 首批棕地普查工作依托法国生态、可持续发展与能源部的"BASIAS"与"Basol"污染场地名录数据库启动。随后马恩省领土事务局的领土事务专员（RT）赴现场开展实地核查，完善了首轮普查成果。 根据马恩省领土管理局（DDT）制定的认定标准，本次纳入普查的城市空心地块面积需大于400平方米（2015年起调整为500平方米）。位于待开发区（AU）、自然林区（N）或无配套设施的飞地内的空心地块均不予纳入；面积超过400平方米，但其中城区面积（U）不足400平方米的土地亦被排除。随后马恩省领土事务局的领土事务专员（RT）再次赴现场核查，进一步完善了首轮普查成果，且该普查并非全面穷尽式普查。
