Simple download service (Atom) of the dataset: Brownfields and hollow teeth — census 2015 — 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 2015. 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.## 普查概况 自2009年起，马恩省领土事务总局对马恩省主要城区范围内的可用土地资源开展普查。本次普查涉及两类用地：其一为各类已知或疑似棕地（brownfields，涵盖工业、铁路、军事等类型）；其二为被至少2块建成地块环绕、被归类为“空心地块（hollow teeth）”的未开发空地。自2015年起，空心地块的纳入面积阈值为500平方米，棕地的纳入面积阈值为2000平方米。本次普查并非全面普查，且仅完成至2015年10月。 ## 普查溯源 首轮棕地普查依托法国生态、可持续发展与能源部旗下的污染场地名录数据库“BASIAS”与“Basol”开展。随后，省领土事务部门的属地专员（RT）赴现场踏勘，完成了首轮普查的补充完善。 根据省领土事务总局（DDT）采用的定义，本次识别的空心地块面积需大于400平方米（2015年起调整为500平方米）。位于待城市化区域（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平方米但城区占比（U）不足400平方米的土地，亦予以排除。随后，省领土事务部门的属地专员（RT）再次赴现场踏勘，进一步完善了首轮普查工作，且该普查仍非全面覆盖式普查。
