Land diagnostics made through the intercommunal PLH, the Saint-Dizier PLU and the inventory of urban wastelands in the territory have highlighted the need to treat the abandoned areas of the territory. These brownfields can become land resources available for the territory of Saint-Dizier, in particular by offering an opportunity to recompose the urban fabric. At the same time, Saint-Dizier and in particular its city centre, encounters difficulties at the commercial level. This is partly caused by unsuitable commercial premises, in particular because of the small size of the available areas. To address this problem, the city has chosen to transform part of the downtown space by demolishing a set of unoccupied buildings constituting a wasteland. The land thus freed will allow the establishment of a global operation over the entire land tenure, combining commercial development, the creation of housing but also the development of public spaces. This operation is therefore perfectly in line with the objective of enhancing the attractiveness of Saint-Dizier, in particular by diversifying and densifying the commercial offer, reconnecting the various existing and newly formed spaces and creating qualitative and functional public and leisure spaces.
