The urban community is a public establishment for inter-municipal cooperation that brings together several municipalities in a single block and without an enclave that, on the date of its creation, form a group with a population of more than 250,000 and that join together within an area of solidarity to draw up and run a joint urban development and planning project for their territory. Where the urban community includes one or more priority neighbourhoods for urban policy, this joint project includes a section on social and urban cohesion, making it possible to define the guidelines for the urban community in terms of urban policy and strengthening solidarity between its member municipalities. It determines the ways in which the competences of the urban community contribute to the objectives of social and territorial cohesion.
These conditions are not required for urban communities existing on the date of publication of the loi n° 99-586 du 12 juillet 1999 relative au renforcement et à la simplification de la coopération intercommunale.
The creation of an urban community resulting from the merger of an urban community mentioned in the previous paragraph with one or more other public establishments for intercommunal cooperation is not subject to the population threshold set in the first paragraph.
The population threshold set in the first paragraph does not apply when the public establishment of intercommunal cooperation includes a commune that has lost the status of regional capital, when it exercises all the compulsory competences of the urban communities mentioned in Article L. 5215-20 and that its member municipalities deliberate under the majority conditions provided for in the first paragraph of II of article L. 5211-5 before 1 January 2020.
