About Communauté d'agglomération - Coeur d'Essonne
The Communauté d'agglomération Coeur d'Essonne Agglomération is a French public establishment for intercommunal cooperation (EPCI) with its own taxation authority, located in the Essonne department, in the Île-de-France region. This intercommunal structure emerged from the grouping of several communes in the southern part of the department, as part of successive reforms of the French intercommunal framework aimed at strengthening cooperation between local authorities and pooling certain public competencies.
The territory of Coeur d'Essonne Agglomération covers part of southwestern Essonne, bringing together several communes with varied profiles, ranging from dense urban areas to more suburban and rural spaces. This territorial diversity is one of the defining characteristics of the agglomeration, which must contend with differentiated local realities in terms of planning, demographics, and economic development. The agglomeration positions itself as an intermediate level of governance between member communes and departmental or regional authorities.
As an EPCI, Coeur d'Essonne Agglomération exercises competencies assigned to it by law or transferred by member communes, notably in the fields of economic development, spatial planning, housing, urban policy, as well as the management of certain facilities and public services of community interest. It also acts in the fields of environment, transport, and road infrastructure, thereby contributing to the coherence of public policies across its territory. Its action is rooted in a logic of territorial solidarity and pooling of resources among member communes, with the aim of improving services provided to residents within its perimeter.
The website coeuressonne.fr serves as the official institutional website of the Communauté d'agglomération, presenting its competencies, news, governing bodies, and the services offered to residents and member communes of the territory.
