About Communauté d'agglomération - Grand Paris Sud Seine Essonne Sénart
The Communauté d'agglomération Grand Paris Sud Seine Essonne Sénart is a French public inter-municipal cooperation body (EPCI) with its own taxation powers, operating under the status of a "communauté d'agglomération". It was formed through the merger of several pre-existing inter-municipal structures, bringing together territories located south of the Paris region. Its administrative seat is located in Évry-Courcouronnes, in the Essonne department.
The territory covered by the authority spans a number of municipalities located mainly in the Essonne department, with a few additional municipalities attached in Seine-et-Marne, making it one of the largest inter-municipal groupings in the Île-de-France region in terms of population and area. This geographical configuration, straddling two departments, results from the combination of former distinct agglomeration areas, each of which retained a strong local identity, particularly around the historic urban centers of Évry, Corbeil-Essonnes, and Sénart. The resulting area combines dense urban zones, residential sectors, and preserved agricultural or natural spaces.
As an inter-municipal body, Grand Paris Sud Seine Essonne Sénart exercises shared responsibilities on behalf of its member municipalities. It is involved in areas such as economic development, spatial planning at the community level, housing, urban policy, local transport, waste management, water and sanitation services, as well as environmental protection. It also contributes to the drafting of urban planning documents and participates in structuring public infrastructure projects for the entire territory. Its role fits within a broader logic of coordinating local public policies, aiming to organize territorial development at a supra-municipal scale while respecting the individual competencies of member municipalities.
The website grandparissud.fr serves as the institutional website of the authority, presenting its areas of responsibility, administrative organization, news updates, and practical information intended for residents and local stakeholders.
