The opening of line 15 Sud in the 4th quarter of 2026, interconnecting with RER C, will improve accessibility to the Issy station district, a densely populated area of 34,000 inhabitants and 27,000 salaried jobs, almost entirely located in Issy-les-Moulineaux and to a lesser extent in Clamart to the south-west. Since 2010, housing deliveries in the ZAC des Chartreux, Fort d'Issy and Bords de Seine districts have contributed to a 13% increase in population. The project dynamic continues with the ongoing delivery of the ZAC Léon Blum, where more than 2,200 homes are planned, 35% of which will be social housing. Marked by the Plateau de Clamart hillside, the Seine and Île Saint-Germain, the district boasts a remarkable landscape and vast views of the Greater Paris region. Sports facilities are particularly well-developed, especially since development projects have led to the construction and renovation of numerous facilities.
Launched in 2013, the Observatoire des quartiers de gare du Grand Paris Express is a partnership tool that brings together the Atelier parisien d'urbanisme (Apur), the Société des grands projets (SGP), the Direction régionale et interdépartementale de l'environnement, de l'aménagement et des transports (DRIEAT) and the Institut national de la statistique et des études économiques (Insee) as well as the Établissement public foncier d'Île-de-France (EPFIF) and the Institut Paris Region (IPR). The aim of the observatory is to report on the urban and social transformations linked to the arrival of the metro, at the level of station districts, lines and the network.
Ten years after the first survey, a new phase of the observatory has begun. In keeping with the timetable for the start of operations, the new studies are based on the same perimeter around each station, with an 800-meter radius corresponding to the immediate area of influence covered in a 10-15 minute walk. They also include the main indicators for comparative analysis.
Seven themes provide a fine-grained overview of current and future urban changes - Living environment - Population and jobs - Housing supply and prices - Local life, uses and new centrality - Accessibility and mobility - Environment. They are accompanied by a simple datavisualization, accessible to all from the Apur website and updated every year.
