A densely populated, mixed-use neighborhood with 23,870 residents and 11,160 salaried jobs, the Arcueil train station neighborhood is also a hub for higher education thanks to the presence of the ESTP engineering school and the Cachan campus to the south. – Cachan district is also notable for its proximity to the town centers of Arcueil and Cachan and the Vanne aqueduct, a spectacular landmark. Twenty-nine percent of the housing is social housing, making it the third most socially mixed district of the Grand Paris Express. The private gardens of the detached houses and large housing estates contribute to the presence of vegetation, and a hectare of new green spaces open to the public is planned. The population increase is largely due to the delivery of numerous new developments, particularly in the Camille Desmoulins ZAC (joint development zone), but also to multiple scattered developments, including the Cousté-Dolet sector in Cachan and along the RD920 in Bagneux. The transformation of the neighborhood will continue through six ongoing development projects covering 74 hectares, including 22 hectares strictly within the station neighborhood perimeter.
Launched in 2013, the Grand Paris Express station neighborhood observatory is a partnership tool that brings together the Paris Urban Planning Agency (Apur), the Société des grands projets (SGP), the Regional and Interdepartmental Directorate for the Environment, Development and Transport (DRIEAT) and the National Institute of Statistics and Economic Studies (INSEE), as well as the Établissement public foncier d'Île-de-France (EPFIF) and the Institut Paris Region (IPR). Its aim 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.
