Urban transformations in station neighbourhoods on Line 15 South

In 2025, Line 15 South of the Grand Paris Express will serve 16 new stations. Over 4.1 million square metres are included in the programme shared between 80 projects that cover 21% of the surface area of station neighbourhoods.

These figures have been analysed and put into perspective in the study “Transformations in Grand Paris Express station neighbourhoods - 35 stations to be in service by 2025”.

Over the next 10 years these projects will create 33,000 housing units, 1.4 million m2 of office space, 0.9 million m2 surface area for other business activities. Urban renovation operations are also underway in 12 neighbourhoods out of the 16 which will ensure that populations already living there will remain and will improve their living environment.

The study emphasises a trend towards re-establishing the balance of a functional and social diversity. Ultimately, the operations underway and to come should bring about an equilibrium of 60% housing, 40% businesses.

Many incentives for reducing inequalities were identified, among which the improved accessibility for social housing complexes, a significant number of diverse types of housing produced with a high proportion of social housing, (30% social housing in station neighbourhoods today and on average 800 new social housing units to be produced each year). Better metropolitan facility services of will thus be supplied, for example : educational establishments, Gustave Roussy, Cité Descartes, etc.).

At the environmental level, although the study shows that projects of the future are more committed and ambitious compared with those already carried out, the multiplicity of key players does not facilitate the acceleration needed to meet the challenges of an inclusive and zero carbon city. Geothermal energy, the use of wood, recycling excavated soil are but a few of the actions often carried out during the implementation of projects. The analyses of the present situation underline that no special place has been given to public space together with the necessity to increase cycling facilities to enable feeder services at stations.

Finally, even if territorial rebalancing is included in programmes, the gap between implementation and the analysis of operation schedules still shows today an enormous contrast between the two extremities of the line. To the west, the Pont de Sèvres neighbourhood is very advanced in its process of transformation with a greatly increased density, whereas to the east, in Noisy-Champs neighbourhood, where objectives are the same, there is a discrepancy in the level of achievement of 10 to 20 years.
This study on urban transformation in station neighbourhoods on Line 15 South is the first of its kind to be published by the Observatory of Station Neighbourhoods managed by Apur, the company Société du Grand Paris and the Regional and Interdepartmental Department for Infrastructures and Development -DRIEA-. A second study will be published during the summer dealing with other stations to be delivered by 2025.
