Interventions on the trees to prepare the development of the new line

As part of the Tzen 5 work, several interventions on trees will be carried out between the beginning of November 2026 and March 2027 in the municipality of Vitry-sur-Seine. In total, five trees are concerned as part of the upcoming operation. These interventions are necessary for the realization of the future development of the project. They will make it possible to improve the performance of public transport while developing pleasant and safe paths for active mobility, particularly for bicycles.

In the Fusillés sector in Vitry-sur-Seine, three trees must be removed to allow the insertion of the Île-de-France Bicycle Network (VIF). This operation will improve cycling continuities throughout the region and will eventually offer a safe cycle path to Paris in the north and to Melun and Saint-Fargeau-Ponthierry in the south. This work will make it possible to better integrate bicycle travel alongside the Tzen 5. In addition, four new trees will be planted in this sector, at the level of the future station.

Two other trees are also concerned in Vitry-sur-Seine, in the area of the Leclerc shopping centre. Their removal will allow the redevelopment of the intersection between Quai Jules-Guesde and Rue Eugène-Hénaff. Its new configuration will better integrate the different uses of public space with the arrival of the future Tzen 5 bus, the maintenance of car traffic and the development of safe pedestrian and cycle paths. This redevelopment will eventually be accompanied by significant revegetation of the sector, which is currently characterised by highly mineral areas, with the planting of 36 new trees to combat heat islands.

In Ivry-sur-Seine, a tree located near the intersection between Rue Bruneseau and Quai Marcel-Boyer, at the level of the future Marcel Boyer / Bruneseau station, is also concerned by an intervention that will be carried out later in 2027.

These one-off interventions are part of a more global project to revegetate and share the public space near Tzen 5. The studies carried out during the design of the project sought the most favourable solutions for the preservation of existing trees. When the conservation of certain trees was not possible, the interventions were limited to what was strictly necessary to allow the development to be carried out. On the scale of the entire route, 285 trees will be planted for 128 trees felled, i.e. more than two trees planted for each tree removed. 51 existing trees have been preserved.

In the Executed zone:

• 3 fellings to continue the development of the Vélo Île-de-France (VIF) network
• 4 trees replanted in the immediate vicinity of the future resort

In the commercial area:

• 2 felling operations to redevelop the intersection and create the dedicated site
• 36 trees to be replanted in the long term in a very mineral environment with few trees

The overall assessment

• On the scale of the route, the balance sheet amounts to 128 trees felled for 285 trees planted, i.e. 2.22 trees planted for 1 tree felled.
• Île-de-France Mobilités' commitment to compensate at least 1 tree for every 1 tree felled and to aim for 3 trees replanted for every 1 tree felled has been kept. In addition, 51 trees on the route have been preserved.

Assessment by municipality

• Paris: no trees felled and no trees planted
• Ivry-sur-Seine: 5 trees felled for 18 trees planted => ratio of 3.6
• Vitry-sur-Seine: 72 felled for 210 planted => ratio of 2.9
• Choisy-le-Roi: 51 trees felled for 57 planted => ratio of 1.12
