Project scope
Plan: The ZAC perimeter is about 20 hectares, with narrower operational works areas. Planned works include reconfiguring rue Baron-Le-Roy within the ZAC and extending it beneath the Paris périphérique, relocating the Bercy 2 shopping centre, constructing a 200 m tower and a new Valmy bridge over the SNCF maintenance site, and building a deck over part of the railway tracks. Parts of the SNCF railway property, the Richelieu co-ownership and gardens, and the Bercy quays are identified as areas without works. The Paris-side continuation of rue Baron-Le-Roy is part of a separate project; the characteristics of the Seine connection remain unspecified.
Reported status and procurement
- Reported development
Grand Paris Aménagement is described as carrying the ZAC with the State, Charenton-le-Pont municipality and the Paris Est Marne et Bois territorial public establishment.
- Procurement availability
- Unknown / not established
Reported regulatory context
The ZAC was created by prefectural order on 23 September 2022. The order adapting the Val-de-Marne flood-risk plan and bringing the local plan into compatibility was signed on 7 December 2023; the environmental authorization was signed on 1 July 2024; and the declaration of public utility was signed on 22 February 2025. The dossier considered in April 2025 was presented for modification of the ZAC creation order and approval of its realization dossier. The opinion reports legal challenges that create a risk for the ZAC procedure. The environmental-authority opinion itself is advisory, not favorable or unfavorable.
A source report alone does not establish current progress or an open buying window.
Project summary
The environmental-authority opinion dated 10 April 2025 describes the planned ZAC Charenton-Bercy redevelopment in Charenton-le-Pont, near the Seine–Marne confluence. It reports a revised programme of approximately 408,000 m² and planned works including housing, offices and activities, retail and hotel space, public facilities, a 200 m tower, a new Valmy bridge and a deck over part of the railway tracks. At the opinion date, phase 1 was defined for 2025–2030, but control of the Martiniquaise land and authorization for the railway deck remained outstanding conditions. The opinion is advisory, not an authorization decision.
Evidence limits and unknowns
The opinion dated 10 April 2025 does not establish project progress after that date.
The detailed design of the Seine connection was still unspecified; the opinion says it was not expected to be defined more precisely before phase 3.
Phases 2 and 3 were indicative and could change order; their development depended in part on decisions about the AP-HP buildings and Bercy 2.
The authority said no response had been provided to its recommendation for a programme of health-risk measures, detailed and quantified for each phase, with occupancy phased consistently with implementation.
The authority recommended testing the flood studies and resilience strategy against the +4°C climate-adaptation trajectory through 2100.
The opinion reports unresolved soil matters: the AP-HP site-specific diagnostic did not establish compatibility with the project, no new diagnostic was available for the Martiniquaise site, and further assessment was identified for the shopping-centre site before phase 3.
