The EcoQuartier Luciline Rives de Seine (Luciline) is part of a broader process of reconquesting the western districts of Rouen and in the development of the Seine axis within a global Rouen Seine Cité project, which includes two other major projects along the Seine: the EcoQuartier Flaubert (EQF) and the New Gare district. These projects address the housing needs of the inhabitants and the challenges of developing innovative activities, services and higher services. It concentrates in a single set a mix of functions. Part of the 2014-2020 Agglomeration contract signed with the Region in the framework of axis 3 entitled "Building the city of tomorrow, the operation also benefits from subsidies awarded by the State through the "EcoCité" scheme. Like all the other operations mentioned, the Luciline — Seine River project is involved in the process of reconquesting the banks of the Seine. The community’s stated desire is to reconcile the city with its river and to restore to the Seine its fundamental role in the landscape, ecosystem and functioning of the Metropolis. The project is also part of the desire to fight against urban sprawl that prioritises the renewal of the city on its own and a reasoned densification of the urban fabric.This is why the development of EcoQuartier Luciline, on the north bank of the Seine, is a dense and mixed urban project. The construction programme on this operation provides for 1,000 new dwellings, 25 % of which are social rental housing and 25 % of dwellings with controlled costs, and about 60.000 m of shops and activities including the permanent motor vehicle trading. Built shapes vary from townhouse to building R+ 10. Since its genesis, the project has been the subject of a thorough environmental approach. Particular attention is also paid to consultation and, beyond regulatory obligations, to communication to the public (e.g. during the construction site), as well as the involvement of car dealers, already present on the site and constituting a "specialised commercial centre for the city. Thanks to the method of work and the desire to build a pioneer district in responding to new urban environmental challenges, it soon became clear that water would play a key role. A network of nodes allows the recovery of rainwater from buildings and public spaces, but also to collect those of the Luciline River, now channelled under the site and the exhaur waters of geothermal energy. Water is also an energy resource thanks to the geothermal water system in the neighbourhood. This blue and green frame is the place of pleasure and walk in the neighbourhood and contributes to the preservation of urban biodiversity. This development project is the subject of a ZAC, which was created concurrently with the approval of the Urbanisation Plan of the city of Rouen on 24 September 2004 and whose implementation dossier was approved by deliberation of the Municipal Council of the City of Rouen on 20 May 2005. By way of a concession agreement, the SPL Rouen Normandie Aménagement was subsequently appointed as the master of this development project on behalf of the city of Rouen.
