RIVER PARK OF THE QUARRY LOOP
Quarries near Poissy / 2009-2024 / Construction underway
Nelson Mandela Park is located in the southern part of the Seine River loop. It is part of a broader development plan for the Seine riverbanks, the Seine Aval National Interest Operation (OIN). The Chanteloup loop, in which it is situated, is an important component of this OIN and a gateway to Seine Park. The Seine Park program aims to reconnect the Seine with its residents.
A true ecological corridor, Nelson Mandela Park (10 hectares) will serve as a unifying element between the new neighborhoods and the historic city, linking them to the Seine via the Parc du Peuple de l'Herbe. This urban park will offer pathways between the east and west districts, enlivened by the development of platforms with different themes (play, relaxation, picnics, etc.), fostering a strong and diverse social dynamic.
The strength of the proposal from the Ilex and Sempervirens group, landscape architects Safège and Biotope, lies in the design of an urban park which offers stitching functions between the East/West districts where each crossing is enlivened by the development of platforms with different themes allowing to create a strong and diverse social dynamic.
In the North/South direction, the park presents itself as a "Rotule" piece connecting the different biotopes that make up the Seine, the Sensitive Natural Area (Parc du Peuple de l'Herbe) to the south, the agricultural plain and the surface compensation zone to the north.
Based on the guidelines outlined in the specifications, the team was able to propose a balanced design, leveraging the park's programmatic constraints to create strengths and thus meet social and environmental objectives by reconciling urban and natural environments. Their guiding principle: "the meander park is designed in conjunction with the city and its surrounding environments."
A form of "urban nature"
Currently located on the site of former quarries and soon to be at the heart of the new Carrières Centralité constructions, the urban park will constitute "a true continuum of urban nature" linking both the historic city to the St Louis district (east-west) and the agricultural plain of the Chanteloup loop to the future departmental park of the People of the Grass (north-south).
This project is thus designed to complement the urban project by linking environments, from the most natural to the most urban, and to constitute a mosaic of atmospheres and places, with the primary quality of being alive and evolving.
The earthworks for the green corridor will allow the collection of rainwater and runoff from part of the ZAC, and provide an alternative and sustainable water management system.
The concept of island platforms
In addition to its central location, the park will be a true natural place for living and interaction.
Featuring numerous "island platforms", it will offer multiple routes where "surprises" will be revealed: a picnic area, games, sports or rest areas, educational gardens, etc.
This game of "floating places" will take the unique form of square platforms of varying sizes distributed throughout the narrow, urban part of the park.
The urban park, a place for exchange and consultation
The definition of this project will be the result of a series of workshops bringing together associations and local residents, the services of the city of Carrières-sous-Poissy, the selected operators, the architect of the development zone, and EPAMSA. The facilities and the overall design will thus be chosen and adapted as closely as possible to local needs.
The work includes:
The construction of platform structures and coverings
Supply and installation of playground and fitness area equipment;
Supply and installation of furniture;
The manufacture and installation of locks
Ecological innovationand water management
The 18 months of work for the first phase of the parkNelson Mandela will enable the implementationof three retention basins which will contribute toflood management of the Seine and recoveryrainwater.
Innovation also lies in soil treatment,studied in detail by the project engineers. On theseformer quarries, the challenge lies in dealing with thepollution and create fertile soil, where crops willThey ensure the longevity of the structure while minimizing excavation. The base of theThe park will therefore be redesigned, prioritizing the usehealthy soil from the site and adding someTopsoil (6m3)per tree and a thickness of30 cm for meadows).
This urban park is intended to be the link that will unifyCarrières-sous-Poissy, an essential link between theThe Seine and the former agricultural plain. The first stageof the development of Nelson Mandela Park consists ofdraw the two paths that will cross the park of
north to south and encircle the seven spaces and their pathscrossroads where residents can relax (picnic area and solarium), play sports (fitness center and multi-sports court) orplaying with their children (naturalist goose game, drops)water and nets).
Ultimately, it will offer a vast natural space inin the heart of the city with the planting of 279 new trees and1664 saplings (October 2022), grassed areas,groves and clearings promoting biodiversity.
Ecological floodable park, ecological corridor from the Seine to the plateau (forest of Hautil), stormwater management, improvement of the quality of the waters of the Seine (depollution, oxygenation, creation of spawning areas), alternative management of stormwater in public space (ecological fountain and water feature).
Shared gardens, urban furniture and innovative games, sports fields, sports trails...), reasoned and agricultural management of large spaces (Harvesting, creation of biomass).
