Good Practice Information

In 2010, the SAN of Marne-la-Vallée – Val Maubuée started a process of management of the Marne’s riverbanks. The aim was to create a pedestrian continuity along the Marne for the users’ well-being and planted areas with the objective to permit to the park users’ to rediscover the river. The phase 1 of the project was for the Val-Maubuée to set up a landscaping strategy with a strong ecological and biodiversity-friendly characteristic.
The main objectives of the landscaping strategy were: extend the promenade on the riverbanks, preserve the natural character of the site, offer varied environmental atmospheres, build new infrastructures and remedy the watersides erosion.
The SAN Val Maubuée wanted to evaluate the environmental impacts of these works and draw up a carbon footprint to preserve environment and reduce the impact of constructions. The suppliers have been chosen close to the site and innovative measures have been taken to respect the SAN Val Maubuée’s priorities.
The main actors were: the SAN Val Maubuée Green Spaces Department as project manager, the municipality of Torcy as a partner, the Department Council of the 77 and the Region Ile de France for co-funding, experts from ecological firms on landscape management, hydraulics, geotechnical, etc, the ADEME (French Environment and Energy Management Agency) to set up the carbon footprint method, appraisal services from the prefecture, the SAN, etc., and finally the park users’.

The phase 1 of the project, the environmental monitoring was funded by:
- The Region Ile de France: 40%
- The Department Council: 40%
- The SAN Val-Maubuée: 20%

The total cost for the phase 1 was: 257 000€ including tax + various studies (geotechnical, etc) 61 000€ including tax.

The implementation costs of the public works were of 2 370 000€ including tax.

Evidence of success

This practice is considered as a success for several reasons:
• Its innovative aspect: access to the work site by waterway to reduce the number of trucks on the roads, re-use of green waste from slaughter, strengthening of banks by bioengineering techniques, protection of trees and creation of new habitats for wildlife and the choice of suppliers which were close to the site.
• The environmental criteria have been included in the landscaping strategy.
• There has been a significant reduction of environmental impacts of the project and achievable and measurable objectives during the conception and implementation of works: 220 trucks have been avoided on roads thanks to the use of river roads, savings of 5% of greenhouse gaz emissions have been made and the growth of planted trees will permit a reduction of 30% in total emissions.
