The Parc Départemental of the Fosse-Maussoin at Clichy-sous-Bois (93, Seine-Saint-Denis) is open to the public, who are able to enjoy this managed wooded area. In a very dense urban region, it extends over 35 acres and represents a very lovely natural space in the city. In January 2021, the département of Seine-Saint-Denis officially opened this first extension of the park.
Other development work is under way to provide 55 acres of « green lung » including a biodiversity zone. To this end, 17 additional acres are being developed. This new space will offer a panoramic view over Seine-Saint-Denis and Paris with the completion of a landscaped lookout point. New leisure facilities complement the promenade, including a games zone and a picnic area. Access will be enhanced, with two new entry points to the Park. Finally, 2,000 trees have just been planted.
ECT created the landforms and facilities for this eighth regional park for the Seine-Saint-Denis département by providing inert soil from local construction sites.
