Le Jardin de Niel
Short description of the intervention
The garden was designed by landscapers Michèle Orliac and Miquel Battle and realized for a cost of 3 million euros. This "new green lung", as presented by the City Hall of Toulouse, is part of a major urban project that provides for the creation of 500 housing units in the Niel District (Ref. 1). The project involved creating vegetation enmeshed benches (Ref. 7) and using permeable flooring materials that prevent water loss and reduce the potential of flooding (Ref. 8).

Implementation activities
The “jardin Niel” public garden is the parade ground of the former "Caserne Niel" military barracks (Ref. 2). The architects behind the development of the garden Michèle & Miquel were selected in 2006 (Ref. 5). Its development program was conceived following, in particular, a consultation workshop organized in 2010 as part of the Empalot urban renewal project. Subsequently, the project was regularly informed by local democracy (Ref. 3). The green space was delivered and open for public use in December 2013 (Ref. 6). The benches were created in wire mesh so that the vegetation could grow through uninhibited (Ref. 7). The use of Flexbrick (open or wide-seamed ceramic tiles) in the park meanwhile offers technical advantages by favouring soil drainage, preventing drainage water loss and reducing the impact of floods caused by heavy rain (Ref. 8). The space is also equipped with rest areas, picnic areas, and playgrounds (Ref. 3). "Designed as a series of hills where walkers can find children's games , balloons and slides. It will be reserved for pedestrians and bicycles since all entrances for cars have been removed" (Ref. 1).

help the most underprivileged districts by taking into account environmental issues (Ref. 9).

(3, 9)
Description of environmental benefits
Environmental quality:
-Improved air quality: "To create a "new green lung", for the City of Toulouse" (Ref. 1).

Water management and blue areas:
-Increased protection against flooding: the use of flexbrick "... favors soil drainage, prevents water loss in drains and reduces the impact of floods produced by abundant rains" (Ref. 8)

Green space and habitat:
-Promote naturalistic styles of landscape design for urban development: "The natural topography of this elevated point that overlooks the Garonne River has always preserved the site form floods and made it a special place since far back in history" (Ref. 2).
-Increased green space area: "The old existing plane trees alignments on both sides of the central topography are refitted. They create both a green and urban filter between the garden and the surrounding buildings. Furthermore, on the hills, random maple trees plantations create a grove atmosphere" (Ref. 2).; recreational space designs - such as wire mesh benches - that allow the growth of vegetation (Ref. 7).
Please specify other socio-cultural impact
cohesion/economic development/ equal opportunities against discrimination: The projects linked to the PUI project are required to respond to European cohesion policy on the promotion of economic development, competitiveness, employment, sustainable development as well as urban and territorial cohesion, by taking into account the environmental protection issue, and the fight for equal opportunities and against discrimination. (3, 9)
Description of economic benefits
Increase of jobs: The Michèle & Miquel architecture and landscaping studio were responsible for the project's landscape architecture (Ref. 4, 5).
Stimulate development in deprived areas: The City of Toulouse defines part of the "Toulouse Integrated Urban Project" as a sustainable urban development project (Aspect 2) to help the most underprivileged districts by taking into account environmental issues (Ref. 9).
Please specify other environmental justice issue
equal opportunities against discrimination: The projects linked to the PUI project are required to respond to European cohesion policy on the promotion of economic development, competitiveness, employment, sustainable development as well as urban and territorial cohesion, by taking into account the environmental protection issue, and the fight for equal opportunities and against discrimination. (3, 9)
Description of social and cultural benefits
Social justice and cohesion:
-Improved access to urban green space: "This garden is one of the main features of the connection between both districts and the banks of the “Garonne” river that crosses the city" (Ref. 2).
-Increased opportunities for social interaction: "A large brick forecourt in front of the « Maison des associations » community center, at the “jardin Niel” garden entrance is a meeting and multiple activity space" (Ref. 2).

Health and wellbeing:
-Gain in activities for recreation and exercise: "designed as a series of hills where walkers can find children's games , balloons and slides. It will be reserved for pedestrians and bicycles since all entrances for cars have been removed" (Ref. 1).

Cultural heritage and sense of place:
-Increased sense of place identity, memory and belonging/Protection of historic and cultural landscape / infrastructure: "The project tries to remind this situation and history. The park covers this precious archaeological site for the next generations; this is why it has been impossible to excavate the entire area. The proposal highlights the topography of the site, considering the presence of archaeological remains that forbid all intervention and plantation at the existing ground level: the garden’s takes the shape of an undulating shroud that covers the buried treasures" (Ref. 2).

cohesion/economic development/ equal opportunities against discrimination/increased visibility: The projects linked to the PUI project are required to respond to European cohesion policy on the promotion of economic development, competitiveness, employment, sustainable development as well as urban and territorial cohesion, by taking into account the environmental protection issue, and the fight for equal opportunities and against discrimination.
