Achieved impacts

The surface water system in the VINEX location Leidsche Rijn near Utrecht is a special water system. Nowhere in the Netherlands is the surface water of such a large urban area treated in such a sustainable and climate-proof manner (ref. 2). In Leidsche Rijn, a relatively new city district of Utrecht, a sustainable closed circuit water system was introduced including natural wetlands, bioswales, pumping stations and permeable paving which filters stormwater organically. It is viewed as a more sustainable solution compared to traditional stormwater infrastructure because it benefits biodiversity (e.g. by means of fish passages) and prevents the need for storm water facilities and the influx of unfiltered surface water from elsewhere (ref. 1-3).

The Water of Leith is home to a wide diversity of plants and animals. The river performs an important flood control function in the city. A management plan envisions to create a healthy river that flows through a green corridor from the hills to the sea and is a haven for wildlife, is enjoyed and managed by the public, and is valued for its built and cultural heritage. The current intervention is about an extensive Flood Prevention Scheme. Walls and other flood defence measures have been constructed from Murrayfield downstream to Bonnington. A re-modelling exercise is being carried out to include the impact of climate change on the river system and the efficacy of the flood prevention scheme. The Water of Leith Conservation Trust works to conserve and enhance the river, its heritage and wildlife. It also promotes education and recreation and works with volunteers and community groups (ref 1, 2, 3).

The Morningside Park is classified within the Edinburgh Public Parks and Gardens Strategy as a “Community Park”. This is a small, pleasant, elongated park area with tennis court, multi-sport area, grass areas and tarred pathways that make the Park an attractive facility for children, young people, adults and senior citizens. The park provides an essential green space in the heart of Morningside with a design which lends itself to a range of activities. The layout of the park provides healthy and safe routes between linked road networks along tree-lined paths. (ref. 1)

The Fechenheimer Mainbogen is the largest undeveloped floodplain area in Frankfurt am Main and a special recreational area in the Frankfurt Green Belt Internal link. Today, the Main Arch is mainly used for agriculture, but still contains numerous relics of a typical floodplain landscape, such as smaller floodplain trees, meadows and wet bank areas. Since 2015, the curve of the Main has been transformed back into a near-natural meadow landscape with water, alluvial forests and meadows in several steps. Animals and plants are given new valuable habitats and places of retreat, and people are given attractive recreational spaces in nature (10).

Platenstrasse in the Ginnheim district of Frankfurt was laid out as a four-lane feeder in the 1960s. It leads through the settlement of the same name, which was formerly the housing area of ​​the US armed forces. After their withdrawal in 1994, the settlement came into municipal ownership. Many large families, often with a migration background, moved in. Wild parking lots and storage spaces were created without any quality of stay. In 2000, discussion about the redesign of the Plattenstrasse started and in 2015 it was completely transformed into a green corridor. The street space was rearranged and the paved areas were reduced to the necessary extent. Sensitive planning and respect for the established structures helped to preserve the character of the district while significantly increasing the green area with recreational facilities. (1)

"This disctrict of "Plateau de Haye" is part of the EcoQuartier approach, is one of the most ambitious urban renewal projects. In line with the development of the New Urban Renewal Program, work was carried out this year [2012] on the challenges of opening up territory to its urban and forestry environment in order to confirm the "Forest City" approach initiated by the architect-town planner Alexandre Chemetoff" (Ref. 1). It received the EcoQuartier National Grand Prize (Ref. 2). A forest, community gardens and a green corridor are being developed with a rainwater recovery system (Ref. 2). Work is set to continue until 2024 (Ref. 10). "It will first allow work to be done on the functionalities of the district : development of spaces freed up by the demolition of the Blanc Sycamore and the Purple Beech, reconversion of the Tamaris and Ombelles into housing, shops and spaces dedicated to companies, creation of green spaces , shared gardens and parking" (Ref. 10).

The South Pennine Moors is a conservation area in the Natura 2000 network. This site is crucial for active blanket bog and is part of two Special Protection Areas in the Birds Directive, including golden plover, dunlin, short-eared owl and merlin, dependent on the blanket bog for breeding and feeding. The conservation status of the site is threatened due to sulphate and nitrate pollution, causing severe depletion of crucial sphagnum moss cover. Fire damage has led to more extreme erosion than if the moorlands had remained sphagnum-rich. The restoration of favourable conditions thereby depends on re-establishing a sphagnum-rich bog. (3)
The project included three Natura 2000 sites, the Peak District Moors (South Pennine Moors Phase 1), South Pennine Moors Phase 2 and South Pennine Moors (3).

Park Sainte-Marie is the second largest park in Nancy (Ref. 8). "The park Sainte-Marie hides varieties of splendid oaks and many other rare plants. It also hosts that annual "Nature in Festivities" event in the first weekend of May which represents the largest plant market in the region (Ref. 2). "This park was awarded the "Tourism and Handicap" labels in 2007 and "Outstanding Garden" in 2010" (Ref. 1). "An old Alsatian House , created for the International Exhibition of the East of France in 1909" is conserved within the park (Ref. 8).

The district will initially incorporate 516 new low carbon homes alongside manufacturing, leisure, offices and climate-resilient public realm. (2) The overall approach to landscaping, amenity space and public realm in the scheme is to make use of sustainable drainage techniques, enhance the biodiversity value of the River Aire corridor, provide an appropriate level of landscaped publicly accessible open space, and contribute positively to the overall distinctive sense of place at the site.

"The desire to integrate trees in the heart of Nancy constitutes a long-standing commitment. The first Charter for Trees of Nancy was signed in 1996. Plant diversity was strengthened and the protection of trees accentuated, in particular thanks to the requirements of the Local Urban Planning. In 2013, the new version of the Charter will make it possible to engage all the actors of urban policy to increase protection of the tree, to be vital to biodiversity and to the quality of the living environment" (Ref. 1). "New legal, urban, ecological and social issues have emerged. The old charter now requires improvements in the face of certain evolutions. It was decided to renew it. This new document is in line with the previous one and faces the new issues of the trees in the city" (Ref. 1, p 9).
