Improved stormwater management

Győr and its surroundings boast many rivers, streams and lakes, and experiences intense flooding almost every year. The main goal of Nagy-Pándzsa project was to reduce the risk of flood and to regenerate the Nature 2000 area (Reference 7). Due to the reconstruction of the water transporting feature and the reconstruction of the flood-gate, the flood protection could improve and the pollution of waters could decrease. Therefore, the conditions of flora and fauna of waters improved and the size of the utilizable area increased (Reference 8).

Situated in park Spilberk, the garden features a building with a green roof and a garden with various plots. The building is designed to be carbon neutral and reuses rainwater for toilet flushing and for watering the garden plots. The garden is used for horticultural purposes and environmental education, as well as animal and beekeeping. The complex improves the local micro-climate through cooling and humidification and promotes biodiversity. (Ref. 1; Ref. 2; Ref. 5; Ref. 6)

This project worked to revitalize the area along the river Old Ponávka. This involves the creation of walking paths, bike paths, and public playgrounds. (Ref. 1). Stará Ponávka and the adjoining Svitavy drive were built in the 13th century in the original riverbeds of Ponávka and Svitava before their regulation. By revitalizing this watercourse, the city returned water back to the city, made it accessible to people and improved the natural state of the site (Ref. 14).

The Royal Palace of Naples (Palazzo Reale di Napoli) is a palace, museum, and historical tourist destination located in central Naples, southern Italy. In 2016, the rooftop gardens of the Palace were part of the project to renew the historical royal palace to reopen the green space on the top of the Palazzo. The external walls of the internal part have been covered by flowers and plants. In addition, new services have been provided, such as bar, restaurants, recreation areas, providing at the same time economic opportunities and new jobs. (Ref.1.)

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).

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)

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).

This intervention aimed to address low water levels and low water quality in the Sandall Beat Wood and Cantley Park. The problems have been identified by the council and this project was planned to improve the water levels as well as the water quality. This also helped in improving the gross water flow of the regions and protected the wetland habitats. In addition to the above-mentioned benefits, the project successfully engaged local communities. (Ref 2).

A part refurbishment of a classic 1930’s building, the design of the Leeds Greenhouse embraces the history of the building. Along with rooftop wind turbines, solar panels, ground source heating, there are NBS advantages to the property, including central rain and greywater management facilities that support everyday living and working. It also installs nearby allotments as well as on-site shared gardens to help strengthen both the sense of community and sustainable consumption. (1, 2, 3, 6) The building comprises 172 flats and 15,000 sq ft of office space. (7) Even though the project was completed in 2010, the residents came together in 2018 to add 250 hedge-plants to the complex. (13)
