Improved stormwater management

This intervention involved the realignment and merging of St. Mary's Way and Livingstone road into "St. Mary's Way Boulevard" of which a sustainable urban drainage (SUD) system is a key component. It consists of 31 large specimen trees that are planted in soil cells. The purpose of this project was to improve pedestrian accessibility, attract net investors, and to enhance the water drainage system (Ref 1).

Renovations were conducted on Bayard Street, an artery in Toulouse, between 2016 and 2017 Rue Bayard, in anticipation of the arrival in 2024 of a new metro station and the complete overhaul of the Matabiau district (Ref. 10). Renovations included introducing vegetation to the commercial street leading to Matabiau station (Ref. 5) and its newly renovated city centre via planting 81 trees (44 pear trees and 37 hazel trees of Byzantium) (Ref. 2). Furniture was also added and sidewalks were widened for greater pedestrian comfort (Ref. 2).

The former site of the Krupp cast steel factory was transformed into a 230 hectares green belt stretching from the city
center to the district of Altendorf, while the adjacent industrial wasteland was turned into an 11 hectares add-on to the Krupp Park (Ref. 1). The landscape vision "Freiraum creates urban space", in which the Krupp Park is a building block, is a comprehensive strategic approach that aims to gradually build up new urban landscape structures and to create diverse qualities of location for different urban uses" (Ref. 9).

The office building of the Nord/LB Bank that was built in 2002 became a landmark of Hannover. A huge proportion of the building is naturally ventilated. The interior is designed with progressive energy concept with superstructure exposed and windows that provide ventilation. The building is also protected from noise and vehicle emissions through the areas of double façade, which also serves as a duct transferring clean air from the central courtyard to the individual offices. The reflection of daylight is increased through the large areas of water in the courtyard which also contributes towards a beneficial microclimate. The building is also equipped with generous roof gardens which not only provides aesthetic benefits but also improves the general climate for the occupants, and collects rainwater for irrigation and use within the building.
The building is owned by Norddeutshce Landesbank and was designed by BEHNISCH, BEHNISCH & PARTNER (Reference 2).

The Urban Environment Observatory Building (OMAU) was built in Malaga as part of the URB-AL 1998 project, it is a construction planned for environmental conservation and includes an ecological cover for the use of rain water in the supply to the structure's watering system. (Ref 2, 3)

The Development of the Garden of the Schloessel project is part of the Natural Urban Park project undertaken by the City Council in consultation with the Strasbourg Urban Community (Ref. 3). The project aims to reduce the carbon footprint of the area by installing and redeveloping green spaces in the garden as well as providing the site with stormwater management infiltration (Ref. 1).

The San Rafael Park is an urban park and commemoration site built over former communal graves containing more than 2000 bodies of victims of the Spanish Civil War and the Franquista regime. The large project has had 4 phases, three of which have been completed, including the building of a Historical Memory Pantheon to commemorate the victims in the communal graves exhumed from the grounds where the park now stands. (ref 1) In these phases are numerous reforestation and water preservation plans (ref 1-7) including the gardening of more than 4,000m² of green area with 104 shade trees, 8 palm trees and more than 400 units of shrubs, in addition to covering the rest of the surface with perennials and meadows (ref 3).

The rehabilitation of the main road Alameda Principal seeks to invert the previous distribution of use of space that saw 70% of it devoted to car usage and 30% to pedestrian use, after the intervention the situation should be 75% civilian and pedestrian space and 25% for cars. (Ref. 4,5) More public spaces, green areas, walks, bike lanes and leisure facilities will characterize this action, which also prioritizes highlighting the identity of this area of the city and value its architectural elements, patrimonial, wooded vault and cultural links. (Ref. 4)

Working with Cardiff local authorities, Dwr Cymru Welsh Water's (DCWW) upgraded Trelawney Avenue to its RainScape Sustainable Drainage System (SuDS) (Ref. 4) which alleviated risk to residents and nearby highway which were at a 2 in 10 year flood risk (highly-risky) (Ref. 3). Flooding commonly occurred due to rainwater run-off from the roofs and roads of upstream catchments that drained into a combined, overburdened sewer network. Traditional systems of increasing pipe-size and storage were not cost effective (Ref. 3). A sustainable solution was developed which combined road surface drainage (gullies and slotted grates) and provided water-butts (200 liter reservoirs for roof drains) to 101 properties in Trelawney Avenue and to 75 properties in the upstream catchment (Ref. 3). Additionally, a wall was built to protect properties from the potential effects from surface water run-off (Ref. 1).

“Balne Lane Fields are an area of land close to the city centre of Wakefield. The site comprises of an area of nine hectares, which includes a former landfill site that has been restored to open green space. Part of the site is within a flood zone (Balne Beck).” “The field is popular with the local population for informal recreation. The potential to improve the variety of recreational uses, ecological value and environmental quality together with its links to both local communities and strategic greenspaces make it an important piece of green infrastructure in the City of Wakefield.” (Ref. 1)
