The Interpretation Centre at the Cardiff Castle is displaying a green roof of wildflowers. As well as changing the look of the roof, the wildflower meadow has increased the biodiversity of the area. The nectar-rich species of wildflower turf attract bees, butterflies and other pollinators. The roof had a simple irrigation system built into the substrate where the maintenance would be minimal (ref 3).

The project aims to preserve the river ecosystem and provide a suitable place for social life by the river. For the purpose, only natural materials will be used in strengthening the basin. Part of the activities include planting grass and natural vegetation in order to boost the ecosystem, including tall plants that provide shelter and a nesting place for birds. The area under work will cover 10.6 kilometres of the urban part of the river (Ref. 1).

In response to floods that had been afflicting the Rhiwbina area of Cardiff, a capital scheme was promoted in order to develop an integrated Rhiwbina Flood Defence Scheme. First, a pond was built in the Caedlyn Park to capture peak flows during extreme rainfall (ref 2; ref 8). The City of Cardiff also built low walls alongside the brook that flows through the neighbourhood to better channel water while also removing debris and reinstating the banks that had eroded over time (ref 1; ref 2). Additionally, by realigning and widening the watercourse, establishing earth bunds and creating a large attenuation pond downstream that aligns with the drainage system (ref 7). Taken together, flood risk decreased for the area overall, assisting local residents.

The project involves the BBC Drama Village - a combination of studios and stores with associated offices and technical suites. It was the requirement for all buildings to achieve a BREEAM Excellent standard (ref 1). GreenBlue Urban structural RootCell systems were used for this development to create adequate tree root volumes, to ensure optimum tree establishment and growth in a demanding coastal location (ref 2). A Living Wall has been made which has a number of functions including the provision of a new home for solitary bees, lacewings and other invertebrates. A rainwater harvesting system has been installed (ref 1). Speaking generally, the studio, stores and office amounted to over 18,000 square meters and 900 new meters of HV, gas water drainage and telecoms (ref 1). Areas of eco-design include transportation, energy efficiency, water efficiency, materials, indoor environmental quality, waste reduction and biodiversity (ref 1).

"The proposal is to create a leisure landscape in the countryside to the south of Wakefield, Featherstone and the South East Rural Renaissance areas. The project looks at integrating a series of existing environmental and historic attractions such as Nostell Priory Estate, Newmillerdam Country Park, Haw Park and Anglers Country Park in a landscape that is shaped by reclaimed open cast mining, and features e.g. an innovative forest planting scheme". The proposal is part of the ‘Strategic projects’ to deliver Wakefield’s vision for green infrastructure. (Ref. 1, 2)

In the new district ‘Kop Zuidas’, water green strip is created along the sidewalk in which stormwater is temporarily stored by means of high-grade vegetation and a drainage system. The stormwater slowly infiltrates into the soil and only reaches the sewage system in case of extremely heavy rainfall. It is a pilot project for stormwater retention and will be upscaled throughout Amsterdam when successful. (1,2)

Belfast is located within the River Lagan Catchment and is at risk from flash floods caused by storm water unable to drain away into the combined storm and sewerage network. The Local Development Plan will facilitate the development of green infrastructure resource or ecosystem services such as the green wedges in Lagan Valley Regional Park (ref 2). Lagan Canal is one of the emerging partnership projects to produce plans to restore and revitalise the Lagan Canal corridor. The river Lagan and the canal is an asset for the city, and for the wider region (Ref 1).

As an open root space, climbing plants usually only need a small floor area. Such planting areas can be cut out in a semicircular shape
directly on the facade, for example in the eaves strip of the roof overhangs (irrigation may be necessary). The city department for urban development initiated a funding programme for green facades and walls on private property in the city district of Wolbeck. It formed part of the proposed measures of the urban redevelopment programme for the district to improve its attractiveness and enhance green spaces. It included the reimbursement of up to 70 per cent of the arising material costs provided that the owner commits to maintaining the green façade for ten years. Although only three parties participated in the programme, public awareness of the multiple benefits of green space were raised (ref. 1, 2, 3 and 4).

In 2015, 20,000 British Pounds have been raised to help wildlife in the Elba Park in Sunderland. The funding was granted to create new habitat for priority species in Shiney Row in Elba park. Community groups and schools were one of the major parts of the project. People were engaged to enhance their learning experience. This project was partly crowd-funded (Ref 1).

"Walking pathway located on the banks of the river of the Arc which flows to the south of the city. It follows the meanders of the river and includes games for children, a fitness trail, meadows in the shade of tall trees that border the stream. It covers an area of 10 hectares." (Ref. 1)
