Water management (SDG 6)

The landscaping of the Vuosaari landfill site has appeared to be an excellent example of ”Integrated Planning Approach” as following concepts were applied: restorative design; ecological design; regenerative development and conventional design (ref. 1). The unused Vuosaari landfill hill had been transformed into a natural area where now domestic plants grow in meadows and rocky conditions. The area is now also used for recreational, educational and scientific purposes (ref 1, 2). The purpose of the project was to promote social, economic and environmental activities at the Vuosaari landfill site (ref. 1).

Kuninkaantammi is a new energy- and eco-efficient residential district by the Vantaa River and Helsinki’s Central Park that is in the construction phase with a dense urban design, consistent with the ecological, experiential and community requirements of modern housing. It will become a climate-smart neighbourhood for 5,000 inhabitants. Environmental factors have already been noted in the zoning of the area, and energy efficiency guides the design and building processes.
Kuninkaantammi will be a pilot project for stormwater runoff management in Helsinki using green infrastructure. The construction is ongoing (2013-2025). Management of storm waters in the area will be carried out through natural methods (ref. 1, 11).

The city of Wuppertal participates as a model region in the joint research project SAMUWA which aims at developing planning instruments which combine urban drainage with urban and open space development measures. With regards to the work package C.1: open space design strategies for a water sensitive city, one focus area and proposed measure, namely the "Varresbecker" flood channel is of special interest since it has been subject to comprehensive implementation plans in Wuppertal so that its implementation can be expected in the next years (Ref. 1, 2, 4 and 5). Alongside the water channel, a recreational area will be created with information to raise awareness about water management issues and climate change. (Ref. 2)

The Podlasie Opera and Philharmonic – European Art Centre in Białystok ("green opera") in Białystok, is known for its green roofs, green walls and extensive gardens, which perfectly harmonize with the surroundings. The green area serves as a platform for cultural events and successfully promotes the city. Opera gardens are divided into several levels with lawns, walking paths, bridges, sculptures, and small ponds. Different green elements of the building reduce heat effect and noise, increase the thermal insulation of the building, improve local biodiversity and limit rain drainage to the city centre [1].

The company running the Zabalgarbi waste disposal site manages a solid waste–to-energy plant and also houses a mechanical biological treatment (MBT) plant, a composting plant, a landfill and a leachate treatment plant. During construction of the first plant, Zabalgarbi regenerated and recovered the entire Artigas-Arraiz area covering 108 hectares. The area was degraded by shaft mining activity and an opencast quarry. The project aimed at the reforestation and landslide mitigation of this degraded area. Today the area has been reforested, trails were built and space provided for people to enjoy themselves in gardens, picnic areas and along forest tracks. (Ref 1)

Zorrotzaurre is an artificial peninsula located within the Deusto district of Bilbao, Spain. It was formed during the 1950s and the 1960s, when a canal was built to facilitate navigation in the estuary of Bilbao. The Zorrotzaurre project is the latest major urban renewal project to commence in Bilbao. It is an integral and sustainable plan that recuperates a currently derelict site to convert it into a new quarter, and which also includes a flood protection system with water tanks to retain water and a flood protection barrier (Ref 1)

The Urban Forest project represents an increase of urban trees in the city. There will be two phases of this project. In the first, it consists of a transformation of an eye-sore and abandoned space, around previous Canodrome, into a large urban forest (Ref 1, 9). The second one will be located in the land of the velodrome of Es Tirador. This projec has been delaid due to unforeseen costs (Ref 10).

GIFT-T (Green Infrastructure For Tomorrow - Together!) is a four-year European project of which Medway was one of five case studies. In this project communities, businesses and governments were brought together to facilitate bottom up planning and implementation of green infrastructure (Ref 1). The product of this is a general business plan, and the planned intervention of focus here is the "Thames Terrace Invertebrates - corridors for wildlife" (Ref 2). Hoo Island already has areas that serve well to sustain invertebra species, but as of yet also has underutilised potential in this respect. This intervention addresses the latter.

Following an extreme flood event on August 9th 2008 in Glendhu Park, eight houses experienced flooding and many more came within inches of being flooded. Two swales were constructed by Dublin City Council to provide surface water storage to ensure that no flooding will recur in a similar 100-year pluvial event. The swales are designed to self-drain back into the existing surface water sewer system following a severe storm event (Ref. 1).

Lodge Hill is a nature area allocated to become a settlement capable of delivering approximately 5000 dwellings by 2028 (original plans). Green infrastructure is a key component of the current plans and specific GI implementation will be based on the existing GI assets. Specifically, the plans include green corridors, sustainable urban drainage systems (SUDs), various parks and street greenery, community allotments, buffer zones around sites of special scientific importance (SSSIs) and woodland (Ref 1).
The plans for Lodge Hill have been controversial, as Chattenden Woods and Lodge Hill Site of Special Scientific Interest (SSSI) is a nationally important area of ancient woodland and rare grassland that supports one of the largest populations of nightingales in the UK (Ref. 7, 8, 9).
In 2018 Kent Wildlife Trust started a campaign (#SaveLodgeHill) to ask Medway Council to not to allocate Lodge Hill development, which has resulted in a scaled-back version of the original plans for Lodge Hill from the construction of 2,000 to 500 houses, avoiding any direct loss of the Site of Special Scientific Interest - which will still have an impact on the nightingale's population (Reg. 7).
