Achieved impacts

The project assumes planting roses and other flowery shrubs in the Szczecin's district of Kijewo. Characterized by heavy traffic, the area has benefited from 'rose gardens' along its main roads and neighbourhood squares as a way of mitigating the traffic noise. The rose gardens serve as natural acoustic screens for noise reduction. The initiative additionally aims to enhance the aesthetics of the area and the image of the Szczecin's city - in line with its long-term brand management strategy "Szczecin floating garden 2050". According to the initiators of the project, it refers to the tradition of roses, which would decorate the same neighbourhood in the past [1].

Due to the challenges caused by climate change, Hamburg decided to become greener and developed a comprehensive, pioneering green roof strategy. The strategy aims at creating 100 hectares of new green walls by 2019 by providing grants for building owners for greening roofs and offering them rain water fee reduction owing to the rain water retention of the green roofs. (Reference 1) The financial support offered until the end of 2019 is 3 million EUR. (Reference 2) The services offered by the city in this plan consist of four pillars: promotion (financial incentive), dialogue, regulation, and scientific support. (Reference 7)

Since the mid-eighties, several German cities like Karlsruhe have been implementing green tram tracks, followed by a period of decline due to incompatibility with technical and construction requirements (Ref. 2). Since around 2003, the city of Karlsruhe has re-introduced the greening of tram tracks with the main objectives of noise reduction and cloudburst infiltration (climate adaptation). Mostly in combination with urban redevelopment projects, several tram tracks across Karlsruhe have been renewed and greened in different forms by using continuously advancing technologies (Ref. 3, 6 and 7).

With the relocation of the railways between the Hauptbahnhof and Pasing a large area became available for an infill development strategy. The redevelopment of central railway areas of Munich is in line with the city's guidelines for sustainable development (Perspective München) referred to as compact - urban - green. The initiative is aimed at implementing 7500 new flats and creating 15000 new workplaces in total, which are supported by green recreational areas. (Reference 1) The project consists of six separately planned parts, some are already partially finished. (Reference 2) This NBS discusses Birketweg, one of these parts, which is 60 hectares large.

Manchester’s Stevenson Square was given a green makeover. In addition to securing funds from Manchester City Council, the project underwent a substantial crowd fundraising campaign to transform the square into an ‘urban oasis’ and provide street trees, permeable pavements and planters.The pavement was extended on one side of Stevenson Square which enabled street trees to be planted. More tree planting undertook on the central reservation and a green roof was designed to collect and store rainwater. Self-irrigating hanging baskets were installed on lamp posts (ref 4).

The project aimed to test the potential to use existing surface water drainage charge mechanisms to incentivize increased implementation of Sustainable Urban Drainage Schemes (SuDS) to improve flood resilience and improve water quality in the city of Manchester (ref 1). Working with partners from The Water Taskforce, and funded by the DEFRA (Department for Environment, Food & Rural Affairs, UK Env agency), BITC (Business in the Community) and CLASP, these partners have been testing the concept that implementing SuDS on a school site could generate savings for a school, by reducing their hard-standing area and so their charges from their water supplier. Working with two schools in Manchester, the project team carried out detailed audits and SuDS interventions were identified that could divert or slow the flow of water into the sewer system, or reduce the amount of chargeable hard-standing area. Using this information, a trial version of a simple, user-friendly tool has been developed to help schools identify if there may be a cost-effective way to drop a chargeable surface water band (ref. 2).

Number One First Street is at the corner of Medlock Street and Whitworth Street behind the train arches near Oxford Road Station in the city center of Manchester (ref. 6). During the redevelopment of the former BT building now called Number One First Street a green roof was installed (ref 2). Whilst the vegetation slowly established, it provided a habitat for invertebrates and insects. A green wall, accommodating 37,000 plants was planned to be installed by 2020 which would replace glass, plastic and metal cladding with greenery (ref 1).

Wigan Flashes Project is encouraging natural re-colonisation to a site of very high conservation value and an enormous asset for recreation for the local community. The Wigan Flashes are a group of eight shallow wetlands, formed originally as a result of mining subsidence, which extend south from near Wigan's town centre. Over time, the industrial landscape has evolved in to a mixture of open water, reedbed, mossland, willow carr and fenland (ref 1).

An environmental improvement programme has helped to clean up a previously derelict plot of land on one of Belfast’s main thoroughfares, by transforming it into a community garden. A vegetable garden was officially launched in July 2009 at Walkway Community Association, on Finvoy Street in east Belfast. The scheme is part of Belfast City Council’s ongoing £150 million Investment Programme of work across the city. (Ref 1, Ref 5)

The city of Salford has experienced several floods and is at risk of flooding once every 100 years (Ref1). The majority of properties in the city that lie in a high-risk flood zone are in the floodplain of the Irwell. The UK's Environment Agency and the council, designed a flood prevention scheme which included temporary water storage areas which will store floodwater on the existing Castle Irwell playing fields and public open space, and double as sports area otherwise (Ref 5). It aimed to have its own wetland and wildlife habitat, and will help protect hundreds of homes and businesses (Ref 4).
