Omprojektering av parkeringsytor : en väg mot multifunktionella gröna ytor

Sammanfattning: Densification that takes place in both Sweden and the rest of the world can lead to the nature around the cities being protected but can also mean that greenery and good habitats within the cities are lost. In the discussion about densification, the handling of unused surfaces is a factor. Many of these unused surfaces are parking spaces in residential areas that are in poor condition and in need of refurbishment. This study has dealt with whether the right design and choice of materials when reprocessing unused parking surfaces can lead to multifunctional surfaces. Surfaces that, through increased ecosystem services, are in line with sustainable urban construction. Lomma is one of Sweden's fastest growing municipalities, which means that there are major changes in the municipality's urban areas. At the same time as new areas for densification are investigated, there are clear goals within the municipality's urban planning to create close-up green areas that can benefit residents in the immediate area. Since the problems surrounding unused, worn-out parking areas are also present in the Lomma municipality, it is possible to create residential-close multifunctional surfaces. At present, the municipality has designed two surfaces with the aim of reducing the number of parking spaces, increasing green qualities and managing stormwater locally with permeable materials. Lomma municipality's local environmental goals focus on sustainable construction regarding ecology and health, reduction of traffic noise levels in residential environment and proximity to natural and green areas for residents in the municipality. The local targets also highlight the development of the municipality's green structure with the aim of increasing biodiversity, improving stormwater management, improving the outdoor climate and creating a long-term sustainable urban environment. In this study, the municipality of Lomma has acted as a reference point regarding the problem of unused parking areas and the work towards sustainable urban construction. The result of this study has shown that by creating areas where the hardened materials are reduced and vegetation are increased, small unused parking spaces can fill new functions. By promoting green environments, most ecosystem services that the surfaces contribute can increase. Ecosystem services such as stormwater management, increased air quality, reduced noise levels and increased biodiversity. In parallel with the development of the study, a guiding document has been created. Omprojektering av parkeringsyta – vägledning och utformningsförslag 2019 is a script that deals with design proposals, plant materials, stormwater solutions and biodiversity. These are aspects that are relevant when reconstructing parking areas.
