Sustainable stormwater solutions contribution to multifunctional surfaces

Summary

Densification in urban landscapes is increasing which creates more hard surfaces that contribute to increased stormwater flows. This leads to a conflict between the management of stormwater and other values ​​that are demanded on neighborhood land. Neighborhood land therefore needs to be more efficiently used. A possible solution is to create multifunctional surfaces through sustainable stormwater solutions. These solutions affect the management of stormwater, but can also contribute to biodiversity and the social values of neighborhood land. This paper investigates sustainable stormwater solutions and how they can contribute to multifunctional surfaces. The study was partly made through a theoretical application on a study area located in Uppsala, but also through a literature study. To understand how the study area could develop, illustrations were created. This to get an overview and to highlight surfaces which could develop into more multifunctional areas. The conclusion shows that it is possible to create multifunctional areas on neighborhood land. However, there are challenges for it to be done effectively. There is a complexity in that several stormwater solutions achieve the best results on larger surfaces, but neighborhood land often consists of smaller areas. In order to meet these challenges, a greater collaboration between private landowners and between private landowners and municipalities is needed, but also that the development of stormwater solutions continues to adapt to denser, narrower cities.
