The industrial area Larsfrid-Vilhelmsfält in Halmstad will be transformed into a residential-, service- and educational area. Heavy cloudbursts in the future are more than today's stormwater- and sewer pipes can handle. There is a possibility to supplement the drainage system with blue-green solutions for planned management, retention and storage of stormwater from daily rain and pluvial flooding. The solutions also do other ecosystem services as reducing heat and support biodiversity and their multifunctionality make them suitable on valuable land. This work has studied opportunities for blue-green solutions, especially green roofs, permeable surfaces and multifunctional spaces in Larsfrid-Vilhelmsfält. The study questions have been How can Halmstad municipality work with blue-green solutions as a resource in Larsfrid-Vilhelmsfält? and Is it possible to point out spaces in the Larsfrid-Vilhelmsfält area for blue-green stormwater management? The method consists of a literature study, questions to municipal officials, study of downpour maps and visual inspections. The first study question has been answered trough advantages and disadvantages according to different blue-green solutions, different laws, the planning process, costs and benefits and examples from Malmö and Göteborg amongst others. The second question has been answered trough suggestions of blue-green solutions pointed out on an image of Larsfrid-Vilhelmsfält. The image is created from a map overlay of an orthophoto and information from a downpour map, information from aerial photos from Internet and visual inspections on site. The municipality of Halmstad has a chance to start early with sustainable urban drainage systems in Larsfrid-Vilhelmsfält. There are ways to calculate costs and maintenance. It is easier and more inexpensive to construct blue-green solutions before the area is finished, than after. Without it, it will be much more expensive to take care of the suffering and the physical costs caused by pluvial flooding.
