1. General information
2. Objectives of the intervention
Goals of the intervention
The goal of the intervention was to reduce the stormwater load on the recipient (Risebergabäcken) from an area with a large proportion of hard surfaces. In addition, to cut water flow peaks, increase biodiversity, increased accessibility and recreation (ref. 2).
Quantitative targets
The recommended design looked like:
Slopes - 1:4 - 1:20; At a distance of 0.5 m from the beach edge, the depth of water should not exceed 0.2 m, to avoid hidden hazards. The recommended maximum depth in the center of the plant/system was 1 m; No fencing; Plant and species choices are adapted to the current conditions (ref. 2).
"The maximum water flow from the area is 1.5l/s and ha."
"At least 50% of the stormwater from hard surfaces shall be led over permeable surfaces, where the water is allowed to be delayed before reaching the municipal system." (ref. 2, 3).

Monitoring indicators defined
maximum water flow in l/s and ha/s;
% of storm water led over permeable surfaces (ref. 2)

Sustainability challenge(s) addressed
Habitats and biodiversity conservation: What types of conservation goals are / were defined for the NBS intervention?
Habitats and biodiversity conservation: What activities are implemented to realize the conservation goals and targets?
Implementation activities
An ecological stormwater system was created; with a new green oasis with the purpose of delaying and cleaning water (as well as preventing erosion and floods) (ref. 1).

The document 'Ecological storm water management' (sv. Ekologisk dagvattenhantering) from 2011 mentions other examples, such as Toftanäs wetland park (sv. våtmarkspark), and Ekostaden Augustenborg (different solutions in the district). (Ref. 2)
Replicability/Transferability

The Malmö City’s Action Plan for Climate Change mentions Risebergabäcken as "National Demonstration Area". (Ref. 6)
Examples from Risebergabäcken are also included in "Skyfallsplan för Malmö" (storm water plan) from 2016.
