Kuninkaantammi is a new energy- and eco-efficient residential district by the Vantaa River and Helsinki’s Central Park that is in the construction phase with a dense urban design, consistent with the ecological, experiential and community requirements of modern housing. It will become a climate-smart neighbourhood for 5,000 inhabitants. Environmental factors have already been noted in the zoning of the area, and energy efficiency guides the design and building processes. Kuninkaantammi will be a pilot project for stormwater runoff management in Helsinki using green infrastructure. The construction is ongoing (2013-2025). Management of storm waters in the area will be carried out through natural methods (ref. 1, 11).

Focus

Creation of new green areas, Maintenance and management of urban nature existing green areas, Creation of semi-natural blue areas, Transformation of previously derelict areas

Project objectives

1. To create a residential district with a strong sense of community that is adapted for a changing climate and changing rain patterns. 2. The natural stormwater management methods will be visible in the area as technical solutions integrated with the urban landscape, such as various pools and stone streams along the streets, vegetation dents, large trees, green rooftops on the buildings and rain gardens on the plots. The most important goals of the various methods are to 1) utilize flow peaks, 2) decrease the total run-off and 3) potentially improve the water quality. 3. To promote a higher quality of life, including parks for leisure opportunities and an aesthetically pleasing district design (ref. 1). 4. To make energy- and eco-efficient residential area (ref. 11). 5. To combine an urban environment with a village atmosphere for the residents to have enhanced social livability (ref. 11). 6. Parts of the central park areas will be sectioned off for urban agriculture, and rain water will be used for irrigation. Courtyard areas will contain gardens irrigated with rainwater (ref. 13).

Implementation activities

1. Create ponds and open water flows to control the flow to the rainwater drainage and prevent flooding of the roads in the area; 2. Create stone streams along the streets; 3. Create vegetation dents; 4. Plant large trees, 5. Create green rooftops, 6. Create rain gardens, 7. Create infrastructure to lead the water to wetland park Helene Schjerfbeck Park, 8. To create dammed ponds in the wetland park where the water will be led before being channelled to Mätäjoki and Vantaanjoki, 9. To create retention ponds in green areas to filter out impurities from the stormwater to prevent disturbance of the EU protective species (ref. 9, 10, 11,12, 13).
