Bjerkedalen is a recently constructed park around the Hovin creek in Bjerke District. It is situated in the middle of a settlement block, which used to have few public spaces. The park now acts as a recreational area with lots of green space, a river and several facilities for outdoor activities. The construction of Bjerkedalen park incorporated the installment of several important blue-green structures and features such as planting native trees and plants along the river, providing open grassy areas as well as reopening the Hovin river from underground pipes, with the aim of improved water quality and flood prevention.(Ref. 2)

Project objectives

The Bjerkedalen Park and reopening of the Hovin River were part of wider municipal plans and strategies which included the following goals: - Adaptation to a changing climate - Better water quality and a strengthened urban ecology - Increased possibilities for an outdoor life and increased public health (Ref. 1)

Implementation activities

- The river was reopened for improved water quality and flood prevention due to expected increase in rainfall as a consequence to climate change, and now flows open for 300 meters. - Kelps and other aquatic plants create habitats for fish in the water bodies of the park and there is a bathing pond which acts as a popular attraction on hot summer days. - The river banks are planted with native, water-loving species and there are plenty of trees planted on the slopes of the park. The park consists of 12 acres of flower beds, 6 acres of lawn as well as 50,000 perennials that altogether provide green surfaces and habitat for some species. - A green canal with stepped edges is created near the café - It has been made accessible to everyone in an exemplary way, with a low gradient on the hiking trails. (Ref. 2,3)
