Native title of the NBS intervention
Etablering af NyE
Short description of the intervention
“An integrated solution for groundwater, rainwater, waste water, streams and ponds creates attractive housing in a new suburb (NyE), with room for exciting architecture. The water cycle plays a key role in urban development in Denmark, and water is one of the ever-present elements in our lives. Århus needs to prevent flooding caused by climate change, avoid polluting our groundwater, and improve the environment in streams and ponds to allow the use of water to create recreational value for the residents. This way, Århus can build a balanced aquatic environment, which will ultimately create a better city.” (Ref. 1)

The establishment of the first stage consisting of 650 homes, day care center and grocery store was initiated in the autumn of 2016 after more than 10 years of planning, and in the summer of 2018, the first residents moved into Nye. More homes are on the way. (Ref 14). In its current form of just over 150 ha, it has a capacity of approx. 15,000-20,000 inhabitants or approx. 10,000 homes at full expansion (Ref 15)

Present stage of the intervention
Please specify "other" stage of the intervention
Started in 2006 and a plan for the area was developed in 2007 (Fremtidens forstad). In the year 2016 the first detailed plan was accepted, and after 10 years of planning, in the summer 2016 the new housings start and the first residents to move into the area are expected by the end of 2017 (Ref. 2, 3, 4)
Goals of the intervention
The objectives of the intervention are to integrate solutions for groundwater, rainwater, wastewater, streams and ponds that create attractive housing. The aims are to prevent flooding caused by climate change, avoid pollution in the groundwater and improve the environment in streams and ponds, and to use the water for recreational values. Green and blue spaces (mostly connected to water) are included in the vision of Nye. A long-term goal is the development of a climate park that can be created in the form of a nature reservation with marshy areas, trees and bushes, in the undeveloped area west of Nye. The climate park will make it possible to tackle extreme rainfall caused by climate changes over the next few years, through a collection of rainwater and controlled flooding into the park. (Ref. 1, 5)

A long-term goal is the development of a climate park that can be created in the form of a nature reservation with marshy areas, trees and bushes, in the undeveloped area west of Nye. (Ref 5)
Quantitative targets
Development of a sustainable district that will eventually house 15,000- 20,000 people. (Ref. 2, 15)
Also, the area provides the municipal water supply with around 20%. (Ref. 6)

Implementation activities
Using the integrated streams and ponds (which provide the possibility for architectural solutions) for outdoor activities. (Ref. 1)
"Aarhus Water and the Tækker Group are working to think up better ways of using rainwater integrated into the development plan right from the start. The project group is currently looking beyond the boundaries of the city for ideas and working on a development plan that incorporates them." (Ref. 13)
Also, NIRAS has developed an ambitious strategy for handling the water, which means to integrate rainwater as a recreational element, as well as to use water for toilet flushing. (Ref. 12)

The finished city is seen as an independent city with shopping opportunities, schools, day care institutions, sports facilities, medical center, cafes, church, playgrounds, etc (Ref 15)
The climate park will make it possible to tackle extreme rainfall caused by climate changes over the next few years, through collection of rainwater and controlled flooding into the park. (Ref. 1, 5); repurpose water: integrate rainwater as a recreational element, as well as to use water for toilet flushing. (Ref. 12)

Impacts, benefits
Description of environmental benefits
The impacts are yet unknown as the project is still ongoing. The objectives of the intervention are to integrate solutions for groundwater, rainwater, wastewater, streams and ponds that create attractive housing. The aims are to prevent flooding caused by climate change, avoid pollution in the groundwater and improve the environment in streams and ponds, and to use the water for recreational values. Green and blue spaces (mostly connected to water) are included in the vision of Nye. A long-term goal is the development of a climate park that can be created in the form of a nature reservation with marshy areas, trees and bushes, in the undeveloped area west of Nye. The climate park will make it possible to tackle extreme rainfall caused by climate changes over the next few years, through collection of rainwater and controlled flooding into the park. (Ref. 1, 5)
“The results include better water quality in streams and ponds, and physical conditions which encourage sought-after fish such as salmon and sea trout. The township is also climate-proofed to the extent that it can cope with most major cloudbursts, and the groundwater under-ground can continue to accumulate without pesticides seeping down.” (Ref. 1)
-rainwater and rainfall management were analyzed at the site of the intended new buildings. In Nye, all rainwater is handled on terrain in streams, ditches, ponds; roads are designed to act as waterways in the event of heavy rain fall and the water is to end up in a parking space instead of "the living room floor". (Ref. 11)
Description of economic benefits
Nye sets new standards for how a private developer can join forces with the local authority, water utility and consultants to create the town of the future, by focusing on a cohesive approach, balance and sustainability. (Ref. 1)

Ref 1,5: The objectives of the intervention are to integrate solutions for groundwater, rainwater, waste water, streams and ponds that creates attractive housing.

Ref 15: It will attract new residents and it will make the existing residents feel a significant quality of life by just being a part of this community.
Please specify other environmental justice issue
“The results include better water quality in streams and ponds, and physical conditions which encourage sought-after fish such as salmon and sea trout." (Ref 1)
Description of social and cultural benefits
Nye is created with a starting point that is green and sustainable - and this starting point will be the city's underlying identity. It will attract new residents and it will make the existing residents feel a significant quality of life by just being a part of this community. Nye must be sustainable in an environmental, economic and social sense. It must challenge the existing standards for sustainable construction and the existing technology in the field. It should form a good framework for the people who will live and work in Nye. It should be a city that people are proud to live in and happy to be neighbors to. The city must be able to offer an active city life in close contact with the surrounding landscape. The city will have shopping opportunities, schools, day care institutions, sports facilities, medical center, cafes, church, playgrounds, etc. (Ref 15)
