A New CALL Copenhagen project funded by the Danish Water Sector’s Development and Demonstration Program will create the basis for a more efficient realization of “climate streets” in order to support a sustainable green and blue climate adaption.

The project “Climate Adaptation – On the Other Side of the Fence” will develop and test participatory planning methods for local climate road project, as well as categorise and document the effect of the technical standard elements in a climate street.

Up to half of the sealed areas in cities are made up of streets that consequently contribute massively to the water run-off from a city. Thus, the development of “climate streets”, which can retain water and reduce the load in the sewer system, is an important part of a sustainable climate adaptation. In Copenhagen alone, hundreds of streets must be converted into climate street as part of the current Copenhagen Cloudburst Plan. This implies their permanent decoupling from the existing sewage system.

Many other Danish cities, including Frederiksberg, Middelfart, Vejle and Aarhus, are also working intensively with climate streets. Hence, climate adaptation comes close to many private landowners who need to be involved in the planning process. Either because they use the streets daily or because they have to guide rainwater from their own land parcel to the new climate street in order to secure their property against flooding.

In order to implement such a large number of projects in a cost-effective manner, it is necessary to apply procedural as well as technical standard components that can be used across the country.
