A recreational area in Lynge is helping to increase biodiversity, optimize rainwater management and protect the land against flooding.
In recent years, the recreational area Lynge Fælled, which offers visitors an urban nature experience, has been challenged by flooding. Heavy rains have led to buildings being at risk of flooding and the possibility of overloaded sewers contaminating lakes and streams. The municipality has responded by creating a new rainwater solution to climate-proof the city and improve conditions in the stream Lynge Å. By remodelling the landscape with depressions and lakes, up to 2,000 m3 of rainwater can be stored in the reservoirs and released into the drainage system at a manageable rate.

CLIMATE-PROOFED BUILDINGS, INCLUDING SCHOOLS AND NURSERIES
The project has been developed in collaboration between Allerød Municipality, the University of Copenhagen, Novafos and Watercare. The project demonstrates how, rather than being stored in sewer pipes, surplus water can be integrated as a natural feature in urban and residential settings.
The project's botanical and recreational priorities allow the citizens to enjoy a community rich with nature.
Together, the project partners have developed innovative methods that not only contribute to climate-proofing the area, but improve water quality and recreational spaces in Allerød. In addition to nature-enhancing initiatives such as temporary lagoons, reservoirs and a permanent lake, the project focuses on water purification. Connected to the project, a double porous filter has thus been developed to ensure high water quality and thriving green areas.
How the Global Goals are addressed
Clean Water and Sanitation
With water purification efforts and a more stable flow of water, the municipality expects to achieve significantly higher water quality in the nearby streams and lakes.
Climate Action
The recreational project came about from the municipali- ty's wish to floodproof the area Lynge Fælled so that it will withstand a 1-in-25-year rainfall event.
Life on Land
The project seeks to improve biodiversity by bringing more than 40 new plant species to the area and creating good biotopes, especially for amphibians such as salamanders.
Allerød Municipality
Allerød Municipality covers an area of 67 km² land on the island of Zealand in eastern Denmark.
