Smart rainwater management solves more problems in the cities

In the coming years, many larger cities have to come up with solutions for the challenges of increasing amounts of rainwater and more extreme weather. By implementing solutions that help protect densely populated and developed areas against flooding, the development of the square serves as an example to be followed when the rest of the city is to be climate-proofed. By actively making use of a city’s green areas in the fight against pollution and securing the city against cloudbursts, smart ways of handling rainwater solve a great deal of the problems, cities today are facing.

Linden trees close to the metro

Since the metro station on Kongens Nytorv was established in 2003, 23.700 passengers have daily gotten on or off the train on the historic square. In addition to this, many Copenhageners and tourists often enjoy a sunny day in Nyhavn or go for a walk in the city – both places situated close to the square.

From 2019 people visiting Kongens Nytorv have been able to enjoy the 80 linden trees forming a “crown” around the status of Christian V. The so-called “Krinsen” adds a green and impressive look to the square.

Elm trees replaced with linden trees

Before the linden trees, “Krinsen” was made up of elm trees. The elm trees were struck by elm disease and have today been replaced.

The new trees have been planted according to specific historic instructions to reach the same beautiful expression.

StrataCells instead of structural soil  

The original elm trees were planted in structural soil – a special mixture of soil and stone that is used for urban tree planting. However, in order to give the new trees the best growth conditions, the structural soil was replaced by 15.000 StrataCells and large amounts of uncompressed soil placed under the impervious surface of the square. The 15.000 StrataCells create a volume of about 925 m3.  

StrataCells is an advanced root-friendly soil cell system for tree pits that ensures optimal growth conditions for the roots of trees. They are ideal for roadways, roof gardens, and places with heavy traffic and restricted space under the pavement. Additional watering systems were installed to ensure that the trees get enough water – also during dry seasons.

Planted according to specific historic instructions  

The square was transformed in connection with the establishment of the new metro.

It was an extraordinary task to reestablish a square as iconic and historic as Kongens Nytorv. This was also the case for the design of the trees. The trees were temporarily planted at Birkholm plantage, where they took good care of the trees until the square was finished.

This was also the case for the tree pits, that needed to be customized and required specific skills from the entrepreneur of the project, Barslund.

At Milford we enjoyed working closely with COWI and the City of Copenhagen to ensure the historic value of “Krinsen”. Today the trees act as a beautiful green add-on to the iconic square and as an impressive sight.
