NRK: Many municipalities are planning construction projects on quick clay areas designated as risk zones
In several places in Norway, large construction projects are planned in quick clay areas with a higher risk of landslides than in Gjerdrum, according to Norwegian Broadcasting (NRK).
NRK has looked at areas around the country where the Norwegian Water Resources and Energy Directorate (NVE) believes that there is at least the same risk of landslides as in Gjerdrum.
Several municipalities approve and plan larger construction projects in such quick clay areas, according to the overview.
One of the construction projects planned in an area where the NVE believes the level of danger is high is a project in Åfjord Municipality on the Trøndelag coast.
Danger levels
The NVE has assessed the level of danger for quick clay landslides at level 22. In comparison, the landslide area in Gjerdrum had a danger level of 17.
Åfjord Municipality says that they have been aware that there is quick clay in the Municipality’s downtown area. This became a topic when they discussed where the new project should be located, but their investigations showed that the ground conditions were stable enough.
“We have had consultants for both geotechnics and construction who have made their assessments. We can only trust them,” Lars Helge Kolmannskog, the section manager for agriculture and technical services in the Municipality, said.
