What the dataset contains
Marka boundary in Placepoint
The Marka boundary sets the area covered by the Marka Act (Act of 6 June 2009 No. 35 relating to natural areas in Oslo and nearby municipalities). It is a legal boundary that covers Oslomarka and nearby forest and outdoor recreation areas with a general ban on building and strict requirements for mitigation measures. The Act came into force in 2009. The geographical area itself is set out in a separate regulation from 2015, with minor adjustments adopted by the Storting in 2019.
For a property developer or investor in the Oslo region, the Marka boundary is one of the most important restrictions in practice that can stop a project. As a rule, plots inside the boundary cannot be developed, and even plots just outside it can face extra restrictions through consideration zones in zoning plans. The Ministry of Climate and Environment (Klima- og miljødepartementet, KLD) manages the dataset legally, while the national geodata services operate the map data. Part of the Nature map layer. See the Marka Act on Lovdata for the full regulations.
