Sea defences

A plan on sea defences is made according to legislation on the transport plan, and is specified in the chapter on maritime plan. In the preparation of plans on sea defences, IRCA collaborates with the municipality in question, landowners and other parties to the case.


Plan on sea defences

According to the transport plan, continuing work on the sea defences is expected during the scheduling-period. The work is carried out in co-operation with municipalities or landowners, that carry at least 1/8th of the cost. When allocating funds, a triage model that takes account of marine erosion and the value of the eroding area is used. The need for the construction of sea defences is expected to increase due to the rising sea level caused by global warming and tectonic movements. Furthermore, many sea defences are worse for wear and in need of renovation or reinforcement.

The Treasury pays for up to 7 out of 8 parts of the cost of preparation and construction of sea defences. Landowners and municipalities, that benefit from protective measures on their land, pay at least 1/8th, and the cost is divided between the landowners with respect to the size of the land and the coast that needs to be defended.

Law and regulation

Documents in Icelandic


Funds for sea defences due to flood risk or land erosion caused by the intrusion of the sea, are available. Habited areas and areas with structures or cultural heritage have priority when it comes to the construction of sea defences. It should be pointed out that Article 5 of Act No. 28/1997 on sea defences, stipulates that the area, as well as the structures, shall have been processed in accordance with planning law. All suggestions or wishes expressed by the municipalities on places where structures or other things of value are in danger due to tidal floods or land erosion, will be evaluated, assessment of construction and cost carried out, and projects placed in an order of priority.
